Description
Technical Field
The invention relates to the technical field of overcurrent protection, in particular to a surge protection module and a surge protector.
Background
With the development of technology, more and more electrical equipment is used by people, and the internal structure is more and more precise and sensitive. However, due to the switching of the power supply, short-distance lightning strike and the like, lightning surge, namely, sudden overvoltage with extremely short maintenance time and high peak value, often occurs in the power line of the electrical equipment. Such high voltages are very damaging to the components of the electrical device. As a result, various types of surge protectors are often employed to protect electrical equipment in a line.
The surge protector is a common low-voltage surge protector, and is in a high-impedance state under normal conditions, and once a line is subjected to surge due to lightning stroke or other reasons, the surge protector is conducted in a very short time, lightning current or overvoltage is led into the ground through a grounding wire, so that electrical equipment on the line is protected, and when the lightning current which cannot be born by a common surge protector for a long time and larger energy is met, a graphite gap is generally selected as a protector for larger lightning current.
Under normal conditions, when the continuous current of the surge protector is overlarge in a power supply line, the heat of a graphite gap component in the surge protector is increased, overheat burning of the surge protector can occur, at the moment, a thermal tripping device is required to be arranged in the surge protector, and the power supply line and the graphite gap component are disconnected by the thermal tripping device, so that the purpose of preventing the surge protector from igniting and burning is achieved.
When the lightning current born by the graphite gap is in an bearable range, the conventional tripping device is used for tripping in advance; or because the graphite gap has a follow current problem and because the follow current blocking capacity is larger, the tripping device can trip before the graphite gap is subjected to the follow current blocking operation because of larger follow current, and the problem of abnormal reduction of the service life of the graphite gap is caused. However, if the mode of forcibly increasing the current capacity of the tripping device is adopted, the normal protection requirement of the graphite gap can be borne, and when the system overvoltage needs the graphite gap to be truly segmented with the main loop, the problem of graphite gap ignition and combustion caused by too slow reflection speed of a low-temperature welding spot of the tripping device due to the increase of the heat capacity of the tripping device caused by the increase of the current capacity of the tripping device can occur.

In a preferred embodiment, the graphite gap assembly 120 includes a third electrode, a fourth electrode, a plurality of graphite electrodes, and a plurality of spacers disposed between two graphite electrodes, the third electrode and the fourth electrode being respectively connected to one graphite electrode.
In a preferred embodiment, the surge protection module 100 further includes a bracket disposed within the mounting member 140 and connected to the first side plate 142, the second side plate 144, and the third side plate 146, respectively, and a graphite gap assembly 120 is disposed on a side of the bracket away from the second side plate 144. It will be appreciated that brackets are used to secure the graphite gap assembly 120 to prevent any movement of the graphite gap assembly 120 within the mounting member 140.
The arc shielding plate 110 covers the mounting member 140, and meanwhile, the arc shielding plate 110 is provided with a through hole and is arranged between the graphite gap assembly 120 and the tripping assembly 130, and the piezoresistor arranged on the third electrode can be exposed from the through hole.
The arc shield 110 is used to isolate the trip assembly 130 from the graphite gap assembly 120 when the two are disengaged to avoid line accident enlargement.
In a preferred embodiment, the arc shield 110 is provided adjacent to both sides of the first side plate 142 and the third side plate 146 with a positioning rod for engaging the trip assembly 130 to move the arc shield 110.
One surface of the trip assembly 130 is connected to the second side plate 144, one end of the trip assembly 130 is connected to the third electrode, and the other end of the trip assembly 130 is connected to the fourth electrode. The trip assembly 130 is configured to move the arc shield 110 when the current is excessive, so that the arc shield 110 can isolate the trip assembly 130 from the graphite gap assembly 120.
Referring to fig. 3, in a preferred embodiment, the trip assembly 130 includes a trip elastic sheet 132, two elastic elements 134 and a low-temperature welding stage 136, the low-temperature welding stage 136 is disposed at one side of the third electrode of the graphite gap assembly 120, one end of the trip elastic sheet 132 is connected with the low-temperature welding stage 136 through a through hole disposed on the arc shielding plate 110, the other end of the trip elastic sheet 132 is connected with the fourth electrode of the graphite gap assembly 120, one end of the two elastic elements 134 is fixedly connected with two ends of the second side plate 144, which are close to one side of the graphite gap assembly 120, and the other ends of the two elastic elements 134 are respectively movably connected with two positioning rods.
It should be noted that the trip elastic sheet 132 should have a conductive function. The connection between the trip spring plate 132 and the low temperature welding stage 136 is provided with a plurality of through holes, and the heat capacity of the trip assembly 130 can be reduced by arranging the through holes, so that the trip reaction speed is improved.
The elastic element 134 may be, but is not limited to, a spring, a tension spring, etc. The number of the elastic members 134 may be 3 or 4, and is not particularly limited herein.
The low temperature soldering stage 136 includes a first connection portion, a second connection portion, and a third connection portion. The first connecting portion, the second connecting portion and the third connecting portion are sequentially connected, the first connecting portion and the second connecting portion are connected with the graphite gap assembly 120, and the third connecting portion is connected with the tripping elastic sheet 132. The first connecting portion and the second connecting portion are provided with a plurality of through holes, and the heat capacity of the low-temperature welding table 136 can be reduced by arranging the through holes, so that the tripping reaction speed is improved.
The low temperature soldering stage 136 has a larger flow capacity and a smaller heat capacity. Therefore, by setting the low-temperature welding table 136, the surge protection module 100 can also ensure that the tripping speed is high under the condition of bearing the normal protection requirement of the graphite gap assembly 120, so that the problem of the ignition of the graphite gap assembly 120 caused by slow response of the traditional tripping assembly is avoided, and the service life of the surge protection module 100 is prolonged. In addition, the provision of the low temperature solder station 136 also ensures that solder is prevented from directly contacting the graphite gap assembly 120 when the graphite gap assembly 120 heats up causing the solder to dissolve.
The first electrode 172 is located between the trip elastic sheet 132 and the mounting member 140, two ends of the second electrode 174 are respectively connected to the mounting member 140, and the second electrode 174 is disposed opposite to the first electrode 172. Specifically, the first electrode 172 is embedded in the second side plate 144, and two ends of the second electrode 174 are respectively connected to one ends of the first side plate 142 and the third side plate 146, which are far away from the second side plate 144.
Referring to fig. 4, the first indicator plate 112 is disposed on a side of the arc shielding plate 110 near the third side plate 146, and the second indicator plate 150 is disposed on the mounting member 140 and below the first indicator plate 112. The first indicator plate 112 and the second indicator plate 150 are used for displaying the current state of the surge protection module 100.
It should be noted that the first indicator board 112 and the second indicator board 150 should have different color marks, and the specific color is not limited herein.
Referring to fig. 5, the housing 160 is used for mounting the arc shielding plate 110, the graphite gap assembly 120, the trip assembly 130 and the mounting member 140, and the arc shielding plate 110, the graphite gap assembly 120, the trip assembly 130 and the mounting member 140 are disposed in the housing 160. In addition, the housing 160 is provided with a display window 162, and the first indication plate 112 may be exposed through the display window 162.
The working principle of the surge protection module 100 is as follows: when a line encounters lightning stroke exceeding a bearing range or abnormal system overvoltage, the interior of the graphite gap assembly 120 rapidly heats, so that the temperature of the surface of the graphite gap assembly 120 is increased, the temperature of the low-temperature welding table 136 is increased, the low-temperature welding table 136 is separated from the low-temperature welding table 136 through the tripping elastic pieces 132 connected with low-temperature soldering tin, at the moment, the positioning rods at two sides of the arc shielding plate 110 move under the action of the two elastic elements 134, and the arc shielding plate 110 rapidly moves between the low-temperature welding table 136 and the tripping elastic pieces 132, so that the low-temperature welding table 136 is completely separated from the tripping elastic pieces 132, and the conditions of wire drawing adhesion, arc discharge and the like after soldering tin hot melting are avoided; in addition, as the arc shield 110 moves, the first indicator plate 112 moves with the arc shield 110, exposing the second indicator plate 150 positioned below the first indicator plate 112 to alert the user to the failure of the surge protection module 100.
Second embodiment
The embodiment of the invention also provides a surge protector 300 for protecting electrical equipment in a circuit. Referring to fig. 6 and 7, a schematic structural diagram of a surge protector 300 according to an embodiment of the invention is shown. The surge protector 300 includes a base 200, a surge protection module 100, and the surge protection module 100 is detachably connected to the base 200.
It should be noted that, the basic principle and the technical effects of the surge protection module 100 according to the embodiment of the present invention are the same as those of the above embodiment, and for brevity, reference should be made to the corresponding contents of the above embodiment.
Referring to fig. 8, a schematic structural diagram of a base 200 according to an embodiment of the invention is shown. The base 200 is provided with a first groove 210, and the surge protection module 100 is embedded in the first groove 210. The first groove 210 is provided with a first chute 220, a second groove 230 and a third groove. Specifically, a first sliding groove 220 is disposed in the middle of the bottom of the first groove 210, two ends of the bottom of the first groove 210 are respectively provided with a second groove 230, and two side walls of the first groove 210 are respectively provided with a second sliding groove 240.
In addition, a control switch is disposed in the first chute 220, and is electrically connected to a remote signaling port disposed on the base 200, where the control switch is configured to generate an alarm signal when a control lever is pressed down by an object, and send the alarm signal to a remote intelligent terminal through the remote signaling port.
In this embodiment, a first slider 114 is disposed on a side of the arc shielding plate 110 near the first side plate 142, and the first slider 114 cooperates with a first sliding slot 220 disposed in the first groove 210, when the first slider 114 slides over the control switch, a control lever of the control switch is triggered to generate an alarm signal, and the alarm signal is sent to a remote intelligent terminal through a remote signaling port.
As can be appreciated, when the circuit encounters a lightning strike exceeding the bearing range or an abnormal system overvoltage, the interior of the graphite gap assembly 120 heats rapidly, which causes the temperature of the surface of the graphite gap assembly 120 to rise, so that the soldering station 136 is separated from the soldering station 136 by the trip elastic piece 132 connected with the soldering tin, at this time, the positioning rods on both sides of the arc shielding plate 110 move under the action of the two elastic elements 134, so that the first slider 114 moves in the first chute 220 along with the movement of the arc shielding plate 110, thereby triggering the control rod of the control switch, and generating an alarm signal to remind the user.
In this embodiment, the first electrode 172 and the second electrode 174 penetrate through the housing 160, and the second groove 230 is provided with a spring plate, so that the surge protection module 100 can be stably mounted on the base 200 and form a reliable electrical connection by matching the first electrode 172 and the second electrode 174 with the second groove 230.
The second sliding blocks 180 are respectively arranged on two sides of the housing 160, and the surge protection module 100 can be further fixed on the base 200 through the cooperation of the second sliding blocks 180 and the second sliding grooves 240, and meanwhile, the situation that the surge protection module 100 is inclined due to the fact that after the surge protection module 100 is plugged in and pulled out for many times, the first electrode 172, the second electrode 174 and the second groove 230 are not tightly matched can be avoided, and the electrical connection is unreliable when the surge protection module 100 is installed in the base 200.
It should be noted that the positions of the second slider 180 and the second chute 240 may be interchanged.
