Communication power supply is the important component part of communication system; in the construction of communication network; power supply is to guarantee the unimpeded necessary condition of communicating by letter; for guaranteeing the power supply safety of communication equipment; power supply is the communication equipment power supply by two supply lines at least, and fuse of series connection carries out the power circuit protection in every supply line.With two supply lines is the example explanation; in China; each telecom operators all has a large amount of old equipment need upgrade replacement every year; in the charge cutting construction of communications equipment room power supply; supply line need be unloaded with ew line respectively and be replaced; and when a supply line disconnects; the load current of equipment can all be superimposed upon in another supply line; because the long-term use of fuse; and the aging other reasons that waits; its current-carrying performance also is difficult to guarantee, will make it fuse because of the electric current that is passed through is excessive, and because direct current load cutover level protection without male offspring; directly dead electricity is out of service for outage back communication equipment, thereby causes the communication disruption accident.In constructing operation,, cause the interruption of circuit in addition in case the situation of meeting accident also can make aging fuse blows.
Now need to provide a kind of new device in order to improve or to address the above problem.
The utility model content
The technical problems to be solved in the utility model is: protection and monitoring device that a kind of communication power supply is provided; to avoid in the construction of communication power supply equipment; because one supply line disconnects; make another supply line fuse owing to long-term use aging reason, with and carrying superimposed current or the transient high-current that causes because of other reasons; make fuse blows; the communication equipment dead electricity is out of service, causes the accident of communication disruption.
The utility model solves above-mentioned technical problem by such technical scheme:
A kind of protection of communication power supply and monitoring device; the electric power system that is used for communications equipment room; it comprises power supply and a plurality of communication equipment; power supply is the communication equipment power supply by many supply lines; fuse of series connection in every supply line; carry out power circuit protection, wherein, the protection of described communication power supply and monitoring device are can be at least in parallel with the fuse of a supply line wherein.
As further improvement, the connected mode of the protection of described communication power supply and monitoring device and fuse is a plug-in.
As further improvement, the protection of described communication power supply and monitoring device also comprise the monitoring modular that is used to monitor electric current, voltage or temperature by this device.
As further improvement, the protection of described communication power supply and monitoring device also comprise the display module that is connected with monitoring modular, are used to the electric current, voltage and the temperature that show that monitoring modular monitors.
As further improvement, described display module is a LCDs.
As further improvement; the protection of this communication power supply and monitoring device also comprise the alarm module that is connected with monitoring modular; when electric current that monitoring modular monitored or voltage or temperature reached the warning threshold values that this monitoring modular sets, alarm module can send alarm.
As further improvement, described alarm module comprises the trouble light that at least one is used to alarm.
Compared with prior art, the utlity model has following advantage:
1, the protection of this communication power supply and monitoring device are connected in parallel on the fuse of supply line; make this device with its fuse in parallel can bear jointly in the cutover operating process of construction power supply; superimposed current that is produced and transient high-current; with this normal operation of guaranteeing communication equipment, guaranteed the unobstructed of communication.
2, by this device monitoring module, display module and alarm module, can make operating personnel in work progress, the correct in real time actual situation of grasping the operation of load power consumption equipment, and take appropriate measures according to this situation, guarantee the fail safe and the reliability of work progress, guaranteed the safety of communication equipment.
Description of drawings

Fig. 2 is the framework schematic diagram of protection of the utility model communication power supply and monitoring device.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
The utility model provides a kind of protection and monitoring device of communication power supply, and this device is used for the electric power system of communication equipment.In present communication equipment electric power system, be that a plurality of communication equipment power supplies or a power supply are that communication equipment is powered by many supply lines normally by power supply, when one tunnel supply line is de-energized, then the electric current of power supply output is loaded in other supply lines, is that example is described as follows with two supply lines.
As shown in Figure 1, power supply is the communication equipment power supply by two a1 of supply line, a2, and fuse R1, a R2 respectively connect in two supply lines.In the charge cutting engineering of communication power supply equipment; before the a1 of supply line cuts off; at first that the protection and the monitoring device 10 of communication power supply is in parallel with the fuse R2 on the a2 of supply line; when the a1 of supply line disconnects; the protection of communication power supply and monitoring device 10 can with fuse R2, bear original electric current jointly by fuse R1 and fuse R2.Like this in the process of power supply to the communication equipment power supply; the protection of communication power supply and monitoring device 10 have been born owing to the a1 of supply line disconnects superimposed current and the transient high-current that produces simultaneously with fuse R2, have guaranteed the normal operation of the unobstructed and communication equipment of communication power supply.In addition, the connected mode that the protection of communication power supply and monitoring device 10 are connected with fuse R2 is that plug-in connects, and has not only made things convenient for installation but also guaranteed the firm and stable of contact.
As shown in Figure 2, the protection of communication power supply and monitoring device 10 further comprise monitoring modular 1, display module 2 and alarm module 3.Monitoring modular 1 links to each other with display module 2 and alarm module 3 respectively.
Monitoring modular 1 is used to monitor by the protection of communication power supply and electric current, voltage and the temperature of monitoring device 10, and the numerical value that monitors is sent to display module 2 and alarm module 3.In case detected numerical value has surpassed the warning threshold values of monitoring modular 1 inner setting, then starts alarm module 3 and reports to the police.
The above-mentioned improvement that the utility model has been done makes operating personnel in construction, can be held in the real-time condition of moving with communication equipment by correct in real time handle, and take appropriate measures, and has guaranteed the fail safe and the reliability of operating process, has guaranteed the safety of communication equipment.
