Preferably, described temperature measuring equipment is temperature measurer.
Preferably, described treating apparatus is PLC.
The present invention has also adopted a kind of Temp. control method that adopts electric supply installation, and when being positioned at temperature that the panel box temperature measuring equipment detects and being higher than the first design temperature, treating apparatus is opened the first fan and the second fan.
Preferably, when the first fan and the second fan were opened, when the temperature that described attemperating unit detects was lower than the second design temperature, treating apparatus cut out the first fan and the second fan, and described the second design temperature is less than or equal to described the first design temperature.
Preferably, described the second design temperature is lower than 2 to 3 ° of described the first design temperatures.
Preferably, when the first fan and the second fan is opened and attemperating unit detects temperature not only were higher than the second design temperature but also are lower than the first design temperature, the first fan and the second fan were kept and are opened; When the first fan and the second fan cuts out and attemperating unit detects temperature not only were higher than the second design temperature but also are lower than the first design temperature, the first fan and the second fan were kept and are closed.
Preferably, described the first design temperature is 35 ℃～40 ℃.
The present invention adopts above structure, has the following advantages:
1, hot-air can be discharged the room, accumulate in panel box heat on every side with minimizing;
2, can reduce the start-up time of the first fan and the second fan, prolong the serviceable life of the first fan and the second fan;
3, can reduce the number of starts of the first fan and the second fan, prolong the serviceable life of the first fan and the second fan.
Description of drawings
Accompanying drawing 1 is the electric supply installation structural representation among the present invention.。
In the accompanying drawing: 1, room; 2, panel box; 3, the first fan; 4, the second fan; 5, treating apparatus; 6, temperature measuring equipment.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be those skilled in the art will recognize that protection scope of the present invention is made more explicit defining.
As shown in Figure 1, a kind of electric supply installation, this electric supply installation comprise panel box 2, cooling device, are used for the control system of control cooling device.
Panel box 2 generally is placed in the room 1.
Cooling device comprises the first fan 3 and the second fan 4.The first fan 3 is arranged in the panel box 2, and when the first fan 3 was opened, it can discharge panel box 2 with the hot-air in the panel box 2.The second fan 4 is arranged in the room 1 and is positioned at outside the panel box 2, and concrete, the second fan 4 is arranged on the wall in room 1, and when the second fan 4 was opened, it can discharge room 1 with the hot-air in the room 1, to reduce heat accumulation around panel box 2.
Concrete, the first fan 3 is placed on panel box 2 inside, offers a plurality of vent ports on the panel box 2, and hot-air is discharged from vent port.The second fan 4 is arranged on the wall in the room 1 that closes on panel box 2.
Control system is used for the switching of control the first fan 3 and the second fan 4.
Control system comprises temperature measuring equipment 6 and treating apparatus 5.Temperature measuring equipment 6 is positioned at panel box 2, and is concrete, and temperature measuring equipment 6 can be the device that thermometer, thermo-sensitive resistor etc. have measures ambient temperature.Treating apparatus 5 can be the various devices with the control function such as PLC.Behind the temperature value in temperature measuring equipment 6 detects panel box 2, treating apparatus 5 responds according to this temperature value, namely determines the switching of the first fan 3 and the second fan 4 according to the size of temperature value.
Adopt the Temp. control method of the electric supply installation among the present invention, when being positioned at temperature that panel box 2 temperature measuring equipments 6 detect and being higher than the first design temperature, treating apparatus 5 is opened the first fan 3 and the second fan 4; When the first fan 3 and the second fan 4 were opened, when the temperature that described attemperating unit detects was lower than the second design temperature, treating apparatus 5 cut out the first fan 3 and the second fan 4, and described the second design temperature is less than or equal to described the first design temperature.When the first fan 3 and the second temperature that fan 4 is opened and attemperating unit detects not only were higher than the second design temperature but also are lower than the first design temperature, the first fan 3 and the second fan 4 were kept and are opened; When the first fan 3 and the second temperature that fan 4 cuts out and attemperating unit detects not only were higher than the second design temperature but also are lower than the first design temperature, the first fan 3 and the second fan 4 were kept and are closed.Preferably, the second design temperature is lower than 2 to 3 ° of described the first design temperatures.Like this, the first fan 3 and the second fan 4 can be because of opening instantaneous temperature decline and closing immediately, can not open immediately because the turn-off transient temperature rises yet, if meeting that this thing happens and then damages the first fan 3 and the second fan 4 so that the first fan 3 and the second fan 4 start, close increased frequency.
Concrete, in the present invention, the first design temperature is 35 ℃～40 ℃, when the first design temperature was 35 ℃, the second design temperature was 32 ℃.When the first design temperature was 40 ℃, the second design temperature was 37 ℃.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
