Intelligent preassembled transformer substation and control method therefor

Abstract

The invention provides an intelligent preassembled transformer substation and a control method therefor, and the transformer substation comprises a main controller which is installed in a preassembledtransformer substation box body, a temperature and humidity controller which is connected with the main controller, an electric heating plate module, a refrigeration module, a fan, an illumination module and a fire extinguishing module, wherein the electric heating plate module, the refrigeration module, the fan, the illumination module and the fire extinguishing module are sequentially connectedwith the temperature and humidity controller. The electric heating plate module, the refrigeration module, the fan, the illumination module and the fire extinguishing module are connected in parallel. The refrigeration module comprises a compressor, an evaporimeter, an expansion valve and a condenser, wherein the compressor, the evaporimeter, the expansion valve and the condenser are connected sequentially. The fire extinguishing module comprises a fire extinguisher and a telescoping mechanism. An upper handle of the fire extinguisher is provided with a groove, and the telescoping mechanism comprises a motor and a telescoping rod. The upper end of the telescoping rod is provided with a zipper, and the zipper is sleeved by the groove of the upper handle. A spraying nozzle of the fire extinguisher faces the electric heating plate module. The transformer substation can reduce the probability of fire happening to the preassembled transformer substation. The transformer substation can employ the fire extinguishing module for automatic fire extinguishing especially during fire, and prevents fire from spreading.

Problems solved by technology

[0002] In the existing prefabricated substation box, there is a temperature and humidity intelligent control circuit. This circuit generally includes components such as a controller, a temperature and humidity sensor, a fan, and an electric heating plate. When the humidity exceeds the set value, the main controller will turn on the electric heating plate for heating to prevent condensation in the substation box. When the detected temperature value is too low, the main controller will also turn on the electric heating plate for heating to prevent The electrical components in the substation box are damaged by freezing and cracking, but it is easy to cause a fire if the electric heating plate is used for a long time; on the other hand, when the temperature value detected by the temperature and humidity sensor is too high, the fan will be turned on to cool down. The climate is getting warmer. In summer, the temperature in many places has exceeded 40°. At this time, the temperature inside the substation box will be higher. It is not enough to cool the temperature only through the fan. The probability of fire inside the substation box is very high; When a fire breaks out under certain circumstances, there is no fire extinguishing module inside the existing substation box. Therefore, once the substation box catches fire, the fire level cannot be controlled at all, which often leads to the scrapping of the entire substation and serious losses. It is an intelligent prefabricated substation that greatly cools down the inside of the substation box and can effectively control the spread of fire in the event of a fire.
