1、 Product overview:

The utility model relates to a rain cover for a gas relay, which belongs to a rain cover for a gas relay in a substation. The utility model is composed of a left vertical plate, a top plate, a right vertical plate and a rear vertical plate, and the rear vertical plate is provided with a bolt connection hole. The utility model has the characteristics of simple structure and convenient disassembly, can effectively prevent rainwater from entering and solve the problem of misoperation of gas protection.

Application of rain cover in main transformer temperature control system: transformer remote temperature measuring device is a device for remote monitoring and control of transformer temperature in operation. When the main transformer is in normal operation, the actual temperature of the main transformer cannot be measured accurately when the temperature measurement error of the device is too large, so that the monitoring personnel cannot accurately locate the temperature range of the operating main transformer, which is not convenient for the operators to take corresponding measures, affecting the reliable operation of the transformer and seriously affecting the reliability of power supply.

Fault: the waterproof measures of gas relay of transformer body are not perfect. When it rains or the snow melts, water droplets are easy to drip into the junction box through the oil conservator. In some cases, DC grounding fault will occur, in others, the transformer protection will mistakenly send light gas signal or even heavy gas protection action, resulting in switch action on both sides of the transformer.
