Background technique

The capacitor equipment in the capacitor room will generate a lot of heat when it is working, and the heat should be discharged in time, otherwise it will affect the normal operation of the capacitor equipment in the capacitor room. At present, the cooling measures adopted in the capacitor room of the substation are to set up an air intake window at the lower part of the side wall of the capacitor room, set an exhaust window at the upper part of the side wall, and install an exhaust fan on the exhaust window, and the air intake window and the exhaust window are located on the same side On the wall, the outdoor air and indoor air are circulated through exhaust fans to dissipate heat and achieve cooling. Although such measures can remove part of the heat in the capacitor room, but because the capacitor room is relatively deep, after the outdoor air enters the capacitor room from the air inlet window, it can only flow through the capacitor equipment near the side wall and then be exhausted to the outside by the exhaust fan. As a result, the capacitor equipment in the capacitor room far away from the air inlet window and the exhaust window cannot get ventilation and heat dissipation, which affects the safe operation of the capacitor equipment.
