Abstract

The invention provides a substation high-voltage room ventilation system and a substation high-voltage room, which solves the problem that in the prior art, when the temperature of the equipment in the high-voltage room is high in summer and the heat cannot be discharged in a timely and effective manner, the insulation material will accelerate at high temperature. Aging and reduced insulation performance, the equipment operates in a high-risk state, and there are technical problems such as major safety hazards. It includes a convection air duct, a control device, and a temperature sensor; the temperature sensor includes a group of temperature sensors that monitor the temperature of the main transformer, a group of temperature sensors that are correspondingly provided at each busbar corner point, and a group of temperature sensors that are connected at each busbar. A group of temperature sensors three correspondingly provided with at the point. The invention can make the equipment in the high-pressure chamber run in a safe state, avoiding the safety hazard of high temperature in the high-pressure chamber.

Description

technical field [0001] The invention relates to a high-voltage room of a substation, in particular to a ventilation system for a high-voltage room of a substation and a high-voltage room of a substation. Background technique [0002] In hot weather in summer, due to the increase in electricity load and the current effect, the heat generated by the equipment will increase, which will increase the temperature of the high-voltage equipment room. The main parts of the heat include the main transformer, the corner point of the busbar and the connection point of the busbar. The heat generation is the largest, but the exhaust fan in the high-voltage equipment room needs to be manually started and stopped, which cannot play the role of exhaust and ventilation in time, and the heat cannot be discharged in a timely and effective manner. The temperature of the equipment in the equipment room is too high. Due to the material, the insulation material will age at a high temperature and th...
