摘　　要：高压开关柜大量应用于变电站、电厂和配电站房,具有体积小、密封、承载负荷能力强、运行可靠等特点,是变、配电系统的10kV主力设备,其安全可靠性直接影响广大用户的正常用电。配电网线路重过载、雷击或发生短路等原因会导致电缆发热、老化、绝缘破损,容易造成易燃物燃烧,引发火灾。本文结合开关柜结构特点,研究一种灭火装置及其控制系统来进行辅助灭火,以降低开关柜起火造成的损失。High-voltage switchgear is widely used in substations,power plants,and distribution station buildings.It has the characteristics of small size,strong sealing and load bearing capacity,and reliable operation.It is the major equipment of the 10kV transformation and distribution system,and its safety and reliability directly affect the power supply of users.Due to factors such as heavy overload,lightning strikes,or short circuits in the distribution network,cables may overheat,age,and insulation may be damaged,leading to the combustion of flammable materials and causing fires.This paper proposes a fire extinguishing device and its control system to assist in extinguishing fires and reduce losses caused by switch cabinet fires,based on the structural characteristics of the switch cabinet.
