The invention provides a switchgear capable of effectively preventing burning arc leakage accidents. The switchgear is internally provided with an air passage; a draught fan is arranged on the air passage; an air inlet and/or an exhaust port of the air passage are/is arranged on the switchgear; and the air inlet and the exhaust port are provided with a burning arc leakage prevention device. According to the switchgear capable of effectively preventing burning arc leakage accidents provided by the invention, when burning arc accidents occur, the burning arc leakage prevention devices are automatically closed under the effect of high-pressure burning arc gas, and then ventilation holes formed when the air passage is designed are indirectly closed, so that the burning arc leakage accidents can be effectively prevented, and the personnel safety is guaranteed. 本发明提出了种能有效防止燃弧泄漏事故的开关设备，所述开关设备内设有风道，风道上装有风机，所述风道的进气口和/或排气口设在开关设备上，所述进气口和排气口上设有防燃弧泄漏装置。本发明的能有效防止燃弧泄漏事故的开关设备，当燃弧事故发生时，防燃弧泄漏装置在高压燃弧气体的作用下自动关闭，进而风道设计时所开的通风孔被间接关
