一种罐式断路器及其静端挡气装置
摘要：
本实用新型公开了一种罐式断路器及其静端挡气装置，罐式断路器静端挡气装置包括静绝缘支柱，静绝缘支柱上安装有静触座、挡气罩，静触座上设有排气孔，所述挡气罩上设有连通所述静触座的排气孔的泄压孔。由于挡气罩上增加了泄压孔，静触座开口喷出的热气流不会使挡气罩内部压力过高而导致挡气罩变形从而保证了断路器的绝缘水平。
摘要（英）：

The utility model discloses a tank type breaker and quiet end keeps off gas device thereof, the quiet end of tank type breaker keep off the gas device and include quiet insulating pillar, install the stationary contact seat on the quiet insulating pillar, keep off the gas hood, are equipped with the exhaust hole on the stationary contact seat, be equipped with the intercommunication on the fender gas hood the pressure release hole in the exhaust hole of stationary contact seat. Owing to increased the pressure release hole on keeping off the gas hood, thereby stationary contact seat opening spun hot gas flow can not make and keeps off gas hood internal pressure and too high and result in keeping off the gas hood and be out of shape the insulation level who has guaranteed the circuit breaker.
