高压开关柜活门安全机械联锁装置

Safety flexible-gate mechanical interlocking device of high-voltage switch cabinet

Abstract

A valve safety mechanical interlock device for high voltage switchgears consists of a high voltage switchgear cabinet body and a high voltage switch arranged therein, a vacuum circuit breaker and a current transformer. The high voltage switch and the current transformer thereof are provided in the cabinet body, the vacuum circuit breaker is arranged on a switch car, the switch car is mechanically interlocked with a valve by a push rod and a valve crank arm, a slide block is provided on the switch car frame. A support is fixed on the cabinet body, the support is arranged with a slide bar which is corresponding to the slide block#GB001s position on the switch car and a lock pin integrally connected with the slide bar. An elastic element is provided on one side of the slide bar, a lock ring is connected with the lower part of the valve crank arm, a keyhole is arranged on the lower part of the lock ring at a position which is corresponding to the lock pin. The utility model has a simple structure and a reliable performance. The locking and unlocking are spontaneously realized during the course of the switch car#GB001s moving in and out of the cabinet body, the mechanical interlock of an active protection door and the switch car can be ensured.
一种高压开关柜活门安全机械联锁装置,主要包括一高压开关柜柜体和设于柜体内的高压开关、真空断路器和电流互感器,其中高压开关与电流互感器固设于柜体内,真空断路器安装在开关车上,开关车通过推杆和活门拐臂,与活门机械联锁,在开关车架上设有一滑块;在柜体上固定一支架,支架上设有一与开关车上的滑块位置相对应的滑杆和一与该滑杆连为一体的锁销,在滑杆一侧设一弹性元件;活门拐臂的下方接一锁环,该锁环下部与锁销相对处设有一锁孔。本实用新型结构简单,功能可靠,且上锁与解锁均在开关车进出柜体的过程中自然实现,可以确保活动防护门与开关车的机械联锁。
