145 Motor spring mechanism of Gas Circuit Breaker for 145 GIS

摘要

PURPOSE: An electronic spring driving apparatus of a gas circuit breaker for 145KV gas insulated switchgear is provided to reduce the manufacturing cost and improve the quality by using an electronic spring driving method. CONSTITUTION: An electronic spring driving apparatus of a gas circuit breaker for 145KV gas insulated switchgear includes a closing spring, a closing latch, and a closing solenoid. The closing spring is compressed by using a motor and a worm wheel. The closing latch(4) is used for maintaining a compressed state of the closing spring and supporting the compressed load of the closing spring by using a first lever(8) and a second lever(9). The closing solenoid(5) is used for operating the first and the second levers.
