断路器液压机构频繁打压处理分析及自动排气辅助装置设计

Analysis and Treatment on the Frequent Bulge of Hydraulic Mechanism for Circuit Breaker and Design of Automatic Exhaust Auxiliary Device

针对变电站内断路器液压机构运行过程中液压油混入空气,造成断路器频繁打压问题,结合西门子3AT2EI断路器特点,对该问题进行分析,设计出一种新型自动排气辅助装置,以提高断路器的运行可靠性。

In view of air is mixed into hydraulic oil during the operation of hydraulic mechanism for circuit breaker in the transformer substation,causing frequent bulge of circuit breaker.Combining with the characteristics of Siemens 3 AT2 EI circuit breaker,a new automatic exhaust auxiliary device is designed to improve the reliability of the circuit breaker.
