Abstract
This paper designs a set of oil filter device of hydraulic mechanism
which can realize the emergency elimination of circuit breaker without power supply when frequent defects occur in the mechanism. The device is compact with simple wiring and light weight.The power supply adopts single-phase AC 220 V
and the oil pump motor has the function of over-current and over-heat protection. The feasibility of the device is verified by a large number of practical experience in substations
which greatly improves the maintenance efficiency of hydraulic circuit breakers and reliability of power supply.
