浅析输油泵站断路器拒合的原因分析及对策

THE SHALLOW UNPACK PETROLEUM PUMP STATION CIRCUIT BREAKER IS OC-CUPYD CAUSE CLOSED ANALYSIS AND COUNTERMEASURE

公司下属的各输油泵站35kV变电所进线柜大多采用隔离刀闸和断路器组合方式,隔离刀闸装设联锁装置,即防止带负荷分、合隔离刀闸。各输油泵站在合进线断路器的操作时,时有发生断路器拒合现象,严重影响全线的安全输油生产,并通过分析断路器拒合的原因,制定了相应的对策,有效地解决了这一问题。

Each the petroleum pump station 35kV transformer substation of my corporation subordinate advances the thread cupboard to use keeping apart knife floodgate and the circuit breaker combination method mostly, and namely the isolation knife floodgate is installed the interlock device, prevents taking the load branch and closes the isolation knife floodgate. Each petroleum pump station closes into the thread circuit breaker during the operation, the time has the circuit breaker occurring to occupy together the appearance, the safety of serious influence all fronts is lost oil production, and this text passage analysis circuit breaker is occupyd the cause together,and has laid down the corresponding countermeasure, and has effectively solved this issue.
