摘要
断路器是电力系统中的开关电器和保护电器。它不仅能关、合正常的负荷电流和空载电流,同时在线路和电气设备发生故障时,能可靠安全地切除故障电流,将故障线路和设备隔离,避免事故的扩大,使电力系统安全稳定地运行。就运行值班员发现运行中SW6—220型断路器液压机构压力降低,电气回路故障的原因进行分析,提出相应的处理意见,有利于提高变电运行人员对这类故障的处理判断能力,更好地搞好电力安全生产。
In the power system,breakers are used as switch devices and protection devices, For one thing , the breaker can break or close the load and light current regularly; For anther thing , once the lines and the devices have faults, breakers can remove the fault current reliably and safely, isolate the fault parts, avoid the expansion and keep the system working order, After analysing the pressure reduee of hydraulic pressure organ and the fault of eleetieal circuit on the SW6 - 220 style breaker, the thesis gives the slove suggestions. It is proved that these ideas are good for not only improving the ability of faults ＇ judgement and management but also safe power produce.
