Maintenance of breaker is carried out yearly under normal use and every six months under
abnormal use. The maintenance includes following procedures:
(1)再扣断路器,合、分断路器,在断路器合闸时用脱扣按钮使断路器脱扣,往复操作 5 次,断路器应
能可靠进行再扣、合、分、脱扣动作;
(2)清除断路器表面及连接处的灰尘(用清洁、干燥的抹布擦拭)
;
(3)清洁隔弧板,如必要则需要更换隔弧板;
(4)绝缘测试(见 7.1)
(5)检查所有连接情况,用砂布擦除氧化物,用可溶解剂清洁,拧紧螺栓和螺母;
(6)控制器整定值测试:应使用我公司的 NDM3E 专用测试仪器与断路器的 TEST 端口连接,检验各个设定
参数,以保证参数设定与旋钮指示一致;
(7)如果断路器还装有其它内、外部附件,应逐一检查各个附件,以确保其处于正常工作状态。
(按照 8 附件说明 详细内容进行测试)
(1)
Re-trip the breaker, close and open the breaker, use tripping button to trip the breaker
when it is closed;
repeat for 5 times to check that the breaker can reliably re-trip, open, close and trip.
(2)Clean dust on breaker surface and connections (wipe with clean and dry cloth).
(3)Clean the flash barrier; replace it if necessary.
(4)Carry out insulation test (see Section 7.1).
(5)Check condition of all connections. Wipe away oxidations with abrasive cloth and clean with
soluble agent
. Screw bolts and nuts tight.
(6)Test of controller setting values: use a tester specialized for NDM3E provided by Nader to
connect with TEST terminal of the breaker. Check setting of each parameter to ensure that
parameter setting is consistent with knob indication.
(7)If other internal or external accessories are installed in the breaker, check them one by
one to ensure they
are in normal working condition (carry out test according to Section 8: Detailed accessory
descriptions).
