电力机车辅助电路过电流继电器113安装在111转换开关后,曾多次因某种原因使111闸刀短路烧损,造成5~#柜起火。由于113装在111后,不能及时地跳开主断路器使事故缩小。为此我段从1983年开始,在每次定修时就将113过电流继电器改装在111转换开关前,具体接线如图1、图2所示。 Electric Locomotive Auxiliary Circuit Overcurrent relay 113 installed in the 111 switch, has repeatedly for some reason to 111 short circuit burn knife, causing 5 ~ # cabinet fire. As installed in 111 after 113, can not jump on the main circuit breaker in time to reduce the accident. To this end, I paragraph from 1983 onwards, in each repair will be over-current relay 113 converted in 111 before the switch, the specific connection shown in Figure 1, Figure 2.
