| Abstract: | Problems existing in malfunction protection during operation were analyzed, there are two problems in it, one is that one - phase re - switching might not work when the outlet breaker of malfunction protection instantaneous trip circuit is spnmg, the other is that malfunction might be caused when malfunction protection outlet connects to TJP of phase separated box. Improving measures were presented focusing on the problems mentioned above, and tests were carried out on site, the results showed that the measures are feasible. |
