Abstract
Shenhua Yili Energy Co., Ltd. 6 kV factory busbar voltage transformer neutral point breakdown fuse (JBO) on the low voltage side under normal operating voltage was broke down, lead to 6 kV factory busbar voltage transformer secondary side circuit breaker short circuit trip. Through analysis, because the system ferroresonance overvoltage caused JBO was broken down, pointed out that the currently used JBO under the rated working voltage was broken down might cause a series of safety problems. Based on the system operation mode, put forward with the modified product, namely the electronic breakdown fuse (NYD-JBO) alternative JBO suggestion.关键词
