Circuit Breaker Failure to Operate or Maloperation: Check the energy storage mechanism, closing/tripping coils, auxiliary switches, and secondary circuits. High-Voltage Fuse Blown: Measure voltage across the fuse terminals; inspect busbar joints, cable terminations, and. If an abnormality occurs in PT, it may cause an explosion fault of the PT, which will have a certain impact on the safe operation of the power system. This paper combines the actual production, in the dispatcher simulation training system (DTS) to set up a PT body and PT knife gate fault, the PT. In our power plant 10kv busbar pt feeder has interlock with incoming cb of busbar. The voltage of the 10kV bus fluctuates between high and low, and the culprit is actually the PT cabinet fuse that is constantly on and off! - Minrong Electric Group Co. The focus is on the failures and solutions of 10kV circuit breakers (vacuum, sulfur hexafluoride), disconnectors, busbars, transformers, transformers, cables and arresters. Engineering and technical personnel can refer to this article to analyze and process the accidents of high-voltage electrical.
