Fault Analysis Experiment Of Vertical Fuse Disconnector Under High Load Operation

Under high load or abnormal current conditions, the temperature of one of the vertical fuse switch disconnector components soared by 49°C (to 76.8°C) within one minute. If disconnected in time, the heat buildup could lead to carbonization of the insulation and annealing of metal components. The nhrt40 vertical fuse switch disconnector component would continue to heat up, ultimately causing overheating and even fire risks.
