Improve Melt Replacement Efficiency of High Voltage Fuse of 35 kV Voltage Transformer

RW10-3510.5 type 35 kV TV high voltage fuse has a high application rate in our company.Due to the structure and installation method of the high-voltage fuse, after the high-voltage fuse is burnt out, at least two people need to cooperate with each other to replace the melt tube in the process of replacing the melt tube.The whole replacement process is not only time-consuming, laborious and intensive, but also has an impact on high-quality power supply service due to power failure.To solve this problem, the method and existing problems of replacing the melt tube of the traditional rw10-3510.5 high voltage fuse are analyzed.Then the traditional 35 kV TV high-voltage fuse structure and installation method are improved by analyzing the causes.Finally, the improved high-voltage fuse is applied in 110 kV Dachaigou substation.After application, it is found that the improved high-voltage fuse can replace the melt tube without power failure.The operation process is effectively simplified, the labor intensity is reduced, and the melt replacement efficiency is improved.
