Operation And Installation Of High Voltage Drop-out Fuses

drop out fuse element Operation and Installation
Several methods have been summarized from practical experience for reference:

1. Preparation before operation: Make preparations before operation, select qualified insulating pull rods of corresponding voltage level, wear insulating gloves and insulating shoes to ensure safety;

2. Operation verification: Before operation, carefully check the equipment name and number to determine the correctness of the operation object;

3. Position during operation: Choose a position that is convenient for operation. Generally, it is advisable to stand in front of and below the current operating phase high voltage drop out fuse in transformer. If it is an operation drop out fuse price on the pole tower, you should also fasten your safety belt;

4. Operation alignment: During operation, align the drop out fuse set moving contact with its static contact to ensure drop out fuse unit. Accuracy of the closing position;

V. Fully safe closing: When closing the high voltage drop out type fuse, it needs to be quick, decisive and accurate, but when closing it to the bottom, do not use too much force to prevent damage to the dropout fuse of transformer supporting insulators and other equipment;

In addition: In the daily operation of the high voltage expulsion drop out fuse, the current characteristics of the fuse are unstable, and with the changes in the operating environment and temperature, it causes coordination errors and fuse drop out over-level tripping; the quality of the fuse tube is poor, and it deforms and delaminates, resulting in accidental falling; long-term use of ht drop out fuse is prone to poor contact between the upper and lower contacts, which is easy to cause contact heating, burning and contact oxidation; due to improper operation, use and installation during operation and maintenance, its performance is damaged. Monitoring in this regard should be improved.
