/Operation and installation of drop-out fuses
When operating drop-out fuses, due to the single-phase operation using an insulating rod, operation with load is not allowed. . In practice, you will find that when the first phase is mistakenly opened under load, most situations are similar to disconnecting a parallel circuit or loop, and the disconnection voltage is low, so no strong arc will occur. When the second phase is pulled open with load, since the fracture voltage is line voltage, its fracture voltage is relatively high, so a strong arc will occur, which may cause arc short circuits in adjacent phases, threatening the safety of people and electrical equipment. . When the third phase is pulled open, because the circuit has tended to be open (no current or very small current), no arc will occur. Therefore, reasonable and correct operation of drop-out fuses is related to personal safety and circuit safety.
1. Preparation before operating the drop-out fuse Make preparations before operation, select qualified insulating tie rods with corresponding voltage levels, wear insulating gloves and insulating shoes to ensure safety
2. Operation verification Before operating, you must carefully check the name and number of the equipment to determine the correctness of the operation object
3. When operating, choose a position that is convenient for operation. Generally, it is appropriate to stand in front and below the current operating phase/drop-out fuse. , if the operation is on a pole tower, you should also fasten your seat belt
4. Operation Alignment During operation, align the movable contact of the drop-out fuse with its static contact to ensure the accuracy of the closing
5. When closing the in-close/drop-out fuse safely, you must be quick, decisive and accurate, but when closing it to the bottom, do not use too much force to prevent damage to the supporting insulator and other equipment
In addition In the daily operation of external/high-voltage fuses, the current characteristics of the fuse parts are unstable. As the operating environment and temperature change, it may cause coordination errors, override tripping and other phenomena. The quality of the fuse tube is poor, deformation and layering may occur, resulting in accidental drops for a long time. Poor contact between the upper and lower contacts is prone to occur during use, which can easily lead to contact heating, burning, and contact oxidation. Improper operation, use, and installation during operation and maintenance may lead to damage to its performance. Monitoring in this area should be improved.
