Things We Need To Pay Attention To When Operating The Drop-out Fuse
Things we need to pay attention to when operating drop out fuse price
Nowadays, it is widely used in the market. After continuous research and application of the operation of drop out fuse set, people have found that when a three-phase load cuts off one phase, the break voltage will be slightly lower and the arc generated will be smaller. But when you cut off two phases, the break voltage will be slightly higher, and a very strong arc will appear when the circuit is cut off, and it is easy to cause a short circuit in the adjacent phase.
The usual drop out fuse unit does not have an arc extinguishing device. Therefore, when the transformer stops supplying power, if you do not want to have an accident of arc burns, you must avoid pulling the switch with load. In addition, in order to avoid operating errors, when biting the money to pull drop out type fuse, you must check whether the low-voltage switch is in the disconnected position.
For the safety of operators when operating dropout fuse of transformer, it is important to pay attention to the following: 1. When pulling the product, the voltage level must be appropriate. The insulating rods that have passed the test must all be insulated, and the shoes, gloves and hats must be insulated. You must stand on a dry wooden platform and have someone monitor to ensure safety. 2. There should be no impact when pulling and closing expulsion drop out fuse. Do not use too much force during the cooperative operation to avoid damaging fuse drop out. The opening and closing must also be in place. The operation process should be slow, then fast, then slow, and then slow. The fast one is to prevent the electric arc from causing electrical terminal failure and burning the contacts. The slow one is because of the impact of the qualified operation, which causes damage to ht drop out fuse. 3. Under normal circumstances, the order in which the distribution transformer stops supplying power is to open the low-voltage switch on the load side first and then the switch on the power supply side. This is generally the case. I hope that every operator will pay attention to his or her own safety during operation.
