What are the precautions for maintenance of drop-out fuses

Drop-out fuses are commonly used in power systems. The function of European-style cable connectors is that when the transmission circuit is abnormal, such as a short circuit or current and voltage overload, the equipment automatically runs and quickly cuts off the faulty circuit, effectively protecting the safety of the entire power system. The drop-out fuse has a simple structure. Due to the requirements of outdoor working conditions, the internal electrical components are resistant to temperature and corrosion, and the exterior can be made of insulating materials to avoid the risk of electric shock during maintenance. It has the characteristics of low cost, easy operation, stable operation and so on.

Drop-out fuses and European-style cable joints will inevitably have problems after working for a long time. We must regularly check and repair them to reduce their failure rate and extend their service life. Drop-out fuse live electrical equipment, we must pay special attention to safety when we check and repair, and operate according to specifications.

The precautions for maintenance are described below. European cable connector

a. When performing equipment maintenance, the operator must wear insulated gloves, insulated boots, and goggles. Use qualified insulated rods that match the voltage level to operate. Operation is prohibited under lightning or heavy rain.

b. When carrying out the opening experiment, you must follow the sequence in order, firstly pull off the middle phase, then pull the left phase, and finally the right phase. There is a reason for this operation. The opening of the switch will generate an arc and cause a short circuit. We start from the intermediate phase with the smallest arc, which is not easy to cause a large-scale arc phenomenon, and has a relatively small impact on the circuit wires.

c. After the overhaul is completed, pay special attention to closing. The sequence is opposite to the opening direction, and must be carried out in strict accordance with the sequence to avoid safety accidents.
