What are the maintenance precautions for drop-out fuses?
Drop-out fuses are commonly used in power systems. The function of European-style cable joints is that when an abnormality occurs in the transmission circuit, such as a short circuit or current and voltage overload, the equipment automatically operates and quickly cuts off the faulty circuit, effectively protecting the safety of the entire power system. Drop-out fuses have a simple structure. Due to the requirements of outdoor working conditions, the internal electrical components are temperature-resistant and corrosion-resistant, and the outside can be made of insulating materials to avoid the risk of electric shock during maintenance. It has the characteristics of low cost, easy operation and stable operation.
After long-term operation of drop-out fuses and European-style cable joints, problems will inevitably occur. We must inspect them regularly to reduce their failure rate and extend their service life. Drop-out fuses are used for live electrical equipment. When we perform maintenance, we must pay special attention to safety and operate according to specifications.
The following introduces maintenance precautions. European cable connector
a. When performing equipment maintenance, operators must wear insulating gloves, insulating boots, and goggles, and use qualified insulating rods that match the voltage level. Operation is prohibited in weather with lightning or heavy rain.
b. When performing the switching test, the order must be followed, first pulling off the middle phase, then the left phase, and finally the right phase. There is a reason for this operation. Pulling the switch will produce an arc and cause a short circuit. We start from the middle phase with the smallest arc, which will not easily cause a large-scale arc phenomenon and have a relatively small impact on the circuit wires.
c. After the maintenance is completed, special attention should be paid to closing the switch. The order is opposite to the direction of opening the gate, and must be strictly followed to avoid safety accidents.
