Routine maintenance and repair of high-voltage fuses are crucial. The following are the aspects that need attention:

1. Daily maintenance

1.Appearance inspection

Regularly check the appearance of the high-voltage fuse to see if there are cracks, damage, deformation, etc. If any abnormal appearance is found, the fuse should be replaced in time to ensure its normal operation.

Check whether the fuse shell is clean. If there is dust, dirt, etc., clean it in time to avoid affecting the heat dissipation and insulation performance.

2.Connection fastening

Check whether the connection between the fuse and the circuit is tight and make sure the contact is good. Loose connections may increase contact resistance, causing heating or even fuse failure.

Tighten the connection parts regularly and use appropriate tools to tighten according to the specified torque to prevent loosening.

3.temperature monitoring

Use infrared thermometer and other equipment to monitor the temperature of the running high-voltage fuse to observe whether its temperature is within the normal range.

If an abnormal increase in temperature is found, the cause should be identified in time, which may be overload, poor contact or fault of the fuse itself, etc., and corresponding measures should be taken to deal with it.

4.environmental inspection

Ensure that the high-voltage fuse is installed in a dry and well-ventilated environment to avoid moisture, rain, etc. A humid environment may reduce the insulation performance of the fuse and increase the risk of failure.

Check whether there are flammable and explosive items around, and keep a safe distance to prevent accidents such as fires.

2.Maintenance precautions

1.security measures

Before performing maintenance on high-voltage fuses, safety operating procedures must be strictly followed and safety protection measures must be taken.

Power outage, power inspection, and grounding are conducted to ensure the personal safety of maintenance personnel. Set warning signs to prevent others from misoperation.

2.Tool preparation

Prepare special maintenance tools, such as insulating gloves, insulating wrenches, multimeters, etc. Make sure the insulation performance of the tool is good to prevent electric shock accidents.

3.Disassembly and installation

When removing a high-voltage fuse, be careful to avoid damaging the fuse and surrounding equipment. Disassemble in the correct order and record the location and connection of each component.

When installing a new fuse, make sure the model and specifications are consistent with the original fuse. Install the melt correctly so that it makes good contact with the contacts.

4.Testing and Debugging

After installation is complete, perform necessary testing and debugging. Use tools such as a multimeter to check the continuity of the fuse to ensure it is working properly.

Conduct a power-on test on the circuit and observe whether the fuse blows within the specified current range to verify its protective performance.

5.Records and reporting

Keep detailed records of the maintenance and repair of high-voltage fuses, including inspection dates, problems found, and treatment methods.

Write maintenance reports and report maintenance results to superior leaders or relevant departments to provide a basis for equipment operation and management.

In short, the daily maintenance and repair of high-voltage fuses need to be careful and strict, and safety operating procedures must be strictly followed to ensure the normal operation of the equipment and the safety of personnel.
