Strategies for Ensuring Long-term Reliable Operation of Fixed Switchgear

Fixed switchgear is an indispensable core component in power systems, and its operational stability is directly related to the safety and reliability of the entire power distribution system. To ensure long-term efficient operation of switchgear, scientific maintenance, precise fault diagnosis, and professional technical support are crucial.

I. Maintenance Points for Low-Voltage Fixed Switchgear

1. Regular Cleaning and Dust Removal

• Cleaning Cycle: It is recommended to conduct a comprehensive cleaning every quarter.

• Cleaning Method: Use dry compressed air to blow away dust inside the equipment, or use a soft, lint-free dry cloth to wipe key components such as busbars, insulators, and circuit breaker surfaces. Avoid using water-based or corrosive cleaners to prevent damage to the equipment.

2. Electrical Connection Tightening and Inspection

• Inspection Focus: Busbar connections, circuit breaker terminals, grounding system connections, etc.

• Operational Requirements: Use professional torque tools to tighten bolts and connectors, ensuring the fastening force meets design specifications. Also, check for oxidation or corrosion at connection points and address or replace them as necessary.

3. Temperature Monitoring and Ventilation Management

• Monitoring Means: It is recommended to install online temperature monitoring devices to monitor temperature changes in key components (such as busbars and circuit breaker contacts) in real-time.

• Ventilation Management: Regularly check whether the switchgear's ventilation openings and cooling devices are unobstructed. Clean the vents or replace filters as necessary to ensure heat is effectively dissipated from the cabinet.

II. Causes and Solutions for Common Faults

1. Local Overheating of Equipment

• Check and tighten all electrical connections to ensure good contact;

• Redistribute loads to avoid overloading a single circuit;

• Improve the ventilation conditions of the equipment's operating environment, and install auxiliary cooling devices if necessary.

• Loose electrical connections;

• Load exceeding rated capacity;

• Poor ventilation or high ambient temperature.

• Possible Causes:

• Solutions:

2. Decreased Insulation Performance

• Regularly clean the inside of the equipment and keep the environment dry;

• Install dehumidifiers or heaters in humid environments;

• Inspect insulation components for cracks, aging, or breakdowns, and replace damaged insulation materials promptly.

• Dust and moisture intrusion;

• Aging or damage of insulation materials.

• Possible Causes:
