1. Daily maintenance and overhaul

Routine inspection and maintenance of high and low voltage switchgear assemblies during their daily operation. It mainly includes cleaning up dirt and adjusting its operating state. The maintenance cycle is usually a quarter.

2. Planned overhaul and maintenance

This kind of overhaul is mainly to disassemble the switch cabinet to carry out overhaul and overhaul the circuit breaker in the cabinet. And a preventive test of the switchgear equipment, secondary equipment maintenance and replacement, this maintenance cycle is usually one to two years.

3, strengthen.High and low voltage switchgearCondition-based maintenance

Real-time detection and control of high-voltage switchgear operating state, select the correct maintenance program. With the help of state maintenance to reduce power outage maintenance, to ensure the safe and efficient operation of the entire switch cabinet, improve the reliability of the entire power supply network.

Key Points of Maintenance of 2. High and Low Voltage Switchgear

1. Continuously strengthen the power cut-off management in maintenance

In overhaulHigh and low voltage switchgearIn the process, it is usually necessary to continuously stop power transmission operation, and the state of the switch cabinet is also changing during operation, which will affect the stability of the entire distribution network operation. At the same time, because of the large number of switch cabinets, the dispatching of distribution network is very difficult, so it should be divided according to the importance to ensure the smooth and efficient development of distribution network dispatching.

2. Ensure the safety of the maintenance process

During the maintenance of high and low voltage switchgear assembly, various relevant standards and specifications must be strictly observed to ensure safety first. Ensure the reasonable and scientific maintenance measures and technology, and clarify the responsibilities of relevant personnel to ensure the orderly development of maintenance.
