How to maintain the high-voltage ring main unit?

The maintenance tasks of the high-voltage ring main unit equipment must be paid attention to, so that the tasks of the ring main unit can be carried out more smoothly.

1. General inspection

After the ring main unit is run one hundred times with full load, the main circuit resistance of the load switch must be checked routinely for the first time. If there is no problem, the load switch of the machine equipment is normally operated one hundred times with load. If any problem is found after running 100 times, you should contact the manufacturer immediately and send it for repair. On the one hand, regularly check the switch mechanism and mechanical equipment control of the mechanical equipment after the high-voltage ring main unit runs for 1W without load. If the condition is not found for a long time, it means the test can end.

2. Record

Periodically record the running status of the ring main unit. The data information displayed by the SF6 gas pressure gauge in the high-pressure ring main unit charging cabinet must be recorded. According to the SF6 gas condition curve displayed by the pressure gauge, it is generally possible to distinguish whether the SF6 gas in the inflatable cabinet is full or leaking. As long as it is not damaged by mechanical equipment or other factors, there will be no reduction or abnormality within 15 years. Special attention is paid to periodic additions to prevent interfering with ring main unit operations.

3. Interval

The regular inspection of the high-voltage ring main unit should be based on the non-maintenance-free ring main unit. Generally speaking, the maintenance interval is not too long. However, due to different usage conditions, the interval for regular maintenance will vary. Generally speaking, the actual repair time recommended by the manufacturer is the repair time. Please adjust according to your own regional environment. If a situation is found, certain effective measures should be taken immediately to prevent the problem from causing interference to machines and equipment such as lines.

4. Relevant personnel

The control, maintenance and installation personnel of the ring main unit are all skilled personnel with professional knowledge. When there is a problem with mechanical equipment, these people will immediately identify the source to solve the problem, and do a good job based on professional knowledge. The installation and maintenance personnel should clarify the performance and service life of the ring main unit.
