Maintenance methods for SF6 ring main unit

The scientific and reasonable maintenance tasks of SF6 ring main unit are indispensable. What are the methods used in the maintenance process of SF6 ring main unit? What is the actual effect of different maintenance methods for SF6 ring main unit? Next, let's get to know each other together.

1. The inspection needs to check that the SF6 ring main unit is operated 100 times under full load, and then the main circuit resistance of the load switch is checked for insulation level. If there are no other conditions, then the mechanical equipment load switch is operated 100 times under normal load conditions. If any other conditions are detected, the manufacturer must be immediately contacted and sent for maintenance.

2. To record the operation status of the SF6 ring main unit, it is necessary to record the status on time. However, it is not necessary to record the basic operating parameters and current status of the mechanical equipment, but rather to record the data information displayed by the SF6 gas pressure gauge in the inflation cabinet inside the SF6 ring main unit, Based on the SF6 gas condition curve displayed on the pressure gauge, it is possible to distinguish whether gas needs to be added or leaked. Under normal conditions, if there is no mechanical equipment damage or other reasons, it is basically impossible for SF6 gas in the inflation cabinet to have other drops or sudden situations within 15 years. The specific way to add gas is to pay attention to adding it on time to prevent interference with the operation of the SF6 ring main cabinet every 15 years.
