What should be paid attention to in the spring inspection of substation?

First of all, spring is the rainy season, with frequent rainy and foggy weather and humid air, which is prone to secondary line failures and equipment pollution flashover. Therefore, in spring, each substation takes moisture-proof, seepage-proof, anti-pollution flashover and anti-condensation as a very important job. Therefore, as an electric power worker, the work at this time will be more arduous.

Secondly, the key points to note are as follows:

1. During the spring inspection of substations, the moistureproof equipment in the switch room, distribution room and outdoor terminal box of each substation shall be inspected in detail;

2. Carefully observe whether there is water condensation in the junction box and mechanism box of high-voltage equipment; Xiao Hang suggested that you should carefully check the faulty equipment and plug the loopholes and omissions in time. Polymer moisture-proof plugging agent (self-leveling, one-component, ready-to-use), leakage-proof plugging agent (live working, spraying, convenient and quick) and other moisture-proof plugging agents can be used for plugging;

3. Carefully check the dryness of various safety insulation appliances in the tool cabinet;

4. Check the cabinets in the control room and the walls, windows and ceilings of all rooms for water leakage;

5. Check the flood control channels inside and outside the substation to ensure smooth drainage in rainy season;

6. Improve the quality and quantity of special weather patrol in substations;

7. Conduct professional patrol with infrared thermometer, keep in touch with the meteorological department, pay close attention to the possible impact of bad weather on the power grid, take timely measures, and earnestly implement various preventive work.
