Operation and Maintenance

Check the lead wire of the arrester and the grounding down conductor. There are burn marks and broken strands, and whether the discharge recorder burns through this aspect. It is most easy to find the invisible defect of the arrester; check whether the seal at the upper end of the arrester is good, and the seal of the arrester will be bad. If the water entering the water is easy to cause an accident, check whether the cement joint between the porcelain sleeve and the flange is tight. Install a waterproof cover on the lead of the 10 kV valve arrester to prevent rainwater from penetrating; check the arrester and the protected electric Whether the electrical distance between the equipment meets the requirements, the arrester should be as close as possible to the protected electrical equipment. The arrester should check the operation of the recorder after the thunderstorm. Check the leakage current. If the power frequency discharge voltage is greater than or less than the standard value, it should be repaired. And test; when the discharge recorder has too many movements, it should be repaired; there is crack in the porcelain sleeve and cement joint; when the flange and rubber mat are off, it should be repaired.
