Abstract
The invention relates to a test method for a high-voltage lead uncleared test device of a 220-kV zinc oxide arrester. According to a traditional arrester with the voltage class equal to or higher than 220 kV, a connection line is high, a high-voltage lead is thick, and a lift truck is needed for lead clearing in a routing test each time; as a result, the lead clearing workload of clearing in the routing test each time is large, long time is consumed, risk points are increased, and the situation that casualties of workers are caused by the high-altitude falling hidden danger exists. The high-voltage lead uncleared test device of the 220-kV zinc oxide arrester comprises a direct-current generator (1), a high-voltage microammeter (2), an operation box (7), a shielded line (6) and an auxiliary device (5). The upper end of an upper arrester section (3) is grounded. The operation box is connected with the direct-current generator. The direct-current generator is connected with the high-voltage microammeter. The high-voltage microammeter is connected with the joint between the upper arrester section and a lower arrester section (4) through the shielded line. The lower arrester section is connected with the auxiliary device through the shielded line and then is grounded. The test method is applied to the high-voltage lead uncleared test device of the 220-kV zinc oxide arrester.
