Abstract
The utility model relates to a 220kV zinc oxide arrester testing apparatus preventing high-voltage lead disassembly. In conventional construction, an elevating vehicle is required by lead disassembly in each routine experiment such that dangerous points are increased in each experiment and high-altitude falling hidden dangers are provided that may cause worker casualties. The 220kV zinc oxide arrester testing apparatus comprises a DC generator 1, a high-voltage microammeter 2, an operating case 7, a shielding wire 6, and an auxiliary device 5. The top of a top arrester 3 is connected with ground. The operating case is connected with the DC generator. The DC generator is connected with the high-voltage microammeter. The high-voltage microammeter is connected with a joint between the top arrester and a bottom arrester 4 through the shielding wire. The bottom arrester is connected with the auxiliary device through a shielding wire and then is connected with ground. The utility model is used for a 220kV zinc oxide arrester testing apparatus preventing high-voltage lead disassembly.
