(1) When the Switchgear Insulating Bushing main insulation withstands voltage, the primary side of the bushing is connected to the high voltage part of the AC withstand voltage device, and the flange and the end screen are grounded. When the end screen withstands voltage to ground, the bushing end screen is connected to the high voltage part of the withstand voltage device, the flange is grounded, and the end screen withstands voltage to ground strictly in accordance with the requirements of the product manual. The bushing withstand voltage of the equipment in operation is generally withstand voltage as a whole, according to the minimum test voltage of the combined equipment.
(2) When the single-component insulator withstands voltage, the high voltage end of the AC withstand voltage device is connected to one end of the insulator's hardware or flange, and the other end is grounded. When the multi-component insulator withstands voltage, the copper wire is wrapped around the insulator layer bonding and connected to the high voltage, and the two ends are grounded respectively.
