High-voltage bushing for 35KV transmission

Abstract

The invention relates to the technical field of high-voltage conveying, in particular to a high-voltage bushing for 35KV transmission. The bushing comprises a sleeve body and a central conductor, oneend of the sleeve body is provided with a high-potential connecting flange, the other end of the sleeve body is provided with a low-potential connecting flange, the central conductor is arranged in the sleeve body, the bushing further comprises a first shielding cylinder and a second shielding cylinder, the first shielding cylinder sleeves the central conductor, and the second shielding cylinder sleeves the first shielding cylinder. The central conductor positioned in the sleeve body is completely positioned in the first shielding cylinder; the first shielding cylinder is completely located inthe second shielding cylinder, the first shielding cylinder and the second shielding cylinder form two radiation protection layers, the radiation protection effect of the high-voltage bushing can besignificantly improved, the influence of the high-voltage central conductor on the body health of an electrical operator is reduced, and the first shielding cylinder and the second shielding cylinderare simple in structure and convenient to install, and the popularization and promotion are facilitated.

Description

technical field [0001] The invention relates to the technical field of high-voltage transmission, in particular to a high-voltage bushing for 35KV transmission. Background technique [0002] Because the loss of high-voltage transmission electric energy is small, the transmission of electric energy in my country basically adopts high-voltage transmission. At present, during 35KV high-voltage transmission, when the current-carrying conductor needs to pass through a metal box or wall with a different potential, a high-voltage bushing needs to be used. The existing high-voltage bushing includes a sleeve body and a central conductor. One end of the sleeve body is provided with a High potential connection flange, the other end is provided with low potential connection flange, the center conductor is set inside the casing, and one end of the center conductor is connected to the high potential connection flange, and the other end is set through the low potential connection flange, a...
