Abstract

The invention discloses a transformer substation. The transformer substation comprises a high-voltage room, a transformer room and a low-voltage room, wherein a disconnecting switch, a lightning arrester and a high-voltage binding post are arranged in the high-voltage room, the disconnecting switch and the lightning arrester are connected with an external high-voltage cable, the high-voltage binding post is used for being electrically connected with the transformer room, the lightning arrester is arranged on a connecting cable between an outgoing post of the disconnecting switch and the high-voltage binding post and comprises an insulating puncturing cable clamp and a zinc oxide arrester body, the insulating puncturing cable clamp is provided with two cable clamping holes, and the zinc oxide arrester body is electrically connected with the insulating puncturing cable clamp. The electrical performance of the transformer substation is more stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a substation. Background technique [0002] Box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme. It is about high-voltage power receiving, transformer step-down, low-voltage distribution Electricity and other functions are organically combined and installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box, mechanical and electrical integration, fully enclosed operation, especially It is suitable for the construction and transformation of urban network, and it is a brand-new substation rising after the civil substation. The substation replaces the original civil...
