Power distribution cabinet for substation and integrated substation

Abstract

The invention relates to the technical field of transformers, in particular to a power distribution cabinet for a substation and an integrated substation. For the busbar, the rear side wall of the incoming line protection room is set on the rear side plate of the cabinet body. There is a heat dissipation port connected with the outside world on the rear side wall of the incoming line protection room. The partition between the incoming line protection room and the incoming and outgoing line room There is a busbar perforation for the incoming busbar to enter the incoming and outgoing line room, and a seal for sealing the incoming and outgoing line room is arranged in the busbar through hole. The heat generated by the part of the incoming line busbar in the incoming line protection room can be dissipated through the heat dissipation port. In addition, since the incoming line protection room is inside the cabinet, the heat in the cabinet can enter the incoming line protection room through heat transfer, and then dissipate through the heat dissipation port. Compared with the current power distribution cabinets that only dissipate heat through fans, the bus protection room provided on the power distribution cabinets of the present invention further improves the heat dissipation performance of the power distribution cabinets.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a power distribution cabinet for a substation and an integrated substation. Background technique [0002] Rural power grids have the characteristics of large seasonal load fluctuations and low average loads, which are prone to problems such as excessive reactive power of the grid and excessive ratio of transformer no-load loss to transmission capacity. The Chinese utility model patent with the authorized announcement number CN207530412U and the authorized announcement date of 2018.06.22 discloses a 10KV integrated pole-mounted transformer, including a bracket, a transformer and a JP cabinet. The transformer and the JP cabinet are arranged horizontally on the bracket. The JP cabinet That is, the power distribution cabinet. The transformer is equipped with a low-voltage outlet terminal and a high-voltage outlet terminal. The low-voltage outlet terminal is connected to a busbar...
