Connecting structure for high-voltage equipment of offshore booster station and mounting method of connecting structure

Abstract

The invention discloses a connecting structure for high-voltage equipment of an offshore booster station, and relates to the field of new energy and power systems. The structure comprises a main transformer inlet wire switch cabinet, a main transformer and GIS equipment. The main transformer inlet wire switch cabinet is connected with the main transformer; the GIS device extends into the main transformer chamber and is connected with the main transformer; a copper pipe bus comprises a copper pipe bus body and a terminal; and the terminal comprises a silicone rubber adapter and a bus terminal copper contact. The main transformer inlet wire switch cabinet is connected with the low-voltage side of the main transformer through the copper pipe bus, so that the length of a connecting conductor is shortened, the problems of too many fixing fittings, too large bending radius of a cable, difficulty in construction and the like during cable installation are solved, the probability of interphase short circuit of the low-voltage side of the main transformer can be reduced to a certain extent, and the service life of the main transformer is prolonged. the power transmission reliability is improved, and the electric energy loss is reduced. The invention further relates to a mounting method of the connecting structure for the high-voltage equipment of the offshore booster station.

Description

technical field [0001] The invention relates to the field of new energy and power systems, and more specifically relates to a connection structure for high-voltage equipment in an offshore step-up station. The invention also relates to an installation method of the high-voltage equipment connection structure of the offshore booster station. Background technique [0002] Due to the fact that the offshore booster station is far away from the coast and the weather conditions are poor, it has the characteristics of difficult maintenance and high maintenance costs. At the same time, as the "heart" of the offshore wind farm, it is the core of the power transmission of the wind farm. Reasonable selection of high-voltage equipment for the offshore booster station The connection method is of great significance to offshore wind farms and helps to reduce the risk of offshore wind farm construction. Therefore, in the selection of the upper incoming line, the reliability and ease of mai...

Problems solved by technology

At present, the traditional high-voltage equipment connection method of the offshore booster station uses a cable bridge connection structure, that is, the high-voltage side cable and the low-voltage side cable of the main transformer are fixed by erecting a fixed bracket, and the cable head is used to connect the high-voltage equipment of the offshore booster station. , the connection structure is not only too long for the incoming cable, but also has poor insulation, is not easy to overhaul, and has low reliability
