A wind energy two-piece side-mounted high-protection busbar

Abstract

The invention brings forward a wind energy two-sheet side-installed high protection bus comprising a bus main body which comprises a main section bar and a side section bar. The main section bar comprises a main vertical plate, an upper web plate and a lower web plate. The upper web plate and the lower web plate are provided with main clamp connection plates and rigid structures. The side section bar comprises a side vertical plate, an upper transverse plate and a lower transverse plate. The upper transverse plate and the lower transverse plate are provided with side clamp connection plates. The main section bar is in clamp connection with the side section bar, and is in riveted joint through a nonporous rivet. The wind energy two-sheet side-installed high protection bus of the invention is simple in structure and reasonable in design. Compared with a traditional bus, the main section bar equivalently integrates three section bars which are an upper base plate, a lower base plate and a left side plate of the traditional bus. The main section bar is in clamp connection with the side section bar; nonporous riveted joint is employed; the riveted joint process does not need overturn; the technology is more simplified; the production efficiency is raised and the reliability and accuracy of bus installation positioning are improved; water proofing and sand prevention performance are improved; the arrangement of an elastic rubber pad can effectively eliminate bus shaking caused by corona; and the safety performance of the bus is raised.

Description

technical field [0001] The invention relates to the technical field of wind energy transmission and distribution, in particular to a wind energy two-piece side-mounted high-protection busbar. Background technique [0002] Wind power generation is a low-carbon new energy generation that uses natural wind energy to generate electricity. The two-piece side-mounted high-protection busbar system dedicated to wind power generation is widely used in primary transmission sites where the rated insulation voltage of 5MW and below wind power generation is less than 1000v. It mainly carries the primary power output task of wind power generation. It is installed on the inner wall of the wind turbine tower. It belongs to the shaft bus bar installed vertically; at the same time, it can also be used for horizontal layout inside and around civil workshops, horizontal and vertical layout inside high-rise buildings, between transformers and power distribution cabinets in substations, and betwe...
