Wind power busbar

Abstract

The invention relates to a wind power busbar. Phase conductors are installed in the inner cavity of a shell formed by side plates and cover plates; the sections of the busbars are connected with one another through connectors; one pair of vertical side plates are clamped onto the inner sides of limiting ribs at two sides of one pair of horizontal cover plates, so that the shell can be formed; fixing blocks are fixed at the inner sides of the cover plates; the phase conductors are limited and fixed in the grooves of the two fixing blocks at the inner sides of the upper cover plate and the lowercover plate; the edges of the upper sides and lower sides of the side plates are provided with inwards-protruding steps which are clamped between the fixing blocks and the limiting rids of the coverplates; center positions of the upper fixing block and the lower fixing block, which are located between adjacent phase conductors, are connected together through bolts; the bolts are provided with insulating sleeves; the side plates are fixedly connected with the cover plates through threaded holes in grooves formed through the steps and through holes formed at corresponding positions of the limiting ribs of the cover plates; heat dissipation grooves are adopted, so that the contact area of the shell and the air is increased, and therefore, heat can be timely and effectively transmitted and dissipated; the seismic performance of the busbar is strong; the safety coefficient of the busbar system is high; and the load current of the busbar is large.

Description

technical field [0001] The invention relates to a wind power busbar, which is specifically applied in the technical field of busway manufacturing technology for power transmission systems in the wind power generation industry. Background technique [0002] The wind energy resources are huge, and the rapid development and broad prospects of wind power industry technology have brought huge market demand for bus duct products. Wind power bus duct products are an indispensable power supply system for wind power generators. Busway products generally adopt the form of heat sink structure installed on the side plate of the busbar. The installation gap between the heat sink and the side plate and the contact resistance hinder the transfer and distribution of heat. The heat dissipation efficiency is low, and the temperature of the busbar system rises, which also increases The user's use cost; the wind tower of the wind power generation unit is a super high building, and the strong wi...

[0002] The wind energy resources are huge, and the rapid development and broad prospects of wind power industry technology have brought huge market demand for busway products. Wind power busway products are an indispensable power supply system for wind power generators. Busway products generally adopt the form of heat sink structure installed on the side plate of the busbar. The installation gap between the heat sink and the side plate and the contact resistance hinder the transfer and distribution of heat, the heat dissipation efficiency is low, the temperature of the busbar system rises, and it also increases The user's use cost; the wind tower of the wind power generation unit is a super high building, and the strong wind causes the wind tower to swing and the frequency is very large. The wind power bus needs strong anti-seismic performance, and the dense insulation structure is adopted, and the anti-seismic performance cannot meet the requirements of wind power generation
