Abstract

The invention relates to a component structure of wind-powered electricity generation equipment, particularly to a converter of the wind-powered electricity generation equipment, which is connected between a wind-powered generator and an electric network. The converter comprises a cabinet body. The inner part of the cavity body is divided into five parallel chambers by vertical baffle plates; the front chamber is a first chamber positioned on the generator side; the back chamber is a fifth chamber positioned on the electric network side; a second chamber, a third chamber and a fourth chamber are sequentially arranged between the first chamber and the fifth chamber; a motor side circuit breaker is installed in the first chamber; three generator side half-bridge power units are arranged in the second chamber from top to bottom; three network side half-bridge power units are arranged in the third chamber from top to bottom; and an LCL filter is arranged in the fourth chamber and a network side circuit breaker is arranged in the fifth chamber. The converter has the advantages of compact structure, small space occupation, convenient installation in a wind-powered electricity generation tower barrel, more reasonable layout formation of each part and convenient distribution of internal wires and heat radiation pipelines.

Description

Converter cabinet for wind-powered electricity generation
Technical field
The present invention relates to a kind of modular construction of wind power plant, specifically is a kind of converter cabinet for wind-powered electricity generation that is used for being connected between wind-driven generator and the electrical network.
Background technology
Current transformer in wind power plant is to be connected being used between generator and the electrical network electric energy that wind power generation produces is carried out conversion, so that its equipment that satisfies the requirement of electric power conveying and output to electrical network.Current transformer is made up of function elements such as motor side circuit breaker, motor side half-bridge power unit, grid side half-bridge power unit, LCL filters usually, in the traditional structure, each component layouts is unreasonable, space hold is bigger, be unfavorable for the arrangement of back panel wiring and heat abstractor, be difficult to adapt to the installation requirement in the wind power tower drum.
Summary of the invention
Technical problem to be solved by this invention is that a kind of compact conformation, manufacturing and converter cabinet for wind-powered electricity generation easy for installation, rationally distributed, that be convenient to back panel wiring and heat radiation are provided.
Converter cabinet for wind-powered electricity generation of the present invention includes a cabinet, cabinet inside is divided into side by side five chambers by the dividing plate of holding up, chamber foremost is first chamber that is positioned at the generating pusher side, the chamber of rearmost end is the 5th chamber that is positioned at grid side, is followed successively by second chamber, the 3rd chamber and the 4th chamber between first chamber to the, five chambers; In described first chamber motor side circuit breaker is installed, be arranged with three pusher side half-bridge power units in second chamber from top to bottom, be arranged with three net side half-bridge power units in the 3rd chamber from top to bottom, be mounted with the LCL filter that constitutes by reactor and electric capacity in the 4th chamber, the 5th chamber top is mounted with net side circuit breaker, and the 5th chamber bottom is mounted with and is used for device in the cabinet is carried out the communication module of remote monitoring.
Be respectively arranged with the water inlet manifold and the outfall sewer that enter and reflux for cooling water of being used for of crossing over each chamber in the top of whole cabinet and bottom, water inlet manifold and outfall sewer respectively by in branch line and each chamber accordingly water-cooling apparatus be connected.
Compact conformation of the present invention, take up room for a short time, made things convenient for the installation in wind power tower drum; Particularly pusher side half-bridge power unit and the adjacent setting of net side half-bridge power unit, more reasonable with the layout formation of other devices, be convenient to arranging exhibits of back panel wiring and heat dissipation pipeline.
Description of drawings
Fig. 1 is a structural representation of the present invention.
