Abstract
The invention discloses a current equalizing structure of a high-current rectifier bridge arm, comprising a left rectifying bridge arm and a right rectifying bridge arm, wherein the front sides and the right sides of the left rectifying bridge arm and the right rectifying bridge arm are respectively and fixedly connected with a plurality of connecting busbars from top to bottom, and one ends of the connecting busbars at the upper end and the lower end are respectively outwards bent. In the invention, one ends of the connecting busbars at the upper end and the lower end are respectively outwards bent, i.e. the lengths of the connecting busbars at the upper end and the lower end are increased, and the unbalanced condition of the whole rectifying bridge arm current is reduced, thereby a good current equalizing effect is achieved.
Description
Technical field
The present invention relates to a kind of equal flow structure of high-current rectifier brachium pontis.
Background technology
Generally speaking, the connection busbar of rectification brachium pontis is isometric, caused the asymmetry of brachium pontis structure, therefore, in the application scenario of big electric current, electric current in the brachium pontis between the element in parallel is very uneven, thereby makes subelement be in overload for a long time, directly influences the fail safe and the reliability of rectifier operation.In addition,, can also suitably reduce parts number in parallel, save cost by improvement to current stabilizing factor.
But for a long time, few people make quantitative analysis to the current imbalance reason of brachium pontis, just rest on the aspect of qualitative analysis.Thereby, be difficult to propose accurately, effectively to improve method.
Summary of the invention
The equal flow structure that the purpose of this invention is to provide a kind of high-current rectifier brachium pontis, the length of the connection busbar of brachium pontis is not wait, wherein the length of upper/lower terminal connection busbar is longer, the equal flow structure that improves.
Technical scheme of the present invention is as follows:
A kind of equal flow structure of high-current rectifier brachium pontis, include left and right rectification brachium pontis, it is characterized in that: the forward and backward face of described left and right rectification brachium pontis is fixedly connected with several from top to bottom respectively and connects busbar, and an end that wherein is positioned at the connection busbar of upper/lower terminal is distinguished outwardly-bent.
Beneficial effect of the present invention:
One end of the connection busbar of upper/lower terminal of the present invention is outwardly-bent respectively, and promptly the length of the connection busbar of upper/lower terminal increases, and the uneven situation of whole rectification brachium pontis electric current greatly reduces, and has reached good current-sharing effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Referring to Fig. 1, a kind of equal flow structure of high-current rectifier brachium pontis, include left and right rectification brachium pontis 1,2, the forward and backward face of left and right rectification brachium pontis 1,2 is fixedly connected with several from top to bottom respectively and connects busbar 3, and an end 4 that wherein is positioned at the connection busbar of upper/lower terminal is distinguished outwardly-bent.
