Converting device of positive and negative electrodes of rectifier

Abstract

The invention discloses a converting device of positive and negative electrodes of a rectifier, comprising a positive electrode and a negative electrode of the rectifier and a machine frame; the machine frame is fixedly provided with two static contact plates at interval; two sides of each of the static contact plates are provided with movable contact plates; each of the movable contact plates isinstalled on the machine through a reciprocating driving device capable of driving the movable contact plates to contact or separate from the corresponding static plates; two movable contact plates on the same side of the two static contact plates are connected with each other by a flexible conductor and are respectively connected with the positive electrode and the negative electrode; and the two static contact plates are respectively used as two output electrodes or respectively connected with two output electrodes on the machine frame. Through compressing of the driving device disclosed bythe invention, the movable contact plates are contacted with the static contact plates more tightly so as to ensure that the contact points contact with each other by face and improve the conductivity between the movable contact plates and the static contact plates; the contact or separation between the movable contact plates and the static contact plates does not have abrasion; and the faults such as bad contact, switch burning and the like caused by the abrasion of knife switches for acting for a long time are avoided.

Description

technical field [0001] The invention relates to the technical field of rectifiers, in particular to a conversion device for a positive electrode and a negative electrode of a rectifier. Background technique [0002] A rectifier is a device that converts alternating current to direct current. In the actual production process, the polarity of the output electrode needs to be converted. The conversion of the positive electrode and the negative electrode of the traditional rectifier is generally performed by a switch knife. However, especially for some high-current rectifiers, the contact surfaces cannot be completely contacted, and the contacts are mostly line contacts, or even point contacts. And the switch knife is often opened and closed and easily worn. It can be seen that the working performance of the switch knife is very unreliable as the switching device of the electrode.
