Problems solved by technology

At present, the 20kV line is put into operation, and the number of newly installed OSM circuit breakers continues to increase. However, due to the small contact area between the internal thread of the OSM circuit breaker terminal and the copper-aluminum joint, the contact is unreliable or even inaccessible. Very difficult, seriously affecting safe work and production and power supply reliability

Abstract

The invention discloses an OSM-type circuit breaker contact fitting. The fitting comprises a wire clamping module and a wiring module, wherein the wire clamping module and the wiring module are manufactured integrally; the wire clamping module is composed of two wire clamping plates; one ends of the two separated wire clamping plates are integrally manufactured to become a merged end, and the other ends of the two separated wire clamping plates are separated from each other in a is suspension manner to become separated ends; a first screw hole is formed in the merged end; and a second screw hole and a third screw hole are respectively formed in the wiring module. According to the OSM-type circuit breaker contact fitting provided by the invention, each wire clamping plate can provide constant contact pressure, and has high transition ability while low contact resistance is kept. The OSM-type circuit breaker contact fitting is simple in structure and convenient to install and maintain and can improve the work efficiency greatly.

Description

[0001] technical field [0002] The invention relates to a contact fitting for an OSM circuit breaker. [0003] Background technique [0004] With the continuous development of my country's economy, people have higher and higher requirements for power supply reliability and power quality. According to statistics, power lines and equipment joint failures account for more than 50% of power accidents. At present, the 20kV line is put into operation, and the number of newly installed OSM circuit breakers continues to increase. However, due to the small contact area between the internal thread of the OSM circuit breaker terminal and the copper-aluminum joint, the contact is unreliable or even inaccessible. Very difficult, seriously affecting safe work production and power supply reliability. [0005] Contents of the invention [0006] In order to solve the above problems, the object of the present invention is to provide a contact fitting for an OSM circuit breaker, the spli...
