Connecting structure for rectifier assembly

Abstract

Disclosed is a connecting structure for a rectifier assembly. The connecting structure comprises a first copper bar, a bolt, a first pressure plate, a disc spring, a second pressure plate, an insulating plate, an insulating sleeve, a diode and a second copper bar, wherein the first copper bar and the second copper bar contact each other via the diode to conduct electricity and are fixed by the bolt; and the bolt is adjusted till the two ends of the disc spring contact with the first pressure plate and the second pressure plate respectively. The flexible connection of the rectifier structure ischanged into a combination of hard and elastic connections, so that a sufficient space for operation can be provided under special circumstances, the safety factor is improved and the service life isprolonged.

Description

technical field [0001] The invention relates to the technical field of electrification, in particular to a connection structure of a rectification assembly. Background technique [0002] The current transmission of the three-phase rectifier transformer and the vibration and noise caused by the high temperature and high pressure process in the transformation process have an important impact on the service life of the transformer to a large extent. For example, when used in the field of welding, the welding process is a process of intermittent high-current continuous impact, so the influence of temperature, pressure, strength and impact current is further amplified, and under the premise of frequent energized welding, under the action of high current, the entire The loop generates a strong magnetic field, which leads to frequent vibrations of the annealed copper strip in its connection structure, which affects the structural strength and service life.
