Problems solved by technology

Traditional direct-moving electrodes, in the case of small currents, especially when breaking inductive small currents, are prone to interception and overvoltage, and are easy to damage electrical loads. It is necessary to install overvoltage limiting devices or use low overvoltage contact materials; Under the condition of high current, the shrinkage of the arc is intensified, which makes the erosion of the electrode serious, which restricts the improvement of the breaking capacity of the vacuum circuit breaker

Abstract

The invention relates to the technical field of electric appliance switches, and specifically relates to an electrode structure with rotation on-off for a vacuum circuit breaker. The control capability of arc can be improved, the on-off performance of the vacuum circuit breaker is enhanced, and the rotation motion of the electrode is realized in an on-off process. The electrode structure comprises a static electrode assembly and a rotation movable electrode assembly, a movable electrode of the rotation movable electrode assembly and a static electrode of the static electrode assembly are switched on or switched off through relative motion, and the relative motion refers to linear motion and rotation motion at the same time.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to an electrode structure for rotary breaking of a vacuum circuit breaker. Background technique [0002] During the breaking process of the vacuum circuit breaker, the operating mechanism outside the vacuum interrupter transmits the driving force to the vacuum interrupter through the pull rod and the driving insulator, that is, the bellows and the moving conductive rod drive the moving electrode to realize the rapid opening action. During the opening process, an arc will be generated between the two electrodes. Usually, a transverse magnetic field or a longitudinal magnetic field is generated between the two electrodes to control the vacuum arc and accelerate the extinguishment of the arc. The electrode structures in the prior art include flat butt contact, transverse magnetic field contact, longitudinal magnetic field contact and other types. This kind of straight-line...
