Abstract

The invention provides a self-opening / closing vacuum breaker device. The device comprises a main current input electrode, an excitation current input electrode, a vacuum chamber, an upper electrode column, a lower electrode column, an excitation current output electrode, a main current output electrode and an opening / closing control mechanism. The opening / closing control mechanism comprises an opening / closing mechanism and a control mechanism. The opening / closing mechanism is arranged between the upper electrode column and the lower electrode column. A control magnetic field is formed between the control mechanism and the opening / closing mechanism. The main current input electrode is connected with an outer end of the upper electrode column, and the main current output electrode is connected with an outer end of the lower electrode column. The excitation current input electrode and the excitation current output electrode are connected with the control mechanism. An inner end of the upper electrode column, an inner end of the lower electrode column and at least the opening / closing mechanism of the opening / closing control mechanism are all arranged inside the vacuum chamber. The device completely removes a complex external mechanical opening / closing mechanism system of a breaker in the prior art, and is simple and compact in structure, high in system integrated level, and quick and sensitive for using.

Description

technical field [0001] The present invention relates to the technical field of vacuum circuit breakers, in particular to a self-opening and closing vacuum circuit breaker device. Background technique [0002] Vacuum circuit breakers have the advantages of small size, light weight, suitable for frequent operations, and no maintenance for arc extinguishing, and are widely used in distribution networks.
