Abstract

The invention discloses a special floating type static contact assembly device structure which comprises a main static contact assembly, a clip-shaped piece, a floating type arc striking static contact assembly, clip-shaped piece fixing screws, a connecting screw, a limiting shaft, a positioning shaft, a torsion spring, limiting screws and an arc striking sheet. The floating type arc striking static contact assembly assembles the limiting shaft, the positioning shaft and the torsion spring into an assembly through the clip-shaped piece, the assembly is fixed to the main static contact assemblythrough the clip-shaped piece fixing screws and the limiting screws, a copper braided wire on the floating type arc striking static contact assembly is fixed to the main static contact assembly through the connecting screw, and an equipotential is formed. A kidney-shaped hole is formed in the clip-shaped piece, the floating type arc striking static contact assembly floats up and down in the kidney-shaped hole, the overtravel of the floating type arc striking static contact assembly is increased, arc striking of the floating type arc striking static contact assembly is facilitated in the switching-on or switching-off process, and the switching-on or switching-off capacity is improved. By adopting the structure provided by the invention, the switching-on or switching-off capability can be improved, and the safety of a circuit is protected, so that the safety performance of a product is improved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a special floating static contact assembly device structure. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions, and can close, carry and break current under abnormal circuit conditions within a specified time, and is widely used in various fields . A circuit breaker is generally composed of a contact system, an arc extinguishing system, an operating mechanism, a trip unit, and a casing. The existing low-voltage circuit breaker may easily cause a large electric repulsion force due to the direction of the current, which is not conducive to the contact carrying a large load. The short-time withstand current or the short-time withstand current index is low. Especially when a circuit breaker with current limiting function produces a short circuit, its dynamic and static contacts will...
