Abstract

The invention discloses a switching device (10). The switching device (10) consists of at least two switching units, including a first switching unit (100), the first switching unit (100) comprises an insulating shell (101), a first power supply wire inlet end (110A), a second power supply wire inlet end (110B), a first power supply wire outlet end (120), a first static contact (150A), a second static contact (150B), and at least one moving contact (140) and at least one bistable permanent magnet electromagnetic driving device (200) which are arranged between the first static contact (150A) and the second static contact (150B), the moving contact (140) is bidirectionally driven by the bistable permanent magnet electromagnetic driving device (200) to be connected or disconnected with the first static contact (150A) or the second static contact (150B) respectively; and on the moving plane of the moving contact (140), the included angle between the driving shaft of the bistable permanent magnet electromagnetic driving device (200) and the moving contact (140) ranges from 30 degrees to 150 degrees.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a switch device. Background technique [0002] In the low-voltage and medium-high voltage electrical appliance industry, electromagnetic mechanisms are widely used in various switchgears due to their advantages of fast action speed, long life and low cost. The driving components of electromagnetic mechanisms are electromagnets. Electromagnets mainly have two typical mechanisms. , one is a long-term or short-term current excitation mechanism, and the other is a permanent magnet mechanism. [0003] like figure 1 As shown in the patent No. 201610916682.X, a commutation switch device is disclosed, which uses three permanent magnet mechanisms to respectively drive three sets of dynamic and static contacts to connect or break, and one of the permanent magnet mechanisms drives a set of dynamic and static contacts. On or off to realize the function of power commutation. The three p...
