Embodiment Construction
[0025] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0026] In the existing technology, the contact design of the traditional direct-acting plug-in grounding switch still lacks the consideration of the influence of the magnetic field of the electrode contact gap on the pre-breakdown arc, and the magnetic blowing effect of the magnetic field has not been successfully applied to the grounding switch. In terms of closing operation, it is still difficult for the grounding switch to successfully close the short-circuit current.
[0027] The inventor of the present application applied the magnetic blowing effect of the magnetic field on the arc to the in-line grounding switch for the first time. Through the horizontal magnetic blow effect or longitudi...
