Embodiment 1
[0055] as Figure 1 As shown, the three-station isolated grounding switch comprises a housing 11, the housing 11 is provided with a moving support 12, the moving support 12 extends in a vertical direction, the upper end of the moving support 12 is fixed at the top of the housing 11, and the lower end of the moving support 12 is connected to the moving contacts 14. The housing is also provided with a grounding static contact 13 and an isolation static contact 15, the grounding static contact 13 is on the right side of the moving support 12, the isolation static contact 15 is below the moving support 12. Wherein, the moving contact 14 is rotated by an insulated torsion bar drive to achieve conductive contact with the isolated static contact 15 or the grounding static contact 13, thereby realizing the isolation and grounding function.
[0056] The moving contact 14 is inserted into the direction of the isolated static contact 15 as the left and right directions. as Figure 2 and Figur...
Embodiment 2
[0071] The difference between the present embodiment and Example 1 is that, in Example 1, the lead arc is a Z-shaped structure, and the arc segment is provided at the end of the lead arc sheet. In the present embodiment, the lead arc is a glyph structure, the arc segment is set in the middle position of the lead arc.
Embodiment 3
[0073] The difference between the present embodiment and Example 1 is that, in Example 1, the two vertical seats are provided with two lead arc plates, and the two lead arc pieces on the same vertical seat are arranged in the left and right directions. In the present embodiment, the two vertical seats are each provided with an arc piece.
