Embodiment Construction
[0034] like Figure 1-7As shown, the present invention includes an operating mechanism 5 and an arc extinguishing chamber assembly 4; the operating mechanism 5 operates the moving contacts in the arc extinguishing chamber assembly 4 to perform linear motion and rotation. The moving contact assembly 7 can linearly move and rotate along the axial direction of the moving contact 27 .
[0035] Preferably, the base 6 is also included; the operating structure and the arc extinguishing chamber assembly 4 are both arranged on the base 6 .
[0036] Preferably, a terminal block 3 is also included, and the terminal block 3 is rigidly connected to the base 6 through the insulating support 2; holes are left on the terminal block 3 for connecting main circuit wires and sensor wires.
[0037] Preferably, the operating mechanism 5 includes the moving contact assembly 7, the swing arm assembly 12, the second guide seat assembly 16, the cylinder seat 20, the linear guide rail seat 22 arranged ...
