Embodiment
[0061] This embodiment provides a two-way propulsion isolating switch, such as Figure 2 to Figure 4 ,with Figure 9 As shown, it includes: a first contact arm 1, adapted to be electrically connected to a first contact a41, and having a first contact portion 11; a second contact arm 2, adapted to be electrically connected to a second contact a42, and having a first contact portion 11; Two contact parts 21, the first contact a41 and the second contact a42 are a pair of moving and stationary contacts opposite to each other; the driving mechanism is used to drive the first contact arm 1 to move along its axial direction, and then The first contact portion 11 is connected or disconnected from the external circuit, and the second contact arm 2 is driven to move along its axial direction, so that the second contact portion 21 is connected or disconnected from the external circuit.
[0062] When used in a high-voltage vacuum circuit breaker, the first contact a41 and the second cont...
