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...

Abstract

The invention provides a bidirectional-driving disconnector, comprising a first contact arm, a second contact arm and a driving mechanism, wherein the first contact arm is suitable to be connected with a first contact electrically; the second contact arm is suitable to be connected with a second contact electrically and has a second contact part; the first contact and the second contact are a pair of moving contact and fixed contact which are arranged oppositely; the driving mechanism is used for driving the first contact arm to move along the axial direction of the driving mechanism so as to enable the first contact part to be connected with or disconnected from an external circuit and also for driving the second contact arm to move along the axial direction of the driving mechanism so as to enable the second contact part to be connected with or disconnected from the external circuit. Compared with the prior art, the bidirectional-driving disconnector occupies less space, facilitates the miniaturization and compactness of equipment; since two obvious disconnection points occur when in a disconnected state, the bidirectional-driving disconnector, compared with a disconnector in the prior art, has the advantage of high safety performance.

Description

technical field [0001] The invention relates to the technical field of isolating switches for high-voltage vacuum circuit breakers, in particular to a bidirectional propulsion isolating switch. Background technique [0002] High-voltage vacuum circuit breakers are electrical equipment often used in high-voltage power distribution systems. They usually include a circuit breaker and an isolation switch. The function of the circuit breaker is to close the circuit and open the circuit, and it is used for closing The contacts that connect the circuit or open the circuit and disconnect the circuit are installed in the vacuum interrupter. When the contacts are closed or opened, arcs are not easy to occur, and the safety performance is very high. The function of the isolation knife switch is to establish a reliable insulation gap and separate the lines with an obvious disconnection point to ensure the safety of operators and equipment. When operating the vacuum circuit breaker to o...
