Problems solved by technology

In this setting, the voltage that the load switch can carry is low, and cannot be applied to the increasing voltage level requirements
When the incoming line terminal is connected to electricity and the vacuum interrupter is not conducting, it is easy to generate a large arc and be broken down at the moment of power supply and under high voltage of lightning.

Embodiment Construction

[0022] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] Such as Figure 1 to Figure 3 As shown, an isolated linkage vacuum load ring network cabinet includes a cabinet body, a switch mechanism 2 and an operating mechanism 1; the cabinet body is provided with a separated vacuum switch chamber, an operating mechanism chamber and a cable chamber. The switch mechanism 2 includes a first connecting terminal 21, an isolating switch 22, a vacuum interrupter 23 and a second connecting terminal 24 which are electrically connected in sequence. The switching mechanism 2 also includes a first rotor 25 and a The second rotor 26 used to control the on-off of the vacuum interrupter 23, the operating mechanism 1 is connected to the first rotor 25 and the second rotor 26; the operating mechanism 1 is used to control the linkage between the isolation switch 22 and the vacuum interrupter 23. The f...

Abstract

The invention discloses a vacuum load ring network cabinet which is isolated and linked, The switching mechanism comprises a first wiring terminal, an isolating switch, a vacuum interrupter and a second wiring terminal which are electrically connected in turn. The switching mechanism further comprises a first rotor for controlling the on-off of the isolating switch and a second rotor for controlling the on-off of the vacuum interrupter. The operating mechanism is simultaneously connected to the first rotor and the second rotor. The operating mechanism is used to control the linkage between thedisconnector and the vacuum interrupter. The vacuum load switch has a high interrupting voltage, which meets the requirements of high voltage level. The vacuum load switch has a high interrupting voltage. Disconnector and vacuum arc extinguisher are interconnected, vacuum load switch is not easy to start arc; The breaks of disconnector and vacuum interrupter can be closed in millisecond order. After the arc produced by transient closing of disconnector is quickly extinguished, the vacuum interrupter can be closed safely, and the vacuum load switch has higher safety and reliability.

Description

technical field [0001] The invention relates to a high-voltage switch, in particular to an isolation and linkage vacuum load ring network cabinet. Background technique [0002] With the continuous improvement of voltage level requirements, the breaking voltage requirements of high-voltage load switches continue to increase. [0003] In the prior art, some manufacturers only set up a break of the vacuum interrupter between the inlet terminal and the outlet terminal of the load switch, and the safety level is relatively low; the vacuum interrupter can only be reliably applied to lower voltage levels A system, such as a 72kv power system. In this arrangement, the load switch can carry a relatively low voltage, which cannot be applied to the increasing voltage level requirements. When the incoming line terminal is connected to electricity and the vacuum interrupter is not conducting, it is easy to generate a large arc and be broken down at the moment of power supply and under ...
