Abstract

The present invention relates to a high-speed vacuum circuit breaker based on eddy current drive. The high-speed vacuum circuit breaker comprises a shell as well as a vacuum arc extinguish chamber, an operating mechanism and a control circuit which are mounted on the shell; a fixed static conductive contact and a movable conductive contact positioned right below the static conductive contact are arranged in the vacuum arc extinguish chamber; a lower end of the movable conductive contact extends out of the vacuum arc extinguish chamber and is fixedly connected to a connecting rod by an insulating tension pole; leading-out terminals which extend towards the outside of the shell and are used for connecting a bus are formed at end parts of the static conductive contact and the movable conductive contact; and an operating mechanism apparatus for enabling the movable conductive contact to move up and down by a magnetic flux force so as to reach a switching-off or switching-on position and the control circuit for controlling the operating mechanism apparatus to execute the switching-off or switching-on action are arranged on the connecting rod. The vacuum circuit breaker disclosed by the present invention has a simple structure and low costs, and switching-on and switching-off of the vacuum circuit breaker are controlled by an induced magnetic field and the control circuit, so that switching-on and switching-off speeds and stability of the vacuum circuit breaker are improved.

Description

technical field [0001] The invention relates to the technical field of vacuum circuit breakers, in particular to a high-speed vacuum circuit breaker based on eddy current drive. Background technique [0002] In the current vacuum circuit breaker products, the opening and closing speed of the circuit breaker is not high, and the opening and closing time is tens of milliseconds. For such a long time, it has been difficult to achieve a protective effect in some special occasions. In some protection devices, such as fast switching devices, switch-type series compensation devices, etc., a high-speed vacuum circuit breaker is required. Contents of the invention [0003] The purpose of the present invention is to provide a high-speed vacuum circuit breaker based on eddy current drive, which improves the speed and stability of opening and closing of the vacuum circuit breaker. [0004] In order to achieve the above object, the present invention adopts the following technical sol...
