Problems solved by technology

However, under the working conditions that require fast conduction for a certain period of time, the vacuum switch needs to complete the switching between the conduction state and the rapid disconnection state in a short period of time, which requires the operating mechanism of the switch and the performance requirements of the vacuum interrupter. Extremely high, almost impossible

Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] The invention provides a driving method for one-way closing and splitting electrodes, such as figure 1 As shown in (a), firstly, the moving electrode 2 is arranged on one side of the static electrode 1, and the moving electrode 2 and the static electrode 1 are in an open state, and the moving electrode 2 is opposite to the trigger hole 3, and the operating mechanism drives the guide rod 4 and The moving electrode 2 moves in a straight line towards the direction close to the static electrode 1; figure 1 As shown in (b), when the moving electrode 2 passes through the trigger hole 3 and just comes into contact with the static electrode 1, the moving electrode 2 and the static electrode 1 change to the closing state at this time, and the time to maintain the closing state begins to be calculated; figure 1 As shown...

Abstract

The invention discloses a driving method and a structure of a one-way on-off electrode. According to the driving method, a moving electrode is arranged on one side of a static electrode; a trigger hole for allowing the moving electrode to pass through is formed in the static electrode; the moving electrode and the static electrode are in a separated state; the moving electrode can move in a direction close to the static electrode; when the moving electrode passes through the trigger hole, the moving electrode is in contact with the static electrode; the moving electrode continuously moves in the direction to reach the other side of the static electrode, and the moving electrode and the static electrode are separated to the specific position, and the electrode completes one time of on-off actions, wherein the switch-on state maintaining time t of the electrode structure can be controlled according to the length of the contacted sections of the moving electrode and the static electrode,and the movement speed of the moving electrode. Quick on and off of the electrode structure can be realized by virtue of motion of the moving electrode in the same direction, and the switch-on state maintaining time t can be adjusted by changing the movement speed of the moving electrode or the dimension of the electrode.

Description

technical field [0001] The invention belongs to the technical field of power switches, and relates to a driving method of a unidirectional closing and opening electrode, and also relates to a structure of a unidirectional opening and closing electrode. Background technique [0002] In recent years, with the rapid development of my country's electric power industry and the enhancement of environmental protection awareness, the production, transmission, and consumption of electric energy are moving towards clean, efficient, and diversified directions. As a result, the demand for new power equipment is also growing. In particular, for the requirement of fast turn-on power switches for a specific period of time (several ms), fully controlled power semiconductor devices (such as MOSFETs, IGBTs, IGCTs, etc.) may be the best choice. [0003] However, this type of switch currently has the disadvantages of small capacity and low withstand voltage, so it is widely used in low-voltage...
