High-voltage alternating-current on-off test system based on signal generator triggering

Abstract

The invention provides a high-voltage alternating-current on-off test system based on signal generator triggering, which belongs to the technical field of high-voltage switches. The high-voltage alternating-current on-off test system is characterized in that time delay is set for a signal generator, a conduction signal is given to a main loop switch and a thyristor of an LC experimental loop, the signal generator controls a circuit to discharge to realize switching off operation, meanwhile, video acquisition equipment receives a trigger signal, shoots the arc in a vacuum arc extinguishing chamber by taking the moment as a zero point or sends a motion mechanism of a quick vacuum switch to data processing equipment, and an oscilloscope receives the trigger signal, receives the current and voltage of the arc and the current of a quick vacuum switch control circuit. According to the high-voltage alternating-current on-off test system, the vacuum arc extinguishing chamber is combined with the vacuum quick switch, the switching off speed can be controlled while the switching off speed is improved, the action time sequence of each part is controlled by adjusting the time sequence of signals sent by the signal generator, the arc behavior and the movement process of the motion mechanism can be completely shot, the current and voltage can be measured, and the personal safety can be ensured by being far away from experimental equipment during experiment.

Description

Technical field [0001] The present invention belongs to the technical field high-voltage switch, particularly to a high voltage based on the AC signal generator triggered breaking test system. Background technique [0002] Experimental study is an effective means of vacuum arc, Study on vacuum arc plasma parameters include measured between the measuring electrode and vacuum arc shape observation, the arc voltage. Due to the high test voltage exceeds the safe voltage of human body, with a certain degree of risk, so the experiment can be remotely operated well protect the personal safety of laboratory personnel. Experimental set apart from the previous arc usually triggered ignition mode, in recent years, with the gradual emergence of separable interrupter actuator mechanism currently used is a permanent means, such as the need for higher opening speed, can be quickly selected repulsion mechanism. [0003] In recent years, based on an electromagnetic repulsion mechanism of the rapi...
