Impulse voltage generator

Abstract

The invention provides an impulse voltage generator. The generator comprises a rack, a capacitor, an insulation pull rod, an insulation synchronization belt and a discharge apparatus. The rack comprises a base plate 105, an insulation support column, an insulation crossbeam 103 and a conductive seat. The discharge apparatus comprises a metal block, a conductive tension spring and a conductive belt. During charging, capacitors, the capacitor and the conductive belt, the capacitor and the conductive seat and the like are disconnected so as to realize the charging. During discharging, the insulation synchronization belt moves so as to drive the insulation pull rod to move and drive the metal block to move. When the metal block moves to an adjacent capacitor pole, a loop is formed between all the capacitors and the conductive seat so that positive and negative electrode discharge of the capacitors and discharge to the ground are realized. Discharge time of the impulse voltage generator is short and structure operation is stable and reliable.

Description

technical field [0001] The invention relates to a high-voltage generating device for generating pulse waves, in particular to an impulse voltage generator. Background technique [0002] Impulse voltage generator is a generating device that generates lightning impulse and operating impulse voltage. The resulting impulse voltage can be used for the impulse withstand or discharge test of the insulation. In high-power electron beam and ion beam generators and carbon dioxide lasers, the impulse voltage generator can be used as a power supply device, which is an important part of the high-voltage nanosecond pulse power generator. The impulse voltage generator consists of a group of high-voltage capacitors for energy storage. After being charged by a DC high-voltage source for tens of seconds, it is suddenly discharged through the resistance through the ignition device, forming an impulse voltage waveform with a steep rising front on the test product. The duration of the shock wa...

AI Technical Summary

Problems solved by technology

There are certain disadvantages in this charging and discharging method: 1. The steel wire and the insulating rope are wound on the pulley. During the movement, they often fall out of the guide rail due to the consistency and are stuck; 2. The steel wire and the insulating rope will loosen after a period of use. It leads to unsatisfactory charging and discharging; 3. It is necessary to connect the insulating rope and the steel wire in series, and it is difficult to connect the two in series due to different materials; 4. It takes a long time to switch between the steel wire and the insulating rope, and it is necessary to run all the insulating ropes The insulating rope of the whole loop can only be replaced
