Abstract

The invention discloses an explosion chamber experiment device mainly comprising an explosion chamber, a top pressure strip, a super-path support plate, an intermediate mending plate, a bottom supportplate, a drive mechanism, an insulation pull bar with a built-in super path spring, a drive mechanism layer insulation chock support rod, an insulation pull bar layer insulation chock support rod, anexplosion chamber layer insulation chock support rod, and a super path gap; the explosion chamber experiment device can detect various parameters of the explosion chamber, is simple in design, easy to operate, small in measure condition dispersibility, reliable in performance, more accurate and stable in the super path amount preset aspect, and more suitable for detecting explosion chamber performances.

Description

technical field [0001] The invention relates to the field of high-voltage circuit breakers, in particular to an experimental device for an arc extinguishing chamber. Background technique [0002] The high-voltage vacuum circuit breaker is named for its high-vacuum arc-extinguishing medium and the insulating medium of the contact gap after arc-extinguishing; it has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc-extinguishing. Internet applications are more popular. [0003] In order to meet the mechanical parameter requirements of the vacuum interrupter, ensure the electrical and mechanical performance of the vacuum circuit breaker, and ensure the reliability of operation, the vacuum circuit breaker must have stable and good mechanical properties. And it is necessary to test the characteristics of the circuit breaker. The main detection parameters are: opening distance, contact pressure, contact travel, closing speed,...
