Vacuum Switch Vacuum Degree Tester

Product Introduction

Vacuum circuit breaker is a common method for judging whether the vacuum degree of vacuum tube is degraded or not is the power frequency withstand voltage method. This method is only an arc extinguishing chamber that can judge the degree of vacuum degradation. When the vacuum degree deteriorates to 10-2-10-1 Pa, although the breakdown voltage does not decrease, the arc extinguishing chamber is no longer qualified. The vacuum degree measuring instrument adopts a new type of excitation coil and uses the magnetron discharge method to test the vacuum degree of the arc extinguishing chamber without dismantling the arc extinguishing chamber. At the same time, a microcomputer is used for synchronous control and data acquisition and processing, so that the on~site test sensitivity of the vacuum degree of the interrupter reaches 10~5Pa. The most prominent feature of the vacuum degree measuring instrument is that it adopts a new type of excitation coil and data processing method to realize the vacuum degree measurement without disassembly. The vacuum degree measuring instrument has the advantages of convenient use, simple operation, non~disassembly measurement and high test accuracy. It is a practical detection instrument and is widely used in electric power, steel, petrochemical, textile, coal, railway and other departments that use vacuum switches.
