摘要
介绍了基于磁控放电原理的真空度测试仪的研制。测试仪以PLC为主机控制高压脉冲电压源和磁场电流源,实现本地和远程的真空度测量。该测试仪可用于真空断路器单独测量或真空泡出厂检测流水线作业,测量灵敏度高、范围大。
The functional requirements of a vacuum pressure measurement machine based on the principle of magnetron discharge was described. The machine uses a PLC as core to control a high voltage pulse power and a field current power,and to perform local and remote pressure measurement.This machine is applicable for measurement or manufacturer s measurement pipelining of vacuum interrupter,with measurement merits of high sensitivity and wide range.
