Circuit Breaker Series Vacuum Switch Vacuum Tester The HZ-KG7 Vacuum Switch Vacuum Tester adopts a new type of excitation coil and uses the magnetron discharge method to test the vacuum of the arc-extinguishing chamber without dismantling. It has a microcomputer for synchronous control as well as data acquisition and processing, so that the on-site vacuum test sensitivity of the arc-extinguishing chamber reaches 105Pa. This instrument has the advantages of convenient use, simple operation, non-disassembly measurement, and high test accuracy. It is a practical testing equipment widely used in electric power, steel, petrochemical, textile, coal, railway and other sectors that use vacuum switches.
