interrupter vacuity tester

The common method to judge whether the vacuum degree of vacuum tube is deteriorated or not is power frequency withstand voltage method. This method can only judge the interrupter with serious vacuum degree deterioration. However, when the vacuum degrades to 10-2～10-1 PA, although the breakdown voltage does not decrease, the interrupter is not qualified. RDZK-208 vacuum switch vacuum tester adopts excitation coil and magnetic controlled discharge method to test the vacuum degree of arc extinguishing chamber without dismantling the arc extinguishing chamber. At the same time, the microcomputer is used for synchronous control and data acquisition and processing, so that the field test sensitivity of the vacuum degree of the interrupter reaches 10-5Pa. The outstanding feature of vacuum switch vacuum degree tester adopts excitation coil and data processing method to realize the measurement of vacuum degree without disassembly. Vacuum switch vacuum degree tester has the advantages of convenient use, simple operation, no disassembly, high measurement and test accuracy. Interrupter Vacuity Tester is a practical testing instrument, which is widely used in electric power, steel, petrochemical, textile, coal, railway and other departments using vacuum switch
