Description

WDZK-IV vacuum switch vacuum tester adopts a new type of excitation coil, and uses the magnetron discharge method to test the vacuum degree of the arc extinguishing chamber without disassembling 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 arc extinguishing chamber reaches 10-5Pa. The most prominent feature of this instrument is that it adopts a new type of excitation coil and data processing method, which realizes the measurement of vacuum degree without disassembly. This instrument has the advantages of convenient use, easy operation, no disassembly and high measurement 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.
