XSL8004 Vacuum Switch Vacuum Degree TesterThe common method to judge whether the vacuum degree of a vacuum tube is deteriorated is the power frequency withstand voltage method, which can only judge the vacuum degree of the arc extinguishing chamber. When the vacuum degree deteriorates to 10－2----10－1Pa, although the breakdown voltage does not decrease, the arc extinguishing chamber is already unqualified.
The vacuum switch vacuum degree tester adopts a new type of excitation coil and uses the magnetic discharge method to test the vacuum degree of the arc extinguishing chamber without disassembling it. 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 arc extinguishing chamber vacuum degree reaches 10－5Pa. The most prominent feature of this instrument is the use of a new type of excitation coil and data processing method, realizing non-disassembly measurement of vacuum degree. This instrument has the advantages of convenient use, simple operation, non-disassembly measurement, and high test accuracy.
