I. Product Introduction of WDZK-IV Vacuum Switch Vacuum Tester
WDZK-IV Vacuum Switch Vacuum Tester is a new generation product improved by our company based on WDZK-III according to feedback from field users. It features higher testing accuracy, better stability, and higher intelligence.
For vacuum circuit breakers, the common method to judge whether the vacuum degree of vacuum tubes has deteriorated is the power frequency withstand voltage method, which can only judge arc extinguishing chambers with severely deteriorated vacuum degree. When the vacuum degree deteriorates to 10-2----10-1 Pa, although the breakdown voltage does not decrease, the arc extinguishing chamber is already unqualified. The WDZK-IV Vacuum Switch Vacuum Tester adopts a new type of excitation coil and uses the magnetic control 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 processing, making the field testing sensitivity of the arc extinguishing chamber vacuum degree reach 10-5Pa. The prominent feature of this instrument is the adoption of a new type of excitation coil and data processing method, achieving non-disassembly measurement of vacuum degree. This instrument has the advantages of convenient use, simple operation, non-disassembly measurement, and high testing accuracy. It is a practical detection instrument widely applicable to departments using vacuum switches such as electric power, steel, petrochemical, textile, coal, railway, etc.
