The common method to judge whether the vacuum degree of a vacuum circuit breaker is deteriorating is the power frequency withstand voltage method, which can only determine the arc extinguishing chamber with severely deteriorated vacuum degree. When the vacuum degree deteriorates to10-2----10-1 Pa, although the breakdown voltage does not decrease, the arc extinguishing chamber is already unqualified.
The HKZK-E 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 processing, making the on-site test sensitivity of the arc extinguishing chamber vacuum degree reach10-5Pa.
Functional Features:
The most prominent feature of the HKZK-E Vacuum Switch Vacuum Degree Tester is the use 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 test accuracy. It is a practical detection instrument widely applicable to departments using vacuum switches such as electric power, steel, petrochemical, textile, coal, railway, etc.
