Product Overview：
A common method for evaluating whether the vacuum degree of a vacuum interrupter has deteriorated is the power frequency withstand voltage test. However, this method can only identify arc-extinguishing chambers with severely degraded vacuum levels. When the vacuum deteriorates to a range of 10⁻² to 10⁻¹ Pa, the breakdown voltage may remain unchanged, even though the arc-extinguishing chamber is already unqualified.
The Vacuum Switch Vacuum Tester addresses this limitation by employing a newly designed excitation coil and utilizing the magnetron discharge method to measure the vacuum level of the arc-extinguishing chamber—without the need for disassembly. With microcomputer-based synchronous control and advanced data acquisition and processing, the instrument achieves a field testing sensitivity of up to 10⁻⁵ Pa.
The most outstanding feature of this instrument is its ability to perform accurate vacuum measurement using a novel excitation coil and intelligent data processing, eliminating the need to dismantle the vacuum switch.
Widely used in industries such as electric power, steel, petrochemical, textile, coal, and railway—wherever vacuum switches are applied—the Vacuum Switch Vacuum Tester is a practical and reliable solution for on-site vacuum assessment.
