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.
הvacuum interrupter 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 vacuum interrupter test set manufactures achieves a field testing sensitivity of up to 10⁻⁵ Pa.
The most outstanding feature of this vacuum interrupter tester is 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 interrupter tester is a practical and reliable solution for on-site vacuum assessment.

FAQ about Vacuum Interrupter Test Set
Q: What is a vacuum interrupter tester, and what does it primarily detect?
A: Vacuum interrupter tester is a specialized power testing device used to inspect the internal vacuum condition and insulation performance of the interrupter in high-voltage vacuum circuit breakers. By measuring the internal vacuum degree and assessing vacuum retention capability, it effectively evaluates the operational reliability of the vacuum circuit breaker.
This vacuum interrupter tester manufactures is primarily used in vacuum circuit breaker production inspection, installation commissioning, preventive maintenance, and fault diagnosis, to identify potential issues such as interrupter air leakage, vacuum degradation, and reduced insulation performance.
Q：Why is it necessary to measure the vacuum degree with a vacuum interrupter tester?
A: The vacuum interrupter tester supplier relies on a high-vacuum environment to achieve rapid arc extinction and insulation recovery between contacts. If the internal vacuum level decreases, the arc-quenching capability and insulation performance will be affected, potentially leading to reduced breaking capacity, contact erosion, or even equipment failure.
By regularly measuring the vacuum degree, the performance degradation trend of the interrupter can be identified in advance, preventing power outages caused by equipment failure and improving the operational safety of the power system.
Q: Why is regular vacuum degree testing required for vacuum circuit breakers?
A: During long-term operation, vacuum interrupters may be affected by mechanical impact, temperature variations, contact wear, and seal aging, which can gradually degrade internal vacuum performance.
Regular testing can:Identify vacuum performance abnormalities in advance;Prevent circuit breaker interruption failure;Reduce unexpected power outages;Extend equipment service life.
Q: What is the primary purpose of the Vacuum Interrupter Test Set?
A: The primary purpose is to quantitatively measure the vacuum level inside vacuum switch arc-extinguishing chambers. This helps determine if the vacuum has degraded to a level that could compromise the switch's ability to interrupt fault currents, allowing for preventive maintenance before failure occurs.
Q: Why is quantitative measurement important compared to traditional withstand voltage testing?
A: Traditional power frequency withstand voltage testing can only identify arc chambers with severely deteriorated vacuum (when breakdown voltage has already decreased). It cannot detect vacuum degradation in the range of 10⁻² to 10⁻¹ Pa, where the chamber is already unqualified but breakdown voltage has not yet dropped. The Vacuum interrupter tester manufacturer provides quantitative values, allowing detection of vacuum degradation at an earlier stage.
