Product Introduction
As an indispensable testing equipment in the power system, the core function of the vacuum interrupter tester is to accurately measure the vacuum degree of the vacuum interrupter. The tester adopts the advanced magnetron discharge principle, applies pulsed high voltage to the interrupter and detects the generated ion current, so as to accurately calculate the vacuum degree.
Product Features
Stable Electric Field Output
The vacuum interrupter tester can output 20 volts, accurately simulating the electric field environment of the vacuum interrupter when it is working, and the electric field output is stable, ensuring accurate test results.
Efficient Magnetic Field Operation
The magnetic field voltage of the vacuum interrupter tester reaches 1600 volts, and the strong magnetic field generated can deeply detect the performance of the vacuum interrupter in a strong magnetic field environment.
High-precision Detection Performance
The vacuum interrupter tester adopts advanced signal processing algorithms, and the vacuum degree detection accuracy reaches ±0.1Pa, which can accurately detect changes in the vacuum state of the interrupter.
