ZKY-2000Vacuum Tester

One, overview

Vacuum circuit breaker is widely used in high-voltage electrical power system, the core of vacuum interrupter parts are, as the interrupter is a vacuum as a working basis, so it's not like oil switch, SF6 switch as easily determine its quality. Traditionally, users determine the arc-quenching Chamber of vacuum of vacuum circuit breaker power frequency withstand voltage is the method method, this method can only roughly assess the vacuum interrupter of deterioration.

ZKY-2000Vacuum vacuum interrupter Tester is identification of vacuum equipment, mainly by single-chip computer control unit, test process is completely automated. The sampling design of the instrument changed uses peak current calibration methods, and Ionic charge is used to do the calibration. In this way, effectively instantaneous power disturbance during the test, the test is stable and reliable. As a result of the computer main control unit, the instrument can be conveniently deducted leakage currents due to environmental factors. This instrument most highlight of features is: achieved has vacuum out arc room of from demolition measurement, directly displayed vacuum degrees value, makes vacuum circuit breaker device user detailed master out arc room of vacuum State, for has plans to replaced out arc room provides has reliable of according to, for grid of security run provides has powerful guarantees, overcome has workers frequency resistance pressure method only can judge out arc room whether scrap of defects.

This instrument provides high accuracy, easy to operate, easy to carry, strong anti-jamming ability, especially suitable for power supply unit tests is the production of vacuum circuit breaker, installation, commissioning and maintenance one of the necessary equipment.

The second, measuring principle

Two contact interrupter stood some distance, applying high voltage pulse, and residual gas molecule ionization, the ion current and residual gas density is proportional to the vacuum. For different vacuum tube, under the same conditions of vacuum and ion current is not the same size, when sensing a ion current through vacuum ion current curve, done automatically by the computer calculation of the vacuum, and vacuum value is displayed.
