Vacuum CB Switch Tester for vaccum circuit breaker, hv switchgear test
I. Introduction.
The vacuum tester has some features-higher measurement accuracy, better stability, more capacity.
For vacuum circuit breaker, the method of determining whether or not deterioration of the vacuum tube is inspection with the method of frequency withstand voltage, but this method only distinguish the vacuum interrupter arc chamber of the serious deterioration. When the vacuum of vacuum interrupter arc chamber degrade to 10-2-10-1 Pa, although the breakdown voltage is not reduced, but the interrupter arc chamber has failed. In the vacuum tester for vacuum switch, the new field coils were used, and with the magnetron discharge method the vacuum of the vacuum interrupter arc can be measured without disassembling the interrupter arc chamber. At the same time, the vacuum tester also used computer for synchronous control, data acquisition and processing, and the sensitivity of the vacuum tester in the field test of the vacuum interrupter arc chamber is 10-5Pa. The most prominent feature of this instrument is to use the new excitation coils and data processing methods to achieve the non-demolition measurement of vacuum. The instrument is practical, easy to use, easy to operate, high precision measurement without disassembly, widely used in electric power, steel, petrochemical, textile, coal, railways, and other trades using the vacuum switch.
