ZKD Vacuum Bottle Integrity Test Instrument for vacuum interrupter is the latest generation of products of my company, it has many advantages,such as high measurement accuracy, better stability, more capacity.
For vacuum circuit breaker, the method of
determining deterioration of the vacuum tube is 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 this vacuum
bottle tester for vacuum switch, the new field coils were
used, and with the magnetron discharge method the vacuum of the
vacuum 3 3 / 9 9 interrupter arc can be measured without
disassembling the interrupter arc chamber. At the same time, ZKD Vacuum Bottle Integrity Tester also uses computer for synchronous control, data acquisition
and processing, and the sensitivity of vacuum bottle tester in the
field test of the vacuum interrupter arc chamber is 10 -5 Pa.
The most prominent feature of this vacuum degree tester is to use the new excitation coils and data processing methods to achieve the non-demolition measurement of vacuum. The tester 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.
