Product Details
1. Product Name:
Circuit Breaker Vacuum Degree Tester
2. Equipment Description:
HYKZ-Ⅳ vacuum tester for vacuum switchgear is the latest generation
of products of my company, it is the upgrade product in the base of
HYKZ-Ⅲ vacuum meter on the foundation of notion from the field
user. HYKZ-Ⅳvacuum 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 HYKZ-IV vacuum 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, HYKZ-IV vacuum tester
also used computer for synchronous control, data acquisition and
processing, and the sensitivity of HYKZ-IV vacuum tester in the
field test of the vacuum interrupter arc chamber is 10 -5 Pa. The
most prominent feature of this instrument (HYKZ-IV vacuum tester)
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.
