II Function Overview
Along with the gradual rise of the voltage level of national transformer stations, the
usage of SF6 High voltage circuit breakers has been increasing by about 15% each
year. In the field of high pressure, extra-high pressure and ultra-high pressure switches,
SF6 has become the only insulating and arc extinguishing medium. Yet SF6 high
pressure switches are commonly installed indoor where the air motion is relatively slow,
so once a gas leak of SF6 occurs, it usually causes local oxygen deficit, which
asphyxiates working personnel and puts their lives in great danger. Furthermore, it
greatly reduces the arc extinguishing effects on high pressure control breakers, which
would damage the breakers themselves. So once a SF6 gas leak is discovered, relative
measures must be taken and the leaking point must be found and restored to eliminate
the potential safety hazard to the high pressure control breakers.
HTJL-V High Precision SF6 Gas Leak Detectorr can not only run optical alarms
according to the concentration thresholds set by customers, but it can also accurately
find leaking points of SF6 and apply quantitative detection on the leaking quantity,
annual leaking rate of SF6 control breakers and GIS in a variety ways such as observing
the trend of data change, which brings great convenience in SF6 device maintenance.
