Current data transmission stores to external memory device, and the quantitative test data that have recorded pressure test each time is the most convenient
Later stage checks, although but on the other hand can filtering out the qualified insulating properties of pressure test further and start preliminary exception occur
Insulating bar, in order to Security Officer takes precautions against in advance.(3) this utility model insulating bar detection device connects on each insulating bar
One current transformer, analyzer gathers the faradic current size in current transformer, and current transformer has proportionally reduced
Enter the current value of analyzer, prevent from causing because insulating bar insulating properties are the poorest big electric current to enter analyzer and burn analyzer or
Person injures testing crew.(4) this utility model insulating bar detection device arranges anchor ear with fixed insulation bar, prevents from leading because of electric leakage
Cause insulating bar escape and produce test incident.
