Days Hebei expanding electric equipment Co., Ltd. specializing in theproduction of acousto-optic high-pressure language AC electroscope(hereinafter referred to as the electroscope) is a kind of convenientcarrying, light weight, checking convenient electric new electroscope.The electroscope is used to the rated frequency 50Hz, voltage 10kV,35kV, 110KV, 220kV AC voltage, direct contact test power. Theelectroscope for generation, transmission, substation and industrial andmining enterprises in the electrical operation and maintenance personnelto verify there are no voltage ideal security tools, applicableenvironment temperature of 25 DEG to 55 DEG C; relative humidity20%~96%, use occasions for indoor and outdoor good weather. Indicatorworking power is 3 R03 (AAA) cells, the quiescent current is less thanor equal to 10 mu A, life is more than 5000 times of measuring points.
An acousto-optic signal strength indicator: alarm indicator intensity (1m 70Dd, 25m can be heard), ultra high brightness red flashing intensity (red flash, 15m direct light visible). Electroscope is always in standby mode, when battery voltage reduction is insufficient, the indicator light signal weak, that the battery should be replaced. Between the contact voltage up to the electroscope indicator clear indication delay (i.e. less than one second, the corresponding time) return coefficient is more than 0.95.
The electroscope has very high anti-interference performance, anti short circuit ability, anti electric spark performance and distinguish DC high voltage performance (no response to DC, indicating contact when short Beep).
Self detection function: high-voltage acoustooptical language AC electroscope circuit continuously monitored, as long as a press the test button, the electroscope will be issued: "dangerous, do not close to the" warning sound. Sound and light signals such as normal, has all circuit self detection function, it is proved that the electroscope indicator in the normal close state can be electrically operated for examination
