Expansion and contraction of high voltage electroscope Contact windmill electroscope Portable acousto optic stick 35/110/220kv Item NO.: 1948846

Windmill type high voltage electroscope component: it indicates whether the working voltage on the contact electrode exists. The utility model can be a split type of insulating rod which can be assembled, or can be directly made into a whole with the insulating rod.

principle

When the electroscope indicating system is charged, the indicator will deflect due to the repulsive force of the same charge. It reflects the charged conductor from the angle of force. When the indicator system has a certain deflection angle, its weight moment and static moment are balanced.

characteristic

Before using the windmill electroscope, it is necessary to observe whether the blade of the rotary indicator is off-axis. The off-axis operator is not allowed to use the windmill electroscope. Gently shake the electroscope, and the blade should shake slightly. When using the windmill electroscope, it should be close to the tested equipment gradually. Once it indicates that the blade starts to rotate normally, it means that the equipment has electricity. It should leave the tested equipment immediately, and do not make the blade rotate for a long time, so as to ensure the service life of the electroscope. Windmill electroscope is only suitable for indoor or outdoor use in good weather. It is forbidden to use in rainy and snowy days. The windmill type high-voltage electroscope shall not be subject to strong vibration or impact, and shall not be debugged and disassembled by itself
