High voltage electroscope based on electro-optic effect

Abstract

The invention discloses a high voltage electroscope based on an electro-optical effect. The high voltage electroscope comprises an electric field intensity sensing module, a signal transformation and pretreatment module, a data acquisition module, a data processing module, an alarm module, a power supply module and an L-GPS (Global Positioning System) positioning module. The high voltage electroscope based on the electro-optic effect has the advantages of calculating the high voltage power line source orientation of the sensor module, pointing out which conductors are live, and giving high voltage electrified alarm by detecting the electric field intensity of each point on reference relevant path of relevance zero point and high voltage detection points positioned by the L-GPS module at high precision; if the vector of each point is superimposed, calculating the voltage of a target live conductor relative to the reference zero to give the high voltage electrified level of the target conductor; detecting whether the conductor has alternating or direct current high voltage, high voltage target conductor orientation and the like, and having less interference and relative safety.

Description

Technical field [0001] The present invention relates to a high-voltage electroscope, in particular to a high-voltage electroscope based on the electro-optical effect. Background technique [0002] The electroscope is one of the common tools used to detect that electrical equipment is live. The "State Grid Corporation Electric Power Safety Work Regulations" clearly stipulates that before working on some power-off electrical equipment or installing the ground wire in the work area of ​​the power-off line, the power must be checked first to verify that the equipment or line has been powered off before performing other operations to prevent Vicious accidents occur, such as the grounding wire of the live installation, the grounding switch, and the accidental touching of the live equipment. Therefore, checking whether the AC and tributary high voltage or ultra-high voltage or UHV equipment is live is related to the life safety of operation and maintenance personnel, and is of great si...

Problems solved by technology

This increases the operational complexity of the measurement process; and the ground wire needs to be close to the target high voltage during measurement, which is likely to cause high voltage to discharge to the ground, causing serious faults such as line-to-ground short circuit, and posing a serious threat to the normal operation of the power system and equipment safety

The aluminum foil electrometry method isolates the high voltage from the ground, which is not easy to cause accidents, but the aluminum foil needs to be close to or even in contact with the high voltage during measurement to obtain whether the target conductor has high voltage, and the high voltage range is not easy to accurately determine

When the above methods target multiple conductors at the same time, which conductor or conductors carry high voltage requires multiple tests. Before the test, the test target is unclear and the operation is time-consuming.
