High-voltage transmission acousto-optic electroscope

Abstract

The invention discloses a high-voltage transmission acousto-optic electroscope comprising an outer rod, a middle rod and an inner rod. A handle is fixed at the bottom of the outer surface of the outerrod. The outer rod is provided with a slide slot. Two first fixing parts of central symmetry are fixed on the outer surface of the middle rod. A second fixing part is installed on the inner rod. A fixing plate is installed in the inner rod. An acousto-optic alarm is arranged on the fixing plate. The upper surface of the acousto-optic alarm is connected with an amplifier circuit through a wire. The amplifier circuit is connected with a resistor through a wire. The resistor is connected with a conductive contact through a wire. An anti-interference electrode is installed at the bottom end of the conductive contact. The high-voltage transmission acousto-optic electroscope has a simple structure. Through the anti-interference electrode, blind areas of voltage detection are eliminated, and hidden danger of personal safety brought about by improper operation is avoided. The height can be adjusted as needed through a telescopic rod. The angle can be adjusted as needed through the spirally upward slide slot. Therefore, the work intensity is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electric power detection equipment, in particular to an acousto-optic electric inspection device for high-voltage power transmission. Background technique [0002] As we all know, AC high-voltage power supply lines and high-voltage electrical equipment involve a wide range of users, and they are exposed to the sun for a long time and suffer from wind, sun, and rain. Therefore, in the power system, power outage maintenance and accident handling are essential and relatively frequent. One of the tasks, in order to ensure the safe operation of the equipment, the maintenance test of the power supply and transformation equipment must be carried out every year, and whether it is a maintenance test or accident handling, a power failure operation must be carried out before work, and the power test is indispensable in the operation In one link, when performing electrical inspection operations on high-voltage power ...

AI Technical Summary

Problems solved by technology

The dead zone of electric inspection is that the high-voltage equipment is indeed charged, but the phenomenon that the equipment is charged cannot be detected with a qualified electroscope

The blind area of ​​electric inspection generally appears in the larger part of the high-voltage live body of the substation or the corner of the wire connection and the angle between the high-voltage equipment and the connecting line. The electrical device cannot be adjusted according to the height of different equipment, and the efficiency is low; and because the electroscope is a light indicating type, when the equipment is far away and the sunlight interferes, the personnel operating on the ground cannot see the indicator light of the electroscope clearly , have an impact on the test results
