Abstract

The invention discloses a full-loop alternating-current self-test high-voltage electroscope with a dead zone protection function. The high-voltage electroscope comprises a high-voltage electroscope body and a plurality of sections of telescopic insulation rods, wherein the high-voltage electroscope body comprises a high-voltage electroscope probe, a housing, a full-loop self-test indication lamp, a direct-current power set cabin, a voltage shortage indication lamp, a self-test button switch, a sound-light generator and a full-loop self-test electroscope circuit; a connecting part is arranged at one end of the lower end surface of the housing; the upper end parts of the plurality of telescopic insulation rod are in threaded connection with the connecting part. As a conventional full-loop self-test high-voltage electroscope is improved, the dead zone protection function unconfigured in a general full-loop self-test high-voltage electroscope is configured, and resistors and capacitors of an input loop are matched, the response time of the electroscope in a process of detecting a low voltage is shortened, the sensitivity of the full-loop self-test high-voltage electroscope is improved, and a safety operation can be reliably guaranteed.

Description

technical field [0001] The invention relates to a high-voltage electrical inspection device, in particular to a full-circuit AC self-inspection high-voltage electrical inspection device with a dead zone protection function. Background technique [0002] At present, when the high-voltage electroscope used in China is used for electric inspection of high-voltage equipment, due to the uniform electric field of the line oxide layer or the electric field of the equipment, there are often problems that the electroscope itself cannot be reliably inspected due to its high starting voltage and long response time. . If the electroscope cannot correctly indicate that there is electricity in its own dead zone voltage range, it will directly lead to the staff's misjudgment that the high-voltage equipment has no electricity, which may cause personal injury accidents. Therefore, it is necessary to design an electroscope with dead zone voltage protection to meet the characteristics of shor...
