The high-voltage electroscope has the following advantage: the UV sensor can convert UV signals into measurable electric signals, can detect a circuit over a long distance, is free from contact with a high-voltage cable or live-line equipment, and is accurate in live part verification result.

Description

technical field [0001] The present invention mainly relates to the field of electric tools, in particular to a high-voltage piezo electric appliance. Background technique [0002] When the high-voltage line is powered off for maintenance, the regulations of power outage, power inspection, and hanging to the ground must be followed, and the power inspection operation must be completed through an electroscope. The electroscope is one of the commonly used power safety tools used to detect whether there is voltage on the power equipment. Through the electroscope, it can be clearly verified whether the power-off equipment has no voltage, and then other operations are performed to prevent the occurrence of live grounding wires (closing the grounding knife switch) , accidental touch with electrical equipment and other vicious accidents. [0003] Traditional electroscopes are all portable, and usually the electroscope is installed on the operating rod. When operating, the electrosc...

AI Technical Summary

Problems solved by technology

[0004] 1. With the emergence of ultra-high voltage and long-distance power grids, the higher insulation requirements for power grids are constantly increasing, and the distance between high-voltage power grids and the ground is relatively long, especially for UHV transmission lines with high towers and large spans. The operating rod is difficult to control, resulting in inaccurate electrical inspection, and the operator is likely to stray into the electrified interval to operate while holding the rod, causing personal injury and death accidents from time to time, and also highlights the existing contact electroscope Insufficient sensitivity of electrical inspection and difficulty in predicting the danger of discharge;

[0005] 2. At present, when the high-voltage electroscopes used in China are conducting electric inspections of high-voltage equipment, due to the uneven electric field of the line oxide layer or the electric field of the equipment, there are often problems that the electric inspection cannot be performed reliably due to the long response time of the electroscope. It directly leads to the misjudgment of the staff that the high-voltage equipment has no electricity, which may cause personal injury accidents

[0006] 3. The existing electroscopes have relatively poor anti-interference ability and are easily affected by external interference. The measurement of whether the line or live equipment is live and the amount of charge is inaccurate, which not only reduces the work efficiency of the operator, but also may cause casualties;

[0007] 4. The existing electroscope is not waterproof and cannot be used in rainy and snowy weather. However, since ensuring the normal supply of electricity is related to all aspects of people's lives, in special cases in rainy and snowy weather, it is necessary to repair the power grid and power equipment. Bring a lot of trouble and potential danger to the operator;

[0008] 5. Although the existing electroscope is small and easy to carry, the operator may forget to carry the electroscope during work, or place the electroscope everywhere after work, resulting in the loss of the electroscope and bringing a lot of unnecessary troubles to the operator. trouble
