Contact-type and non-contact-type sensors and electricity inspecting method adopting same

Abstract

The invention relates to the technical field of electricity inspecting methods of high-voltage electroscopes, in particular to contact-type and non-contact-type sensors and an electricity inspecting method adopting the same. The electricity inspecting method of a high-voltage electroscope with the double sensors refers to a signal collecting module, a contact-type signal conditioning circuit, a non-contact-type signal conditioning circuit, a signal processing circuit, a sound-light alarm circuit, a Bluetooth transmission module and a mobile phone monitoring part; and two ways of signals outputby the contact-type and non-contact-type sensors are collected, and subjected to logical judgment. Whether the current alarm type is contact-type alarming or non-contact-type alarming is judged according to the frequencies of the alarming signals, the distance between the electroscope and to-be-inspected equipment is judged according to the different frequencies of the alarming signals, thus monitoring personnel learn the electricity inspecting result in real time, the credibility and reliability of the electricity inspecting result are greatly improved, the safety of electricity inspecting and maintenance personnel is improved, the accuracy of the electricity inspecting result is improved, the false alarm rate is decreased, and whether the to-be-detected equipment is electrified or not is effectively detected.

Description

technical field [0001] The invention relates to the technical field of a high-voltage electroscope electroscope method, in particular to an electroscope method using contact and non-contact sensors, which is a dual-sensor high-voltage electroscope electroscope method. Background technique [0002] High-voltage electroscope is a kind of electric equipment used for high-voltage electric power maintenance, and is used to judge whether the equipment to be repaired is charged or not. High-voltage electroscopes are divided into contact and non-contact electroscopes. Among them, the contact electroscope directly contacts the equipment to be tested and uses the principle of space stray capacitance voltage division to realize the electroscope, which is the most widely used. The non-contact electroscope judges whether the device under test is charged by collecting the electric field strength in space. Since the technology is not mature enough, it is still in the research stage. [00...

AI Technical Summary

Problems solved by technology

Non-contact electroscopes are prone to false alarms because the collected electric field strength is easily disturbed by surrounding live equipment

[0004] Therefore, the high-voltage electroscope in the prior art has shortcomings such as false alarms and refusal to report to the police. Rejecting the alarm can easily cause misjudgment by maintenance personnel and personal safety accidents, while false alarms can delay valuable maintenance time and bring great harm to the country and the people. huge property damage
