Wireless rapid detection system and method for potential and temperature distribution of lightning arrester

Abstract

The invention belongs to the technical field of detection of the health status and voltage equalization of arresters before they are put into operation in the electric power industry, and in particular relates to a wireless rapid detection system and method for potential distribution and temperature distribution of arresters, which are suitable for rapid detection of the health status and voltage equalization of arresters before they are put into operation. detection. The present invention consists of three parts: a test probe, a wireless receiver and a remote computer; among them, an arrester valve plate is arranged inside the arrester jacket, and the test probes are inserted between two groups of arrester valve plates at intervals to complete the arrester of each height. Test the distributed potential of the valve plate; each test probe is connected to the wireless receiver through a wireless connection, and the wireless receiver is connected to a remote computer through a USB cable. The invention can greatly shorten the debugging and maintenance time, ensure the safe and stable operation of the lightning arrester, ensure personal safety, improve the detection efficiency, and shorten the system maintenance cycle. It can also improve the accuracy of test data, has strong practicability and pertinence, and has good application value.

Description

technical field [0001] The invention belongs to the technical field of detection of the health status and voltage equalization of arresters before they are put into operation in the electric power industry, and in particular relates to a wireless rapid detection system and method for potential distribution and temperature distribution of arresters, which are suitable for rapid detection of the health status and voltage equalization of arresters before they are put into operation. detection. Background technique [0002] In recent years, the power system attaches great importance to the operation performance of the surge arresters that have been widely used in the power grid. AC non-gap metal oxide arrester, hereinafter referred to as arrester. Due to its excellent electrical performance, it has been widely used in systems since the 1980s, replacing traditional silicon carbide (SiC) arresters. [0003] Whether the potential distribution of the arrester is reasonable or not ...

Problems solved by technology

The optical fiber-current method uses optical fiber to carry out wired data transmission. The disadvantages are that a set of optical receivers has limited measurement points, poor scalability, heavy cable laying workload, and short battery life in the measurement probe. When testing with only test points, you can only repeatedly view the waveform of a single channel, which is very difficult

Since it takes time to switch the test channel, if the power grid f
