Abstract

The invention provides a wireless communication measuring system for current of a build-in arrester, which is used for measuring the current or the voltage flowing through arrester cores. The system mainly consists of multiple measuring transducers, a relay transducer, a central controller and an upper PC (Personal Computer). The system is characterized in that the measuring transducers which are respectively placed inside multiple arrester cores are in series connection with resistor discs inside the arrester, and the measuring transducers send the measured result on the current flowing through the cores inside the arrester to the relay transducer through a wireless transmission module for signal conditioning. The measuring transducers provided by the invention are built inside the arrester cores, measured parameters are all information related to the interior of the arrester, and the interference of outside information is avoided.

Description

technical field [0001] The invention relates to a built-in lightning arrester current wireless communication measurement system, which belongs to the field of lightning arrester current measurement. Background technique [0002] According to the standard requirements of GB11032 "Metal Oxide Surge Arresters for AC Systems", zinc oxide resistors should be subjected to artificial accelerated aging tests. Before the test, the amplitude of the applied aging voltage must be determined according to its voltage distribution. Therefore, measure the voltage distribution of the arrester. , is the key to determine the amplitude of the aging applied voltage. In addition, according to the online monitoring system for electrical equipment launched by the State Grid Corporation of China in recent years, the on-line monitoring of the arrester also needs to measure the internal current of the arrester. At present, the system for measuring the internal current of the arrester basically adopts ...
