Description

technical field [0001] The invention relates to a current detection and transmission device, in particular to a remote wireless communication transmission device and method for current information based on distribution network lines. Background technique [0002] At present, the measurement of the line current of the distribution network can usually only be measured at the outgoing end of the line, while the current measurement in the middle of the line, its end, and each branch of the line is difficult due to the lack of power supply and the installation of measuring equipment on the line. Various factors such as the lack of remote wireless communication equipment that can transmit the current information of the line to the background software of the substation make it difficult to perform these measurements. So far, no current measurement in the distribution network line and its various branch lines has been found. device. Due to the lack of current detection devices suit...
