Problems solved by technology
The invention uses power carrier communication, but power carrier communication has the following disadvantages: 1. It is blocked by the distribution transformer; 2. There is a large signal loss (10dB-30dB) between the three-phase power lines; 3. The power line has its own inherent pulse Interference requires a large number of peripheral circuits to amplify and filter the signal, which is not suitable for large-scale use; due to the blocking effect of the distribution transformer, when the centralized collector fails, the signal communication in the area is completely interrupted, and there are defects in use

The invention discloses a system and method for detecting the main equipment of a distribution network in a live working state based on power wireless communication. The system comprises a data platform, data concentrators, data collectors and a detector. The method comprises steps that the data collector acquire suspected partial discharge signals; the data concentrators collect the signals collected by different data collectors everyday; the data platform collects the signals collected by different data concentrators everyday; the data platform processes and identifies the signals; if discovering a suspected partial discharge point, the data platform pushes a warning message and notifies a relevant worker; the worker displays the relevant detected information on the detector. The systemand method for detecting the main equipment of a distribution network in a live working state based on power wireless communication can improve the live-working detection efficiency of the distribution network, have fast data processing and transmission speed, ensure the safety of equipment and data, have high image recognition accuracy, can eliminate the interference of error information and cancarry out the live-working detection.
Description
technical field [0001] The invention belongs to the technical field of live detection of distribution network, and in particular relates to a system and method for live detection of main equipment of distribution network based on electric power wireless communication. Background technique [0002] Facing the higher and higher requirements of residents and related enterprises for the power supply reliability of the distribution network, it is necessary to carry out live detection work on the main equipment of the distribution network. By detecting the defects of the equipment during the operation of the equipment, and then plan Arrange for repair or replacement, thereby avoiding interruption of power supply due to sudden equipment failure. [0003] With the economic development and the acceleration of urbanization, the number of equipment in the distribution network is increasing and the distribution is scattered. The existing distribution network live detection workload is ...
