The invention discloses a live detection system and method of a power distribution network main device. The system comprises a data platform, a data concentrator, a data collector and an inspection instrument, and the method specifically comprises the steps that a data collector collects the suspected partial discharge signals through an intelligent sensor and stores the signals; the data concentrator collects the suspected partial discharge signals collected by different data collectors at least once every day through a power wireless private network; the data platform collects the suspectedpartial discharge signals collected by different data concentrators at least once every day through the power wireless private network; after the data platform processes the suspected partial discharge signals, whether the suspected partial discharge signal is a partial discharge signal is identified through a certain judgment strategy; and if a suspected partial discharge point is found, the dataplatform pushes an alarm through an electric power wireless private network and notifies the related workers through a short message platform, and the workers display the related detected informationthrough the intelligent inspection instrument.
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. Background technique [0002] With the development of the economy 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 large and the working points are scattered, which consumes a lot of manpower and material resources; the effect and efficiency of live detection need to be improved. [0003] According to the "Technical Specifications for Live Detection of Electric Power Equipment (Trial)" document issued by the State Grid Corporation of China, live detection methods include: high-frequency partial discharge detection, infrared thermal imaging, ultrasonic signal detection, ultra-high frequency partial discharge d...
