Ring main unit active inspection system and method

Abstract

The invention provides a ring main unit active inspection system and method, the system comprises a ring main unit, a main station and a terminal device, a signal acquisition module is connected witha wireless communication module, and the signal acquisition module is used for transmitting state information acquired by the signal acquisition module to a processing module of the main station through the wireless communication module; the processing module is connected with the signal sending module through the encryption module, and is used for processing and verifying the received state data,encrypting the data after the verification is passed, and sending the encrypted data to terminal equipment through the signal sending module; and the terminal device is used for decrypting the processed encrypted data after receiving the processed encrypted data, sending a power-off instruction to the ring main unit according to the decrypted data, sending an instruction for verification after setting time to determine that the ring main unit quits operation, and outputting an overhaul task list. Maintenance personnel carry out active maintenance on the corresponding ring main unit through the maintenance task list. Automatic operation is achieved, inspection work is greatly facilitated, the work efficiency is improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to the field of electric power distribution inspection, in particular to an active inspection system and method for a ring network cabinet. Background technique [0002] In order to ensure the safe operation of the distribution network, it is necessary to conduct inspection tests on the distribution ring main unit. The problem that has plagued the distribution inspection department for many years is the remote wireless control of the ring main unit. In the distribution network, the distribution of the ring main unit is large. The transportation inspection department needs to regularly test the control action of the ring network cabinet every year and deal with the abnormal situation of the ring network cabinet in time to avoid power failure caused by equipment failure. However, in the actual maintenance, it is found that there is a large gap between the accuracy of on-site operation and maintenance and the actual remote control op...

Problems solved by technology

However, in the actual maintenance, it is found that there is a large gap between the accuracy of on-site operation and maintenance and the actual remote control operation, resulting in repeated maintenance and invalid maintenance, which wastes manpower and material resources and is easy to leave defects. In order to ensure the correctness of remote control operation, it is necessary to develop an active patrol system The inspection system discovers equipment defects in time, and determines the actual type of defects and arranges work teams for timely maintenance
