Comprehensive monitoring system for low-voltage power distribution station area

Abstract

The invention relates to a comprehensive monitoring system for a low-voltage power distribution station area. The comprehensive monitoring system is mainly technically characterized by comprising station area measuring and monitoring terminals, a monitoring center server, a monitoring center control terminal and station area principal mobile phones, wherein the station area measuring and monitoring terminal arranged in each low-voltage power distribution station area is connected with the monitoring center server through a GPRS/3G (General Packet Radio Service/3rd Generation) network; the monitoring center server is connected with the monitoring center control terminal through an internal network; and the monitoring center server is communicated with the station area principal mobile phones through a mobile communication network. The comprehensive monitoring system is reasonable in design; and the creepage defect of a low-voltage electric network can be found in time for handling rapidly through each station area measuring and monitoring terminal, tripping and power failure accidents are reduced greatly, the power supply reliability is enhanced, the three-phase load unbalance degree of each station area is lowered effectively, the line loss effect of the low-voltage electric network is reduced, the utilization ratios of equipment of the low-voltage electric network, such as transformers are increased, infrared detection, shooting and voice prompting and alarming functions can be realized, and the phenomena of loss of transformers and electric shock damages can be avoided effectively.

Description

technical field [0001] The invention belongs to the field of power grids, in particular to a comprehensive monitoring system for low-voltage power distribution stations. Background technique [0002] At present, the leakage protector in rural power grids often trips due to leakage, which leads to accidents such as power outages. The magnitude of the leakage current of the existing power grid requires manual on-the-spot measurement, which cannot realize the real-time detection function of the leakage level of the power grid, let alone predict the leakage defect of the power grid and deal with it in time. In addition, in rural power grids, transformers are often lost or children stray into live parts, causing economic losses or electric shock injuries. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a comprehensive monitoring system for low-voltage distribution stations with high reliabili...
