Full-sensing monitoring and patrol inspection operation and maintenance system of distribution network equipment

Abstract

The invention discloses a full-sensing monitoring and patrol inspection operation and maintenance system of distribution network equipment. The switch cabinet monitoring system is used for monitoringthe temperature of key points of the switch cabinet, arc protection and circuit breaker parameters. Distribution line monitoring system: used to monitor the electrical parameters and operating statusof the line, when the line fault occurs, early warning and generation of fault information; Robot monitoring system in power distribution room: it is used to monitor the environmental parameters in power distribution room and patrol the parameters of equipment and instruments; Operation and maintenance system management system: used for on-line panoramic monitoring, statistical analysis and forecast maintenance of distribution network. The switch cabinet monitoring system, the distribution room robot monitoring system and the distribution line monitoring system are all connected with the operation and maintenance system management system through network equipment for exchanging information and control signals. The distribution room and distribution line can be controlled remotely and centrally by the operation and maintenance system management system.

Description

technical field [0001] The invention belongs to the technical field of intelligent perception systems of substations and distribution stations, and in particular relates to a full-sensing detection and patrol inspection operation and maintenance system of distribution network equipment. Background technique [0002] As the foundation of the power grid, power distribution equipment, after being put into operation, will be affected by various internal or external factors such as aging, weather, and human operation, which will degrade the performance of the equipment, causing various failures of the equipment to stop running, and equipment failure to stop running , will bring great harm to the safe and reliable operation of the power grid. Therefore, timely maintenance of equipment has become an indispensable work for daily production management of power grids. However, this process needs to be completed manually. There are many types of distribution network equipment in my co...

Problems solved by technology

However, this process needs to be completed manually. There are many types of distribution network equipment in my country, the number is huge and the distribution is wide, which makes the inspection, maintenance and management of equipment complicated. Therefore, manual inspection and maintenance require high professional quality of personnel. Inspection and maintenance are labor-intensive and inefficient

[0003] In the distribution network system, part of the monitoring system based on the Internet of Things distribution network equipment alleviates the problems caused by manual detection and maintenance, for example: Chinese patent application number is 201711228502.X, application publication number is CN107910957 A , The name of the patent is an intelligent perception system for substations and distribution stations based on the Internet of Things. The patent uses video environment monitoring devices, intelligent distribution transformer core monitoring devices, switch cabinet wireless temperature measurement subsystems, low-voltage branch box voltage and current The transformer temperature collector and reactive power compensation control device monitor the equipment in the power distribution station, which solves the problem of insufficient intelligence and convenience in the existing human-computer interaction in the power distribution station to a certain extent.

However, there are still the following problems: only intelligent monitoring of substations and distribution stations, insufficient perception of the overall distribution network system, and difficulty in realizing the overall operation and maintenance of the distribution network system; secondly, the fixed sensors required for substations and distribution stations The number of installations and instruments is large, a large amount of wiring is required, and the cost is high
