Current status and development trends of power systems
The traditional power distribution system is based on the radial type and is supplemented by a combination of radial type and tree trunk type. Almost all power receiving and feeding cabinets of complete sets of switch cabinets use open circuits. device. This power distribution method not only occupies a large area and requires high investment, but also has low reliability.
At present, the most commonly used ring network cabinets in our country are mainly load switch fuse cabinets and air insulated load switch cabinets. It can not only reduce the area of high-voltage power distribution rooms and lower the floor height, but also the ring network cabinets do not require operating power and do not require special equipment. The control room can further reduce the occupied area, which is more advantageous for power distribution stations in high-rise buildings. The ring network switch cabinet is easy to install and debug, simple to maintain, and easy to realize automatic management of the power grid.
Overview of Microcomputer Comprehensive Protection
The application of ring network cabinets in the development of the power industry is becoming more and more widespread. In view of the compact structure of current ring network cabinets, Jiangxi Huajian Electric Power Industry Company adopts advanced embedded digital signal processors And summarized the successful operation experience of microcomputer protection and measurement and control devices in power distribution stations, and launched a series of microcomputer comprehensive protection devices that can be applied to distribution network automation systems, smart box transformers, smart outdoor switches, smart ring network cabinets, smart outdoor branch boxes, smart outdoor metering and power control device. In particular, it is a high-performance and cost-effective microcomputer comprehensive protection device dedicated to the series of mini ring main unit solid insulation cabinets.
It integrates the latest digital control technology, anti-strong interference technology and fault self-diagnosis software repair technology. With its extremely small maintenance workload, it provides relay protection fault location, monitoring, monitoring, power quality and communication for high-voltage power systems. Provides advanced management capabilities.
