Current status and development trends of power systems
The traditional power distribution system is mainly radial type, supplemented by a combination of radial type and tree trunk type. Almost all power receiving and feeding cabinets of complete sets of switch cabinets are Use circuit breakers. 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 switches + fuse cabinets. Air insulated load switch cabinets can not only reduce the area of high-voltage distribution rooms and lower floor heights, but also the ring network cabinets do not require operating power. , no special control room is required, and the occupied area can be further reduced, 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
Ring network cabinets are increasingly used in the development of the power industry. In view of the compact structure of current ring network cabinets, Jiangxi Huajian Electric Power Industry Company uses advanced embedded digital signals processor, 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, which can be applied to distribution network automation systems, smart box transformers, smart outdoor switches, smart ring network cabinets, and smart outdoor branch boxes. Intelligent 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, power quality and communication for high-voltage power systems. etc. provide advanced management capabilities.
