Abstract

The invention is concerned with computer protecting monitor device, belonging to power system auto-control process field and it is fit to form the intelligent terminal device of integration automatic system with 35 KV and less. It relates to CPU, cabinet, plug-in board and operation system. The plug-in board relates to power supply, main board, simulation/ transformer board, relay board, keyboard/ display. The said operation system is embedded task module. The task module relates to protect unit, test unit, control unit, monitor unit, communication unit, fault recorder unit and accident recorder unit. This equipment of invention can be adjusted easily with high intelligent integration and it is fit for installing on switchboard or grouping screen together. Each part fixes alone to disperse heat with strong anti-jamming ability to be replaced.

Description

technical field [0001] The invention relates to a microcomputer protection measurement and control device, which belongs to the technical field of electric power system automatic control. It can be installed on a switch cabinet on the spot or collectively assembled into a screen, and is especially suitable for forming an intelligent terminal device of a comprehensive automation system for power grids of 35KV and below. Background technique [0002] In the high, medium and low voltage power systems, more and more integrated digital automation devices are used, and there is a trend of integration of relay protection, operation control and monitoring in the world. ABB, GE, SIEMENS and other large foreign companies have launched A series of representative products of comprehensive digital protection. Domestic representative companies include NARI, NAZI, Sifang, Dongfang Electronics, Xu Ji, etc. [0003] The current comprehensive automation system in China is divided into two ty...
