微机“五防”装置的应用与管理

Application and management of microcomputer-based misoperation-proof lockout device

微机“五防”装置以其技术先进、功能齐全、运行可靠、维护方便等优点, 已成为电力系统“五防”的主流装置, 为此, 介绍了微机“五防”装置在广电集团潮州供电分公司的应用及管理。应用微机“五防”装置后, 在变电站防止倒闸误操作上效果良好。但是, 单纯依靠“五防”装置并不能完全防止误操作事故的发生,加强对“五防”装置的管理是保证倒闸操作安全、防止误操作的关键。

Characterized by advanced technique,complete functions,reliable operation and convenient maintenance,the microcomputer-based misoperation-proof lockout device has become the mainstream device for preventing electric misoperation in power system. This paper describes the application and management of the said device in Chaozhou Power Supply Branch,GPG. It is indicated that misoperation failures can not be completely avoided solely depending on the device though it is efficient in preventing switching misoperation in substations,and what counts is to strengthen its management.
