集成电路保护装置时间电路的研制

Development of the Time-circuit in Integrated circuit Relay protection Sets

“水电站集成电路成套保护装置的研制”是我们承担的９４年河南省重大科技攻关项目，该装置已投入试运行。本文介绍我们研制的这套保护装置中的时间电路的构成原理、动作特性和应用范围。

evelopment of integrated circuit relay protection sets for hydropower stations″is one of the l994 Henan Major Research Projects.This project is undertaker by us,and the sets have already operation under test.The paper introduces the structure principle,operating characteristic and applicahility of the time-circuit with is applied to integrated circuit relay protection sets.
