Abstract

This paper from four aspects GL312 type circuit breaker are introduced.The first chapter in combination with the development of today's society, tells the story of GL312 circuit breaker in the importance of the high voltage power transmission and distribution and switch;The second chapter according to the function and principle of the circuit breaker, this paper introduces the circuit breaker control circuit operation;The third chapter mainly introduces the function of measurement and control cabinet, and how to implement the "four control" function;The fourth chapter for the design of the secondary loop, mainly for the ac current, voltage circuit and the circuit breaker closing and control circuit.In this thesis is mainly explained the GL312 prevent wrong operation of type SF6 circuit breaker loop and the jump.GL312 is firstly analyzed, the operation of the circuit breaker control circuit, the main circuit breaker "jump" prevention operation circuit is analyzed, emphatically introduces the circuit breaker is how to use the spring operating mechanism to improvement points and perform the reliability, then the operating circuit, signal circuit and trip circuit was introduced in detail;Then introduces the protection of ark of a device and the secondary loop;The last of this thesis design CAD, are: signal part, communication power supply parts, electric current and voltage, isolating switch, high voltage switch relationship between their respective circuit part.

Key words: circuit breaker;anti-jump.目录
