摘要

随着高压断路器开断电流不断增大，要求配用的弹簧操动机构应具有更大的操作功。在机构合闸过程中，冲击变大，合闸保持结构的稳定性降低，偶尔会出现机构合闸后立即分闸的“空合”现象。文中首先对CT26弹簧操动机构合闸保持结构进行了研究，通过采取增大机构合闸过冲量、加快合闸保持掣子复位速度、增大滚子与分闸掣子扣接区域等措施，对合闸保持结构进行了设计改进，并通过试验进行了验证。最终，消除了操动机构的“空合”现象，提高了断路器动作的可靠性。

Abstract

With the increase of interruption current of high voltage circuit breaker

the equipped spring operating mechanism is required more operating power. During the closing process of the mechanism

the impact increases

the stability of the closing holding structure decreases and occasionally the“idle closing”phenomenon of immediate opening after the closing of the operating mechanism occurs. In this paper

the closing holding structure of the CT26spring operating mechanism is studied firstly. The design of the closing holding structure is improved by adopting such measures as increasing the closing overshoot of mechanism

speeding up the resetting speed of the closing holding latch as well as increasing the buckling area of the roller and the opening latch

and is verified by way of test.Eventually

the“idle closing ”phenomenon of of the operating mechanism is eliminated and operation reliability of circuit breaker is improved
