摘要
操作机构及其电控回路是影响高压断路器设备可靠性的主要部件,开关智能化、数字化的发展对于开关机构的可靠性提出了更高的要求,研究模块化断路器机构对于提高开关运行的可靠性具有重要的应用价值。研究了断路器机构的模块化改造方法,提出了断路器机构二次系统的模块化设计方案,包括机构一次部分和二次回路模块化。机构一次部分模块化实现了机构箱整体模块化改进及零部件模块化设计,二次回路模块化将分立的二次元器件集成设计为5个功能模块。研究了一种断路器机构快速更换方法,通过技术手段保证机构输出的一致性,实现不同机构的在线互换。为改造后的断路器机构设计了加速老化试验方法并实施验证,结果表明改造后机构的可靠性满足要求。
The operating mechanism and its electronic control circuit are the main components that affect the reliability of high-voltage breaker.The development of intelligent and digital switches demands higher requirements for the reliability of the switch mechanism.It is of great application value to research on modular circuit breaker mechanism for improving the reliability of switch operation.This paper studies the modularization transformation method of the circuit breaker mechanism,and proposes a modular design scheme of the secondary system of the circuit breaker mechanism,including the primary part of the mechanism and the modularization of the secondary circuit.The modularization of the primary part of the mechanism realizes the overall modular improvement of the mechanism box and the modular design of the components,and the modularization of the secondary circuit integrates the discrete secondary components into five functional modules.A quick replacement method of circuit breaker mechanism is also studied,the consistency of mechanism output is kept by technical means to realize the on-line replacement of different mechanisms.The accelerated aging test method is designed and the modified circuit breaker mechanism is tested with the method.The results show that the reliability of the modified mechanism meets the requirements.
