| 中文摘要:目前国内外关于断路器的状态检修均采用计划停电的模式，存在不能及时发现断路器存在的潜伏性缺陷的缺点，从而导致断路器故障引起的电网事故。研制了由机械振动测量终端、电场强度测量终端、回路电流测量终端以及智能诊断模块4套组件构成的断路器故障预警装置并开发了由健康评估、智能定级2个模块组成的断路器健康状态量化评估系统。对研制的故障预警装置和健康状态评估系统进行了现场验证，结果表明：所提故障预警装置首次实现了运行状态下高压开关振动、电场以及回路电流信号的非侵入式融合采集，大幅降低了测量装置安装工艺复杂度和安装风险，实现了断路器3类17种故障的精准预警；开发的健康状态量化评估系统实现了断路器近远期健康度的实时评估，降低了断路器运检成本。 |

| Abstract:At present， the Condition-based Maintenance （CBM） of circuit breakers widely adopts the planned power outage mode both at home and abroad， therefore there exist possibilities of failure to detect the latent defects of the circuit breaker in time， which results in power grid accidents caused by circuit breaker failures. To this end， we invented a circuit breaker fault warning device composed of mechanical vibration measurement terminal， electric field strength measurement terminal， loop current measurement terminal and intelligent diagnosis modules， and developed a circuit breaker health status quantitative evaluation system consisting of health evaluation and intelligent grading modules. The field verification of the device and system was conducted and the results suggest that the invented fault early warning device of circuit breakers can successfully realize the non-invasive fusion collection of high-voltage switch vibration， electric field， and circuit current signals during operation and greatly reduce the complexity and installation risk of the installation process of the measuring equipment， and realize the early warning of 17 kinds of faults in 3 categories of circuit breakers. The developed system realizes real-time evaluation of the short-term and long-term health of circuit breakers and reduces the cost of circuit breaker inspection. |
