예상치 못한 접촉기 오류로 인해 생산이 중단되고 제조 가동 시간과 처리량에 영향을 미칠 수 있습니다. 일반적으로 접촉기의 수명은 제조업체의 수명 테스트 데이터를 기반으로 합니다. 그러나 접촉기 작동 방식과 작동 환경에 따라 접촉기의 작동 수명이 크게 달라질 수 있습니다. 본 논문에서는 DC 코일 전류와 접촉기 전류를 모니터링하여 DC 작동 접촉기의 잠재적인 고장을 예측하는 새로운 기술을 조사했습니다. 접촉기의 상태를 모니터링하기 위해 이 데이터 세트에서 접점 초과 이동, 전기자 풀인 시간 및 코일 전류 차이의 세 가지 매개변수가 파생됩니다. 접점 초과 이동은 접점의 남은 수명에 대한 정보를 제공하고 코일 전류 차이는 잔해로 인한 접점 용접 및 캐리어 걸림을 나타냅니다. 전기자 풀인 시간은 접촉기 폐쇄 속도에 대한 정보를 제공합니다. 프로토타입 접촉기가 제작되었으며 평가를 위해 AC4 테스트가 수행되었습니다. 테스트 결과에 따르면 접촉 초과 이동 매개변수는 접촉기가 고장난 후 얻은 접촉 질량 손실 데이터와 잘 일치하는 것으로 나타났습니다. 파생된 전기자 풀인 시간은 레이저 변위 센서로 측정된 시간과 잘 일치합니다. 정의된 매개변수는 잠재적인 접촉기 고장에 대한 효과적인 모니터링 및 예측을 제공합니다.

Abstract: Unpredicted contactor failure can interrupt production and affect the uptime and throughput of manufacturing. Usually the life of a contactor is based on the manufacturers' life test data. However, due to the way of how the contactor is operated and the environment it is operated in, the working life of a contactor can vary significantly. In this paper, a novel technology has been investigated to predict potential failures of DC actuated contactors by monitoring their DC coil current and contactor currents. Three parameters are derived from this set of data to monitor the health of contactors: contact over-travel, armature pull-in time and coil current differential. Contact over-travel provides information on the remaining life of contacts and coil current differential provides indication of contact weld and carrier jam due to debris. The armature pull-in time provides information on contactor closing speed. Prototype contactors have been built and AC4 tests have been carried out for evaluation. Test results show that the contact over-travel parameter agrees well with contact mass loss data taken after contactors failed. The derived armature pull-in time agrees well with that measured by a laser displacement sensor. The defined parameters provide effective monitoring and prediction of potential contactor failures.
