AI Technical Summary

Technical Problem

The prior art is difficult to accurately monitor the life of DC contactors, resulting in large errors in life estimation and the inability to accurately monitor the life of DC contactors.

Method used

By obtaining the working status of the DC contactor, determining its current current when the disconnection command, calculating the change in performance indicators, and adjusting the change in performance indicator correction coefficients, and finally determining the target performance indicators and actual service life of the DC contactor.

Benefits of technology

The DC contactor life estimation error is reduced, and the DC contactor life is accurately monitored, solving the problem of difficulty in accurately monitoring the DC contactor life.

Abstract

The present invention discloses a method, device, storage medium and processor for determining the performance of a DC contactor. The method comprises: obtaining the working state of the DC contactor; determining the current current of the DC contactor when responding to a disconnection instruction based on the working state; determining the performance index change of the DC contactor based on the current current, wherein the performance index change is used to indicate the reduction range of the performance index of the DC contactor relative to the rated performance index of the DC contactor; adjusting the performance index change based on the performance index correction coefficient of the DC contactor; determining the target performance index of the DC contactor based on the adjusted performance index change and the initial performance index, wherein the initial performance index is used to indicate the initial service life of the DC contactor, and the target performance index is used to indicate the actual service life of the DC contactor. The present invention solves the technical problem that it is difficult to accurately monitor the life of a DC contactor.
