测量断路器合分时间的必要性

The Necessity of Checking the CO Time of Circuit-Breakers

通过分析断路器合分时间不合格可能出现的故障 ,探讨了合分时间不合格的原因 ,鉴于合分时间是断路器的一项重要技术指标 ,建议定期对其进行检测。

Based on the study of the accidents due to anomalous CO time of circuit-breakers, the reason of the anomalous CO time are discussed, and periodical testing of the CO time is suggested in this paper.
