基于模糊综合评判的断路器可靠性状态评估

State Assessment of Circuit-breaker Reliability Based on Fuzzy Comprehensive Evaluation

由于设备制造质量的提高,高压断路器逐渐成为少维护或免维护的设备,为保证供电的可靠性,需密切关注其运行工作状态,确保及时必要的维修工作。利用模糊数学的思想,提出一种模糊综合评判的方法来评估断路器工作状态,将表征断路器工作状态的可靠性参数结合起来,为断路器状态检修工作提供依据。

HV circuit-breaker has gradually become the equipment needing less maintenance or free of maintenance due to the improvement of equipment manufacturing quality,but in order to ensure the reliability of power supply,a close attention to its operating condition is needed to guarantee the necessary maintenance in time.Using the idea of fuzzy mathematics,a fuzzy comprehensive evaluation method is proposed to evaluate the working condition of the circuit-breaker,and the proposed method is combined with the reliability parameters which characterize the working condition of circuit-breaker,which gives a reference for the condition-based maintenance of circuit-breaker.
