突变理论在高压断路器运行状态模糊综合评判中的应用

Fuzzy Comprehensive Evaluation of Operating Condition of High-voltage Circuit Breakers Based on Catastrophe Theory

根据目前国内外高压断路器的检测现状以及高压断路器状态评估方法,应用突变理论对高压断路器的复杂系统进行多层目标分解,建立事故潜势数学表达式来反映故障发生的本质特征和机理,对断路器状态进行模糊综合分析与评判,为高压断路器运行状况的综合评价提出了一种新思路。

Based on the status quo of condition maintenance and some condition evaluating ways of the high-voltage circuit breaker（HVCB） at home and abroad, catastrophe theory is adopted to divide the complex system of HVCB into some subsystems according to each factor＇s inherent stratification link, and a mathematical expression of the accident potentiality is set up. It reflects the essential characteristic and mechanism of the accident occurrence and enables fuzzy, comprehensive and dynamic evaluation of HVCB condition. It provides a new way for evaluating the condition of HVCB.
