Abstract

A 252kV High Voltage SF6 circuit breaker (HV SF6 CB) is taken as an example in this paper, CC method and Wolf algorithm are applied to identify the chaotic characteristic of the electric field during the breaking process, and it is shown that the chaos phenomena exists in the variation of the electric field strength, especially each observation points exist chaos. And the distribution of the chaotic characteristic in the electric field has the consistency and uniformity feature. Compared with the gas flow characteristic during the breaking process, the prediction of the discharge possibility and insulation weakness is found.

高压SF6断路器分断过程混沌分析第一部分:灭弧室电场混沌
本文以252kV高压SF6断路器(HV SF6 CB)为例,应用CC法和Wolf算法对开断过程中电场的混沌特性进行识别,结果表明,电场强度的变化中存在混沌现象,特别是各观测点存在混沌现象。混沌特性在电场中的分布具有一致性和均匀性。通过对断口过程中气体流动特性的比较,得出了对断口放电可能性和绝缘缺陷的预测。
