摘要

高压电力设备中常用的灭弧气体是SF

其具有良好的灭弧性能和绝缘强度。但是

是一种强温室效应的气体

在将来将被逐渐禁用。因此

研究以氟化腈C

N气体为代表的新型环保气体作为SF

的替代气体并分析其灭弧性能

成为了近年的热点问题。电流开断是一种复杂的多物理场耦合过程

研究气体电弧的发展规律对提升断路器的开断能力意义重大。文中主要针对SF

、C

N/CO

不同气体介质的燃弧过程进行了仿真

得到C

N混合气体的温度分布和气压分布与SF

的差异。通过35 kV断路器开断实验

可以解释断路器开断过程中的相关物理现象

并研究C

N/CO

的具体灭弧性能

以判断其对SF

的实际可替代性。最终结果显示

5%C

N+6%O

+89%CO

混合气体在单次分闸以及重合闸工况下都可以成功开断25 k A的短路电流。

Abstract

is a common arc extinguishing gas in high voltage electrical equipment due to its perfect arc extin-guishing performance and insulation strength.However

is a kind of gas with strong greenhouse effect and willbe phased out gradually in the future.Therefore

the study on C

representing new environmental gas as an al-ternati

ve gas to SF

and analysis of its arc interruption performance has become the hot topic in recent years.Cur-rent interruption is a kind of complicated multiple physical coupling process.And the the study of the law of gas arcis of great significance for improving the current interruption capacity of circuit breaker.In this paper

the arcingprocess of such different gas medium as SF

and C

N/CO

is simulated and the difference of temperature and pres-sure distribution between C

N gas mixture and SF

is obtained.The related physical phenomena in the interrup-tion process of the circuit breaker can be explained through interruption experiment of 35 kV circuit breaker.Thespecific arc interruption performance of C

N/CO

is studied to judge its actual substitution for SF

.It is shown bythe final result that 5%C

N+6% O

+89%CO

gas mixture can successfully interrupt short circuit current at 25 k A inboth single interruption and re-closing interruption conditions.
