摘要:

针对1 500 V直流塑壳断路器折叠式灭弧室气道参数对其灭弧性能影响特别明显的情况,对其气道结构进行多参数设计,并对其灭弧性能开展多目标优化。以电弧电压上升时间和峰值电压为优化目标,结合正交试验方法对折叠式灭弧室开展仿真分析。优化结果显示:对比原设计方案,引弧桥折弯角度增大、栅片数量减少、排气孔数量增多及栅片组-挡气板距离增大,有利于加快电弧转移并提高电弧电压;优化后断路器的电压上升时间缩短22.7%,峰值电压提升10.7%,整体灭弧性能显著增强。研究结果可为高电压直流塑壳断路器灭弧室相关设计提供参考。

Abstract:

Aiming at the significant influence of air duct parameters on the arc extinguishing performance of the folded arc extinguishing chamber for 1 500 V DC molded case circuit breakers, multi-parameter design of the air duct structure and multi-objective optimization of its arc extinguishing performance are performed. Taking the arc voltage rise time and peak voltage as optimization objectives, simulation analysis of the folded arc extinguishing chamber is carried out using the orthogonal test method. The optimization results show that compared with the original scheme, increasing the bending angle of the arc guide bridge, reducing the number of grid plates, increasing the number of exhaust holes, and enlarging the distance between the grid plate group and the gas baffle are conducive to accelerating arc transfer and increasing the arc voltage; after optimization, the voltage rise time of the circuit breaker is shortened by 22.7%, the peak voltage is increased by 10.7%, and the overall arc extinguishing performance is significantly enhanced. A reference is provided for the design of arc extinguishing chambers in high-voltage DC molded case circuit breakers.

Key words: DC molded case circuit breaker, folded arc extinguishing chamber, arc extinguishing performance, air duct parameters, simulation analysis
