大容量断路器用灭弧喷口的烧蚀及材料性能研究
Research on Ablation and Material Properties of Arc Extinguishing Nozzles for Large Capacity Circuit Breaker
摘要
Abstract
The high-capacity arc extinguishing nozzle is taken as the research object,the breaking and ablation tests are firstly conducted on arc extinguishing nozzles with different boron nitride(BN)filling content,and the in-fluence of BN filling content on the ablation amount of the nozzle is obtained.Then,the temperature field simulation calculation of the arc extinguishing nozzle with 5%BN filling content is conducted by using finite element method to study the influence of sintering process on the physical and performance of the arc extinguishing nozzle,and the op-timal sintering process curve is obtained.The optimal sintering process is used to manufacture arc extinguishing nozzles with different BN filler contents,its such parameters as tensile strength,fracture elongation,breakdown strength are tested and the influence of filler content on the performance of arc extinguishing nozzles is obtained.This research has provided basic data and theoretical support for the selection of arc extinguishing nozzle recipe for subsequent high-capacity circuit breaker.关键词
