Research on Ablation and Material Properties of Arc Extinguishing Nozzles for Large Capacity Circuit Breaker
以大容量灭弧喷口为研究对象,对不同氮化硼(BN)填充物含量的灭弧喷口进行开断烧蚀试验,得到了BN填充物含量对喷口烧蚀量的影响规律.其次,利用有限元对5%BN填充物含量的灭弧喷口进行温度场仿真计算,研究烧结工艺对灭弧喷口物理和性能的影响,并得到最优的烧结工艺曲线.利用最优烧结工艺制造不同BN填充物含量的灭弧喷口,并对其拉伸强度、断裂伸长率、击穿强度等参数进行测试,得到填料含量对灭弧喷口性能的影响规律.为后续大容量断路器用灭弧喷口配方选择提供了基础数据和理论支撑.
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.
