直流接触器触头倒角及中心磁感应强度对电寿命的影响
Effect of Chamfer and Center Magnetic Induction on Electrical Life of DC Contactors
摘要
Abstract
When the sealed DC contactor breaks the load,the splashing of contacts in the arc extinguishing chamber is inevitable.The influence of contact chamfering and center magnetic induction on electrical life is verified by grouping test.The results show that with the increasing of contact center magnetic induction,the total number of breaking load will be increased,but the spattering will also be increased,which will lead to the decrease of dielectric voltage resistance and insulation resistance.The spattering will be decreased with the increasing of contact chamfer,the dielectric voltage and insulation resistance will be increased,but the total number of breaking load will be reduced.关键词
