Abstract
The objective of this research is to compare mounted angles between a pair of 2/3 coil-type AMF electrodes in a 126 kV single-break vacuum interrupter.Three kinds of mounted angles are investigated,which have 0°,30°and 60°slot shift between a pair of contact plates,respectively.A comparison of the mounted angles is made based on the distribution of axial magnetic flux density,the AC and DC resistance,the anode discharge mode,and the contact erosion pattern.The axial magnetic flux density,both in the intermediate plane of the electrode gap and on the contact plate under each mounted angle case is compared.The AC and DC resistance for each case are also analyzed.A high-speed Charge Coupled Device (CCD) camera is used to record the arc discharge mode under different mounted angle cases.After 6 interruptions with 40 kA arcing current,the contact erosion conditions with different mounted angle cases are compared.The simulation and experiments all show that when the mounted angle is 30°,the electrode has the smallest resistance and the maximum effective axial magnetic,and it exhibits the best current loading and breaking performance.关键词
