摘要
Abstract
The objective of this paper is to experimentally determine the coil width of a 3/4 coil-type axial magnetic field (AMF) contact used in 126 kV vacuum interrupters by comparing the duration of diffuse arc mode,duration of intense arc mode and high current vacuum arc behavior.Three types of coil width are tested in the experiment.The coil width of contact type 1,contact type 2 and contact type 3 is 12 mm,14 mm and 16 mm,respectively.Arc current is set as 36 kA(rms) and 40 kA(rms).Arc duration in first current half-wave is set as 3.5 ms and 9 ms.Experiment results show that the duration of diffuse arc mode before current zero of contact type 2 is the longest among the 3 types of contact.The duration of intense arc mode of contact type 2 is the shortest among the 3 types of contact.Besides,with the increase of arc current,the duration of diffuse arc mode before second current zero of each type of contact decreases.Based on the experiment results,the coil width of the 3/4 coil-type contact used in 126 kV vacuum interrupter is determined as 14 mm.关键词
