Summary:
Axialmagneticfield (AMF)characteristics ofcoil typeAMFvacuuminterrupters are analyzed by3Dfinite
element method. Sevencontact parametersare taken into accountinthis paper.Analysisresults showthat: (1) Axial
magnetic flux density decreases with increase of contactdiameter, coil height, and gap distance. Axial magnetic
flux density is not sensitive to coil thickness. Sois contact plate material. Axial magnetic flux density is strongly
influenced bywelding of stainless steel plates to contact plate and coil. (2) Phase shift time between AMFand
sourcecurrentdecreaseswithdecreaseofcontactdiameterand increase ofcontact gap. Andit also decreases when
contactmaterial is CuCr5O.(3) Maximumcurrentdensity in coils orcontactplates decreaseswithincrease ofcontact
diameter, coil thickness. And it also decreases when contactmaterialis CuCr25.Sodoesconductorresistance.
