- 摘要：
- This paper introduces a new slot type axial magnetic field (AMF) contact. It has lower resistance compared with its counterpart conventional one by introducing a contactbridgethat substitutes for stainless steel support in conventional contact. There is a gap between the contact bridge and contact plate. In close position, the contactbridge is pressed on contactplate by contact force and coil deformation. So current goes throughthecontact bridgeto reachcontactplate directly.Inaninterruptionoperation,thegaprestoreswithcontact force disappearing, whichpushes currentpassingthrough
coils ofthe slot typeAMFcontact. So sameAMFcan be generated as a conventional one. Asa result, short circuit
current interruption tests showed that the interrupting capacity ofthe vacuuminterrupterwith newcontactswas notlessthanthatwithconventional contacts.Resistance of vacuum interrupterwith conventional contactis 10-12pQ
at contact force2000N.It decreasedto 7pQwith the new contact.
