发明名称 METHOD FOR PRODUCTION OF A POLE PART OF A MEDIUM-VOLTAGE SWITCHING DEVICE, AS WELL AS THE POLE PART ITSELF
摘要 A method for production of a pole part of a medium-voltage switching device, and a pole part are provided. To obviate costly pressure reinforcements at least on the switching contact side of the vacuum interrupt chamber in the area of the mold core, while also achieving an optimum injection-molded result, a compensation ring is positioned, before the encapsulation process, as a separate injection-molded seal on or close to the external circumferential line of a vacuum interrupt chamber cover, between the lower cover of the vacuum interrupt chamber and the mold core. The positioned compensation ring is also encapsulated so as to remain in the encapsulation, and the mold core is then removed.
