Abstract

An encapsulated medium-voltage switching cell which is filled with insulating gas, has a sealed enclosure (1) filled with insulating gas, has at least one first stationary contact (6) which is insulated from the enclosure, has at least one second contact (10) which is at a distance therefrom, is electrically conductively connected to the enclosure and is earthed, has at least one third contact (13) which is arranged at a distance from the two contacts (6, 10), has at least one contact bolt (15) which is guided essentially in a straight line in an insulated manner in the enclosure and is electrically conductively connected (16, 36) to the third contact (13) at one end, has at least one switching shaft (18) which is mounted in the enclosure such that it can rotate, is electrically insulated and moves the contact bolt (15) and the electrical connection (16, 36) to the third contact (13), has a crank arm (19), and has at least one approximately vertical guide (20) which is hinged thereon and has a hinged connection (17) to the contact bolt (15), the contact bolt (15) making contact with the first contact (6) in the first position of the switching shaft (18) and the electrical connection (16, 36) making contact with the second contact (10) in the second position of the switching shaft (18), and none of the contacts (6, 10) making contact in the intermediate, central position. <IMAGE>
