Patent number: 4453054Abstract: Contact apparatus for vacuum switches. It includes a fixed and a movable contact bolt. Each has an end portion with an end face facing the other. Two disc-shaped substantially identical contacts surround the end portion of each of the contact bolts, and each of the contact discs have an annular inner hollow space formed therein which define side walls which face each other and have closed inner and outer side wall surfaces. The contact discs have side walls facing away from each other and each is fastened to a corresponding one of the contact bolts. The end face of each of the end portions are located at a distance from the inner side wall surface of the corresponding one of the contact discs which defines a gap therebetween. The side walls of the contact discs have slots formed therein which are extended in the same direction, and has coil turns placed between the slots at a given slope which produces an axial magnetic field at the moment the contacts break.Type: GrantFiled: August 23, 1982Date of Patent: June 5, 1984Assignee: Siemens AktiengesellschaftInventors: Gerhard Peche, Gunter Bialkowski

Patent number: 4438307Abstract: The invention relates to a vacuum switch with cup-shaped switch contact components having an obliquely slit contact carrier and mounted unslit contact ring. The contact carrier consists of copper with or without additional chromium and the contact ring consists of a chromium-copper matrix with or without additions. The electrical conductivity changes rapidly from the contact carrier to the contact ring by a factor of at least 3. The invention is useful for high power vacuum switches.Type: GrantFiled: March 31, 1983Date of Patent: March 20, 1984Assignee: Siemens AktiengesellschaftInventors: Hans-Joachim Lippmann, Gerhard Peche, Hans Bettge

Patent number: 4306129Abstract: A low voltage contactor switch has three simultaneously actuated pairs of contacts each of which consists of a movable and a fixed contact, with contacting occurring in a single evacuated area within a vacuum tube for minimizing oxidation of the contact surfaces and thereby increasing contact life. The contacts are connected to terminals which extend through walls of the vacuum tube in air tight fashion with actuation of the movable contacts being undertaken with the use of an air-sealed bellows. Each contact pair may be individually isolated by a cylinder within the evacuated area surrounding each contact pair as well as by a Y-shaped plate dividing the evacuated area into three chambers.Type: GrantFiled: May 1, 1980Date of Patent: December 15, 1981Assignee: Siemens AktiengesellschaftInventors: Guenter Bialkowski, Gerhard Peche

Patent number: 4243859Abstract: An improved vacuum switch has slotted, flexible, discus-shaped contact discs attached to the current carrying contact bolts. In the open circuit case, a gap exists between each contact bolt and its corresponding contact disc and between the two discs. In the closed circuit case, the contact bolts drive the contact discs against one another, slightly deforming the contact discs, resulting in a low resistance current path. As the switch starts to open, the contact bolts first separate from the adjacent disc surfaces. As the switch opens further, any arc that ignites exists only between the contact discs. Tangential slots in the contact discs guide the arc toward the center of the contact discs. The flexible discs assume their previous undistorted shape when the switch has opened.Type: GrantFiled: September 11, 1978Date of Patent: January 6, 1981Assignee: Siemens AktiengesellschaftInventor: Gerhard Peche

Patent number: 4091436Abstract: A knob type surge voltage arrester has electrodes with conical or semi-circular shape. A coating consisting of electrically conductive material (an ignition aid) is provided on the insulating member. The conductive coating on the insulating body is positioned at a level corresponding to the center of the discharge path defined by active electrode surfaces of the electrodes. The spacing of the active electrode surfaces from one another is smaller than the spacing of the active electrode surfaces relative to the coating.Type: GrantFiled: October 26, 1976Date of Patent: May 23, 1978Assignee: Siemens AktiengesellschaftInventors: Gerhard Lange, Gerhard Peche

Patent number: 3989985Abstract: A surge voltage arrester includes a gas-tight housing in which electrodes are arranged opposite one another so as to form a gap, and are inserted into the ends of a tube-shaped insulating body on the inside of which at least one strip of electrically conductive material, an ignition strip, extends over a part of the length of the tube commencing from one electrode toward the other electrode. The strip of electrically conductive material extends beyond the gap and the elements of the arrester are relatively disposed such that the distance of the end of the strip of electrically conductive material to the other electrode is greater than the gap between the electrodes.Type: GrantFiled: July 31, 1974Date of Patent: November 2, 1976Assignee: Siemens AktiengesellschaftInventors: Gerhard Lange, Gerhard Peche

Patent number: 3979646Abstract: A surge voltage arrester having a gas-tight housing includes a pair of electrodes arranged at a distance opposite one another and with their active surfaces facing one another. The electrodes are inserted into respective ends of a tubular insulating body which carries at least one coating of electrically conductive material on the inner surface thereof extending over a portion of the tube length, the coating of electrically conductive material defines at least the envelope of a surface whose normal is approximately at right angles to the longitudinal axis of the surface voltage arrester. The coating of electrically conductive material may be punctiform circular, oval, triangular or polygonal. The coating may also be a semiconducting material, rather than a conductive material.Type: GrantFiled: October 9, 1974Date of Patent: September 7, 1976Assignee: Siemens AktiengesellschaftInventors: Gerhard Peche, Gerhard Lange, Dieter Grueneberg
