Filed: 1946-07-23
Abstract: 632,843. Electromagnetic switches sparking preventing in switches. KESSELRING, F. July 23, 1946, No. 7679/49. Convention date, Aug. 7, 1945. Divided out of 632,794. [Class 38 (v)] A current limiter or impedance shunted switch has a number of electromagneticallyactuated moving contact members connected in series, the arrangement being such that the con - tacts separate at not more than 10<SP>-4</SP> seconds after the initiation of a short circuit. The movable contact members 52 which also serve as armatures, are spring-biassed into engagement with fixed contacts 53. Each movable and fixed contact member is connected to a tapping point on a liquid-immersed impedance 57 so that each point of interruption is individually shunted. Immediately after the initiation of short-circuit conditions the coil 51 of the electromagnet 50 is energized sufficiently to turn the members 52 to insert the impedance 57 into the faulty circuit. The switch may be arranged so as to reclose the circuit automatically on the reduction of the fault current or it may be associated with a series disconnecting switch. The impedance may be a non-inductive resistance of a material having a high temperature coefficient such as soft iron. Alternatively condensers may be used and it is dated that their capacities may be reduced by automatic means as the contacts separate. The Specification sets out the theoretical considerations for the above construction and gives the dimensions of the contact member 52.
