Title: Improvements in or relating to overvoltage protective systems
IPC: H02H7/06
Filed: 1951-02-16
Abstract: 698,435. Protective cut-out arrangements. BENDIX AVIATION CORPORATION. Feb. 16, 1951 [Feb. 23, 1950], No. 3861/51. Class 38 (v) In an overvoltage protective arrangement for a plurality of parallel-connected D.C. generators, each generator is protected by means responsive to the voltage across the associated field winding and means responsive to the direction of current in an equalizer connection between the generators. In Fig. 2, each generator 40, 40A has an overvoltage protector 57, 57A similar to that of Specification 653,584 and a control equipment 50, 50A of the character described in Specification 641,787, [Group XXXV]. In each protector 57, 57A, contacts controlling the various circuits are held closed against the bias of a spring 99 by a latch 96 which may be electromagnetically released by windings 101, 106 (101A, 106A). Each winding 101, 101A is connected across the shunt field winding 41 of the associated generator by means of conductors 102, 103 and contacts 93, 94 of the protector. The windings 106, 106A are connected in series in an equalizer circuit extending from the junction of the armature and interpole connections of one generator to that of the other generator through conductors 107, 108 and contacts 104, 105 of both protectors. If a generator, for example generator 40, tends to generate an excess voltage it will take more than its share of the load, so causing current to flow in the equalizing connection. The direction of this current is such that the winding 106 assists the winding 101, whilst the winding 106A opposes the winding 101A. Thus the latch 96 is withdrawn allowing the contacts of protector 57 to open and disconnect the generator 40 and its associated circuits, the opposing action of the winding 106A preventing the tripping of the protector 57A. Specification 608,508, [Group XXXV], also is referred to. Reference has been directed by the Comptroller to Specifications 641,671 and 644,437.
