Abstract

804,101. Switching systems for consumption apparatus. YOUNG, G. S. July 15, 1955 [July 19, 1954], No. 20564/55. Class 38 (4). To prevent overloading of a feeder 10 supplying a number of premises, such as 22, 24, 26, a current transformer 62 is provided in the feeder and is arranged to interrupt, or effect a voltage reduction in the supply to, auxiliary load circuits 40, 42 at each of the premises when the current in the feeder exceeds a predetermined value, the main load circuits 36, 38 of the premises continuing to receive normal supply. As shown, the three premises are supplied through a common step-down transformer 12 and the main circuits 36, 38 are fed, respectively, from the two halves of the centre-tapped secondary winding of the transformer. The auxiliary circuits 40, 42 are supplied over contactors, such as 44, 46, 48, the operating coils of which are controlled over a two-way thermal switch 54, 58, 60 responsive to a heater 64 energized by the current transformer 62. Three different contactor arrangements are shown for the three premises, each arrangement providing for the circuits 40, 42 to be supplied at full voltage during normal loading of the feeder, but . when the loading reaches a value sufficient to operate the thermal switch, circuit 42 is interrupted and voltage supplied to circuit 40 is reduced by connecting that circuit to a different tapping of the supply transformer. In the case of premises 26 the circuits 40, 42 are fed through an additional tapped transformer 39. An overriding control cam 66, driven by a synchronous motor 68, may also be provided for operating the thermal switch independently of the feeder current at predetermined times and for predetermined periods.
