Abstract: 1,110,123. Protective arrangements. J. STONE & CO. (DEPTFORD) Ltd. 19 April, 1966 [26 April, 1965], No. 17401/65. Heading H2K. An arrangement for protecting semi-conductor apparatus comprises a thyristor 3 connected across the supply to the apparatus and a Zener diode 4 or other device connected to the apparatus and responsive to overvoltage conditions to apply a control signal to the thyristor to render it conducting to short-circuit the apparatus. A fuse 7 is then blown, or an automatic circuit-breaker is operated, by the shortcircuit current to interrupt the supply to the apparatus. As shown, the Zener diode 4 is connected in series with a resistor 5 across the supply to the apparatus 1 and, in the event of overvoltage, conducts. The voltage across the resistor 5 is applied to the gate of the thyristor 3 through a variable resistor 6 to render the thyristor 3 conducting, a slight delay being provided by capacitors 9 to prevent undesired operation under transient conditions. Should the supply be alternating current, then diodes 10, 11 are connected as shown. Figs. 2 and 3 (not shown), illustrate the application of the arrangement to the field circuits of a D.C. generator and an alternator. By providing a further Zener diode 4 and resistor 5 the arrangement may be connected to provide overcurrent protection. Reference has been directed by the Comptroller to Specification 1,005,261.

Abstract: 1423748 Protective arrangements SPRECHER & SCHUH AG 13 April 1973 [23 May 1972] 18010/73 Heading H2K In an electronic circuit for protecting a motor M from overload, the heating of the motor is simulated by a capacitative storage circuit 4 charged by a current which is a function of the motor current, a threshold circuit 5 becoming operative, when the voltage of the circuit 4 exceeds a predetermined value, to initiate interruption of the motor circuit. The circuit 4 includes separate capacitors to simulate the thermal capacities of the motor winding and motor stator and separate resistors to simulate their heat transfer to the cooling air. The charging current may be derived from a circuit 3 as the square of the motor current and long time delays may be provided by the use of a clock generator controlling the application of the charging current to the circuit 4 in pulses, Fig. 2 (not shown). In further arrangements, Figs. 3 and 4 (not shown) the charging current is proportional to the motor current and the pulse frequency is also proportional to the motor current so that the effective charging current is proportional to the square of the motor current. Fig. 5 (not shown) illustrates a transistor circuit for carrying out the invention.
