Definitions

  • the efiective value of the resistor is determined by the ratio between the intervals of time during which the resistor is short circuited and the intervals of time during which the short circuit is removed.
  • a direct-current generator having an armature winding I, connected to supply circuit conductors 2 and 3 and a field winding 4 connected between these conductors in series with a field controlling re- J sistor 5.
  • Means for controlling the field excitation is provided comprising a primary relay 8 having a winding 1, one terminal of which is connected to the supply conductor 2 and the other terminal of which is connected through a control circuit resistor 8 to the supply conductor 3.
  • the primary relay 6 also comprises a core 12 and an armature l3 carrying a movable contact member II that is adapted to engage a fixed contact member ii.
  • the armature i3 is biased by a spring It to a contactengaging position and upon a predetermined energization of the core l2, sufiicient to oppose the pull of the spring IS, the armature is moved to a circuit-interrupting position.
  • a secondary relay Il may be provided having a core l8 and an armature i9 carrying a movable contact member 2i that is adapted to engage a fixed contact member 22 to close a circuit through conductors 23 and 2
  • a spring 25 is provided for biasing the armature l9 to a circuit interrupting position, the armature being moved to a circuit closing position by the magnetizing influence of the core it upon engagement of the primary relay contact members H and ii to complete a circuit from the source of energy 26 through the secondary relay winding 21.
  • An energy storing device illustrated as a condenser 28, is connected between a junction point p 29 in the field winding circuit and a junction point 30 in the primary relay control circuit.
  • the junction point 29 lies between the generator field winding 4 and the field controlling resistor 5, and the junction point 30 is between the primary relay winding I and the control circuit resistor I.
  • the energization of the primary relay core by the winding 1 is a measure of the voltage between the supply conductors 2 and 3. If the voltage between conductors 2 and 3 falls below the desired value, the pull of the spring it will be greater than the decreased pull on the relaycore caused by energization thereof by the winding 1 and will efifect the engagement of the primary relay contact members It and I5. This causes operation of the secondary relay I! to its circuit-closing position to shunt the control resistor 5 from the field winding circuit and apply a voltage thereto corresponding to the voltage between the supply conductors 2 and 3.
  • the increase in voltage applied to the generator field winding causes the voltage output from the armature winding I to increase, thus increasing the voltage between supply conductors 2 and 3 and the energization of the primary relay winding 1, which upon a predetermined value of generator voltage, will move the armature l3 against the bias of the spring I to separate the contact members it and I5, thus causing the deenergizationof the secondary relay I! to interrupt the circuit through the relay contact members 2
  • This intermittent vibratory action conitinues in a well-known manner to alternately shunt the control resistor 5 from the field winding circuit and reintroduce it into the field winding circuit for short intervals of time, the ratio of time between the exclusion of the resistor 5 from the field winding circuit and the inclusion of the resistor I in the circuit determining the effective value of the resistor U in controlling the current in the winding 4.
  • This charging current increases the energization of the relay winding I to a value sufficient to cause separation of the contact members I and Ill prior to the time that this would occur if controlled by the voltage between supply conductors 2 and I alone, thus introducing a stabilizing or anti-hunting action into the regulator to limit the amount of over-travel in the voltage between conductors 2 and 2.
  • the separation or the contact members II and it causes the separation of the secondary relay contact members 2i and 22, to reintroduce the resistor i in circuit with the field winding l and,, at the same time, to reestablish the potential ,diflerence between Junction points 2! and 30 which are the terminals of the condenser 2!, to their former value, thus causing the charge that has been established on the condenser 22 to dissipate itself by a current flowing in the opposite direction, or from condenser 28 through the relay winding 1 in a direction opposite to the flow or the regulating component of current through that winding between conductors 2 and 3.
  • the primary relay contact members II and I! and the secondar relay contact members 2i and 22 are brought into engagement and separated from engagement at earlier times in the regulating cycle upon a decrease or increase, respectively, in the voltage of the regulated generator on account of the stabilizing or anti-hunting action of a charging current flowing to the condenser 28 and a discharging current flowing from the condenser 28, as above described.
  • This stabilizingior anti-hunting action is independent of the load on the regulated generator and is the same for all conditions of the circuit within the limits for which the regulater is adjusted.
  • a dynamo-electric machine for supplying unidirectional current to circuit supply conductors and provided with a field winding, a field energizing circuit including said field winding and a field controlling resistor connected in series between said supply conductors, a primary relay 'for intermittently short cirouiting said resistor tor controlling the eilective value thereof, a control circuit including the operating winding of said primary relay and a control circuit resistor, and anti-hunting means comprising a condenser connected from aJunction point between the field winding and the regulating resistor and a junction point between the primary relay winding and the control circuit resistor.
  • a dynamo-electric machine for supplying unidirectional current to supply circuit conductors and provided with a field winding, a field energizing circuit including said field winding connected to one of said conductors and a field regulating resistor between said field winding and the other of said supply conductors, a regulating relay having a winding for intermittently short circuiting said control resistor, a control circuit for connecting said relay winding to the first named of said conductors and including a control circuit resistor between said relay winding and the other of said conductors, and a condenser connected between said field winding and said relay winding.
  • a dynamo-electric machine for supplying unidirectional current and provided with a field winding, a field energizing circuit including said field winding and a field controlling resistor connected in series between the terminals oi said thmamo-electric machine.
  • regulating means including a relay for eflecting the intermittent short circuiting of said field controlling resistor, a control circuit including the winding of said relay and a control circuit resistor connected in series between the terminals oi said dynamo-electric machine, and energy storing means connected between said' field winding and said relay winding that is responsive to a change in the voltage supplied to said field .winding Ior eilecting a stabilizing current through the relay winding.

  • a dynamo-electric machine having a field winding connected in circult between the terminals thereof, said circuit ing a stabilizing component of current to flow through said relay winding upon a change in th voltage applied to said field winding.
