Definitions

  • the arrangement consists substantially of a clock and a power indicator.
  • Figure 1 shows an arrangement for controllin the power output of an electric generator driven by -a water turbine W by means of a pin S sliding in the slot P of a timetable T and coacting with the pointer Z of the wattmeter 70.
  • Figure 2 shows the timetable fastened to and raised from the surface of the drum 3 rotatable by clockwork.
  • the clock drives a drum provided with an hour scale, which makes one revolution in 24 hours.
  • the power time table cut out of cardboard or sheet metal is fixed 'in such a manner that I above each hour division there appears the power output in megawatts of the machine to be controlled prescribed for this moment.
  • T is the developed surface of g the timetable and? the slot fixed in it.
  • the motion of the pin S is transmitted by means of a rod X to a lever H which is pivoted so as to turn about the axis of rotation of the pointer Z of the wattmeter k of the machine to be controlled, in such a'manner that the centre line bb of the pivoted ,lever H adjusts itself to a power indication on the wattmeter scale corresponding to the power on the time table where the pin S at the moment rests.
  • the pointer will close over the contact a the armature circuit of the servo motor in the op posite sense and will cause the machine to develop less power.
  • a water turbine W is rovided for driving the electric enerator the guide blades of the said tur ine being displaced by the regulator R.
  • the pivot d of the regulator The the surface of the drum 3 so that when tr'av- 1 2 accents lever c is dispiaced Tog means of being tastened to the nut m, w ich is d iacea ie on the screw spindle a driven by t e motor M.
  • this arran ement is only one of the 5 numerous constructional forms possible ac cording to the invention.
  • the above description relates to the control efiected by a power time table.
  • the er rangement may of course he used in the same manner for operating with another time table for instance-atoitage, periodicity, idle cur rent, swam pressure and the like time table
  • the fire of a boiler may he antematicaiiy controlled by increasing the draught and ecceierating the coal supply; with or without a corresponding lead with re spect to the power time table.
