Definitions

  • the invention relates to voltage regulators, especially to power regulators, intended for use in power regulation, where their output is connected to a large system, being a big electrical last, and where a voltage regulation is used for changing an immediate power of all the devices in said system and for saving energy this way.
  • output taps each having different voltage
  • Voltage regulation is provided here by switching those taps with the different voltage.
  • This type of circuitry js relative simple, but the drawback is a voltage changing in steps and a switching under a full load.
  • the transformers working as autotransformer are known, where output voltage is regulated by ' in series with a load mounted winding influenced by another, second winding, using the same magnetic core.
  • control current is supplied to the second winding, the magnetic saturation of the magnetic core is growing and therefore the impedance of the first winding is decreasing and so an output voltage is regulated.
  • This type of regulator is described in CZ PV 2002-398 published patent application specification.
  • Control current is supplied here by autotransformer, where plurality of output taps are created on its winding and the device is " so created that switching those taps is possible.
  • a relay set is provided, so a current changing in control winding is achieved and consequently a changing of voltage on the load is achieved, too:

  • control voltage source is connected to an input from a distribution electricity network and in this source at least one control member is contained and at least one control input of the control voltage source is connected to a secondary winding. It could be advantageous, if at least one control input of the control voltage source is connected to remote control signal receiver. Another control input of the control voltage source can be connected to a timing apparatus. oncerning a winding in the toroid-core transformer, it is advantageous if a ratio of primary and secondary winding is from 1 : 1,1 to 1 : 1,3. Just more advantageous is, if this ratio is from 1 : 1,23 to 1 : 1,27. It could be also an advantage, if a secondary winding output is connected to a power factor compensation unit.
  • This regulation is useful in situation, when lower network voltage is not sufficient for normal work of some device supplied by this network, or when low voltage causes insufficient output of some device supplied. Especially when using a transforming ratio about 1 : 1 ,25, wide and optimal range of regulation is achieved. It is possible both to apply the decreasing of voltage for full energy consumption saving, or to apply the increasing of voltage for full compensation of network voltage decreasing.

  • Information about an actual voltage on secondary winding 102 is coming from this secondary winding 102 to the control voltage source 2 over a first control input 22. So a regulation of secondary voltage is achieved, where this voltage could be until by 30% decreased or until by 10% increased.
