Definitions

  • the present invention relates to a system as defined in the preamble of claim 1 for saving energy in an elevator.
  • a system is known for example in document GB-A-2 139 831.
  • FIG. 1 presents a simplified circuit as provided by the invention.
  • a three-phase mains voltage is applied to a frequency converter 15 consisting of a rectifier 3, an inverter bridge 2 and an intermediate circuit 4,10,11 connected between these.
  • a frequency converter 15 consisting of a rectifier 3, an inverter bridge 2 and an intermediate circuit 4,10,11 connected between these.
  • the inverter bridge 2 converts the alternating voltage supplied by the drive motor 1 into a direct voltage, which is applied to the conductors 10 and 11 of the intermediate circuit 4,10,11.
  • a direct voltage converter 5 a battery 6 is charged with this voltage. In the solution of the invention, only one battery 6 is needed.
  • the power generated by the braking operation in frequency converter driven elevators (the voltage is about 650V and the current 1...3 A) is converted by means of a chopper type direct voltage converter 5 to a level of approx. 30V / 20...50A, which is well suited as a power source for an elevator and for the charging of 24V batteries.
  • 'Chopper type converter' means a transformer implemented using semiconductors and small-size ferrite core transformers which has an efficiency comparable to that of a transformer but which provides a better degree of regulation.
  • the same direct voltage converter 5 is used to supply power to the whole control system.
  • the direct voltage converter 5 can be used to produce a raised voltage for the elevator's safety circuit, which consists of door contactors and other safety switches and prevents the elevator from starting when the doors are open or it is otherwise hazardous to set the elevator in motion.
  • the elevator acts as an energy source, charging the battery 6 with a large current of 20...50A, and during approx. 80% of the time the energy stored in the battery 6 is used to supply power to the control equipment of the elevator, the control system, the brake and the signalling etc. Energy is supplied e.g. to the elevator control unit, identified by number 7 in the figure. This control unit needs a significant amount of electric energy.
  • the brake 8 of the elevator refers in the first place to the braking electromagnet, which also consumes quite a deal of energy
  • elevator lighting 9 refers in the first place to the car light, which generally requires a battery as a reserve power source.
  • the capacitor 4 reduces high-frequency noise passed to the mains network.
  • the energy generated during braking is converted to a lower voltage and supplied to elevator equipment as specified above and to the battery 6.
  • operation is almost the same as above but the power is taken from the electric network.
  • the transmission of braking energy into the battery 6 is controlled by adjusting the voltage to a suitable level. Voltage control also ensures that the battery 6 has a sufficient voltage.
  • Another feature of the invention is that it integrates the power sources of the elevator's drive and control systems into a single whole. So far, these have been separate from each other, which has caused additional expenses and problems relating to quality and disturbances.
  • reserve power operation of the elevator can be implemented so as to allow the elevator to be driven at a reduced speed for a few hours.
