Definitions

  • the invention relates to a drive system for a switch and a method for driving a switch.
  • switches for regulating voltage in different transformers for different tasks and with different requirements. In order to operate the respective switches, they must be driven via a drive system. These switches include on-load tap changers, diverter switches, selectors, double turners, turners or preselectors.
  • a drive for one of the switches mentioned above is off DE 20 2010 011 521 U1 known.
  • a motor is arranged in this on-load tap changer drive, which is rigidly connected to the corresponding on-load tap changers via a linkage.
  • the actuation is done by wiring, i.e. the motor is switched on or off by actuating motor contactors.
  • the on-load tap changers are then actuated via the drive shaft.
  • functional changes to the drive are not possible. This makes the drive rigid and inflexible. The simplest adjustments require complex conversion measures.
  • the patent specification WO 00/36621 A1 describes an actuating device for operating and controlling an electrical switching device for use in a high or medium voltage transmission network.
  • the actuating device comprises a rotating electrical machine, which is connected to a movable contact via a coupling without having a mechanical spring.
  • the clutch converts the rotational movement of the rotating electrical machine into a translational movement of the movable contact.
  • a further object of the invention is a method for driving at least one To provide a switch, which provides an improved concept for driving a switch, which increases the flexibility of the drive and the safety of the switching.
  • the drive system according to the invention is suitable for at least one switch and comprises a drive shaft which connects the drive system to the at least one switch. At least one motor is provided which is coupled to the drive shaft. A feedback system is provided which is set up to determine a position of the drive shaft. A feedback signal is generated based on this position. A control device is set up to select a stored driving profile from several driving profiles depending on the feedback signal. The selected driving profile affects the engine accordingly.
  • the control device comprises a control unit and a power section, wherein the power section serves to supply energy to the at least one motor.
  • the saved driving profiles are stored in a memory of the power unit. Alternatively, the driving profiles are stored in a memory of the control device or the control unit.
  • the feedback system includes at least one absolute value encoder and an auxiliary contact, which, in combination with the absolute value encoder, is set up and arranged to detect an absolute position of the drive shaft or an absolute position of another shaft.
  • the other shaft is connected to the drive shaft.
  • At least one output signal is generated based on the detected position.
  • the position of the drive shaft is determined based on the at least one output signal.
  • the absolute encoder can be designed as a single-turn encoder, an incremental encoder or a virtual encoder.
  • the auxiliary switch can be designed as at least one microswitch or resolver.
  • the driving profile is defined by two variables and mapped as an nth-order polynomial function in a two-dimensional Cartesian coordinate system.
  • the drive system can be designed such that the control device acts on two motors.
  • the control device comprises at least one, optionally two power sections, with each motor interacting with a common power section or each motor with its own power section.
  • control device is designed such that it interacts with one of the two motors.
  • This motor follows the driving profile of the actual value of the feedback system of the other motor.
  • the method according to the invention for driving at least one switch is characterized in that a drive system has a drive shaft connected to at least one motor.
  • a driving profile is selected that describes operation of the drive system for switching from a current switching position to an achievable switching position.
  • a position of the drive shaft of the at least one motor is recorded using a feedback system.
  • a feedback signal is generated from the recorded actual value of the position of the drive shaft.
  • the advantage of the method according to the invention is that a high degree of flexibility and variability can be achieved when switching in a switch by using the driving profiles. Mechanical changes in the switch that can influence the switching are compensated for by using the driving profiles; It is therefore possible to adapt the driving profiles accordingly.
  • At least one driving profile is determined for the drive shaft to drive the switch. As a rule, a large number of driving profiles are determined for a switch. The at least one specific driving profile is saved for use in a circuit.
  • An absolute position of the drive shaft or an absolute position of another shaft is determined with at least one absolute value encoder of the feedback system. Based on the detected position, at least one output signal is generated, with which the position of the drive shaft is determined.
  • a control device comprises a control unit and/or a power unit with which the at least one motor is controlled or regulated in such a way that the switching position to be achieved by the driving profile is reached within a time predetermined by the driving profile.
  • Each of the driving profiles is defined by two variables and represents a two-dimensional polynomial function of the nth order.
  • the polynomial function is mapped in a two-dimensional Cartesian coordinate system.
  • the driving profile specifies a speed or a torque of the at least one motor.
  • the driving profile also specifies at what time or at what position of the drive shaft, which torque or speed is implemented by the motor on the drive shaft.
  • the improved concept is based on the idea of equipping a drive system for driving a switch with a feedback system and a control device, thereby enabling the switch to be actuated via a specific driving profile.
  • an on-load tap changer is actuated in such a way that a motor at constant speed actuates a drive shaft, which moves selector contacts in parallel and draws up a spring energy storage device, which acts on the diverter switch after it has been triggered.
  • the drive system based on the improved concept is able to drive the drive shaft in a targeted manner, i.e. according to a previously selected driving profile.
  • the driving profile doesn't just specify a speed or a torque.
  • the driving profile also specifies at what time or at what position of the drive shaft, which torque or speed is implemented on the drive shaft.
  • specific sections of a circuit of the switch can be influenced. This makes it possible to increase the speed or torque based on the drive shaft position. Since different parts to be actuated are arranged in the switch on the drive shaft, these can be explicitly protected. For example, at the beginning of a switchover, a higher torque is required to release contacts or set them in motion. Immediately afterwards the torque can be reduced. This is explicitly possible with the driving profile.
