Definitions

  • the invention relates to a drive system for a switch and a method for driving a switch.
  • switches For the regulation of voltage in different transformers, there is a large number of switches for different tasks and with different requirements. To operate the respective switches, they must be driven by a drive system. These switches are, among other things, on-load tap-changers, diverter switches, selectors, double-turners, reversers or preselectors.
  • a drive for one of the switches mentioned above is known, for example, from DE 20 2010 01 1 521 U1.
  • a motor is arranged in this on-load tap-changer drive and is rigidly connected to the corresponding on-load tap-changers via linkage. It is operated by means of wiring, i.e. the motor is switched on or off by actuating motor contactors.
  • the on-load tap-changers are then operated via the drive shaft. Functional changes to the drive are not possible after installation and commissioning. This makes the drive rigid and inflexible. The simplest adjustments require complex conversion measures.
  • a further object of the invention is to provide a method for driving at least one switch which provides an improved concept for driving a switch by means of which the flexibility of the drive and the safety of the switching are increased.
  • 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 so that, depending on the feedback signal, a stored driving profile is selected from a plurality of driving profiles. The selected driving profile acts accordingly on the motor.
  • the control device comprises a control unit and a power part, the power part serving to supply energy to the at least one motor.
  • the stored travel profiles are stored in a memory of the power unit.
  • the driving profiles are stored in a memory of the control device or the control unit.
  • the feedback system comprises at least one absolute value encoder which is set up and arranged to detect an absolute position of the drive shaft or an absolute position of a further shaft which is connected to the drive shaft. On the basis of the detected position, at least one output signal can be generated which is set up to determine the position of the drive shaft on the basis of the at least one output signal.
  • the absolute encoder can be designed as a multiturn or singleturn encoder.
  • the absolute encoder can be set up to detect the position of the drive shaft or the position of the further shaft using a first scanning method.
  • the scanning method can be an optical, a magnetic, a capacitive or an inductive scanning method.
  • the feedback system can contain at least one absolute value transmitter and an auxiliary contact which, in combination with the absolute value transmitter, is set up and arranged to detect an absolute position of the drive shaft or an absolute position of a further 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 on the basis of the at least one output signal.
  • the absolute encoder can be designed as a single-turn rotary encoder or incremental encoder or 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 a polynomial function of the nth order in a two-dimensional Cartesian coordinate system.
  • the drive system can be designed in such a way that the control device acts on two motors.
  • the control device comprises at least one, optionally two power sections, each motor cooperating with a common power section or each motor with its own power section.
  • control device is designed in such a way that it interacts with one of the two motors.
  • This motor follows the travel profile of the actual value of the feedback system of the other motor.

  • the drive system stops when the reachable switch position is reached.
  • the advantage of the method according to the invention is that by using the driving profile, a high degree of flexibility and variability can be achieved when switching over in a switch. Mechanical changes in the switch that can influence the switchover are absorbed by using the travel profiles; it is thus possible to adapt the driving profiles accordingly.
  • At least one travel profile is determined for the drive shaft for driving the switch. As a rule, a large number of travel profiles are determined for a switch. The minimum At least one specific driving profile is saved for use in a circuit.
