Definitions

  • the invention relates to a motor drive for tap changers, diverters and plunger core coils according to the preamble of the first claim.
  • the generic motor drive is preferably used to set the tap changer to the desired operating position.
  • the load gearbox operates the tap changer directly; for this purpose, it has an appropriately dimensioned electric motor.
  • the control gear is arranged on the side of the load gear and contains a cam disk which rotates one full revolution each time the step switch is switched. This cam disk contains a large number of switching cams for the mechanical actuation of numerous cam switches or cam-actuated contacts, which are at the same time part of the electrical modules to be explained.
  • the control gear also contains means for displaying the step position or the switching step. /
  • the most important electrical components in the motor drive are the different circuits.
  • the motor drive is controlled according to the principle of step switching, i.e. an adjustment process by one switching step is initiated by a one-time control pulse and is then necessarily brought to an end.
  • the output shaft of the motor drive which is coupled to the input shaft of the tap changer when fully assembled, performs a precisely defined number of revolutions.
  • the running time of the stepping circuit is determined by a control cam of the control gear with one revolution per stage.
  • a DurcUau protection device which prevents the motor drive from running through to the end position if the step control described fails. Such a failure of the step control can occur if, for example, a motor contactor "sticks" or a coil of the step switching relay, which is part of the step control, becomes defective.
  • this continuous protection is implemented by an additional time relay in the control circuit, which is excited by contacts of the motor contactor. If the corresponding motor contactor is used after a specified time, in practical operation e.g. 7 seconds, has not yet dropped, i.e. If a new unwanted changeover from one stage to an adjacent other stage of the tap changer begins, the timing relay triggers the motor protection switch and thus stops the drive.
  • timing relays used are themselves relatively susceptible to faults and also quite expensive because of the required electronic components. Additional contactor contacts are also required to excite them.
  • the object of the invention is therefore to provide a new type of motor drive with a continuous protection, which is simple and inexpensive and yet works self-monitoring and error-free.
  • two additional control cams are present in the control gearbox, which correspond to additional cam-controlled monitoring contacts and monitor the contactor contact points and trigger the motor-protective circuit-breaker if the contact position is incorrect, which could lead to an impermissible motor run beyond the new position to be controlled and into the end position.
  • a time relay according to the prior art is generally superfluous for this purpose.
  • the first control cam according to the invention with the corresponding first additional cam-controlled monitoring contact monitors the position of the contactor contact of the relay for the stepping circuit
  • the second control cam according to the invention in turn monitors the position of the motor contactor with the corresponding second additional cam-controlled monitoring contact.
  • the motor contactor can "stick", then the motor drive runs through to the end position.
  • the relay for the step switching does not pick up - be it that it is defective or that there is a fault in the supply line - then the motor drive also runs through to the end position.
  • the two control cams provided according to the invention which each interact with a cam-controlled monitoring contact actuated by them, enable reliable protection against runs caused by both errors with minimal
  • Step switching is present and a maximum of one step adjustment if there is an error on the
  • Motor contactor is present - at the latest then the motor protection switch is triggered.
  • Fig. 1 shows the circuit of a motor drive according to the invention
  • Fig. 2 shows the actuation sequence of the contacts involved in the circuit shown in Fig. 1, which are controlled by the cam, during a changeover, i.e. a rotation of the cam disc of 360 degrees.
  • FIG. 1 the complete circuit of a motor drive according to the invention is shown.
  • the left part shows the motor circuit with the motor Ml, a motor protection switch Ql, the motor contactor Kl, K2 and a heating resistor Rl.
  • the right part shows the control circuits with the cam-controlled contacts S12, S13, S14, which are also available according to the prior art.
  • a stepping switch relay K 20 The arrangement of a stepping switch relay K 20 is also already known. Furthermore, the cam-controlled monitoring contacts S15 and S16 additionally provided according to the invention are arranged in this part of the circuit. Further elements of the circuit are a push button switch S3 for manual actuation of the motor contactor Kl, K2, a flow contact S37, a closing contact S40 and the limit switches S4, S5, S6, and a blocking switch S8.
  • the second cam-controlled monitoring contact S16 closes.
  • the motor protection switch does not trip if it functions properly. In this switching step, it is checked by closing the monitoring contact S16 whether the motor contactor Kl, K2 and / or the stepping relay K20 are defective.
  • K20 61-62 opens and interrupts the self-holding for K2.
  • K2 is now only held via S12: N01-N02.
  • the first cam-controlled monitoring contact S15 closes and thus checks whether K20 has tightened properly. Normally K2: 43-44 is closed and K20: 51-52 is open. The motor protection switch is not triggered if it functions properly.
  • Monitoring contacts S15, S16 monitor the motor contactor Kl, K2 and the stepping relay K20. This takes place, as explained, in that the second monitoring contact S16 is closed by the cam disk at a time after the impulse is given and is opened again shortly thereafter, and the first monitoring contact S15 is also closed at a later point in time after activation of the step contactor K20 and opened again shortly thereafter becomes.
  • This actuation is realized by correspondingly arranged switching cams on the cam disk.
  • FIG. 1 This representation shows the entire changeover process of the tap changer, in which a complete rotation of the cam disk and a switching step indicator wheel connected to this cam disk occurs in the motor drive.
  • the complete switching process is divided into 33 individual, sequential time steps, which are displayed in a known manner by a switching step indicator wheel.
  • the short-time firing of the second monitoring switch S16 after the impulse is given, as well as the short-term firing of the first monitoring switch S15 at a later point in time after actuation of the step-by-step contactor K 20 by firing S13.

Abstract

L'invention concerne un entraînement à moteur pour un disjoncteur progressif, un ajusteur de tension ou une bobine à noyau plongeur, entraînement comportant une fonction de surveillance du temps d'exécution au moyen de contacts mécaniques supplémentaires. Deux contacts de surveillance supplémentaires vérifient, à différents instants de la séquence s'exécutant lors d'une commutation, si le contacteur du moteur d'une part et le relais progressif d'autre part se trouvent dans des états fonctionnels corrects, car il peut y avoir un cycle involontaire de l'entraînement par moteur provoquant un déplacement jusqu'à la position finale en cas de dysfonctionnements de ces éléments. L'entraînement à moteur est arrêté lorsque la surveillance constate qu'au moins un de ces éléments ne se trouve pas dans un état normal.
