  • the invention relates to a motor drive for tap changer, diverter and Tauchkernspulen according to the preamble of the first claim.
  • the generic motor drive is preferably used to adjust the tap changer to the respective desired operating position.
  • the load gearbox directly actuates the tap changer; It has a correspondingly dimensioned electric motor.
  • the timing gear is located on the side of the load gear and contains a cam which rotates one full turn each time the tap changer is changed. This cam includes a plurality of switching cams for the mechanical actuation of numerous cam switches or cam-actuated contacts, which are also part of the still to be explained electrical components.
  • the control gear further includes means for displaying the tap position or the switching step. .
  • the most important electrical components in the motor drive are the different circuits.
  • the control of the motor drive is based on the principle of stepping, i. an adjustment by a switching step is initiated by a - one-time control pulse and then inevitably completed.
  • the output shaft of the motor drive which is coupled in the assembled state with the drive shaft of the tap changer, doing 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.
  • Trigger motor protection switch and thus shut down the motor drive to prevent it from passing.
  • timing relays themselves are relatively susceptible to interference and, because of the electronic components that are required, also quite expensive. Furthermore, additional contactor contacts are required for their excitement.
  • the object of the invention is therefore to provide a novel motor drive with a continuous protection, which is simple and inexpensive and yet, even self-monitoring, works without errors.
  • two additional control cams are provided in the control gear, which correspond to additional cam-controlled monitoring contacts and monitor the contactor contact points and trigger the motor protection switch in improper contact position, which could lead to an / unauthorized engine passage on the new position to be driven into the final position.
  • a time relay according to the prior art for this purpose is generally superfluous.
  • 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 step-by-step relay and 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.
  • An undesired passage of the motor drive can have two different causes:
  • the motor contactor can "stick", then the motor drive runs through to the end position.
  • the relay for the stepping does not attract - whether it is itself 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 cooperate with a respective cam-controlled monitoring contact actuated by them, enable reliable protection against passage through both faults with minimal damage
  • the motor drive according to the invention no longer requires a time relay; Rather, only mechanical parts are present, which have a low StöröranfäUmaschine.
  • Fig. 1 shows the circuit of a motor drive according to the invention
  • Fig. 2 shows the actuating sequence of the contacts involved in the circuit shown in Fig. 1, which are controlled by the cam, at a switching, i. a rotation of the cam 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 present in the prior art.
  • a stepping relay K 20 Also known is the illustrated arrangement of a stepping relay K 20. Furthermore, according to the invention the additionally provided cam-controlled monitoring contacts S15 and S16 are arranged in this part of the circuit. Further elements of the circuit are a pushbutton S3 for manual actuation of the motor contactor Kl, K2, a continuous contact S37, a closing contact S40 and the limit switches S4, S5, S6, furthermore a blocking switch S8.
  • the second cam-controlled monitoring contact S16 closes. Since the contact K20: 33-34 is normally not yet closed and the contact K2: 31-32 is already open, the motor protection switch will not trip if the function is correct. In this switching step is thus checked by closing the monitoring contact S16, if the motor contactor Kl, K2 and / or the stepping relay K20 are defective.
  • K20 is activated and picks up.
  • K20: 23-24 and K2: 13-14 K20 is in self-holding.
  • the first cam-controlled monitoring contact S15 closes and thus checks whether K20 has properly tightened. Normally K2: 43-44 is closed and K20: 51-52 is open. The motor protection switch will not trip when properly operated.
  • K20 does not fall off immediately because K2: 13-14 is still closed.
  • Monitoring contacts S15, S16 monitor the motor contactor K1, K2 and the stepping relay K20. This is done, as explained, in that the second monitoring contact S16 is closed by the cam zeithch after the pulse and shortly thereafter reöflhet again and the first monitoring contact S15 at a later time zeithch after the activation of the stepping contactor K20 also closed and shortly thereafter reöflhet becomes.
  • This operation is realized by appropriately arranged switching cam on the cam.
  • the complete switching process is subdivided into 33 individual consecutive time steps, which are displayed in a known manner by a switching step indicator wheel.
  • the short-term closing of the second monitoring switch S16 after the impulse is as well as the momentary Schhe touch the first monitoring switch S15 at a later time after the activation of the stepping contactor K 20 by purging of S13 verdeuthcht.

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.
