摘要： The invention relates to a method for averaging the voltage in an on-load tap changer used to switch between various winding taps of a tapped transformer. The general inventive concept consists in reaching a predefined operating position of the on-load tap changer by having a parameterized control device activate a motor drive in a first rotational direction once the on-load tap changer has been turned on, such that the on-load tap changer starts running through its stationary operating positions, i.e. the various winding taps of the tapped transformer, in the direction of the first tap; the control device recognizes when the on-load tap changer has reached its final position, whereupon the motor drive is activated in a second rotational direction such that the on-load tap changer then runs through the control range in the opposite switching direction until reaching the first stationary operating position; the first stationary operating position is subsequently configured as a predefined operating position using the control device parameterization stored in a non-volatile manner.

摘要： The invention relates to a position signaling device for step switch, tap changer or plunger coil motor drives. The inventive device consists of two separate sub-assemblies. i.e. a contact signaling device and a physically separate, differently configurable position signalling module, wherein both sub-assemblies are electrically interconnected in such a was as to enable the information obtained in the contact signalling device to be transmitted to the position signaling module where the information is appropriately processed according to the type and manner of display desired. Said processing can be easily obtained by selecting the appropriate corresponding electrically and internally connected position signaling modules.

摘要： Die Erfindung betrifft einen Stufenschalter nach dem Reaktorschaltprinzip zur unterbrechungslosen Lastumschaltung mittels Vakuumschaltzellen. Erfindungsgemäß weist dieser Stufenschalter drei separate Isolierwellen auf; die erste dieser Isolierwellen dient zur Betätigung der beweglichen Wählerkontakte aller Phasen, die zweite dieser Isolierwellen dient zur Betätigung der beweglichen Vorwählerkontakte, und die dritte dieser Isolierwellen dient zur Betätigung der beweglichen By-pass-Kontakte einerseits und der der jeweiligen Phase zugeordneten Vakuumschaltzelle andererseits. Zur Betätigung der Isolierwellen wiederum dient ein einziges, seitlich angeordnetes Getriebe, durch das die entsprechenden Drehbewegungen der einzelnen Isolierwellen entsprechend der zu realisierenden Schaltsequenz erzeugt werden.

摘要： The invention relates to a motor-drive position indicator for actuating a sequence shift, a change-over switch or a moving coil. To achieve this, a first circular scale is provided with symbols arranged thereon. Said symbols are allocated to each individual switching stage involved when changing from one motor-drive working position to another. The first scale is swept by a first pointer which rotates at 360° each time switching occurs. A second circular scale is also provided with symbols arranged thereon. Said symbols are allocated to each possible working position of the sequence shift or other. The second scale is also swept by a pointer. The second pointer performs a rotational movement around an angle corresponding to the distance between two adjacent symbols on the second scale each time that switching occurs. Trailing pointers are arranged on both sides of the second pointer in such a way that one of them is pulled along according to the direction of rotation when the second pointer rotates. Both trailing pointers thus indicate the actual control range which is switched.

摘要： A step switch for step transformers has a motor drive with a driving unit and an information unit. Whereas the driving unit contains in a manner known per se the driving motor and its control that actuates it depending on the direction of the rotation, the information unit contains, according to the invention, the following means: a sensor for detecting the absolute value of the instant position of the step switch; non-volatile storage means for the step position; non-volatile storage means for the position of the step switch within a step position range; means for recognizing an end position of the step switch; programmable means for storing specific step switch data; serial data processing electronic means; electronic means for controlling and monitoring the switching process and an electric connection with the regulator and other display, operation and control means that consists of a single serial data line.

摘要： The present invention relates to a motor drive having a position indicator for actuation of an on-load tap changer or diverter. The invention proposes a motor drive for actuating an on-load tap changer or diverter. This diverter has a drive motor which drives at least one load gear and an indicator gear, wherein the load gear has a first drive shaft, having a first drive pulley which is mechanically connected thereto and is connected to the drive motor, and a second drive shaft having a second drive pulley which is connected thereto. The first and second drive pulleys are mechanically coupled, wherein the second drive shaft itself is operatively connected on the first side thereof to the on-load tap changer or the diverter and can be connected by the second side thereof to the indicator gear. The indicator gear co-operates with a position indicator, by means of which the currently activated position of the on-load tap changer or diverter can be displayed, and wherein a switchable coupling device can be provided between the position indicator and the load gear.
