Definitions
- the invention relates to a tap changer for uninterrupted switching between winding taps of a tapped transformer.
- a motor drive is provided laterally outside the transformer tank of the tapped transformer or in the immediate vicinity, which has a drive motor and other components and a drive rod with the head of the in the
- Transformer boiler built-in tap changer is connected and thus the stepper switch motor operated with each change.
- a typical engine drive is
- WO 01/92978 A1 for example, from WO 01/92978 A1 known. It includes a drive motor, a load gear, a control gear, monitoring and display elements, eg. Legs
- the drive train d. H. Drive shafts, angle drive u. a., Individually adapted to the respective spatial conditions on the transformer and the tap changer head.
- the actuating motor drive itself must also be matched to the respective tap changer with which it is intended to interact.
- the number of adjustable voltage levels, the number of revolutions of the drive shaft per switching and the type of position indicator must be individually adapted to the corresponding tap changer.
- this known arrangement is therefore complicated in structure and requires a customer-side adaptation of the individual modules to each other and accurate positioning each other.
- the object of the invention is to provide a compact, low-cost tap changer, which does not have these disadvantages.
- the invention is based on the general idea necessary for the drive
- Step switch to arrange.
- the motor drive according to the invention comprises both the actual electric drive motor and control gear, monitoring and display elements.
- the monitoring elements comprise in a particularly simple manner both the end position limitation and the position signaling device.
- the electric motor of the motor drive acts directly on the drive shaft of the tap changer, with which he is constantly mechanically connected, to a known energy storage.
- the electric drive motor is designed as a geared motor, so that no additional transmission gear, as usual in the prior art, the step switch is more necessary.
- the angle of rotation of such a geared motor corresponds to the angle of rotation of the drive shaft of the tap changer at a load switching.
- the angle of rotation of such a geared motor corresponds to the angle of rotation of the drive shaft of the tap changer at a load switching.
- Rotation angle of such a geared motor 40 degrees / circuit amount corresponds to a corresponding part of the Olgefäßes, in which can reach 9 positions.
- Figure 1 shows the head of a tap changer according to the invention
- a tap changer head 1 is shown, which is attached to the upper end of an only indicated Olgefäßes 2 of the tap changer.
- Olgefäßes 2 of the tap changer.
- the wall of the oil vessel 2 are - here only indicated - in one or more horizontal planes a, b, c fixed stage contacts n, n + 1, ... at a radial distance from each other, which corresponds to the respective pitch.
- a centric In the oil vessel 2 is located in a known manner a centric
- the tap changer head 1 is the actual compact motor drive, according to the invention as an integral part of the tap changer, comprising a geared motor 3.
- This geared motor 3 is designed as a compact assembly and consists of the actual electric motor 3.1 and a gear assembly 3.2.
- Transmission assembly 3.2 also has a by driving the electric motor 3.1 with a corresponding translation through the gear assembly 3.2 drivable hollow shaft 3.3, which is mechanically connected directly to the drive shaft 4 of the tap changer.
- the motor drive has a control gear 5, which will be discussed in more detail below, a cover 6 and electric
- Fig. 2 shows that the control gear 5 has a further drive shaft 8, which in turn is driven by the drive shaft 4 and thus the hollow shaft 3.3.
- the drive shaft 8 With the drive shaft 8 in communication are gear wheels 9, 10, 11, 12th
- the control gear 5 further comprises known cams 13, which are each provided with an end-face contour, which in turn correspond to cam switches 14.
- Above the transmission gears 9 ... 12 is a
- Position indicator wheel 15 the front side has an upper part contour 15.1 and a lower part contour 15.2.
- this partial contours 15.1 and 15.2 are either directly or, as shown here, by blocks 15.3, 15.4 position signaling contacts 16 actuated.
- Switch monitoring device with a cam to provide horizontally split contour, but the device described therein refers to a powerless switching diverter, which has no motor drive at all, also it is above an upper gear stage arranged in a separate housing, so it can not with the position indicator wheel 15 of Invention are compared.
- Sliding contact 17 is provided.
- Position indicator on the other hand united by the specially trained position indicator wheel 15 - a compact and inexpensive solution.
- terminals 18 are still shown, of which not shown electrical
- Tap-changer head 1 directly provides an integral part of the tap-changer.
- the invention dispenses with additional additional gear in the tap changer to the necessary translation of the rotational movement according to the prior art, rather, there is a direct actuation of the drive shaft 4 and thus the force accumulator of the tap changer by the hollow shaft 3.3.
- the coaxial drive shaft 8 of the control gear 5 is actuated.
- the motor drive with its components is an integral part of
- the invention particularly advantageously combines the electrical limit stop, which according to IEC separately for the control and the motor circuit takes place, with the functionality of the position message.
