Definitions
- the present invention relates to a load selector. More particularly, the present invention relates to a load selector comprising a switching tube rotatable about an axis, at least one switching segment fixed to the switching tube, and at least two vacuum interrupters.
- the vacuum interrupters are arranged in the at least one switching segment.
- Each vacuum interrupter has in the direction of the axis of the switching tube a movable contact which cooperates at its free end with an actuating lever.
- Such load selectors belong to on-load tap-changers (OLTC) and are well known and commonly used in the prior art They are used for uninterrupted switching between different winding taps of tapped transformers
- OLTC on-load tap-changers
- vacuum interrupters vacuum switching cells
- vacuum switching elements are used as switching elements for load switching. This is based on the fact that the use of vacuum interrupters for load switching prevents arcing in the oil and thus the oil contamination of the diverter switch, as for example in German Patent DE 195 10 809 C1 and DE 40 1 1 019 C1 and German Patent Application DE 42 31 353 A1 and DE 10 2007 004 530 A1.
- European Patent Specification EP 1 078 380 B1 describes a load selector for tapped transformers wherein a plurality of vacuum interrupters are arranged annularly and in the same direction on contact carriers, since the contact arrangement consists of a plurality of step contacts fixedly arranged in a circle on a cylinder.
- the contact carriers have sliding contacts, which are guided by rollers in a diverter ring.
- the vacuum interrupters are controlled by control cams in this diverter (actuator).
- the vacuum interrupters are each controlled by a lower cam track and an upper cam track. Both cam tracks (control cams) are each arranged on a concentric circle in the amount of the actuating contacts (actuating tappet) of the vacuum interrupters.
- the two concentric circles are directly and directly adjacent to each other, so that they together form an upper disc in which are located exclusively the actuating plunger of the vacuum interrupters. Opposite lying are the lower ends of the vacuum interrupters without actuating plunger on the contact carrier and form a lower disc without actuating contacts.
- the two circular discs are spaced and in between the middle parts, such as the bellows, the vacuum interrupters are arranged.
- the vacuum interrupters are also arranged in the same direction in a ring with a control ring, the one or two includes directly and immediately adjacent annular cam tracks.
- the vacuum interrupters taper in the direction of the actuators, whereas they widen towards the opposite ends.
- the outer shape of vacuum interrupters is usually at least approximately conical.
- a disadvantage of this external shaping with load selectors with vacuum interrupters arranged in the same direction is that the oil vessel (insulating cylinder, contact cylinder) of the load selector, in which oil vessel the vacuum interrupters are arranged in the same direction, must have a large diameter, so that the load selectors are correspondingly less compact and space-saving.
- the object of the invention is therefore to provide a compact and space-saving load selector, which can always perform the same predetermined switching operations and also exploits a limited space for installation and service friendly. This object is achieved by a load selector comprising the features of claim 1.
- the on-load tap-changer comprises a diverter switch insert with a switching tube rotatable about an axis, at least one switching segment fastened to the switching tube and at least two vacuum interrupters.
- the at least two vacuum interrupters are arranged in the at least one switching segment.
- Each vacuum interrupter has in the direction of the axis of the switching tube a movable contact which cooperates at its free end with an actuating lever.
- the vacuum interrupters are arranged alternately in opposite directions such that the movable contacts of the vacuum interrupters are movable in an alternately opposite direction with respect to the axis of the switching tube.
- this means for vertically arranged on-load tap-changer that the movable contacts of the vacuum interrupters aligned alternately up and down in the respective switching segment and the fixed contacts of the vacuum interrupters are also alternately reversed up and down aligned saves space, since the approximately conical vacuum interrupters are arranged alternately side by side such that the "conical tips" are arranged with the free ends of the movable contacts adjacent to the "conical bottoms" with the fixed ends of the vacuum interrupters.
- the space of the load selector can be better utilized by this arrangement. Less material must be used in the production of such a compact load selector, which reduces both the manufacturing costs of the load selector and the location costs of the load selector.
- each switching segment comprises a contact carrier in which movable contacts for a diverter / guide ring, movable contacts for at least one stage contact and the at least two vacuum interrupters are held.
- the contact carrier has further formed a bearing block for each operating lever.

- the contact carrier may have a pivot axis transverse to the axis of the switching tube include.
- the contact carrier in this case preferably has an upper housing part and a lower housing part, between which the vacuum interrupters are alternately inserted in opposite directions in the contact carrier. This means that, with respect to adjacent vacuum interrupters, a movable contact with the free end of the respective vacuum interrupter alternately engages through the upper housing part or through the lower housing part. Conversely, a fixed end of the respective vacuum interrupter is alternately fixed in the lower housing part or in the upper housing part.
- each switching segment has two vacuum interrupters.
- each switching segment is associated with an actuating element for actuating the actuating lever.

- the load selector comprises three phases. Each phase is assigned at least one switching segment and at least one actuating element.
