明によつて得られる利点は特に次の通りである。In on-load tap changers of this type, the polarity switch usually has a plurality of star-shaped switching contacts that can be pivoted about the switching axis, each of which has one common connection with the respective rod. It can be operated by the drive of the tap selector via an intermediate transmission. The object of the invention is to improve the known on-load tap changer and, inter alia, to simplify the arrangement of the contacts of the polarization switch and the drive connected to these contacts. This purpose is achieved in the present invention by providing that the polarity switch has one contact lever, which is connected and electrically connected to the lower cage ring, and which is connected to the lower cage ring, and which is connected to the lower cage ring. A cam provided at the lower end of the operating rod of the device allows a reciprocating swivel during the course of the switching step causing the switching of the preselector, and furthermore, The polarity switch is constituted by an insulating cylinder disposed below the tap selector, one fixed polarity switch contact is disposed inside this insulated cylinder, and this polarity switch contact This is achieved by the joint action of the contact lever and the contact lever. The advantages obtained by the invention are particularly as follows.

施例を図面をもつて示し、より詳細に説明する。That is, since the operation of one or more polarity switch contacts is performed by the aforementioned operation rod of the tap selector,
The drive described above is greatly simplified. The aforementioned individual couplings and intermediate gears for actuating the polarization switch contacts are no longer required. Functional reliability is likewise improved, since the actuation of the polarity switch contact is directly linked to the actuating rod of the tap selector, so that the opening and closing of this polarity switch contact can be done simply by tapping. This only depends on the position of the selector or the switching step. A further advantage is that the polarity switch has its own insulating cylinder located below the tap selector. This insulating cylinder, to which the tap selector C is fixed, not only forms a good mounting surface for the on-load tap changer (e.g. during installation and transport), but also serves as a housing for the polarity switch contact. As a result, this polarizing switch contact is protected from external mechanical influences. Furthermore, the plurality of polarization switch resistors in this insulating cylinder are arranged in a particularly advantageous manner,
For this purpose, the wall of this insulating cylinder can be equipped with a special plug, into which the rod-shaped, porcelain polarization switch resistor mentioned above can be inserted in a secant manner. An embodiment of the present invention will be described in more detail with reference to the drawings.

The tap selector 3 is designed as a cylindrical cage, with an upper cage ring 7 and a lower cage ring 8.
An insulating rod 9 is disposed between and supports a fixed tap selector contact 10. This tap selector 3
and the load changer 2 is an intermittent transmission 11 for the step-by-step operation of an operating rod 13 which can be pivoted around a tap selector column 12. (See Figures 2 and 3). This operating rod 13 serves for operating a movable tap selector contact, which is not shown in detail in the drawings. A preselector 4 is located to the side of the tap selector 3, and this brake selector is similarly operated by the intermittent transmission 11. Below the tap selector 3 is the polarity switch 5, and the insulating cylinder 14 of this polarity switch is screwed onto the lower basket ring 8t. This insulating cylinder 14 has an external connection terminal 15 to which a conductor 16 is connected which is connected to the corresponding tap selector contact 10. Further details of the polarization switch 5 and its operating device are shown in FIGS. 2 to 5.

3, a rotatable ring 18 is arranged,
This ring guides the operating rod 13, which is driven by the intermittent transmission device 11 (FIG. 1). The individual struts 17 of the lower cage ring 8 have legs 19 to which the insulating cylinders 14 of the polarization switch 5 are screwed. A contact lever 21 is supported by a bearing portion 20 in one of the pillars 17 of the lower cage ring 8. The contact lever is radially pivotable, and
It is permanently electrically connected to the lower basket ring 8 through two contact portions 22 and 23. spring 24
applies the necessary contact pressure to the contact part, and at the same time also applies force to the contact lever 21, so that this contact L-bar, at its lower contact 25, presses into the insulating cylinder 14. is pushed away from the stationary opposing contact 26 located at. The contact between the opposing contact 26 and the contact 25 is caused by a cam 27 attached to the operating rod 13.
caused by. During the switching step of the actuating rod 13, the aforementioned cam 27 correspondingly engages the rear part of the roller 28 located at the upper end of the contact lever 21, causing this contact lever 21 to move as shown in FIG. Move in the direction of the arrow. This further stretches the spring 24 and creates an abutment between the contact 25 and the opposing contact 26. During the course of a switching step on the tap selector 3, the cam 27 correspondingly moves out of the area of the roller 28 again, so that the spring 24 moves the contact lever 21 in the opposite direction. Rotate it in the direction
The corrosive connection between contact 25 and its counter contact 26 is thus eliminated. As can be seen particularly clearly from FIGS. 4 and 5, a plurality of plugs 29 are arranged linearly on the inner wall of the insulating cylinder 14, and each of these two plugs has one plug. Rod-shaped porcelain polarizing resistors 31 are inserted, so that the individual polarizing resistors form a dividing line in the cross section of the insulating cylinder 14.

である。At the same time, this rod-shaped polarization switch resistor 31 also assumes an inclined position pointing upwards or downwards, so that the individual polarization switch resistor' is thus formed in the cross section of the arm cylinder 14. The dividing lines intersect each other.
At this time, in the embodiment shown in FIGS. 4 and 5 (a series circuit of rod-shaped polarity switch resistors 31 is arranged in permutations A, b,
c,..., are lined up corresponding to k. In this case, the first plug corresponds to a and is electrically connected to the stationary counter contact 26 mentioned above, and the last plug, corresponding to kl, forms the connection terminal 15 for the conductor 16. Furthermore, said counter-contact 26 is also provided with an external connection terminal 30, by means of which a polarization switch resistor provided at any other position could be connected. According to the present invention, the advantage of the above-mentioned arrangement of the rod-shaped porcelain polarity switch resistor is that in the corresponding length of the polarity switch resistance l of the insulating cylinder 14, a very large number of polarity switch resistances can be arranged. can be housed in this insulating cylinder.Furthermore, even if air is trapped in the tube-shaped porcelain body, as a result of the porcelain polarity switch taking an inclined position, This air can be evacuated when the tap changer is inserted into the oil-filled transformer vessel.
