Ways to carry out the invention

Fig. 1 shows schematically a separator module according to the invention in closed state in partial section. The separator module is provided as Part of a high-power switch, in particular a high-current switch or generator switch. The separator module has a Disconnector drive housing 10a and a quenching chamber drive housing 10b and a separator tube 1 1. The isolator module is part of the active part of the Heavy-duty switch, and the two drive housings 10a, 10b are on Insulators 13,14 mounted on a base plate 15, which is located on Ground potential is located.

The separator tube 11 serves to generate a visible separation path. The Separator tube 11 is by means of a schematically indicated drive 12th along an axis movable parallel to one in Fig. 1st shown longitudinal x runs. Im in Fig. 1 shown closed state of the separator module is the separator tube 11 at its both ends in electrical contact with contact finger modules 1. At the Disconnector drive housing 10a and on the quenching chamber drive housing 10b are each along a circumference of the respective drive housing 10a, 10b arranged a plurality of contact finger modules 1. The Contact finger modules 1 each contain at least one contact finger 2 with a contact piece 4 and at least one leaf spring 3. Dle Contact finger modules 1 are shown in Figs. 2 and 3 described in more detail.

To produce the visible separation line, the separator tube 11 moved against the longitudinal direction x, so that the extinguishing chamber drive housing-side contact finger module 1 no longer in electrical contact with the separator tube 11 and are sufficient Gap between the drive chambers 10a, 10b is shown. The Leaf springs 3 cause a contact pressure in the closed state, by which the contact pieces 4 are pressed against the separator tube 11.

To close the separator module, the separator tube 11 in Longitudinal x moves so that both the separator drive housing side as well as the quenching chamber drive housing side contact finger module 1 Contact the separator tube 11.

As can be seen from FIG. 1, the separator tube 11 Separator drive housing side along the longitudinal direction x advantageously a rounded stepped outer diameter on. The Separator drive housing side contact finger module 1 are also in opened state in electrical contact with the separator tube 11; the Separator drive housing side contacts 4 are then on the Separator tube 11 reduced in one area Separator tube outer diameter supported. The leaf springs 3 have in this state, a mechanical bias, by means of which the Contact pieces 4 are pressed against the separator tube 11. A deep one Ratio of this mechanical bias to the contact pressure with which the contact pieces 4 in the closed state of the Leaf springs 3 are pressed against the separator tube, is very advantageous thereby a reduced insertion force for the separator tube 11 when switching and a reduced abrasion of the contact pieces 4 at a sufficiently large Contact pressure is present. By a particularly far contacting end-side arrangement of the place of introduction of force the leaf spring 3 in the contact fingers 2, said ratio is low. With respect to the quenching chamber driving case side contact finger module 1 means a particularly far contacting end-side arrangement of the Place the application of force from the leaf spring 3 in the contact fingers 2 at given contact pressure a reduction of the mechanical retraction resistance when closing the circuit breaker. Because in this case, too is the ratio of a caused by the leaf springs 3 mechanical Bias voltage to the contact pressure small.

All contacts 4 learn when closing the separator module a Deflection along a deflection, which radially outward is directed and thus aligned perpendicular to the longitudinal direction x. Contact forces to effect appropriate contact pressures are per Contact piece 4 typically between 20 N and 40 N, in particular between 25 N and 35 N. Corresponding preload forces are per Contact piece 4 typically between 10 N and 20 N, in particular between 12 N and 18 N.

A high power switch according to the invention can be a disconnector module such as include that shown in Fig. 1, wherein then advantageously the Isolator drive housing 10a is arranged on the mains side, while the Extinguishing chamber drive housing 10b with a not shown Arcing chamber is connected, which is arranged on the generator side.

Contact finger modules 1 according to the invention are also available at others Switch points or contact points can be used in high-performance switches, for example, in the quenching chamber or otherwise preferably in Rated circuit, especially in combination with burn-off resistant Contact parts.

In Fig. 2, a contact finger module 1 according to the invention is corresponding one of the contact finger modules 1 shown in Fig. 1 mounted in the Condition shown in section. The contact finger module 1 is on the only indicated disconnector drive housing 10a by means of a Screw 9 fixed, which at the same time the leaf spring 3 at the contact finger 2, or more precisely a flexible contact piece carrier 5 of the Contact finger 2, fixed. The ends 31,51 of the leaf spring 3 respectively the flexible contact piece carrier 5, to which the leaf spring. 3 or the flexible contact piece carrier 5 on the Heavy-duty switch is mounted as fixing ends 31,51 designated. As a fastener receiving 7,8, the leaf spring. 3 and the contact piece carrier 5 each have a bore 7,8. The flexible one Contact piece carrier 5 extends along the longitudinal direction x and has also an extension along the designated z Direction of deflection. This is optional, is advantageous by one or two kinks or bends of the contact piece carrier 5 is caused and is preferably aligned counter to the deflection z.

At a further end 52 of the contact piece carrier 5, which as Konktaktierungsende 52 is designated, the contact piece carrier 5 with the contact piece 4 vebunden. This projects beyond the contact piece carrier. 5 against the deflection z. The connection between the Contact piece carrier 4 and the contact piece 4 is advantageous by a Tumble connection 6, also referred to as radial rivets 6 formed. Other positive, positive or cohesive connections are also possible. A Washer 6a can between the flexible contact piece carrier 5 and be arranged the head of the radial rivet 6.

The contact piece 4 is used to make contact with a second, not illustrated contact piece, which relative to the contact finger module. 1 along the longitudinal direction x is movable and a detachable electrical Contact with the contact piece 4 can form (in the closed state). In the structure of Fig. 1, this second contact piece of the Separator tube 11 is formed. To form the electrical contact (Switching) learns the contact piece 4 due to the relative movement of the Contact pieces along the longitudinal direction of a deflection in the to Longitudinal direction x vertical deflection direction z. The contact piece 4 is made made of material of high electrical conductivity, in particular of copper, which advantageously has a silver coating.

The flexible contact piece carrier 5 is advantageous as a disk pack educated. The slats are made of high electrical material Conductivity and may have an electrically conductive coating. Preferably, the fins are made of copper and have advantageous a silver coating on. The individual slats are advantageous similarly formed and have a thickness of typically between 0.1 mm and 0.7 mm, preferably between 0.15 mm and 0.3 mm, on. On This way, a suitable elastic deformability of the flexible Contact piece carrier 5 can be achieved with high electrical conductivity.

The preferred metallic, in particular steel leaf spring 3 is on the the contact piece 4 side facing away from the flexible contact piece carrier. 5 arranged. Except at its end 32 it is formed without bending and extends advantageously, as shown in Fig. 2, along the Longitudinal x. At its end 32, the leaf spring 3 against the Deflection direction z bent by more than 180 °. She could also be around be bent a less large angle. The last piece of the end 32 the leaf spring 3 closes with the axis of the longitudinal direction an angle α which is advantageously at least 5 ° or at least 10 °.

Due to the bending by more than 180 °, a secure support of the leaf spring 3 on the contact finger 2 and a long lever arm for the leaf spring 3 can be achieved. With respect to the longitudinal direction x, the support and force introduction point of the leaf spring 3 is at a longitudinal coordinate designated as x _F , which is farther from the attachment end 31 than the longitudinal coordinate x _{1 of} the center of the contact piece 4.

In the longitudinal direction x, the leaf spring extends to a longitudinal direction coordinate x _L. This is arranged in Fig. 2 on the mounting end 31,51 facing away from a longitudinal direction coordinate x ₁ , which denotes the center of the extension of the contact piece 4 in the longitudinal direction. Moreover, x _{L is} disposed on the side of a longitudinal direction coordinate x ₀ facing away from the attachment end 31, 51, which designates the end of the extension of the contact finger 2 in the longitudinal direction.

The contact piece 4 does not necessarily terminate flush in the longitudinal direction x with the contacting end 52 of the contact piece carrier 5, as shown in FIG. The contact piece 4 may protrude beyond the contact piece carrier 5 in the longitudinal direction x or be surmounted by this. However, the contact piece 4 is arranged at the contacting end 52 of the contact piece carrier 5, and its longitudinal extent is a good measure of the size of the contact finger module 1. A good field control effect of the leaf spring 3 is already achieved when the leaf spring 3 in the longitudinal direction x to at least the center x _{1 of} the extension of the contact piece 4 in the longitudinal direction x extends.

There is no need for the leaf spring 3 on one Isolate insulation plate instead of directly on the contact finger 2. Experiments and simulations have shown that branch streams, which through the leaf spring 3 from the attachment end 31 through the leaf spring 3 flow into the contacting end 52 of the contact finger 2, not to a cause such a large warming of the leaf spring 3, that this in relevant Lose mass of spring force.

The leaf spring 3 can also be bent in the direction of the deflection z (not shown). Then a bend of at least 180 °, like too greater than 270 °, advantageous to achieve good field control. In in the case of a bending of the leaf spring 3 at its end 32 in the direction of Auslenkrichtung z, the leaf spring 3 can be advantageous between their Ends 31,32 be bent against the deflection z and / or himself there (partially) extend against the deflection z, and at the Befestigungsende 31,51 can advantageously between the leaf spring 3 and the Contact piece carrier 5 a spacing means (not shown) arranged be to apply the contact pressure by the leaf spring 3 on the To simplify contact fingers 2.

The contact finger module 1 according to FIG. 2 can be one, two, three or more Contact fingers 2 and leaf springs 3 have. The most advantageous Embodiment with two contact fingers and leaf springs is shown in Fig. 3rd shown.

FIG. 3 shows a view of the corresponding contact finger module 1 according to FIG Fig. 2 from that in Fig. 2 with "III" direction. There are two Contact fingers 2,2 ', each with a flexible contact piece carrier 5,5' and each a contact piece 4,4 'exhibited and two with the Contact fingers 2,2 'in the manner described above cooperating Leaf springs 3,3 '. The two contact fingers 2,2 '(or more precisely: the two Contact piece carrier 5.5 ') advantageously have a common Fastening 51 on. And also the two leaf springs 3,3 'have advantageously a common attachment end 31 (not in Fig. 3) visible, noticeable).
