Definitions
- the invention relates to a tap changer with vacuum interrupters according to the preamble of the first claim.
- Tap changers have been used worldwide for many years to continuously switch between different winding taps of high-speed tap-changers.
- Such tap changer usually consist of a selector for
- the sudden changeover is usually carried out with the aid of a force accumulator, when its triggering a switching shaft is rotated quickly.
- the diverter switch also usually has
- the switching contacts serve for direct connection of the respective winding tap with the load dissipation, the
- Resistor contacts for short-time wiring d. H. Bridging by means of one or more switching resistors.
- Cams have a defined, deviating from the circular contour, by means of the individual switching on the rotation of the shift shaft or also mechanical contacts are actuated.
- the cam is realized here in the form of a horizontally deviating from the circular contour circumferential groove, in the form-fitting engages the respective role. Furthermore, from DE 40 1 1 019 C1 a working on the reactor principle
- vacuum interrupters for regulating power transformers require a high surge voltage capability, up to and significantly above 100 kV. Such unwanted surge voltages, the height of which is substantially due to the structure of the
- Vacuum interrupter such a large stroke, d. H. Distance between the contact surfaces of the corresponding fixed and movable plunger within the vacuum interrupter, to provide that so that the dielectric distances between the contact surfaces of the corresponding plunger are sufficiently large and thus no
- DE 42 31 353 A1 offers no solution here, as by the removal of material to the
- Vacuum switch tube operatively connected actuating lever the required
- the spring has the additional task of initiating the closing force on the actuating lever.
- the spring acts here in a double function for
- the contact force of the contact surfaces of the vacuum interrupter is limited to the spring force of the installed spring, it may also come in a short-circuit stress to a brief lifting of the contact surfaces vacuum interrupter and thus to an electrically undefined state within the power transformer.
- Object of the present invention is therefore to provide a tap changer with vacuum interrupters of the type mentioned above, which has a sufficiently high clamping force of the vacuum interrupter even at short circuit stress, at the same time significantly increased stroke, and also on the resulting material removal over time tolerances significantly reduced the contact system of the vacuum interrupter.
- the general inventive idea consists in addition to the well-known from the prior art rotatably provided on the drive shaft first cam for the introduction of force of the opening stroke of the contact system of the vacuum interrupter,
- movable plunger of the vacuum interrupter exerts and also allows a tolerance compensation of the contact system.
- Main rocker arm having a first leg, on which the first roller is arranged, which at least on a circular sector portion of the end face of the first cam slidges contact-closed.
- two U-shaped further leg are provided on the rocker arm assembly according to the invention on the opposite side of the first rocker on the main rocker between which a likewise rotatably mounted about the axis lever is arranged, at the free end side of the second roller is attached likewise at least on a circular sector section of the front side of the second cam slid contact-closed, wherein between the lever and one of the other legs, a compression spring is arranged. such that thus a spring-lever system is created, which has a sufficiently high clamping force even at
- Short circuit stress exerted on the movable plunger of the vacuum interrupter and also allows a tolerance compensation of the contact system.
- Figure 1 is a schematic representation of a part of an inventive
- FIG. 1 shows a switching shaft 1, which is driven by a spring energy store, also not shown, and at the two parallel spaced, deviating from the circular shape, cams 2 and 3, namely a first cam 2 and a second
- Cam 3 are arranged rotationally fixed.
- the circumferential contours of the two cams 2 and 3 are in the illustrated embodiment substantially star-shaped, but opposite by 180 °, arranged on the shift shaft 1.
- the number of cams used and their circumferential contouring depends on the switching sequence on which the tap changer is based and the necessary sequence
- Vacuum interrupters per phase The description of this Figure 1 is therefore to be taken as an example only for understanding the invention. Of course, according to the essence of the invention, several vacuum interrupters per phase could thus be actuated.
- a typical circuit of a tap changer with a plurality of vacuum interrupters per phase is described by way of example in DE 10 2009 048 813 A1 of the Applicant.
- actuating lever 19 which is guided mechanically linear in its longitudinal direction, for example by a non-illustrated rail.
- a compression spring 20 is provided, which is mechanically supported upwardly, whereas the lower side of the actuating lever 19 is in operative connection with the movable plunger 21 of a vacuum interrupter 22.
- FIG. 1 shows the connected state of the vacuum interrupter 22. Inside the vacuum interrupter 22, therefore, the contact pieces of the movable plunger 21 and the fixed plunger make an electrically conductive connection.
- the front side of the heart-shaped tip of the cam 3 pushes the lever 13 against the spring force of the compression spring 14 in the direction of the other leg 12 via the roller 5, so that the compression spring 14 is under a certain bias and ultimately a closing force on the
- Vacuum interrupter 22 exerts. If it comes in the course of operation of the vacuum interrupter 22 to a material removal at the contact surfaces, it is on the bias of
- Compression spring 14 in cooperation with the further compression spring 20, a tolerance compensation of the rocker arm assembly 6 to the thus changing travel conditions of
- Vacuum interrupter 22 at a certain distance from the end face of the
- Shift shaft 1 rotatably connected cams 2 and 3 rotatably moved.
- the roller 5 comes out of contact with the frontal contour of the corresponding cam 3.
- the roller 4 comes with the frontal contour of the corresponding cam disc 2 in contact, mechanically rolls along this and moves the rocker arm assembly 6 so that upwards, ie opens the contacts of the vacuum interrupter 22.
