Definitions

  • the invention relates to an on-load tap changer module for on-load tap changers.
  • On-load tap changers are known from the prior art and usually have a diverter switch and a selector.
  • the diverter switch with the vacuum interrupters and the transition resistors is arranged in a cylindrical vessel.
  • the selector is made up of a large number of sticks arranged in a circle. Contacts are arranged on different levels on these bars, which serve as connections for a control winding. Inside the selector, two selector arms are attached to a switching column. These make contact with the contacts on the rods.
  • Diverter switch and selector are connected to each other via a gear.
  • the motor drive is located on the outside of the step-up transformer and is connected to the on-load tap-changer via a linkage. This structure requires a lot of space, is complex and expensive.
  • the invention proposes an on-load tap changer module for on-load tap changers, comprising:
  • the diverter switch, the selector and the preselector are arranged on the carrier and are operated centrally by the drive module.
  • the design of the on-load tap changer module enables central actuation of all parts via a common drive module.
  • the drive module is arranged in the middle, i.e. centrally between diverter switch, selector and preselector. In other words, the drive module is surrounded by the diverter switch, selector and preselector.
  • the central actuation by the Drive module a precise implementation of all switching.
  • the carrier can be designed in any way and be produced, for example, as a plate or plate-shaped injection molded part.
  • the carrier can be made of plastic, glass fiber reinforced plastic or any other electrically insulating material.
  • the diverter switch can be designed in any way and have, for example, one or more vacuum interrupters and one or more bridge switches.
  • the bridge switch can be actuated by a linear or rotary movement.
  • the selector can be designed in any way and can have, for example, one or more selector arms.
  • a selector arm can be designed in any way and can be designed, for example, as a Geneva wheel or a gear wheel.
  • the selector has a plurality of selector contacts which can be designed, for example, in a T-shape or L-shape, so that on the one hand they extend from one side of the carrier to a second side of the carrier and on the other hand they protrude to a side wall of the carrier, where they connect to the winding taps be connected to a control winding.
  • the first side of the carrier is arranged opposite the second side of the carrier.
  • the drive module can be designed in any way and consist, for example, of a drive shaft and at least one actuating element.
  • the drive shaft and the actuating element can be designed in one or more parts.
  • the actuating element can be designed as a gear wheel, cam contour, part-toothed gear wheel, driver or double driver.
  • a plurality of actuating elements can be arranged on or on the drive shaft.
  • the several actuating elements can be configured in one piece or in multiple pieces.
  • the actuating elements can be connected to one another, for example, by gluing, screwing or plugging.
  • Each actuating element can be designed in any way and directly or indirectly actuate or drive selectors or preselectors, diverter switches or parts thereof.
  • one actuator can operate multiple elements such as a selector and a preselector.
  • several actuating elements can actuate a selector, in particular a first selector arm and a second selector arm.
  • the drive module can be formed in any manner and substantially central in the middle of the carrier, surrounded by the selector, preselector and Diverter switch, be arranged.
  • the drive module can be arranged centrally, ie in the geometric center of the carrier, or approximately in the geometric center of the carrier.
  • the on-load tap changer can be designed in any way as required and can be designed, for example, as a high-speed resistance switch or reactor switch.
  • FIG. 1 shows a first side of an on-load tap changer module
  • FIG. 2 shows a drive module for the on-load tap changer module
  • FIG. 3 shows a second side of the on-load tap changer module
  • Figure 4 is a detailed view of a preselector
  • FIG. 5 shows an on-load tap changer with three on-load tap changer modules.
  • FIG. 1 shows an on-load tap changer module 1 according to the invention for an on-load tap changer 9.
  • the on-load tap changer module 1 has a carrier 2 which consists of a plastic, glass fiber reinforced plastic or another electrically insulating material.
  • This carrier 2 is either in the form of a milled part or is produced by means of an injection molding process.
  • a first page 2.1 of the carrier 2 is a first selector arm 11 of a voter
  • the first selector arm 11 is rotatably mounted and rotates about a selector axis 19 . Furthermore, the first selector arm 11 carries at least one first sliding contact 12.
  • the selector 10, ie the first selector arm 11, selector contacts 18 are arranged in a circle.
  • the selector contacts 18 are designed such that they extend on the one hand from the first side 2.1 of the carrier 2 to the second side 2.2 of the carrier and on the other hand are guided to a first side wall 5 of the carrier 2. Described specifically, the selector contacts 18 are T-shaped or L-shaped.
  • the bridge switch 25 has a housing with contacts attached thereto. Farther the bridge switch 25 has several fixed contacts. The fixed contacts are attached to the carrier 2 and also protrude from the first side 2.1 of the carrier 2 to the second side 2.2 of the carrier 2. The housing is connected to a gear wheel via a connecting rod. The contacts on the housing of the bridge switch 25 are connected to a load diverter.
  • a drive module 30 is arranged on the carrier 2 .
  • This has, among other things, a drive shaft 31 which is designed as a hollow or solid square shaft made of plastic.
  • the drive shaft 31 also extends from a first side 2.1 of the carrier 2 to a second side 2.2 of the carrier 2.
  • the drive module 30 is arranged essentially between the selector 10 and the diverter switch 20.
  • actuating elements are arranged on the drive shaft 31, as shown in Figure 2, in particular a first driver 32, a cam driver 34 and a drive gear 35.
  • the first actuating element i.e. the first driver 32, actuates the first selector arm 11 of the selector 10.
  • the fourth actuating element i.e. the drive gear 35, actuates the bridge switch 25 of the diverter switch 20.
  • the third actuating element, i.e. the cam driver 34 actuates a vacuum interrupter 21 of the diverter switch 20.
  • FIG. 3 shows the second side 2.2 of the carrier 2.
  • the second selector arm 15 of the selector 10 is arranged here.
  • the second selector arm 15 is also designed as a Geneva wheel.
  • the second selector arm 15 is rotatably mounted and also rotates about the selector axis 19 .

  • the selector 10, ie the second selector arm 15, selector contacts 18 are arranged in a circle.
  • the selector contacts 18 are designed such that they extend on the one hand from the second side 2.2 of the carrier 2 to the first side 2.1 of the carrier and on the other hand are guided to a first side wall 5 of the carrier 2.
  • the selector contacts 18 are T-shaped or L-shaped.
  • the vacuum interrupter 21 of the diverter switch 20 is arranged on the second side of the carrier 2 2.2. This is fixed on the carrier 2 by means of a bearing block, among other things.
  • a switching resistor 4 is arranged on the second side 2.2 of the carrier 2 and is connected to the on-load tap changer module 1 via a connecting element 3 .
  • a preselector 40 is also arranged on the second side 2.2 of the carrier 2.
  • This has a selector arm 41, which is also designed as a Geneva wheel.
  • the first preselector arm 41 is rotatably mounted and also performs a rotary motion about the preselector axis 44 .
  • the preselector 40 has a preselector rocker 42 which can switch between two preselector contacts 43 by a pivoting movement.
  • another part of the drive module 30 is arranged on the carrier 2 . This has the drive shaft 31 already mentioned.
  • the drive module 30 is arranged essentially between the selector 10, the diverter switch 20 and the preselector 40.
