Method and device for applying a voltage to a line by means of a Module switch and a switching resistor.

The "invention" relates to a method and one Device for applying a voltage to a high-voltage line. In particular, the invention relates to switching on of sin switch resistors in connection with known module switches for high voltage lines.

It is already known to apply a voltage to a line using resistors, the resistors serve to reduce the electrical oscillations and in particular the overvoltages during the switch-on process dampen.

With regard to switches with multiple sehaltkammers is a method known, according to which during the containment

The closing of the switch-on switches C ₁ , C ₉ , C _x , C. is therefore carried out under current (that is, in a closed circuit or at least in a circuit which, as a result of the closing of the switch-on gate Cj, Co, C ,, O, is closed), co that these switches must have a binary capacity.

The method of the invention shown in 2 is a single switching chamber I- of the switch with several switching chambers (which should also have four chambers) in parallel with a switch-on resistor R ₉ which is in series with an associated on-switch C.

The components that are mounted in the porcelain insulator column 1 are of known design. Within a housing 2 is the switching device according to the invention for performing the various work steps of the method according to the invention.

the fixed contact 9 of the switch in connection. Numeral 10 denotes an insulating agent (for example, air, oil, sulfur-hexafluoride-Sas). The movable contact 11 of the switch is axially inside a cylinder 12 slidably mounted and on his upper end through a recess in a cover 13 of the .. =

Cylinder 12 passed through · Movable on the shaft äe3 Contact 11 is a leather 14 attached and the shaft is connected to a disc 15, which is the leather 14 is more or less compressed according to the position of the contact 11. A tulip-shaped contact 17 is connected to the shaft of the movable contact 11 by springs 16 and forms an electrical connection with a contact carrier 18, which in turn is connected to the connecting member 4.

The switching device used for driving is located inside the housing 2 and consists of cams 19 which are actuated by an outer switching lever 20, a Schiitsplatteneinheit 21 with slides or grooves 22 in which a roller 23 is displaceable, pedals 24, which on a End connected to the fulcrum of the roller 23 and at the other end to the slotted plate unit 21, and a guide rod 25. A common shaft 26, with which the cams 19 are firmly connected, is also connected to the switching device for the contacts of the switching chambers tied together.

The method of operation of the device is intended with regard to switching on a switch with several Schaltkaniaern be explained in a descriptive manner.

At this point the roller 23 is standing with the surfaces "f" of the squat in Touching and moving the crouch 19 counter-clockwise on the crouch without the moving one Relocate contact 11. The surfaces "i" are cylindrical and their axes do not fall the axis of the wall 26 for the squat 19 together.

The squats 19 are rotated until the lever 20 has reached the position "B ^tt at the end of the switch-on ^{stroke and the flat surfaces M} g" assume a vertical position in which they are next to the shaft of the movable contact 11 and the slotted plate unit 21 are located. The position of the squat 19 and the Schiitzplattenein.-unit 21 during this work step is in the year. 3 represented by a dash-dotted line. All contacts of the various chambers of the switch are closed at the same time.

the position indicated by the dash-dotted line has been reached, the roller 23 of the slotted plate unit 21 is at the upper end of the surfaces ^M g "of the hooks 19 (whereby it has gone beyond the edge between the surfaces f and g) and the slotted plate unit

unit 21 can return to their starting position, ^in-1 and thereby to return the movable-contact in the Üffnungsstellung under the action of the compressed spring 14 during the closing operation again. While the contacts 11 and 11 open, the roller 23 slides along the surfaces g without necessarily being in engagement therewith.

It should be noted that when the contacts 9 and 11 are opened, a practically insignificant current is interrupted, as this is caused by the parallel connection between the closed contacts of the switching chamber connected to the switching device described above ' and the resistor R connected in series with the on-switch is determined. Dalier does not need the Binary switch has a disconnecting capability or, as already stated, a disconnecting capability.

The guide rod 25 prevents the movable contact 11 from rotating about itself and furthermore prevents the roller 23 from shifting along the slots or hats 22 when the assembly consisting of roller 23 and slot plate unit 21 is in the upper position, in which the contacts 9 and 11 are closed. If the contacts of the switch with several switching chambers are opened in order to de-energize the line, the socks 19 are returned to their original position.

To at the Opening the contacts does not prevent the cams 19 from moving in the opposite direction. This is the length of the Guide rod 25 dimensioned so that the fulcrum of the Roll 23 along the slots or hats 22 of the slot plate assembly 21 can move in a direction perpendicular to the axis of the movable contact 11 when the. movable contact 11 of the switch in the open position is located.

The embodiment described above can obviously be modified or further developed without leaving the scope of the invention.
