Description

Method and device for inserting a winding into adjacent ones Tubes, in particular for current transformers The invention relates to a method and a device for the introduction of turns in pairs next to each other to machine arranged insulator tubes, with the greatest possible elimination the usual manual work. In current transformer construction z. B. is often the task before, in two adjacent tubes made of insulation material copper turns bring in. For this purpose, the required amount of copper conductor was previously from Stock cut off and wound up on boats; the boats were from Hand guided through the pipe openings and so the winding is gradually introduced. The main disadvantages were the expensive, cumbersome manual labor and the fact that that the changing room could not be used to the full, since the shuttle took up space needed when passing through.

The device consists mainly of two suitably spaced mutually arranged rollers with axles mounted in parallel, which are driven by a endless belt (chain) can be driven together by hand or machine. Between The cylinders to be wound are arranged on the rollers with their axes parallel to the plane determined by the roller axes. The process for the two adjacent pipes will be explained with reference to Figs. z to 5.

The required wire is unwound from a supply reel by first laying the beginning through the insulator tube a over the roll b, then through the second insulator tube c over the second roll d. The beginning e is firmly connected to the wire by suitable measures (soldering), so that an endless band is created, which goes over both rollers and is guided through both insulator tubes (Fig. Z).

Are now by suitable drive device, for. B. by the cranks /, the rollers are rotated, the required amount of wire is unwound from the supply roller with the help of this initial loop and winding by winding is placed over both rollers and pulled through the insulator tubes a, c (Fig. A).

Once this has happened, the actual winding of the insulator pair takes place a, c. The end of the supply winding now serves as the beginning of the actual winding. The last applied turn is lifted off one of the rolls and continues to turn the crank pulled by the rest of the supply winding and firmly against one end of the insulator laid (Fig. 3).

The top turn is then removed from the other roll and tightened (Fig. q.).

This process repeats itself until all of the wire goes into the insulator tubes is introduced (Fig.5).

The piece of wire connected to form an endless band can be cut off or be introduced by hand.

Claims (1)

PATENT CLAIM: Method and device for introducing a winding in tubes lying next to one another, in particular for current transformers, characterized in that that on two driven by a common endless belt rollers, which to both sides of the tubes are arranged by turning the rollers as needed Line supply is applied and passed through the tubes to be wound, and that by lifting the topmost turn and further rotation of the role the The final winding of the pair of tubes takes place in such a way that they are turned over the rollers initially shortened to long turns by the train and firmly attached to the ends of the tubes to be wound.
