良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a power supply circuit device in a wire current heating device for uniformly heating a large diameter wire to a predetermined temperature over its entire cross section with a large current at a low frequency such as a commercial frequency.

るを得なかつた。 For example, while running a large wire rod with a diameter of 8 to 15 mm, a low frequency such as a commercial frequency and a large current of 1000 to 2000 A are applied to the wire rod by multiple contact rolls, and the wire between the contact rolls is In order to supply heating power when uniformly heating the entire cross section of the contact roll to a predetermined temperature, if you try to keep the impedance low, the power supply circuit from the power supply E to the power supply box S of the contact roll C, as shown in Figure 1a, is connected to the power supply E. After reaching the vicinity of the wire feeding path, bend it and install the power supply box S close to and parallel to the feeding path.
If the bus bar B is configured to connect to
The electromagnetic force acts and induces mechanical vibration in the direction of arrow a←→b in the wire W being fed, which makes the contact between the contact roll and the wire W unstable, causing the wire W to be unevenly heated or caused by sparks. It may leave a scar. To avoid this, conventionally, as shown in Figure 1b, the busbar B had to be configured to be sufficiently far away from the wire feed path, knowing that reactive power would be large and dust would be generated due to increased impedance. I didn't get it.

給電回路装置を提供するものである。 This invention is a new method that prevents the large reactive power loss that exists in conventional power supply circuit devices and eliminates the generation of mechanical vibrations when a large diameter wire is uniformly heated over its entire cross section to a predetermined temperature using a low frequency large current such as a commercial frequency. The present invention provides a power feeding circuit device.

取付けて当該管状導体を冷却してもよい。 A known bus bar B is arranged at the shortest distance from the power source E to the wire feeding path. In the present invention, a tubular conductor denoted as PB is arranged between the end of the bus bar B in the wire feeding path direction and the power supply box S of the contact roll C so as to be coaxial with the wire feeding path. As with the bus bar B, the tubular conductor PB is preferably made of a highly conductive material such as a copper tube. If the tubular conductor PB is arranged in this way, the current flowing through the tubular conductor PB at a certain moment and the wire W
Since the wire W and the tubular conductor PB are coaxially arranged as shown in Fig. 2b, the electromagnetic mechanical force due to the magnetic flux of different polarity generated by each current flowing through the machine is balanced. Therefore, no vibration is induced in the wire W. Note that, if necessary, a cooling pipe through which cooling water flows may be attached to the outside of the tubular conductor PB to cool the tubular conductor.
