Abstract

PURPOSE:To detect where a short-circuit happened between turns without temporarily stopping a winding machine by detecting the short-circuit between turns and layers constantly measuring the resistance of a superconductive wire during winding operation. CONSTITUTION:Both the ends of a superconductive wire 6 and led from the inside holes of the innermost layer of the coil drum 3 of a coil frame 1 respectively and connected to the rotating terminals of a slip ring 7. Since the superconductive wire at a normal temperature has rather greater electric resistance per unit length than the resistance of an ordinary wire, a short-circuit between layers or turns can be detected by the reduction of resistance if the short-circuit is occurred by measuring the resistance of the superconductive wire at the output terminal of the slip ring 7 during winding operation. Normally, a slip ring has terminals of two pairs or more and the distortion of a coil frame, etc. are also simultaneously measured using the remaining terminals.

Moreover, with this measurement, it is not clear at what position the inter-turn shift occurred.

The purpose is to provide a winding machine that can be detected.

することができる。An example is shown in FIG. Both ends of the superconducting wire 6 exit from the innermost layer of the coil winding frame 1 and the inner hole of the winding drum 3, respectively, and are connected to rotating terminals of a slip ring 7. Superconducting ll1i kept at room temperature exhibits an electrical resistance value per unit length that is considerably higher than that of ordinary conductive wires, so the winding work is carried out while measuring the resistance value of the superconducting wire from the output terminal of slip ring 7. By advancing, between the eyebrows,
Also, if a sheet occurs between the turns, this can be detected by a decrease in the resistance value. Also, since a slip ring for normal measurement has two or more pairs of terminals,
The remaining terminals can be used to simultaneously measure the strain on the winding frame.
