Abstract

PURPOSE:To cool a cable efficiently, by placing a mat for flowing refrigerant between winding layers of a power feed cable. CONSTITUTION:A power feed cable 1 is wound around the drum of a reel 2, and a mat 4 for flowing refrigerant is placed between the winding layers of the cable 1. The mat 4 has rectangular shaped with the width thereof slightly narrower than that of the drum 3 of the reel 2, and many paths communicating over the entire width are provided with proper intervals in longitudinal direction. The reeled power feed cable 1 is used while being immersed in a cooling tank 5. In such arrangement, refrigerant flows through the refrigerant flow paths in the refrigerant flow mat 4 and cools the power feed cable.

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for winding a power supply cable for a mobile object onto a reel.

[Prior art and problems to be solved by the invention] Cables are generally used after being unwound from the drum or reel on which they are wound, but they are used for power supply to cranes, underwater bulldozers, etc. In the power supply cable for a mobile object, the distance between the device to be powered and the power source varies, so that the cable is energized while remaining wound on the reel.

ある。
The biggest problem in this case is that when electricity is applied to a cable that is wound in multiple layers and in multiple rows on a reel, the Joule heat generated is difficult to dissipate to the outside, so the cable temperature at the center of the wound layer increases significantly. It's about putting it away. That is, as shown in FIG. 3, assuming that the reel is composed of both flange plates 102 and the winding drum 3, the central part of the winding layer separated from both flange plates 102 is the hatched area shown by C in the same figure). In this case, the temperature of the cable becomes particularly high, resulting in the inconvenience that the actual current flowing through the cable becomes much smaller than the allowable current value of the cable.

As a countermeasure to this problem, it is conceivable to use larger cables that take into account the current reduction, but in this case, the cables will become larger and heavier, resulting in increased costs and difficulty in handling. can avoid the decline in
Moreover, this solution cannot be applied to power supply cables for mobile objects related to ocean development because there are restrictions on both the outer diameter and weight of the cables.

Under these circumstances, in the past, a cooling medium such as air or water was directly sprayed onto the reeled power supply cable for a moving body, or the power supply cable for a mobile body, together with the reel, was immersed in a cooling medium in a cooling tank. A method of soaking and cooling is used, but in this case as well, the cable is tightly wound around the reel in multiple layers and rows, so the cooling medium is
It was not possible to reach the central region of the winding layer shown in , and a sufficient cooling effect could not be achieved.

First, in carrying out the method of the present invention, as shown in FIG. 1, a large number of cooling medium flow passages 21 are formed on the inner surface of each collar plate 2, extending radially from the body to the outer edge thereof. A reel 2 and a cooling medium distribution mat 4 separate from the reel 2 are used.

The cooling medium distribution mat 4 has a rectangular plate shape with a width slightly narrower than the width of the windings 3 of the reel 2, and cooling medium flow passages 41 that communicate over the entire width are spaced at appropriate intervals in the longitudinal direction of the mat. There are a large number of them, and they are made of flexible synthetic resin or hard rubber, or a chain of many metal strips connected so as to have flexibility as a whole.

The reel winding method of a power supply cable for a mobile object according to the present invention using these reels 2 and cooling medium distribution mats 4 is as follows:
As shown in FIGS. 1 and 2, this is a method in which a cooling medium distribution mat 4 is interposed between winding layers of a power supply cable 1 for a movable body wound around a reel 2. This can be easily accomplished by winding the cooling medium distribution mat 4 together with the cable 1 onto the reel 2 as shown in FIG.

The movable body power supply cable 1 wound into a reel as described above is actually used while being immersed in a cooling tank 5 as shown in FIG. Cooling medium 6, normally water is on the collar plate 2
The cooling medium flows inward in the radial direction of the collar plate 2 through the cooling medium flow passages 21 of the cooling medium distribution mat 4, and then flows in the axial direction of the winding drum 3 via the cooling medium flow passages 41 of the cooling medium distribution mat 4. The cooling medium 6 can spread to the center region C of one winding layer. In this case, no matter how tightly the cable 1 is wound, the circulation paths of the coolant flow paths 21 and 41 will not be blocked, so that the circulation of the coolant 6 in the cooling tank 5 is guaranteed.

If the cable is wound on a conventional ordinary reel and the cable is not cooled, the above value is only 10, and even if it is water-cooled in a cooling tank, the above value is about 16.
When the cable is wound on a reel by the method of this invention and the cable is water-cooled in a cooling tank, the above value is approximately 50%.
A significant improvement was seen.

[Effects of the Invention] According to this invention, a reel is used in which a large number of coolant flow passages extending in the radial direction are provided on the inner surface of the collar plate, and when winding the power supply cable for a moving body onto the reel, A cooling medium distribution mat having a cooling medium flow path extending in the direction of the axis of the reel body is interposed between the cable winding layers.
When this reel-wound power supply cable for a moving object is cooled in a cooling tank during use, the cooling medium passes through the cooling medium flow path on the inner surface of the collar plate and the cooling medium flow path on the cooling medium flow mat, and the cooling medium flows through the cable winding layer. It can reach the central area and effectively cool the cable. Therefore, the current value that can be passed through the power supply cable for a mobile object can be significantly increased compared to the conventional one.
