Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to a water-cooled cable for a medium-frequency furnace that can shield electromagnetic fields. Background Technology

[0002] In the process of producing metal powder using the water atomization method, solid metal materials are fed into an intermediate frequency furnace to melt and form a molten metal or alloy. The intermediate frequency furnace uses an intermediate frequency power supply for induction heating. Three-phase AC power is rectified and inverted into a 500Hz-20000Hz intermediate frequency current through an intermediate frequency cabinet. This current then passes through a copper coil inside the furnace to create a magnetic field. The magnetic field induces eddy currents in the metal material within the coil. These eddy currents flow through the heated metal material, generating heat and thus achieving the purpose of melting the metal. This invention utilizes related water-cooled cables, strip-shaped conductive rubber, and carbon-free insulating tubing. Strip-shaped conductive rubber is used on the surface of the original water-cooled cable's carbon-free insulating tubing, tightly wrapping it in a circular manner. This effectively shields the electromagnetic field generated by the water-cooled cable after the intermediate frequency current is connected, reducing electromagnetic interference to other electrical signal acquisition systems around the intermediate frequency furnace and preventing electromagnetic interference between the two water-cooled cables, thus providing a certain degree of protection for surrounding electronic and electrical equipment. Utility Model Content

[0003] This invention provides a water-cooled cable for a medium-frequency furnace that can shield electromagnetic fields, with the aim of solving the problem of electromagnetic interference between two water-cooled cables.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A medium-frequency furnace water-cooled cable that can shield electromagnetic fields uses strips of conductive rubber tightly wrapped around the surface of the first carbon-free insulating tube of a conventional water-cooled cable. A second carbon-free insulating tube is then wrapped around the conductive rubber. The grounding device is connected to the conductive rubber, effectively shielding the electromagnetic field generated by the water-cooled cable after the medium-frequency current is connected, and avoiding mutual interference between water-cooled cables.

[0006] This water-cooled cable can shield the electromagnetic field generated by the intermediate frequency current. The cable uses strips of conductive rubber tightly wrapped around the outside of the carbon-free insulating tubing to prevent contact with the copper strands. This use of conductive rubber prevents damage to the conductive rubber caused by folding or bending during the intermediate frequency furnace's turning process. The additional layer of carbon-free insulating tubing further protects the conductive rubber from friction and wear against equipment.

[0007] The strip-shaped conductive rubber has a cross-section of 20mm wide and 5mm high parallelogram, which can be tightly wrapped around the water-cooled cable.

[0008] The beneficial effects of this utility model are as follows:

[0009] Strips of conductive rubber are used to tightly wrap around the surface of the original carbon-free insulating tubing of the water-cooled cable. This effectively shields the electromagnetic field generated by the water-cooled cable after it is connected to the intermediate frequency current. This reduces electromagnetic interference to other electrical signal acquisition systems around the intermediate frequency furnace and avoids electromagnetic interference between the two water-cooled cables, thus providing a certain degree of protection for surrounding electronic and electrical equipment. By grounding the strips of conductive rubber through a grounding device, it simultaneously provides both electric and magnetic field shielding. Wrapping the conductive rubber with carbon-free insulating tubing effectively protects the conductive rubber layer and prevents mechanical wear caused by the intermediate frequency furnace's rotation process.
