Coil structure of open ventilated type stereoscopic wound-core dry-type transformer
A coil structure of open ventilated type stereoscopic wound-core dry-type transformer, comprising wire disks formed by wound wires and fixing parts. The fixing parts are provided with clamping grooves for fixing the wire disks. The wire disks are fixed and wound around the fixing parts to form the coil structure. The outer layers of the wires are coated with insulating paper with insulating paint. And by insulating paint, wires are adhered mutually and wire disks adhere to fixing parts, which combine into an integral structure. The coil structure does not require another paint impregnation process, so the process is simplified. And by the insulating paint on the insulating paper, wires are adhered mutually and wire disks adhere to fixing parts, so the structure is stable and firm and ensures the electrical equipment meets the requirements of electric performance, mechanical property and insulating property.
