Auto-type resistance furnace transformer

DetailsAuto-type resistance furnace transformer as a regulating resistance furnace power, for the transformer design is more economical and reasonable use of auto-type structure, resistance furnace voltage is generally higher than the salt-bath furnace. Auto-type resistance furnace transformer for rated frequency 50HZ of the AC line as a resistance furnace heating voltage regulation purposes.Core: Using 0.3mm thick high-permeability properties of silicon steel sheet, 45 ° full-oblique joints, three step-lap, no punching, surface coating to core insulating paint, moisture-proof rust, loss of small, low noise. Multi-step-shaped core columns with circular cross section. Core yoke with rectangular cross section, with steel and screw fastening core. Coil: coil made of cylindrical inner and outer generally made of spiral type, turn to turn insulation pads off, and after several VPI vacuum pressure impregnation equipment, solvent-free impregnating H-class paint baking at high temperature cure, to make an excellent moisture resistant, better able to withstand thermal shock, never cracking, the life period is easy to decompose recycling, environmental protection. Shell: transformers, protective cover, and there may be a cause of lifting the body of the whole rings.
