Product Brief
    Autotransformer may serve as a regulator, lighting and power supply voltage of electric resistance furnace. In order to make the transformer design more economical and reasonable can be adopted self-coupling type structure, such as resistance furnace power supply is generally lower than the salt bath furnace is high, such as ZUSOG, ZUDOS type resistance furnace transformer 380 volt AC power, through the autotransformer connection after the change of all kinds of voltage transformer.
    Function characteristics
    Transformer coil inner layer made of self coupling type, cylindrical, outer general with bare wire made of spiral type, turn-to-turn with cushion block for insulation are separated, the inner layer and the outer layer coil with air for cooling and insulation, high pressure head connected to the terminal to switch on the power supply. Core uses core type consists of cold rolled silicon steel sheet stacking and adopts multistage ladder Park section of iron, iron yoke with rectangular cross section, the steel and screw fastening, transformer generally no shell body is provided with a hanging ring, is capable of lifting the entire body.
    The temperature control device:
    Transformer using BWDK series signal thermometer, temperature measuring elements embedded in the low voltage coil half, can automatically detect and touring shows three-phase coil respective working humidity. And over-temperature alarm and tripping function.
    Range of application
    Self coupling type resistance furnace transformer applies to rated frequency of 50 Hz 380 V AC line as resistance furnace heating regulating voltage of.
