Abstract
The utility model discloses an energy-saving transformer employing a stereo wound core. The energy-saving transformer employs a stereo wound core, wherein a three-phase magnetic circuit of the stereo wound core is symmetrical. Coils are sleeved on the stereo wound core and comprise a fixed coil and a low-voltage coil, wherein the low-voltage coil and the fixed coil are in electrical connection and are concentrically placed to form a high-voltage coil. The number of turns of the fixed coil is w4, the number of turns of the low-voltage coil is w, and the number of turns of the high- voltage coil can be calculated as follows: W is equal to w plus w4, and the position of a neutral point of the low-voltage coil can be adjusted to change the number of turns of the low-voltage coil. The fixed coil and low-voltage coil can be arranged in an axial direction and distributed up and down to form the high-voltage coil. According to the utility model, the energy-saving advantages of the stereo wound core such as a three-phase balance, a small harmonic wave, a no-load current and a low no-load loss can be brought into full play. Combined with the energy-saving advantages of the stereo wound core and the neutral point of the variable flux of the coil, the low no-load loss is enabled to substantially reduce when a relative high voltage is outputted, and an energy-saving effect is well achieved. According to the difference between output voltages, specification of a guiding wire can be selected in a multi-step mode to manufacture the low-voltage coil and manufacturing cost can be reduced.
