The invention relates to the technical field of transformers, and specifically discloses an isolation transformer body. The body is arranged on an iron core. The body includes a capacitive screen sleeve, a high-voltage coil, a shielding electrode and insulating paper. The shielding electrode is connected, the high-voltage coil is set in the shielding electrode, the insulating paper is wrapped on the outside of the capacitive screen casing and the shielding electrode, and the iron core is wound with a low-voltage coil, and the low-voltage coil is set in the the outside of the insulating paper. The body of the isolation transformer of the present invention adopts the arrangement of high-voltage coils inside and low-voltage coils outside, and uses shielding electrodes to separate the high-voltage coils from the low-voltage coils, so as to better withstand the main insulation, uniform electric field and shield interference signals. Moreover, the body of the invention is small in size and has good heat dissipation performance. In order to facilitate the transportation of the transformer, the iron core in the oil tank can be installed in a horizontal structure.
Description
technical field [0001] The invention relates to the technical field of transformers, in particular to an isolation transformer body. Background technique [0002] Isolation transformer refers to a transformer with electrical isolation between the input winding and the output winding. The isolation transformer is used to avoid accidental contact with the live body at the same time. The isolation of the transformer is to isolate the respective currents of the primary and secondary coils. [0003] The main function of the isolation transformer is to completely insulate the primary side from the secondary side and also isolate the circuit. In addition, the high-frequency loss of the iron core is used to suppress the high-frequency clutter from entering the control circuit; the isolation transformer is used to suspend the secondary to the ground, which can only be used in occasions where the power supply range is small and the line is short. At this time, the capacitance current...
