The invention relates to the technical field of transformers, in particular to an isolation transformer. The isolation transformer comprises an expander, an oil storage cabinet, a silicon rubber sleeve, an oil tank and a transformer body, wherein the bottom of the expander is connected with the top of the oil storage cabinet, the bottom of the oil storage cabinet is connected with the top of the silicone rubber sleeve, the bottom of the silicone rubber sleeve is connected with the oil tank, and the device body is arranged in the silicone rubber sleeve and the oil tank; the transformer body comprises a capacitive screen sleeve, a high-voltage coil, a shielding electrode and insulating paper, the capacitive screen sleeve is connected with the shielding electrode, the high-voltage coil is arranged in the shielding electrode, and the insulating paper wraps the outer side of the capacitive screen sleeve and the outer side of the shielding electrode. The isolation transformer is high in voltage tolerance, uniform in electric field and high in interference signal shielding capacity; the high-voltage coil is distributed outside an inner low-voltage coil, so that the overall size of the transformer is small, the heat dissipation performance is good, and in order to facilitate transportation of the transformer, an iron core in the oil tank can be mounted by using a horizontal structure.
Description
technical field [0001] The invention relates to the technical field of transformers, in particular to an isolation transformer. 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 high-frequency clutter from entering the control loop. Using an isolation transformer to suspend the secondary to the ground can only be used in occasions where the power supply range is small and the line is short. At this time, the capacitance current of the system to gro...
