technical field [0001] The invention belongs to the technical field of transformers, in particular to a high-temperature superconducting high-voltage transformer and its application as a low-current high-voltage power supply. Background technique [0002] Due to the high internal resistance and low current conduction density of the transformer coil wound by traditional copper wires, when the secondary coil of the high-voltage transformer needs to generate a very high output voltage, the power consumption of the primary coil is large, and the The input voltage is relatively high, and it cannot work under the easily realized low input voltage condition, and the power consumption is large, so the actual operation is inconvenient and the cost is high. With the development of high-temperature superconducting materials and corresponding technologies, it has become possible to manufacture high-temperature superconducting high-current and low-resistance loss coils. Using high-temp...
