Abstract
The utility model relates to a separate transformer, in particular to a high-voltage isolating transformer in which a high-voltage solenoid and a low-voltage solenoid are separated, belonging to the technical field of transformers. The high-voltage isolating transformer comprises an installing bottom plate; the upper portion of an iron core is coated with the low-voltage solenoid; the front side and the back side of the iron core are provided with two high-voltage insulating pillars respectively; the lower end of each high-voltage insulating pillar is connected to the installing bottom plate through a first screw; the upper end of each high-voltage insulating pillar is connected with the high-voltage solenoid through a second screw. The high-voltage solenoid is positioned on the outer ring of the low-voltage solenoid, and an oil duct is formed between the high-voltage solenoid and the low-voltage solenoid. According to the high-voltage isolating transformer, the high-voltage solenoid and the low-voltage solenoid are separated from each other, thereby meeting the voltage withstanding requirement through the oil duct between the high-voltage solenoid and the low-voltage solenoid. Moreover, the creepage directions of the high-voltage solenoid and the low-voltage solenoid is changed, namely, the creepage distance is increased through the creepage of a high-voltage epoxy bottom plate and the high-voltage insulating pillars, thereby reducing the sizes of an insulating material and the transformer.
