High Voltage Separate Transformer

Abstract

The invention relates to a separating transformer, in particular to a high-voltage separating transformer for high and low voltage coil separation, and belongs to the technical field of transformers. The high-voltage separating transformer comprises a mounting bottom plate. A low-voltage coil wraps the upper portion of an iron core; the front side and the rear side of the iron core are respectively provided with two high-voltage insulation struts, the lower ends of the high-voltage insulation struts are connected with the mounting bottom plate through first screws, and the upper ends of the high-voltage insulation struts are connected with a high-voltage coil through second screws; the high-voltage coil is located on an outer circle of the low-voltage coil, and an coil duct is arranged between the high-voltage coil and the low-voltage coil. The high-voltage coil is separated from the low-voltage coil, the withstand voltage requirement of the transformer is met through the coil duct between the high-voltage coil and the low-voltage coil, the creepage direction of the high-voltage coil and the low-voltage coil is changed, namely creepage is achieved through the high-voltage epoxy bottom plate and the high-voltage insulation struts to increase the creepage distance, and insulating materials and the size of the transformer are reduced.

Description

technical field [0001] The invention relates to a separate transformer, in particular to a high-voltage isolation transformer with separate high-voltage and low-voltage wire packages, and belongs to the technical field of transformers. Background technique [0002] At present, due to the needs of technological development, the isolation voltage of the isolation transformer is getting higher and higher, the transformer has to increase the insulation thickness between the high and low voltage wire wraps to meet the withstand voltage requirements, and the creepage distance needs to increase the insulation material to wrap the wire wrap It can be met by winding into a trapezoidal structure, but meeting the corresponding requirements by this method will lead to a large transformer and waste of insulating materials. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a high-voltage separate transformer...
