Dry-type high-frequency high-voltage transformer structure

Abstract

The dry-type high-frequency high-voltage transformer structure (1) of the present invention is characterized by comprising an EE-type magnetic core (2), a square skeleton (3), a square coil (4) and afixed support device (6) and further comprising a lead-out copper bar or copper wire (7) of the coil, wherein the EE magnetic core (2) is formed by installing two E-type magnetic cores (21) in such away that the openings of the two E-type magnetic cores are opposite to each other and the two E-type magnetic cores are aligned in the vertical direction; the square skeleton (3) sleeves the central pillar of the EE-type magnetic core (2); the square coil (4) is a vertical structure and is formed by winding a combination of a low-voltage coil (41) and a high-voltage coil (42) around the square skeleton (3); and the high-voltage coil ( 42) and the low-voltage coils are alternately wound around the square skeleton (3). The dry-type high-frequency high-voltage transformer structure solves the performance defects of low transmission capacity, low step-up voltage, low efficiency, incapability of long-term operation and low reliability in the current high-frequency and high-voltage fields such that a high-frequency and high-voltage power supply can be used widely and reliably.

Description

[0001] Original invention name: a large-capacity dry-type high-frequency high-voltage transformer [0002] Original application number: 201610285249.0 [0003] Original application date: 2016-05-04 Technical field: [0004] The invention belongs to the field of dry-type transformers and is classified into high-voltage electrical equipment, and specifically relates to a large-capacity dry-type high-frequency high-voltage transformer. Background technique: [0005] Existing conventional transformers more or less have the following technical shortcomings, which cause the existing high-frequency and high-voltage transformers to have small transfer capacity (below 10kVA), low boost voltage (below 1000V), low efficiency (below 90%), and cannot be long-term Insufficient technology with low operation and reliability. [0006] 1. The winding methods of conventional transformers are relatively uniform. Basically, the low-voltage coil is wound first, and then the high-voltage coil is wound outsi...
