Abstract

The invention discloses a dry-type high-frequency high-voltage reactor structure, and the structure comprises a UF-type magnetic core (2), a square framework (3), a coil (4), a fixed supporting device(6) and a coil lead-out copper bar or copper wire (7), wherein the square framework (3) is arranged on the UF-type magnetic core (2) in a sleeving manner; the coil (4) is composed of two high-voltagecoils (41), and the two high-voltage coils (41) are of a vertical structure and are respectively wound on the square framework (3); the fixed supporting device (6) comprises an upper epoxy plate (61), a lower epoxy plate (62), a supporting plate (63) and a pull rod (64); the UF-type magnetic core (2) is located on the lower epoxy plate (62); the high-voltage coils are located on the supporting plate (63); the lower epoxy plate (62) is fixedly connected with the supporting plate (63), and the upper epoxy plate (61) is fixedly connected with the lower epoxy plate (62) through the pull rod (64).The structure irons out the performance defects of poor waveform quality, large reactive loss, small transmission capacity, low boost voltage, low efficiency, incapability of long-term operation andlow reliability in the current high-frequency and high-voltage field.

Description

[0001] The name of the original invention: a large-capacity dry-type high-frequency high-voltage reactor [0002] Original application number: 201610284931.8 [0003] Original application date: 2016-05-04 Technical field: [0004] The invention belongs to the field of dry-type reactors and belongs to high-voltage electrical equipment, in particular to a large-capacity dry-type high-frequency high-voltage reactor. Background technique: [0005] In the field of step-up or conversion of existing medium and high-frequency power supplies, conventional reactors more or less have the following technical shortcomings, resulting in the existing high-frequency high-voltage reactors having small boost capacity (below 10kVA) and low boost voltage ( 1000V), poor waveform quality, large reactive power loss, low efficiency (below 90%), incapable of high-capacity long-term operation and low reliability. [0006] 1. Since the coil is in a vertical state when the reactor is assembled, the e...
