Dry-type high-frequency high-voltage reactor structure

Abstract

The structure of the dry-type high-frequency high-voltage reactor of the present invention includes a UF-type magnetic core (2), a square skeleton (3), a coil (4), a fixed support device (6) and a copper bar or copper wire (7) leading out of the coil. The square frame (3) is sleeved on the UF core (2); the coil (4) is composed of two high-voltage coils (41), and the two high-voltage coils (41) are vertical structures, respectively wound Made on a square frame (3); the fixed support device (6) includes an upper epoxy board (61), a lower epoxy board (62), a support board (63) and a pull rod (64), and the UF type magnet The core (2) is located on the lower epoxy plate (62), the high-voltage coil is located on the support plate (63), the lower epoxy plate (62) is fixedly connected to the support plate (63), and the upper The epoxy board (61) and the lower epoxy board (62) are connected and fixed by a tie rod (64). Solve the performance defects of poor waveform quality, large reactive power loss, small transfer capacity, low boost voltage, low efficiency, long-term operation and low reliability that exist 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...
