Novel dry type small-size high-voltage rectification transformer structure

Abstract

The invention discloses a novel dry type small-size high voltage rectification transformer structure which comprises a high-voltage package, a low-voltage package coupled with the high-voltage package and a transformer magnet core arranged in the low-voltage package. The high-voltage package comprises at least two high-voltage sub-line packages which are respectively coupled with the low-voltage package. The high-voltage package further comprises at least two rectification circuits respectively connected with the high-voltage sub-line packages. The output ends of the rectification circuits are connected with one another in series. The rectification circuits rectify high-frequency voltage generated by the high-voltage sub-line packages, and then are overlapped in series and output the high-frequency voltage. The novel dry type small-size high voltage rectification transformer structure can improve the insulativity and the safety of transformers and can shrink the size of the transformers, brings convenience to the arrangement by workers, is stable and safe in work, and is especially suitable for requirements of large-power equipment.

Description

technical field [0001] The invention relates to a rectifier transformer, in particular to a novel dry-type small-volume high-voltage rectifier transformer structure with convenient production, good heat dissipation effect and high safety. Background technique [0002] In actual production, the output DC voltage of the rectifier transformer of some large-scale equipment is relatively high, the output power is large, and the temperature of the rectifier module is relatively high. The temperature of the rectifier module is high and it has been running for a long time. The traditional epoxy potting dry-type rectifier high-voltage transformer rectifier plate has a high operating temperature rise, the design of the heat dissipation structure of the rectifier plate is complex, the insulation safety between the wire packages is low, and the safety distance needs to be set larger, which results in a larger transformer volume and production. The process is complicated and the cost is...
