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 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 rectifier module has a high temperature and has been running for a long time. The traditional epoxy potting dry-type rectifier high-voltage transformer rectifier board has a high operating temperature rise, a complex heat dissipation structure design of the rectifier board, low insulation safety between the wire packages, and a large safety distance, which results in a large transformer volume and production costs. The process is complicated and the cost is high. [0003] Therefore, the existing techn...
