Problems solved by technology

[0002] Traditional toroidal transformers are generally fixed by upper and lower pressure plates through a screw passing through the center of the transformer. If the transformer with multiple power and lead wires adopts this structure, it is easy to loosen the transformer after a long working time, resulting in the transformer not working normally.
The toroidal transformer has many lead wires. If this wire is used to lead directly, the wiring will be messy, unsightly, and lead to wiring errors.

Abstract

The invention relates to a transformer, in particular to a high-power multi-lead annular transformer. The transformer comprises a base, wherein a sealed insulating plate is arranged on the surface of the base in a bonding manner; a vertically upward coil fixing column is fixed in the middle of the surface of the sealed insulating plate; coils are arranged on the sealed insulating plate around the coil fixing column; an epoxy insulating plate and a cover plate are sequentially arranged at the tops of the coils from the bottom up; the cover plate is connected with the coil fixing column by a cover plate fixing screw in a fastening manner; epoxy resin is poured between the inner sides of the coils and the coil fixing column; wiring plate fixing columns are arranged on the cover plate; a wiring plate is fixedly connected with the wiring plate fixing columns; a plurality of conductive screws are arranged on the wiring plate; and coil outgoing lines are correspondingly connected with the conductive screws. The transformer is stable in structure and neat in wiring.

Description

Technical field [0001] The invention relates to a transformer, in particular to a high-power multi-group lead ring transformer. Background technique [0002] Traditional toroidal transformers generally use upper and lower pressure plates to be fixed by a screw passing through the center of the transformer, and the lead wire adopts the structure led by this wire. This structure is used in the case of low power and not many leads, but there is no big problem. If a transformer with multiple power and lead wires adopts this structure, it will easily become loose after a long working time, causing the transformer to fail to work normally. If there are many toroidal transformer leads, if this wire is used to lead it directly, it will cause the wiring to be messy, unsightly and cause wiring errors. Summary of the invention [0003] In view of the above-mentioned problems, the present invention provides a high-power multi-lead ring transformer with stable structure and neat wiring. [000...
