Abstract

The invention discloses a transformer terminal for connecting an outgoing wire of a coil in a transformer, and the end of the terminal connected with the outgoing wire of the coil is provided with a concave groove, the diameter of the concave groove is larger than the diameter of the outgoing wire of the coil. The transformer terminal can effectively increase the welding contact area. The invention also discloses a high voltage coil gear connection structure and a transformer containing the transformer terminal.

Description

technical field [0001] The present invention relates to the technical field of transformers, in particular to a transformer terminal, and also relates to a high-voltage coil gear connection structure including the above-mentioned transformer terminal and a transformer including the above-mentioned transformer terminal. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. With the rapid development of China's electric power construction, the demand and quality requirements for transformers are increasing day by day. Among them, dry-type transformers are widely used in local lighting and electronic circuits. In the prior art, most of the dry-type transformers use epoxy resin casting type dry-type transformers, and the gear connection of the high-voltage coil is generally welded from the lead coil of the high-voltage coil to the copper terminal on the panel of the cast body. , and then pour the high...
