High-voltage lead connection structure of novel traction transformer

Abstract

The invention discloses a high-voltage lead connection structure of a novel traction transformer. The high-voltage lead connection structure comprises a tee joint, a coil primary wire and a copper pipe; the tee joint comprises an upper joint, a left joint and a right joint; the upper joint is provided with a crimping head; the coil primary wire passes through the crimping head to enter the tee joint; the outer side of the coil primary wire is packaged with crepe paper; semi-conductive crepe paper is arranged on the outer side of the crepe paper; external packaging crepe paper is arranged on the outer side of the semi-conductive crepe paper; the two ends of the left joint and the right joint are connected with the copper pipe separately; and the external packaging crepe paper is arranged onthe outer side of the copper pipe. The high-voltage lead connection structure is simple in structure, high in practicability, high in safety and capable of promoting popularization.

Description

technical field [0001] The invention relates to the technical field of transformer production, in particular to a novel traction transformer high-voltage lead wire connection structure. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. [0003] The assembly of transformer lead wires is one of the key processes in transformer production, and its processing quality directly affects the overall quality and operational reliability of the transformer. Traditional transformer lead wire supports are generally rooted on the upper and lower clamps of the iron core, and the structure is complicated and cumbersome.

[0003] The assembly of transformer lead wires is one of the key processes in transformer production, and its processing quality directly affects the overall quality and operational reliability of the transformer. Traditional transformer lead wire supports are generally rooted on the upper and lower clamps of the iron core, and the structure is complicated and cumbersome. Fixed rules, there is a certain degree of randomness, and according to the traditional structure, the high-voltage lead wire adopts a copper tube structure. When the wire enters from the middle of the copper tube, the coil original wire is wrapped around the copper tube and welded firmly, while when the wire is fed from the end of the copper tube, It is connected by bolts, the connection is not stable enough, and the electrode shape of this part is not good, which cannot meet the requirements for partial discharge of the product
