Problems solved by technology

The three-dimensional wound core dry-type transformer installed in the suspension type is convenient for users to connect, and the high and low voltage lead wires must be led out from opposite sides. However, if the connection method of the lead wires in the traditional plane layout is used, the wiring will be complicated, messy, and take up a lot of space. question
In addition, the low voltage of the three-dimensional wound core is not easy to balance the DC resistance due to structural reasons

Abstract

The invention discloses a lead wire structure of a three-dimensional wound core dry-type transformer with suspension installation, and belongs to the technical field of electric power equipment. The three-dimensional wound core dry-type transformer lead structure for suspension installation is composed of A, B, and C three-phase coils wound on the core column. Each phase coil is composed of a high-voltage coil and a low-voltage coil. The three high-voltage coils The connection terminals (31, 32, 33) and the four connection terminals (41, 42, 43, 44) of the low-voltage coil are respectively arranged on the lead brackets (1) located on both sides of the transformer, and the head of the A-phase high-voltage coil is connected to The connecting terminal (31) and the tail of the C-phase high-voltage coil, the head of the B-phase high-voltage coil are connected to the terminal (32) and the tail of the A-phase high-voltage coil, the head of the C-phase high-voltage coil is connected to the terminal (33) and The tail of the B-phase high-voltage coil; the three terminals (41, 42, 43) of the low-voltage coil are respectively connected to the heads of the three low-voltage coils, and the terminal (44) is connected to the tails of the three low-voltage coils.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and specifically refers to a lead wire structure of a three-dimensional wound core dry-type transformer with delta connection for high voltage and star connection for low voltage. Background technique [0002] At present, the traditional ground-mounted three-phase transformers on the market have high and low voltage leads drawn from opposite sides, which is convenient for users to connect. The three-dimensional wound core dry-type transformer installed in the suspension type is convenient for users to connect, and the high and low voltage lead wires must be led out from opposite sides. However, if the connection method of the lead wires in the traditional plane layout is used, the wiring will be complicated, messy, and take up a lot of space. question. In addition, the low voltage of the three-dimensional wound core is not easy to balance the DC resistance due to structural reasons. ...
