Problems solved by technology

[0003] Existing high-voltage and high-current terminal blocks connected by bolts are generally single-sided plate-shaped, with a limited contact area, and because the contact surface is a pure plate, there is no tight mechanical limit structure, displacement between plates is easy to occur, and the connecting bolts are loose. Cause poor contact, heat and other problems, resulting in electrical equipment must be powered off for maintenance

Abstract

The embodiment of the invention discloses a U-shaped high-voltage large-current wiring terminal. One end of the wiring terminal is connected with an aluminium twisted wire, and the other end of the wiring terminal is connected with a transformer outgoing wire casing pipe. The wiring terminal comprises a first wiring terminal and a second wiring terminal, wherein the first ends of the first and second wiring terminals are hollow cylindrical segments, and the second ends of the first and second wiring terminals are plate-shaped segments with installation holes. The plate-shaped segment of the first wiring terminal and the plate-shaped segment of the second wiring terminal are fixedly connected through a bolt. The wiring terminal is characterized in that the end part of the plate-shaped segment of the first wiring terminal and the end part of the plate-shaped segment of the second wiring terminal form a U-shaped bent plate. According to the embodiment of the invention, the wiring terminalcan avoid the displacement between the terminals, and increases the contact area of the wiring terminals.

Description

technical field [0001] The invention relates to a high-voltage and high-current terminal used in a power supply network, in particular to a U-shaped high-voltage and high-current terminal. Background technique [0002] The high-voltage and high-current terminal is a metal part used to connect large-scale electric equipment. Its function is to conduct current. One end is a hollow cylindrical section. It is processed into a regular hexagon by hydraulic extrusion during installation. It is used for the same cylindrical shape. High-voltage wires, bushing terminals, etc. are permanently connected; the other end is a plate-type section with mounting holes, which is connected by bolts for easy installation and disassembly. [0003] Existing high-voltage and high-current terminal blocks connected by bolts are generally single-sided plate-shaped, with a limited contact area, and because the contact surface is a pure plate, there is no tight mechanical limit structure, displacement be...
