Problems solved by technology

[0003] The plate sections connected by bolts in existing high-voltage and high-current terminals are generally single-sided plate-shaped, with limited contact area, and because the contact surface is a pure plate without a 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 comb-type high voltage and large current connecting terminal, wherein one end of the connecting terminal is connected with an aluminum twisted wire and theother end is connected with a lead-out bushing of a transformer; the connecting terminal comprises a first connecting terminal and a second connecting terminal; the first ends of the first connectingterminal and the second connecting terminal are hollow cylindrical sections and the second ends are panel sections with mounting holes; the panel section of the first connecting terminal is fixedly connected with the panel section of the second connecting terminal through a bolt; and the comb-type high voltage and large current connecting terminal is characterized in that at least one contact surface of the panel section of the first connecting terminal and the panel section of the second connecting terminal is provided with comb-type grooves and comb-type bulges coming in pairs. Through implementation of the comb-type high voltage and large current connecting terminal, displacement between the terminals can be avoided, and meanwhile, the contact area of the connecting terminals is improved.

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 comb-tooth-type 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 flat section with mounting holes, which is connected by bolts for easy installation and disassembly. [0003] The plate sections connected by bolts in the existing high-voltage and high-current terminals are generally single-sided plate-shaped, with limited contact area, and because the contact surface is a pure plate, there is no tight mechanical limit structu...
