Output terminal and current transformer

Abstract

The embodiment of the present invention provides an output terminal and a current transformer. The output terminal includes a backplane, a magnetic ring, and a plurality of binding posts, wherein theplurality of binding posts pass through the backplane and are fixedly connected to the backplane; the plurality of binding posts are insulated from each other; the first end of each binding post is located on the first side of the backplane; the second end of each binding post is located on the second side of the backplane; the magnetic ring is fixedly connected to the backplane to surround the plurality of binding posts; and the magnetic ring protruding from the second side of the backplane has a smaller size than the second end of each binding post protruding from the second side of the backplane. In the embodiment of the invention, the binding posts and the magnetic ring are integrated into the backplane, and the output terminal can be waterproof and dustproof without a cable gland. Wiring points can be checked without disassembling a current transformer box, which facilitates the installation and maintenance of the output terminal, eliminates the need for separately installing themagnetic ring, and reduces the need for installation space.

Description

technical field [0001] The invention relates to the field of power electronic equipment, and more specifically, to an output terminal and a converter. Background technique [0002] As a power conversion device, the converter has been widely used in power electronic equipment. The final output of the converter is alternating current or direct current, and currently the converter usually uses a transfer copper bar or directly uses a cable crimped with a connecting terminal (such as an OT terminal) to output electric power. [0003] When two or more outputs are required, the converter outputs electric energy by opening holes in the transfer copper bar or directly setting multiple openings on the busbar body, and using multiple cables. In this two-way or multi-way output structure, the busbar body or the transfer copper bar is fixed on the box body or other structural parts through insulating parts, and the cables are directly tied with cable ties inside the box body.

Problems solved by technology

[0007] The embodiments of the present invention aim at the fact that when the cable output is directly used in the above-mentioned converter, the busbar body bears a large stress, which is likely to cause uneven current distribution, and the inspection efficiency is low when the transfer copper bar is combined with the cable output, To solve the problem of cumbersome operation, an output terminal and converter are provided
