Novel current transformer wiring terminal

Abstract

The invention discloses a novel current transformer wiring terminal. The novel current transformer wiring terminal comprises a current transformer (1) and is characterized in that a wiring end face of the current transformer (1) is provided with three columns and six rows of 14 pressure holes (4) with screws; the pressure holes in a column a are five communicated pressure holes including three pressure holes in first to third rows and two pressure holes in the fifth and sixth rows; the pressure holes in a column b include four communicated pressure holes in first to fourth rows; the pressure holes in a column c are five communicated pressure holes including two pressure holes in first and second rows and three pressure holes in fourth to sixth rows; a pressure hole a3 and a pressure hole b3 are connected through a first connection plate (2), and a pressure hole b4 and a pressure hole c4 are connected through a second connection plate (3); the lateral side of the wiring end of the current transformer (1) is provided with three wire insertion holes (5), and the three wire insertion holes (5) are communicated with the three columns of the pressure holes through conductors respectively; the pressure holes in each column are upwardly connected with an external circuit by the aid of wires through the three wire insertion holes (5) respectively and downwardly connected with the current transformer. The novel current transformer wiring terminal has advantages of simple principle, easiness in use, high operation efficiency, wide application range and high safety factor.

Description

[0001] Technical field: [0002] The invention relates to a novel transformer terminal, which is widely used in the field of high-voltage equipment in the electric power industry, and belongs to the technical field of electric power measurement. [0003] Background technique: [0004] The current transformer (Current Transformer, referred to as CT), its principle is based on the principle of electromagnetic induction, and consists of a closed iron core and a winding. Its primary winding has very few turns, and it is connected in series in the line of the current to be measured, so it often has all the current of the line flowing, and the secondary winding has a large number of turns, connected in series in the measuring instrument and the protection circuit, and the current mutual inductance When the transformer is working, its secondary circuit is always closed, so the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the wo...
