Novel special clip for transformer

Abstract

The invention discloses a novel special clip for a transformer. The clip comprises a transformer connecting end and a conductor connecting end, wherein a conductor mounting hole and first threaded holes communicated with the conductor mounting hole and used for mounting pressing bolts are formed on the conductor connecting end; and the conductor mounting hole is a threaded hole. When the pressing bolts apply force and compress conductors, the threaded pointed parts can puncture oxide layers on the surfaces of the conductors to be embedded into the conductors so as to eliminate the influence on the contact between the clip and the conductors from the oxide layers, then the clip and the conductors can be in close contact and the contact resistance is reduced; disc-shaped pressing plates are arranged on the pressing bolts, so that the conductors and the clip can be connected in a constant-pressure state, and loose contact caused by thermal expansion and contraction of the conductors is effectively eliminated; and jaw structure on the transformer connecting end can ensure favorable close contact between the surface of a second threaded hole and the surface of the transformer terminal, and the contact resistance is reduced; and the conductor connecting end can be connected with power conductors of which the sectional areas range from 35mm<2> to 240mm<2>, so that the clip has strong universality.

Description

technical field [0001] The invention relates to a special line clip for a transformer. Background technique [0002] The transformer is the main equipment in the power system, and the special wire clip for the transformer plays the role of connecting the transformer terminal and the wire, which has a very important function. [0003] At present, the commonly used copper plate stamping or casting transformer clamps have defects such as rough process, low strength, small contact area between the pressure plate and the wire, large contact resistance, poor clamping effect and easy to fall off. Moreover, the transformer clamps in the prior art have poor versatility, and the same transformer clamp cannot adapt to wires of different diameters, resulting in a wide variety of transformer clamps, cumbersome selection, and poor interchangeability. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a special wire clamp for transform...
