Abstract

The utility model relates to a lead and T-shaped connecting plate structure for transformers and belongs to the technical field of transformers. The technical scheme includes that the lead and T-shaped connecting plate structure comprises three leads (1), three press joints (2) and a T-shaped connecting plate (3), the three press joints are arranged at ends of the three leads, three ends of the T-shaped connecting plate are provided with bolt holes, and the three press joints are respectively connected with the T-shaped connecting plate through bolts. Edges of the T-shaped connecting plate are chamfered, electrode shape can be improved, and local electric field intensity is reduced. The size and thickness of a wiring board can be customized according to size and current of the press joints, and needs of current density are met. The surface of the wiring board is subjected to finish machining, conductivity of the contact surface of the wiring board contacting with the press joints is improved, and application performance is also improved. The lead and T-shaped connecting plate structure has the advantages that connection mode of three T-shaped lines can be optimized, and the problems of difficult connection of the lines, short insulation distance and high lead stress are solved.

Description

A kind of transformer lead T shape connecting board structure
Technical field
The utility model relates to a kind of transformer lead T shape connecting board structure, belongs to the transformer technology field.
Background technology
At present, there is the situation of the connection on a large amount of T shape three-route roads in transformer inside.During connection, need and wherein one the tunnel to turn on the parallel circuit of other two-way, could use pressure joint to couple together three the tunnel.Along with the continuous development of high-power transformer, the heavy in section lead-in wire is widely used, and requiring of its turn round stress and radius is increasing, has caused the situation that connection is difficult, insulation distance reduces, wire stress strengthens.
The utility model content
The utility model purpose is to provide a kind of transformer lead T shape connecting board structure, and the method for attachment on T shape three-route road is optimized, and solves the problems referred to above that background technology exists.
The technical solution of the utility model is: a kind of transformer lead T shape connecting board structure, comprise lead-in wire, pressure joint, T shape connecting plate, the end of three lead-in wires arranges respectively pressure joint, three ends on T shape connecting plate arrange respectively bolt hole, and three pressure joints connect respectively T shape connecting plate by bolt.
The T shape connecting plate that described T shape connecting plate is made by copper coin, T shape connecting plate arris chamfering, Surface Finishing is processed.The size of T shape connecting plate and thickness customize according to pressure joint size and size of current, to satisfy the needs of current density.
The edge chamfering of T shape connecting plate can improve electrode shape, reduces local electric field strength; The size of terminal block and thickness customize according to pressure joint size and size of current, satisfy the needs of current density; Process through fine finishining on the terminal block surface, and the conductive capability of raising and pressure joint contact-making surface improves its effective utilization.
The beneficial effects of the utility model: the method for attachment on T shape three-route road is optimized, has improved connection difficulty, insulation distance reduces, wire stress strengthens situation.
