Description

Terminal connecting mechanism of insulating tubular busbar

Technical Field

The utility model relates to an electric power transmission and transformation technical field specifically is a terminal connection mechanism of insulating cast generating line.

Background

The tubular bus is one of key devices in the electric power transmission and transformation system, and plays an important role in safe and reliable operation of the electric power transmission and transformation system and the electric power devices. The existing connecting piece of the insulating tubular bus has the following two connection modes:

one type of connection is by welding. The connection mode can meet the requirements of normal passing rated current and temperature rise in a short time, but has no flexibility, is difficult to beautify in manufacture, and cannot meet the requirements of electrodynamic force generated during building settlement and short circuit, so that hidden danger is brought to the safe operation of a power system.

Another connection mode is that a cylindrical sleeve is sleeved on an insulating tubular bus. The looseness between connecting piece and the generating line appears easily in long-term operation, causes the equipment tip of contact failure to generate heat.

Therefore, how to solve the problems of potential safety hazards and unstable connection when connecting the insulated tubular busbar and the equipment end plate becomes a problem to be solved urgently.

SUMMERY OF THE UTILITY MODEL

In view of the not enough and defect that exists among the prior art, the utility model provides a terminal connection mechanism of insulating tubular busbar always for electric power potential safety hazard and the unstable problem of connection when solving and connecting insulating tubular busbar and equipment end plate.

In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides an insulating tubular busbar's terminal connection mechanism, includes tubular busbar, connector, flexible coupling and equipment binding post, connector one end cross-section is the annular, and other end cross-section is the rectangle, be equipped with the toper recess on the ring of the circular one end of connector, the tip ring of tubular busbar is established to toper spine, toper spine is located in the toper recess, both are corresponding, the periphery of the rectangle one end of connector and the one end fixed connection of flexible coupling, the other end of flexible coupling with equipment binding post connects.

As a further improvement of the utility model, the conical groove is connected with the front end connected with the conical spine through a bolt.

As a further improvement of the utility model, the tubular busbar with the connector junction the connector with the flexible coupling junction the flexible coupling with the outer end of equipment binding post junction is equipped with the insulator and surrounds.

As a further improvement of the utility model, the conical spine part and the contact part of the conical groove are all provided with tin coating.

Compared with the prior art, the utility model discloses the beneficial effect who has does: the utility model discloses a toper recess and toper spine, both are corresponding, and are equipped with the tin coating in its contact department, have realized good electric conductivity, pass through the bolt fastening at its contact department front end, have guaranteed the stability of connecting.
