Abstract

The invention relates to a phase isolated cast tubular bus and a preparation method thereof and belongs to the technical field of power transmission and distribution. The tubular bus is characterized in that flat joints are arranged at the two ends of a tubular bus main body; a resin insulating layer is cast outside the tubular bus main body; the section outline of the insulating layer is composed of a circular arc segment concentric with the tubular bus, extending line segments tangent with the two sides of the circular arc segment and a horizontal line segment intersecting with the two extending lines; the length of the horizontal line segment is greater than the diameter of the circular arc segment; and the circular arc segments are arranged above to form gas overflowing surfaces during casting and are arranged below to form positioning surfaces during installation. According to the invention, the convention is broken, thus an ideal casting effect can be achieved and the compact insulating casting layer can be formed, without the assistance of special equipment, thus solving the problem of insulating casting of the tubular bus; and the cast planes formed by opening casting become the ideal positioning surfaces during installation, thus achieving two aims at once.

Description

technical field

[0001] The invention relates to a busbar for power transmission, in particular to a phase-isolated cast tube busbar, and also relates to a preparation method thereof, which belongs to the technical field of power transmission and distribution. Background technique

[0002] Busway is an important component of power transmission and distribution, and its insulation performance directly affects the quality of power transmission. In order to overcome the disadvantage that the insulating layer achieved by the traditional winding and coating process is difficult to ensure a compact structure, the Chinese patent document with the publication number CN 2605687Y discloses a bus bar with a casting structure, in which each bus bar conductor is wrapped by a cast resin insulator, and each other The intervals are separated, and multiple bus conductors are solidified into a whole by resin insulators. The insulator is integrally cast together with the busbar conductor, and ...
