Pipe bus connection method

Abstract

The invention relates to a pipe bus connection method. The pipe bus connection method comprises the following steps of: carrying out prefabricating, sleeved connection, pressed connection and welding on pipe buses and an inner casing pipe, and removing an outer sleeve cylinder and an inner sleeve cylinder, wherein in a prefabricating step, an inner side wall at the sleeve end of each pipe bus and an outer side wall at the connection end of the inner casing pipe are arranged as manually matched conical faces; and the pipe buses are tightly and firmly sleeved with the inner casing pipe by using the outer sleeve cylinder and the inner sleeve cylinder through threaded compression. By utilizing the connection method, the connection between the pipe buses and the connection between the pipe buses and other equipment are convenient and rapid; and the connection between the pipe buses and the connection between the pipe buses and other equipment are tight, firm and compact, and has the advantages of large anti-tension strength, uniform face combination and optimal conductive property. The pipe bus connection method provided by the invention can be widely applied to the technical field of power transmission.

Description

technical field [0001] The invention relates to the technical field of electric power transmission and transformation, in particular to a method for connecting pipe busbars. Background technique [0002] There are two main types of existing technologies for pipe bus connection, one is the external compression type, that is, there are 4 slits at the connection end of the pipe bus, and the inner sleeve is directly embedded in the pipe bus connection, and then connected to the pipe bus. Use a hoop to tighten the outer circle of the end and lock the bolts. This method has the limitations of uneven appearance, unsightly appearance, troublesome follow-up construction, large material consumption, and high cost; the other type is based on the above connection method. After welding the gap at the connecting end of the pipe busbar to make it tightly connected with the inner casing, the hoop is removed. This method overcomes the defects of flat appearance, unsightly appearance, high ma...

AI Technical Summary

Problems solved by technology

The connector has a smooth and elegant appearance, large conductive contact surface, high contact pressure, and high connection reliability, but there are still limitations of insufficient connection and unsatisfactory tensile strength. Tensile, it is bound to increase the end caps at both ends to press tightly to the middle to push the inner tapered sleeve to move to the middle. At this time, it is easy to deform the busbar of the middle pipe and reduce the electrical conductivity
