Phase-isolated bus shell supporting device and phase-isolated bus shell hoisting system

Abstract

A phase-isolated bus shell supporting device comprises a supporting beam, a supporting base and a hoop, the supporting base is an insulating supporting base and is arranged on the supporting beam, and the hoop is used for installing a shell of a phase-isolated bus and is fixedly arranged on the supporting beam in an insulating mode through the supporting base. Based on the phase-isolated bus shell supporting device, the invention further provides a phase-isolated bus shell hoisting system. According to the bus shell supporting device, the material of the support base is changed into the insulating material from the steel material, and an insulating block does not need to be mounted when the insulating support base is used, so that the mounting height of the bus can be reduced, and the number of assembly parts of the bus support structure is reduced; and according to the structural design, the structural strength of the phase-isolated bus shell supporting device can be remarkably improved, and the structure of the phase-isolated bus shell supporting device is simplified. In addition, the H-shaped steel with high strength is used as the supporting beam, and the structural strength and the deformation resistance of the supporting beam are improved on the premise that the H-shaped steel is not damaged.

Description

technical field [0001] The present invention relates to the technical field of electric power systems, and more specifically relates to a support device for an isolated-phase busbar enclosure and a hoisting system for an isolated-phase busbar enclosure. Background technique [0002] The off-phase bus has the characteristics of high current, high mechanical strength, good insulation, and wide application range, and has been recognized and praised by customers for a long time. [0003] Please refer to figure 1 and figure 2 ,in, figure 1 It is a structural schematic diagram of a typical out-of-phase busbar housing support structure in the prior art; figure 2 for figure 1 Schematic diagram of the cross-sectional structure along A-A. [0004] In the prior art, the off-phase busbar needs to use the shell support structure to support the busbar shell and fix the busbar position. The shell support structure is composed of shell support beam a, channel steel hoop b, support b...

AI Technical Summary

Problems solved by technology

[0006] 1. The off-phase busbars are usually three-phase busbars arranged side by side. When the busbars are short-circuited, there will be a tendency for relative movement between the busbars of each phase under the action of short-circuit electrodynamic force. At the same time, there is no support between the shells of the busbars of each phase, and the receiving Due to the lack of supporting force during dynamic action, the above-mentioned movement tendency may cause damage to the busbar and supporting structure;

[0007] 2. When the busbar is arranged, the hoisting structure needs to be used in some sections. Due to the height difference between the installation foundations of the buildings and the certain installation error in the layout of the busbar itself, the hoisting structure used for the busbar installation needs to have a certain adjustment function. However, because the traditional hoisting structure does not have the adjustment function, it is difficult to adjust the height of the busbar hoisting operation;

[0008] 3. The supporting base is a steel (conductive) structure. In order to maintain insulation with the supporting beam of the shell, it is necessary to install an insulating block, which not only makes the support structure of the off-phase bus complicated, but also causes the entire supporting base structure to be damaged due to the existence of the insulating block. weakened in strength;

[0009] 4. The supporting beam of the shell is welded by two pieces of channel steel. The supporting beam of the shell is affected by the welding quality, and its strength needs to be improved
