Anti-rollover oriented busbar sliding support structure and busbar power transmission system

Abstract

The invention relates to a rollover prevention guide type bus sliding support structure and a bus power transmission system, so as to solve the problem that the bus support structure in the prior artmay cause rollover and overturning of buses. The support structure comprises a lower bracket fixed on a base bracket and an upper bracket fixing the bus, wherein the upper and lower brackets are respectively provided with a sliding guide seat and a fixed guide seat which are arranged at intervals in the horizontal direction, the fixed guide seat and the sliding guide seat are respectively provideda non-horizontal fixed guide surface and a sliding guide surface extending along the axial direction parallel to the bus with a sliding guide fit so that the upper and lower brackets slide relative to each other only in the axial direction of the bus, and a hooking structure for blocking the axial rotation of the upper bracket relative to the lower bracket around the bus is provided between the upper and lower brackets. Since the upper and lower brackets can only slide relative to each other along the axial direction of the bus to adapt to the thermal expansion and contraction displacement ofthe bus in the axial direction, when the bus is subjected to non-axial external force, the hooking structure connects the upper and lower brackets together to avoid rollover and overturning of the bus.

Description

technical field [0001] The invention relates to an anti-rollover guiding bus bar sliding support structure and a bus bar power transmission system. Background technique [0002] In recent years, with the rapid development of the national power industry, the demand for GIS / HGIS equipment is increasing day by day, especially the number of UHV and DC converter substation projects has also increased significantly. These GIS / HGIS projects generally have the following characteristics: first, the scale of GIS / HGIS equipment is large; second, the main busbar and branch busbar are longer; Big wait. The existing busbar is a round tube busbar, including the busbar shell and the internal busbar conductor, which has a large dead weight. How to solve the problem of supporting the busbar, especially when the ambient temperature changes greatly, is related to the static state of the equipment structure. Stability, shock resistance, and even the stability of the power transmission system, ...
