A busbar support device and a busbar transmission system using the support device

Abstract

The invention relates to a busbar support device and a busbar transmission system using the support device, The busbar support device comprises at least two support layers arranged in order from top to bottom to respectively support the respective busbars, and each support layer is provided with a support structure for supporting the respective busbars, and the support structure has a sliding support surface for supporting the busbars and sliding fit with the busbars for sliding adjustment of the busbars. When the temperature of the busbar changes and thermal expansion and contraction occur orwhen vibration occurs, As that bus bar can be slip on the sliding support surface, the problem that the bus bar can not be released when the bus bar is thermally expand and cold contracted due to thewelding leg outside the bus bar housing in the prior art is avoided, and the support device can simultaneously support the bus bars arranged in more than two layers, so that the support device is flexible in installation and convenient in use.

Description

technical field [0001] The invention relates to the field of busbar transmission equipment, in particular to a busbar support device and a busbar power transmission system using the support device. Background technique [0002] GIS (Gas Insulated Metal Enclosed Switchgear) is an important part of power transmission in power plants and substations, and its safe and reliable operation is the basic condition for successful power transmission in power plants and substations. The bus bar for GIS includes the bus bar shell and the bus bar conductors arranged in the bus bar shell. In order to reduce the footprint of GIS, the GIS bus bar is mostly arranged in upper and lower layers. In GIS engineering, when the length of the bus bar is long, the middle The GIS busbar needs to be supported.

The bus bar for GIS includes the bus bar shell and the bus bar conductors arranged in the bus bar shell. In order to reduce the footprint of GIS, the GIS bus bar is mostly arranged in upper and lower layers. In GIS engineering, when the length of the bus bar is long, the middle The GIS busbar needs to be supported. The existing technology is to weld the outriggers at the corresponding positions of the busbar shell, and support the busbar through the outriggers, which leads to a complex structure of the busbar shell and increases the production cost.

Moreover, the position of the busbar is fixed through the fixed connection between the outrigger and the ground. The busbar has the problem of thermal expansion and contraction under the constant temperature changes throughout the year. The force of thermal expansion and contraction may cause the busbar to bend and deform, resulting in disturbance In severe cases, it will cause the leakage of insulating gas inside the busbar housing, resulting in unreliable operation of power plants and substations, resulting in serious consequences
