A power distribution device with main transformer low frame crossing

Abstract

The invention discloses a power distribution apparatus with main transformer low-framework traverse. The existing power distribution apparatus is large in longitudinal dimensions and large in occupied area; and in addition, by adopting a conventional framework, the framework is relatively high in height. The invention adopts a technical scheme as follows: three phases of an II section bus are upwardly led to an upper overline; then an A phase and a B phase are led out from the upper overline through flexible wires to a suspension pipe bus, and a C phase is led to a supporting column insulator; three phases of an I section bus are downwardly led to HGIS equipment; after passing through the HGIS equipment, an A phase and a B phase are led to the suspension pipe bus, and a C phase is led to the supporting column insulator; the A phases and B phases of the II section bus and the I section bus pass through suspension pipe traverse and then are led downwardly to a lightning arrester, and then are led upwardly from the lightning arrester to a main transformer overline; and the C phases of the II section bus and the I section bus are both led to the lightning arrester, and then are led upwardly from the lightning arrester to the main transformer overline. By virtue of framework optimization, the power distribution apparatus is small in longitudinal dimensions and low in height.

Description

Technical field [0001] The invention relates to the field of power distribution devices, in particular to a power distribution device with a low main transformer frame traversing. Background technique [0002] In the existing power distribution device, the busbar is led to the main transformer through the upper jumper and the conventional frame. Because the main transformer has a long span, a transition frame needs to be provided, so that the overall longitudinal size of the power distribution device is large and the area is large. ; In addition, due to the conventional structure, the height of the structure is relatively high. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art, and provide a power distribution device that does not require a transitional frame for the main transformer low frame to traverse, so as to reduce the longitudinal size of the power distribution device an...

[0002] In an existing power distribution device, the busbar is led to the main transformer through the upper jumper and the conventional frame. Since the main transformer has a long jumper, a transition frame needs to be installed, so that the overall longitudinal size of the power distribution device is large and the floor area is large. ; In addition, due to the conventional structure, the height of the structure is relatively high
