A New Type of High Voltage Overhead Dense Bus Arrangement System

Abstract

The invention discloses a novel high-voltage overhead intensive type busbar distribution system which comprises a stand column, a support, a hoop, an A-phase capacitance type isolated bus, a B-phase capacitance type isolated bus and a C-phase capacitance type isolated bus, wherein the support is arranged above the stand column, and the A-phase capacitance type isolated bus, the B-phase capacitance type isolated bus and the C-phase capacitance type isolated bus are respectively composed of a plurality of U-shaped capacitance type isolated buses. Each U-shaped capacitance type isolated bus comprises a straight middle part and two arm parts, wherein two ends are respectively bent towards the same side to form the two arm parts, two arm parts of each U-shaped capacitance type isolated bus of each capacitance type isolated bus are placed downwards to be correspondingly connected with the same-phase wire outlet position of lower equipment, and the hoop enables the straight middle part to be fixed on the support. Compare with the prior art, the capacitance type buses replace bare aluminum tubes, insulators are omitted, three phases of buses can distributed intensively, the widths of bus channels are greatly reduced, and the problem that falling articles are in lamp joint with the two buses to cause short-circuit accidents is resolved.

Description

technical field [0001] The invention relates to the field of high-voltage electrical appliances, in particular to an overhead arrangement system for transmitting high voltage. Background technique [0002] At present, the overhead main busbars between high-voltage substations are connected and arranged by using insulators to support bare aluminum tubes. [0003] However, the corridor of the three-phase busbar in the above-mentioned connection method is relatively wide. In addition, if a typhoon strikes, objects such as long objects fall on the two-phase busbar, which will cause a short-circuit accident. Contents of the invention [0004] The present invention provides a new type of high-voltage high voltage that replaces bare aluminum tubes with capacitive insulated busbars, saves insulators, can arrange three-phase busbars densely, greatly reduces the width of busbar corridors, and can avoid short-circuit accidents caused by falling objects overlapping two busbars Overhe...
