10-kilovolt full-poured medium-voltage bus

Abstract

The invention provides a 10-kilovolt full-poured medium-voltage bus which comprises a three-phase conductor and an insulator. The three-phase conductor is arranged in the insulator appropriately in parallel, the insulator is formed through full pouring, a plurality of rectangular radiating holes are formed between phases of the three-phase conductor, the length of each rectangular radiating hole is 440 millimeters, the width of each rectangular radiating hole is 80 millimeters, semicircle radiating holes are formed in the two ends of the three-phase conductor, and the diameter of each semicircle radiating hole is 80 millimeters. The 10-kilovolt full-poured medium-voltage bus is simple in structure. The distance between the rectangular radiating holes is increased to 120mm, so that the radiating volume is improved, and thermal stability and dynamic stability endurance are improved. Meanwhile, the radiating volume is improved by more than 200%, so that the copper using amount is reduced and energy conversation is achieved. In addition, the whole pouring amount is reduced, the whole weight of an assembly is relatively reduced, and time and labor are saved in construction and supporting of a hanging bracket.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a 10-kilovolt fully cast medium-voltage busbar. Background technique [0002] At present, there is no heat dissipation device between the three-phase conductors of the 6~kv fully cast bus bar (that is, the three-phase conductors are cast in a large rectangular castable material), so when the current is small (such as 800A~1000A), due to the heat generation Small, it is still reasonable, but when it exceeds this capacity, the heat dissipation effect is greatly reduced due to the large current relative to the heat generation. The copper usage becomes very inefficient relative to the output current, which has a great impact on resource utilization. waste. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is: to provide a 10kV fully cast medium voltage busbar, which has a simple structure, the heat dis...

[0002]At present, there is no heat dissipation device between the three-phase conductors of the 6~kv fully cast bus bar (that is, the three-phase conductors are cast in a large rectangular castable material), so When the current is small (such as 800A~1000A), it is still reasonable because the heat generation is small, but when it exceeds this capacity, the heat dissipation effect is greatly reduced due to the high current relative to the heat generation. The amount of copper used is relative to the output The output current becomes very inefficient, resulting in a great waste of resource utilization
