Problems solved by technology

[0002] In the power system, busbars with a voltage level below 35kV do not consider stability issues, and generally do not require the installation of special busbar protection. Due to aging and mechanical wear and other reasons, faults within the range of 6/10kV busbars occur from time to time. The operation practice shows that in recent years, the manufacturing technology of high-voltage switchgear has been improved, and the probability of busbar failure has been greatly reduced, which greatly reduces the overall failure caused by switchgear failures. The switchgear on the bus sec

Abstract

The invention discloses a high-performance medium-voltage busbar for nuclear power, which comprises a casing, an installation seat is fixedly installed on the bottom of the inner cavity of the casing, a busbar body is fixedly installed on the top of the installation seat, and a drying box is fixedly installed inside the casing for drying. The inside of the box is fixed with a heating pipe, the air outlet on the top of the drying box is fixed with an exhaust fan, one side of the inner wall of the shell is fixed with a cooling fan, and the other side of the inner wall of the shell is fixed with an aluminum substrate heat conduction sheet. Equidistantly distributed heat pipes are fixedly installed on one side of the heat conduction sheet of the aluminum substrate, and a heat absorption sheet is fixedly installed on one end of the heat conduction pipe. The high-performance medium-voltage busbar for nuclear power generates heat by setting heating tubes, and the heat can be blown away by setting cooling fans, and then the busbar body inside the shell can be dried and dehumidified, so that the dryness inside the shell has been improved. Guarantee, thereby improving the power generation performance of the bus body and reducing the risk of leakage.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a high-performance medium-voltage busbar for nuclear power. Background technique [0002] In the power system, busbars with a voltage level below 35kV do not consider stability issues, and generally do not require the installation of special busbar protection. Due to aging and mechanical wear and other reasons, faults within the range of 6 / 10kV busbars occur from time to time. The operation practice shows that in recent years, the manufacturing technology of high-voltage switchgear has been improved, and the probability of busbar failure has been greatly reduced, which greatly reduces the overall failure caused by switchgear failures. The switchgear on the bus section was severely burned, and it developed into a major accident involving a fire company. [0003] However, the voltage of the nuclear power plant is relatively large, and special busbar protection must be inst...
