Abstract

The invention provides a forced air cooling method and device for an isolated-phase enclosed busbar. The forced air cooling method is used for cooling an air cooling busbar with a shell and a tubular conductor and includes the following steps that cold air flows in the same direction as an interlayer between the shell and the conductor along the interior of the conductor of the air cooling busbar. The forced air cooling device comprises a circulation fan, an air cooler and the air cooling busbar used for cooling the shell and the tubular conductor and further comprises an input channel and the interlayer, wherein the input channel is used for being connected between an air outlet of the circulation fan and the first end of the air cooling busbar, and the interlayer is used for conveying the cold air output by the circulation fan into the conductor of the air cooling busbar and into the portion between the shell and the conductor. According to the air cooling method and device, the inner surface and the outer surface of the busbar conductor can make direct contact with air flow, equipment layout is simple, the cooling effect is more excellent, the heat exchange efficiency is high, the problem of insulation of an air inlet and the air outlet is solved, and the problem of isolation of the interlayer and an inner tube of the conductor in a double-air system does not need to be considered too much.

Description

technical field [0001] The present invention relates to the technical field of forced air-cooled isolated-phase closed busbar (other parts or simply called air-cooled busbar), in particular to a forced-air-cooled method and device for separated-phase enclosed busbar. Background technique [0002] The isolated-phase closed busbar is a large current transmission device widely used in the lead-out circuit of 50MW and above generators and the branch circuit of the plant. Such as figure 1 As shown, the A-phase 21, B-phase 22, and C-phase 23 of the isolated-phase closed bus are mainly used between the outlet of the generator 13 located in the indoor 11 and the main transformer 14 located in the outdoor 12, and are used to transmit the power generated by the generator 13. electrical energy. Such as Figure 2-Figure 5 As shown, the phase-isolated closed busbar is mainly composed of conductors 311 / 321 / 331, housings 31 / 32 / 33 or conductors 811 / 821 / 831, housings 81 / 82 / 83 and insulati...
