Main helium fan for high temperature gas cooled reactor

Main helium fan for high temperature gas cooled reactor

Power: 4500kW

Frequency range: 13Hz - 71hz

Maximum speed: 4200r/min

Rated voltage: 6000V

Bearing type: electromagnetic bearing

Technical features: the main helium fan is the only key active equipment in the primary circuit of the nuclear reactor of the demonstration project of high temperature gas cooled reactor nuclear power plant, one of the 16 major projects in the outline of the national medium and long term scientific and technological development plan in the eleventh five year plan. Its function is to drive the coolant in the primary circuit - 7.0 MPa helium, flow through the reactor core, and when the reactor is under normal startup, power operation and shutdown conditions, provide enough flow of helium to take away the heat generated by the reactor core through the primary circuit system; This product is the first high-power main helium fan supported by electromagnetic bearing in the world. There is no product with equivalent capacity and similar structure in the world. A number of technologies fill the domestic gap, are the first in China and are at the leading level in the world.

Application: the fourth generation nuclear technology - high temperature gas cooled reactor
