Our country independent mining frequency conversion power system in China southern railway
Production in China with 50% of the world's coal, but lack with independent intellectual property rights of mine frequency explosion-proof power system.
23, announced CSR zhuzhou electric co. , LTD, tangshan and open electrical equipment group co. , LTD. Jointly developed mining frequency conversion motor integrated device, makes our country become the second after Germany to independent research and development of this kind of high-end equipment system.
According to the world energy statistics yearbook 2012 this year, our country will be 19.
Coal output of 5. 6 billion tons of oil equivalent ranks the world's first coal producer.
CSR zhuzhou electric co. , LTD. Technical personnel introduces, large mine winch, boring machine, blowing machine and belt conveyor equipment, such as the most advanced power supply is in bad condition, the safety and stability, high efficiency and energy saving operation of mine frequency explosion-proof motor integrated device.
In the past, the world is only a German companies have research and development ability of this kind of high-end equipment system as a whole.
In recent years, CSR zhuzhou electric co. , LTD and tangshan open electrical equipment group co. , LTD. Jointly organizing technical personnel to carry out research, developed with independent intellectual property rights of mine frequency explosion-proof motor integrated device.
From the testing and commissioning, homemade device has small volume, high efficiency, overload ability and core competence such as high efficiency and energy saving.
