It is suitable for three-phase AC 50Hz, rated voltage 690V and below, rated current 4000A and below, in three-phase four wire system or three-phase five wire system and other power systems, used for power conversion, distribution and control.
Mining general low-voltage switchgear can be used as a complete set of low-voltage power distribution equipment in the 690V and 400V power supply system of substations in underground coal mines, underground yards without gas and coal dust explosion hazards, workshops with heavy dust corrosion, and wet places of metallurgy, subway and low buildings.
The system consists of 2 units of high efficient PV inverters,one unit of mid-voltage transformer(step up transformer).AC power,DC power, monitoring communications ,and other mobile devices integrated in a mobile house, thereby enhancing the system security as well as relaiblility ,convenient to transport and installation ,improving system efficiency and power output as well.
It is also known as high voltage dynamic reactive power compensation generating device or static synchronous compensator, which is an equipment providing dynamic reactive power compensation through the self commutation of the power semiconductor bridge converter.
It is suitable for communities, shopping malls, schools, supermarkets, substations, industrial enterprises and other power users, with Ac 50Hz, rated voltage 400V, 690V, rated current 1000 ~ 3150A power distribution system.
