Eight development direction of China's medium voltage variable frequency drive

2016-08-30 09:52:35 Bobo HUAFEI Group

REVIEW: medium voltage variable frequency drive is generally used in low-power high-voltage motors make use frequency energy, low - high way high-voltage inverter is used to control low-voltage inverter, the direct use of step-up transformer using the voltage to the motor voltage. The following Huafei GBP series pressure transducer application case, the direction of the eight development pressure transducer had a very comprehensive presentation, application industry including petrochemical, mining and electricity.

OFweek Industrial News: medium voltage variable frequency drive is generally used in low-power high-voltage motors make use frequency energy, low - high way high-voltage inverter is used to control low-voltage inverter, the direct use of step-up transformer using the voltage to the motor voltage.

Future Medium Voltage Frequency Control Technology will be developed in the following eight areas, mainly as follows:

1. The medium-voltage variable frequency drive will be in the high-power, small size, light direction.

2. The medium voltage inverter will be toward the high-pressure devices and multiple direct superposition (devices in series and series units) in two directions.

3. The higher the voltage, the new power semiconductor devices will be used in higher current high-voltage inverter.

4. Present, IGBT, IGCT, SGCT will continue to play a major role, SCR, GTO inverter will exit the market.

5. Application of speed sensorless vector control, flux control and direct torque control technology will be mature.

6. The full realization of digitization and automation: Parameter-reset technology; self-optimizing process technology; fault diagnosis technology.

7. Apply 32 MCU, DSP and ASIC and other devices, the drive to achieve high-precision, multi-functional.

8. related industries are moving towards specialization, scale development, the social division of labor will become more apparent.

Product: HuaFei GBP series voltage inverter

Petrochemical mining medium voltage inverter power

A petrochemical industry applications: Hua Fei hot standby high voltage inverter in the coking plant Gas Blower

HuaFei GBP third generation high voltage variable frequency drive hot standby system with high accuracy, high speed, can automatically identify the motor rotation direction and so on. Millisecond switching time of the system can greatly enhance system reliability, the switching process is smooth without any electrical and mechanical shock, without any impact on the normal production, truly a two-way switch freely without disturbance, can greatly improve the life of the load, the full ensure continuous stability of production, particularly suitable for use in various industries critical load.

Mining Industry Application Option II: variable frequency drive applications in the 25 km long-distance belt conveyor system Huafei pressure

HuaFei GBP belt series dedicated medium voltage inverter has many advantages, fully meet the long-range multi-motor drive belt various operating conditions, to solve the long-range multi-machine drive torque balance. So far, a total delivery of 1 million tons of coal, freight savings of nearly 15 million yuan, resulting in high economic efficiency, the entire belt running less than two years to completely recover the investment cost.

Application program three power industry: large-scale coal-fired unit boiler feed pump frequency conversion transformation plan

 

HuaFei GBP medium voltage variable frequency drive large-scale coal-fired units in the boiler feed water pump on applications for high-power energy-saving boiler feed water pump frequency put forward new ideas. This program is a drag of a typical program, QS1, QS2 the isolation switch.
