Product Description
Mining Frequency Converter Voltage Converter 660V/1140V
Product Description
1.Interference on the power grid and other equipment is small.
2. The motor insulation damage mature governance programs.
3. Has excellent power balance function, multi-motor drive system to ensure each motor output balance, unbalance less than 3%.
4. Has excellent closed loop (PID) control capabilities to meet the requirements of pumps.
Rated voltage | AC660V/1140V |
Rated power | 37-500kW37-500kW/132-1000KW |
Overload coefficient | 1.2Ie two minutes, 1.5Ie one minute(According to customer requirements, can increase the overload factor) |
Heavy starting | having heavy starting capability |
Multi machine power balancing function | The current difference between the frequency converter is less than 3% |
Protection function | With over current, over voltage, under voltage, short circuit, overload, lack of phase, motor overheating, system overheating, and instantaneous power protection
|
Display function | Frequency changer show has the motor current, voltage, frequency, speed, temperature, power electric parameters, such as display function; With Running state and fault, alarm display function; With the function of fault record and can record the fault information . |
The products are divided 660V, 1140V two series, mainly used in coal mine with a coal dust, methane and other explosive atmospheres, drag motor speed running, heavy duty motor soft starting to realize soft stop, stepless speed regulation and other functions, has a small starting current, output torque, speed, smooth, small impact to power grid, the advantages of easy to control.
1. Take full accountof the coal mine requiressimple maintenance needs, the mine explosion-proof inverter has the following characteristics:
Main internal components of the modular design of the split between the modules to facilitate the demolition, easy maintenance;
Optional doorOpen the door structure, easy maintenance workload saving, saving maintenance time.
2. Disturb slightly to the electrical network and other equipment
Set up a dedicated front-end converter input filter, to ensure that the drive to the front forpower distribution equipment to minimizeinterference to meet the national standard.
3. Motorinsulationdamagematuregovernance program:
Two level frequency changer out-port may choose our company specialized design the output filter, but suppresses the frequency changer output wave shape effectively to the long electric cable power supply electrical machinery insulation damage, may lengthen the 1140V frequency changer to the electrical machinery electric cable distance to 60 meters above, may lengthen the 660V frequency changer to the electrical machinery electric cable distance to 100 meters above.
May choose the 1140V three level frequency changers, causes the frequency changer output wave shape for to reduce greatly to the electrical machinery insulation damage, effective addressing electrical machinery insulation damage difficult problem;
4. Has excellent power balance function, multi-motor drive system to ensure each motor output balance, the imbalance of less than 3%.
5. Excellent closed loop (PID) control capabilities to meet the requirements of pumps.
6. With perfect and complete data communications function, easy mine information construction.
7. various types of application solutions complete and perfect.
8. The company has spent a lot to build load test platform, can effectively ensure product reliability.
