Name: 12T narrow gauge frequency change mine locomotive
Model No.: CJY12/6GP
Trolley locomotive:
Locomotive using DC electrical line, DC transformed to three phase AC by computer traction transformer, the voltage and frequency can be adjusted, which can drive two AC asynchronous motor, by reduction gear driving axle to tract locomotive.The core parts of traction transformer using 32 digital DSP chip, fast speed with quick response.Have good sticking and big traction.Reliable AC electrical motor, with wide range of speed regulation.Less cost for maintenance, can avoid ring fire and burnt compared to DC driving.The products are suitable for transportation traction on the narrow rail for the field of coal, metallurgical industry, mining, forest, railway, road tunnel construction and etc.Locomotive can be used elevation within 2000m, metal mine or non-hazardous area.Technology Advantages
1. The vector control transformer, AC frequency change electric motor and new locomotive cabinet designed and developed by ourself.
2. The products has good sticking, good overload ability, good climbing, safety braking, big traction and easy to operate.
3. Human oriented design, the operation table of driver cab has speed/odometer display and locomotive running signal lamp.
4. Energy-saving, 25% energy saved compared to DC driving.
5. The products can adapt mining working environment, accepted temperature within -40°C~+50°C, accepted floated voltage range within -40%~+30%, with dustproof and shakeproof function.
The electric locomotive can be mainly used as a tractive device for trans-mission of mineral, equipment, equipment and personnel in opencast. Besides, it can also be used for railbound transmission on the ground within factories or mines, where the power transmission lines (direct current of 250/550V) will supply the electric locomotive with power. As the electric locomotive isn't equipped with an explosion-proof device, it can't be used in the place where the explosive gases are rather dense.Adopting a tow-step transmission, the electric locomotive has a small size, large trans-mission power. Further more, the life of gears is long. The unique brake system can brake the locomotive proper and train as well. Being bright and broad, the driver's cab may offer you comfortable operation. In addition, the electrical equipment of various kinds can be repaired and maintained very easily.
