CTY5/6,7,9GB battery electric locomotive
battery electric locomotive
1. battery electric locomotive
The battery electric locomotive is powered by the battery and the traction motor provides power. Its purpose is to tow an unpowered rail vehicle running on the track, similar to a locomotive. It is generally used in mine transportation, hauling tramcar to transport materials or hauling people and vehicles to transport personnel. Because the battery life is limited by the power supply capacity, it is suitable for short-distance transportation.
12 tons battery electric locomotiveon the road with a slope of less than 3 ‰, the maximum pulling force can reach 120 tons.
2. model meaning
battery electric locomotives, and different types of battery electric locomotives are suitable for different use requirements.
takes CTY8 as an example, and its complete model code is CTY8/6GB.
CTY refers to the mining battery electric locomotive, such as CTL is a dual cab.
the first number (8) represents the tonnage of the model, the main models are CTY2.5, CTY5, CTY8, CTY12 and so on.
slash represents the gauge, generally 6, 7 and 9 represent 600mm, 762mm and 900mm respectively.
G refers to the steel wheel. At the same time, G also represents resistance speed regulation, GB is chopper speed regulation, and GP is frequency conversion speed regulation.
3. battery electric locomotive
battery electric locomotive isFrame,Travel device,braking device,controller,Traction motor,power supply unitand other equipment such as speakers.
Frame: The frame is divided into two parts: the cab and the body. The driver's cab is the control center of the battery electric locomotive, in which the driver's controller, horn and direct transformer are installed. The car body is the main body of the battery locomotive, and is equipped with a walking device, a braking device, a traction motor, and a power supply device.
controller: The control core of the battery electric locomotive, resistance speed regulation, chopper speed regulation and frequency conversion speed regulation three, the latter two have explosion-proof type and ordinary type.
power supply unit: To provide energy for battery electric locomotives, there are ordinary lead-acid batteries, maintenance-free batteries and lithium batteries to choose from.
Traction motor: The power source of battery electric locomotive includes DC motor and AC motor, as well as explosion-proof type and ordinary type.
4. Configuration Selection
In addition to different tonnage models, there are also explosion-proof battery electric locomotives specially used in coal mines and other mines with explosion risks. In addition, battery electric locomotive and gauge, speed control mode, braking mode, working voltage and other configurations need to choose.
speed control mode optional: In terms of cost, frequency conversion speed regulation> chopper speed regulation> resistance speed regulation. In addition, according to the actual mine conditions, if it is a coal mine, resistance speed regulation cannot be used, because it is easy to cause sparks during operation and there are potential safety hazards. It is recommended to use chopper speed regulation or frequency conversion speed regulation. At the same time, in order to achieve the effect of energy saving, it is also recommended to use chopper speed regulation and frequency conversion speed regulation, resistance speed regulation relative energy consumption. And the coal mine is required to be equipped with a gas cut-off instrument.
braking mode optional: air brake, hydraulic brake, mechanical brake three ways. Mechanical braking is the basic braking method and will be installed on all electric locomotives. Hydraulic brakes are mostly used for 3-5 tons of electric locomotives, and air brakes are mostly used for electric locomotives of 6 tons and above. In addition, electric braking can be selected as an auxiliary braking method.
locomotive power optional: ordinary lead-acid power supply, maintenance-free power supply, locomotive lithium power supply. Ordinary lead-acid power supply charging requires acid and water, the charging time is up to 8-10 hours, the working time is 8 hours, and the service life is 1-2 years. The maintenance-free power supply does not need to be charged with water, the maintenance is simple, the charging time also takes about 8-9 hours, the working time is more than 8 hours, and the service life is 1-2 years. The lithium power supply does not need to add water and is maintenance-free. It can be fully charged in 2-3 hours, working time is more than 8 hours, and the service life is 5-8 years.
support locomotive customization and modification: We can provide customers with customized production of locomotives, such as: wire storage battery dual-purpose power locomotives, special tool locomotives. It also provides the transformation of electric locomotives, for example, the control mode of locomotives is changed from ordinary resistance to chopper speed regulation or frequency conversion speed regulation, the ordinary mechanical brake is changed to hydraulic brake or air brake, the load capacity of locomotives is improved, and the ordinary power supply of locomotives is changed to lithium power supply, etc.
5. conditions of use
