The advantages of frequency conversion speed regulation of battery electric locomotives are as follows:Non-contact switching elements in the circuit; excessive starting current is eliminated to prevent damage to the motor due to overcurrent. Due to the perfection and stability of various protection mechanisms of the inverter, the AC motor is never damaged by overcurrent, and the fuses in the circuit are rarely blown, thus prolonging the service life of the battery. The suppression of overcurrent and the use of non-contact switches both reduce the burden on the explosion-proof structure of the AC electric locomotive, reduce its complexity, increase reliability, and make the manufacturing cost relatively low
    The 8 ton tunnel battery locomotive's mode is CTY8/6,7,8GB, which is include common type, underground explosion-proof and ground -engineering truck type,have big traction,high speed, strong carrying capacity.

    The traction capacity is about 80 ton. 

    The explosion-proof of 8 ton battery locomotive special type is applicable to the high gas coal mine which can produce 1.2 million tons per year. Speed controller have two kinds include chopper and variable frequency types, with mechanical, electric, and air brake, Be able to install gas alarm to cut off electric instruments for protection according to customers’ requests, which is more safer and reliable, and can adopted double cab that can makes better outlook.

There are four common models of explosion-proof battery electric locomotives: CTY2.5, CTY5, CTY8, and CTY12. The numbers represent the tonnage of the corresponding models, and can also be customized if required. In addition, depending on the configuration, there are some detailed divisions. For example, the gauge is 600mm, 762mm, 900mm, the control methods include chopper speed regulation and frequency conversion speed regulation, and the braking methods include mechanical braking, hydraulic braking and air braking.
