Explosion-proof battery electric locomotive is an important means of transportation in production, which has already been put into our life in large quantities and has a wide range of applications. It is used in many industries, such as petroleum, chemical, natural gas, pharmaceuticals, etc. In recent years, DC can not meet the needs of use, and AC has gradually replaced DC. So what are the advantages of communication?
Higher reliability:
The locomotive of this system adopts three-phase AC asynchronous motor, which is not easy to be damaged because of the wireless coil on the rotor of the motor and the commutation copper head. In addition, the controller has no contact wear.
The traction performance is better:
When starting at low frequency (1HZ), the starting torque can reach 300% of the rated value, and the starting torque and traction characteristics of AC asynchronous motor can reach and exceed that of DC motor. The traction force of AC asynchronous motor is 1.6 times that of ordinary DC motor. It meets the maximum starting traction of locomotive at low speed and makes the locomotive start with heavy load strong.
