Electromechanical control system of high-power and low-speed battery towing vehicle

Abstract

The invention discloses an electromechanical control system of a high-power and low-speed battery towing vehicle and relates to the technical field of locomotive power. More particularly, the invention belongs to the electromechanical control system of the high-power and low-speed battery towing vehicle used for a short-distance transfer and shunting operation. The electromechanical control system of the high-power and low-speed battery towing vehicle comprises a battery pack, a charging cabinet, a power distribution box, an electronic control cabinet and a conversion cabinet which are mounted on the high-power and low-speed battery towing vehicle on a shunting track, wherein a 560 V DC output from the battery pack is connected to a circuit breaker of the power distribution box through a conversion terminal of the charging cabinet, and then is output to the electronic control cabinet through the circuit breaker; and the electronic control cabinet respectively outputs three branch circuits comprising a first branch circuit, a second branch circuit and a third branch circuit. In conclusion, the electromechanical control system of the high-power and low-speed battery towing vehicle has the characteristics of high reliability, sensitive operation, long service life, flexible combination of many output nodes and far operation distance, and has the advantages of effectively saving the manpower and production cost, improving the work efficiency and protecting the environment.

Description

technical field [0001] The invention relates to the technical field of locomotive power, in particular to an electromechanical control system for a high-power and low-speed battery tractor applied to a small-running shunting locomotive. Background technique [0002] At present, small tractors under 20 tons are widely used in domestic coal mines, highway tunnels, etc. It has the characteristics of maneuverability, flexibility, reasonable structure and layout, safe and reliable driving operation and small maintenance. At the same time, the inverter also has various protection functions such as undervoltage, overvoltage, overheating, overcurrent, overspeed, etc., as well as braking deceleration charging function, full speed control and electrical braking function, etc. The safety of locomotive use is improved to the greatest extent, and the occurrence of safety accidents is reduced or even avoided. The advantages of low power supply cost, no spark, easy explosion-proof, energy...
