Abstract

A large-tonnage tunnel engineering heavy haul train electrical control system comprises a storage battery power source, a main motor variable frequency driver, a slave motor variable frequency driver,a switch power source system, a PLC, a main traction motor, a slave traction motor, a touch screen, an audible and visual alarm assembly, a video monitor, a train lamp control assembly, an auxiliaryvariable frequency driver, an air compressor and a brake resistor. Both the main motor variable frequency driver and the slave motor variable frequency driver are connected with the storage battery power source. The main motor variable frequency driver and the slave motor variable frequency driver are connected. The main motor variable frequency driver is connected with the main traction motor. The slave motor variable frequency driver is connected with the slave traction motor. Both the main motor variable frequency driver and the slave motor variable frequency driver are connected with the brake resistor and the PLC. Compared with an existing vehicle, the large-tonnage tunnel engineering heavy haul train electrical control system achieves anti-dozing, fault detection, single-motor and double-motor selection functions, redundant energy is emitted through the brake resistor, and work reliability is high.

Description

technical field [0001] The invention relates to the electrical control of heavy-duty trains, in particular to an electrical control system for heavy-duty trains in large-tonnage tunnel engineering.
