能馈式牵引供电装置在矿井辅助运输中的应用

Application of Energy Feedback Type Traction Power Supply Device in the Coal Mine Auxiliary Transportation System

煤矿辅助运输中,直流牵引供电系统有逐步代替传统蓄电池、柴油机牵引的趋势,当采用直流牵引供电系统时,也会遇到在城轨交通中遇到的谐波问题、功率因数问题及再生制动能量的耗散问题等。能馈式牵引供电装置同时具备牵引整流、能量回馈功能,功率因数高,节约电能,已在城轨交通中得到广泛应用,具有推广到矿井辅助运输系统中的价值。

In the coal mine auxiliary transportation system,the DC traction power supply system has a tendency to gradually replace traditional batteries and diesel traction system. When the DC traction power supply system adopted,the harmonic problems,power factor problems and dissipation problems of regenerative braking energy in the urban rail transit are also encountered in the auxiliary transportation system. The energy feedback type traction power supply device has the traction rectifier and energy feedback function,has the advantage of high power factor and energy-saving. The device has already wildly used in the urban rail transit,has the value of promotion to the mine auxiliary transportation system.
