Application of energy-efficient rectifiers of traction substations of railway quarry transport

Shows ways to increase the energy efficiency of traction transformative substations (CCIs) in the power supply networks of contact electric locomotives of mountain and mine (mine) enterprises. It was noted that the reasons for reducing the supply voltage at the output of CCI in the power supply networks of energy equipment of mining enterprises, mine (mine) contact electric locomotives. Which leads to voltage loss at the most remote points of the contact network. The main ways to stabilize the supply voltage at the output of traction transformative substations in the power supply networks of energy equipment of mining enterprises, mine (ore) contact electric locomotives. The results of the simulation tests of rectifiers allow us to compare their energy efficiency and the optimal selection of a schematic solution. It was established that the power of losses at traction transformative substations (CCIs) of mountain and mine enterprises is also characterized by the degree of distortion of the forms of the rectified current and voltage curve. The obtained results of studies of the energy characteristics of 6 and 12 pulse rectifiers can be used in the future when creating effective schematic solutions of uncontrollable rectifiers to design new ones, as well as the modernization of existing, CCA feeding ground and mine electric locomotives of eaterings.
