Abstract

Disclosed is a double-track electrified railway section post main wiring with a capacitive electrical device. By means of the main wiring, current distribution of a traction network can be improved effectively, the requirement of the current-carrying capacity of an overhead line system in a heavy vehicle direction can be reduced, the utilization rate of the current-carrying capacity of an overhead line system in a light vehicle direction can be improved, the voltage level and the power supply capacity can be improved, and electric energy losses of the traction network can be reduced. The main wiring comprises a switch type device and the capacitive electrical device, and the capacitive electrical device connects the overhead line systems in light and heavy directions in series at the tail end of a power supply arm through the switch type device.

Description

technical field [0001] The invention relates to an electrified railway division, in particular to a main wiring of a double-track electrified railway division with capacitive electrical equipment. Background technique [0002] Double-track electrified railways usually have a division station at the end of the power supply arm. The electrical main wiring of a conventional substation only includes switch equipment, and the uplink and downlink catenary of the connected power supply arm can be connected in parallel up and down through the switch equipment. The cross-zone switch set between the power supply for cross-zone. [0003] Parallel operation of partition stations can reduce the equivalent impedance of the traction network and improve the traction power supply capacity; improve the current distribution of the traction network and reduce the current carrying capacity demand of the traction network in the direction of heavy vehicles. , the better the improvement effect; r...
