Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Such as figure 1 As shown, based on the trolley line power supply method for electric locomotives in the depot, the trolley line 2 is set above the track of the electric locomotive 5 in the depot, and the intelligent control box 4 is set on the collector trolley 3 of the trolley line 2, and the ground power distribution Room 1 provides an AC 380V or DC 600V power supply to connect to the trolley line 2, and the intelligent control box 4 introduces power from the trolley line 2, and then sends it to the on-board power socket 6 of the electric locomotive through the power connection line 7. By setting the trolley line above the electric locomotive, a convenient and quick power supply line is provided for the electric locomotive. Just connect the power supply to the trolley line, and then you can take power from any position of the entire t...

Abstract

The invention discloses a method and a device for power supply for locomotive running in an electric locomotive shed based on trolley conductors. The trolley conductors are arranged above electric locomotive rails in the shed, an intelligent control cabinet is arranged on a current collection trolley for the trolley conductors, a ground power distribution room provides an alternating-current 380V or direct-current 600V power source to be accessed to the trolley conductors, the intelligent control cabinet is led in the power source from the trolley conductors, and power is transmitted to an electric locomotive vehicle-mounted power source socket through a power transmission line so that an electric locomotive is powered. Compared with conventional cable power supply, the method and the device have the advantages of high efficiency, convenience in mounting and movement and capability of achieving individual operation.

Description

technical field [0001] The invention relates to a power supply method and system for electric locomotives, in particular to a method and system for power supply of electric locomotives in maintenance depots. The method and system are based on trolley wire power supply. Background technique [0002] With the rapid development of my country's railway electrification, my country's railway locomotive traction has also undergone qualitative changes. Electric locomotives that have shifted from DC traction to AC traction have become more and more widely used, forming an AC-DC-AC power supply mode. Today's electric locomotives need to go through various strict inspections and tests before leaving the factory or leaving the section. Many of the inspections and tests require a power supply, and most of them require a 600V DC power supply for power supply, and a few also require a 380V AC power supply. On the other hand, the electric locomotive also needs a temporary 600V DC power supp...
