Problems solved by technology

[0004] This system needs to lay fixed launching devices along the railroad track, which is huge in number and very high in cost; and when the electric locomotive passes through different locations, it needs to activate the fixed launching Control the open and close state, the control is complex; and because the transmitter is fixed, when the fixed transmitter and the vehicle receiver are staggered, the transmission efficiency will be reduced

Embodiment 1

[0051] The invention provides a non-contact power supply system for electric locomotives, see figure 1 as shown, figure 1 A schematic structural diagram of a non-contact power supply system for electric locomotives provided by the present invention; the system includes:

[0052] High-frequency current generating device 11, used to provide high-frequency alternating current;

[0053] The high-frequency AC guide rail 12 connected to the high-frequency current generating device 11 and the movable transmitting device 13 is used to receive high-frequency alternating current and transmit it to the movable transmitting device 13; it is also used as a moving track for the movable transmitting device 13;

[0054]The movable transmitting device 13 that can keep running at the same speed as the corresponding vehicle-mounted receiving device 14 is used to receive high-frequency alternating current and perform electromagnetic conversion to generate a magnetic field;

[0055] The on-board...

Embodiment 2

[0058] Based on the first embodiment, the present invention also provides another non-contact power supply system for electric locomotives.

[0059] Preferably, the vehicle-mounted receiving device 14 is in one-to-one correspondence with the movable transmitting device 13 .

[0060] It can be understood that, at this moment, the quantity of the movable transmitting device 13 is equal to the number of cars of the electric locomotive (one vehicle receiving device 14 is arranged on each car). The problem of low transmission efficiency caused by the non-correspondence of the device 14. In addition, it is also possible to adopt a mode in which one mobile transmitter 13 corresponds to multiple vehicle-mounted receivers 14, which can further reduce the number of mobile transmitters 13 and reduce costs; in addition, in this case, one mobile transmitter 13 The number of the corresponding vehicle-mounted receiving devices 14 and the installation position of the movable transmitting dev...

Abstract

The invention discloses a non-contact power supply system for an electric locomotive. The non-contact power supply system comprises a high-frequency current generation apparatus, a high-frequency alternating current guide rail, mobile transmitting apparatuses, and vehicle-mounted receiving apparatuses, wherein the high-frequency current generation apparatus is used for providing high-frequency alternating current; the high-frequency alternating current guide rail is connected with the high-frequency current generation apparatus and the mobile transmitting apparatuses separately, used for receiving the high-frequency alternating current and transmitting the high-frequency alternating current to the corresponding mobile transmitting apparatuses, and also can be used as the mobile guide rail of the corresponding mobile transmitting apparatuses; the mobile transmitting apparatuses can run at the same speed as the vehicle-mounted receiving apparatuses, and are used for receiving the high-frequency alternating current and then performing electromagnetic conversion to generate a magnetic field; and the vehicle-mounted receiving apparatuses are used for performing magneto-electricity conversion in the magnetic field to generate first alternating current, and converting the first alternating current into the electric energy required by the electric locomotive. According to the non-contact power supply system, the adopted mobile transmitting apparatuses can run at the same speed as the corresponding vehicle-mounted receiving apparatuses, so that a large amount of pavement of the mobile transmitting apparatuses is not required, and low cost is achieved; meanwhile, the non-contact power supply system is simple to control; and the dislocation probability between the mobile transmitting apparatuses and the corresponding vehicle-mounted receiving apparatuses is extremely low, so that high transmission efficiency of the non-contact power supply system is realized.

Description

technical field [0001] The invention relates to the technical field of power supply for electric locomotives, in particular to a non-contact power supply system for electric locomotives. Background technique [0002] During the operation of the electric locomotive on the railway, the electric energy is obtained through the connection between the pantograph and the catenary. During the operation of the electric locomotive, the pantograph is prone to wear, aging and other problems, which indirectly causes ignition phenomena such as electric sparks or arcs. In weather such as rain and snow, the generation of contact sparks will bring huge safety hazards to the operation of electric locomotives and endanger the safety of staff. [0003] The existing non-contact power supply system for electric locomotives mostly adopts magnetic induction coupling wireless power transmission technology, which is composed of a fixed transmitter, a vehicle-mounted receiver, and a high-frequency alt...
