Problems solved by technology

However, the first method needs to adjust the marshalling according to the lines used each time, which is time-consuming and labor-intensive. At the same time, it causes a considerable workload for the marshalling adjustment; the second method increases the labor intensity of the driver and may Serious impact on the pantograph-catenary system due to misoperation by the driver

Embodiment 1

[0056] see figure 1 A schematic structural diagram of an over-phase pantograph-catenary protection device provided in Embodiment 1 of the present invention, and see figure 2 It is a schematic flow chart of an excessive phase pantograph-catenary protection method provided in Embodiment 1 of the present invention. The excessive phase pantograph-catenary protection device includes an input module 1, a control module 2, and an output module 3. The excessive phase pantograph-catenary protection method includes The following steps:

[0057] S11. The input module 1 sends the over-phase separation signal that the train arrives at the phase separation area to the control module 2;

[0058] S12. After receiving the overphase signal, the control module judges whether the train has two hoist pantographs in the two anchor joints at the end of the neutral section at the same time, and if so, the The control signal for controlling the lowering of the pantograph is sent to the output modul...

Embodiment 2

[0062] Referring to embodiment one of the present invention and figure 2 The method procedure described in , and see image 3 , image 3 It is a schematic structural diagram of an excessive phase pantograph-catenary protection device provided in Embodiment 2 of the present invention, specifically,

[0063] The excessive phase pantograph-catenary protection device also includes an excessive phase detection module 4, and the excessive phase pantograph-catenary protection method also includes:

[0064] The over-phase detection module senses the electromagnetic signal on the ground through the ground induction coil to judge whether the train has reached the phase-separation area, and if so, sends the over-phase signal arriving at the phase-separation area to the input module.

[0065] Correspondingly, the over-split phase pantograph-catenary protection device also includes a pantograph state storage module 5 and a phase-split area data storage module 6, and the method also incl...

Embodiment 3

[0085] Corresponding to the excessive phase pantograph-catenary protection method disclosed in the first and second embodiments of the present invention, the third embodiment of the present invention also provides an excessive phase pantograph-catenary protection device, see image 3 , the device includes an input module 1, a control module 2 and an output module 3, wherein,

[0086] The input module 1 is used to send the over-phase signal that the train arrives at the phase-separation area to the control module;

[0087] The control module 2 is configured to judge whether two pantographs of the train are simultaneously in the two anchor section joints at the end of the neutral section after receiving the overphase signal, and if so, set A control signal for controlling the lowering of the pantograph is sent to the output module;

[0088] The output module 3 is configured to send the control signal to a pantograph to control the lowering of the pantograph.

[0089] Correspon...

Abstract

The invention discloses a neutral-section passing pantograph-catenary protective method and device. The neutral-section passing pantograph-catenary protective device comprises an input module, a control module and an output module. The neutral-section passing pantograph-catenary protective method comprises the steps that the input module sends a neutral-section passing signal of a train arriving at a neutral section to the control module; the control module receives the neutral-section passing signal and then judges whether or not the train has two raising pantographs in two overlapping sections at the end of a neutral section at the same time, and if yes, a control signal for controlling the pantographs to drop is sent to the output module; the output module sends the control signal to one pantograph, and the pantograph is controlled to drop. Through the neutral-section passing pantograph-catenary protective method and device, the aim that when the train passes the neutral section in the pantograph raising running process, a pantograph-catenary is automatically protected and controlled is achieved.

Description

technical field [0001] The invention relates to the technical field of railway locomotives, in particular to a protection method and device for over-phase pantograph-catenary protection. Background technique [0002] The receiving grid on the railway is not provided by one power supply. Generally, one power supply is responsible for a certain area. The phase of the current between the two power supply stations is not necessarily the same, so there is a section between the two power supply grids. The "grid" without electricity, this section of the "grid" is called a split phase, and the train passing through this section is called an excessive phase. In the technical field of railway locomotives, catenary network suppression is divided into AC system and DC system. The two phase arms of the AC contactor need to be isolated through the phase separation area. In order to prevent multiple pantographs of the train from running In case of a short circuit between two phase arms of...
