Controlling means and device for automatic passing of neutral section for electric locomotive

Abstract

The invention relates to an automatic phase separation control method of an electric locomotive and a device thereof, which can simulate the driver's operation by only using on-board equipment, reliably complete the automatic phase separation process and realize optimal control. The method of the present invention comprises the following steps: according to the current position, speed and level of the handle of the locomotive, combined with the next power-off mark, it is judged whether the locomotive has entered the effective operating distance of the automatic phase separation, if so, the automatic phase separation device obtains the level control right, Reduce the level to zero; then disconnect the main circuit breaker before reaching the power-off mark; after the locomotive passes the power-off mark, close the main circuit breaker, delay for a period of time and then restore the locomotive level to the current handle level, and then Return notch control to the joystick. The device of the invention comprises a main controller, a level control module connected with the main controller, a communication interface, a main circuit breaker control module and a display box. The device can also cooperate with the smart electric meter of the locomotive to realize time-sharing and segmental metering of electric power.

Description

technical field [0001] The invention relates to an automatic over-phase separation control device for an electric locomotive, in particular to an automatic over-phase separation control device based on a TAX box (hereinafter referred to as the TAX box), a comprehensive monitoring device for locomotive safety information. Background technique [0002] When the electric locomotive is running, it obtains single-phase alternating current from the power grid erected next to the railway to provide power. The phases of the three-phase power supply of the power grid are alternately arranged on different road sections, and the insulation intersection points between the phases are called phase-splitting points. shock. The operation process of the driver when the locomotive passes the phase split is as follows: when the locomotive is far away from the phase split point, the locomotive runs normally, and the level position (corresponding to a certain locomotive current) handle is in th...

Problems solved by technology

[0004] At present, there are mainly three methods of automatic phase separation of electrified railway locomotives at home and abroad: the ground switch automatic switching method, which is composed of insulating anchor joints, non-insulating track circuits, vacuum load switch transformers, lightning arresters, power switchboards and other equipment, with locomotive disconnection The power-on time is short and can adapt to various speed requirements, but the system is very complicated, the cost is high, and the equipment maintenance cost is high; the automatic power-off mode of the switch on the column is composed of shared insulators, vacuum switches and other equipment, and the power-off time of the locomotive is short. , but when the locomotive is over-phase-splitting, over-voltage and over-current are generated, and the equipment structure is relatively complicated; the way of locomotive automatic control over-phase-splitting is different from the previous two methods. The way of not taking current is to pass through the phase-splitting point. One of the commonly used methods is to bury the point on the ground. The system consists of insulating anchor joints, ground magnets, locomotive receiving control devices and other equipment. The system is relatively simple, but in order to provide control information for the locomotive , it is necessary to bury magnets on both sides of each phase-splitting point on the railway site in advance. Excessive phase separation requirements at high speeds, and ground sensors are not easy to maintain, resulting in high maintenance costs

[0005] The above three methods should have equipment on the ground or on the pole. Real-time monitoring of these equipment cannot be carried out on the locomotive. When the equipment on the ground or on the pole fails, the device will not be able to automatically pass the phase, and it is too late for the driver to do it manually, which will easily cause electrification. Serious consequences of over-phasing and therefore less reliability
