Embodiment Construction

[0019] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0020] figure 1 It is a schematic diagram of the equipment structure of the automatic phase separation of the locomotive provided by the present invention, as figure 1 As shown, the device includes a voltage comparator and a controller. A voltage comparator is connected to the secondary side of the voltage transformer connected to the catenary, the voltage comparator compares the secondary voltage of the voltage transformer with a preset voltage, and outputs the comparison result in the form of an electric signal. The controller is connected with the voltage comparator, and is used for controlling the opening and closing of each auxiliary machine (with multipl...

Abstract

The invention discloses a locomotive neutral-section automatically-passing device and method. The device comprises a voltage comparator and a controller, wherein the voltage comparator is connected with the secondary electrode of a voltage transformer connected to a catenary, compares the second voltage of the voltage transformer with a presser voltage and outputs the comparing result in a mode of an electric signal; the controller is connected with the voltage comparator and controls the on and off of auxiliary machines connected to the controller according to the comparing result. According to the locomotive neutral-section automatically-passing device, by arranging the voltage comparator between the controller and the voltage transformer, whether a locomotive is in the neutral section of the catenary can be determined, so that the controller can control the on and off of the auxiliary machines according to the determining result, and further auxiliary machine circuit over-current and main circuit breaker tripping due to the over-current can be effectively avoided.

Description

technical field [0001] The invention relates to an automatic phase separation technology, in particular to a device and method for automatic phase separation of a locomotive. Background technique [0002] The traditional electrified railway adopts the method of manual power-off and over-phase separation. The crew needs to frequently look at the over-phase signs to manually perform the over-phase operation. Locomotive faults such as neutral section. [0003] In order to overcome the above problems, the technology of automatic over-phase separation is usually used now. In the process of automatic over-phase separation control, the electric locomotive is controlled by the ground phase separation device and needs to go through a process of power-off and power-on. During this process, the main and auxiliary circuits of the locomotive will generate inrush current and loss of voltage, so the locomotive will take a protective action, that is, the main circuit breaker will trip. In...
