Embodiment 1

[0026] figure 1 It is a structural diagram of an over-phase separation operating system of a train provided in the embodiment of the present application.

[0027] Such as figure 1 As shown, the over-phase split operating system provided in this embodiment includes an over-phase split control power supply 100, a first delay relay 10, a second delay relay 40, a first conventional relay 20, a second conventional relay 30, and a third conventional relay 50 and a fourth conventional relay 60 .

[0028] The over-phase control power supply 100 is provided with a first voltage output terminal 101 and a second voltage output terminal 102 . The first voltage output terminal 101 is used to output the control voltage. When the train is running normally, the control voltage is output. When the train receives the phase-splitting signal from the ground system, it outputs 0 volts. Control voltage: the second voltage output terminal 102 outputs 0 volts when the train is running normally, ou...

Embodiment 2

[0038] figure 2 It is a structural diagram of a train transition phase control system provided by another embodiment of the present application.

[0039] Such as figure 2 As shown, the over-phase control system provided in this embodiment includes an over-phase relay, a first delay relay, a second delay relay, a first regular relay, a second regular relay, a third regular relay and a fourth regular relay.

[0040] The following is a description of its working process:

[0041] The coils of the first delay relay B1 and the second delay relay B2 are de-energized for 2 seconds, and the contacts are disconnected, and the contacts are closed immediately after the coils are energized, and the delay time is the pulse width of the output pulse signal of the circuit. The first conventional relay C1 and the third conventional relay C2 are used to output pulses. A second conventional relay D1 and a fourth conventional relay D2. The first conventional relay C1 and the third convention...

Abstract

The invention provides a passing neutral section operating system for a train, wherein a first time delay relay, a first conventional relay and a second conventional relay constitute an inlet neutral section control circuit, when the train receives an inlet neutral section signal, a neutral section control power supply outputs 0v voltage through a first voltage output end, and outputs control voltage through the output end of a second voltage output end, so as to control a main relay to switch off through the second conventional relay; a second time delay relay, a third conventional relay and a fourth conventional relay constitute an outlet neutral section control circuit, after the train receives an outlet neutral section signal, the neutral section control power supply outputs the control voltage through the first voltage output end, and outputs 0v voltage through the second voltage output end, so as to control the main relay to close through the fourth conventional relay. Namely, the system can automatically finish switching off / closing operation to a main breaker according to the inlet neutral section signal and the outlet neutral section signal, and thus can improve the automatic level of the train.

Description

technical field [0001] The present application relates to the technical field of railway transportation, and more specifically, relates to a phase separation operating system for trains. Background technique [0002] The catenary of the electrified railway needs to maintain a stable power supply voltage, so it must be composed of multiple power supply sections, each power supply section is powered by the corresponding traction substation, and there is a section of non-electric catenary between each power supply section , called the phase separation region. The main circuit breaker needs to be disconnected when the train enters the phase-splitting area, and the main circuit breaker needs to be closed when it leaves the phase-separating area. At present, it mainly relies on the driver to manually open / close the main circuit breaker according to the over-phase signal, and the degree of automation is low. Contents of the invention [0003] In view of this, the present applic...
