Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] refer to figure 1 , a mutual backup power supply system for locomotives, comprising a spare train supply cabinet and an inverter cabinet.

[0020] The standby train supply cabinet is a DC600V direct power supply device, the input terminals of which are respectively connected to the AC power supply and the reactor, and the output terminals are respectively connected to the inverter cabinet and the original power supply system of the locomotive. When the...

Abstract

The invention discloses a locomotive mutual backup power supply system, and the power supply system comprises a standby cabinet and an inverter cabinet. The standby cabinet is a DC600V direct power supply device, is connected with two power conversion knife switches, and carries out the switching of a main loop input power supply and a main loop output filter reactor of the DC600V direct power supply device. The two power conversion knife switches are three-pole and double-throw switches, have an interlocking function, and prevent the electric crosstalk of a rectification loop. The DC600V direct power supply device is a three-phase full-bridge half-control silicon controlled rectifier phase control rectification device. The interior of the inverter cabinet is provided with an inversion power supply, and the inversion power supply is an IGBT three-phase full-bridge inversion device. When an inverter detects that the air pressure of a main air reservoir is not sufficient, the inverter outputs a 3AC380V alternating current to a compressor. When the inverter detects that the air pressure of the main air reservoir is sufficient, the power supply is stopped, so as to guarantee that the air pressure of the main air reservoir is sufficient. When an original locomotive has a power fault, the power can be switched to the standby power supply, so as to guarantee the normal operation of the locomotive.

Description

【Technical field】 [0001] The invention relates to the technical field of locomotive power supply, in particular to a locomotive mutual backup power supply system. 【Background technique】 [0002] The locomotives pull passenger trains, and the locomotives are equipped with train supply cabinets that generally have two sets of independent power supply systems with a power of 400KW to provide DC600V DC power to the vehicles to ensure that passengers can ride safely and comfortably. Once a certain power supply system fails, the vehicle must run with reduced load, which will affect the travel life of passengers, and the current locomotive system has not yet solved this problem well. 【Content of invention】 [0003] In view of this, in order to overcome the deficiencies of the prior art, the present invention provides a locomotive mutual backup power supply system, which is applied to locomotives and can ensure the normal power supply of the train when the circuit system fails, an...
