Problems solved by technology

[0002] Modern electric locomotives are driven by DC 110 volts. Therefore, if the power used by the electronic devices of the locomotive network control system still adopts the traditional method of changing from DC to AC, and then from AC to a DC power supply that meets the needs, the conversion process is too cumbersome. At the same time, the traditional The power supply for the locomotive is not electrically isolated, which is prone to electric shock accidents, and the power unit is also easily damaged

Abstract

The invention discloses a power supply plug-in connector for an electronic device of a locomotive network control system. The connector is characterized by comprising a transformation rectifying and filtering module, a +3.3V direct current power module, a +5V direct current power module and a +5V voltage module with electrical isolation, wherein the +5V voltage module is used for converting direct current voltage provided by the transformation rectifying and filtering module into +5V direct current voltage and realizing electrical isolation so as to meet the power supply requirement of a special power supply device. Due to the adoption of the technical scheme, a 110V direct current power supply used by a locomotive is directly converted into the needed +3.3V direct current power supply and +5V direct current power supply, +5V voltage output with the electrical isolation is provided, and the requirement on the power supply of the electronic device of the locomotive network control system is met.

Description

technical field [0001] The invention relates to an electronic device of a locomotive network control system, in particular to a power supply plug-in for the electronic device of a locomotive network control system. Background technique [0002] Modern electric locomotives are driven by DC 110 volts. Therefore, if the power used by the electronic devices of the locomotive network control system still adopts the traditional method of changing from DC to AC, and then from AC to a DC power supply that meets the needs, the conversion process is too cumbersome. At the same time, the traditional The locomotive power supply is not electrically isolated, which is prone to electric shock accidents, and the power unit is also easily damaged. Contents of the invention [0003] The technical problem to be solved by the present invention is: directly convert the 110V DC power used by the locomotive into the required +3.3V DC power and +5V DC power, and provide +5V voltage output with el...
