Example Embodiment

[0016] 1. Main functions and performance indicators of the overall structure

[0017] The whole is composed of a chassis 1, a terminal block 2, a plug connector 3, a switch indicator 4, and two inverter voltage regulator circuit boards 5 (see figure 1 ). One circuit board 5 outputs 50V, 25W, and the other outputs 50V, 100W.

[0018] Inverter voltage stabilizer circuit: Invert the railcar's 24V DC power supply to 48V±2V DC power supply.

[0019] Wiring terminal: The 48V±2V DC power supply is output to each plug connector through the wiring terminal.

[0020] Plug-in connector: supply 48V±2V power to the connected locomotive signal host, self-stop device, signal display mechanism and other equipment.

[0021] Switch indication: The I terminal, II terminal wiring and related indicator lights, power switch indication will be displayed respectively.

[0022] Main functions: One is to provide 48V±2V, 25W DC power supply and self-stop device to provide 48V±2V, 100W DC power supply for t...

Abstract

The track vehicle locomotive signal power supply connection box is mainly characterized by that it incldues machine box and connecting terminal mounted on the medicine shell, plug connector and switching representation and inverse transformation voltage-regulating circuit board, the inverse transformation voltage-regulating circuit structure is as follows: the locomotive power supply 24V is passed through fuse and precondenser filter to remove noise water, the passed through voltage-stabilizing integrated circuit to stabilize voltage, the voltage-stabilized power supply is passed through pi-type filter condenser and fed into power supply inverse transformation voltage-stabilizing integrated block, after inverse transformation the obtained output power supply 50 V is passed through post filter condenser to make filtering.

Description

Technical field: [0001] The invention relates to a locomotive power conversion and wiring distribution electrical device. Background technique: [0002] With the development of railway transportation, the speed of trains is gradually increasing, and the density of trains is gradually increasing. The new mode of transportation brings new challenges to railway maintenance and production. The contradiction between the safety of maintenance and production and the mode of transportation has become increasingly prominent. Improve the quality and speed of maintenance and production, and add a large number of small locomotives such as power railcars and rescue vehicles. There are nearly 100 locomotives in Shijiazhuang Branch alone, and more than 400 locomotives in Beijing Railway Bureau. They are used in accident rescue and material transportation. , engineering construction and maintenance production and other work has played an irreplaceable role. [0003] However, due to the con...
