Junction box for signal power source of track vehicle and locomotive

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...

Problems solved by technology

[0003] However, due to the constraints of many types of powered railcars, small size, and low power supply voltage, locomotive signals and automatic parking devices are not installed, which brings great inconvenience to the driving work of railcar drivers, especially in rain, snow, It is impossible to confirm the signal when driving in foggy days, at night and at curves, and it is easy for the driver to doze off, misidentify the signal or run at overspeed, causing accidents such as various locomotive crashes, off-lines, squeezes and rushing into the signal, which has become a major problem in transportation production. a big hidden danger
