Subway power supply system bilateral inter-tripping function research line protection device

Abstract

The invention relates to the technical field of subway power supply system research, and discloses a subway power supply system bilateral inter-tripping function research line protection device whichcomprises a lower protection shell. The top of the lower protection shell is rotatably connected with an upper protection shell, and the upper protection shell is rotatably connected with the top of the lower protection shell through a hinge. Air holes are formed in the front side of the upper protection shell, and moving grooves are formed in the left sides and the right sides of the lower protection shell and the upper protection shell. According to the subway power supply system bilateral inter-tripping function research line protection device, a clamping block slides into a clamping grooveto realize fixation of a sliding block so that a clamping plate fixedly supports a flat-head power plug line, and meanwhile, the clamping plate can fixedly support the flat-head power plug lines withdifferent heights through up-down movement of the sliding block; and the situation that the power lines are intertwined together is reduced so that researchers can know the power plug of each line more clearly.

Description

technical field [0001] The invention relates to the technical field of research on a subway power supply system, in particular to a line protection device for research on double-sided jumping functions of a subway power supply system. Background technique [0002] The subway is an important transportation infrastructure in my country. With the development of my country's subway industry in recent years, it has more perfect features in system design. At present, the power supply system used in my country's urban rail is mainly double design. It also has a more complete feature. At present, the power supply system used in my country's urban rail is mainly realized by two lines. In the process of research on the double-line jump function of the subway power supply system, a variety of electrical appliances need to be used, so that the subway power supply system There are many lines in the study of double-sided joint jump function; and the flat power plugs of some instruments used...

[0002] The subway is an important transportation infrastructure in my country. With the development of my country's subway industry in recent years, it has more perfect features in system design. At present, the power supply system used in my country's urban rail is mainly double design. It also has a more complete feature. At present, the power supply system used in my country's urban rail is mainly realized by two lines. In the process of research on the double-line jump function of the subway power supply system, a variety of electrical appliances need to be used, so that the subway power supply system There are many lines in the study of double-sided joint jump function; and the flat power plugs of some instruments used in the research of double-sided joint jump function of subway power supply system are inserted on the plug board; but the flat power plug of some instruments is on the plug board, which is prone to plugging If it is loose, the electrical appliances used by the researchers will be cut off, and the research data of the researchers will be lost. At the same time, the electrical appliances will be short-circuited, and the electrical appliances will be damaged.
