Abstract

The invention relates to the technical field of urban rail transit power supply systems, and discloses urban rail transit low-voltage power distribution system management and control equipment which comprises a machine shell, wherein a guide rod is fixedly connected to the inner top of the machine shell, a telescopic mechanism is slidably connected to the interior of the machine shell, and a reset rope is fixedly connected to the left side of the telescopic mechanism. According to the urban rail transit low-voltage power distribution system management and control equipment, an inner wheel stops rotating when the equipment is powered off, a buffer spring drives a sleeve rod to slide leftwards, the sleeve rod drives a push rod to move leftwards, the push rod drives a screw to move leftwards, the screw drives a display to swing to a horizontal position, a reset rope drives a telescopic mechanism to slide leftwards at the moment, the telescopic mechanism drives a display to slide leftwards, meanwhile, the telescopic mechanism drives a transmission rod to swing, the transmission rod drives a supporting mechanism to swing, and then the supporting mechanism is used in cooperation with the machine shell, so that the effects of automatically stretching and retracting equipment and saving space are achieved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit power supply systems, in particular to management and control equipment for low-voltage power distribution systems of urban rail transit. Background technique [0002] The power supply system of urban rail transit is from the power system through the high-voltage transmission network, the step-down of the main substation, the step-down of the power distribution network and the traction substation, and the commutation (conversion to direct current), etc., to the EMU running on the urban rail rapid transit line The entire power supply system for group transmission of electricity, among which the establishment of an urban rail transit low-voltage power distribution system with intelligent characteristics of "self-healing, integration, prediction, and optimization" is an important guarantee for improving the normal operation and scientific management and control of rail transit. [0003] At...
