Power distribution cabinet for treating three-phase imbalance

Abstract

A power distribution cabinet for treating three-phase imbalance disclosed by the invention comprises a base, the upper end of the base is fixedly connected with a cabinet plate, the upper end of the cabinet plate is fixedly connected with a cabinet top plate, the right end of the cabinet plate is movably connected with a cabinet door, the outer side of the cabinet door is fixedly provided with a spring lock and a perspective window, the inner side surface of the cabinet plate is fixedly connected with a clamping hook, the inner side surface of the cabinet plate is movably connected with a spiral seat, the outer side of the spiral seat is fixedly connected with a placing plate, and the inner side of the placing plate is movably connected with an extension plate. When the power distribution cabinet is used, the base is fixed on a horizontal plane, the placing plate is assembled or stored according to the placing position of the device and the connection of the circuit in the power distribution cabinet, when the placing plate needs to be assembled, the placing plate is rotated by 90 degrees through the spiral seat, then the extension plate on the inner side of the placing plate is pulled into a fixing rail, and therefore the position of the placing plate is fixed, and the needed device or the connected circuit can be placed at the upper end of the assembled placing plate.

Description

technical field [0001] The invention relates to the related technical field of power distribution cabinets, in particular to a power distribution cabinet for controlling three-phase unbalance. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The power distribution cabinet is the collective name of the motor control center. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. This level of equipment should provide protection, monitoring and control for the load. The final level of power distribution equipment is collectively called lighting power. Distribution boxes, which are far away from the power supply center, are scattered small-capacity power distribution equipment. [0003] When the existing power distribution...

AI Technical Summary

Problems solved by technology

[0003] When the existing power distribution cabinet handles the three-phase unbalance, the internal device needs to calculate and distribute the power consumption, which leads to the long-term high-efficiency operation of the device, which will generate a lot of heat during operation. When the heat cannot When the power distribution cabinet is discharged in time, it is easy to cause the devices in the power distribution cabinet to fail due to excessive heat, resulting in the failure of the normal operation of the devices in the power distribution cabinet, and the existing power distribution cabinet needs to be placed according to the connected electrical ports and devices. , to customize special power distribution cabinets from manufacturers, which cannot be mass-produced
