Movable emergency direct current power cabinet

Abstract

The invention discloses a movable emergency direct current power cabinet, wherein a power cabinet body comprises a charging and feeding cabinet and a battery cabinet, vertical columns are arranged at four corners of the cabinet body, the charging and feeding cabinet is electrically connected with the battery cabinet, and multiple layers of battery devices are arranged in the battery cabinet. Each battery device comprises a battery supporting plate and battery installation grooves distributed in the battery supporting plate fixedly in a matrix mode. Supporting columns are arranged among adjacent vertical columns, and a movable device is arranged at the lower portion of the cabinet body. A hoisting ring is arranged at the top of the cabinet body, so that hoisting during transportation of the direct current power cabinet is facilitated. The movable device is arranged at the bottom of the cabinet body and replaces universal wheels directly arranged at the bottom of the power cabinet, therefore, unreliable rolling and easy damage caused by too-small wheels are avoided, and unsteady gravity of the cabinet body caused by too-large wheels is avoided. The battery supporting plate is reinforced by the supporting columns, and gravitational deformation possibly occurring during usage of the power cabinet is avoided.

Description

Technical field: [0001] The invention relates to a mobile emergency DC power supply cabinet, which belongs to the technical field of electric equipment. Background technique: [0002] The DC system is an independent power supply, which is not affected by the generator, plant power consumption and system operation mode, and in the event of an external AC power interruption, it ensures that the backup power supply continues to provide DC power for important equipment and the reliability of the DC screen , Security directly affects the reliability and security of power system power supply. At present, DC panels in substations and power plants are generally composed of battery packs, high-frequency switching power supply modules, feeder circuit breakers, related DC monitoring and monitoring devices, instruments, and protection modules. In the factory station, the screen cabinet is fixed. The fixed power cabinet cannot be moved due to its large size and heavy weight. Oriented w...

AI Technical Summary

Problems solved by technology

In the factory station, the screen cabinet is fixed. The fixed power cabinet cannot be moved due to its large size and heavy weight. Orientation wheels, if the wheels are too small, they cannot roll reliably and are easily damaged. If the wheels are too large, the center of gravity of the cabinet will be unstable, which is not conducive to transportation. In addition, the cabinet is prone to gravity deformation during the moving process
