Description

An improved power distribution control box

Technical Field

The utility model relates to the technical field of power distribution control boxes, in particular to an improved power distribution control box.

Background Art

The distribution box is divided into power distribution box, lighting distribution box and metering box. It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is suitable for occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This set of equipment should provide protection, monitoring and control for the load.

For example, the utility model patent with application number 202222809823.1 discloses an improved power distribution control box. The utility model allows the lighting tube to move up and down by moving the slider, and changes the lighting direction of the lighting tube by rotating the rotating tube, which is convenient for the device installed in the box. In addition, the lighting tube can be taken out of the rotating tube, and the lighting tube can be held by the maintenance personnel at this time, which avoids the situation that when the lighting tube illuminates the internal device, the part to be operated is in the shadow, which makes it inconvenient to operate the operating part, thus affecting the maintenance or inspection of the device inside the distribution box. However, in the power distribution control box, the electrical components inside the box are assembled inside the rear side of the box. When manually inspecting and maintaining the electrical components in the box, it is necessary to bend over and reach into the box to operate. However, the internal space of the box is small and there are a lot of wiring, which greatly affects the manual maintenance and inspection of the electrical components. The maintenance process is more troublesome and less practical.

Therefore, in view of this, the existing structural deficiencies are studied and improved, and an improved distribution control box is proposed.
