Problems solved by technology

However, the frictional fit between the door and the cover plate of some distribution boxes of this structure cannot ensure the locking of the door stably, and the door often falls and closes by itself under the action of gravity, or the door and cover plate of some distribution boxes are too tightly fitted. Causes a lot of friction and the operator has to work hard to close the door

Embodiment Construction

[0016] Please refer to figure 1 , figure 1 It is a schematic diagram when the distribution box of the present invention is not opened. From figure 1 It can be seen from the figure that the distribution box in this embodiment includes a bottom plate (not shown in the figure), a top plate 1, a rear plate (not shown in the figure), a left side plate (not shown in the figure), a right side plate 2 and a front door 3. The bottom plate, top plate 1, rear plate, left side plate, right side plate 2 and front door 3 form a cuboid box structure. This cuboid box has a simple and reasonable design, takes up less space, and has a more reasonable appearance layout. The left side panel, the right side panel 2 and the front door 3 include shutters with openings downwards, figure 1 The shutters 20 and 30 on the right side panel 2 and the front door 3 are shown in . Due to the setting of the louvers, the distribution box can effectively dissipate heat, thereby ensuring a suitable working te...

Abstract

The invention provides a power distribution box comprising a bottom plate, a top plate, a rear plate, a left side plate, a right side plate, and a front door which form a cubic box body structure. The left side plate, the right side plate, and the front door comprise shutters with downward openings. The power distribution box has characteristics of simple and reasonable power distribution box, decrease in occupied space, reasonable appearance arrangement, easy opening and closing, and convenient and flexible installation and disassembly. The shutters with downward openings enable effective heat dissipation of the power distribution box so as to guarantee appropriate operating temperature.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a power distribution box. Background technique [0002] Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions. Commonly used in various power generation, distribution and substations. Existing distribution boxes generally include a ...
