Outdoor distribution box

Abstract

The invention relates to an outdoor distribution box. A casing is divided into an upper cavity and a lower cavity through a separator plate, and the upper plane of the casing is provided with a small hole; a lightning protection apparatus comprises a lightning protection chip and a protective cover, and the protective cover is connected with the side wall of the casing; a fire protection apparatus comprises a fire-extinguishing pot and a nozzle which are connected and is installed at the upper surface of the casing, and the nozzle is cylindrical-shaped and is inserted in the small hole in the upper surface of the casing; an electric appliance installing plate is arranged inside the casing, the installing plate is L-shaped, the plane where an L-shaped long edge is disposed is installed at the rear plane of the casing, and the plane where a short edge is disposed is installed at the bottom surface of the casing; and the installing plate and the casing are connected through a buffer spring pin. The outdoor distribution box has the following advantages: the outdoor distribution box is provided with the fire protection apparatus and the lightning protection apparatus, the apparatus structure is simple, and the safety performance is high; the buffer spring pin is installed between the electric appliance installing plate and the casing, a buffer effect is exhibited, and components inside the distribution box are protected; and an arc-shaped top plate and diversion trenches are arranged at the top portion of the outdoor distribution box, the outdoor distribution box functions well in rainy days, and the waterproof effect is good.

Description

technical field [0001] The invention relates to a distribution box, in particular to an outdoor 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 box. 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. [0003] Outdoors is one of the harsher environments for distribution boxes. Outdoor distribution boxes often need to be exposed to work outdoors, and there a...

AI Technical Summary

Problems solved by technology

The outdoor working environment is harsh, and the internal lines of the distribution box are aging relatively quickly. Often, the electrical components in the distribution box are overloaded and burnt due to aging lines, and because the distribution box is charged and has many plastic parts, once Burning, it is easy to spread with the line, causing greater economic losses; in rainy weather, as a live device, if the distribution box is not tightly sealed or does not have waterproof function, the inside of the box is very easy to enter water, causing circuit damage. The short circuit burns out the distribution box and even causes greater losses; in the weather of lightning, due to the high vertical height of the distribution box, the distribution box may be struck by lightning; It is large and needs to be moved frequently, which may easily cause damage to the electrical appliances inside the box

[0004] At present, the safety performance of the existing outdoor distribution box is not high, and there are no specific protection measures for the internal electrical components
