Description

A safe low-voltage power distribution cabinet

technical field

The invention belongs to the field of distribution cabinets, in particular to a safe low-voltage distribution cabinet.

Background technique

The low-voltage power distribution cabinet is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen width according to the electrical wiring requirements to form a low-voltage power distribution device. The low-voltage power distribution cabinet is generally a rectangular parallelepiped. The cabinet body is equipped with instruments, control panels and displays on the front for the staff to operate or monitor. There are independent unit rooms, busbar rooms, cable rooms, etc. inside. The existing power distribution cabinet is a closed structure, and it is difficult for the operator to timely To operate, and the bearing strength is relatively weak, which reduces the overall strength of the power distribution cabinet, shortens the service life of the power distribution cabinet, and greatly reduces the reliability of the power distribution cabinet. Low-voltage power distribution cabinets are generally heavy and difficult to transport. Because the power distribution cabinets are equipped with louvers and corresponding exhaust fans on the top of the cabinet in order to reduce the temperature inside the cabinet, and there is no special dust-proof device on the top, so there will be Dust falls into the cabinet from the louvers on the top, thereby affecting the service life and normal operation of electronic components.

Moreover, a plurality of heat dissipation holes are evenly spaced on the surface of the cabinet shell, and a dust cover is integrally formed on the upper end of the inner edge of each heat dissipation hole. The protrusion forms an arc surface structure, the dust cover covers the upper end of the cooling hole, and the dust cover forms a gap with the lower end of the cooling hole.

Moreover, the gap formed by the dust cover and the cooling hole is at an angle of 45° to the horizontal.

Moreover, a plurality of pillars are evenly spaced on the upper end of the distribution cabinet, and a top cover is integrally installed on the upper ends of the plurality of pillars. The top cover is conical, and the angle between the conical surface and the horizontal plane is 5° to 15°. °, the intervals between a plurality of the pillars form an upper air vent.

Advantage and positive effect of the present invention are:

In the present invention, the cabinet shell can rotate relative to the cabinet body under the action of the cabinet slide rail, and the operator can rotate the opening of the cabinet shell to a suitable position according to the needs. , to carry out all-round operation, and can reduce the operating range, and can perform corresponding operations in a smaller range. It is also conducive to dustproof and waterproof, especially in harsh environments, which can reduce the impact of the switch cabinet door on the power distribution cabinet. The outer casing is used to protect the cabinet body from dust and water. With the heat dissipation holes and the dust cover, it can avoid large-scale entry of dust under the premise of ensuring the heat dissipation effect. The setting of the top cover has the function of dust and rain protection. The gap between them has the function of ventilation and heat dissipation through the upper vent; the small-angle conical top cover is conducive to dust prevention and drainage, and can discharge the drainage to a farther distance.

Detailed ways

The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings; the present embodiments are descriptive, not restrictive, and cannot thereby limit the protection scope of the present invention.

A safe low-voltage power distribution cabinet. The innovation of the present invention is that it includes a base 21, a power distribution cabinet 2 and a cabinet shell 1. The power distribution cabinet is installed above the base. The outside of the power distribution cabinet is covered with a cabinet shell. The cabinet The shell is cylindrical, and the side wall of the cabinet shell is formed with an opening. At least one door slide rail 12 is installed on the inner edge of the cabinet shell along the horizontal direction, and a cabinet door 11 is slidably installed in the slide rail of the cabinet body. The cabinet shell A cabinet slide rail 13 is provided below, the upper end of the cabinet slide rail is slidably installed with the cabinet shell, and the cabinet door is installed in a state where the cabinet door can slide to the opening position, and the opening position is closed; the cabinet door slides to the side of the opening position , the opening position is opened; a top cover 3 is installed on the top of the power distribution cabinet.

In this embodiment, a sealing rubber strip 14 is provided on the edge of the opening made by the cabinet shell.

In this embodiment, the cabinet door includes one or more cabinet doors, and the multiple cabinet doors are arranged longitudinally and slidably installed on the cabinet door slide rails.
