Description

The invention relates to electrical engineering and can be used in complete switchgears. In particular, the invention relates to the construction of a multi-functional electrical cabinet intended for use as a basic load-bearing housing in the manufacture of various electrical control or distribution devices for domestic and industrial use, for example metering and distribution panels. The above invention is intended for placement both in open areas and indoors.

Known cabinet for placing electrical equipment, comprising a housing including a rear wall, a front wall in the form of a door and side walls (SU No. 1108541, H 02 B 1/08, publ. 08/15/1984).

The disadvantage of this cabinet is that its design implies the placement of all equipment nodes in one technological space, which does not provide for limiting access to the technological space in which the equipment is located. The absence of restrictions on unauthorized access (qualified personnel and users directly) to the equipment does not ensure the safety of users due to a clear delineation of access areas.

The present invention is aimed at solving the technical problem of the implementation of the cabinet in the form of a set of separate buildings with each technological space each, access to each of which is independent.

The technical result achieved in this case is to facilitate the installation of installed equipment and its further maintenance during operation, as well as to ensure the safety of users by clearly delineating the areas of access between qualified personnel and users directly.

The specified technical result for the first embodiment is achieved by the fact that in the cabinet for placement of electrical equipment, including a rear wall, a front wall in the form of a door and side walls, a front panel is fixed on said side walls from the front door side, forming a casing with these walls internal technological space, and the rear wall and the front door are attached to one of the walls of the housing on the rotation axes located on opposite sides of this side wall, while the doors and the housing is equipped with separate locking devices.

The specified technical result for the first embodiment is achieved by the fact that the cabinet for accommodating electrical equipment, including a rear wall, a front wall in the form of a door and side walls, is equipped with at least two consecutive inner casings, each of which is formed by side walls to which on the door side, a front panel is attached for the formation of technological space inside each case, with the rear wall in series, the inner case and the front door are interconnected along the axes of rotation passing along the edges of contact of each two interconnected cabinet elements made with separate locking devices to provide selective access to technological spaces.

In addition, the front panels and / or the front door can be made with technological windows, and the rear wall is made with elements for attaching the cabinet to the bearing surface.

These features are significant and interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The invention is illustrated by specific examples, which, however, are not the only possible, but clearly demonstrate the possibility of achieving the above set of features of the required technical result.

Figure 1 - General view of the cabinet, the first embodiment;

figure 2 is the same as in figure 1, in the open position;

figure 3 - General view of the cabinet, the second embodiment;

figure 4 is the same as in figure 3, in the open position.

A multifunctional cabinet is a multivariate design consisting of a set of functional elements interconnected along the rotation axes passing along any of the contact ribs of two elements interconnected. As can be seen from figure 2, such a connection can be looped or any other, providing rotation of one element relative to another like a cabinet door relative to the cabinet wall.

Every two consecutive elements form technological spaces of various levels.

Figure 1, 2 as an example of execution presents the design of the cabinet according to the first embodiment.

The supporting element is the rear wall 1, on the outer side of which the elements 2 for attaching the wall and the cabinet as a whole to the supporting surface (for example, a wall) are installed, and the installed equipment is mounted on the inside. The back wall is a plate with various stiffeners and mounting elements for the mounted electrical equipment. If necessary, a sealing flange (not shown) is carried out around the perimeter of the inner plane of the rear wall.

Intermediate elements of the entire cabinet design are the intermediate casing 3, which play the role of protecting the installation from atmospheric and other influences, as well as from unauthorized access. Structurally, the intermediate housings are side walls closed from the front by the front panel 4 (the front panel is mounted on the side walls from the front door 5) and open from the rear, which provides technological space for the previous intermediate housing mounted on the rear wall or on the front panel electrical or other equipment. In the design of a multifunctional cabinet, one or several "intermediate housings" can be used (Figs. 3, 4, second embodiment), in the latter case, the front panel, in addition to the same panel of the last intermediate housing, is used for mounting electrical or other equipment. On the front panel of the last intermediate building, technological windows 6 (openings) are made for visual monitoring of the readings of control devices and direct access of consumers to the controls of the installed equipment.

The last structural element is the front wall in the form of a door 5 covering the front panel of the last intermediate housing. In the General case, the front panels and / or door can be made with technological windows. The door may be airtight.

As in the previous embodiment, in the example of FIGS. 3, 4, the rear wall, the inner housings and the door are connected in series along the rotation axes passing along the contact ribs of each two cabinet elements connected to each other.

Equipping individual elements of a multifunctional cabinet (intermediate cases and doors) with separate locking devices 7 allows selective access to equipment mounted in separate technological spaces.

Using this technology to build a multifunctional enclosure of electrical panels, drawers and cabinets allows you to:

- significantly facilitate the installation of installed equipment and its further maintenance during operation, especially when placing panels at a certain height when installing them on power poles, by placing this equipment on the rear wall or front panel of the intermediate casing that is open on four sides (open) ;

- eliminate unauthorized access to equipment and ensure the safety of users due to a clear delineation of access areas between qualified personnel and users directly.

The present invention is industrially applicable, as it is based on an original layout solution that does not require any other manufacturing technology other than that currently used in the manufacture of control cabinets.
