This invention relates to electrical engineering, in particular to switchgear cabinets.

The aim of the invention is to simplify the design and reduce the cost of the switchgear cabinet.

FIG. 1 shows the cabinet of the complete switchgear with the rear rear lid and the upper partition between the compartments of the modular and linear busbars, side view; in fig. 2 - the same, rear view.

The switchgear cabinet contains a housing 1 divided by partitions into compartments of the withdrawable element 2, busbar 3, linear busbar 4, relay equipment 5. Busbar is made of phase-mounted horizontally assembled 6 and linear 7 buses with rigidly fixed vertical busbars 8 which, in the place of attachment to horizontally mounted tires, are fastened on one shelf of an additional element of predominantly V-shaped section 9, each of which is different with its own shelf 3 clipped to the insulating support 10. The insulating support 10 fixed to the cabinet and the vertical partitions are offset from each other horizontally and vertically.

insulators 12, mounted on a vertical partition 13 between the compartments of busbars 3 and element 2, the vertical taps of busbars 6 in the middle part are made with a bend in the direction of the compartment of the withdrawable element 2, and the partition 13 is also made with a corresponding bend. With the same dimensions, the invention makes it possible to refuse to use in the device composite multilayer partitions between its functional compartments,. which simplifies the design, reduces the consumption of sheet insulation materials. 2 Il.

Vertical taps 8 from horizontal busbars 6 with its lower part are fixed on fixed plug-in contacts 11 of the clamped element 2, mounted in bushing insulators 12, mounted on the vertical partition 13 between the busbar compartment 3 and clamp element 2 and vertical tapping of busbars 6 in the middle part are bent toward the draw-out element 2, the partition 13 is also made with the corresponding 1m bend 15

Vertical taps 8 line tires 7 in the lower part are fixed on current transformers 14.

20 The invention makes it possible, with the same dimensions, to refrain from using composite multi-layer partitions between its functional compartments in a small cabinet of a switchgear switchgear, which greatly simplifies the design of the cabinet, reduces the consumption of sheet insulation materials, and increases manufacturability.

30 In addition, the installation and disassembly of the current-carrying circuit in cabinets is simplified and, thus, the labor costs associated with the manufacture, installation, repair and maintenance work of the switchgear cabinet are reduced.
