The invention relates to electrical engineering, namely, devices for the supply and distribution of electrical energy.

The purpose of the invention is to enhance operational capabilities and increase

economy.

Figure 1 shows the housing of the complete distribution device (KRU) with a partial cross-section for the case of lateral supply to the output conductors of power cables, side view; in Fig.2 and 3 section aa in Fig.1.

The switchgear contains in the housing 1 busbars 2, a hardware compartment 3. output conductors made in the form of interconnected vertical part 4 located above the busbars 2, and horizontal part 5 placed above the hardware compartment 3 and the busbars 2 perpendicularly to the front wall of the housing 1; In addition, one of the lead conductors 5 is placed on the upper, the other on the middle, the third on the lower level (Fig. 2 and 3). At the same time, the X output conductors 5 are made with external conductors - power cables 6 - along the side wall of the housing 1 in the through space 7 adjacent to it, formed by increasing the length of the busbars 2 (Fig. 2 and 3). At the same time, the width of the space 7 is selected when designing the switchgear depending on the diameter of the power cables 6 and the cross-section of the grooves of the latter. At the same size of the width of the space 7, said enlargement is performed. : e. busbar lengths 2. The specific structure of housing 1 may have several variants.

The first option, when the width of the housing 1 is equal to the length of busbars 2, is greater than the width of the hardware compartment 3 and the width of the space 7. In this case, one of the side walls of the hardware compartment 3 is simultaneously part of one of the side walls of the housing 1. Thus the space 7 is limited by the second side walls of the hardware compartment 3 and the housing 1 (figure 2).

The second option, when in the construction according to the first version the part of the side wall of the housing 1, the confining space 7 and equal to the area of the side wall of the hardware compartment 3, may not be fulfilled (Fig. 3), Space 7 can be used to connect power cables to the output conductors 5 b in the pipes.

The role of external conductors, except for power cables 6, can be performed by the side conductor. At the same time, it is supplied to the output conductors 5 perpendicular to

forged wall of housing 1, for which in said wall opposite to lead-out conductors 5 there is an opening closed by a removable cover.

For servicing the junctions of the power cables 6 and the side conductor with the lead conductors 5 in the upper wall of the housing 1 there is an opening closed on a removable cover.

For the same purpose, the upper wall of the hardware compartment 3 is made removable.

In order to service the busbars 2, the rear wall of the hardware compartment 3 is removable.

5 The device operates as follows.

It is made up of several housings 1, busbars 2 of which are interconnected in sections. In this case, in the equipment compartment 3 of the housing 1, a switching device, such as a switch, is installed, by means of which the output conductors 4 are connected to the busbars 2.

5When using the switchgear as a sectional switch, lead conductors 5 of two adjacent enclosures 1 belonging to different sections are interconnected with side conductors or power cables 6. Moreover, in one of these enclosures 1 instead of the switch, conductors are installed.

The electrical power from the power source to the busbars 2 is supplied by means of lateral supply to the lead conductors 5 of housing 1 of power cables b or side conductors. In the latter case, the side conductor is supplied to the output conductors 5 of the outermost 0 of the housing of the switchgear assembly section.

The distribution of electrical energy from the selection boards 2 to the consumer is performed by lateral supply of power cables 6 to the output conductors 5 of housing 1. 5 Thus, the expansion of operational capabilities lies in the fact that all equipment located in housing 1 is serviced from one (front) side.

50. The one-way service of the switchgear allows the installation of any enclosures 1 at the place of their placement, including a wall-mounted one, which reduces the occupied area.

55 Increased efficiency is ensured by the fact that the output of the additional conductors 4 and 5 of the housing 1 can be supplied with additional external conductors — the upper and front conductors, respectively.

These conductors can operate simultaneously with power cables 6, which expands the choice of making different grids of the main electrical circuit of the switchgear during its design.

Simultaneous operation of the front conductor with power cables 6 allows using one switchgear box of an object of the invention instead of two, three or more cases of the same connection in known switchgears for supplying or distributing high-power electrical energy.
