Description

Modular floor distribution device.

Modular floor distribution device (UERM) belongs to the field of electrical engineering related to the production of floor distribution boards for residential and public buildings and is intended for: reception, distribution and metering of electricity with voltage of 220V and 380V, to protect lines during overloads and short circuits in three-phase networks with voltage 380V and 220V frequency up to 60 Hz with a grounded neutral, to protect against electric shock when accidentally touching live parts or non-live parts I okazavschimsya energized, to prevent the occurrence of fires caused by the ignition conductors due to excessive leakage currents bolschoy to the ground, to accommodate the communications apparatus, alarm and automated power metering system (ASUE). Known flap lighting floor (patent of the Russian Federation No. 2121202, Н02 В1 / 03, 1998) containing series-connected devices for the visible breaking of the electric current and voltage circuits and a three-pole switch located in the frame, which is divided by partitions into compartments.

Н02В 1/03

Known device floor distribution sectional (UERS) (certificate of the Russian Federation No. 17241, Н02 В1 / 03, 2001) containing a frame, partitions, fasteners and divided into compartments, with electrical equipment for protecting power circuits, metering and distribution of electricity, locked doors mounted on hinges and equipped with locking devices, the compartments being made in the form of separate electrical panels mounted on a frame between and on the sides of at least two vertical power boxes, nnyh on the frame and separated by length into several parts, in which the power electrical circuit laid.

The purpose of this model is to improve the technical and economic characteristics of the device, increase its reliability, service safety, fire safety, durability, as well as improve its ergonomic performance.

This is achieved by the fact that two boxes (communication box, signaling box and electrical box) together with jumpers form a frame on which the modules are mounted. The communication and signaling box contains communication, signaling, radio, television and networks of an automated energy metering system (ASUE). At the bottom of the box is provided

a place for the installation of a cable branching coupling for the installation of urban telephone cables. In the electrical box, there are laid lines supplying at least one apartment, lines for working and evacuation lighting of corridors and elevator halls, as well as network groups for powering harvesting machines.

Boxes are the connecting elements of the entire device, at least two modules are attached to them and the frame, which are boxes equipped with various equipment.

Boxes (modules) are divided into accounting and distribution and boxes for placement of devices of television, telephone and radio transmission networks, as well as dispatching equipment and an automated energy metering system (ASUE). All drawers are closed with doors with locking devices.

An example of such a product is a Modular Floor Distribution Unit (UERM) for four apartments, shown in FIG. 1. UERM contains: two boxes (low-current (1) and electrical (2)) interconnected by jumpers (3) with eight modules mounted on them. In accounting boxes (modules) (4) is installed

following equipment:

A) for single-phase input:

-A device that allows you to disconnect the box from the riser of the supply line of the apartments;

- electric energy meter;

- protective shutdown device (RCD) with overcurrent protection;

-automatic switches for protecting group lines of an apartment.

C) with three-phase input:

-A device that allows you to disconnect the box from the riser of the supply line of the apartments;

-meters of electric energy;

- protective shutdown device (RCD) with overcurrent protection.

The disconnecting device is installed inside the box in a protective casing, which has a device for sealing it. In even - distribution boxes are installed to the right and left of the electrical box according to the number of apartments on the floor.

communication and signaling facilities. These modules are installed on a low-current box. They are mounted: television equipment (5) in the upper cell, then telephone network devices (6), then a radio and intercom (7) and in the lower cell - equipment of an automated energy consumption metering system (ASUE) (8). All boxes are locked with lock doors (9).

Installation of boxes and modules is possible with different options, depending on the type of building (residential, public, office).

In the electrical box (2), the following networks are installed:

-group networks of apartments;

-nourishing network of apartments;

-working lighting of corridors and elevator halls;

-Evacuation lighting of corridors and elevator halls.

In the middle part of the box, a bus is welded to the structure, which has contact clamps for connecting protective conductors (PE). Insulated buses are also installed here, according to the number of apartments, each of them has contact clamps for connecting zero working conductors (N) for the outlet network and the lighting network.

: D) N

are laid in a specially welded U-shaped profile. Networks of emergency lighting of corridors and elevator halls are laid parallel to the networks of working lighting from the outside of the U - shaped profile. Each network of wires laid in an electrical box along its cable and is attached to the box elements with special clamps or brackets.

The wires of the communication and signaling networks laid in the communication and signaling box are spaced apart and fixed, and the telephone network wire is laid in a special profile, which makes it difficult for unauthorized persons to access this network.

In the electrical box there is a transverse passage for laying the ASUE cable in apartment boxes located on the opposite side of the box.

In the upper part of the boxes, passageways are provided for the exit of group apartment networks and communication and signaling networks.

To prevent the spread of fire through the floors, both boxes of the device have partitions installed in the upper part (end) of the box close to the opening of the floor

buildings that, after laying all electric networks, are closed up in building conditions with easily penetrable fireproof material. In this case, the partition serves as a structure supporting this material.

Laying cables and wires of communication and signaling in boxes closed by covers, placing electrical equipment and communication systems and signaling in boxes closing with lock doors improves design, increases reliability and fire safety of the device, protects residents and maintenance personnel from electric shock, as well as provides convenience in operation.
