Description

Purpose:
Purpose floor boards is the reception and distribution of electricity in three-phase four-wire and five-wire networks with a voltage of 380/220V and a frequency of 50Hz with a grounded neutral. The functions of the power distribution board are also to perform infrequent switching on and off of power lines of group circuits, and to protect consumer lines from excessive overloads and short circuits.
Through application floor panels it is possible to solve the following problems: receiving electricity with a voltage of 220/380V; apartment distribution and metering of consumed electricity; protection of group consumption lines of apartments during overloads and short circuits; protecting people from electric shock; placement of telephone, television, radio equipment and other low-current networks.

Area and conditions of application:
Floor boards ShchE can be used to provide power to two, three or four apartments, for lighting and power plants public, residential, industrial and administrative, buildings and structures, etc.
The device is intended for use in the following conditions:
Climatic modification UHL, placement category 4 according to GOST 15150-69, altitude 2000 m above sea level, temperature environment from +5°С to +40°С at relative humidity no more than 60% at a temperature of +20°C.
The environment is not explosive and does not contain aggressive vapors and gases in concentrations that destroy metals and insulation, and is not saturated with conductive dust.

Design:
Floor boards ShchE can be manufactured in built-in and wall-mounted versions, and installed permanently in niches on floor platforms.
ShchE building is a welded metal structure, divided by a partition into three compartments (metering, distribution and low-current), in which equipment is installed in accordance with the purpose of the compartments. The metering department is intended for the installation of single-phase or three-phase meters. The distribution panel of the ShchE provides for the placement of automatic switches and devices protective shutdown(RCD). Doors installed on the facade provide access to the distribution board compartments. The metering compartment door is equipped with windows for monitoring meter readings, which are covered with transparent material.
In order to facilitate the installation of equipment and equipment and save time, the mounting panel is removable.
Manufacturing of ShchE shields immediately with installed tires riser, makes it possible to accurately calculate the number of wires required to carry out work on wiring lines inside the switchboard. Thus, it is possible to make a shield before installing it on site, even in the absence of information about the cross-section of the riser wire.
Features and Benefits
S.H.E. Shield Structurally, it is a housing built into a niche, consisting of three compartments:
. Input-accounting - provides the ability to place up to 4 meters, space for installation is provided circuit breaker, performing the function of disconnecting the main line;
. Distribution compartment - in this compartment it is structurally possible to install up to 9 automation modules for each apartment; inside the compartment, access to all live parts is closed by a removable false panel;
. Low-current compartment - provides the ability to lay a radio network, television network, telephone line and line security and fire alarm system, intercom network, install connection boxes for each of the networks.
. All compartments are designed with doors with a lock with two keys with the same degree of security. The panels are equipped with spacer bolts for installation in a niche.
. Powder coating, color RAL 7035.
Floor boards ShchE in accordance with the customer’s wishes can be manufactured to ensure the possibility of servicing a strictly defined number of apartments.

Electrical diagrams for switchboards are provided by the customer and may vary depending on the project.

LLC "SpetsNKUServis" produces floor boards and supplies them in a form completely ready for installation. Thanks to the use quality components And great experience Our employees' equipment works for a long time and without failures.

Such installations are used in residential apartment buildings, in private cottages, country houses etc. Floor switchboards perform several key functions of power supply at once:

• energy reception and distribution;
• protection of group and distribution lines from overloads and short circuits;
• protection of people and personnel from electric shock;
• accounting of consumed electricity.

Floor panels according to GOST R 51321.1-2000

SpetsNKUServis LLC manufactures them in accordance with national standards. Products are intended for installation on staircases and can be designed for two, three or four apartments. The design of the shields consists of several compartments:

• subscriber It contains equipment to protect lines and inputs;
• accounting compartment. It contains a device for disconnecting the stair riser and counters;
• low current. Devices for television, radio broadcasting and telephone networks are located here.

Floor panels are manufactured according to individual drawings. Depending on the installation method, they are mounted on the wall or built into a special niche. The removable mounting panel makes installation much quicker and easier.

The complete set and version of the floor panels are negotiated with each customer separately. Upon completion of assembly, mandatory quality control is carried out. Guarantee provided.

There are two main series of floor panels - the floor switchboard ShchE and the UERM device (floor distribution device, multi-box).

Floor distribution boards (SDBs)

ShchE floor board is intended for reception, accounting and distribution electrical energy. Panels are used in residential, social and small office premises. Voltage work network- 220 volts (50 Hz). Also, the electrical floor panel serves as line protection in case of overloads and short circuits.

The degree of protection of the products corresponds to IP21 (according to GOST 14254-96).

Operation of electrical floor boards of the ShchE series is allowed at an altitude above sea level of no more than 2 km, only at temperatures from minus 5 to plus 40 degrees Celsius. It is not allowed to operate products in explosive environments, as well as in environments containing steam or aggressive gases that can destroy plastic, metals, and insulation.

The floor accounting and distribution board is logically divided into 3 compartments:

Subscriber compartment. This compartment contains devices for protecting input and output lines.
Accounting compartment. This compartment contains an automatic device for disconnecting the stair riser and single-phase meters electricity.
Low-current wiring compartment. This compartment contains devices for the television network and data transmission networks (computer, telephone, radio broadcasting).
The housing for the floor switchboard is made in a niche version, since entry into the switchboard is made without cutting the 380 V main.

UERM - floor distribution board

The UERM switchgear is intended for:

• for accounting and distribution of electrical energy,
• protection of lines from overloads and currents short circuit in networks with solidly grounded three-phase neutral AC voltage 380/220V, frequency 50Hz,
• protection against electric shock from accidental contact with conductive parts of switchboard equipment,
• preventing fires from electric current caused by ignition of wire insulation due to excessively high leakage currents to ground.

The devices can be used to accommodate telephone, radio broadcasting and television networks and are designed for laying riser wires with a cross-section of up to 95 mm2. The UERM panel can be manufactured for use with systems grounding TN-S, TN-C, TN-C-S according to GOST 30331/2 GOST 50571.2

The degree of protection of the boards corresponds to IP21 (according to GOST 14254-96).

Operation of electrical floor boards of the UERM series is allowed at an altitude above sea level of no more than 2 km, only at temperatures from minus 5 to plus 40 degrees Celsius. It is not allowed to operate floor boards in explosive environments, as well as in environments containing steam or aggressive gases that can destroy plastic, metals, and insulation.

The UERM panel structurally consists of two vertical boxes on a frame and a set of modular boxes that house power and low-current equipment. The boxes are the connecting elements of the entire frame. Unit height and drawer layout may vary depending on terms of reference project (discussed with each customer individually).
