Complete two-transformer substation kiosk

CTP Booth - complete two-transformer substation outer installation

three-phase alternating current with frequency 50 Hz is a

electrical device designed to receive, conversion

(by voltage level by means of power transformers, transmission

and distribution of electric energy.

Used in power networks:

industrial enterprises

rural and urban settlements

construction sites and other facilities

Two-transformer substation CTP kiosk type there are two standard versions:

- dead-end

- throughs

Two-transformer substation CTP kiosk type under the terms of the security services are divided into:

- with switchgear with single row the location of the cells without bus bridge

- switchgear with double row location of cells with bus bridge

The number of power transformers two

Constructive performance

CTP Kiosk type represents modular prefabricated welded metal structure. Blocks (modules) made with a frame made of steel profiles with resistant coating that provides increased corrosion resistance and modern design. Modules covered galvanized sheet thickness 1,5 mm

Blocks (modules) KTP Kiosk type , as are:

- switchgear high voltage HVSG-6(10) kV with cell type CSR

- Bay power transformer,

- switchgear low voltage Low voltage switchgear-0,4 kV with the cell type THAT.

Layout KTP Kiosk type, its dimensions and the number of blocks depends on the schema the electrical connections and the number of cells and transformers. Blocks KTP Kiosk type split metal partitions, and have separate doors, lockable locks.

For ventilation and cooling installed inside block devices doors have openings with shutters. In some cases, Luggage the transformer can be provided with an axial exhaust fan..

In high voltage switchgear and low voltage switchgear substation cells are arranged in one a number of education service corridor. Modules KTP Booth type are equipped with lighting, heating and ventilation finished wiring that allows the installation of a substation in a more short period of time.

High-voltage input, the order is air, with installation on the roof of the compartment of the bushings with ARF or cable through the floor or wall. Low-voltage outputs can be cable or air, with ustanovkoi rooftop KTP Kiosk type frame with insulators for overhead lines-0,4 kV.

The basis KTP Kiosk type is monocoque design of the profiles, which has a solid or expanded metal flooring with malopriemlem hole emergency release of oil from the transformer and holes for input and output cables. The strength of the base transformer module is designed for installation one power transformers up to 2500 kVA.

HVSG on CTP capacity of over 250 kVA runs on the base camera series KCO-HH, and over 1,000 kVA can be made on the basis of CSR-2xx with vacuum circuit breakers.

Low voltage switchgear, with panels SHCHO-70 as circuit breakers on the input and exhaust lines and breakers and fuses.

In low voltage switchgear can be provided with the opportunity installation:

- metering;

- automatic or local government street lighting;

- circuit breakers for their own needs (lighting, heating and ventilation).

Join KTP Kiosk type to the air line VL-6(10) kV, typically through a three-pole linear disconnector type RLND-10 or similar to him.

As power transformers are used transformers with dry and oil the main insulation of the windings.

Before sending all the modules are laid all inter-module communication is marking and comprehensive testing the electrical equipment.

On the order in KTP Booth type can be performed: electric; electric heating; natural or forced ventilation; split-system air-conditioning and fire the alarm system. T./F. 4922-305368 ;8-903-6471471
