Ural Company for Transformer TechnologiesThe UZTT Company is specialized in manufacturing of low-voltage and high-voltage equipment for electrical power supply systems used in industrial and civil construction, agriculture, oil and gas industries, and mining operations.

Since 2000 the UZTT transformer factory for high-voltage equipment has its own manufactur-ing of Package Transformer Substations, transformers and sells its products directly from the factory.

The UZTT manufacturing factory offers the following range of services:

• Designing of KTP substations;• Complete cycle of electrical equipment manufacturing;• Mounting of package transformer substations, electrical installation work, substations

construction and subsequent installation;• Manufacturing of oil-cooled power transformers and other components for substations;• Selling of finished electrical equipment, available and upon request.

Such a full scope of works gives our customers actual opportunity to reduce costs (both finan-cial and temporal) for project implementation as a whole, as it eliminates the need to look for different design, manufacturing and installation companies.

We constantly improve the technological process and search for non-conventional solutions which allow to adapt to changing market conditions. The company is developing new mod-el forms of transformer KTP substations, extending its product lines and equipment power range. Being targeted at market requirements, the factory manufactures 14 varieties of pack-age transformer substations with power of 25 - 2500 kVA, high voltage of 6 kV or 10 kV/ low voltage НН 0,4 kV or 0,23 kV.

All products of the factory are certified and comply with GOST and TU national standards. Prod-ucts go through stringent quality control.

Since July 2008 the UZTT plant has been an official supplier for the Ekaterinburg Electric Grid Company. We offer our regular customers different ways of work: credit on goods, deferred pay-ments, and customer-friendly system of discounts.

Being committed to the principle “the customer comes first”, the highly skilled engineers and technicians of the UZTT, LLC use a professional approach in their solutions, placing high qual-ity of customer service as a priority in their operations.

Our objective is a long-term and mutually beneficial cooperation. The distinguishing feature of our products is good value for money. This aspect is highly appreciated by our regular partners, having contributed to our today’s success and our future prospects for its amplification.

We’ll be glad to cooperate with You!

General InformationCertificate No. ROSS RU.AI50.V06884 (РОССRU.АИ50.В05884)

Function

KSO-292 series factory-assembled switchgear cells of one-sided maintenance with nominal voltage of 6 and 10 kV, 50 Hz three-phase DC are designed for grid switching equipment with insulated-neutral conductor or neutral conductor,grounded via arc blowout.

Structure of KSO cells identification

Structure of main circuit identification(the given identifications are used in diagram tables – pp. 4-12)

Х – index number of main circuit diagram;

X – letter identification:

Pо – PPO-10spring drive; E – PE-11 electromagnetic drive; EV – VVTE-M 10 vacuum switch with in-built electromagnetic drive.

A – automatic switching;

X – nominal cell power, A (400, 600, 1000, 1600);

X – letter identification:

TSN – three-phase power transformer (25 or 40 kVA); TN – voltage transformer; RVO, RVR – charge neutralizer type; OPN – voltage suppressor.

Operating conditions:• Altitude above the sea level – not more than 1000 m;

• Lower ambient air temperature limit: - 25 C;

• Higher effective value ambient air temperature 35 C;

• Non-explosive environment, containing no current-conducting dust, aggressive gases and vapors, depleting metal parts and insulation.

DesignKSO-292 series cells are basically a complete analog of KSO-285 cells both in power diagrams and in secondary diagrams. In comparison with KSO-286 cells, the KSO-292 cells have the cur-rent transformer module (TOL-10) moved from the back wall to the front wall. Other external and connecting dimensions are similar.

KSO cells are implemented as welded metal structures made of folded steel sections. Inside the cell the main function equipment is placed. Switch and disconnector drives and auxiliary equipment are located on the front side.

Access inside the cell is provided via two doors: upper door – to power-switch zone, voltage transformer and fuse, lower door – to cable connections zone, power transformer and charge neutralizers. The lower door has an inspection window for viewing the inner part without re-moval of voltage. The upper door serves as a panel, on which the auxiliary circuit equipment is mounted. The cables are protected against high voltage by a removable steel sheet with an in-spection window.

On the front side of the center cell section the connecting terminal panel is located, serving as a channel for backbone buses of operating power circuits of switching-on electromagnets, con-trol and signal circuits, for performing inter-cell secondary connections when mounting KSO cells.

Markings of circuits, connected to the terminals, are given in electric essentials, supplied by the company on client’s request.

KSO cell design allows assembling of all the cells into a switchgear row and connection of main circuits with bus bars. Connection with linear buses is possible between cells, compris-ing blocks. According to main block circuit diagram, connection with linear buses is performed for neighboring cells within a single row.

If two-row cell positioning is used, bus bridges with or without disconnectors are used for con-necting main circuits with bus bars. Bus bars, bus and sectional KSO cell disconnectors are equipped with enclosing grilles on the front side.

The following blockings are present in the KSO cells:

• Blocking, preventing switching on and switching off of linear and bus disconnectors with energized high-voltage switch or load-break switch;

• Blocking, preventing enabling of the earthing blades with enabled operating disconnec-tor blades ;

• Blocking, preventing enabling of the disconnectors with enabled earthing blades.

In technically justified cases, on request, electromagnetic blocking devices are installed in the KSO cells on the earthing blade drives. Electromagnetic locks are installed on the earthing blade drives of bus bars regardless of request.

Bulb socket for interior lighting is installed inside each cell. Drive-earthing blade handles are colored red. Earthing blades, earthing blade drives and earthing buses are colored black. Drives of main and earthingdisconnectors are equipped with devices, allowing them to be locked in enabled or disabled position by padlocks.

KSO cell body allows welding it directly to earthed metal structures. Earthing clamp for con-nection of elements, needing temporary earthing, to the cell body is located on the front side of the cell.
