LOW VOLTAGE SWITCHGEARS KEY FEATURES

MODULAR DESIGN

The cabinet design provides for the installation of a full set of electrical and other equipment, controls, protection and field devices in accordance with the customer’s requirements, and ensures access to devices and terminals during installation, wiring, maintenance, and repair.

USG cabinets of one maintenance type (unilateral or bilateral) can be connected into multi-cabinet structures - switchboards (assemblies, sections).

The design provides for bus-bar jumpers (bus ducts) to connect individual parts of a switchboard (assembly, section) located at a distance from each other.

PURPOSE

USG is a series of low voltage modular design switchgears operated in power plant auxiliaries and used for power supply, sectioning and distribution as well as controlling electric drives for various actuators (for example, controlling isolation valves, ventilation valves, pumps, etc.).

USG (Ural Switchgear) are an advanced series of low voltage switchgear cabinets manufactured by FSUE UEMZ, modernized in accordance with international standards and manufactured in seismic protection in accordance with IEC 60980.

A WIDE RANGE OF ELECTRICAL CIRCUITS

As a rule, USG are built on a system of standard functional units and solutions, but it is possible to manufacture cabinets according to non-standard schemes for the main and auxiliary circuits, including the use of non-standard functional units according to the customer’s concepts.

HIGH RELIABILITY AND LONG SERVICE LIFE

USG are manufactured using unified load-bearing structures and shells.

The cabinets’ design provides the necessary rigidity, shock resistance, and resistance to external effects.

The average time between failures is no less than 250,000 hours per unit, provided that the number of cycles of switching devices does not exceed the permissible values for them;

The аverage service life is 50 years.

KEY FEATURES KEY FEATURES

ENHANCED PROTECTION OF ELECTRICAL EQUIPMENT

USG cabinets provide all the necessary types of electrical equipment protection: protection against short circuits, overload protection, earth fault protection, protection of minimum voltage, automatic load transfer arrangement (if possible), protection against open-phase modes, and other types of protection in accordance with the applicable schemes.

Input cabinets provide the possibility of installing additional relays ensuring disconnection of the input switch for backup protection against three-phase short circuits for outgoing connections and failure of their switches.

POSSIBILITY OF INSTALLING ADDITIONAL AUTOMATION AND DIAGNOSTICS MODULES IN CABINETS

USG cabinets are intended for joint operation with microprocessor automation tools to perform I&C and diagnostic functions.

For a distributed I&C system, USG cabinets may include RTU and upper level communication modules operating via optical or wired interface (up to 15 modules).

Cabinets with a built-in diagnostic system of motor operated valves can be used to acquire diagnostic data and monitor the state of controlled electric devices.

COMPACT

Due to a wide range of cabinet dimensions the most optimal use of space is ensured, thereby reducing the number of cabinets.

RESISTANCE TO ENVIRONMENTAL IMPACT

The degree of protection ensured by a cabinet casing is IP31 by default. Upon special order, cabinets can be manufactured with a IP41 or IP54 degree of protection.

USG cabinets are resistant to corrosive agents in the environment corresponding to a Type II or III atmosphere.

Internal mounting elements and fasteners are made of corrosion-resistant materials or have a protective coating.
