Description
TSGL transformers

Transformers three-phase dry with geafoliyevy cast isolation.

TSGL transformers are used in many branches of a national economy: are intended for transformation of electric energy in power supply networks of three-phase alternating current with a frequency of 50 Hz: are established in industrial rooms and public buildings to which increased requirements regarding fire safety are imposed, on explosion proofness, ecological purity.

Transformers three-phase dry with geafoliyevy cast isolation happen opened, actually designation TSGL, closed by the TSZGL protection cover with inputs in a casing, TSZGLF transformers to the inputs located on a flange from the face party of a casing.

TSGL transformers are intended for work in rooms, in the conditions of a temperate climate (from + 40 to - 45 degrees). Relative humidity of air of 75% at 15 ° C. Environment is inexplosive, not containing dust in the concentration reducing parameters of products in inadmissible limits. Installation height above sea level no more than 1000 m.

The magnetic conductor is made of high-quality electrotechnical steel. Special cutting and methods of assembly with application of bandages, coupling hairpins and special glues provide low losses of idling and noise level. Kremniyorganichesky paints are applied to protection against corrosion.

Windings of NN are made of an aluminum or copper foil.

Windings of VN are made both bobbin, and layered, depending on the power and tension.
The high technology of filling under deep vacuum, zapechka in electrotechnical furnaces according to the special temperature program guarantees stable quality of windings, high resistance to currents of short circuit.

Class of heat stability of windings - F, windings are painted in brown color. At observance of certain conditions TSGL transformers can quickly work at an overload without reduction of service life. The overload is limited only to an overheat of windings. The maximum excess temperature in 100ºС for a class of isolation of F is reached, only if surrounding temperature makes 40ºС and the transformer works a long time at a rated load. If surrounding temperature is lower 40ºС and (or the previous loading less than 100% of nominal), temperatures of windings will be below an admissible maximum. This temperature difference can be used for a short-term overload.

Regulation of tension to ±5% is carried out by steps of 2,5% on completely switched-off transformer (PBV) by shift of crossing points.

For protection against an overheat by request of the consumer transformers are completed with the device of the thermal protection operated by the thermistors which are built in NN windings. By request of the consumer the vibroextinguishing linings can be delivered.
