Transformer substations:

Transformer substations of modular are devices that are installed indoors. Functional tasks:

accept electrical energy of 3-phase alternating current (frequency 50 Hz), with a rated voltage of 6 (10) kV;
convert to electricity with a voltage of 0.4 kV;
distribute to consumers.

The transformer substation consists of:

high-voltage input cabinet (input voltage 6(10) kV) with a disconnector or switch – SF6, vacuum;
power transformer;
switchgear РУНН.

The design of the distribution block includes three cabinets – low voltage input, sectional and outgoing lines. Cabinets are equipped with withdrawable circuit breakers of domestic and foreign production.
