Complete transformer substation kiosk type tightly from 25 to 1000 kVA

Complete transformer the kiosk type substation for outdoor installation for cable and overhead networks next, tightly, designed to receive, transit, transformation and distribution electric energy of three-phase AC voltage of 6-10/0.4 kV frequency of 50 Hz. Design tightly made in the form of commodity metal container, divided into three cover:

· distribution the high-voltage compartment low voltage switchgears);

· transformer compartment;

· distribution device low-voltage compartment low voltage switchgear).

Tightly with air input on the high-voltage side are divided into:

· c disconnector in compartment low voltage switchgears,

· with direct input.

In tightly with direct input constructive role disconnector High voltage switchgear performs RLND (not supplied) that are installed on the support.

Tightly on the number of used power transformers are divided into:

· mono-transformers,

· two transformers.

Case, all components and parts tightly covered with a corrosion-resistant primer and paint in color colours:

· door-RAL order.

· body and roof - RAL 5005.

Possible staining tightly in corporate colours customer.

Work tightly considered under the scheme of main circuits and electric concept. The voltage of the transmission line is fed through load switch or disconnector and high-voltage fuses at the inputs the power transformer. Reduced to 0.4 kV voltage through introductory switching devices is fed to the power feeders and feeder street lighting.

Tightly in dependency type has the following protection:

On the side high voltage:

· from atmospheric overvoltage;

· from multiphase short circuits;

On the side low voltage:

· single-phase and multi-phase short circuit power feeder;

· from short circuits feeder street lighting, circuits interior lighting substation;

· from atmospheric overvoltage.

Equipment protection against atmospheric overvoltages is high-voltage and low-voltage arresters. Protection of power the multiphase transformer from short circuits is provided the fuse protection of the outgoing feeders from short circuits is circuit breakers / breakers with built-in combo breakers or fuses.

Control of current and voltage is ammeters and voltmeter with selector switch.

Attach tightly to the air lines 6-10 kV through the switch, which is installed separately on end supports 6-10 kV overhead lines (not supplied).

High-voltage line 6 (10) kV to HVSG joins through high-voltage bushing mounted on the roof (air entry) or through the hole in the base station (cable entry).

High voltage air entry is made in a separate structure and has a flange connection with ktpnu data. On the HV input is set:

· dischargers 6 (10) kV type RVO or ARF;

· bushings ICS-10-630 via a cellular rubber seal;

·
