Pole package transformer substation

no-image

Application and designated area

Pole-top package transformer substations with poles (hereafter — PPTS) are intended to receive three-phase alternating current with LV of 6-10 kV, transform it and distribute over three-phase four-cable network with a grounded neutral at voltage of 0.4 kV (LV) to power supply country town consumers. Pole-top substation specifications are specified in the following table.

Structure of reference designation

PPTS — ХХХ / 10 (6) / 0.4 — U1, version 1-6;
PPTS is letter designation (pole-top package transformer substation);
XXX — number which determines power of substation in kVA;
10, (6) — rated voltage on high voltage side (HV-10;6 kV);
0.4 — rated voltage on lower voltage side (LV-0.4 kV);
U1 — climatic and position category complies with GOST 15150-69;
* Hardware version is chosen from the table.

 

Versions of package transformer substations

Design

Pole-top transformer substation is installed on two construction metal legs OL 10kV interconnected with metal constructions with substation equipment: power transformer, 10 kV fuses, RVO arresters, low voltage switchgear (LVSG RUNN) and crossarms which connect OL 0.4 kV. Substation connection to the network is made by means of breaker QS1 of HVBO installed on leg OL-10 (6) kV.

Schematic circuit diagram

Scheme 2 describes power transformer connected to a 10 kV line by means of breaker and fuses.
Side of transformer substation of 0.4 kV with grounded low voltage transformer winding is connected to power lines and street lighting line (Customer’s option).
Circuits of lines 0.4 kV are equipped with:
• automatic breakers with surge and short circuit protection;
• switches with protection of outgoing lines with fuses of type PN 2.

Power account is performed with a three-phase counter switching via current transformers.
Circuits of street lighting line are equipped with starting switches controlled by photoelectric relays.

Application and designated areas

Package transformer substations for urban networks (KTPGS) are intended to receive three-phase alternating current with HV of 6-10 kV, perform its transformation and distribution over three-phase four-cable network with a grounded neutral at voltage of 0.4 kV. The substations are applied to power supply consumers in urban electric networks.

Package transformer substations for urban networks KTPGS is defined by the table below.
KTPGS is delivered in a metal casing with configuration in the figure, (2KTPGS in two casings) with mounted power transformers, cabinets on HV side and DM side, street lighting cabinet, account unit (counters unit) and replace substations assembled on-site from separate KSO cabinets, EP 90 panels and other products.
HVLG are equipped with two load breakers of VNA (VNR) type with hand actuator, one breaker RVZ (for substations with transformer of power 250, 400 and 630 kVA, three load breakers are installed).
LV cabinets are equipped with switches and have power counting system.
In case of two installed substations, a separate casing is installed. It is represented in the figure and has two KSO 393 cabinets and scheme and is manufactured according to TU U specifications.
If you want to order substations, please fill in the data sheet.
