Metal PTS

Kiosk-type metal-enclosed packaged transformer substations (Metal PTS) for voltage of 6 (10)/0,4 kV, with capacity from 25 kWA to 1,600∙ kWA, are used to supply power to the industrial enterprises, enterprises of extractive industries, and infrastructure sites.

Features

• Small size.

• Fully prefabricated.

• Quick installation and commissioning.

• Can be moved using any type of transport.

• Substations are equipped with the equipment of own manufacture.

• Made using high quality materials and components.

• Use of special painting process that prevents corrosion.

• Doors and gates of substation have rubber seals.

• Possible customization to fit non-standard layouts.

• Can be painted with the customer's distinctive corporate colors.

 

Design

Metal PTS is a welded kiosk-type structure. Usually metal PTS has three compartments: HV input compartment (HV switchgear), where high-voltage switching and protection devices are installed; power transformer compartment; LV compartment (LV switchgear), where the equipment for 0.4 kV lines is installed.

HV KSO-366 and KSO-314UM series cells can be installed in  the HV compartment:

- on incoming/outgoing lines: gas-blast circuit breakers (VNA) or vacuum circuit breakers (VNVR), interrupters (RVZ);

- for power transformer protection: fuses combined with vacuum circuit breakers or interrupters.

HV switchgear compartment connections are made via  switchboards SchO-70 and cabinets ShNN-GRSch:

- on entry: circuit breakers of withdrawable/plug-in/fixed modifications, load break switches, disconnectors;

- for outgoing line protection: throw switches with fuses or circuit breakers of plug-in/withdrawable/fixed modification;

- for partitioning - circuit beakers of plug-in/withdrawable/fixed modification, load break switches, disconnectors.

High voltage 6-10 kV input can be fed by underground/overhead lines. Outputs for outgoing LV lines can be underground or underground/overhead.

To create normal conditions for operation of electrical equipment metal PTS can be equipped with heating devices.

If necessary, metal PTS is additionally equipped with fire alarm and access control systems.

On request metal PTS can be bundled with service platforms and stairs.
