Installation of substations

Description

The company manufactures installation of transformer substations.

Consider a sequence in which the mounting is performed complete transformer substations 35/10 kV equipped switchgear outdoor type KRUN-10.

The composition of such substations includes the following elements prefabricated: prefabricated 35 kV, complete 10 kV, consisting of cells KRUN-10 K-HS, mounting brackets from the supporting insulators for input from a transformer to a metal-clad switchgear cabinet, the internal elements and outdoor substation fences. Prior to installation should be planned site for all the substations, installed foundations or reinforced concrete pillar, prepared trenches for laying of power, control cables and the grounding circuit. If simultaneously with the preparation of the site is being built substation fence, then it removable openings for delivery of equipment and materials must be provided. Completeness of the equipment supplied for the installation must be welded under the sheet delivering plant.

Installation of transformer substations, is reduced to the assembly of metal portal of 35 kV, installation, crane or other devices. After the installation is mounted on a portal necessary high voltage equipment (circuit breakers, fuses, etc.) And the suspension insulator strings for flexible wires busbar opening portion. At the same time establish the support columns under the dischargers, disconnectors, current and voltage transformers (if provided by the project), as well as lightning rods. After installing the apparatus on a portal and the reference stacks controlled linear disconnectors and operate the entire bus-bar opening portion including slopes for high voltage apparatuses. Flexible wire bus is connected with special piercing connectors. At the end of the installation check the tightness of all bolted connections.

At the end of the installation to begin carrying out commissioning works, which are carried out by specialized teams. All installation work, adjustment of the transformer and the secondary switching circuits corresponding certificates are issued and protocols. This documentation together with the technical documentation and instructions of manufacturers of complete equipment will be passed by the operating organization.

Complete transformer substations equipped with transformers consumers of low power (250-630 kVA), so they can be delivered to the installation site by motor vehicles fully assembled.
