ARRANGEMENT OF OUTDOOR SWITCHGEAR APPLYING MODULAR GAS-INSULATED SWITCHGEAR



POWER TRANSFORMERS

Power transformers are designed for transforming the type of transferring electrical power voltage.

Only reliable, well-proven power transformers, produced both by foreign and Russian companies, are incorporated in the modular electric substations, produced by “Piterenergomash”.

The advantage of transformers applied at mobile modular electric substations is provided option to apply one transformer for different types of voltage: 110/35 kV, 110/20(10) kV, 110/10(6) kV, 35/10(6) kV, 10/0,4 kV.

Transferring of low voltage to another voltage type is accomplished by changing the taps of the secondary winding. At the same time, up to 100% of nominal rating power can be transmitted at tap of all types of voltage (on the customer’s request).

An option of using different types of voltage at the same mobile modular electric substation significantly expands its operating range.

PHASE-ISOLATED CURRENT LEADS WITH THE CAST INSULATION

Applying of phase-isolated current leads provides protection for electrical connections of mobile modular electric substations from mechanical shock damage, climatic factors and other external effects. The line route of the current lead consists of separate sections. Conductors of separate sections are connected applying bus-bar compensators and bolting.

Connection to air-insulated equipment is carried out applying plate-type or braided bus-bar compensators.

Bus-bar compensator performs the following functions:dampens vibration, transmitted from a transformer or a generator to current leads;

provides an option to compensate misalignment between outputs of connected equipment and current leads;

allows to correct minor deviations between the actual and the specified locations of the equipment.

DELIVERY

Modular mobile electric substations can be delivered by land road, rail or sea transport, capable of transporting 40-foot containers with an approximate weigh of 40 tons (maximum). The modules have standardized dimensions and meet all transportation standards, valid in the Russian Federation.

The compliance of container

block-modules to the transportation standard facilitates all stages of transport logistic and allows loading and unloading modules at terminals by standard equipment.

The production process of modules involves their strength testing. The container structure corresponds to parameters of packaged equipment and has an option of reinforced frames.

MOUNTING

Field mounting of mobile modular electric substation systems, produced by «Piterenergomash», made at the facility, is reduced to the absolute minimum due to full prefabrication of the modular units and prearranged mounting solutions.

Skilled specialist of «Piterenergomash» conduct a full range of works, mounting the supplied equipment and engineering systems following the requirements of the designed technical specifications, which guarantees long-term equipment operating with service maintenance.

The company carries out the commissioning, using its own resources. All works are carried out according to the approved plan and detailed design documentation. The quality control is carried out constantly, ensuring the highest level and the effectiveness of work performance.

When carrying out a complex of measures for commissioning the equipment installed in the facility made its setting, revealing inconsistencies project, the shortcomings of the equipment prior to the start of its operation, as well as check availability systems functioning.

The project was implemented in 2012, in two-month time, starting from the date of the contract signing. Total power of mobile modular electric substation supplied equipment equaled 50 MVA. Mobile modular electric substation was applied for reservation of power grid facilities during the Olympic Games in 2014.

The project was implemented in 2012 году at the facilities of “Interregional distributive grid company of Siberia”. Mobile modular electric substation is designed for operating electrical grid during the winter season, and also at the time of accident damage elimination or while the existing facilities are being reconstructed.
