6.Advantages of the substation

Dimensions and transport weight of the completely assem-bled 35 kV and 6(10) kV blocks allows to deliver them byrail, truck or by ship.

6 ABB

All individual substation blocks are designed for movingthem on their own skids.The distance between skids along the substation axis is1880 mm, and skid width is 400 mm.On the site of destination the substation can be mounted on:- special platform or concrete foundation, at the proper

level to provide protection from flood or snowdrifts(see Fig. 5 and 6),

- directly on flattened and dried land.The block unit pressure on the ground is below 5 N/cm2.The substation type ST7 is designed for operation withoutnecessary presence of the substation operating personnel.The installed (inside the blocks) automatic temperature andhumidity control systems guarantees normal operating con-ditions (Ambient temperature between 55C and +40C)for the primary and secondary circuit indoor equipment.

The substation is designed to co-operate with remote con-trol and service systems (telemechanics) in the followingscope:- performing On/Off cycles of the 35 kV and 6(10) kV

circuit-breakers,- applying interlocks to the individual automatic systems- indication of warning and emergency conditions at the

substation- indication of 35 kV and 6(10) kV circuit-breaker operating

positions- indication of improper heating operation- measurement of electrical values- fire indication system.The secondary AC and DC current devices are suppliedfrom auxiliary power transformer, and do not require anyadditional supply from secondary circuits.All protection, automatics, control, measurement and indi-cation systems are performed using different types of inte-grated microprocessor devices built into the LV panel cabi-net, depending on the electrical diagrams. Detailed descrip-tions of all the substation secondary circuits are includedwith the substation electrical diagrams.The substation provides earthing for any part of the primarycircuits with power off, using substationary earths. Simulta-neously, the substation performs earthing interlock of theparts of primary circuits with power on.Switching operations using the 35 kV switch-disconnectorincoming panel are performed outside of the block, withmanual drive fixed to the side wall of the block.Switching operation using the 35 kV and 6(10) kV couplercircuit-breaker are performed from the service corridor orby means of telemechanic systems (see substation electri-cal diagrams).The cabinets and 110 V= and 220 V, 50 Hz secondary de-vices are accessed and serviced from the substation serv-ice corridor.Insulation of secondary circuits air or solid/air.Overhead power line panels are equipped with support in-sulators and bushing insulators.Indoor outgoing panels are equipped with epoxy supportinsulators and bushing insulators.High arc protection sensitivity, internal arc detection andisolation system, and immediate pressure reduction system

make the 35 kV and 6(10) kV blocks of the ST7 substationsafe for personnel and resistant to internal arc faults.Complete factory assembling of primary and secondarycircuits reduces time of site assembly, which is limited tothe mounting of the 35 kV blocks, support structures and35 kV incoming panel equipment, dismantled before han-dling for transport. The assembly on site also requires con-nection of 35 kV and 6(10) kV block secondary circuits,connection of telemechanics concentrator (not included inthe delivery), connection of the substation to the 35 kVoverhead lines, insertion and connection of 35/6 kV powertransformer primary and secondary circuits (supplied by theclient).Design solutions, construction materials and anti-corrosioncoatings guarantee many years of reliable operation of thesubstation, even in harsh natural environments.

7. Installation of control cables between blocksInstall the designed cables and optical cables for connec-tion of block secondary circuits in a special, sealed cableduct, supplied with the substation blocks.Fix the duct to the block base. Duct length (number of seg-ments) can be determined on site; it depends on the dis-tance between blocks.

8.Protection of the substation fromatmospheric lightining discharge

Protection from atmospheric lightining discharges comingover the 35 kV overhead lines is provided by GXD51 surgearresters, installed in three phases from the side of 35 kVsubstation income see Fig. ST7-05/03-01. The GXD51surge arresters are installed on the substation block roof,and are equipped with operation counter mounted outsidethe side wall of the 35 kV block.GXD51 surge arresters and cables from the arresters to theoperation counters are isolated from the block structureusing 1 kV support insulators.Protection of the substation and the near power lines fromthe lightning discharges should be made according to thelocal regulations.

9.TransportDimensions and weights of individual 35 kV and 6 kVblocks allow them to be transported using railway, truck andwater transport means.The 35 kV and 6 kV blocks are also designed to be movedon their own skids.Skid distance is 1880 mm, skid width is 400 mm.The block unit pressure on the ground is below 5 N/cm2.Loading of the blocks onto the transport platforms is per-formed with a crane of the proper capacity, using a specialtraverse with ropes, supplied with the substation blocks2) Disassembled devices should be placed inside the serv-ice corridor or in additional wooden boxes. Detailed de-scription of all packaging can be found in PACKAGING TRANSPORTATION Instructions, found on each piece of adelivery.
