3 MODULAR TRACTION SUBSTATION Modular traction substation produced by PrJSC Pluton is an integrated solution for reliable power supply of electric transport catenary. Modular traction substation can be used as transportable or fixed electric power distribution point. Application of modern equipment and advanced solutions in the field of electrical engineering, based on years of experience, ensures safety and reliability in equipment operation. Modular traction substation refers to 17.5 kv voltage class and is designed for operation in automatic mode being an unattended installation. Modular traction substation is equipped with operating and emergency lighting, heating, ventilation, air conditioning systems, intruder alarm and fire extinguishing system. 3

4 MAIN FEATURES Safety Interlockings and protections guarantee equipment high operational safety for the staff. Environmental compatibility Pluton uses materials with minimal impact on environment in its production. The materials are recycled and safe not only during operation, but also at the end of product life. Mobility Mobility and possibility of moving to a new place of operation by road and rail. Advantages minimum of construction works on installation site; high readiness for commissioning; rapid mounting (simple connection of primary and secondary circuits); possibility to configure different circuits; antiburglar protection and disassembling; easy access to equipment; high level of operation safety; application of the most up-to-date equipment; compliance with international requirements and standards. Quality assurance Pluton Quality Management System complies with international standard ISO 9001:2008. Pluton confirmed its principles of management compliance with requirements of international occupational safety and health standard OHSAS 18001:2007 and environmental safety standard ISO 14001:2004. Operating conditions recommendations on equipment selection; designing; installation works; substation adjustment and commissioning; integrated tests; technical support; the Customer personnel training; after-sales services. 4

5 DESIGN OF MODULAR TRACTION SUBSTATION Modular traction substation can have the following design: single-unit one unified module; two-unit two unified modules; three-unit three unified modules. Manufacturing of modular traction substation for a more number of units is possible on case of necessity. Modular traction substation is a functionally finished product with organization of power and secondary circuits connections. Modules are mechanically unrelated, and are installed in accordance with the design solution. Reliable power supply is provided by modern traction equipment system, automatically controlled by SCADA system. Auxiliaries system provides operating voltage supply to all the systems. Modules have robust structure, designed for electrical installations weighing up to 22 tons in each. The modules are dust-and moistureresistant structure with IP55 protection level in accordance with IEC (except ventilation grilles in opened operation position). Substation modules are faced and lined with steel sheet with protective coating resistant to external action. Module floor, walls and roof are heat-insulated. Facing and finishing materials are fire-resistant and fireproof. All metal parts of the modules are protected against corrosion. Each module is equipped with ladders and drain. Substation is equipped with facilities for loading and unloading. Structurally, each module is divided into two compartments: transformer compartment and switchgear compartment. Equipment in modules is located according to functional groups. Each module has external devices to connect to protection earthing circuit. Operating conditions Modular traction substation operation is provided under the following climatic conditions: altitude up to 1000 m; ambient temperature operating limits: upper - plus 45 С; lower minus 40 С. 5

6 Lighting system Modular traction substation is equipped with a fixed and emergency lighting system. Lighting is provided inside and outside modular traction substation. Ventilation, air conditioning, heating systems Modular traction substation is equipped with supply and exhaust ventilation, controlled by microclimate monitoring unit. Shutters for natural ventilation are installed. The shutters can be closed with electric drive. There is also a possibility of manual control. The shutters can be additionally closed with special louvers in cold season. Ventilation grids in operating position are vermin-proofed. Air-conditioning system is provided (air cooling and heating without condensation). Outdoor air conditioner unit is installed outside on the narrow side of modular traction substation. Indoor unit is installed under switchgear compartment ceiling. Combined operation of ventilation and air conditioning systems provides a range from plus 16 C to plus 30 C air temperature inside modular traction substation. In cold season the specified air temperature range inside substation is provided by electric heating system. Intruder alarm and fire extinguishing system Modular traction substation is equipped with fire alarm system. Fire-extinguishing means are located inside. Doors and gates are equipped with door locks for the doors and gates opening from inside. Unauthorized intrusion in modular traction substation is difficult due to usage of strengthened door hinges, reliable locks, thick-walled structural elements of the module outer casing, alarm system. Doors and gates are equipped with lugs for seals. Additional equipment Power tools can be connected for assembly and repair works in modular traction substation. Modular traction substation is equipped with personal protective means and measuring instruments (on the Customer s request). 6
