Category Of Building Structure Xxvi.2) Control And Measurement Equipment And Automation (I&C) And Internal Electrical Installation For The Intake Water In Święciechów. The Scope Includes The Construction Of: - Rm Monitoring Switchgear At The Suw Station; - Power And Control Switchgear At The Intake Of The Deep Well Pump No. Sg1; - Power And Control Switchgear At The Intake Of The Deep Well Pump No. Sg2; - Power And Control Switchgear At The Intake Of The Deep Well Pump No. Sg3; - Connection Box At The Retention Tanks;- Wireless Radio Transmission Between Facilities;- Expansion Of The Visualization And Monitoring System At The Wschowa Zuw Headquarters;- Control Installation For New Measuring Devices At The Suw Station;- Installation Of External Lighting Installations At The Intakes Of Deep-Well Pumps;- Installation Of Communication Antennas On The Premises Of The Suw Station And The Area Of ​​Deep Water Intakes. The Entire Control System Will Be Managed By A Plc Microprocessor Controller, E.G. Abb Pm564 Installed In The Designed Rm Switchgear (Detailed Description Of The Switchgear In Fig. E-Rzs) At The Water Treatment Station In Święciechowa At Ul. Water. The Plc Controller Will Control Three Deep Water Intakes Located In The Forest At Ul. Leszczyńska Towards Gołanice. The Distance Of The Water Intakes (Uw) From The Water Treatment Station (Suw) Is Approximately 1.5 Km. Communication Between Suw And Uw Facilities Will Be Carried Out By Radio Transmission. Communication Based On Radio Modems Operating In The Free, Unlicensed 433Mhz Or 868Mhz Band. For Communication, A Directional Yagi Antenna Should Be Used, E.G. Radmor 3289. For Suw, Hang The Antenna On An Existing Mast. From The Uw Side, Place The Antenna On A Lighting Pole At The Sg3 Intake. You Should Use An Antenna Cable, E.G. Type H1000, From The Antenna To The Radio Modem. Use Overvoltage Protection In The Antenna Path, E.G. Is-B50ln-C0 Type. Each Water Intake Will Be Controlled From An Individual Sg Switchgear Located Within A Given Water Intake, Drawing Pzt Akpia, Detailed Description Of The Switchboards In Point 5.4 And Drawing E-Rzs. Each Water Intake Should Be Equipped With A Deep Well Pump, E.G. Hydro-Vacuum 22Kw Type Gca.6.B4.3) Reinforcement Of The Raw Water Intake Of Wells No. 1, 2, 3 - Construction Of Deep Wells And Internal Raw Water Installations From The Existing Wells To The Node W1 Raw Water Pipeline. Scope Of Reconstruction: - Installation Of New Above-Ground Casings For Deep Wells Made Of Polyester-Glass Laminate Filled With Thermal Insulation Material; - Delivery, Assembly And Connection Of Lighting Lamps Along With Poles And Foundations; - Performance Of Electrical And Control And Instrumentation Works; - Installation Of Equipment For Deep Well Casings With Fittings And Pipelines;- Installation Of New Deep-Well Pumps, E.G. Gca.6.B4 Hydro-Vacuum, Along With Riser Pipes, Cabling And Hydrostatic Probes;- Construction Of A Raw Water Pipeline To The W1.2 Node.
