The purpose of this solution is to ensure reliable, uninterrupted, cost-effective and energy-saving power supply to the medical institution, taking into account possible extreme weather conditions, instability of external networks and needs for backup power.
According to the technical task for the design, it is planned to build a 0.38 kV overhead line from the RP-0.4 kV ZTP 348 to the GRS-0.4 kV facility located in the electrical switchboard, in the basement of the building at elevation -3,000. The project also provides for the installation of an input and metering cabinet (ShVO) on the designed support No. 3, with a rated current In=250A, mounted installation, in which it is necessary to install a pre-metering and post-metering circuit breaker, type NM8S-250S, In=250A, Ir=160A, 3P and current transformers T-0.66-0.5S, nominal 150/5.In the SHVO-0.4kV, it is planned to install internal doors with the possibility of sealing, with windows for taking meter readings, slots for controlling switching devices.The power source is the existing ZTP 348. It is planned to install in the panel No. 6 of the RP-0.4kV ZTP 348 an automatic circuit breaker of the type NM8S-250S, In=250A, Ir=180A, 3P, fororganizing selective protection of the facility's power supply system.It is planned to install and connect a reactive power compensation device UKRM-0.4-35-5-U3 in the electrical switchboard room object.The design and installation of the 0.4 kV substation is provided for in a separate project.The project provides for the laying of a wire of the AsXSn-1 brand, with a cross section of 4x95 mm2 between thedesigned supports No. 1-6. Sections of the 0.4 kV network from panel No. 6 of the RP-0.4 kV ZTP 348 to support No. 1 and the section from support No. 6 to the GRSCH-0.4 kV shall be executed with a cable of the APvBbShp-1 brand, with a cross-section of 4x95mm2, which is laid in an earthen trench in a pipe.The 0.4 kV cable from the GRSCH-0.4 kV to the UKRM of the object shall be executed with a cable of the VVGngd-1 brand, with a cross-section of 4x16mm2, which is laid according to the designed cable structures of the electrical switchboard.The plan for laying the 0.4 kV cable see drawing -EP, sheet 5. Laying and instructionsfor laying cables in the RP-0.4 kV ZTP 348 room and in the electrical switchboard room see drawing -EP, sheets 6-7.The cable is laid in the existing cable channel RP-0.4 kV ZTP 348, in a trenchand along the designed cable structures in the electrical panel facility.
