Electrical equipment 9 storey 216 apartment building.

The power supply of the 9-storey 216-apartment building is performed according to the Design Assignment, - Architectural, construction and sanitary-technical parts of the project. In accordance with the existing norms and rules in the territory of the Republic of Kazakhstan. Tension on input ~ 380/220 Rated power is 348.3 kW Category of power supply III. Power supply of a house it is provided from 2 introduction distributing devices 1VRU and 2VRU. Input and distribution devices (VRU) are accepted as VR1 with automatic lighting control unit (BAUO) of l.p. platforms and entrances to the residential building. VRU are located in the electrical panel room located in the technical subpole. A power meter of common house consumers, circuit breakers of the lighting network of staircases (hp) and technical subpoles are installed on the BRU. Mounted on staircases are superimposed boards of SHE type of hinged type. Diff inlet device is arranged in boards. protection, apartment metering counters, group line circuit breakers. Supply lines from VRU are laid underground open in vinyl plastic pipes by PV-1 wire. The branch from the horizontal route to the risers is made through the branch boxes. Vertical laying of supply lines and lighting networks are carried out along walls and in the floor of the next floor. The group network in the apartment is made three-wire (phase-L, zero working-N and zero protective-PE conductors), wire with copper residential grade PPV-3x1.5 mm2/and PPV-1-3x2.5mm2/in the floor of the next floor, in the plaster layer of the walls. Each apartment includes trigroups (two groups of 16A, and one 10A). In each apartment the electric call on 220B is established, the electrical wiring to a call is carried out by a wire of PPV-1-3h1.5. Control lighting of technical equipment is provided by hermetic switches. installed on the sites of those floors. Lighting of l.k. sites is provided with lamps with motion sensors, lighting of the facade of the veins. houses - Keremet model LED lamps located at a height of 5 m. At the entrances to the entrances, lamps with LED lamps are installed. The photosensor is installed on the 2nd floor on the inside of the outer frame of the window and is shielded from direct sunlight and foreign light sources. Control of the technical sub-floor lighting is provided by individual hermetic switches. The light source is LED lamps. Local lighting control, switches installed at elevation up to 1 m on the door handle side. Group networks run; STP wire is hidden under plaster. All metal parts of the equipment, normally non-energized, but which may be under it in case of insulation failure, must be connected to the protective (PE). In turn, a protective zero wire of the network is connected, at the input to the building, a potential equalization system is performed, which includes: - protective grounding device made of strip steel 40x4mm, which is connected to the protective grounding terminal of the lead-in device, to which, the internal grounding circuit is connected to the external grounding device made of steel angles 50x50x5mm with a length of 2.5m, clogged into the soil to a depth of 0.7m and connected to each other by steel strip 40x4mm. Lightning protection on the roof of a residential building is a lightning screen made of round steel ∅6mm with a pitch of 6x6m. Along the courtyard facade in the ground, lay lightning rods made of round steel ∅8mm and weld to the lightning screen and electrodes 50x50x5mm.. - Electrical installation works must be performed according to PUE RK 2015, SNiP RK 4.04-23-2004, SP RK 4.04-107-2013. -The calculation load at the input is accepted in accordance with RDS RK 4.04-11-2003 "Instructions for the calculation of city apartments and cottages." - Installation height: electrical sockets - 0.3 m, switches (on the door handle side) - 1.0 m, panel - 1.8 m (to the top of the panel).The heating cable deviflexTM/DTCE-30 is provided for heating the gutter funnels installed on the roof, the cable temperature is controlled by temperature controllers installed and powered in the elevators machine room from YATP-0.25.
