Rice. 2. Schematic diagram of lighting control circuits

Centralized shutdown of outdoor lighting is carried out by introducing into the control circuits an auxiliary contact of the relay of centralized shutdown RO on the centralized shutdown panel or an auxiliary contact of the double voltage reduction relay DSN installed in relay cabinets.

The place of installation of panels for centralized shutdown of outdoor lighting is determined by the project.

Objects are distributed into groups of emergency and working lighting for each controlled area for a specific design in accordance with the current instructions.

Rice. Fig. 4. Schematic diagram of lighting control circuits for up to seven objects when the control equipment of the nuclear facility or control room is located in the control room

Networks for remote control of outdoor lighting should be carried out with control cables laid in the ground or suspended on a cable along overhead line supports. Remote control networks are calculated from the condition that for reliable operation of magnetic starters, the voltage loss in the network should not exceed 15% at the time of switching on.

When used in circuits of magnetic starters with large starting currents, as well as at large distances between the outdoor lighting control point and power points, an intermediate relay is introduced into the remote control circuit. In this case, the cable section is selected according to the starting current of this relay. It is recommended to take complete control devices as outdoor lighting power cabinets: control boxes and control cabinets. Boxes and cabinets for supplying outdoor lighting are installed in the subscriber part of transformer substations.

The centralization of lighting control is often carried out according to cascade schemes, in which sections of the distribution lines of the outdoor lighting network are controlled by connecting the coil of the contactor of the second section to the line of the first, the coil of the contactor of the third section to the line of the second, etc. The number of sections should not exceed 10. This creates controlled direction of the cascade by means of successive inclusion of sections, in which the beginning of the first and end of the last sections of the cascade are brought to the control point and control of the state of the cascade.
