Remote control is carried out by PM magnetic starters installed on the supply lines of outdoor lighting objects. Magnetic starters are controlled from control cabinets automatically using a photo relay of the external lighting control device AO. It is possible to control manually remotely using switches B in the control circuit by selecting the mode using the PU control mode switch.

Rice. 2. Schematic diagram of lighting control circuits

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

The installation location for centralized switch-off of external 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 current instructions.

Rice. 4. Schematic diagram of lighting control circuits for up to seven objects when placing control equipment for a nuclear power plant or control room at a control point

Networks for remote control of external lighting should be carried out using 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 moment of switching on.

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

Centralization of lighting control is often carried out using cascade schemes, in which sections of the distribution lines of the outdoor lighting network are controlled by connecting the contactor coil of the second section to the line of the first, the contactor coil of the third section to the line of the second, etc. The number of sections should not exceed 10. In this case, a controlled direction of the cascade through sequential inclusion of sections, in which the beginning of the first and the end of the last section of the cascade are brought into the control point and monitoring the state of the cascade.

Remote control of outdoor lighting should be carried out according to the light calendar and the schedule for turning on and off installations for a populated area, according to the operating hours of lighting installations per month for settlements located at different latitudes, which can be used to plan electricity consumption.

Deviations from the schedule for turning on and off installations drawn up for clear weather due to unfavorable weather conditions are allowed for no more than 15 minutes, i.e., a total daily increase in the operating time of installations is 30 minutes (15 minutes in the evening and 15 minutes in the morning).

It is recommended to check the time of switching on or off the installations using photoelectric automatic devices of types, etc., configured for the specified range of illumination, in control rooms.

Photosensors must be installed in accordance with their operating instructions. General requirement is to orient the photo sensor to the north so that direct sunlight does not fall on it during the day. Illumination of the photosensor by extraneous light sources - lamps, spotlights, etc. should also be excluded.
