Street lighting management



Challenges and drivers




Power management of public networks, which includes street lighting, is one of the important problems for human settlements. Public lighting accounts for up to 40% of total energy costs of human settlements.

The main task is to ensure the reliability of street lighting and due to this increase comfort and safety of residents. In addition, it allows to increase the attractiveness of local architectural sights in the night and to organize control of the lighting system for maximum power savings.

The solutions used in the system

For the management of street lighting, the following types of equipment:
Ambient light sensor and twilight switches
The relay and astronomical relay
Dimmers
Other devices
This equipment allows to minimize power consumption while maintaining maximum safety on the streets.

Remote control of lighting.

The remote switch is used when you want to have more than two points of light chain management. Remote switch the number of points of light control can be unrestricted, except when they are equipped with light indicators. Too many indicators illuminated may lead to the fact that the remote switch is automatically turned off. Manage remote switch mozhnotolko with launch buttons (push-button switches). Conventional switches can bring remote switch failed. The design of the remote switch, a rather complicated and in this article will not understand.

The remote switch is usually installed in the switchboard. At the exit of the protective device (in our case circuit breaker), phase are connected to input terminals of the remote switch and a start button. Relapsing wire lamp output pin connected via a remote switch. Zero are connected to the input coil remote switch. Wires reverse current pushbuttons connected via the exit coil remote switch. Supply chain management and have a common defense, but it can also be independent. This option is usually used when the control buttons are placed outside the house. To power the coil and ignition keys are used transformer, which reduces the voltage to the value necessary for the remote switch (usually it is equal to 12 V).

You can also use the remote and two-pole switches, which allow simultaneous unlock phase and zero wires. This option provides greater security, for example, in the management of outdoor lighting.
Some models of remote switches are designed for installation is not on the switchboard, and in other places, such as special mounting box to create a chain with a remote switch on the basis of a simple food chain.

There are also model launch buttons adaptirovannyhdlya hidden wiring. They are suitable for use in carrying out repairs in order to create a remote control of lighting devices in an existing chain. The small size makes it easy to launch buttons, put them in the normal mounting box for wiring devices, 60 mm in diameter
