Street lighting boxes are used to distribute energy and protect elements from short circuits and overloads..
What is street lighting
street lighting (UO) It provides better visibility in the dark, especially necessary in areas densely populated by people. MA significantly It reduces the number of accidents of traffic accidents (According to various sources – on 30-45%), as well as reducing the threat of crime.
but, for, to street lighting to fulfill its task, It requires not only the street lights, but such an important element, like boxes of street lighting (briefly YAUO box). They are allow control the time of switching on and off lighting streets, parks or squares.
The most common group of NUO are controlled switchgears digital sensor, in which the hours of switching on and off the lighting are entered based on data from the sunrise and sunset tables. This solution minimizes the maintenance of YAUO, replacing Twilight switches, used so far.
Also today, manufacturers of lighting controllers are actively introducing street lighting control systems using remote monitoring and control.. These systems allow you to intelligently select the On and Off, continuously adjust the light intensity or decrease power.
The main advantages of such solutions are:
- full control and management of the system through the website or mobile app;
- GPS-time synchronization – GPS-time and geographic location, taken from GPS, can accurately calculate the sunrises and sunsets on a given day and location;
- link: GPRS, SMS;
- the possibility of emergency operation / turn off the lights (from a mobile phone or from the website);
- monitoring and analysis of network parameters in real-time: current, voltage, power usage, active power, reactive power;
- remote sharing software and GPRS settings after;
- immediate information about the emergency situation, t. it is. the loss of the supply voltage, the loss of the individual phases, excess / power reduction, the opening of the box;
- the possibility of adapting road lighting to the current movement (on the basis of data of external traffic management system).
What are YAUO?
Boxes made of street lighting on the basis of the metal casing and casing of glass fiber reinforced thermoset plastic (SMC composite). Most often produce switchgears in thermosetting housings of class II insulation with varying degrees of tightness and in metal shells:
- body type OSZ and KSZ – IP44, I 10,
- sealed housing HYDRA – IP 65-66, I 10,
- in metal enclosures from a wide range of materials:
- carbon steel;
- steel coated with zinc or aluzinc;
- aluminum;
- stainless steel.
Council! If you decide to buy YAUO, we recommend you to pay attention to products made of aluminum sheet covered with powder paint in any color or plastic (thermosetting polyester, fiberglass-reinforced). Aluminum sheet box has a double roof to prevent condensation. The structure is mounted on a concrete base, a lightweight aluminum sheet construction facilitates transportation and setting.
Depending on the assembly seats should be allocated as follows YAUO:
- freestanding cabinets with an additional foundation,
- cabinets are adapted for installation on a building facade or a column.
Depending on the needs of street lighting is equipped with a box:
- tires PEN;
- fuses;
- kontaktorami;
- switches;
- signal lamps;
- control relay and other devices.
Fuse bases can be terminated with V type clamps or screw terminals. Connections are made using PEN or PE bus + N.
