Early design is emphasis on the pursuit of low cost, to the recent consensus gradually formed, high efficiency and high reliability is the most important thing. For example, high lamp light pole electricity equipment capacity of 35. 4 kW, lighting electricity capacity of 66 kW, obligate lamp post advertising light boxes, public service ads
in the early design pay more attention to the pursuit of low cost. In the near future, a consensus has been gradually formed. High efficiency and high reliability is the most important. For example, high lamp and the pole has a capacity of 35 with electrical equipment. Reserve capacity is 66 kw 4 kw, lighting, lighting advertising light boxes, public service advertising light boxes, bus stations, traffic lights and other electrical load is 161. The power of the 6 kw, after calculation, the whole road calculation load is 263 kw. According to the design specification requirements and wu township new city longgang district road lighting engineering lighting special box type transformer layout, with three box-type substation for street lamp power supply. Transformer capacity is 125 kva. The box-type substation of power supply from the nearby road 10 kv line ( Or by the owner and the related management department to talk things over solve) 。 Box-type substation installation has a set of street lamp control terminal unit and intelligent power saving tank. Street lamp control with remote control, time control and manual control mode, for the street lamp management to choose from. Box-type substation should be set in the pavement outside the green belts, shall not take up the sidewalk. Street lamp power distribution using three phase four wire system. Each lamp is connected to a 220 v power supply, the loop voltage loss is about 5% ~ 7%. Measurement: box-type substation installation total electric energy metering device. In addition, in order to measure the different electricity prices of electricity load, advertising light boxes are set up electric meter separately. In every lamppost to set aside 400 watts of advertising light box load; Each shelter has a 5000 - watt standby power load; Every 1000 meters reserved public service advertisements on load 10 kw each intersection traffic lights reserved capacity of 3000 watts; And other spare circuit.
