Why high-speed broad daylight also open the lamp? Not afraid of wasting electricity? - China lighting network

When travel, believes that many people's first choice is high iron! Both comfortable temperature of air conditioning and seat is equipped with electric outlets, high-speed rail with the advantages of safety, convenient, fast and comfortable quickly come to the fore. Do you know? Speed of 350 km of high-speed power consumption per hour 9600 degrees, the speed of 250 km of high-speed power consumption per hour 4800 degrees, a trip to the speed of 250 km of high-speed train from nanjing to suzhou to nearly 5000 degrees of electricity! You know, 5000 KWH equivalent to 280000 phones full of electricity consumed electricity! Enjoying high iron bring comfortable experience at the same time, we have found a phenomenon, whether it is day or night, high-speed rail the light is always on the car, car is always a bright lights, too. When someone has a question, in broad daylight why turn on the light, do not waste of electricity? Why did the lamp has been lit inside? Say car first, train on the road through the terrain is different, sometimes it is plain, is sometimes basin, even the hills, mountains, the light will be changed by outdoor environment, in the shadow of the mountain slope is relatively dark outdoor light, in the direct sunlight the light is more dazzling. Car Bai Tianliang lamp is for everyone to adapt to changes in train in strong light, convenient to everyone in the long journey back to play, enjoy the food and sweet? Select reason for high-speed rail travel a little bit more! 'Renaissance' also has a variety of lighting control mode, the car lights will automatically adjust according to the outdoor situation, at the same time at the top of the corridor lights, brightness, light changes in temperature, are free to adjust, isn't it be great! Why car lights have been lit? Low lighting effect train road may after the tunnel, and in extreme weather, such as rain, fog, snow, etc under the condition of low visibility, driving lights and car lights is a function, light the way forward. Low warning to remind the railway signal into the auditory and visual, sound is a kind of acoustic signal, remind the station staff, train station or the outbound. Light horns not yet, still have to turn on the light. We all know that light travels faster than sound, we will see first before horns lights, lights and horns of double insurance, remind staff and platform waiting you, pay attention to keep a safe distance. So, Gao Tieyong electricity come from? Since the high speed rail on the lamp is so important, if the power went out again? Gao Tieyong electricity is where? Due to high iron itself without energy, therefore can only be provided by the electric traction power supply system, and the powerful power supply system mainly includes the substation and catenary. Is there any difference between high-speed electricity utilization and family? Unlike households, high-speed rail in the process of travel, not always connected to a power grid, often through a period of about 100 meters without power range, power train, with inertia slip this period of interval. 220 v as the daily electricity class, we must be familiar. And although the high-speed electricity for single phase voltage, but the voltage grade is as high as 25 ( 27. 5) Kv. High-speed power really safe? Maintenance staff will be in the absence of HSR on catenary outage maintenance operations in the morning, and arrange personnel during the day along the railway inspection tour nest, presence of floater near, remove trees that may cut line at the same time, avoid short-circuit trip influence the safe operation of the high-speed catenary device. Besides high iron, mu trains per vehicle built-in battery, for pantograph run when the train started, also can be used as a security and high-speed rail of a power failure the emergency supply of auxiliary electrical system. So the high-speed rail in the general case is not power, you can rest assured ~ YanZhiXiang
