    如何解决集装箱的供电问题?

    来源:http://lasimao.com/ 日期:2019-12-20 发布人:admin
      如何解决集装箱移动房屋的现场供电问题?一般有三种方式:
      How to solve the problem of on-site power supply for container mobile houses? There are generally three ways:
      答:柴油发电。如低速发电机,高速发电机
      A: diesel power generation. Such as low-speed generator, high-speed generator
      优点和缺点。低速柴油发电机的使用寿命、磨损、防护性能均优于高速柴油发电机。高速的优点是体积小,比较适合装料等地方有体积限制,缺点是保护麻烦,寿命不如低速。
      merits and demerits. The service life, wear and protection performance of low-speed diesel generator are better than that of high-speed diesel generator. The advantage of high speed is small volume, which is more suitable for loading and other places with volume limitation. The disadvantage is the trouble of protection, and the service life is not as long as low speed.
      二:风力发电
      2: Wind power
      优点和缺点:使用可再生能源,减少碳排放。进步是一种可再生能源的利用。中国国家气象局的数据显示,中国目前在三峡有四座风力发电站。风能的进步,可以改变我们依赖火电的能源问题,减少火电,京都议定书。电源要求逆变器的频率,一般整流型逆变器先转换成50hz。选择失速式风机时,对电网的影响太大。现在选择可变螺旋桨风机,以减少对电网的影响,但仍有一定的影响。该波形不是测量风电正弦波形的方法,电网的容量是toms的一个接口。风力发电设备太阳能发电的利与弊:环保、安全、易保护,可以说是取之不尽,取之不竭,效率不高15%,不稳定,地域性强,受天气影响。
      Advantages and disadvantages: use renewable energy to reduce carbon emissions. Progress is the use of renewable energy. China now has four wind power stations in the Three Gorges, according to the National Meteorological Administration. The progress of wind energy can change the energy problem that we rely on thermal power, reduce thermal power, Kyoto protocol. The power supply requires the frequency of the inverter. Generally, the rectifier inverter is converted to 50 Hz first. When the stall fan is selected, it has a great influence on the power grid. Variable propeller fans are now selected to reduce the impact on the power grid, but there is still a certain impact. This waveform is not a method to measure the sinusoidal waveform of wind power. The capacity of power grid is an interface of Toms. Advantages and disadvantages of wind power generation equipment solar power generation: environmental protection, safety, easy protection, can be said to be inexhaustible, inexhaustible, efficiency is not high 15%, unstable, strong regional, affected by the weather.
      活动室临时供电组织通常包括:用电量计算;选择电源;判断变压器;安排配电线路,确定导线截面。
      The organization of temporary power supply in the activity room usually includes: Calculation of electricity consumption; selection of power supply; judgment of transformer; arrangement of distribution lines and determination of conductor section.
      1. 现场用电量判断
      1. On site power consumption judgment
      (一)全厂使用的机器用电设备、其他用电工具和照明用电的数量;
      (1) The quantity of electrical equipment, other electrical tools and lighting used by the whole plant;
      (二)建设高峰期同时用电的机器设备在总建设计划中的最高数量;
      (2) The highest number of machines and equipment using electricity at the same time during the construction peak in the total construction plan;
      (3)工作所需的各种机器设备。
      (3) All kinds of machines and equipment required for work.
      单班活动室建设,用电计算不能考虑照明用电。
      For the construction of single shift activity room, the power consumption calculation cannot consider the lighting power consumption.
      2、选择现场电源
      2. Select field power
      (1)在选择移动房屋场地临时电源时,应考虑其原因
      (1) When choosing the temporary power supply for the mobile house site, the reasons should be considered
      活动室工程及设备装配工程数量及施工进度;
      Quantity and construction schedule of activity room works and equipment assembly works;
      各施工阶段的用电需求;
      Power demand of each construction stage;
      建设场地的规模;
      Scale of construction site;
      (4)施工现场电气设备的分布及间距电源的距离;
      (4) The distribution of electrical equipment on the construction site and the distance between them and power supply;
      (5)现有电气设备的容量。
      (5) Capacity of existing electrical equipment.
      (2)临时供电的几种方案
      (2) Several schemes of temporary power supply
      (1)完成由移动房屋工地邻近的电力系统供电,包括全面启动前的永久性供电以外的工程要做得更好,设置变电站。
      (1) To complete the power supply from the power system adjacent to the mobile housing site, including the permanent power supply before full start-up, the project should be better done, and the substation should be set up.
      (2)移动宅基地邻近的电力系统只能供应一部分,仍需扩大原有的供电或增加供电系统来弥补其不足。
      (2) The power system adjacent to the mobile homestead can only supply a part of it, but it still needs to expand the original power supply or increase the power supply system to make up for its shortage.
      适用于就近使用高压电网的临时配电变压器。
      It is applicable to the temporary distribution transformer of nearby high-voltage power grid.
      (4)移动房屋选址在偏远地区,当没有电力系统时,由临时电站完成供电。
      (4) Mobile houses are located in remote areas. When there is no power system, the temporary power station will supply power.
      (3)临时电站一般包括内燃发电机、火电站、火车电站、水力发电站。
      (3) The temporary power station generally includes internal combustion generator, thermal power station, train power station and hydropower station.
      3.判断变压器输出功率
      3. Judge the output power of transformer
      采用的导线截面应同时满足上述要求,即以截面积最大的导线截面为准。从线材产品目录中选取的线材芯截面也可以根据具体情况来把握矛盾的症结所在。通常在移动建筑工地和给排水工地作业线路比较长,线段由压降选择;移动工地配电线路较短,可根据允许电压选择导线截面。对于小负荷架空线路,通常选择机械强度。
      The cross section of the conductor used shall meet the above requirements at the same time, that is, the cross section of the conductor with the largest cross section shall prevail. The core section selected from the wire product catalog can also grasp the crux of the contradiction according to the specific situation. Generally, the operation line in the mobile construction site and water supply and drainage site is relatively long, and the line section is selected by the voltage drop; the distribution line in the mobile construction site is relatively short, and the wire section can be selected according to the allowable voltage. For small load overhead lines, mechanical strength is usually selected.
