Our company all box-type transformer and switching substations of production components and computer protection, a more professional and more reliable and more cost-effective!
预装箱式变电站是将配电网末端变电站预先在工厂内制造装配，包括高压间隔、控制设备、低压间隔、控制设备、内部接线、计量、补偿、避雷器等等辅助设备配置在一个公用外壳内，并通过型式试验的一种成套变电站，是城乡变电站改造的新装备，普遍适用于电网系统内终端配电、矿山、工厂和铁路、高层建筑、商业中心、居民小区、城市路灯照明等。由于我国西北地区气候条件恶劣，施工周期短的特点，预装箱式变电站特别适合此类地区。广泛应用于城网建设，是取代建筑配电房的新型配电装置。
Prefabricated substation is a substation distribution network terminal in advance manufacturing and assembly in the factory, including high pressure interval, control equipment, low voltage interval, control equipment, internal wiring, metering, compensation, lightning arrester, etc. auxiliary equipment disposed within a common housing, and through a complete set of substation type test, transformation of urban and rural substation of new equipment, universally applicable within the grid distribution system terminals, mines, factories and railways, high-rise buildings, commercial centers, residential areas, urban street lighting. Due to adverse weather conditions in Northwest China, the construction period is short features, Prefabricated substation is particularly suitable for such areas. Widely used in urban network construction, to replac the power distribution room building new power distribution equipment.
相对于传统意义上的变电站，具有以下优势：
With respect to the substation in the traditional sense, it has the following advantages:
1.投资较少，占地面积小，相对于传统意义上的普通变电站，预装式变电站不需建设控制室和高压室，占地面积小，现场只需按箱变基础的尺寸，制作一个钢筋混凝土基础即可。
1. Less investment, small footprint, compared to ordinary substation in the traditional sense, prefabricated substation without construction control room and high-pressure chamber, small footprint, live simply press box transformer based on size, making a reinforced concrete foundation.
2.设计、施工周期短。设计时，设计人员根据变电所的实际要求，只需作出一次主接线图和箱外设备的设计，然后选择由厂家提供的箱变规格和设备型号参数，做出箱变内部设备平面图。真正做到变电所建设的工厂化，以缩短设计制造周期。施工时只要将出厂时设备已安装好的箱变固定安装在钢筋混凝土基础上，进行箱外主变、外部电缆进线等必要的一、二次连接，即完成了安装，施工期可缩短一半以上。
2. Design, short construction period. When the design, designers according to substation actual requirements, just make one main wiring diagrams and equipment design outside the box, then selec the box change specifications provided by the manufacturer and device model parameters, make substation changes the internal equipment plan. Truly make substation construction factory, to shorten the design and manufacturing cycle. As long as the construction of the factory-installed equipment has been installed in the tank becomes fixed on a reinforced concrete foundation, carried the box outside the main transformer, the external cable entry and other necessary one or two connections, the installation is complete, the construction period can be shortened by more than half.
3.提高变电所运行的可靠性。由于箱式变电所采用控温，防尘、防潮、仿腐等一系列措施，使安装在箱体内的二次保护，运动装置及开关设备等处于良好的工作环境中，再加上设备布置紧凑，一、二次设备的集成化程度高，减少了不必要的连线和节点，降低了电气回路中的故障率，从而使变电站所运行的可靠性大大提高。
3. Improve the reliability of operation of the substation. since the box-type substation by temperature, dust, moisture, corrosion and a series of measures, the secondary protection, sports equipment and switching equipment installed in the cabinets and the like in a good working environment, plus the compact equipment layout, a high degree of integration of first and secondary equipment, reduce unnecessary links and nodes, reducing the electrical circuit failure rate, so that the reliability of the substation operation greatly increased.
4.采用先进技术，综合自动化程度高，配置灵活，实现了无人值守。高集成化。且维护保养极其简单。在调度中心或集控站就可以简单方便的监控或遥控，实现了无人值守。
4. Using advanced technology, comprehensive high degree of automation, flexible configuration, to achieve unattended. High integration. And maintenance extremely simple. Dispatch center or centralized control station can be simple and convenient monitoring or remote control, to achieve unattended.
