       概述
       美国GE企业及Cooper企业生产的小型箱式变电站是云顶集团4118com-云顶集团4118com的代表。
       云顶集团4118com-云顶集团4118com是将云顶集团4118com-云顶集团4118com身、开关设备、云顶集团4118com-云顶集团4118com、分接开关及相应辅助设备进行组合的云顶集团4118com-云顶集团4118com.其形状一般为“品”宇型。前部为接线柜.面板上布置着端子、云顶集团4118com-云顶集团4118com、插入式云顶集团4118com-云顶集团4118com、分接开关等件;面板上布置着端子、油位计、油温计、压力表、泄压阀等。后部为油箱及散热郁分,云顶集团4118com-云顶集团4118com器身及高、部件等均放置在油箱内,由于高、元件等采用油绝缘,缩小了绝缘距离,使整体体积明显缩小,约为箱式变电站的l/3~1/5。
       云顶集团4118com-云顶集团4118com(美式箱变)的云顶集团4118com-云顶集团4118com高套管出在侧面,由一个固定在云顶集团4118com-云顶集团4118com侧面的金属箱子封住(有门),将云顶集团4118com-云顶集团4118com、云顶集团4118com-云顶集团4118com放在云顶集团4118com-云顶集团4118com油箱内,电缆用橡胶电缆头插入出线端子上.给电缆头上另装避雷器。侧只出4个端子,要用电缆引至另外一处室,在该室设开关保护。由于供电简化,无电压、电流互感器,屏另外设置,这样体积非常小。以GE500kVA 10/0. 4kV云顶集团4118com-云顶集团4118com为例,尺寸为1. 7m×6m×1. 4m。
       由于无屏,云顶集团4118com-云顶集团4118com在国内采用受限,只能用于户外场地小,而又另有室的场所。云顶集团4118com-云顶集团4118com均不设计量柜,计量设在用户处。
       沈阳云顶集团4118com-云顶集团4118com研究所已于1999年提出了云顶集团4118com-云顶集团4118com标准并供应图样,已有多家厂通过鉴定。还有数家云顶集团4118com-云顶集团4118com厂自行设计生产。
       箱式变电站有变电站的功能,有高、开关,保护齐全,并带有计量装置,可以起到一个变电站的作用。而云顶集团4118com-云顶集团4118com目前只有简单的侧操作保护功能,而侧如要有功能,需另设置柜或利用其他土建房间设柜,才能完善其功能。
 
Combined Transformer
 
    Outline
    United States, GE and Cooper produced a small box-type transformer substation is modular representatives.
    Combined transformer is the transformer body, switchgear, fuses, tap the corresponding auxiliary equipment and transformer combination of its shape is generally "product" Yu type. The front of the wiring cabinet. On the front panel layout with high-pressure high-voltage terminals, high voltage load switch, plug-in fuse, high voltage tap and other pieces; low-voltage terminals on the front panel layout of the oil level gauge, oil temperature meter, pressure gauge, pressure relief valve. Rear of the tank and heat Yu points, the body of the transformer and high voltage components etc placed in the tank, due to the high and low voltage components, such as the use of oil insulation, reducing the insulation distance, so that the overall volume was significantly reduced, about box-type substation of l / 3 ~ 1 / 5.
    Combined transformer (American box changed) high and low voltage transformer bushing out of the side, the side of the transformer by a fixed metal box sealed (with doors), the high voltage load switch, fuse on the transformer tank, the cable Rubber cable head into the high pressure outlet terminal. arrester fitted to the cable head another. Only the four low-pressure side of the terminal, use the cables to another cited a low voltage power distribution room, the room is located in the low pressure switch protection. As the high voltage power supply to simplify, no voltage, current transformers, low voltage screen another set, so the volume is very small. To GE500kVA 10 / 0. 4kV combined transformer, for example, size is 1. 7m × 6m × 1. 4m.
    As the low-voltage distribution panel, modular transformer in the domestic use is limited, only for a small outdoor space, but otherwise low-voltage power distribution room places. Modular design of the transformer are not the amount of cabinets, located in the user at the metering.
    Shenyang Transformer Research Institute in 1999 proposed a combined transformer standards and supply patterns, there are many plants through identification. There are several transformer factory to design production.
Box-type substation substations function, high and low voltage switchgear, protection and complete, and with a measuring device that can play the role of a substation. The modular high-voltage transformers are only simple operations side protection, but must be functional, such as low-pressure side, an additional set low cabinet or room counters using other construction in order to improve its function.
