ZGS系列预装式变电站

适用范围 Scope of application

　　ZGS系列预装式变电站适用于7.2KV和12KV环网供电，双电源供电或终端供电系统，作为高压配电计量，补偿控制和保护装置，高压侧还装有四工位负荷开关或二工位负荷开关，后备保护熔断器及插入式熔断器，低压侧按用户要求装配控制电器，配电电气，补偿装置及电能计量表等。

　　ZGS系列预装式变电站可用于室内，又用于室外，广泛运用于工业园区，商业中心，及高层建筑等各种场所。

　　ZGS series prefabricated substation is suitable for 7.2KV and 12KV ring network power supply, dual power supply or terminal power supply system. It is used as high voltage power distribution metering, compensation control and protection device. The high voltage side is also equipped with four station load switch or two station. Load switch, backup protection fuse and plug-in fuse, low-voltage side according to user requirements to install control appliances, distribution electrical, compensation devices and energy meters.

　　ZGS series prefabricated substations can be used indoors and outdoors, and are widely used in industrial parks commercial centers, and high-rise buildings

结构特点 Structural features

　　该系列产品箱体结构分为前、后两部分。前面为高低压操作间隔。高压间隔内包括高压端子、负荷开关、无载调压分接开关、插入式熔断器，压力释放阀、油温计、放油阀。低压间隔内包括低压端子，后部为注油箱体及散热片，变压器绕组和铁芯，高压负荷开关及保护用熔断器都在储油箱中。

　　The box structure of the series is divided into front and back parts. The front is the high and low voltage operation interval. The high-voltage interval includes a high-voltage terminal, a loadswitch, a no-load tap-changer, a plug-in fuse, a pressure relief valve, an oil temperature gauge,and a drain valve. The low voltage interval includes a low voltage terminal, the rear part is a fuelt ank body and a heat sink, the transformer winding and the iron core, the high voltage load switch and the protection fuse are all in the oil storage tank.
