产品简介
Brief introduction to the products

ZGS□-12预装式变电站(亦称美变)是本公司参照美国箱式变压器研制出的新型成套配电设备,是将油浸密封式电力变压器与高、低压电器元件进行优化组合,通过结构的优化,开关设备尽量小型化,大大缩小了组合变压器的占地面积,其体积只相当于同等容量欧式箱变的1/3~1/5,具有体积小、噪音低、供电可靠、结构合理、安装灵活、操作方便,可最大限度的深入负荷?#34892;?#31561;优点。广泛适用于住宅小区、商业?#34892;摹?#36710;站、工矿企业、机场、铁路、学校、医院、高层建筑等场所。

The ZGS □-12 prefabricated substation (also known as the American substation) is a complete set of novel power distribution equipment developed on the basis of the American box-type transformers, which optimizes the combination of oil-immersed power transformers with high and low voltage electrical components.Through structure optimization and miniaturization of the switching equipment, it has greatly narrowed the area of transformer combination. Its volume is only equivalent to 1/3 ~ 1/5 of the European box-type transformers with the same capacity. It is small in size, low in noise, rational in structure, flexible in installation, easy in operation and has maximum depth in the load center. It is widely used in residential quarters, commercial centers, railroad stations, industrial and mining enterprises, airports, railroads, schools, hospitals and places of high-rise buildings.

 The conventional American box-type transformer is of a QQ截图20161110095517.pngstructure divided into two parts. The front part is high and low voltage cabin, including 10kV high voltage load switch, no-load tapping operating handle, plug-in fuses, pressure release valve, oil thermometer, oil level gauge, oil injection hole and oil discharge valve. The rear part is oil tank and heat sink, transformer windings and core, high voltage load switch, no-load tapping switch and fuses for protection. The oil tank is of a sealing structure or of a QQ截图20161110095539.png structure, including high voltage cabin, transformer and low voltage cabin.


High Voltage of American Box-Type Transformer

The high-voltage terminals (single pass or double pass) of the ZGS Series American Box-Type Transformer fitted with high voltage bushing are used to connect elbow-type cable plug or elbow-type full insulated arresters and enclose the live parts in an insulation to form an insulation structure. The terminal surface is not charged to ensure personal safety. In case of emergency, the cable plug can be charged and also play the role of the load switch. According to the requirements, the live display or the fault indicator can be mounted on the cable plug. A wall hanging is welded on the wall of the front cabin near the high-voltage bushing for fixing the support type insulation bushing joint. When unplug the live cable plug, it could be pluged immediately on the support type bushing joint.


Fuse of American Box-Type Transformer

The ZGS Series American Box-Type Transformer adopts two sub-series protection with the plug-in fuse and back-up current-limiting fuse. The protection is advanced, economic, reliable and easy to operate. Plug-in fuse is used for over-current small-scale breaking (including the short-circuit fault at the low-voltage side). In case of the transformer overload and high temperature, the fuse is mainly used to protect the combined transformer. The backup current-limiting fuse is used for the wide range fault current breaking, mainly the short-circuit fault at the high-voltage side of the transformer, for cutting off the transformer and protecting the high voltage transmission line.


10kV Load Switch

The 10kV oil-immersed load switch is a three-phase linked switch with springs used for breaking and closing operation of the load. The load switch is of two position or four position structure. The two position switch is used for the terminal type power supply while the four-position switch is used for the ring or double power supply.


Low Voltage Cabin

In the low-voltage cabin, there are outgoing terminals. According to the requirements, fixed in the cabin there are low- voltage main and branch circuit breakers, low-voltage current and voltage measuring meters and automatic reactive power compensation devices. In accordance with the user's requirements, the axial flow fan could be installed at the top of the low-voltage cabin.  the cooling of the fan could be automatically controled by the special temperature controled equipment according to the temperature in the cabin. The integrated distribution tester with the function of telemetry and remote information and supplemented with low-voltage and under-voltage control device could be fixed according to the requirements. The protection of voltage loss and single-phase under- voltage could be realized to avoid damage to transformers and electrical loads.

Small Investment for Users, Small Building Area, Convenient Installation, Speedy Power Supply

Less investment: investment less than the European-style box-type transformer or substation construction. 

Simple and convenient installation: only tighten the four mounting bolts, connect cables and the ground of the elbow-type arresters.

Speed Power Supply: Determine only the capacity of the transformers when they are installed. The calculation of the electric parameters such as breaking current, dynamic stability and relay protection are not necessary to be provided for ordering.


Safe and Reliable Power Supply

The ZGS Series American Box-type Transformer adopts fully closed design with three-point grounding. There are no conductive components on the surface of the shell. There is no insulation distance. The personal safety could be ensured. The high voltage line has fully insulated elbow-type cable head easy to plug. The insulated joystick operation can ensure personal safety.


Simple and Convenient Maintenance


The plug fuses, cable plugs and the elbow-type lightning arrester structure make the replacement very convenient. The fully closed transformer avoids the insulating oil from contact with the air. So that the transformer is maintenance free.
