product description:
ZGS series combined transformers, that is, American-type transformers, are series of products developed according to the needs of urban and rural power grid construction development and transformation. It is a transformer that combines transformer body, switchgear, fuse, tap changer, low-voltage power distribution device and other auxiliary equipment to meet various preparation requirements such as user energy metering, reactive power compensation, and low-voltage shunt. ZGS type combined transformer is used as an independent complete power distribution unit with rated capacity of 63~1600kVA in AC 50Hz, 6~10kV network. It can be used outdoors or indoors. It is widely used in industrial parks, urban residential quarters, commercial centers, high-rise buildings and temporary construction sites.
      Performance level of S9, S10 and S11 series oil-immersed transformers for 10kV combined transformers
      Note: a. According to user requirements, the high voltage tapping range of the transformer can be designed as ±2*2.5%;
Implementation standards:
Function and characteristics
â—Compact structure and small size, only about 1/3~1/5 of the same capacity domestic European-style box change, greatly reducing the floor space;
â— Fully sealed, fully insulated structure, no insulation distance, and reliable protection of personal safety;
â—High voltage is protected by combination of load switch fuses;
â—High-voltage wiring can be used for ring network, and can also be used for terminal, flexible power supply mode and high reliability;
â—Excellent transformer performance: low loss, low noise, low temperature rise; strong overload capability, short circuit resistance and strong impact resistance;
â— Meet various low-voltage feed-out requirements, which can be selected according to the plan or designed by yourself;
â—The cable head has 200A elbow cable connector and 600A T connector. The elbow cable connector is suitable for cable cross section of 35-185mm2. The T connector is suitable for cable cross section of 35-500mm2. The cable head material is divided into two. Copper core and aluminum core, both of which can be equipped with fully insulated zinc oxide arresters. The 200A elbow cable head can be loaded and unloaded, and it can also function as a disconnector.
Environmental conditions
    ◠The altitude does not exceed 100m;
    ◠Ambient temperature: -35 ° C ~ +40 ° C;
    ◠Relative humidity: the daily average is not more than 95%, and the monthly average is not more than 90%;
    ◠Installation location: no fire, explosion hazard, chemical corrosive gas and well ventilated place, the inclination angle is not more than 3 °.
Product Usage:
    Widely used in urban power grid reconstruction, residential areas and other public places and factories and mines, hotels, airports, railways, terminals, telling highways and other indoor and outdoor places.
Sub-box structure features:
    ◠Box change adopts the bin structure:
     The transformer body and the high-voltage components such as the high-voltage load switch, the plug-in fuse and the backup current-limiting fuse are respectively placed in the sealed oil tank, and the two boxes are horizontally arranged, completely separated by the partition plate , and the insulating wall-through sleeve is used for the partition plate . Wiring of transformers and load switches. It can be easily replaced without affecting the use of another box.
    ◠Two boxes of left and right layout advantages:
    1, two boxes do not affect each other:
     1 Preventing the upper tank from flowing into the bottom tank due to leakage of the partition, resulting in lack of oil in the upper tank (oil shortage or no oil causes the operating load switch to arc, posing a danger to the equipment and the human body);
     2 Another advantage is that the left and right layout is convenient for maintenance. When the transformer room and the load switch room are inspected, the two boxes do not affect each other, which is convenient and convenient. (If the upper and lower fuel tanks are all removed after the above-mentioned maintenance and repair of the transformer, the oil tank of the transformer can be opened, and the inspection is extremely inconvenient).
     2. The sub-tank structure solves the problem of contamination of the transformer oil by the fuse of the first-stage fuse of the load switch operation.
Technical Parameters:
      Load switch technical parameters:
      b. According to user requirements, the low voltage of the transformer can be designed to be 0.69kV.
      The load switch is oil-immersed, three-phase linkage switch, spring operating mechanism: it can be loaded with load opening operation, its separation speed is independent of the operation force, the form oil two station, four station T type, four station V type Available for selection.
