This intelligent integrated transformer substation is a nationalized type American box substation developed by our Company. As an
important power supply unit in the cable distribution network, it is an in tegrated prefabricated product of high voltage control,protection, power
transformation and power distribution. which is widely used in the urban and rural distribution network.The high voltage load switch and high voltage
fuse are put into the transfomer oil, so this product has two structure forms of one box and divided box with the transformer body. The oil box is of
full-sealed structure with oil temperature indicator, oil level gauge. pressure gauge, presure relief valve and oil drain valve to monitor the operation
condition of the transformer. This kind of products has three types of power supply modes ring network type, terminal type and power type. In order
to make the product meet the actual demands of the power grid in China better, our company promotes plug-pull dry type fuse and the fusing of the
fuse wire has no effect to the performance of transformer oil. According to the complicated degree of low voltage outgoing demands. this product has
three types of enclosure-standard type, reinforced type and integrated type, as a result, the clients and design agents have more choices.

Structural features
The frame structure of the box shell is made of channel steel and angle steel, which has high mechanical strength. The shell is made of aluminum alloy plate and other materials, with smooth and flat surface, beautiful products and good corrosion resistance. The base of the box body is 300- 600mm higher than the foundation.
All doors of the cabinet shell are opened outwards, with an opening angle greater than 90, and are equipped with a positioning device, a handle,a secret door and a secret lock which can prevent rain, blockage and rust. The boxes are all fully sealed anti-theft structures; In orderto ensure that the temperature of all electrical equipment does not exceed the maximum allowable temperature when running at the general ambient air temperature, the box does not have enough natural vents and thermal insulation measures. The box body of the pre-installed substation is provided with a special grounding conductor, which is provided with more than two fixed connection terminals connected with the grounding grid,
with obvious grounding marks. Grounding terminal is copper bolt with diameter not less than 12mm. The grounding conductor adopts copper tape, and its current density is not more than 200A/mmand its cross section is not less than 30mm2 so as to ensure that overheating does not occur andthe safety of surrounding objects is not affected when the maximum short-circuit current flows. The dynamic and thermal stable current borne by the special grounding conductor should be matched with the grounding mode of high voltage distribution equipment.
