PRODUCT FEATURES
The epoxy resin cast 200kva Dry Transformer produced by Shanghai Industrial Transformer Co., Ltd. is developed and designed in cooperation with Shenyang Transformer Research Institute by introducing advanced foreign technology. The product reliability index has reached the international advanced level.
SGOB 200kva Dry Transformer is safe, flame-retardant and fire-proof, pollution-free, and can be directly installed in the load center. It is maintenance-free, easy to install, has low comprehensive operating cost, low loss, good moisture-proof performance, can operate normally at 100% humidity, and can be put into operation without pre-drying after shutdown. It has low partial discharge, low noise, strong heat dissipation function, and can operate at 150% rated load under forced air cooling conditions.
SGOB 200kva Dry Transformer are now widely used in high-rise buildings, commercial centers, airports, stations, docks, subways, factories, underground distribution stations, offshore oil drilling platforms, power plants and other places with harsh environments and use conditions.
Main materials and features
The coil uses F-class insulated copper wire as conductor and glass fiber and epoxy resin composite material as insulation. Its expansion coefficient is close to that of copper conductor and has good impact resistance, temperature change resistance and crack resistance. All components of glass fiber and epoxy resin are self-extinguishing and will not continue to burn. At the same time, the high-voltage coil is cast with epoxy resin under 1mbar vacuum state, and there are no bubbles inside the coil, ensuring that the partial discharge of the coil is small. At the same time, the loss of the transformer is effectively reduced.
The iron core of the transformer is made of 30EH120 series of high-permeability cold-rolled silicon steel sheets with orderly grain orientation imported from Nippon Steel, Japan, with 45° full-bevel joints and four-level step-by-step stacking. The surface of the iron core is sealed with insulating resin paint to prevent moisture and rust, and the two clamps and fasteners have anti-corrosion protective layers. The entire iron core adopts a non-stacked iron yoke and steel pull plate structure, which effectively reduces no-load loss, no-load current and iron core noise.
For low voltage and high current coils, the short circuit stress is large when short circuit occurs, and the number of low voltage turns is small. The larger the low voltage current is, the more prominent the problem of unstable ampere-turns will be when the wire winding type is used. The heat dissipation problem also needs to be considered. At this time, the use of foil winding for low voltage can better solve the above problems. First of all, foil products do not have axial turns and axial winding spiral angles. The ampere-turns of high and low voltage windings are balanced, and the axial stress of the transformer is small when short circuit occurs. Secondly, due to its thin insulation, multi-layer air ducts can be set at will in the process, and the heat dissipation problem is also better solved. The internal welding of the coil adopts xenon protection welding on the fully automatic foil winding machine, which has high precision, low welding resistance, and no external welding process. DMD insulation is used between the winding layers, and the ends are sealed and cured with resin after winding.
The cross-flow top-blowing cooling fan is adopted, which has the characteristics of low noise, high wind pressure, beautiful appearance, etc., and enhances the overload capacity of the transformer. The temperature control adopts an intelligent temperature controller to improve the safety and reliability of the transformer operation.
