JB/T10088-2004 "6-500kV power transformer sound level"
The characteristics of product structure
The high voltage coil: a multi section cylinder type structure, 630kVA and above a cooling air duct, which belongs to non filler glass fiber reinforced casting system.
The low voltage coil: 315kVA and above the coil structure foil, resin end seal, the surface is covered by high temperature curing epoxy resin.
The core: the "step-by-step" laminated way laminations, pull type structure.
The clamp: shaped by stamping steel bending, compared with general clamps, structure increases tensile side, the ventilation slot, so that the iron core and clamp the compact, no deformation, good ventilation performance of the transformer, has obtained the national patent.
The shell is made of corrosion-resistant: aluminum, aluminum and aluminum alloy corrosion wear flowers grid plate material assembly, with ventilation and good protective properties.
The cooling system: fan with low noise, large air quantity, low loss of flow type fan.
The temperature display device: temperature display device has a display cycle hot spot temperature three-phase coil, display the highest temperature phase, automatic control of the air cooling system of start and stop, over temperature alarm, computer networking, remote display and fault memory functions.
Product selection guidance
The large-scale thermal power plants, large hydroelectric power plant, nuclear power plant and other important facilities in oil free distribution device is preferred to select the type of transformer.
The fire safety requirements higher places such as: high-rise building, port, wharf, airport, theaters and other densely populated buildings preferentially select the type of transformer.
The compact site case preferentially select the type of transformer.
The oil immersed transformer emergency oil pollution on the environment to solve the priority selection of the transformer.
Outdoor box to the important building fireproof distance is not the preferred variable in this type of transformer.
⑥ and residential conjoined distribution station preferentially select the type of transformer.
The variation of environmental temperature is larger, or relatively low environmental temperature area, transformer with filler cast crack easily, give priority to choose the type of transformer
