The description of SCB 10 epoxy resin cast dry type power transformer
SCB 10 epoxy resin cast dry-type power transformer is a low-noise and low-loss dry-type transformer with good performance indicators at present. It can be used as a replacement product of various distribution transformers. SCB 10 epoxy resin cast dry-type power transformer is especially suitable for the promotion and use of important places such as urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, subways, underground power stations, test rooms, stations, terminals, airports, and combined substations.
The features of SCB 10 epoxy resin cast dry type power transformer
Low loss: The no-load loss of the SCB 10 epoxy resin cast dry type power transformer is reduced by more than 35%. The energy saving effect is excellent, the operation is economical and the maintenance is free.
Low noise: The noise level of the SCB 10 epoxy resin cast dry type power transformer is lower than the current professional standard JB / T10088-1999 “6-220KV transformer sound level” by more than 10-15 decibels.
Low partial discharge: The resin mixture adopts two foreign stirring methods and vacuum film degassing technology to make the mixture stir evenly and eliminate air bubbles in the mixture. The SCB10 epoxy resin cast dry type power transformer has very low partial discharge and can be controlled below 5PC.
The high and low voltage coils are cast under vacuum and pressure, so that the resin insulation has both full encapsulation and inter-turn leaching. The casting body of SCB 10 epoxy resin cast dry type power transformer has a dense solidified structure which is flame-retardant, explosion-proof, and does not pollute the environment. Insulation materials such as glass fiber wound coils have self-extinguishing characteristics and no arc will be generated due to short circuit. The resin will not generate toxic and harmful gases under high heat.
High mechanical strength: The resin with filler makes the expansion coefficient difference in the casting body small, the curing shrinkage rate is small, the internal stress is small, and the hardness of the cured SCB 10 epoxy resin cast dry type power transformer is high. The prefabricated reinforced material has a dense structure like reinforced concrete, so its mechanical strength is greater than that of pure epoxy resin, and it can withstand sudden short-circuit electric force without damage.
High electrical strength: Both high and low voltage coils are cast into a fully sealed structure in a vacuum with good insulation and arc resistance and moisture resistance that can withstand electrical overvoltages, operating overvoltages, transient overvoltages, and long-term operating voltages.
High heat resistance: The high and low voltage coils are thin-layer epoxy-encapsulated insulation and have a large thermal conductivity and good heat dissipation performance. The cooling method is generally natural air cooling with a forced air cooling system can also be configured. The insulation heat resistance grade can reach H grade, the average temperature rise is allowed to rise 12.5K, the limit temperature can reach 180 ° C, it has high heat resistance strength, and the service life of SCB 10 epoxy resin cast dry type power transformer is more than 30 years.
