Function Characteristics
- Flame retardant,non-pollution,it can be installed directly in the load center.
- Maintenance-free,easy tobe installed,low operating costs.
- The enclosure can be of Good moisture resistance,transformer can beput into operation withoutpre-drying under 100%humidity in the normal operation.
- Low loss,light weight and small volume,low noise,good dissipation of heat,it can be 150%rated load operation under forced air cooling conditions.
- Equipped with acomplete temperature protection control system to provide reliable protection for the safe operation of transformers.
- High reliability.The results of checking for the products that has been put into operation show that the reliability index has reached the international advanced level.
Structural Characteristics
Foil Coil:
Adopting the entire section ofcopper foil,together with the F-classturn insulation,low voltage winding is wound by the special
low-voltage foil winding machine.The foil coil resolves problems such as large short-circuit stress,ampereturn unbalance, poor heat dissipation,existing thewinding spiral angle and unsteady manualwelding quality due to low voltage and large
currentcoil.At the same time,the end of windingistreated with cast resin,solidification to make shape,moisture-proof and
anti-fouling,the lead for copper bar is welded by argon arc welding automatically.
Temperature Control Device:
the transformer adopts BWDK series ofsignal thermometer.The temperature components areembedded in the upper half of the low-voltage coil,can detectand display the temperature ofseparate phase coil automatically and continuously,also have the functions of over-temperature alarm and trip
Model and Meaning
Rated voltage and capacity:
The rated voltage of SCB18 dry-type transformer is usually 10KV/0.4KV, with a wide capacity range from 30KVA to 2500KVA, including various specifications such as 30KVA, 50KVA, 80KVA, 100KVA, 125KVA, 160KVA, 200KVA, 250KVA, etc. Connection group number: SCB18-160KVA dry-type transformer. The connection group number is Dyn11, Yyno
Temperature monitoring system:
Equipped with a comprehensive temperature monitoring and protection system, adopting an intelligent signal temperature control system, it can automatically monitor and display the working temperature of each three-phase winding on the same screen, automatically start and stop the fan, and have functions such as alarm and trip settings.
Energy efficiency and environmental impact:
SCB18 dry-type transformer meets the first level energy efficiency standard, with obvious advantages in no-load loss and load loss. Due to its oil-free design, it does not produce toxic gases and is environmentally friendly
