dry-type transformer epoxy resin casting three-phase transformer 200kva 630kva 800kva 1000

SCB11、SCB12、SCB13、SCB14、SCB18系列树脂绝缘干式电力变压器产品特点
After the shutdown, it can be operated without pre-drying. Under forced air cooling conditions, it can operate at 150% of the rated load with a temperature protection control system. According to the operation research of products that have been put into operation.
The structural characteristics of the SCB11, SCB12, SCB13, SCB14, and SCB18 series of resin insulated dry-type power transformers.
Box Coil: Low-voltage windings are made using continuous copper foil, together with F-grade turn insulation, wound on a dedicated low-voltage foil winding machine. The foil coil solves the problems of low voltage, poor heat dissipation, the existence of winding helical angle, and unstable manual welding quality. At the same time, the winding ends of our company are sealed with resin, solidified into shape, and are waterproof and dustproof. The copper busbars are automatically welded by hydrogen arc welding.
Temperature Control Device: The transformer uses the BWDK series signal thermometer, with the temperature measurement element buried in the upper half of the low-voltage coil. It can automatically detect and display the working temperature of each phase coil, and has over-temperature alarm and trip functions.
