SC(B)10 20kV class, 35kV class dry type transformer

SUMMARY

This series of products is used to directly reduce the power supply of 20kV and 35kV power grids to 400V power distribution power supply or 10kV power transmission power supply. Because of its significant advantages, it is used in more and more projects. Its main advantages are:

Reducing the construction of land occupation and multi-level substation projects has significant social benefits. Save engineering investment and improve economic efficiency. Reduce the 10kV power transmission and transformation link, so that the operation and maintenance costs are significantly reduced. The use of high voltage and small current instead of low voltage and large current transmission reduces line losses and reduces line operating costs. The 35kV and 20kV power supplies directly enter the power consumption center, effectively improving the reliability of the power supply.

Features

The SC(B)10 series 20kV class and 35kV class non-exciting voltage regulating dry type transformers produced by our company are low-loss products, which meet the requirements of national standards GB6450, GB/T10228 and IEC726, and have the following characteristics:

● High performance, low loss, and a replacement for the 9 series.

● Select high-quality silicon steel sheet, and greatly reduce the magnetic flux density, reduce the amount of magnetostriction of the silicon steel sheet during operation, and effectively reduce noise.

● Optimize the structure of the high-voltage coil, improve the distribution of voltage and capacitance between the layers, greatly improve the product's ability to withstand the atmospheric overvoltage and operating overvoltage, and also improve the electric field distribution, so that the product volume is further reduced.

● The temperature control system and air-cooling device can be configured to automatically start the fan cooling device when the load is too large, which can effectively improve the overload capacity of the equipment.
