Description
Product overview
10KV grade SC(B) series epoxy resin cast dry-type transformer can be used as an oil-immersed distribution transformer replacement product. It is a product with better performance in all kinds of dry-type transformers, especially suitable for urban power grids, high-rise buildings, business centers, hospitals, hotels, tunnels, subways, underground power stations, laboratories, stations, docks, airports, combined substations and other important places.
Product features:
The low-voltage coil is wound with foil, and the foil winding is cured into an integral structure through end sealing; the high-voltage coil is cast with epoxy resin in a vacuum state, and after curing, a solid long cylindrical whole is formed, with high mechanical strength, small partial discharge, and reliability High: resistance to short circuit and high level of lightning impact. The inner and outer resin layers of the coil are thin, and the heat dissipation performance is good. The cooling method generally adopts air natural cooling (AN). For transformers of any protection level, air cooling system (AF) can be configured to improve short-term overload capacity and ensure safe operation. Low loss, good power saving effect, economical operation and maintenance-free. Small size, light weight, small footprint, low installation cost, do not have to consider the oil tank fire suppression facilities and backup power supply.
Enclosure protection
The shell material is made of stainless steel or aluminum alloy. The protection class reaches IP20 and IP23. IP20 shell can prevent the diameter of more than 12.5mm solid foreign objects into the transformer for further safety protection. The IP23 enclosure also prevents the inflow of water droplets within an angle of 60 ° to the vertical line, and is suitable for outdoor operation.
The temperature control system is composed of a temperature controller and a PTC temperature measuring element installed on the hottest spot of the product, that is, the upper end of the low-voltage winding, to realize the temperature measurement and control of the transformer. If the temperature of the transformer winding is too high due to overload operation or fault, the temperature controller will send An alarm signal will automatically trip when the temperature exceeds the safe value. When forced air cooling is used, the temperature controller determines the input or switching of the cooling fan according to the winding temperature. The temperature display system directly displays the hot spot temperature of the winding during the operation of the transformer, and can be used in conjunction with the temperature control system.
