Product Description
Product Introduction
SC(B)14-10kV series epoxy resin cast dry-type power transformers can be used as the replacement products of oil-immersed distribution transformers. It is a product with excellent neutral performance of various dry-type transformers, especially suitable for urban power grids, high-rise buildings, Business centers, theaters, hospitals, hotels, tunnels, subways, stations, docks, airports, underground power stations, laboratories, combined substations and other important places.
Model and meaning
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 12mm 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.
Note: IP23 shell will reduce the cooling capacity of the transformer, the small capacity of about 5%, the large capacity of about 10%.
Performance characteristics
The temperature control system consists 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, and it will 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.
The temperature control and temperature display system can be installed at a certain distance from the main body of the transformer, and the lengths of the temperature measurement element leads are respectively:
Temperature control:<20m
Temperature display:<10m (two-wire system)
<100m (two-wire system with compensation conductor)
