Dry transformer is our company introduced foreign advanced technology, independently developed SCB10, SCB11 series of thin insulation dry transformer with packing, because the coil is wrapped by epoxy resin, so non-combustible, fire, explosion-proof, maintenance-free, pollution-free, small volume, can be directly installed in the load center. Scientific and reasonable design and pouring process at the same time, make the product less partial discharge, low noise, heat dissipation ability, under the condition of forced air cooling can be long running under 125% rated load, and is equipped with intelligent temperature controller, a fault report *, overtemperature *, overtemperature tripping and brake function, and are connected to the computer through RS485 serial interface, Monitoring and control can be centralized. According to different use environment, can be equipped with different protection level shell or no shell, suitable for high-rise buildings, commercial centers, airports, tunnels, chemical plants, nuclear power plants, ships and other important or special environment places.
Voltage level 10-35kV, transformer capacity SC10, SCB10-3 ~ 2500kVA, the transformer is my company in digestion and absorption of imported technology based on the development of 35kV class insulation dry transformer, product design and manufacturing meet IEC60076, GB6450, GB/T10228 and other standards, The products are widely used in electric power plants, power stations, industrial and mining enterprises, user distribution power stations and other power and distribution systems, the product has the following characteristics:
(1) low loss, fully meet the standard requirements of **9,10,11 series of products and the requirements of ** energy-saving standards;
(2) small local discharge;
(3) Insulation grade reached F level, temperature resistance 155℃, the actual operation temperature rise is low, overload capacity is strong, in the case of self-cooling can be long-term 120% overload operation, in the case of forced air cooling can be 150% overload operation;
(4) the noise is small, on the basis of the national standard decreased by an average of about 20dB;
(5) Reliable performance, safe operation, convenient maintenance, with the overall mechanical strength of high short-circuit resistance, strong resistance to impact over voltage performance, moisture-proof performance is good.
Conditions of use:
The operating conditions that meet the following requirements are normal operating conditions.
A. altitude
