SCB series dry type transformers refer to transformers in which the core and windings are not immersed in insulating oil. The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When natural air cooling, the transformer can run continuously for a long time under the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50% in short time. It is suitable for intermittent overload operation or emergency accident overload operation; due to the large increase in load loss and impedance voltage during overload, it is in an uneconomic operation state, so it should not be kept in continuous overload operation for a long time.

Dry Type Power Transformer Features:
Since epoxy resin is a non-flammable, flame-retardant, self-extinguishing solid insulating material, safe and clean, epoxy resin cast dry-type transformers are oil-free, non-flammable, and have low operating loss, strong short-circuit resistance, less maintenance work, high working efficiency, small volume and low noise. It is often used in places with high performance requirements such as fire prevention and explosion protection, and has the following practical characteristics:
1.It is safe, fireproof, pollution-free, and can be directly operated in the load center;
2.High mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life;
3.Low loss, low noise, obvious energy saving effect, maintenance-free;
4.Good heat dissipation performance, and capacity operation can be increased in short time when forced air cooling;
5.Good moisture resistance;
6.Dry-type transformers can be equipped with a complete temperature detection and protection system. Using intelligent signal temperature control system, it can automatically detect and display the respective operating temperatures of the three-phase windings, can automatically start and stop the fan, and have functions such as alarms and trips. IS485 communication interface can be installed to realize wireless detection and intelligent management.
7.Small size, light weight, less space and low installation cost.
Dry Type Power Transformer Standard:
IEC60076, GB/T1094.11, GB/T17211.
Dry Type Power Transformer Applicable Environment:
1.0-40 (ºC), relative humidity <70%;
2.Altitude: no more than 2500 meters;
3.Avoid rain, humidity, high temperature, high heat or direct sunlight.
4.Prevent working in places where there are more corrosive liquids, or gases, dust, conductive fibers or metal fines;
5.Prevent working in vibration or electromagnetic interference places;
6.Avoid long-term storage and transportation upside down, and avoid strong impact.
