There is a good explanation of knowledge Guangdong transformer recycling

There is a good knowledge to explain the recovery of a transformer Guangdong, Guangdong transformer recycled product performance standards: GB10228-2008 "dry type power transformers technical parameters and requirements" GB6450-1986 "dry type power transformers" (IEC-726-19) GB / T17211-1998 "dry type power transformer load guidelines" VDE0550 \ IEC204-1 \ GB5226-85 \ JB5555-2001 (control transformer) Second, Guangdong transformer recycling conditions: 1. The altitude does not exceed 1000m; (1000 meters customized) 2. the maximum ambient temperature of not more than + 40 ℃, the highest monthly average of less than + 30 ℃, annual average temperature of not more than + 20 ℃, the minimum temperature -5 ℃; 3. Relative humidity less than 95%; The ambient air does not contain corrosive metal and damage the insulation of the harmful gas or dust, can not use the transformer by water, rain and snow erosion; 5. No severe vibration and shock vibration. Two transformer coil turns, respectively N1 and N2, N1 is the primary, N2 is secondary. On the primary coil is an AC voltage, the electromotive force is generated across the secondary windings when N2> N1, its primary EMF than the applied voltage is even higher, such a transformer called step-up transformer: When N2
