After the calculation, due to the different cooling, the current density is different, I finished a winding section 96.5mm ?, secondary winding section 1562.5mm ?
What are the specifications of the copper row? Another request for a transformer copper specifications table.
A general use of cable out, select 120mm2 line can be; second to use two 100 × 10mm copper, copper is to tin treatment. Copper specifications table recommended to find the national standard, see the copper discharge capacity and installation methods, after all, the transformer must be produced to meet the national standard.
Answer: no love language, all the text is boring.
Selection principle of transformer copper
Meet the load requirements;
Transformer corresponding to the rated current in accordance with 1.1 times the overload factor to consider;
To meet the safety distance, and components aligned;
Satisfy the dynamic stability.
Transformer copper selection considerations
The choice of copper can not just consider the current carrying capacity it also consider the maximum short-circuit current size, that is, consider the choice of a copper after the most short-circuit when the short-circuit current short-circuit the size of the current matching the size of the protection (that is, Relay protection value size).
