Transformatorët e shpërndarjes, tre-fazore, 50 Hz, të tipit të thatë, nga 100 deri në 3 150 kVA, me tensionin më të lartë për pajisjet që nuk e kalon 36 kV - Pjesa 1: Kërkesa të përgjithshme

Three phase dry-type distribution transformers 50 Hz, from 100 kVA to 3 150 kVA, with highest voltage for equipment not exceeding 36 kV - Part 1: General requirements

Asnjë informacion i shtuar.

This European Standard covers dry type transformers from 100 kVA to 3 150 kVA intended for operation in three phases distribution networks, for indoor continuous service, 50 Hz, natural cooling, with two windings: − a primary (high voltage) winding with a highest voltage for equipment of 3,6 kV to 36 kV; − a secondary (low voltage) winding with a highest voltage for equipment not exceeding 1,1 kV. For outdoor application, special design or enclosure (enclosure with adapted IP and IK degrees protections) should be requested. NOTE 1 This European Standard may be applied, as a whole or in part to transformers having windings with more than one rated voltage. In this case the rated power for each coupling ratio should be specified by the purchaser. NOTE 2 For dry type transformers installed in power generating plants, additional requirements, not covered by this European Standard, and alternative requirements may be specified. NOTE 3 For dry type transformers dedicated to wind turbines applications additive requirements are specified in EN 60076-16. The object of this European Standard is to lay down requirements related to electrical characteristics, dimensions and designs of three phases distribution dry type transformers. These transformers should be in accordance with EN 60076-11 for general requirements.
