Materialis Isolationis Transformatorum in Oleo-Immersis et Siccis T/F

Systemata Insulationis in Transformatoribus Oleo-Immersis

Insulatio maxime praevalebit ad windings alta tensio in transformatoribus modernis constat ex conductoribus encausticatis cum interlayer insulatio charta kraft. Busbars tensio parva possunt uti conductoribus nudis cum insulatio charta inter stratos. Notabiliter, involucrum chartae super busbar conductores gradu substituitur ab coating polymer syntheticus vel involucris textilium syntheticorum.

Adoptio filorum aluminii, busbars, et conductorum strip cum coating encausticus praebet proposita specifica pro manufacturis distributionis transformatorum: alumen sponte format stratum insulans oxide post expositionem aeris, quod removendum est vel mitigandum in omnibus punctis connectionis electrica.Superaddit, conductores aluminii gradus electrici sunt relative moli, proni ad fluxum frigidi et differentialem expansionem durante clamping mechanicam.Methodi splicing pro filis aluminii includunt sudationem vel crimping cum instrumentis specialibus quae penetrant encausticum et stratos oxide, dum claudunt oxygenem in areis contactus.Busbars aluminii possunt weldiri per TIG (tungsten inert gas) welding, vel cold-welded/crimped ad connectors cupri/aluminii. Connectiones bolted ad alumen molle factibilis sunt cum proper cleaning joint.

Materialia Insulationis in Transformatoribus Dry-Type

Windings transformatorum dry-type saepe sigillantur vel opertantur resina/varnish ad protegendum contra factoribus ambientalibus causantes degradatio. Media insulationis pro windings primaria/secondary categorizantur ut:

• Cast coils: Formati per vacuum casting resina epoxy pro superior resistencia corona.

• Vacuum-pressure encapsulated: Sigillata sub vacuum-pressure ad augmentandum integritatem insulationis.

• Vacuum-pressure impregnated (VPI): Paint insulation infiltrat windings sub vacuum-pressure pro coverage uniforme.

• Coated insulation: Coating superficie praebet protectionem ambientalem pro winding

Cast Coil

• Winding reforzatur vel collocatur in modum et castatur cum resina sub vacuum pressure.

• Encasement in solid insulation minimit niveles sonoris. Vacuum-pressure resin casting eliminat vacua quae causant corona.

• Systema insulationis solidi assecurat superior fortitudinem mechanicam et short-circuit, dum resistit umiditati et contaminantibus.

Vacuum-Pressure Encapsulated

Winding imbeditur in resina sub vacuum pressure.Vacuum-pressure encapsulation eliminat vacua causa corona. Winding praebet excellentiam fortitudinis mechanicam/short-circuit et protectionem contra umiditatem/contaminantes.

Vacuum-Pressure Impregnated

Winding permeatur cum varnish sub vacuum pressure.Impregnation praebet protectionem contra umiditatem et contaminantes.

Coated

Winding immerge in varnish vel resina. Windings coated praebent protectionem moderatam contra umiditatem/contaminantes pro ambientes standard.
