Dîwarên Toroidal vs Square: Dîtimên Nîşanî
Toroidal Transformer Nedîne û Çi Ye?
Transformator toroidal yek tîpa sereke yên transformatorên elektronîk e ku çimkaniyê di ser anîna ve destpêkirî û digelîn tekmîlên elektronî de bikar îstendin. Têmîn kirina nîşanên wekî transformatorê guhertina dema û transformatorê izolasyonê hene. Derve, transformatoran toroidale bi serîya tam dabeşandin û bi rêjiyê da li ser komputeran, pîçeyên medî, telekomunikasyon, alatên mesele, û çalakirinê hatîn bikar îstendin.
Li Çîn, transformatoran toroidale ji sifir bêtirin derketin û li ser piramerdanê ya parzûnda heye. Hemî ew ê niha neteweyên navendîya hilbijartin û hemî ew ê bi miqdarên mezin eksport kirin. Di navend de, ew ê peyser li ser anîna ve destpêkirî yên evdil, alatên kontrol automatîk, û rojnameyên kvarcî û digelîn anînên din bikar îstendin.
Taybetmendiyên Transformatoran Toroidale
Efficyency elektrîkî ya bilind: Kerk nekî şerên hewa tune û faktorê stacking dibe li ser 95%.
Vibraçîyon û zangînî ya nikî: Absence of an air gap in the core reduces vibration-induced noise. The windings are uniformly and tightly wrapped around the toroidal core, effectively minimizing the "humming" sound caused by magnetostriction.
Deraja ya kamîn a xilas: Core loss can be as low as 1.1 W/kg, resulting in minimal iron losses and low core temperature rise. The windings dissipate heat well on the relatively cool core, leading to low overall transformer temperature rise.
Rastîna rakan: Yek bolt central yekemî transformator toroidal hane, ew ê bêtir bike rastîna û rakirina raxta bêtir bike di alatên elektronîk de.
Ji Bo Difference Between Toroidal Transformers and Square (Laminated) Transformers
Hemî transformatoran toroidale û square transformers jî tîpa sereke yên transformatorên elektronîk ne. Binnî, transformatoran toroidale forma halqa hene, kerkên bi rerolling silicon steel sheets dibêjin, herêmekî square transformers E-type û I-type silicon steel laminations stacked alternately to form the core. Ji bo differences in physical structure, what other distinctions exist between them?
Efficiency: At the same power rating (e.g., 50W), a toroidal transformer achieves an efficiency of 86%–90%, while a square transformer operates at 80%–84% efficiency.
Temperature rise: At the same power (e.g., 50W), toroidal transformers exhibit much lower temperature rise compared to square transformers, which run hotter.
Cost: For power ratings above 200W, toroidal transformers are lower in cost, whereas square transformers become relatively more expensive.
Electromagnetic interference: Toroidal transformers have very low leakage flux, while square transformers exhibit noticeable leakage flux and generate low-frequency interference.
Service life: Although neither type uses materials that significantly degrade over time, toroidal transformers generally offer a longer service life.
Low-temperature performance: Toroidal transformers can operate normally at temperatures as low as -30°C, making them well-suited for outdoor use in northern winters.
Design flexibility: The size of toroidal transformers can be customized according to customer requirements. Multiple windings can also be tailored to specific needs without requiring molds, and installation is convenient.
