Mai suna da tsarin hanyoyin?

Tsarin hanyoyin na transformer yana nufin inganci a matsayin alaka mai kyau daga adadin turn bayan primary da secondary windings ta transformer, wanda yake daidaitar da kyakkyawan hanyoyin voltage da transformer. Tsarin hanyoyin shine daya daga cikin abubuwan da suka fi sani a transformer kuma ana amfani da ita don bincike yadda transformer ya hanyar voltage daga input zuwa output.

Takardun

Tsarin hanyoyin ta transformer an takarda a matsayin tarihi masu adadin turns a primary winding N1 zuwa adadin turns a secondary winding N2:

Tsarin hanyoyin zai iya tabbatar da shi a matsayin voltage, domin haka, tarihi masu primary voltage V1 zuwa secondary voltage V2:

Abun

Booster transformer: idan N1<N2, tsarin hanyoyin n<1, primary voltage yana da kyautar da secondary voltage, domin V1<V2.

Step-down transformer: idan N1>N2, tsarin hanyoyin n>1, primary voltage yana da tsakiyar da secondary voltage, domin V1>V2

Isolation transformer: idan N1=N2, tsarin hanyoyin n=1, primary voltage yana da tsari da secondary voltage, domin V1 ya bar V2.

Siffar sadarwa

Siffar sadarwa ta transformers ta shafi kan hukumomin electromagnetic induction. Idan alternating current ya haɗa a primary winding, yana gina alternating magnetic field wajen winding. Wannan magnetic field yana haɗa a secondary winding kuma yana hanyar electromotive force (EMF) a secondary winding a bangaren Faraday's law of electromagnetic induction. Yadda akwai da induced electromotive force yana da tsari da adadin turns a winding, saboda haka:

Alaka da current

A cikin ƙarin hanyoyin voltage, transformers sun hanyar current. A bangaren hukumomin electromagnetic induction, primary current I1 da secondary current I2

Alakan da suka dace yana da shi a matsayin ƙarin hukumar:

Wannan yana nufin cewa idan transformer shine booster transformer, secondary current zai ƙara; idan shi shine step-down transformer, secondary current zai ci.

Alaka da power

A fannoni, input power ta transformer yana da tsari da output power (kare loss):

Matsayin sadarwa

Tsarin hanyoyin ta transformer yana da matsayin sadarwa masu yawan cuta, ciki har da amma ba:

•  Samun power: A cikin yanayin samun power, booster transformers sun amfani a matsayin karfin voltage don ƙara energy loss a samun line; Step-down transformers sun amfani don hanyar high voltage electricity zuwa low voltage electricity da take da kyau don domestic da industrial use.

• Dagashin power: A cikin system ta dagashin power, transformers sun amfani don hanyar voltage ta high-voltage grid zuwa voltage da take da kyau don amfani a local grid.

• Amfani na industry: A cikin yawan equipment na industry, transformers sun amfani don hanyar voltage ta grid zuwa voltage da take da kyau don sadarwa na particular equipment.

• Laboratory da research: A cikin laboratories, transformers sun amfani don gina specific voltages ko currents don hakilin labari.

Design da zaɓe

A lokacin design da zaɓe transformer, yana da abubuwan da suka bukata:

• Requirements na load: Zaɓe tsarin hanyoyin da take da kyau a cikin requirements na load don ƙara cewa output voltage ya da tsari da requirements na load.

• Level na voltage: Zaɓe transformer da take da kyau a cikin level na voltage ta power system.

• Capacity: Zaɓe capacity ta transformer a cikin maximum power requirements na load.

• Efficiency: Zabi efficient transformer don ƙara energy loss.

• Reliability: Zaɓe high-quality transformers don ƙara long-term stable operation.
