Top 25 Muhimmanci Taswirin Magana na Tashar Transformer

1). Me kuke so Transformer?

A transformer yana shafi aiki mai zama tushen elektrikin kasa daga wata wurin zuwa wurin mafi tsawo ko kuma mafi hankali baki daya da kullum ba a gaji masu faifai.

2). Kake ne kimiyyar tushen transformer?

Kimiyyar tushen transformer ta koyar da kimiyyar mu'amala na musamman. A wannan kimiyyar ke, mutanen magana suna haɗa waɗannan wurin elektriki biyu.

3). Mene ne ma'ana a cikin rating ta transformer?

Rating ta transformer yana nufin gaba-gaban karamin kasa da za su iya samun shi baki daya da tsari a kan kurkurun transformers ya sa sani ba a gaji masu faifai.

4). Yadda ake bayyana rating ta transformer da kuma mune bukatar?

Rating ta transformer ake bayyana a cikin KVA saboda haka. Rating ta transformer ana iya tabbatar da ita a kan tsari a kan kurkurun transformers ya sa sani.

Tsari a kan kurkurun transformers ya sa sani yana kasancewa da karamin kasa. Karamin kasa a kan kurkurun transformers ya sa sani ana iya tabbatar da ita a kan volt-ampere (VA) & ba a gaji power factor.

Idan karamin kasa na biyu ya sa sani, akwai I2R loss da ya sa sani.

Wannan loss yana rage karamin kasa. Power factor yana nuna karamin kasa a kan kilowatts. Idan power factor yana rage don karamin kasa na biyu, karamin kasa na biyu yana rage, kuma yana rage loss da tsari a kan kurkurun transformers ya sa sani.

Saboda hakan, transformers suna ake bayyana a cikin KVA ba KW.

5). Mene ne power factor ta transformer?

Power factor ta transformer yana rage da kuma lagta idan ba a kan karamin kasa. Amma, power factor a kan karamin kasa yana nuna power factor ta karamin kasa da ya sa sani.

6). A cikin transformer, mene ne phase difference da ake da shi a kan voltage da current a kan karamin kasa?

Akwai phase difference da current a kan karamin kasa ta transformer ta rage da voltage da 70.

7). Mene ne abubuwan da suka fiye a cikin transformer?

Abubuwan da suka fiye a cikin transformer sun hada da:

• Magnetic circuit made up of a laminated

• Iron core & clamping structures

• The primary winding

• The secondary winding

• An insulating oil-filled tank

• Terminals (H.T) with bushing

• Terminals (L.T) with bushing

• Conservator Tank

• Breather

• A vent-pipe

• Wind Temperature Indicator (WTI)

• Oil Temperature Indicator (OTI) and

• Radiator

8). Mene ne abu da ake zaɓe don iron core da kuma mune bukatar?

Ake zaɓe don laminates of specifically alloyed silicon steel (silicon ratio 4 to 5%) saboda hanyar electrical resistance, high permeability, non-aging qualities, and low iron loss.

9). Mene ne abu da iron core ya yi a cikin transformer?

A cikin transformer, iron core yana bayyana magnetic path da low reluctance.

10). Yadda ake rage magnetic leakage?

Ake rage magnetic leakage tare da sectionalizing and interleaving the primary & secondary windings.

11). Mune bukatar da iron core joints zai ci gaba?

Iron core joints zai ci gaba don rage air gap a cikin magnetic circuit, saboda air gap yana rage magnetic flux saboda high resistance.

12). Mune bukatar da power factor ta transformer yana rage da kuma lagta idan ba a kan karamin kasa?

Current ta transformer yana da biyu components. Magnetizing current (Im) in quadrature (900) to the applied voltage & in phase current in phase with the applied voltage. 

Majority of the excitation current received by the transformer from the primary winding under no-load conditions is used to magnetize the path.

As a result, the excitation current drawn by the transformer during no-load conditions is largely made up of magnetizing current, which is employed to generate a magnetic field in the transformer circuits (inductive nature). 

As a result of the inductive nature of the load, the power factor of the transformer during no-load conditions will be in the range of 0.1 to 0.2.

13). Mene ne zai faru idan ake amfani da DC supply a cikin transformer?

Idan ake amfani da DC supply a cikin primary winding ta transformer, ba ake faru back EMF.

Back EMF yana da muhimmanci saboda yana rage current generated by the machine. 

Idan ba a gaji back EMF, transformer yana faru massive currents, kuma yana rage primary winding ta transformer da ya sa sani. 

Sannan, idan ake amfani da direct current supply a cikin transformer, primary windings zai rage.

14). Yadda ake faru maximum efficiency ta power transformer da distribution transformer?

Idan core losses ta transformer sama da copper losses, transformer yana faru maximum efficiency a kan load factor (α).

PCopper loss = α2X PCore loss

Optimum efficiency ta transformer yana faru idan core loss sama da copper loss using the above calculation for a specific load factor (α).
