Mene ne Mutu Multi-Pulse Rectification: Bude Aikin Transformers na Rectifier na Phase-Shifting?

A cikin saman na al'ada na iya, alaƙa don inganci, inganci da kwayoyin inganci na yawa kar zai fi hada. Ta hanyar kuma a cikin inverter na ɗaya zuwa na yawa, mazabar suna nufin halin da ba za su karɓi al'ada ba kuma su rero ingancin aikace-aikacen. Wannan shine abin da za a iya amfani da rectification na mitu da karkashin rectifier transformer zai zama zaɓin maza da za su yi a cikin wuri mai inganci.

Tsarin rectifier na biyu na ƙarƙashin, amma a yayin da aka yi amfani da shi girman, shine ainihin da ke cikin ƙarin na harmonics, wanda zai iya kama da zafi, alaƙa ɗaya mai ƙarfi, da kuma tsohon cikin alamun elektronik daga ciki. A wani irin rectifier transformer mai nufin nisa, amma ya ba da halin da ke ƙasa ta hanyar fitowa da yawa—saboda 12, 18, ko kuma 24 pulses. Ta hanyar ƙara wasu secondary windings da nisa na musamman, wanda ya sake gudanar da harmonics na ƙarƙashi, ya zama dalibin da ke ƙasa da karkara. Wannan ya sa shi ya zama mahaiffa a cikin masana'anta da ke ƙasa da nafti, gine, takurduwa, da kuma masana'antun girma, inda kowane abu da za a iya amfani da ita shine wajib din da ke cikin kusurwa.

Amma yaya ne a cikin haka ake amfani da shi? Wani ne mai ba da shidda waje akan kowane rectifier bridges da suke samun input daban-daban na phase angles. Misali, a 12-pulse system ya ke amfani da 30-degree phase shift a tsakanin biyu set na six-pulse bridges, wanda ya kara rage 5th da 7th harmonics da zai zama domin a tsarin mace. Ana kirkira Yanzu na Phase-shifting rectifier ta hanyar tashin tare da tattara tare da ma'ajin wanda ke samar da shifts, kaurawa da yare-yaren Yanbian triangle method don samar da balanced phase displacement ba tare da samu daidaitan voltage symmetry ba.

Wannan tsari ba ta hanya ƙaddamar da kari na waveform ba, amma ta kuma kashe girman da kuma farashin abubuwan da ake amfani da su don filtering. Wasu al'ada da ke amfani da multi-pulse rectifiers suna fahimci rane na kasa da transformer heating kuma suna sami ƙarancin cikin inverter, saboda mai girma na harmonic. Daga bincin tsari na jama'a, wannan yana nufin kasa da kara mai girma na al'ada, farashin da ke cikin alamun tura, kuma kadau da al'adu da suka shafi grid codes masu alaƙa da kari na aiki da kuma total harmonic distortion (THD). A wani motsa, ba ta hanya mai girma na teknologi ba - ta hanya keɓanƙe a cikin sa'adatin tsarin aiki.

Don hanyar aikace-aikacen da ke da yawa ko kai tsakanin da zane-zane na voltage da zai iya samar da alaƙa mai kyau, za a mutuwa ne don zaɓar tsari na transforma da dace. Rectifier transformer na phase-shifting batake nufin kawo specs ba—balaye yawan masu iyakawa. Sai dai idan babu aiki daga cikin, kamar yadda wajen karkashin ko rig na offshore, waɗannan masu iyakawa su dace. Shine wani ilan waɗannan abubuwan da mutane da suka yi aikinmu masu amfani da an cinyar da multi-pulse domin kawo suwa masu iyakawa da suke buƙata, kuma batake suyi amfani da abubuwan da ba daidai ba.

A matsayin masana da ke da amfani da yawan kama da kungiyar amince, muna fahimci watsa daga cikin tasho da tattara da ke tsakanin inganci da kai'ido. Kowane daya daga cikin transformer na rectifier na phase-shifting da muke nufin, bata kai'ido ne a al'adun karkashin amfani da elektiriki kuma an rarraba su don yawan gudun da kai'ido na al'ada a kansa. Idan kake ninka sanyi wani al'ada mai tsoho ko kake taka leda wani sabon a kansa, iskar da suwar transformer na rectifier multi-pulse mai iya amfani a kansa na iya amfani da shi zai ba da inganci mai tsawo wanda zai tafiya daga cikin al'adun bayanai.

A cikin sadarwa da ke da aladuƙa da kari da kari na alaka waje, rectifier transformer na phase-shifting batake abin da aka yi ba—balaye tsofaffin tacewa. Tuntu ɗin mu yau domin samun sauti yadda waɗannan abubuwan da suke da sauti na mu za a iya ƙarin aikinmu ta hanyar amfani da technology da aka buƙata da taƙaddun da kawai abokin faburiken da ya yi lafiya zai iya kawo.
