Ukuba ingxaki yangoku ye-shaft isonjululwe, ukhuseleko lwenkqubo enkulu yokuthwala imoto iya kuphuculwa ngokufanelekileyo

Injini yenye yezona matshini zixhaphakileyo, kwaye sisixhobo esiguqula amandla ombane abe ngamandla omatshini. Ngexesha lenkqubo yokuguqulwa kwamandla, ezinye izinto ezilula nezintsonkothileyo zinokubangela ukuba i-motor ivelise imisinga ye-shaft ukuya kumaqondo ahlukeneyo, ngakumbi kwiimotor ezinkulu, kwiimotor ezinevoltage ephezulu kunye neemotor frequency frequency, zininzi iimeko zokudinwa kwemoto kunye nokusilela ngenxa ishaft yangoku.

Iimeko eziyimfuneko zokuvelisa okwangoku zi-voltage kunye ne-loop evaliweyo. Ukuphelisa i-shaft yangoku, ukusuka kwindawo yokujonga i-theory, umlinganiselo omnye kukulawula okanye ukuphelisa i-voltage ye-shaft, kwaye enye kukunqumla i-loop evaliweyo; ekusebenzeni, abavelisi abahlukeneyo bajolise kwiimeko zokusebenza ezahlukeneyo, amanyathelo athathiweyo awafani. Kwiimeko zokusebenza ezilula ukusebenza, iibrashi ze-carbon diversion ziya kusetyenziswa. Umgaqo-siseko kukudala enye isiphaluka ukuhlula i-bearing from the circuit; kwiimeko ezininzi, oko Ngokwendlela yokunqunyulwa kwesekethe, sebenzisa imikhono yokufaka i-insulating, i-insulating end covers, i-insulating bearings, okanye imilinganiselo yokukhusela indawo yokuthwala.

Ukuze kuncitshiswe ngokusisiseko ingozi yangoku ye-shaft, ingqiqo yeskimu soyilo kunye nokuhambelana nenkqubo yokuvelisa kuyilo kubaluleke kakhulu. Ulawulo olubhinqileyo lwesikimu soyilo kunye nenkqubo yokwenziwa kwenkqubo inoqoqosho kwaye ithembekile kuneendlela ezahlukeneyo zamva.

I-voltmeters yombane (ekwaziwa ngokuba yi-AC millivoltmeters) ngokubanzi ibhekisa kwi-analog voltmeters.Sisixhobo sokulinganisa esisetyenziswa ngokuqhelekileyo kwiisekethe zombane. Isebenzisa intloko yamagnetic njengesalathisi kwaye ingokwesixhobo sokukhomba.I-voltmeter ye-elektroniki ayikwazi ukulinganisa i-voltage ye-AC kuphela, kodwa ingasetyenziselwa njengebhendi ebanzi, isandi esiphantsi, i-amplifier ephezulu.

Ii-voltmeters ze-elektroniki ngokubanzi zenziwe ngamacandelo amabini: ukukhulisa kunye nokufumanisa.Ubukhulu becala zenziwe ngamacandelo amane: i-attenuator, i-AC voltage amplifier, idetector kunye nonikezelo lwamandla olulungisiweyo.

Isixhobo sokulinganisa i-electronic voltmeter sisetyenziswa ikakhulu ukulinganisa iivolthi zesignali eziphezulu nezisezantsi, kwaye sesinye sezona zixhobo zisetyenziswa kakhulu kumlinganiselo wombane.

Amandla ombane alinganisiweyo athotywa kuqala yi-attenuator kwixabiso elifanele igalelo le-AC amplifier, emva koko inyuswe yi-AC voltage amplifier, kwaye ekugqibeleni ifunyenwe ngumtshina ukufumana umbane we-DC, kwaye ixabiso libonakaliswa yintloko yemitha. .

I-angle yokuphambuka yesalathisi se-voltmeter ye-elektroniki ilingana nexabiso eliphakathi lombane olinganisiweyo, kodwa iphaneli ilinganiswa ngokwexabiso elisebenzayo le-voltage ye-sinusoidal AC, ngoko ke i-voltmeter yombane inokusetyenziselwa ukulinganisa ixabiso elisebenzayo. yombane we-sinusoidal AC.Xa ulinganisa i-voltage ye-AC ye-non-sinusoidal, ukufundwa kwe-voltmeter ye-elektroniki akukho ntsingiselo ngqo. Kuphela ngokwahlula ukufundwa kwe-coefficient ye-waveform ye-1.11 ye-voltage ye-sinusoidal AC inokufumaneka ixabiso eliqhelekileyo lombane olinganisiweyo.

I-analog voltmeters ngokubanzi ibhekisa kwi-pointer voltmeters, eyongeza umbane olinganiselweyo kwi-ammeter yemagnetoelectric kwaye iyiguqulele kwi-engile yokuphambuka kwesalathisi ukulinganisa.Xa ulinganisa umbane we-DC, unokwandiswa ngokuthe ngqo okanye ukhuliswe okanye ucuthwe ukuze ube sisixa esithile se-DC yangoku ukuqhuba isalathiso sokuphambuka kwesalathisi sentloko yemitha ye-DC.Xa ulinganisa amandla ombane e-AC, kufuneka idlule kwi-converter ye-AC/DC, oko kukuthi, i-detector, ukuguqula umbane olinganisiweyo we-AC ube yi-voltage ye-DC elinganayo, emva koko ilinganise umbane we-DC.Ngokweendlela ezahlukeneyo zokuhlela, kukho iindidi ezininzi ze-analog voltmeters.

I-voltmeter yedijithali iguqula ixabiso lamandla ombane alinganisiweyo libe yi-digital quantity ngokusebenzisa iteknoloji yedijithali, kwaye emva koko ibonise ixabiso lombane elilinganisiweyo kumanani wedesimali.I-voltmeter yedijithali isebenzisa i-converter ye-A / D njengendlela yokulinganisa, kwaye ibonisa iziphumo zokulinganisa ngomboniso wedijithali.I-voltmeter yedijithali yokulinganisa amandla ombane e-AC kunye nezinye iiparamitha zombane kufuneka ziguqule iiparamitha ezilinganisiweyo zombane phambi kwesiguquli se-A/D, kwaye ziguqule iiparamitha ezilinganisiweyo zombane zibe ngumbane we-DC.

Voltmeters Digital inokohlulwa ibe voltmeters yedijithali DC kunye voltmeters AC digital ngokwezinto umlinganiselo ezahlukeneyo.I-voltmeters yedijithali ye-DC inokohlulwa ibe ziindidi ezintathu: uhlobo lokuthelekisa, uhlobo oludityanisiweyo kunye nodidi oluhlanganisiweyo ngokweendlela ezahlukeneyo zokuguqula i-A/D.Ngokwemigaqo yokuguqulwa kwe-AC / DC eyahlukeneyo, i-voltmeters yedijithali ye-AC inokwahlulwa ibe ziindidi ezintathu: uhlobo oluphezulu, uhlobo lwexabiso eliphakathi kunye nohlobo olusebenzayo lwexabiso.

I-voltmeter yedijithali isebenzisa imveliso yedijithali ukubonisa ngokubonakalayo iziphumo zokulinganisa. Ukongeza kwiingenelo zokuchaneka komlinganiselo ophezulu, isantya esikhawulezayo, i-impedance enkulu yokufaka, umthamo ogqithisiweyo oqinileyo, amandla okumelana nokuphazamiseka, kunye nesisombululo esiphezulu, kulula ukudibanisa kunye neekhomputha kunye nezinye izixhobo. Izixhobo zovavanyo oluzenzekelayo kunye neenkqubo zikwathatha indawo ebaluleke kakhulu kumlinganiselo wombane.
