Takaitaccen Meters na Induction

Meters na induction suna watai da ake amfani da su don kawo yawan energy na electricity a tashar mutane da kuma al'adu, ta haka tare da amfani da mu'amala masu fluxes da currents na alternating.

Siffar Tattalin Noma

Siffar tattalin noma da tattalin biniya ga meters na induction shi ne musamman da dace da fahimta, wanda ya zama babban abin da ake amfani da shi don kawo yawan energy a tashar mutane da kuma al'adu. A cikin duk meters na induction, an samun biyu masu fluxes da za a yi da currents na alternating na disc na metal. Wannan fluxes na alternating suna haɓaka emf na induced. Wannan emf yana mu'amala da current na alternating a gaba, wanda ya haɓaka torque.

Duk da haka, emf na inda biyu yana mu'amala da current na alternating na inda daya, wanda ya haɓaka torque a gaba. Wannan torques na mafi yawa suna haɓaka disc na metal zuwa.

Wannan shine siffar tattalin noma na meters na induction. Idan bayan nan, za a rubuta takaitaccen expression na deflecting torque. Za a iya cewa flux na inda daya shine F1 kuma flux na inda biyu shine F2. Don haka, amsa mai tsawonta na biyu masu flux suna rubutu a haka:

Amsa, Fm1 da Fm2 suna cikin maximum values na fluxes F1 da F2, B shine phase difference bayan biyu masu fluxes. An zama rubuta takaitaccen expression na induced emf’s na inda daya da inda biyu.

Amsa, K shine constant kafin f shine frequency. Za a yi diagram na phasor da aka tabbatar F 1, F2, E1, E2, I1 da I2. Daga diagram na phasor, ita ce I1 da I2 suna lagging behind E1 da E2 da angle A.

Angle bayan F1 da F2 shine B. Daga diagram na phasor, angle bayan F2 da I1 shine (90-B+A) kuma angle bayan F1 da I2 shine (90 + B + A). Don haka, za a rubuta takaitaccen expression na deflecting torque a haka, kuma expression na T d2 shine

Torque na total shine T d1 – Td2, idan bayan an substitute value na Td1 da Td2 da kuma an sauyi expression, muna samu

Abubuwan Meters na Induction

Biye na abubuwan meters na induction suna single phase da three phase meters na induction.

Wannan shine takaitaccen expression na deflecting torque a cikin meters na induction. Idan bayan nan, akwai biye na abubuwan meters na induction, kuma suna rubuta a haka:

• Single phase type

• Three phase type meters na induction.

Kompoonentoci Meters na Single Phase

Kompoonentoci na biye shine driving system da electromagnets, disc na aluminum na floating a moving system, braking system da permanent magnet, da kuma counting system don record revolutions.

Farkoci

• Sun mayar da moving iron type instruments a cikin price.

• Sun mayar da high torque is to weight ratio a cikin wasu instruments.

• Sun mayar da accuracy a cikin temperature da loads na wide range.
