Ngatitarisei sei kuitika kukarukureta rinoitwa pasi simba

Asati mberi magadzirirwe magetsi mumba mako, unofanira kugadzira muripo zano pamwe rairatidza akatangira mitoro pamusoro panzvimbo uye kureba nomumwe zvikamu waya. Kuronga zano kudaro uye kudiwa kuverenga "simba" pamusoro ano. Rairira Mapping zvemagetsi musha Ichatakura anodiwa zvikamu netambo kuti achadzivirira wiring yako kubva overheating uye, naizvozvovo, zvingangoita moto. Ngationei, asi chii chiri kuverenga ye "simba" pamusoro ano.

Kwakakodzera pakusarudza nokuchinja mano uye waya muchinjikwa-chikamu kunobva siyana netsika parameters ose magetsi network. Chinonyanya kukosha pakati pavo remagetsi. Uye panguva padariro mazano tsika izvi zvinogona chete totsunga pedyo kwemasvomhu kukarukureta. Zvikuru anonzi ari "simba" pamusoro kuitika kukarukureta mu-danho matatu network, apo mutoro inofanira kuiswa zvakaenzana pakati maitikiro, kudzivisa nokumonyaniswa. Zvisinei, mune mumaguta dzinogarwa network, Masvomhu izvi yaifanira pamasikiro kwete chete nhovo asiwo dzinogarwa.

"Simba" kukarukureta ano anopiwa zvemagetsi simba anozivikanwa tsika, hunhu zvinorema nerubatsiro voltage. Nokuti chete-danho mains uchishandisa mutoo: I = P / (U × cosφ), apo:

• U - chaiko voltage ukoshi unotaurwa volts;
• cosφ - runoenzanirana simba chikonzero.

Zvichienderana hunhu mutoro simba chinokonzera anosarudzwa. Saka, nokuti basa mutoro (hita okunze, incandescent marambi) zviri anenge kuenzana kubatana. Zvisinei, kana iwe funga kuti ari resistive mutoro dzose reactive pakuderedza, saka kuverenga kwakakurumbira kushandisa kukosha Kosi, zvakaenzana 0.95. Kana mutoro kukarukureta, iyo inozivikanwa nokuva yakakwirira nesimba reactive (chinovhunga chiedza, dzemagetsi Motors, induction chamatare, nomoto transformers , etc.) Kuendeswa Zvichakadaro ukoshi cosφ, akaenzana 0,8.

Nokuti nzira-danho AC simba romugove vachava zvinotevera chimiro: I = P / (1,73 × U × cosφ).

For-danho matatu network simba chakaita kuti basa uye reactive mitoro vari zvachose kufanana chete-danho network.

Saka, achishandisa pamusoro Masvomhu zvakafanira kuti kuitisa Masvomhu vose simba netsapo Magetsi tsika, kushandiswa pane imwe nzvimbo.

Inotevera pavaipfuura Masvomhu edu, kuchava pakusarudza waya muchinjikwa muchikamu. Kunyange zvazvo michina mabhuku anogona kazhinji kuwana chinhu zvakadai "kukarukureta simba wire" Chokwadi, hazvina akaverenga, asi achiri "yakasarurwa". Under kunzwisisa kukarukureta payakavakirwa kuti kuona mumwe mutoro kuitika pamusoro. In pamberi zvimwe tsika kuitika uye voltage wire muchinjikwa chikamu anosarudzwa kubva tarirai-matafura. matafura ava kutarisana chaizvo uye regai zvinoda rondedzero. Iwe tanga kusarudza waya zvinhu: mhangura kana aruminiyamu, uye ipapo pomugove voltage uye kukosha magetsi paanenge pakutsvaga waya muchinjikwa chikamu.

Pano, chaizvoizvo, isu akatarisa sei kuverenga zvemagetsi mutoro uye vakasarudzwa-chikamu muchinjikwa ari netambo kuti magetsi muzvirongwa.
