Sei kuverenga pamusoro magetsi mutoro

Asati mberi magadzirirwe electrics mumba mako, furati, yokurenda, unofanira kutanga kugadzira kukarukureta zano, izvo zvichaita kuti dzakanyorwa ose kutarisirwa mutoro pamusoro panzvimbo, uyewo kureba nomumwe zvikamu waya. Kubudisa kadhi yakadaro uye unofanira kuverenga magetsi mutoro. Correct zvemagetsi redunhu rinoumbwa chinhu Ichatakura tambo uye netambo paidiwa zvikamu. Muzviitiko uko waya muchinjikwa-chikamu shoma pane inodiwa yacho chakaipa functionality kuti injini yakakwirira simba netambo anotanga overheat. Uye sezvo Somugumisiro ndiko kuparadzwa kuputira. Somugumisiro, nguva hwokushanda uye rakavimbika wiring rukoko iri yekudyidzana ipfupi. Uyezve, waya overheating kunogona kukonzera moto. Zvakadarowo kuitika kazhinji apo varimi (kuponesa) unoshandiswa waya chikamu, idukusa kunodiwa. Zvinoguma pfupi redunhu uye moto. Ngationei, chii chiri kuverenga pamusoro magetsi mutoro.

Yakarurama kusarudza nokuchinja mano uye waya muchinjikwa-chikamu kunobva siyana netsika parameters ose magetsi network. Chinonyanya kukosha kwavari remagetsi mutoro. Nemagadzirirwo Danho yakanatsa mari inogona vakatsunga vachingoshandisa kwemasvomhu nzira. Zvinonzi sechinhu chinokosha chaizvo kukarukureta pamusoro nemagetsi mitoro mu-danho matatu network, somunhu mutoro wavo igadzikwe zvakaenzana pakati maitikiro, kudzivisa kukanganiswa voltage. Zvisinei, mune mudzimba network kukarukureta kwakadaro kunofanira kuitwa pamasikiro kwete chete nhovo asiwo dzinogarwa.

Electrical mutoro kukarukureta rinoitwa kuti kuvazivisa tsika simba magetsi mano, hunhu mitoro yacho uye mains voltage. kushandiswa payakavakirwa nokuti Pakusarudza mutoro pari nokuda kuroora-danho network: I = P / (U × cosφ), apo:

• U - kukosha chairo romugove voltage (akayera mu volts);
• cosφ - runoenzanirana simba chikonzero.

For -danho matatu network dzemaitirwe kuti magetsi mitoro rinoitwa maererano mutoo: I = P / (1,73 × U × cosφ).

Zvichienderana hunhu mutoro simba chinhu ukoshi anosarudzwa. Munguva Masvomhu iri reactive mutoro mukuru simba (chinovhunga chiedza, dzemagetsi Motors, transformers nezvimwe nomoto.) Average ukoshi atora cosφ = 0,8. Pakusarudza simba ano nokuti basa mutoro (hita okunze, incandescent rambi) simba chakaita anenge kuenzana mumwe. Zvisinei, chero resistive mutoro dzose reactive zvinoriumba aripo, saka Masvomhu kushandisa ukoshi cosφ = 0,95.

In mhedziso, tikayeuka kuti magetsi asingakanganwiri zvikanganiso, hazvina kupa wechipiri mikana. Safety uye rakavimbika nemagetsi hurongwa - unotsvaka chero nyanzvi magetsi. Uye zvisinei kwaakanga anoshanda: kubasa kana iri private zvekutepfenyura. Electrical mutoro - ichi ndechimwe chezvinhu zvinokosha zvakagadzirwa parameters kuti inofanira kukurukurwa chero hurongwa.
