Uyini rheostat? Izinhlobo kanye Imisebenzi

Abantu ababeka axhunyiwe ngandlela-thile ne-physics, electronics, umsakazo, babhekana enjalo into njengoba rheostat. Kodwa abanye azange abe inkomba ngakho. Lesi sihloko sizodingida yini a rheostat, futhi yini kungcono ngoba.

Incazelo kanye Izinhlobo

Ngakho, rheostat - idivayisi ehlanganisa resistors eziningana kanye namadivayisi ngawo ezilungisiwe ukungawi zonke resistors kuhlanganisiwe.

Izinhlobo dimmers ancike enhlosweni yabo:

• Kube ashukumisa rheostats samanje, ukukhonza ukuqala motor AC noma DC.
• Okusimamisa Resistor kuyadingeka ukuze uqale kagesi motors isivinini nge zamanje njalo nomthethonqubo yayo.
• I isikebhe sizinze noma umthwalo Resistor - apharathasi kagesi for ukumuncwa amandla ngesikhathi isiqondiso oyifunayo generator noma umthwalo sokuhlolwa generator.
• Rheostat excitation edingekayo ukuze alawule samanje Windings kokuba AC imishini kagesi noma yamanje eqondile.

Material futhi Ukubandisa

Omunye izakhi eziyinhloko ukuthi ukucacisa isici design indaba ka okubandakanya rheostat. Futhi ngenxa yalesi sizathu ingahlukaniswa dimmers ku ngobumba, uketshezi, metal namalahle. Ugesi kule resistors iguqulwe ibe ukushisa, okumele etholakala kuzo. Ngakho-ke, i-rheostat kuyinto emoyeni futhi uketshezi indlu. Uhlobo lwesibili kungaba amanzi noma amafutha. Air uhlobo sisetjentiselwe kufundzisa nome ngusiphi rheostat ukwakhiwa. Lolu ketshezi kuphela insimbi, ngoba resistors zabo kukhona uketshezi ovikelekile noma acwiliselwa ngokuphelele kulo. Kuyadingeka kulokhu ukwazi ukuthi uketshezi esetshenziselwa Ukupholisa ngomoya, futhi kungaba ngisho uqobo kufanele selehlile noma emoyeni, noma uketshezi.

metal rheostats

Uyini rheostat metal? Kuyinto isici kokuba uhlobo air Ukupholisa ngomoya. rheostats ezinjalo ezivamile, ngoba kalula kakhulu ingashintshwa ukuze ezihlukahlukene izimo zokusebenza. Lokhu kusebenza kuzo zombili izici ezishisayo kagesi kanye, futhi nemingcele design. Abakwazi kwenziwe nge uhlobo wangenela noma eqhubekayo ukumelana noshintsho.

Inkinobho uyisicaba. It has oxhumana ezithathekayo ukuthi umba ku oxhumana fixed indiza efanayo. Labo oxhumana ukuthi musa ukuthutha, eyenziwe ngendlela nezikulufi kokuba flat amakhanda cylindrical noma uhlobo hemispherical ngesimo amapuleti noma amathayi, okuyinto okungadingeki i arc e umugqa owodwa noma emibili. Oxhumana oluhamba libizwa ibhulashi. It ingaqedwa ngumuntu isigwedlo noma nokuqaliswa kwalo hlobo.

Nokho kukhona ukwahlukana self-Aligning futhi nesamoustanavlivayuschiysya. Inketho zokugcina ngomklamo kulula, kodwa, njengoba kunjalo ngokuvamile sinqamukile loxhumana naye, akuphephile ukuyisebenzisa. The self-bakubheka loxhumana ezihambayo inikeza degree kunesidingo sokuthi ucindezele futhi ukusebenza eziqinile. Yingakho lolu hlobo ivamile.

Izinzuzo nezingozi nebubi ka ukushintsha flat

Izinzuzo ukushintsha flat-uhlobo zihlanganisa design elula, usayizi encane nge nabaningi izinyathelo, izindleko ongaphakeme, udlulisela, nokunqamula nokuvikela circuit control.

Phakathi nemiphumela ethile engathandeki ambalwa waphawula enganele usuke umthamo, usuke umthamo encane. Futhi ngenxa yokuthi ukungezwani encibilika phansi ngokushesha uya ibhulashi.

uwoyela Ukupholisa

Metal rheostats uwoyela-ukupholisa uhlobo ukushisa umthamo luyanda kanye nesikhathi Ukushisa ngenxa ezinhle uwoyela ukushisa conductivity. Lokhu kwenza kube nokwenzeka ukwandisa umthwalo ukusebenza yesikhathi esifushane neyezinto ukunciphisa ukusetshenziswa impahla kanye ubukhulu resistors rheostat.

Elements ukuthi afakwa amafutha, kumele abe indawo enkulu ebusweni ukuqinisekisa ukudluliswa ezinhle ukushisa. Uma elivaliwe uhlobo Resistor, akunandaba mqondo ukuzigcina kube uwoyela. ukucwiliswa Ngokusobala unika oxhumana Ukuvikelwa futhi resistors emiphumeleni yizici zemvelo. Oxhumana nabo uwoyela ezithothene kakhulu iqhaza. Lokhu inzuzo yalolu hlobo dimmers. Ngenxa Lubrication mhlawumbe ngaphezulu ngokucindezela koxhumana naye. Kodwa zikhona nemiphumela ethile engathandeki. Lokhu kukhuphuka kwemali ingozi yomlilo izingozi ukungcoliswa emagcekeni.

I rheostat kungenzeka lithathwa Isifunda Resistor variable noma potentiometer. Lokhu kunikeza ukulungiswa abushelelezi ukumelana futhi, ngenxa yalokho, ukulawulwa amandla wamanje kanye voltage kulesi sifunda. Avame elisetshenziswa laboratories.

ballasts rheostats

Rheostat kokuba isinyathelo ushintsho ukumelana, eyenziwe resistors kanye nedivayisi ukushintsha ehlanganisa yena, kusukela oxhumana fixed, oxhumana naye beya. Lapha kukhona drive.

Qala ukulawula dimmers kukhona izingongolo armature, okuyinto ixhunywe oxhumana isilungisiwe. Oxhumana ezithathekayo uvala futhi ivula ezingeni ukumelana, kanye nezinye izifunda okuyinto kulawulwa ngokusho rheostat. Actuator rheostat kungenzeka motor noma ngesandla. Yini leyo? Rheostat lolu hlobo kuthiwa esakazwa. Kodwa bokwenza lokhu design isatholakala. Le nombolo enkulu izintambo umhlangano nezingxenye zokuthola. abaningi Ikakhulukazi kubo excitation rheostat nge inani elikhulu izinyathelo.

Rheostat egcwele uwoyela, eyakhiwa idivayisi usuke kanye Resistor amaphakethe ezishumekwe ethangini bacwiliswa uwoyela. Amaphakethe aqukethe izakhi eyenziwe ngensimbi kagesi. Banamathele isivalo ethangini.

Idivayisi usuke has ukubukwa eksisi isigubhu kanye unamathele nalokho nge cylindrical ebusweni izingxenye ezixhunywe ngokuvumelana isikimu. oxhumana elilungisiwe, ezixhunywe izakhi Resistor ogibele kukajantshi isilungisiwe. Lapho eksisi sigubhu uzungeza idrayivu noma ligcina uthi lokuphotha luzungeza, labo izingxenye ekuvaleni fixed oxhumana nabo, oxhumana nabo ezithathekayo ekubeni. Lokhu kushintsha ukumelana kulesi sifunda.

Okungenhla ukucacisa ngokugcwele umbuzo, lokho kuyinto rheostat. Njengoba ubona, lokhu kusho into ebaluleke kakhulu, okuyinto kabanzi ahlukahlukene izifunda kagesi.
