Ndi voteji wogawira Kodi

voteji dividers ankagwiritsa ntchito zamagetsi chifukwa cholola njira mulingo woyenera kuthetsa vuto la lamulo voteji. Pali njira zosiyanasiyana zojambula ku losavuta, monga ena magetsi pakhoma, kuti mokwanira zovuta kuloza ulamuliro matabwa normalizers windings wa mains voteji.

Kodi voteji wogawira? Chiphunzitso yosavuta - ndi chipangizo kuti, malingana ndi chiŵerengero HIV (kukhazikitsidwa payokha) akulamulira linanena bungwe voteji wachibale athandizira.

Kale mu masitolo Kawiri kawiri mutha kupeza nyali, khoma nyale, anaikira nyali ziwiri. Mbali yache ndi nyali okha zinalengedwa ntchito ndi voteji 127 volts. Dongosolo lonse chikugwirizana ndi banja zitsulo ndi mphamvu 220 ndipo anamuthandiza bwino. Palibe zozizwitsa! Chinthu njira ya kulumikiza ochititsa anapanga kanthu koma monga wogawira voteji. Tiyeni kukumbukira chiphunzitso zofunika magetsi, ndicho kufanana ndi siriyo kugwirizana ogula. Monga amadziwika, mu yotsatana mode kusinthitsa amperage ofanana, komanso kusintha voteji (malamulo timakumbukira Ohm a). Choncho, chitsanzo ndi yofanana nyale babu ogwirizana mu nkhani, amene amapereka kuchepetsa mwa kundipatsako kwa voteji nthawi awiri (110). Komanso voteji wogawira angapezeke mu chipangizo, kugawira mbendera ku mlongoti wina ndi ma TV angapo. Ndipotu, zitsanzo.

Tiyeni tione voteji wogawira yosavuta pa maziko a resistors awiri R1 ndi R2. Fundo chikugwirizana mu nkhani pa mfundo kupezeka aziwapatsa athandizira voteji U. Kuchokera mpaka pakati wochititsa kulumikiza resistors, pali linanena bungwe zina. Ndiko kuti, akutembenukira malekezero atatu, awiri - ndiwo malo Link (pakati pa mtengo okwana voteji ndi U) ndi chiyerekezo kupanga U1 ndi U2.

The mawerengedwe a wogawira voteji, ntchito malamulo Ohm a. Popeza Ine = U / R, U ndi mankhwala a pano pa kukana. Choncho, m'dera R1 ndi voteji ndi U1, pamene R2 kukhala U2. Panopa ndiye wofanana (siriyo kugwirizana). Popeza malamulo akuluakulu wathunthu, tikuona kuti chakudya ndi Uwerenge U U1 + U2.

ndi apano pansi pa zikhalidwe izi chiyani? Generalizing anthu aone kuti pali, ife kupeza:

Ine = U / (R1 + R2).

Kuyambira tikhoza kudziwa kufunika kwa voteji (U kuchoka) pa linanena bungwe la wogawira (izi zimakhala U1, ndi U2):

U kuchoka = U * R2 / (R1 + R2).

Pakuti dividers ndi resistances chosinthika pali zina zofunika ayenera kuwaganizira pa siteji ya Pamudzi, ndipo ntchito.

Choyamba, njira izi sangathe ntchito kusintha voteji ogula wamphamvu. Mwachitsanzo, mu njira iyi sikutheka mphamvu galimoto magetsi. Chimodzi mwa zifukwa - ndi resistor amaona okha. Fundo kilowatts ngati alipo, ndi zipangizo chachikulu dissipating gawo chidwi mphamvu monga kutentha.

Kulumikizitsidwa katundu kukana phindu sayenera zosakwana kulimbikira magetsi a circuitry wa wogawira, mwinamwake ayenera recalculate dongosolo lonse. Choncho kusiyana wogawira R ndi R katundu ayenera aakulu ngati nkotheka. Nkofunika molondola kusankha khalidwe R1 ndi R2, kuyambira zipembedzo kwambiri zikuphatikizapo kwambiri voteji dontho, ndipo overheat otsika kwambiri, kuwononga mphamvu ndi magetsi.

Kuwerengetsera wogawira zambiri anasankha mtengo wa nthawi yake zikusinthira (mwachitsanzo, 10) ndiye wamkulu kuposa zikugwirizana katundu amperage. Komanso, podziwa pano ndi voteji, kulimbikira amaphatikizidwa ndi kuchita masamu (R1 + R2). Komanso magome lotsatira anasankha mfundo muyezo R1 ndi R2 (polingalira awo amatha mphamvu akuchitira kupewa Kutentha kwambiri).
