Ndeupi musiyano uripo pakati pecheni dzakavharwa uye dzakavhurika?

Magetsi anoyerera nepadunhu uye dunhu rinogona kudzorwa kuti rivhure nekuvhara sezvinodiwa.

Asi dzimwe nguva ikozvino inogona kuvhiringidzwa kana kuti pfupi pfupi inogona kuitika. Zvakare, kune nzira dzatinogona kushandisa nemaune cheni kuti ivhure kana kuvharwa. Kuti tinzwisise zvese izvi, isu tinofanirwa kuziva mutsauko pakati peyakavhurika uye yakavharwa loop.

Musiyano uripo pakatin kuvhura ndokuvhara dunhu nderekuti dunhu rakavhurika kana paine kutyora pane imwe nzvimbo munzira yayo inodzivirira kuyerera kwemagetsi. Inoyerera chete kana pasina kuputsa kwakadaro, i.e. kana dunhu rakavharwa zvachose. Tinogona kuvhura kana kuvhara dunhu ne switch kana kudzivirira mudziyo senge fuse kana wedunhu breaker.

Ini ndichatsanangura mutsauko uyu zvakadzama nemienzaniso nemifananidzo, uye ndozoratidza mimwe misiyano yekunzwisisa zviri nani.

Chii chakavhurika uye chakavharwa kutenderera?

vhura loop

Mudunhu rakavhurika, hapana magetsi anogona kuyerera kuburikidza nawo.

Kusiyana nedunhu rakavharwa, rudzi urwu rwedunhu rine nzira isina kukwana inovhiringidzwa kana kuputsika. Discontinuity inoita kuti ikozvino itadze kuyerera.

dunhu rakavharwa

Muchikamu chakavharwa, magetsi emagetsi anogona kufamba nawo.

Kusiyana nedunhu rakavhurika, rudzi urwu rwedunhu rine nzira yakazara pasina kukanganisa kana kutyora. Kuenderera mberi kunobvumira ikozvino kufamba.

Mifananidzo

Mumagetsi edunhu madhayagiramu, tinowanzoratidza chikamu chakavhurika uye chakavharwa chedunhu nemabhuraketi akakomberedzwa uye dot gobvu, sezvakaratidzwa mumufananidzo uri pasi apa.

Nzira yekuvhura dunhu rakavharwa uye zvinopesana

Seketi yakavharwa inogona kuvhurika, kana zvinopesana, dunhu rakavhurika rinogona kuvharwa.

Loop yakavharwa ingavhurika sei?

Kana iyo ikozvino inoyerera kuburikidza nekavha yakavharwa inokanganiswa, inova yakazaruka.

Dunhu rakavharwa rinogona kuvhurika netsaona kana, semuenzaniso, kuvhurika kunoitika pane imwe nzvimbo mudunhu nekuda kwetambo yakaputsika. Asi kuvhurwa kwedunhu rakavharwa kunogona zvakare kudzorwa nemaune kana nechinangwa nema switch, fuse, uye macircuit breaker.

Saka, dunhu rakavharwa pakutanga rinogona kuvhurwa newaya yakaputsika nekudzima mutsikidzi wedunhu kana fuse yakavhuvhuta kana kuti cheketi inotyora.

Ko dunhu rakavhurika rinova sei dunhu rakavharwa?

Kana ikozvino inotanga kuyerera kuburikidza nedunhu rakazaruka, rinofanira kuvharwa.

Dunhu rakavhurika rinogona kuvharwa netsaona kana, semuenzaniso, kubatana kunoitika pane imwe nzvimbo mudunhu nekuda kweiyo wiring isina kunaka kana pfupi pfupi. Asi kuvhurika kwedunhu kuvharwa kunogona zvakare kudzorwa nemaune kana nechinangwa nema switch, fuse, uye macircuit breaker.

Saka, dunhu rinotanga rakavhurika rinogona kuvharwa nekuda kweiyo wiring isiriyo, pfupi pfupi, switch iri kuvhurwa, fuse nyowani iri kuiswa, kana dunhu rinovhurwa.

Chii chinoitika kana dunhu richivhura kana kuvhara

Ini ndichakuratidza zvinoitika munyaya yechirongwa chekuvhenekesa chine imwe kana maviri switch.

Imwe Derailleur Chain

Dunhu rakareruka rine switch imwe chete inogona kungobatanidzwa munhevedzano nemutoro, senge girobhu remwenje.

Muchiitiko ichi, kushanda kwegirobhu rechiedza kunoenderana zvachose nekuchinja uku. Kana yakavharwa (yakabatidzwa), mwenje uchange wakabatidzwa, uye kana wakavhurika (wakadzimwa), mwenje unodzima zvakare.

Uku kurongeka kwemaseketi kwakajairika mumaseketi emagetsi epamusoro apo isu tinoda kuve nechokwadi chekuti mudziyo wakaita semota yepombi yemvura inodzorwa neshanduko imwe chete.

Circuit ine ma switch maviri

Iwo maviri-kiyi chirongwa zvakare ane anoshanda maapplication.

Chii chinoitika kana dunhu richivhurwa kana kuvhara zvinoenderana nekuti dunhu rakakwana here kana kuti harina kukwana uye kuti iri nhevedzano kana parallel dunhu.

Funga nezvedunhu rine ma switch maviri ari kumusoro uye pasi pematanho kudzora girobhu rimwe chete. Tafura iri pazasi inokurukura zvese zvingangoitika kune yega yega schema rudzi.

Sezvauri kuona kubva patafura iri pamusoro, ZVINO ZVINHU zvinochinja zvinofanirwa kubatidzwa (kana kuvharwa) munhevedzano kuti mwenje uuye. Kana imwe yadzo yakadzimwa kana kuti ese ari maviri akadzimwa, mwenje unodzima sezvo uchavhura dunhu.

Mudunhu rakafanana, IMWE chete yema switch inofanira kunge yakabatidzwa (kana kuvharwa) kuti mwenje uuye. Chiedza chinongodzima chete kana ma switch ese ari maviri akadzimwa, izvo zvinovhura dunhu zvachose.

Kune masitepisi, iwe unofanirwa kukwanisa kudzima mwenje neiyo yepamusoro kana yepasi switch, saka iwe unogona kuona kuti parallel kurongeka ndiyo yakanyanya kufanira.

dzidziso yemagetsi

Tinogona kutarisa zvakasiyana-siyana kuti tinzwisise mutsauko pakati pedunhu rakavharwa uye dunhu rakavhurika mune zvakadzama. Misiyano iyi inoratidzwa mutafura iri pasi apa.

Saiti yakavhurika iri muoff state nekuti dunhu rakavhurika kana kuti harina kukwana, nepo rakavharwa redunhu riri kunze kwenyika nekuti dunhu rinoenderera kana kuvharwa. Dunhu rakavhurika haribvumiri ikozvino kuyerera, uye hapana kufambiswa kwema electrons kana kutamiswa kwesimba remagetsi. Kusiyana neizvi, dunhu rakazaruka rinobvumira ikozvino kufamba. Naizvozvo, maerekitironi uye simba remagetsi zvinotamiswa zvakare.

Iyo voltage (kana inogona mutsauko) panguva yekuzorora mune yakavhurika dunhu ichave yakaenzana neyekugovera voltage uye inoonekwa isiri zero, asi mune yakavharwa dunhu ichave inenge zero.

Tinogonawo kuratidza mumwe musiyano mukuramba tichishandisa Ohm's Law (V = IR). Dunhu rakazaruka richave risingagumi nekuda kwe zero ikozvino (I = 0), asi muvharo yakavharwa ichaenderana nehuwandu hwezvino (R = V / I).

Aspect	Vhura dunhu	dunhu rakavharwa

Saka, dunhu rakakwana kana kushanda chete kana rakavharwa, kwete kuvhurika.

Pamusoro peiyo nzira yakakwana uye isina kukanganiswa yazvino, dunhu rakavharwa rinoda zvinotevera zvinhu:

• An active voltage source, sebhatiri.
• Nzira yacho inogadzirwa neconductor yakaita sewaya yemhangura.
• Mutoro uri mudunhu, senge girobhu.

Kana zvese izvi zvikaitika, maerekitironi anoyerera akasununguka mudunhu rese.

Tarisa zvimwe zvezvinyorwa zvedu pazasi.

• Maitiro ekuwedzera waya isina kwayakarerekera kune iripo mwenje switch
• Ungabatanidza sei chibatiso chemwenje
• Maitiro ekuyedza dunhu rinotyora ine multimeter
