Kunzwisisa Basa reKuchinja Mutoro muMasisitimu Emagetsi Emazuva Ano

Masisitimu emagetsi emazuva ano ave akaomarara zvakanyanya sezvo maindasitiri, zvivakwa zvemabhizinesi, uye zvivakwa zvinoda magetsi akasimba uye asingadzoreki. Kuti zvive nechokwadi chekuti mashandiro akachengeteka uye kugadziriswa kwakanaka, network dzemagetsi dzinoshandisa michina yakasiyana-siyana yekuchinja nekudzivirira. Pakati pezvikamu izvi, Chinja Chekutakurainoita basa rakakosha mukudzora nekuparadzanisa macircuit emagetsi pasi pemamiriro ezvinhu akajairwa ekutakura.

Kunyangwe isingape dziviriro ye "short-circuit" se "circuit breaker", inoshandiswa zvakanyanya mu "distribution systems" yekutonga mashandiro, kupatsanura kuchengetedza, uye kuvimbika kwe "system".Chinja Chekutakuramabasa ayo uye painoshandiswa zvinobatsira mainjiniya nevatariri vezvivakwa kugadzira masisitimu emagetsi akachengeteka uye anoshanda zviri nani.

1. Chii chinonzi Load Switch uye Inoshanda Sei MuMasisitimu Emagetsi?

Chinotsikisa mutoro mudziyo wemagetsi wakagadzirirwa kubatanidza kana kubvisa macircuit emagetsi zvakachengeteka pavanenge vachitakura load current yakajairwa. Kusiyana nema isolators, ayo anofanirwa kushanda chete kana circuit yapera simba, ma load switch anokwanisa kukanganisa current mumamiriro ezvinhu akajairwa ekushanda.

Chishandiso ichi chinowanzo kuve nezvinhu zvakakosha zvakati wandei:

• Sisitimu yekubataiyo inovhura kana kuvhara dunhu

• Maitiro ekushandisasenge mubato wemaoko kana actuator ine mota

• Chimiro chekudzima moto cheArckudzora nekudzvinyirira ma arc emagetsi panguva yekuchinja

Kana switch yacho ichishanda, matinji acho anoparadzana kana kubatana, zvichibvumira vashandisi kudzora kufamba kwemagetsi. Basa iri rinoita kutiChinja Chekutakurazvinonyanya kubatsira mumapaneru ekuparadzira, makabati ekudzora maindasitiri, uye masisitimu ekufambisa magetsi.

2. Musiyano Mukuru Pakati peLoad Switch, Circuit Breaker, uye Isolator

Masisitimu emagetsi anowanzo sanganisira michina yakasiyana-siyana yekuchinja, imwe neimwe yakagadzirirwa chinangwa chaicho. Kunzwisisa mutsauko uripo pakati pawo kwakakosha pakugadzira masisitimu nemazvo.

Kuchinja Kwemutoro vs Kuputsa Dunhu
Muchina wekupwanya dunhu wakagadzirwa kwete kungochinja macircuit chete asiwo kudzivirira kubva pakuwanda kwemagetsi uye mapfupi. Unogumburwa woga kana mamiriro ezvinhu asina kujairika akaitika. Kusiyana neizvi, chinja chekuisa mutoro hachipe mabasa ekudzivirira; chinongoshanda chete pakuchinja nekuparadzanisa magetsi.

Chinja Chekutakura vs Chinobvisa Mutoro
Chinobvisa magetsi (kana kuti disconnect switch) chinonyanya kushandiswa pakugadzirisa uye chinofanira kungoshandiswa chete kana circuit yatove isina simba. Hachikanganisi load current. Zvisinei, load switch inogona kutyora current zvakachengeteka mumamiriro ezvinhu akajairwa eload.

Mabasa Anobatsira muSistimu dzeMasimba
Munzvimbo dzakawanda dzinoiswa, zvishandiso izvi zvinoshanda pamwe chete. Macircuit breaker anobata dziviriro yezvikanganiso, ma load switch anopa kudzora mashandiro, uye ma isolators anopa kupatsanura kunooneka kwemabasa ekugadzirisa.

3. Mashandisirwo Akajairika muMagetsi eMaindasitiri neMabhizinesi

Maswichi ekutakura zvinhu anoshandiswa zvakanyanya munzvimbo dzakasiyana siyana uko kushandura zvinhu nenzira inodzorwa uye kupatsanurwa kwakachengeteka kunodiwa.

Zvivako zvemaindasitiri
Mafekitori ekugadzira anowanzo vimba nemaswichi ekutakura zvinhu mukati memabhodhi ekuparadzira zvinhu nenzvimbo dzekudzora mota kuti atarisire magetsi emidziyo uye agone kuchengetedza zvakachengeteka.

Zvivako zvemabhizinesi
Nzvimbo dzekutenga, mahofisi, uye mahotera anoshandisa ma "shopping panels" ekugovera magetsi mashoma kudzora ma "power circuits" akasiyana.

Masisitimu emagetsi ekuchengetedza
Mumasystem emagetsi ejenareta kana ekuchengetedza, maswichi emagetsi anogona kubatsira kupatsanura masosi emagetsi panguva yekugadzirisa kana kugadzirisa sisitimu.

Mapaneru emagetsi uye switchgear
Kazhinji zvinosanganiswa muma "switchgear assemblies" nema "distributing cabinet", zvichiita kuti maseketi emagetsi ashande zviri nyore uye zvakachengeteka.

Mashandisirwo aya anoratidza kuchinjika uye kuvimbika kweChinja Chekutakuramumagetsi emazuva ano.

4. Zvakanakira Kuchengetedzeka Pakuparadzanisa Nekuchengetedza Magetsi

Chimwe chezvakanakira zvikuru zvema "load switch" ndiko kuchengetedzeka kwazvinoita panguva yekugadzirisa magetsi uye mashandiro awo.

Kuchengetedzwa kwakavandudzwa kwekushanda
Vashandi vanogona kubvisa macircuit ane simba remagetsi rinorema pasina kuisa njodzi yekukuvadzwa kwakanyanya kana kukuvara kwemidziyo.

Njodzi dzekugadzirisa dzakaderera
Nekuparadzanisa zvikamu zvehurongwa hwekugovera, mainjiniya vanogona kuongorora kana kugadzirisa michina zvakachengeteka.

Kuvimbika kwesystem kwakawedzerwa
Maswichi ekutakura zvinhu anobvumira kuvharwa kwakarongwa uye kupatsanurwa kwesystem, zvichideredza kukanganiswa panguva yekugadzirisa.

Kutevedzera mitemo yekuchengetedza
Mitemo yakawanda yekuchengetedza magetsi inokurudzira michina yekushandura neyokuparadzanisa zvinhu kuti ideredze njodzi dzekushanda uye ive nechokwadi chekuti nzvimbo yebasa yakachengeteka.

Zvakanakira izvi zvinoita kuti maswichi emagetsi ave chinhu chakakosha mukugadzira masisitimu emagetsi akachengeteka.

5. Zvinhu Zvekufunga Nezvekusarudza Chinja Chekusimudza Mutoro

Kusarudza switch yekurekodha yakakodzera kunoda kuongorora zvinhu zvakasiyana-siyana zvehunyanzvi uye zvekushanda.

Rated current uye voltage
Switch inofanira kuenderana nehukuru hwemagetsi hwedunhu rayakaiswa.

Kugara kwenguva refu kwemagetsi nemechanical
Midziyo yepamusoro-soro yakagadzirirwa kushanda kwenguva refu uye kushandura-chinja kakawanda.

Rudzi rwekugadza
Sarudzo dzingasanganisira magadzirirwo akaiswa pamadziro, kuiswa kweDIN-rail, kana kubatanidzwa mumakabati eswitchgear.

Nzira yekushanda
Zvichienderana neapplication, maswichi anogona kushandiswa nemaoko kana kuti nemota kuti adzorerwe ari kure.

Kutevedzera mitemo yepasi rose
Mitemo yakaita seIEC neUL inoita kuti chigadzirwa chienderane nezvinodiwa zvekuchengetedza uye mashandiro azvo.

Kusarudza nokungwarira kunoita kuti zvinhu zvienderane nehurongwa hwemagetsi hwese uye kunovandudza kuvimbika kwenguva refu.

Mhedziso

Sezvo zvivakwa zvemagetsi zvichiramba zvichikura muhukuru uye kuoma, zvishandiso zvekushandura uye zvekuparadzanisa zvinogara zvichikosha pakuchengetedza kuchengetedzeka uye kushanda zvakanaka. Maswichi ekutakura zvinhu anopa mhinduro inoshanda yekudzora macircuit emagetsi uye michina yekuparadzanisa panguva yekugadzirisa pasina kukanganisa kugadzikana kwehurongwa hwese.

Nekunzwisisa misimboti yavo yekushanda, kusiyana kwezvimwe zvishandiso zvekuchinja, uye nzira dzakakodzera dzekusarudza, mainjiniya nevatariri vezvivakwa vanogona kubatanidza maswichi emagetsi zvinobudirira munetwork dzemazuva ano dzekuparadzira magetsi.

Mibvunzo Inowanzo bvunzwa

1. Chii chinonyanya kukosha pakuchinja load switch?
Chishandiso chekuisa mutoro chinonyanya kushandiswa kubatanidza kana kubvisa macircuit emagetsi ane simba remagetsi rinouya panguva imwe chete ukuwo chichipa simba rekuchengetedza mashandiro.

2. Ko chinja chekuisa mutoro chinogona kudzivirira kubva kuma "short circuits" here?
Kwete. Maswichi ekutakura zvinhu haape mabasa ekudzivirira. Macircuit breaker kana ma protective relay anodiwa kuti pave ne overload uye short-circuit protection.

3. Maswichi ekutakura zvinhu anowanzoiswa kupi?
Dzinowanzoiswa mumapaneru ekuparadzira, maswitchgear emaindasitiri, nzvimbo dzekudzora mota, uye masisitimu emagetsi ekuchengetedza.

4. Sei maswichi ekutakura zvinhu akakosha pakugadzirisa?
Zvinobvumira vashandi kuti vaparadzanise macircuit emagetsi zvakachengeteka, zvichiita kuti basa rekuongorora nekugadzirisa rive rakachengeteka uye rinoshanda zvakanaka.
