How to Select and Install Control Protection Switch Correctly for Different Scenarios

Nhanganyaya

Mumasisitimu ekugovera magetsi ane simba shoma, kufananidza zvikamu zvekuchengetedza zvakakodzera ndiyo nhanho yekutanga yekudzivirira kutadza kwemagetsi netsaona dzekuchengetedza.Chinja Chekudzivirira Kudzora, inozivikanwa seCPS muindasitiri, chishandiso chemagetsi chinoshanda mabasa akawanda chinosanganisa kudzora, kudzivirira overload uye kuona zvikanganiso muyuniti imwe chete. Kusiyana nemagadzirirwo echinyakare anoshandisa macontactor akasiyana uye macircuit breakers, CPS inoita kuti waya dzive nyore uye inoderedza nzvimbo dzekukundikana mumagetsi ekugovera marobhoti. Kusarudza modhi isingaenderane kana kucheka makona panguva yekuisa kunowanzo tungamira mukugumburwa kazhinji, kukuvara kwemidziyo uye kunyange njodzi dzekuvhunduka kwemagetsi, saka kusarudzwa kwakajairwa uye kuiswa hazvigoneke kune ese mashandisirwo. Chinyorwa chino chinotsanangura nzira dzinoshanda, dzakasimbiswa dzekusarudza nekuisa CPS, tichitarisa kune zvinodiwa zveindasitiri kuti ive nechokwadi chekuti inoshanda uye inotevedzera mitemo.

1. Nheyo dzeKusarudza Zvinhu Zvikuru pazvinodiwa zveMutoro weMagetsi

Mutemo wekutanga wekushandisa CPS nemazvo ndewekuenzanisaChinja Chekudzivirira Kudzorazvichienderana nerudzi rwemutoro chaiwo nenzvimbo yekushanda. Kune zvinhu zvinodzivirira zvakaita semwenje yemukati uye maheater emagetsi, mamodheru eCPS akajairwa ane mabasa ekudzivirira ekutanga akakwana; kune zvinhu zvinodzivirira zvakaita semamota emufekitori, maelevator nemapombi emvura, sarudza mamodheru ane simba rekudzivirira kukwira kwemagetsi uye kushivirira kwemhepo pfupi kuti abate magetsi akakwira pakutanga. Maparamita akakosha anofanirwa kuongororwa nokungwarira: magetsi akayerwa, voltage yekushanda, kugona kutyoka uye IP protection level zvese zvinofanirwa kukodzera gadziriro chaiyo yekugovera magetsi.

Pamitoro yakakosha yakaita semichina inotsigira hupenyu hwemuchipatara uye magetsi emukamuri redata, sarudza mamodheru eCPS akavimbika uye akasimba zviri nani. Zvigadzirwa zvese zvinokwanisa zvinofanirwa kusangana neIEC 60947-6-2 uye GB 14048.9 mwero wemagetsi wakaderera, izvo zvinosungirwa kuve nechokwadi chekuti chigadzirwa chakanaka uye kuchengetedzeka panzvimbo yacho (Low-Voltage Electrical Appliances Standardization Committee, 2024).

2. Maitiro Ekuisa Akajairika uye Mitemo Yekuchengetedza

Usati waisa, ita basa rekutanga rekugadzirira: tarisa CPS kuti haina kukuvara here kana kuti hapana ma terminals akasununguka kana kuti zvikamu zvisipo, gadzirira maturusi emagetsi ehunyanzvi, uye bvisa simba rese rinoenda kucircuit kudzivirira kuvhunduka kwemagetsi. Gadzirisa mudziyo paplate yakasimba, yakati sandara, chengetedza kure nemasimba akasimba ekuzunguzika, uye sunga waya zvichienderana nema terminal labels uye phase sequence - reverse wiring uye loose connections hazvibvumidzwe zvachose.

Vhara majoini ese emagetsi zvachose, uye bvisa njodzi dze "short-circuit" usati wadzorera magetsi. Nzvimbo yekuisa inofanira kunge yakaoma uye isina guruva, ine tembiricha iri pakati pe -5℃ ne40℃. CPS yakajairwa haigone kushandiswa munzvimbo dzine hunyoro, dzinoparadza kana dzinoputika; mhando dzakasarudzika dzinodzivirira kuputika kana dzinodzivirira hunyoro dzinofanira kushandiswa munzvimbo idzi dzakaoma (National Electrical Engineering Installation Code, 2023).

3. Nzira dzeKufananidza Dzinoenderana Nemamiriro Ezvinhu

Mamiriro akasiyana-siyana anoda kugadziriswa kweCPS kwakanangana. Maworkshop emaindasitiri nemitsetse yekugadzira inoda CPS inorema ine simba rekupaza, yakakodzera kutanga mota nguva nenguva uye kushanda kwenguva refu. Zvivako zvemabhizinesi zvakaita sezvivako zvemahofisi nezvitoro zvinogona kushandisa mamodheru eCPS madiki, ayo anochengetedza nzvimbo uye anogutsa zvinodiwa zvekuchengetedza maelevator, mwenje wekukurumidzira uye air conditioning yepakati. Kushandiswa kumba, mamodheru madiki uye ari nyore eCPS ari nani, achitarisa pakubuda kwemvura uye kudzivirirwa kwehuwandu hwemagetsi kuti ave nechokwadi chekuti magetsi akachengeteka zuva nezuva.

Nzvimbo dzakaoma dzakadai semafekitori emakemikari, magaraji epasi pevhu nemigodhi zvinoda CPS yakavharwa, inodzivirira hunyoro uye inodzivirira kuputika kuti ikwanise kushanda zvakanaka.

4. Kuedzwa Mushure meKuiswa uye Kugadziriswa kwezuva nezuva

Mushure mekuisa, tanga waita bvunzo yekusava nekutakura zvinhu kuti utarise mashandiro eswitch uye mwenje wechiratidzo, wobva waita bvunzo yekutakura zvinhu pasi pesimba rakatarwa kuti usimbise mashandiro akasimba. Kugadzirisa kwezuva nezuva kuri nyore: tarisa waya dzisina kusimba, kupisa zvakanyanya uye ruzha rusina kujairika mwedzi mitatu yega yega, uye ita bvunzo yakazara yekushanda kamwe chete pagore. Chengeta zvinyorwa zvekugadzirisa kuti utarise mamiriro emuchina uye kugadzirisa matambudziko akavanzwa nenguva.

5. Zvikanganiso Zvakajairika Zvekuisa uye Kugadzirisa Matambudziko

Kukundikana kukuru kweCPS kunokonzerwa nekuiswa zvisina kunaka: waya dzemagetsi dzinodzokera shure, marongero asina kunaka eparameter uye nzvimbo isina kunaka yekuisa ndiwo matambudziko anowanzoitika, zvichikonzera kutadza kweswitch kana kudonha kwenhema nguva nenguva. Kukanganisa kwakajairika kunosanganisira kuita kusingapinduri, kudonha kwekudzivirira nguva nenguva uye ruzha rusina kujairika. Pakugadzirisa matambudziko, tarisa waya kutanga, wobva waongorora maparameter, uye ongorora zvikamu zvemukati kana zvichidikanwa; kugadzirisa kwese kunofanirwa kuitwa nevashandi vemagetsi vane hunyanzvi. Kukundikana kwakawanda kunogona kudzivirirwa nekutevera mitemo yekuisa zvakanyatsonaka.

Mhedziso

Kusarudzwa uye kuiswa kwakakodzera kweChinja Chekudzivirira KudzoraNdiwo hwaro hwekushanda kwakachengeteka uye kwakagadzikana kwemasisitimu ekugovera magetsi ane voltage shoma, zvichida kutariswa kwakazara kwehunhu hwemutoro, mamiriro ekushandiswa uye kutevedzera mitemo yakajairwa. Kutevera matanho akajairwa ekusarudza, kuisa nekugadzirisa kunogona kuwedzera hupenyu hwemichina, kuderedza kutadza kushanda uye kubvisa njodzi dzemagetsi. Kune ese ari maviri mamiriro emagetsi emumaindasitiri neevanhu, aya nhungamiro dzinoshanda dzakakosha pakushanda kwemagetsi kwakachengeteka uye kwakanaka.

Mibvunzo Inowanzo bvunzwa

Mubvunzo: Ko CPS yakajairika inogona kuiswa mupasi pevhu kana muimba yekugezera ine hunyoro here?A: Kwete, CPS yakajairwa haina hunyoro kana kuti haipindi mvura. Shandisa CPS yakakosha inodzivirira hunyoro kana kuputika panzvimbo dzine hunyoro, ngura uye dzine hunyoro hwakawanda.
Q: Ungaziva sei kuti CPS ine ratio yemagetsi?A: Pamitoro yakajairika, sarudzai current yakayerwa ka1.1-1.2 kupfuura current yekushanda yakayerwa nemutoro; wedzerai 20%-30% yemamota uye loads inductive kuti ikwanise kutakura masurges ekutanga.
Mubvunzo: Ndingaisa CPS ndisina chitupa chemagetsi here?A: Kwete, kuiswa kweCPS kunosanganisira waya dzehunyanzvi uye kushanda kwadzo live, kunofanirwa kuzadzikiswa nevashandi vemagetsi vane hunyanzvi kudzivirira tsaona dzekuchengetedza.
Mubvunzo: CPS inofanira kuongororwa kangani?A: Kuongorora nemaziso nguva dzose mwedzi mitatu yega yega, bvunzo yakazara yekushanda uye mashandiro kamwe chete pagore kuti uve nechokwadi chekuti mashandiro akasimba.
