Ndezvipi zvinhu zvakakosha pakusarudza switch yekuchinja otomatiki?

1. Kuongororwa kwehunhu hwemutoro uye kugona kuenderana

1.1 Kuzivikanwa kwerudzi rwemutoro

Ongororo yakadzama yerudzi rwemutoro (resistive, inductive, capacitive, kana mixed) inoitwa. Mhando dzakasiyana dzemutoro dzine mhedzisiro yakakura pakukura kwemagetsi, hunhu hwekutanga hweATS. Semuenzaniso, mitoro yeinductive yakadai sekutanga kwemota inogadzira simba rekutanga rakawanda, zvichida kuti ATS ive nekukwanisa kuremedza zvakanyanya uye kushivirira kuvhunduka; mitoro yeinductive inogona kuburitsa simba rakawandisa panguva yekuchinja, zvichiita kuti ATS ive nenzira dzekudzivirira dzakakodzera.

1.2 Kurongwa kwekukosha kwemutoro

Kukosha kwemutoro kwakakamurwa muzvikamu zvekutanga (senge midziyo yeICU muzvipatara, maseva makuru munzvimbo dzedata), zvechipiri (senge midziyo yehofisi yakajairika, mwenje muzvivakwa zvemabhizinesi), uye zvechitatu (senge maair conditioner nemidziyo isiri yakakosha). Matanho akasiyana ekukosha ane zvinodiwa zvakasiyana zveATS maererano nenguva yekuchinja uye kuvimbika. Mitoro yekutanga inofanirwa kutariswa kuti magetsi arambe achienderera mberi.

2. Nguva yekuchinja uye zvinodiwa zvekuchinja mashandiro

2.1 Kuongorora nguva yekudzima simba inobvumidzwa

Nguva yepamusoro inobvumirwa yekudzima simba remagetsi inosarudzwa zvichienderana nehunhu hwayo. Semuenzaniso, michina yekombuta inowanzo bvumidza nguva pfupi yekudzima simba, kazhinji iri muchikamu che millisecond; nepo mimwe michina yemwenje yakajairika ichibvumira nguva yakareba yekudzima simba remagetsi.

2.2 Mhando dzemaitiro ekuchinjana akajairika uye hunhu

Nzira dzakajairika dzekuchinjana dzeATS dzinounzwa, dzakadai sePC level (switch yekuchinjana yemhando yese) uye CB level (circuit breaker type transfer switch). PC level ATS ine hunhu hwechimiro chiri nyore, kumhanya kwekuchinjana nekukurumidza, uye kuvimbika kwakanyanya, uye yakakodzera mamiriro ezvinhu ane zvinodiwa zvakanyanya zvenguva yekuchinjana; CB level ATS ine mabasa ekudzivirira overload uye short-circuit, asi nguva yayo yekushandura yakareba, yakakodzera mamiriro ezvinhu ane zvinodiwa zvekudzivirira zvakanyanya.

2.3 Sarudzo yekuchinja nguva

Maparamita akakosha eATS, akadai senguva yese yekuchinja (kusanganisira nguva yekuvhura nekuvhara) uye nguva yekuchinja inotangira, anotsanangurwa zvakajeka uye anovimbiswa kuti anosangana nezvinodiwa nemutoro. Panguva imwe chete, kuwiriraniswa pakati pesimba remagetsi akasiyana kunofungwa. Kune simba remagetsi risingachinji, ATS ine basa rekuchinja risingachinji inofanira kusarudzwa.

3. Zviratidzo zvekuvimbika uye zvinodiwa pakugadzirisa

3.1 Nguva Pakati Pekukundikana (MTBF)

MTBF chiratidzo chakakosha chekuyera kuvimbika kweATS. Kusarudza zvigadzirwa zveATS zvine kukosha kwakakwirira kweMTBF kunogona kuderedza mukana wekukundikana. Kunzwisisa data reMTBF rinopihwa nevagadziri uye kuita ongororo zvichibva pamashandisirwo chaiwo.

3.2 Hupenyu hwemakanika uye hupenyu hwemagetsi

Nyatsoteerera hupenyu hwemuchina (nguva dzekushanda) uye hupenyu hwemagetsi (nguva dzekushanda kwemutoro) hweATS. Hupenyu hwemuchina uye hupenyu hwemagetsi hwakareba, hupenyu hwebasa hweATS hwakareba, uye huwandu hwekuchengetedza nekutsiva hunoderedza. Sarudza ATS ine hupenyu hwakakwana hunotarisirwa zvichienderana nehuwandu hwekushandiswa hunotarisirwa nemakore.
