- Vuto Lapadera: Kuzindikira Moto Popanda Kuuyambitsa
Makina ochenjeza moto amakumana ndi vuto lalikulu m'malo oopsa. Ayenera kuzindikira moto moyenera—koma sayenera kupanga gwero la kuyatsa moto lomwe limayambitsa moto poyamba.
M'mafakitale opanga mankhwala, mafakitale oyeretsera mafuta, malo osungiramo mafuta, mafakitale opangira gasi, ndi malo opopera utoto, mlengalenga muli mpweya woyaka, nthunzi, kapena fumbi loyaka. Chingwe chodziwitsira moto chodziwika bwino, ngati chawonongeka kapena chafupika, chingapangitse kuti pakhale moto womwe ungayatse mlengalenga woopsa wozungulira.
Chingwe choteteza moto (IS) chimathetsa vutoli mwa kuphatikiza zinthu ziwiri zofunika:
| Mbali | Cholinga | Phindu |
| Kuchepetsa Mphamvu (Chitetezo Chamkati) | Zimaletsa mphamvu zamagetsi mu chingwe kotero kuti sizingayambitse kuyaka | Zotetezeka kuyika ndikugwiritsa ntchito m'malo oopsa a Zone 0/1/2 |
| Kukhulupirika kwa Dera (Kupulumuka pa Moto) | Imasunga ntchito ya dera nthawi yamoto weniweni | Ma alamu amatumizidwa ngakhale makina ena atalephera — chitetezo cha moyo |
Pa Dingzun Cable,Zingwe zathu zodziwira moto zomwe zili zotetezeka kwambiri zimapangidwa kuti zitetezeke m'malo oopsa komanso kuti zitetezeke pamoto, ndipo zatsimikiziridwa kuti zikugwirizana ndi miyezo yapadziko lonse lapansi yogwiritsira ntchito petrochemical, mankhwala, ndi mafakitale.
- Momwe Imagwirira Ntchito: Kuchepetsa Mphamvu + Kukhulupirika kwa Dera
Dongosolo lodzitetezera lozimitsa moto lili ndi zinthu zitatu zomwe zimagwira ntchito limodzi.

Mfundo Yoletsa Mphamvu:
Ngakhale ndi chotchinga chabwino kwambiri choletsa mphamvu kufika pa mphamvu (Cc)ndiinductance (Lc)Chingwe chodziwikiratu cha IS chochenjeza moto chili ndi Cc ndi Lc zochepa zomwe zalembedwa kuti zitsimikizire kuti ngakhale pakakhala vuto, mphamvu yosungidwayo singayambitse kuyaka.
Mfundo Yofunika Kwambiri Yokhudza Umphumphu wa Dera:
Pakabuka moto weniweni, zingwe zodziwika bwino zimasungunuka, zimatsekedwa, kapena zimatsegulidwa mkati mwa mphindi zochepa. Chingwe chochenjeza moto chokhala ndiumphumphu wa dera (CI)Kuyesa kumapitiliza kugwira ntchito kwa nthawi inayake (mphindi 30 mpaka 180+) — kuonetsetsa kuti ma alamu afika pagawo lowongolera ngakhale moto ukufalikira.
Pa Dingzun Cable,Zingwe zathu zochenjeza moto za IS zimapangidwa ndi zinthu zotsika za Cc/Lc (zoteteza malo oopsa) komanso zinthu zotentha kwambiri (zoteteza moto).
- Ma Ratings a Circuit Integrity: FE180, E30, ndi Kupitirira apo
Ziwerengero za umphumphu wa dera zimasonyeza nthawi yomwe chingwe chidzagwira ntchito panthawi ya moto.
Gome 2: Kuwerengera Kukhulupirika kwa Alamu ya Moto pa Chingwe cha Chingwe

| Chingwe cha LHD | Ma conductor awiri opotoka olekanitsidwa ndi polima yomwe imakhudzidwa ndi kutentha. Kutentha kukafika pachimake, polima imasungunuka, ma conductor amakhudzana, ndipo ma alarm amayamba kuyambitsa |
| Cholepheretsa cha IS | Kuchepetsa mphamvu kufika pamlingo wotetezeka |
| Gawo lowongolera | Imawunikira kukana kwa dera; imayambitsa alamu pa dera lalifupi |
Chifukwa Chake LHD Ndi Yoyenera Kumalo Oopsa:
- Ntchito yopanda pake— Palibe zamagetsi zomwe zimagwira ntchito m'dera loopsa
- Mphamvu zochepa— Mukalumikizidwa kudzera mu chotchinga cha IS, dera silingathe kupanga spark yotha kuyatsa
- Yotetezeka— Maselo otseguka kapena maselo afupi onse amapanga alamu (yoyang'aniridwa)
