Ukukhiya/ukuthega (i-LOTO): Faka amaketanga emishinini ngaphambi kokulungisa

Ukukhiya/ukuthega (i-LOTO): Faka amaketanga emishinini ngaphambi kokulungisa
Ukunyakaza okujwayelekile:
Ngemva kokunqamula ugesi, vala iswishi ngokukhiya okukhethekile
2. Lengisa uphawu oluyisixwayiso oluthi “Umsebenzi uyaqhubeka, ungawuvali umshini” (uphawu kumele lususwe ngumuntu ngokwakhe).
3. Hlola i-voltage ukuqinisekisa ukuthi ayikho i-voltage ngaphambi kokuthatha isinyathelo
Icala lengozi:
Uchwepheshe kagesi efektri ethile wehlulekileUkukhiya/ukuthegaukulungisa injini, futhi umqhubi wavala ngephutha iswishi, okwaholela ekuqhekekeni kwesandla sikagesi ngenxa yokuchotshozwa. (Ngemva kokulungiswa, kuyimpoqo ukuba "nomuntu oyedwa, ilokhi eyodwa, ipuleti elilodwa".)
Ii. Ukuhlolwa Kwe-Voltage Ephakeme: Ukuqinisekisa Ukuthi Kukhona Ugesi Empilweni Yomuntu Noma Cha
Ukunyakaza okujwayelekile:
1. Okokuqala, hlola izinto zikagesi ezisetshenziswayo ukuze uqinisekise ukuthi zisebenza kahle (qiniseka ukuthi aziphukile!)
Uma uhlola ugesi, gqoka amagilavu ​​​​okuvikela bese ubamba ingxenye engaphansi kwendandatho yokuvikela
3. Kumelwe kube khona abantu ababili ukuze kuhlolwe i-voltage enamandla aphezulu (oyedwa uyasebenza kanti omunye uqaphile). Ukusebenza okungalungile:
Insizwa entsha yazama ukuhlola ugesi ngesandla esisodwa kodwa yehluleka ukubona ukuthi umshini wokuthola ugesi awuthintani kahle. Yahlulela ngephutha ukuthi akukho ugesi, okwaholela ekushisweni kwe-arc kagesi. (Khumbula: Ukuhlolwa kukagesi okungalungile kulethe imigqa emibili yezinyembezi kubathandekayo bakho!)
Iii. Ukuhlolwa Kokushiswa Komoya: Nikeza isekhethi "ukuhlolwa ngokomzimba" ukuvimbela ukuvuza
Ukunyakaza okujwayelekile:
Kala ukumelana kokushisa kwesekethe nge-megohmmeter engu-500V (uma ingaphansi kuka-0.5MΩ, kufanele kulungiswe).
2. Ukugoqa imoto kubhekwa njengokufanelekile kuphela uma ukufakelwa phakathi kwezigaba kungaphezu kuka-2MΩ
3. Endaweni enomswakama, kala kanye ngesonto; endaweni eyomile, kala kanye ngenyanga
Ukulungiswa kwefektri:
Imishini eshabhu elithile yayivame ukukhubeka. Ngemva kokuhlolwa kokushisa, kwatholakala ukuthi izintambo zazigugile futhi zonakele. Ngemva kokushintshwa, izinga lokukhubeka lehle laya ku-zero (konga ama-yuan ayi-100,000 ezindlekweni zokulungisa i-short-circuit!)
