I-circuit breaker ibhekisa kwisixhobo sokutshintsha esinokucima, sithwale kwaye sicime umsinga phantsi kweemeko eziqhelekileyo zeluphu kwaye sinokucima, sithwale kwaye sicime umsinga phantsi kweemeko ezingaqhelekanga zeluphu ngaphakathi kwexesha elithile.Iziphuli zesekethezahlulwe zaba zii-circuit breakers ezine-voltage ephezulu kunye nee-circuit breakers ezine-voltage ephantsi ngokwendlela ezisetyenziswa ngayo, kwaye ulwahlulo lwemigca ene-voltage ephezulu kunye neye-voltage ephantsi luyi-fuzzy, ngokubanzi lubizwa ngokuba zizixhobo ze-voltage ephezulu ngaphezu kwe-3kV. Ukongeza, ulwahlulo lwee-circuit breakers lunokwahlulwa ngokwenani lee-pole: i-single-pole, i-two-pole, i-three-pole kunye ne-four-pole; Ngokwendlela yokufaka: kukho uhlobo lwe-plug-in, oluzinzileyo kunye nolwe-drawer.Isitshixo sokhuseleko se-circuit breakerIsetyenziselwa isixhobo sokwahlukanisa amandla ombane, oko kukuthi, i-lock tag yokuthintela ukusetyenziswa kakubi ngexesha lokugcinwa kwesixhobo esichasene neengozi. Umgaqo woyilo lwazo zonkeukuvalelwa ngaphandle kwesekethekukutshixa iswitshi ye-circuit breaker emva kokuba umbane ungasebenzi ukuthintela nabani na ngaphandle komntu onoxanduva ukuvula i-circuit breaker. Ke ngoko, xa sikhetha i-circuit breaker efanelekileyoisitshixo se-circuit breaker, ikakhulu kukukhetha isixhobo esifanelekileyo sokuthintela iingozi xa utshintsha i-circuit breaker.
Iingozi zombane zinokubangela ukwenzakala komntu okanye ukufa. Ke ngoko, isitshixo se-circuit breaker senzelwe ukwahlukanisa umbane ngokwasemzimbeni kwaye sikhusele ukhuseleko lokusingqongileyo lwabasebenzi kangangoko kunokwenzeka.
Ukusebenzisaukutshixelwa ngaphandle kwe-circuit breakerIbonelela ngeenzuzo ezibalulekileyo ezininzi, ingakumbi ekuphuculeni ukhuseleko kunye nokuthintela iingozi kwiinkqubo zombane.Nazi izibonelelo eziphambili:
1. Ukhuseleko oluphuculweyo
Ithintela ukwenziwa kwamandla ngengozi kweesekethe ngexesha lokugcinwa okanye ukulungiswa, ikhusela abasebenzi ekutshayweni ngumbane, ukutsha, okanye ukutshaywa ngumbane.
Iqinisekisa ukuba iisekethe zihlala zingasebenzi kakuhle de umsebenzi ugqitywe, nto leyo enciphisa umngcipheko wokwenzakala.
2. Ukuthobela iMimiselo yoKhuseleko
Inceda imibutho ukuba ithobele i-OSHA (Occupational Safety and Health Administration) kunye neminye imigangatho yokhuseleko, eyalela ukusetyenziswaukutshixa/ukuthega (iLOTO)iinkqubo zeenkqubo zombane.
Inciphisa umngcipheko wezohlwayo okanye isohlwayo sokungathobeli imithetho.
3. Ithintela Ukufikelela Okungagunyaziswanga
Itshixa i-circuit breaker kwindawo ethi “cima”, ithintela abasebenzi abangagunyaziswanga ukuba bayivule ngengozi okanye ngabom.
Inika umqobo obonakalayo ekuphazamiseni.
4. Unxibelelwano Olucacileyo
Idla ngokuquka iithegi okanye iilebhile ukubonisa ukuba kutheni isekethe ivaliwe, ngubani oyigunyazisileyo, kwaye nini na ukuba iza kubuyiselwa.
Iphucula unxibelelwano phakathi kwabasebenzi kwaye inciphisa ukudideka.
5. Ikhusela Izixhobo
Ithintela ukunyuka kwamandla ngengozi okanye umbane ongalindelekanga, okunokonakalisa izixhobo okanye oomatshini.
Iqinisekisa ukuba izixhobo zivaliwe ngokukhuselekileyo kwaye zahlulwe ngaphambi kokuba zilungiswe.
6. Yehlisa uxanduva
Ubonisa ukuzibophelela kukhuseleko kwindawo yokusebenza, nto leyo enokunciphisa uxanduva xa kuthe kwenzeka iingozi.
Inika ubungqina obubhaliweyo bokuba kulandelwe iinkqubo zokhuseleko ezifanelekileyo.
7. Ukuguquguquka kwezinto
Ingasetyenziswa kwiindidi ezahlukeneyo zee-circuit breakers, nto leyo eyenza ukuba ibe sisixhobo esisebenziseka lula kwiinkqubo ezahlukeneyo zombane.
8. Ixabiso Eliphantsi
Ithintela ixesha lokungasebenzi elibizayo, umonakalo wezixhobo, okanye ukwenzakala emsebenzini ngokuqinisekisa iindlela zokusebenza ezikhuselekileyo.
9. Ixhasa iinkqubo ze-Lockout/Tagout (LOTO)
Idibeneyo kwiinkqubo zeLOTO, ukuqinisekisa ukuba imithombo yamandla yahlulwe kwaye ilawulwa ngokufanelekileyo.
