Amagama asisiseko:
Isixhobo sokutshintsha kunye nesixhobo sokulawula ligama elisisiseko, elibandakanya i-switchgear kunye nokudibanisa kunye nolawulo oluncedisayo, ukufumanisa, ukukhuselwa kunye nokulungelelanisa izixhobo.Kukwabandakanya ukudibanisa izixhobo zombane kunye nezixhobo ezinocingo lwangaphakathi, izixhobo ezincedisayo, izindlu kunye neendawo ezixhasayo zesakhiwo.I-Switchgear isetyenziselwa ukuvelisa amandla, ukuhanjiswa, ukuhanjiswa kunye nemisebenzi yokuguqula amandla ombane.Isixhobo sokulawula sisetyenziselwa umsebenzi wokulawula isixhobo sokusetyenziswa kwamandla.
Isixhobo sokutshintsha kunye nesixhobo solawulo sibandakanya iikhonsepthi ezintathu ezisisiseko:
• ukubekwa wedwa
Ukhuseleko, cima unikezelo lombane okanye wahlule isixhobo okanye icandelo lebhasi kunikezelo lombane ngalinye ukwenza icandelo elizimeleyo lesixhobo (umzekelo, xa kuyimfuneko ukusebenza kwi-conductor ephilayo).Njengokutshintsha komthwalo, i-disconnector, i-breaker circuit kunye nomsebenzi wokuzihlukanisa, njl.
• ulawulo (kwi-off)
Ngenjongo yokusebenza kunye nokugcinwa, qhagamshela okanye unqamule phantsi kweemeko eziqhelekileyo zokusebenza.Njengomnxibelelanisi kunye ne-motor starter, ukutshintshela, ukutshintshela ngokukhawuleza, njl.
• ukhuseleko
Ukuthintela iimeko ezingaqhelekanga zeentambo, izixhobo kunye nabasebenzi, njengomthwalo ogqithisiweyo, isiphaluka esifutshane kunye ne-grounding fault, indlela yokuqhawula i-fault current isetyenziselwa ukuhlukanisa iphoso.Njenge: i-circuit breaker, tshintsha iqela le-fuse, i-relay yokukhusela kunye nokudibanisa izixhobo zokulawula, njl.
Switchgear
1. Fuse:
Isetyenziswa ikakhulu njengokhuseleko lwesekethe emfutshane.Xa isiphaluka sifutshane okanye sithwele kakhulu, siya kuxuba ngokuzenzekelayo kwaye sinqumle isiphaluka sokukhusela.Ikwahlulwe ngohlobo oluqhelekileyo kunye nohlobo olukhethekileyo lwe-semiconductor.
2. Iswitshi yokulayisha / iswitshi yefuse (tshintsha iqela le-fuse):
Izixhobo zokutshintsha oomatshini ezinokuqhagamshela, ukuthwala kunye nokuqhawula umsinga oqhelekileyo kunye nokuthwala okwangoku phantsi kweemeko ezingaqhelekanga (ezi zitshintshi azikwazi ukukhupha umsinga ongaqhelekanga wendlela emfutshane)
3. Isakhelo sesekethe yefreyimu (ACB):
Ireyithingi yangoku yi-6300A;Ixabiso lombane kwi-1000V;Ukuqhawula umthamo ukuya kwi-150ka;Ukukhutshwa kokhuseleko ngeteknoloji ye-microprocessor.
4. I-molded case circuit breaker (MCCB):
Ireyithingi yangoku yi-3200A;Ixabiso lombane kwi-690V;Ukuqhawula amandla ukuya kwi-200kA;Ukukhutshwa kokhuseleko kwamkela itekhnoloji ye-electromagnetic okanye i-microprocessor.
5. I-Miniature circuit breaker (MCB)
Ireyithingi yangoku ayikho ngaphezu kwe-125A;Ixabiso lombane kwi-690V;Ukophula amandla ukuya kuthi ga kwi-50kA
6. Ukukhutshwa kokhuselo lwe-electromagnetic kuyamkelwa
I-Residual current (evuzayo) i-circuit breaker (rccb/rcbo) I-RCBO ngokubanzi yenziwe yi-MCB kunye nezincedisi ezishiyekileyo.Kuphela i-breaker circuit encinci kunye nokhuseleko lwangoku olushiyekileyo kuthiwa yi-RCCB, kunye nesixhobo sokukhusela sangoku sibizwa ngokuba yi-RCD.
