UMAHLUKO PHAKATHI KWESWISHI YOKUKWEHLISA KUNYE NETSHINTSHO YOMLAWULO

Abantu abaninzi abayiqondi iswitshi yokwahlula kunye nomthwalo wokutshintsha, iintlobo ezimbini zokutshintsha zithathwa njengehlabathi liphela, zinokutshintshwa, kodwa ezinye izihlandlo azikwazi ukutshintshwa, i-Kesu electromechanical xiaobian ikuxelela ukuba yintoni umahluko phakathi kokutshintsha kokwahlula kunye nokutshintsha umthwalo.

Umtshini wokuzihlukanisa ngokwawo awunaso isixhobo sokucima i-arc, unokuqhawula kuphela i-current rated current, ngoko kwi-loop kuphela njengento yodwa, edinga ukugcinwa iya kuhlukaniswa nombane kunye nomthwalo.

Ukutshintshwa komthwalo kunesixhobo sokucima i-arc ukukhupha i-fault current, kwaye uqhagamshelwano lwayo lunokusetyenziswa njengento yokutshintsha yedwa, kunye nokuqhawula kunye nokuqhawula imisebenzi emibini.
Ukutshintsha komthwalo ngokubanzi kuqulunqwe ngeefuse kunye nokuqhawula ukudibanisa. Umtshini wokuqhawula usetyenziselwa umsebenzi oqhelekileyo we-loop, kwaye i-fuse isetyenziselwa ukukhupha i-fault current ye-loop.

Intshayelelo yokucima unxibelelwano:

Ukwahlula iswitshi luhlobo lwesixhobo sokutshintsha esisetyenziswa ikakhulu ukwahlula unikezelo lwamandla, ukusebenza kokutshintsha, ukudibanisa kunye nokusika isekethe encinci yangoku, ngaphandle kwe-arc yokucima umsebenzi.
Xa umtshini wokuzihlukanisa ukwindawo eyahlukileyo, kukho umgama wokugquma phakathi kwabafowunelwa ngokuhambelana neemfuno kunye nophawu olucacileyo lokuqhawula;
Isitshixo esikwaziyo, sikwindawo evaliweyo, ukuthwala umsinga phantsi kweemeko eziqhelekileyo ze-loop kwaye sisebenza phantsi kweemeko ezingaqhelekanga (umz. isekethe emfutshane) kangangexesha elithile.
Ngokuqhelekileyo isetyenziswa njengeswitsha yokwahlula ombane aphezulu, oko kukuthi, umbane olinganiselweyo ngaphezulu kwe-1kV iswitsha yodwa, umgaqo wayo wokusebenza kunye nolwakhiwo lulula, kodwa ngenxa yokusetyenziswa kweemfuno ezinkulu, ezinokuthembeka okuphezulu, isitishi, uyilo lweplanti yamandla, ukusekwa kunye nokusebenza ngokukhuselekileyo kwempembelelo enkulu.
Into ephambili yokutshintsha ukuqhawula kukuba ayinayo i-arcing ikhono kwaye inokuvula kunye nokuvala isiphaluka ngaphandle komthwalo wangoku.
Inqaku lizisa umsebenzi, iimpawu, iintlobo, izicelo, ukuphuculwa kokuthintela impazamo, ukugcinwa, iingxaki eziqhelekileyo zokutshintshwa kwe-isolation.

Intshayelelo emfutshane yokutshintsha umthwalo:

Ukutshintsha komthwalo sisixhobo sokutshintsha phakathi kwe-breaker circuit kunye ne-switch yokuqhawula. Inesixhobo esilula sokucima i-arc, esinokunqumla umthwalo olinganisiweyo wangoku kunye nomthwalo othile wangoku, kodwa awukwazi ukunqumla isiphaluka esifutshane.
Ukuhlelwa kokutshintsha komthwalo: ngokusetyenziswa kwamandla ombane kunokwahlulwa kuluhlu oluphezulu lomthwalo wombane kunye nokutshintsha komthamo ophantsi.
Ukutshintsha komthwalo kusetyenziselwa ukuvula kunye nokucima umbane wangoku, okanye zingasetyenziswa kunye ne-high-voltage fuses endaweni ye-breakers circuit.
Ngenxa yokusebenziseka kwayo kunye nexabiso elifanelekileyo, ukutshintshwa komthwalo kusetyenziswa ngokubanzi kwinkqubo yokuhambisa i-10kV.
Ukhetho olufanelekileyo lokutshintsha komthwalo kuyilo lubaluleke kakhulu ukuqinisekisa ukhuseleko kunye nokusebenza okuthembekileyo kwegridi yamandla.
