Le iswitshi yangaphandle yomthwalo wombane ophezulu yenzelwe ukutshintshela okuthembekileyo kunye nokhuseleko kuthungelwano losasazo lwe-voltage eliphakathi. Eyilwe ngesakhiwo sokucima i-arc i-vacuum edibeneyo kunye nenkqubo yokuhlukanisa i-mechanical, iqinisekisa ukusebenza kokuphazamiseka okuzinzile phantsi komthwalo kunye neemeko eziphosakeleyo. Isetyenziswa ngokubanzi kwiinkqubo zokuhambisa amandla kwizinto ezisetyenziswayo, izityalo zoshishino, izibonelelo zemigodi, kunye neziseko zemichiza, apho ukhuseleko lokusebenza kunye nokuqhubeka kubaluleke kakhulu.
Imveliso ithatha uyilo lwemodyuli yesakhiwo esenza lula ufakelo kwipali-enyuswe okanye ulungelelwaniso lwesikhululo. Inkqubo yayo yokugquma etywiniweyo iphucula ukuguquguquka kokusingqongileyo, ivumela ukusebenza okuzinzileyo phantsi kokufuma, uthuli, kunye nokuguquguquka kobushushu. Kwizicelo zobunjineli ezisebenzayo, i-Outdoor High Voltage Load Switch ihlala isetyenziswa njengesixhobo esingundoqo sokutshintsha kwiiyunithi eziphambili zeringi kunye neenkqubo ezizenzekelayo zokuhambisa.

Kwiinkqubo ezizisebenzelayo zokusasaza, i-Outdoor High Voltage Load Switch idla ngokufakelwa kwimigca exhonywe kwipali okanye kwizitishi ezidityanisiweyo ukuze kuvuleleke ukutshintshwa kwecandelo kunye nokwahlulwa kweempazamo. Ixhasa ukusebenza ngesandla kunye nemoto, iyenza ilungele zombini iigridi zemveli kunye nokuphuculwa kwegridi ehlakaniphile.
Ukususela kumbono wokulondoloza, yenzelwe kunye nesakhiwo esitywiniweyo kunye noqhagamshelwano olungagungqiyo, ukunciphisa imfuno yokukhonza rhoqo kunye nokuphucula iindleko zeendleko zobomi ekusebenzeni kwexesha elide.
I-Q1: Iphi i-Outdoor High Voltage Load Switch esetyenziswa ngokuqhelekileyo?
A: Isetyenziswa kakhulu kwiinkqubo zokusasaza i-10kV–12kV, kubandakanywa imizi-mveliso, iziza zemigodi, izitishi, kunye nophuculo lwegridi yamandla yasemaphandleni yokutshintsha umthwalo kunye nokwahlulwa kweempazamo.
I-Q2: Ngaba inokuxhasa ukusebenza okude?
A: Ewe, inokuxhotyiswa nge-actuator yombane kunye nemodyuli yokulawula kude ukuze kudityaniswe kuthungelwano lokuhambisa oluzenzekelayo.
I-Q3: Luluphi ulondolozo olufunekayo kwesi sixhobo?
A: Ngenxa yokutywinwa kwayo kunye noyilo lokucima i-arc, ukugcinwa kwesiqhelo kuncinci, ngakumbi ukuhlolwa kwamaxesha athile kweetheminali kunye nemeko yendlela yokusebenza.
