1. Ukukhethwa kwesixhobo sokutshintsha: i-high-voltage circuit breaker (i-voltage elinganisiweyo, ireyithingi yangoku, i-breaking current, ireyithwe ngokuvala ngoku, i-thermal

uzinzo lwangoku, uzinzo oluguqukayo lwangoku, ixesha lokuvula, ixesha lokuvala)

Iingxaki ezithile zokuqhawuka komthamo we-high-voltage circuit breaker (umthamo wokuqhawula osebenzayo ngumbane wesiphaluka esifutshane

ixesha lokuphumla langempela;amacandelo e-DC kunye ne-AC ombane ofikelelweyo we-short-circuit breaking current;ukwaphulwa komlinganiso wenkulumbuso;

ukuvalwa;ukuqhawuka kwamandla phantsi kweemeko ezizodwa)

Iswitshi yokuqhawula: isetyenziselwa ukwahlula unikezelo lwamandla, tshintsha umonakalo, kwaye uvule kwaye uvale isekethe encinci yangoku

I-fuse yombane ophezulu: umgaqo wokusebenza;Iimpawu zobugcisa kunye neeparitha zobugcisa (inkulu ikhoyo ngoku equkuqelayo kwi-melt, i

ngokukhawuleza i-fuse iya kuxuba;i-current rated of the fuse, i-current rated current of the melt, kunye neyona ndlela iphezulu yokuphuka, oko kukuthi, umthamo);

Ukwahlula kwi-fuses yangoku kunye ne-non-current-limiting high-voltage fuses;Qinisekisa i-voltage elinganisiweyo kunye ne-rerated current ngokuhambelana ne-

izixhobo ezikhuselweyo;Ireyithi yokuqhawula ngoku inquma uhlobo lwangoku lokukhawulela kunye nohlobo olungekho lwangoku;Ukusebenza okukhethiweyo

Iswitshi yomthwalo wevoltage ephezulu: inokwaphula umthwalo oqhelekileyo wangoku kunye nomthwalo ogqithileyo wangoku, kwaye inokuvala isiphaluka esithile esifutshane sangoku, kodwa ayikwazi.

ikhefu elifutshane lesekethe yangoku.Ngoko ke, idla ngokusetyenziswa kunye ne-fuse.

2. Ukukhethwa kwe-transformer yangoku: iimfuno ezisisiseko (ukuzinza kwe-thermal kunye nokuzinza okunamandla);Isiguquli sangoku somlinganiselo (uhlobo,

iiparamitha ezilinganisiweyo, inqanaba lokuchaneka, umthwalo wesibini, ukubala ukusebenza);I-transformer yangoku yokukhusela (uhlobo, iiparamitha ezilinganisiweyo, ukuchaneka

inqanaba, umthwalo wesibini, ukusebenza ngokuzinzileyo kwenqanaba le-P kunye nenqanaba le-PR lenguqu yangoku kunye nokusebenza okwethutyana kwenqanaba le-TP langoku

isiguquli ekubaleni ukusebenza)

3. Ukukhethwa kwe-voltage transformer: izibonelelo ngokubanzi zokukhetha (uhlobo kunye nokukhethwa kweengcingo; ukujika kwesibini, umbane olinganisiweyo, udidi oluchanekileyo kunye

umda wemposiso);Ubalo lokusebenza (ukubalwa komthwalo wesibini, ukuhla kwamandla ombane wesekethe yesibini)

4. Ukukhethwa kwe-reactor-miting current: umsebenzi wayo kukukhawulela i-short-circuit current;I-reactor yebhasi, ireactor yomgca kunye ne-transformer circuit reactor;Yi

ihlelwa njengesixhobo esixhaphakileyo somda wangoku kunye nereactor yokwahlulahlula;I-reactor ayinayo umthamo ogqithisiweyo, kwaye umsinga olinganisiweyo uthathwa njenge

ubuninzi obukhoyo bangoku nangaliphi na ixesha;Nciphisa i-short-circuit current kwixabiso elifunekayo ukumisela ipesenti yokusabela;Okuqhelekileyo

i-reactor kunye ne-split reactor ziqinisekiswa ngokuguquguquka kwamandla ombane.

5. Ukukhethwa kwe-shunt reactor: ukufunxa amandla e-capacitive reactive yentambo;Idityaniswe ngokuhambelana nomgca we-EHV;Ukukhethwa kwamandla embuyekezo

6. Ukukhethwa kwe-series reactor: ukunciphisa i-inrush current (0.1% - 1% yereyithi yokusabela);Ukunyanzeliswa kwe-Harmonic (izinga lokuphendula i-5% kunye ne-12% exutywe)
