1. Ukukhethwa kwe-switchgear: i-high-voltage circuit breaker (i-voltage elinganiselwe, yamanje elinganiselwe, yamanje okuphukayo, ukuvala okulinganiselwe okwamanje, okushisayo

ukuzinza kwamanje, ukusimama okuguquguqukayo, isikhathi sokuvula, isikhathi sokuvala)

Izinkinga ezithile zokuphuka kwamandla e-high-voltage circuit breaker (umthamo wokuphuka osebenzayo umsinga wesekethe esifushane

isikhathi sokuphumula sangempela;izingxenye ze-DC kanye ne-AC zesilinganiso sokunqamuka kwesekethe esifushane;ukwephulwa kwe-coefficient kandunankulu;

ukuvala;amandla okuphuka ngaphansi kwezimo ezikhethekile)

Iswishi yokunqamula: isetshenziselwa ukuhlukanisa ukunikezwa kwamandla, ukushintsha umonakalo, nokuvula nokuvala isekethe yamanje encane

I-fuse ye-voltage ephezulu: isimiso sokusebenza;Izici zobuchwepheshe kanye nemingcele yobuchwepheshe (okukhulu ukugeleza kwamanje ekuncibilikeni, i

ngokushesha i-fuse izoxuba;i-current elinganisiwe ye-fuse, i-current rated of the melt, kanye nomthamo omkhulu wokuphuka, okungukuthi, umthamo);

Ihlukaniswe yaba amafuse aphezulu anomkhawulo wamanje futhi angakhawuleli okwamanje;Nquma i-voltage elinganisiwe kanye nesilinganiso samanje ngokuya nge-

okokusebenza okuvikelwe;Isilinganiso samanje sokuphuka sinquma uhlobo lwamanje olukhawula kanye nohlobo olungakhawuli lwamanje;Ukusebenza okukhethiwe

I-High-voltage load switch: ingaphula ukulayisha okuvamile kanye nokulayisha ngokweqile kwamanje, futhi ingavala nomjikelezo othile wesifunda esifushane, kodwa ayikwazi

ikhefu elifushane lesifunda samanje.Ngakho-ke, ngokuvamile isetshenziswa kanye ne-fuse.

2. Ukukhethwa kwe-transformer yamanje: izidingo eziyisisekelo (ukuzinza okushisayo nokuzinza okunamandla);I-transformer yamanje yokulinganisa (uhlobo,

amapharamitha alinganiselwe, izinga lokunemba, umthwalo wesibili, ukubalwa kokusebenza);I-transformer yamanje yokuvikela (uhlobo, imingcele elinganiselwe, ukunemba

ileveli, umthwalo wesibili, ukusebenza kwesimo esiqinile kwezinga le-P kanye neleveli ye-PR yesiguquli samanje nokusebenza kwesikhashana kweleveli ye-TP yamanje

i-transformer ekubalweni kokusebenza)

3. Ukukhethwa kwe-voltage transformer: izinhlinzeko ezijwayelekile zokukhetha (uhlobo nokukhethwa kwezintambo; ukuvuthwa kwesibili, i-voltage elinganiselwe, isigaba sokunemba kanye

umkhawulo wephutha);Isibalo sokusebenza (isibalo somthwalo wesibili, ukwehla kwamandla kagesi wesekethe yesibili)

4. Ukukhethwa kwe-reactor-limiting current: umsebenzi wayo ukukhawulela i-short-circuit current;I-reactor yebhasi, i-line reactor kanye ne-transformer circuit reactor;Ikona

ihlukaniswe njenge-reactor evamile ekhawulelayo kanye ne-split reactor;I-reactor ayinawo amandla okulayisha ngokweqile, futhi amandla amanje alinganisiwe abhekwa njenge

umkhawulo wamanje wamanje nganoma yisiphi isikhathi;Khawulela i-short-circuit current kunani elidingekayo ukuze unqume iphesenti lokusabela;Okuvamile

i-reactor ne-split reactor iqinisekiswa ngokuguquguquka kwe-voltage.

5. Ukukhethwa kwe-shunt reactor: donsa amandla asebenzayo we-capacitive wekhebula;Ixhunywe ngokuhambisana nolayini we-EHV;Ukukhethwa kwamandla okunxeshezelwa

6. Ukukhethwa kwe-reactor yochungechunge: khawulela i-inrush current (0.1% - 1% yezinga lokusabela);Ukucindezelwa kwe-Harmonic (izinga lokusabela elingu-5% no-12% lixutshwe)
