Kutetezedwa kwa Mphezi ndi Kuphulika Kwambiri kwa Mphamvu Yaikulu
GPAS ya LV Ground Potential Overvoltage Attack
GPAS ndi chipangizo choteteza mphezi chogwira ntchito zambiri komanso chogwira ntchito chomwe chimaphatikiza kuponderezedwa kwapansi ndi chitetezo champhamvu. Ikhoza kuchepetsa kwambiri kuwonongeka ndi kuwonongeka kwa nthaka yomwe ingathe kuwononga ndi kuwonongeka kwa arc pazida zikakumana ndi zoopsa zamphezi.
Mphezi ikawomba mwachindunji, ndodo yamphezi kapena maukonde oteteza mphezi amalumikizidwa, ndipo mphezi yamphamvu imalowa mu gridi yapansi. Pamene mizere yamagetsi imapangitsa kuti mphezi ziwonjezeke, mphamvu yamagetsi imalowa mu gridi yapansi kudzera muzitsulo zomangira mphezi. Pamene zida zosokoneza zamphamvu monga makina owotcherera zimagwira ntchito, mphamvu yosokoneza yomwe imapangidwa ndi iwo idzalowanso mu gridi yapansi. Kukhazikika kwamphamvu kungayambitse kutayika kwa data, kuwonongeka kwa zida, kudumpha kwa zida, kuwonongeka kwa insulation kapena kuyatsa pamakina amagetsi otsika.
GPAS ili ndi kudalirika kwakukulu komanso nthawi yayifupi yochitapo kanthu, yomwe imatha kudzipatula bwino mafunde amphezi, kuletsa mafunde amphezi kuti zisawononge maukonde otetezedwa kuchokera kumaneti oteteza mphezi, ndikupewa bwino kuchitika ngozi zopanga chitetezo monga moto ndi kuphulika.
LOPS ya MV Bus Overvoltage Protection
Chida cha LOPS low-voltage bus overvoltage suppression chida chimalumikizidwa mwachindunji molingana ndi basi, pogwiritsa ntchito matekinoloje monga owongolera othamanga, zopinga zamphamvu zopanda mphamvu, ma interceptors apamwamba kwambiri, komanso kupondereza kwa antiattack. Imawerengeredwa mwasayansi ndikupangidwa mwaluso. LOPS imagwiritsa ntchito bwino mawonekedwe a volt ampere, mphamvu yayikulu yotenthetsera, komanso kuthamanga kwachangu kwa ma interceptors opitilira muyeso, zopinga zopanda mzere, ndi zida zopondereza. Nthawi zambiri, kukhazikitsa mtengo wa LOPS pa 1.2 nthawi yamagetsi yamagetsi yamagetsi (yosinthika mwapadera) kumatha kukhala ndi zotsatira zabwino pakugwira ntchito.
LOPS imalumikizidwa mwachindunji mogwirizana ndi mabasi, pogwiritsa ntchito matekinoloje monga owongolera mwachangu, zopinga zamphamvu zopanda mphamvu, zolumikizira nsonga za overvoltage, ndi kuponderezana kwa antiattack. Imawerengeredwa mwasayansi ndikupangidwa mwaluso. LOPS imalipira zofooka monga SPD, kuphatikiza overvoltage chitetezo, ndi resistance capacitance mayamwidwe, kuthetsa kwathunthu vuto la overvoltage pa sing'anga voteji main busbar.
LOPT ya MV Overhead Lines Chitetezo cha Overvoltage
35kV ~ 6kV mizere yapamwamba nthawi zambiri imayika zomangira ZnO. Pali zolakwika zomwe zimayambitsa kudumpha, kusweka kwa mzere ndi kuzimitsa.
Chitetezo Chatsopano cha Mphenzi pa Mzere Wotumizira Kumwamba (LOPT) Kutengera pafupi ndi cathode effect, teknoloji yaying'ono yaying'ono yowomba ndi kuzimitsa, kuswa mphamvu zowonongeka za ZnO zomangirira, zimagwiritsa ntchito mfundo zamitundu yambiri yamagulu omwe amawombera ndi kuzimitsa, mapangidwe apadera kuti atalikitse ndi kupititsa patsogolo cholinga cha arc. kuzimitsa.
LOPT ili ndi maubwino monga otetezeka, odalirika, otalikirapo, komanso kukonza pang'ono. Imatha kutulutsa mphamvu yamphezi mwachangu, kuletsa kusweka kwa mphezi ndikupunthwa, komanso imakhala ndi ntchito zodziyeretsa komanso zodziyeretsa.
