I-126KV yangaphandle ye-SF6 Isaphuli seSekethe

I-126KV yangaphandle ye-SF6 ye-Circuit Breaker (imodeli ye-LW36-126) sisixhobo sokutshintsha i-high-voltage transmission-class eyenzelwe i-substations yegridi yamandla, iinkqubo zokuhanjiswa kwe-utility, kunye nothungelwano lombane omkhulu wezoshishino. Isetyenziselwa ngokubanzi ukulawula, ukukhuselwa, kunye nokutshintshwa komthwalo wangoku, ukugqithiswa kwangoku, kunye nephutha le-short-circuit current, kwaye inokusebenza njenge-tie circuit breaker kwiinkqubo zamandla ezidibeneyo.

Le 126KV yangaphandle ye-SF6 Circuit Breaker ithatha i-sulphur hexafluoride (SF6) igesi njenge-arc-quenching kunye ne-insulation medium, idibaniswe nekholomu enye, ikhefu elilodwa kwisakhiwo sepali. Ngethuba lokuphazamiseka, umgaqo wokucima i-arc ye-self-energy uvelisa ukuhamba kwegesi ye-speed-speed ngaphakathi kwegumbi le-arc ukupholisa ngokufanelekileyo kunye nokucima i-arc, ukuqinisekisa ukusebenza ngokuzinzile phantsi kweemeko eziphezulu.

Ixhotyiswe nge-CT eqhutywa yi-CT-driven motor spring operating mechanism kunye nenqanaba elithathu lenkqubo yokudibanisa oomatshini, i-LW36-126 ibonelela ngokusebenza okuchanekileyo kokutshintsha, ukuthembeka okuphezulu koomatshini, kunye nozinzo olugqwesileyo lwexesha elide lokufuna imeko yangaphandle.

Ulwakhiwo lweMveliso kunye noMgaqo wokuSebenza

I-126KV yangaphandle ye-SF6 ye-Circuit Breaker iqukethe igumbi lokucima i-arc eligcwele igesi ye-SF6, ukuhlanganiswa kwe-transformer yangoku, indlela yokusebenza, isakhiwo sokuxhasa i-insulating, kunye ne-steel enclosure system. Igesi ye-SF6 isebenza njenge-insulation kunye ne-arc-quenching medium, inika amandla aphezulu e-dielectric kunye nokubuyisela ngokukhawuleza emva kokuphazamiseka.

Ngexesha leemeko eziphosakeleyo, indlela yokusebenza iqhubela umnxibelelwano ohambayo ukuba ahlukane, ivelise ukuhamba kwegesi ye-SF6 ephezulu ngaphakathi kwegumbi le-arc. Oku kuhamba komoya kupholisa ngokukhawuleza kwaye kukhuphe i-arc, iqinisekisa ukuphazamiseka okukhuselekileyo kwee-voltage fault currents. Inkqubo yonxibelelano yoomatshini enamanqanaba amathathu iqinisekisa ukusebenza ngokuhambelana kwepali kunye nokuqhekeka okuphezulu.
