● ZN23-40.5 MV vacuum vacuum breaker o totonu MV masini tufatufaina o tolu-vaega AC 50Hz, fuaina voltage 40.5kV, e mafai ona fetaui ma JYN35/GBC-35 ituaiga ki kapeneta. E fetaui lelei mo le pulea ma le puipuiga i totonu o le eletise, fale fa'atau ma le tufatufaina atu o le eletise, aemaise lava mo nofoaga e masani ona faʻaogaina. O le vacuum circuit breaker o le ituaiga o taavale tosolima, ma le fausaga talafeagai, tausia lelei, saogalemu ma faʻatuatuaina faʻaoga.
1. O le vevela o le siosiomaga: pito i luga + 40 ℃, pito i lalo -15 ℃ (vaega malulu -25 ℃);
2. Maualuluga: e le sili atu i le 2000m;
3. Susū fa'atatau: e le sili atu le tau o aso ta'itasi nai lo le 95%, e le sili atu i le 90% le averesi masina;
4. mamafa mamafa ausa: tau averesi i aso taitasi e le maualuga atu nai lo 2.2 × 10 -3 Mpa, averesi masina e le sili atu nai lo 1.8 × 10-3 Mpa;
5. Ole malosi ole mafuie e le sili atu ile 8 tikeri;
6. Leai se afi, pa, faʻaleagaina, faʻamaʻi vailaʻau ma nofoaga faʻafefete tele.
1. O le aotelega o le fausaga o le vaeluaga o le taavale tosolima, faʻaaoga CT19 poʻo le CD10 masini, e mafai ona vaevaeina i JYN1 ma GBC ituaiga e lua.
2. O le tino o le ta'amilosaga o lo'o aofia ai le fa'avaa, insulator, vacuum interrupter, spindle ma fe'avea'i ma puipui fa'amau. O le pito i lalo o le faʻavaa o loʻo faʻapipiʻiina i uili e 4, mo le faʻaogaina o le vaʻavaʻa, ma isi itu taumatau o le faʻavaa o loʻo faʻapipiʻiina i le 6 insulator e pei o le lagolago, faʻaogaina le faʻaogaina ma le faʻaogaina o le lagolago, vacuum interrupter faʻapipiʻiina i le va o le malosi, lagolago static, o le vaeluaga o le matagaluega o loʻo i ai uiga o le laʻititi laʻititi, fausaga faigofie, ola umi o auaunaga, tausiga faigofie, leai se faʻalavelave faʻalavelave, leai se faʻaleagaina ma isi.
O le motusia matagaluega ua faaauupegaina i le ogatotonu faamauga longitudinal maneta vacuum interrupter, pe a tuueseese le malosi, fesootaiga static o motumotu interrupter ua tuuaia, o le a maua ai le avanoa le avanoa gaogao ma tineia pe a sili atu le zero. Ona o le fausaga faʻapitoa o le faʻafesoʻotaʻi, o le avanoa faʻafesoʻotaʻi o le a maua mai ai le maneta faʻaumi talafeagai i le taimi o fesoʻotaʻiga arc, o le arc e tufatufaina tutusa i luga o le faʻafesoʻotaʻi, faʻamautinoaina le maualalo o le arc voltage, ina ia faʻaitiitia le saoasaoa o le eletise eletise ma le potu arc ma maualuga. malosi toe fa'aleleia ala o fa'asalalauga arc, fa'aleleia le va'ava'a va'ava'ava'ava'a fa'ato'a fa'ato'a mafai nei ma le ola eletise.
