HW8 uthotho lwesaphuli sesekethe jikelele (Apha ekubhekiselwa kuso njengesaphuli sesekethe). Ilinganiswe ngoku i-200-1600A yangoku, i-voltage esebenzayo i-AC 400V, i-690v. faka kwi-AC 50Hz, Isetyenziswa ikakhulu kuthungelwano lokuhambisa amandla. Isetyenziselwa ukuhambisa amandla. Ukukhusela izixhobo zesekethe kunye nokubonelela ngombane, zikhululwe kwi-overload, i-voltage yetyala, i-short circuit, umonakalo wefault yesigaba esisodwa. Lo mqhekezi wesekethe unenkangeleko yobugcisa, amandla aphezulu okuqhekeza, i-zero flash over. ube nomsebenzi ohlukeneyo wokukhusela obukrelekrele. Ingasetyenziswa njengokhuseleko olukhethiweyo, isenzo esichanekileyo, ukuphepha ukuphuma kombane ngokungeyomfuneko.

ukwandisa ukuthembeka konikezelo lwamandla. Le ngqungquthela yesiphaluka ingasetyenziswa ngokubanzi kwizikhululo zamandla. iifektri. imigodi kunye nezakhiwo zale mihla eziphakamileyo.
Ingakumbi inkqubo yokuhambisa amandla kwisakhiwo esikrelekrele, Kumandla omoya. amandla elanga kunye nenye iprojekthi eluhlaza nayo inoluhlu olubanzi lwezicelo.
Imveliso inokwamkela ipateni ephezulu yocingo okanye ipateni yocingo ephantsi; i-draw-out type breaker yesekethe inomsebenzi wokuzihlukanisa.
Ukuhambelana nomgangatho: GB14082.2, IEC60947-2.
Ubushushu bomoya we-Ambient yi-5℃~+40℃, ubushushu obuphakathi kuma-24h ngaphantsi kwe+35℃.
Qaphela: umda ophezulu udlula+40℃ okanye umda osezantsi ngaphantsi-5′℃ iimeko zokusebenza. umsebenzisi kufuneka kuthethathethwane nomzi-mveliso.

♦Ukuphakama kwendawo yofakelo akudluli kwi-2000m.
♦ Ukufuma okunxulumene ne-atmosphere kubushushu bomoya obukuleyo yi-+40′℃ ayidluli kwi-50%: Kwiqondo lobushushu elisezantsi linokuba nokufuma okuphezulu; Umzekelo oyena mndilili wenyanga emanzi kakhulu ubuninzi bokufuma obumalunga nama-90%, ngeli xesha, i-avareji yenyanga ubuncinci bobushushu yi-20℃+, Ngenxa yokutshintsha kobushushu ngamanye amaxesha kufuneka kuthathwe amanyathelo akhethekileyo okujiyisa.
♦ Amanqanaba ongcoliseko kwinqanaba3.

I-circuit breaker's Isiphaluka esiPhambili secandelo lofakelo yi-V. Xa isiphaluka esiphambili se-voltage yokusebenza elinganisiweyo ingaphantsi okanye ilingana ne-AC400V. isekethe yokulawula kunye nesekethe encedisayo yecandelo lofakelo ngaphandle kwe-Undervoltage coil tripping kunye nomlawuli okrelekrele we-coil yonikezelo lwamandla eprayimari ye-coil efanayo ne-breaker circuit. Ezinye zizonke: Xa isekethe ephambili yombane olinganisiweyo ungaphezulu kwe-AC400V kwaye ingaphantsi okanye ilingana ne-AC690V. Ulawulo lwesekethe kunye neesekethe ezincedisayo zidinga i-transformer yodwa ukuze igqume nge-loop ephambili. Kwaye i-voltage ephezulu yokusebenza kwisekethe yokulawula kunye nesekethe encedisayo yi-AC400V. Udidi lofakelo lwesekethe yolawulo kunye nesekethe encedisayo ll.
