Imeko ye-Ambient
Ubushushu be-Ambient: -25℃~+45℃, umndilili wemihla ngemihla: ≤35℃
Ukuphakama: 1000m(Standard);ingaya kuthi ga kwi-4500m ukulungiselela iodolo ekhethekileyo;
Ukufuma okuhambelanayo: umyinge wemihla ngemihla ≤ 95%, umyinge wenyanga ≤ 90%;
Ubunzulu benyikima≤8 degree;
Izihlandlo ezisebenzayo kufuneka zingabikho kwizinto ezitshisayo, ezinokutsha kunye nomphunga.
Umzekelo
Uphawu lweMveliso
I-switchgear yiyunithi yendibano kwaye i-breaker circuit ithatha imodeli yomgangatho wenqwelo yesandla.Ingumnikazi wokutshintsha ngokulula kunye nokutshintshiselana kakuhle emva kokuxhobisa nge-vacuum vacuum breaker yesekethe ephezulu.Indlela yokuqhubela phambili ye-screw nut ifakwe kwifreyimu yenqwelo yesandla yokuthintela ekusebenzeni kwempazamo kunye nokonakalisa indlela yokuqhubela phambili, inqwelo yesandla inokususwa ngokulula;Onke amanyathelo okusebenza anokwenziwa kwimeko yokuvala;Kunyanzelekile ukutshixa phakathi kokutshintsha okuphambili, inqwelo yesandla kunye nomnyango wepaneli ukuhlangabezana nokhuseleko oluhlanu;indawo ebanzi yokudibanisa iintambo ezininzi kwi-cubicle yentambo.I-Earthing switch isetyenziswa kwi-earthing kunye ne-loop yesiphaluka esifutshane, i-degree degree yokukhusela i-IP3X, i-IP2X phantsi kwemeko yokuvula.

Uphawu lolwakhiwo
I-switchgear iyahlula kwi-enclosure kunye ne-handcart, i-enclosure yenziwe nge-aluminium-zinc plated sheet sheet emva kokucutshungulwa ngumatshini we-CNC kunye nokugoba okuninzi, emva koko ihlanganiswe kunye neebholiti.Ke inamandla omatshini anamandla kwaye inokuqinisekisa ukucoceka kunye nenkangeleko entle.Ibandakanya indawo yokuhanjiswa, indawo yenqwelo yesandla, indawo yekhebula, idigri yokhuseleko yi-IP2X xa i-CB handcart ikwindawo yokuvula kunye novavanyo.
I-switchgear luhlobo lwentsimbi olukhuphayo, isekethe ephambili ithatha ukucutshungulwa kwe-composite insulation, ukusasazeka ngokukhawuleza kwezinye iindawo.I-CT kunye ne-earth switching zifakwe kwi-cable compartment kunye ne-busbar compartment.Iqondo lokhuselo lwe-enclosure yi-IP3X, ukhuseleko kunye nendawo enkulu yeentambo ezininzi.Uyilo lolwakhiwo lweVCB entsha egqunywe ngokupheleleyo okanye iSF6 CB kunye nendlela yokusebenza yasentlakohlaza yimodeli yekhonsoli edityanisiweyo kunye nokugqwesa okutshintshiselana kakuhle kunye nokutshintsha ngokulula.
