Isicelo se-SPD kwiindawo eziphakamileyo eziphezulu
Njengomdlali wamazwe ngamazwe ekukhuselweni okukhuselekileyo, i-Prosurge inomthengi omkhulu kakhulu emhlabeni jikelele. Ngokomzekelo, sinamakhasimende amaninzi eMzantsi Melika apho edume kakhulu kwiindawo zakhe. Ngamanye amaxesha, sinokuthi abathengi babuze kuthi: Sifanele ukufakela isistim sokukhusela kwisixhobo esiphezulu kwi-2000m, ngaba kuya kuchaphazela ukusebenza kwe-SPD?
Ewe, lo ngumbuzo osebenzayo. Kwaye kweli nqaku, siza kuthetha ngalesi sihloko. Siza kuzisa iingcamango ezithile kwiingcali ezahlukeneyo kodwa ngokuqinisekileyo siqaphele ukuba le ndawo isadingeka ihlolwe ngakumbi kwaye ngoko inkcazelo esiyifakayo iyasebenza nje.
Yintoni ekhethekileyo malunga nokuLunga okuphezulu?
Umba wokhuseleko wokukhusela / ukhuselo lombane kwiindawo eziphakamileyo eziphakamileyo bekusoloko kuyisihloko esisebenzayo. Kwi-ILPS 2018 (i-Symposium yokuKhusela ukuKhanya kwiHlabathi jikelele), iingcali zokhuseleko ezikhuselayo zinengxoxo kwesi sihloko. Ke yintoni ekhethekileyo malunga nendawo ephezulu?
Okokuqala, makhe sijonge imozulu yemozulu ephambili yendawo eziphakamileyo:
- ukushisa okuphantsi kunye noshintsho olukhulu;
- uxinzelelo lomoya oluphantsi okanye ubuninzi bomoya;
- umbane welanga owongeziweyo;
- ukufuma okusezantsi ngokupheleleyo emoyeni;
- imvula encinci; iintsuku ezinomoya ngakumbi;
- ubushushu bomhlaba obuphantsi kunye nexesha elide lomkhenkce
Ukuguqulwa kweSixhobo soKhuseleko kwiSurgery kwiSicelo soMphezulu oPhezulu
Lo mahluko wemozulu unempembelelo kwi-SPD insulation. I-SPD ihlala isebenzisa izinto eziqinileyo kunye nomoya njengendawo yokukhusela. Njengoko ukuphakama kunyuka, i-SPD kufuneka inyuse ucoceko kunye nomgama we-creepage.
Kwi-SPD esele inoyilo olusisigxina kwaye ayikwazi ukutshintsha ukucocwa kwayo kunye nomgama we-creepage, kufuneka siqaphele ukuba: njengoko uxinzelelo lomoya luyancipha, i-voltage yokuphuka nayo iyancipha. Ukuze kuqinisekiswe ukuba i-SPD inokumelana ne-puncture eyaneleyo xa isetyenziswe kwindawo ephakamileyo yokuphakama, inokuqinisekiswa ngovavanyo. Ngaphandle koko, isakhiwo se-SPD kufuneka sitshintshwe ukuze kwandiswe imvume.
Ngaba i-Altitude iyakuchaphazela i-Iimp, i-Imax kunye ne-In?
Uxinzelelo lomoya ophantsi, ubushushu, ukufuma okupheleleyo kunye nezinye izinto kwindawo yokuphakama okuphezulu ziphantse zizimele kumbane weSPD okanye amandla akhoyo ngoku. Umbane / umthamo wangoku we-SPD uxhomekeke kuyilo lwangaphakathi lwesakhiwo semveliso kunye nokusebenza kwamacandelo ayo aphambili, aphantse angabinamsebenzi kwizinto zokusingqongileyo kwiindawo eziphakamileyo zokuphakama. Akukho mmiselo osemgangathweni ohambelanayo kunye nenkxaso yethiyori kwi-IEC ehambelanayo, imigangatho yesizwe kunye noncwadi oluhambelanayo.
Ngawaphi amanyathelo ovavanyo olongezelelweyo ekufuneka awathathe? Iimbono ezivela kwiiNgcali ze-UL
Ukusuka kwimbono yengcali ye-UL, fokanye ukuphakama okuphezulu kwezicelo zeSPD, sinokuthatha ezinye iimvavanyo. I-SPDs efakwe kunye nobude obungaphezulu kwe-2000 m kufuneka ihlolwe kwangaphambili ngaphambi kovavanyo lokunyuka: iisampuli ezintathu zifakwe kwibhokisi ye-pneumatic kwiiyure ze-168, kwaye uxinzelelo lomoya kufuneka luhambelane ne-IEC 60664-1. 2 kwaye wasebenzisa ubuninzi obuqhubekayo phezu kombane (MCOV).
