新型的ZW32真(zhen)空斷路(lu)器為什(shen)么多選用(yong)彈簧(huang)操動機構(gou)以取代電(dian)磁(ci)操作機構(gou)?
答:選用電(dian)(dian)(dian)(dian)(dian)磁(ci)操(cao)動(dong)(dong)(dong)機構的ZW32真(zhen)空斷(duan)(duan)路(lu)器(qi),其分合(he)閘(zha)動(dong)(dong)(dong)力由(you)直流電(dian)(dian)(dian)(dian)(dian)磁(ci)鐵(tie)(tie)產生(sheng),且操(cao)作功(gong)大,如常(chang)用的CD10和CD17型電(dian)(dian)(dian)(dian)(dian)磁(ci)操(cao)動(dong)(dong)(dong)機構在220V時的電(dian)(dian)(dian)(dian)(dian)流值分別為147A和128A。又由(you)于電(dian)(dian)(dian)(dian)(dian)磁(ci)鐵(tie)(tie)線圈(quan)中(zhong)的反電(dian)(dian)(dian)(dian)(dian)勢與鐵(tie)(tie)心運動(dong)(dong)(dong)速度有關,影響到真(zhen)空斷(duan)(duan)路(lu)器(qi)合(he)閘(zha)速度的提高(gao)及機電(dian)(dian)(dian)(dian)(dian)壽(shou)命(ming)等進一步的改善。故國外新型的真(zhen)空斷(duan)(duan)路(lu)器(qi),一般不再采(cai)用電(dian)(dian)(dian)(dian)(dian)磁(ci)操(cao)動(dong)(dong)(dong)機構。采(cai)用彈簧(huang)操(cao)動(dong)(dong)(dong)機構,特(te)點是:利用彈簧(huang)儲能,斷(duan)(duan)路(lu)器(qi)分合(he)操(cao)作僅由(you)功(gong)率很小的電(dian)(dian)(dian)(dian)(dian)磁(ci)鐵(tie)(tie)控(kong)制,對直流電(dian)(dian)(dian)(dian)(dian)源要(yao)求不高(gao)、速度特(te)性好(hao)、壽(shou)命(ming)長,故已廣泛取(qu)代電(dian)(dian)(dian)(dian)(dian)磁(ci)操(cao)作機構。
