天津電熱帶,天津電伴熱帶,自控溫電伴熱帶
一、電伴熱帶較大電路長度,這是什么意思? 電伴熱帶較大電路長度即一個電源點可帶動的電伴熱帶長度。自控溫電伴熱帶的較大長度(du)(du)是基(ji)于某一(yi)規格的斷路器的大小(xiao)再(zai)考慮一(yi)定的沖擊電(dian)(dian)流而定的。 而另一(yi)種恒功(gong)率(lv)電(dian)(dian)熱(re)(re)帶(dai)功(gong)率(lv)恒定,發熱(re)(re)溫度(du)(du)高。恒功(gong)率(lv)電(dian)(dian)伴(ban)熱(re)(re)帶(dai)隨著長度(du)(du)的增加,電(dian)(dian)伴(ban)熱(re)(re)帶(dai)尾(wei)端(duan)(duan)的壓降也(ye)將增加。根(gen)據電(dian)(dian)伴(ban)熱(re)(re)相(xiang)關標準,恒功(gong)率(lv)電(dian)(dian)伴(ban)熱(re)(re)帶(dai)尾(wei)端(duan)(duan)功(gong)率(lv)降不得超(chao)過輸入(ru)端(duan)(duan)的20%。因此此時的電(dian)(dian)伴(ban)熱(re)(re)帶(dai)長度(du)(du)就規定為恒定功(gong)率(lv)電(dian)(dian)纜的較大長度(du)(du)。
