在電(dian)伴熱(re)(re)(re)系統工程中,經常使(shi)(shi)(shi)用(yong)電(dian)伴熱(re)(re)(re)溫度控(kong)制器來控(kong)制電(dian)伴熱(re)(re)(re)帶(dai)。對于自限電(dian)伴熱(re)(re)(re)帶(dai),應(ying)用(yong)溫控(kong)器可以(yi)有效節能,在達到(dao)相同(tong)伴熱(re)(re)(re)防凍效果的同(tong)時,減少(shao)電(dian)伴熱(re)(re)(re)帶(dai)的運(yun)行,進而(er)有效延(yan)長電(dian)伴熱(re)(re)(re)帶(dai)的使(shi)(shi)(shi)用(yong)壽命。對于恒功(gong)率加(jia)(jia)熱(re)(re)(re)電(dian)纜(lan),本(ben)發(fa)明(ming)可以(yi)有效控(kong)制溫度,使(shi)(shi)(shi)加(jia)(jia)熱(re)(re)(re)電(dian)纜(lan)不會(hui)因過熱(re)(re)(re)而(er)損壞,在地(di)面加(jia)(jia)熱(re)(re)(re)附近應(ying)用(yong)本(ben)發(fa)明(ming)可以(yi)節省大量電(dian)能。
在溫(wen)度(du)控(kong)制器(qi)(qi)的(de)(de)應(ying)用中,仍然注意(yi)到一(yi)些溫(wen)度(du)控(kong)制器(qi)(qi)可以直接(jie)(jie)(jie)(jie)連(lian)接(jie)(jie)(jie)(jie)到加熱電(dian)(dian)(dian)纜(lan),而(er)一(yi)些電(dian)(dian)(dian)加熱伴熱溫(wen)度(du)控(kong)制器(qi)(qi)不(bu)能直接(jie)(jie)(jie)(jie)連(lian)接(jie)(jie)(jie)(jie)到加熱電(dian)(dian)(dian)纜(lan)。應(ying)該注意(yi)區分它(ta)們。主要區別在于(yu)(yu),電(dian)(dian)(dian)熱調(diao)節器(qi)(qi)的(de)(de)自(zi)能接(jie)(jie)(jie)(jie)觸(chu)器(qi)(qi),可以直接(jie)(jie)(jie)(jie)操(cao)作強電(dian)(dian)(dian),但(dan)最大(da)電(dian)(dian)(dian)流(liu)通常為16A,如果(guo)自(zi)限溫(wen)度(du)電(dian)(dian)(dian)熱帶的(de)(de)最大(da)起動(dong)電(dian)(dian)(dian)流(liu)大(da)于(yu)(yu)16A,則該電(dian)(dian)(dian)熱調(diao)節器(qi)(qi)不(bu)能使用,恒功率(lv)發熱電(dian)(dian)(dian)纜(lan)的(de)(de)電(dian)(dian)(dian)力不(bu)得超過3.5KW。溫(wen)控(kong)器(qi)(qi)可能會因過電(dian)(dian)(dian)流(liu)而(er)燒損(sun)。 如果(guo)由(you)于(yu)(yu)熱需求電(dian)(dian)(dian)流(liu)必(bi)須超過16A,蕪湖(hu)佳宏(hong)新材料有限公司(si)的(de)(de)技術人(ren)員主張用溫(wen)控(kong)器(qi)(qi)操(cao)作接(jie)(jie)(jie)(jie)觸(chu)器(qi)(qi)的(de)(de)方法操(cao)作電(dian)(dian)(dian)熱帶,同樣(yang)可以起到較好的(de)(de)溫(wen)度(du)調(diao)節作用。
溫度(du)控制(zhi)器用于控制(zhi)伴(ban)熱介質的溫度(du),它按隔爆型(xing)防爆電器要求設計和制(zhi)造,和電源接線盒配套使用。
防爆溫(wen)(wen)(wen)度控(kong)制器中(zhong)(zhong)感溫(wen)(wen)(wen)接觸到(dao)的(de)被控(kong)介質溫(wen)(wen)(wen)度升高時,感溫(wen)(wen)(wen)包中(zhong)(zhong)的(de)液體受熱膨脹,當(dang)被控(kong)介質超過設定溫(wen)(wen)(wen)度時,觸點斷開,系(xi)統自動切斷電源(yuan)。
