電(dian)加(jia)熱器（帶保護(hu)套(tao)）SRY6-1-380/6kw概述(shu)：

特(te)點(dian)：
1、電(dian)加(jia)熱元件采(cai)用(yong)仿(fang)制德(de)國(guo)產品制(zhi)造而成，電(dian)加(jia)熱器由加(jia)熱芯(xin)子(zi)和護(hu)套(tao)管組成，加(jia)熱芯(xin)子(zi)用(yong)管狀(zhuang)電(dian)加(jia)熱元件為(wei)熱源，護(hu)套(tao)管采(cai)用(yong)薄型(xing)不(bu)銹鋼(gang)管制(zhi)成(cheng)，接線裝置保護(hu)采(cai)用(yong)螺栓式罩殼密(mi)封，防水、防潮(chao)、防油(you)。
2、護(hu)套(tao)管與(yu)油(you)箱(xiang)體采(cai)用(yong)直管螺紋(wen)連(lian)接，密封性強，護(hu)套(tao)管將(jiang)芯(xin)子(zi)與(yu)被(bei)加(jia)熱油隔離，在更(geng)換(huan)電(dian)加(jia)熱器時(shi)，不(bu)需要放(fang)掉油箱(xiang)中(zhong)的油(you)液(ye)，僅需抽(chou)出加(jia)熱器芯(xin)子(zi)即(ji)可(ke)，維修(xiu)方便。
3、本(ben)型(xing)號(hao)電(dian)加(jia)熱器表面(mian)功(gong)率按(an)JBT2379-93標(biao)準(zhun)設(she)計(ji)，其(qi)表面(mian)功(gong)率應選擇(ze)在(zai)≤0.7W/cm2。

容(rong)器。用於信(xin)號(hao)耦(ou)合(he)、旁(pang)路(lu)的鋁電(dian)解(jie)電(dian)容(rong)器損壞(huai)後,可(ke)用
參(can)數相同(tong)的鉭(tan)性能(neng)更(geng)優的鉭(tan)電(dian)解(jie)電(dian)容(rong)器代(dai)換(huan)。電(dian)源(yuan)濾(lv)波(bo)電(dian)
耦(ou)電(dian)容(rong)器損壞(huai)後,可(ke)以(yi)用較(jiao)其(qi)容(rong)量(liang)略(lve)大(da)、耐壓(ya)值(zhi)與(yu)其(qi)相同(tong)
原電(dian)容(rong)器耐壓(ya)值(zhi))的同(tong)類(lei)型(xing)電(dian)容(rong)器更(geng)換(huan)。
(3)電(dian)容(rong)器代(dai)換(huan)時(shi)的註(zhu)意(yi)事(shi)項
①起(qi)定時(shi)作(zuo)用的電(dian)容(rong)器要盡量(liang)用原值(zhi)代(dai)替。
②不(bu)能(neng)用(yong)有極(ji)性電(dian)容(rong)器代(dai)替無極(ji)性電(dian)容(rong)器。
③代(dai)用(yong)電(dian)容(rong)器在耐(nai)壓(ya)和溫(wen)度(du)系數方面不(bu)能(neng)低(di)於原電(dian)容(rong)器
④各種(zhong)電(dian)容(rong)器都(dou)有(you)各(ge)自(zi)的個(ge)性,在使(shi)用(yong)中(zhong)壹(yi)般(ban)情況(kuang)下
量(liang)和耐(nai)壓(ya)等符合(he)要求(qiu),它們(men)之(zhi)間(jian)就可(ke)以(yi)進行(xing)代(dai)換(huan)。但是(shi)有些情
換(huan)效(xiao)果會不(bu)太好(hao),例(li)如用(yong)低(di)頻(pin)電(dian)容(rong)器代(dai)替高頻(pin)電(dian)容(rong)器後高頻(pin)損(sun)
比較(jiao)大(da)。嚴重(zhong)時(shi)電(dian)容(rong)器將(jiang)湧起(qi)到相應(ying)的功(gong)能(neng),但(dan)是(shi)高頻(pin)電(dian)容(rong)器
代(dai)替低(di)頻(pin)電(dian)容(rong)器
⑤操作時(shi)壹(yi)般首(shou)先取(qu)下原損(sun)壞(huai)電(dian)容(rong),然(ran)後接上(shang)新的電(dian)容(rong)
容(rong)量(liang)比較(jiao)小的電(dian)容(rong)器壹般(ban)不(bu)分極(ji)性,但是(shi)對於極(ji)性電(dian)容(rong)器壹定
接反。
(4)電(dian)解(jie)電(dian)容(rong)器使用(yong)時(shi)的註(zhu)意(yi)事(shi)項
①電(dian)解(jie)電(dian)容(rong)器由於有(you)正負(fu)極(ji)性,因此在(zai)電(dian)路(lu)中(zhong)使(shi)用(yong)時(shi)不(bu)能(neng)
倒(dao)連接。當電(dian)源(yuan)電(dian)路(lu)中(zhong)的濾(lv)波(bo)電(dian)容(rong)器極性接反時(shi),因電(dian)容(rong)器的湖
作(zuo)用(yong)大(da)大(da)降低(di),壹方面引(yin)起(qi)電(dian)源(yuan)輸(shu)出(chu)電(dian)壓(ya)波(bo)動(dong),另(ling)壹(yi)方面因反向(xiang)
電(dian)使(shi)此時(shi)相當(dang)於壹(yi)個(ge)電(dian)阻的電(dian)解(jie)電(dian)容(rong)發熱。當反向(xiang)電(dian)壓(ya)超(chao)過某(mou)
時(shi),電(dian)容(rong)器的反向(xiang)漏電(dian)電(dian)阻將(jiang)變得很小,這(zhe)樣(yang)通(tong)電(dian)工(gong)作(zuo)不(bu)久,即(ji)
使電(dian)容(rong)器因過(guo)熱而炸裂損(sun)壞(huai)。
②加(jia)在(zai)電(dian)解(jie)電(dian)容(rong)器兩端的電(dian)壓(ya)不(bu)能(neng)超(chao)過其(qi)允(yun)許工(gong)作電(dian)壓(ya),在(zai)設(she)
計(ji)實(shi)際電(dian)路(lu)時(shi)應(ying)根據(ju)具體情況(kuang)留有(you)壹(yi)定的余(yu)量(liang)。如果(guo)交(jiao)流電(dian)源(yuan)電(dian)壓(ya)
為(wei)220V,變壓(ya)器二次(ci)側(ce)的整(zheng)流後電(dian)壓(ya)為(wei)22V,此時(shi)選擇(ze)耐(nai)壓(ya)為(wei)2
的電(dian)解(jie)電(dian)容(rong)器壹般(ban)可(ke)以(yi)滿足要求(qiu)。但是(shi),假(jia)如交(jiao)流電(dian)源(yuan)電(dian)壓(ya)波(bo)動(dong)很
大(da)且有(you)可(ke)能(neng)上(shang)升到250V以(yi)上(shang), 選擇(ze)1.5倍(bei)或(huo)以(yi)上(shang)的耐(nai)壓(ya)值(zhi)。
③電(dian)解(jie)電(dian)容(rong)器在電(dian)路(lu)中(zhong)不(bu)應靠近(jin)大(da)功率發熱元件,以(yi)防因受(shou)
熱而使電(dian)解(jie)液(ye)加(jia)速(su)幹(gan)涸。

④對於有(you)正負(fu)極(ji)性信(xin)號(hao)的濾(lv)波(bo),可(ke)采(cai)取(qu)兩只電(dian)解(jie)電(dian)容(rong)器同極(ji)

2.4.4電(dian)容(rong)器應用(yong)電(dian)路(lu)
(1)固定電(dian)容(rong)器的應(ying)用(yong)
①LC諧振(zhen)電(dian)路(lu)。圖2-35(a)所(suo)示(shi)為並聯諧振(zhen)電(dian)路(lu),並聯諧振(zhen)
電(dian)路(lu)主要用(yong)於選頻(pin)電(dian)路(lu);圖2-35(b)所(suo)示(shi)為串聯諧振(zhen)電(dian)路(lu),串聯
諧振(zhen)可(ke)用於吸(xi)收(shou)電(dian)路(lu),其(qi)頻(pin)率為後,即(ji)後=2x√LC
②耦(ou)合(he)與(yu)旁(pang)路(lu)電(dian)路(lu)。如圖(tu)235(c)所(suo)示(shi),電(dian)容(rong)器C1、C3、C3
利用隔直(zhi)通(tong)交(jiao)特(te)性,可(ke)將(jiang)前後級(ji)直流隔斷(duan),將(jiang)前級(ji)交(jiao)流信(xin)號(hao)傳(chuan)遞到(dao)
後級(ji)(註(zhu):電(dian)解(jie)電(dian)容(rong)器在耦(ou)合(he)應用(yong)中(zhong),是(shi)正入(ru)負出(chu)還是(shi)負入(ru)正出(chu)取
決(jue)於前(qian)後級(ji)電(dian)位,即(ji)哪級(ji)電(dian)位高則(ze)正(zheng)極(ji)接哪級),C2、C4為旁(pang)路(lu)電(dian)
容(rong)器,利用隔直(zhi)流通(tong)交(jiao)流的特(te)性,可(ke)使交(jiao)流信(xin)號(hao)C直(zhi)接通(tong)過(guo),則(ze)R
對(dui)交(jiao)流無負(fu)反饋作用,使(shi)其(qi)對交(jiao)流放大(da)量(liang)增大(da)。
③濾(lv)波(bo)電(dian)路(lu)。如圖(tu)2-35(d)所(suo)示(shi),利用充(chong)放(fang)電(dian)特(te)性或通(tong)交(jiao)隔
直(zhi)特(te)性,濾(lv)除(chu)交(jiao)流成分(fen)得到直(zhi)流。
