你知道温度开关也叫热继电器吗
编辑:杭州有限公司   时间:2022-09-02

  温度(du)开关也叫热继电器(qi)。温度(du)开关具(ju)(ju)有体积(ji)小(xiao)、过流大(da)、不复(fu)位、性能(neng)稳定(ding)、安装方便(bian)、且具(ju)(ju)有一定(ding)范围的湿(shi)度(du)设置和承载能(neng)力可供(gong)选(xuan)择,以(yi)满(man)足客户(hu)的应(ying)用需求。

  温(wen)度开(kai)关广泛应用于:饮水机(ji)(ji)(ji)(ji)、热水器、三(san)明治烤(kao)面包机(ji)(ji)(ji)(ji)、洗碗机(ji)(ji)(ji)(ji)、干(gan)燥机(ji)(ji)(ji)(ji)、消毒柜、微(wei)波炉、电(dian)热咖啡壶、电(dian)煮锅、冰箱、空调(diao)、过胶(jiao)机(ji)(ji)(ji)(ji)、办(ban)公设备、汽车座位加热器等电(dian)热器具。

  温(wen)(wen)度(du)(du)开(kai)关(guan)在低温(wen)(wen)时(shi)(shi)处于导通(tong)状(zhuang)态,当(dang)温(wen)(wen)度(du)(du)升(sheng)到温(wen)(wen)度(du)(du)开(kai)关(guan)的(de)动(dong)作(zuo)温(wen)(wen)度(du)(du)时(shi)(shi),温(wen)(wen)度(du)(du)开(kai)关(guan)断(duan)开(kai);当(dang)温(wen)(wen)度(du)(du)降到动(dong)作(zuo)温(wen)(wen)度(du)(du)以下时(shi)(shi)温(wen)(wen)度(du)(du)开(kai)关(guan)又导通(tong)。测试温(wen)(wen)度(du)(du)开(kai)关(guan)的(de)好坏(huai),可用(yong)(yong)(yong)(yong)万用(yong)(yong)(yong)(yong)表电阻档(dang),把万用(yong)(yong)(yong)(yong)表的(de)两(liang)根表笔分别接(jie)温(wen)(wen)度(du)(du)开(kai)关(guan)的(de)两(liang)个引脚,在常温(wen)(wen)下万用(yong)(yong)(yong)(yong)表显示(shi)阻值(zhi)基本(ben)为(wei)0,然后(hou)用(yong)(yong)(yong)(yong)烧热的(de)电烙铁(tie)(20W以上的(de)烙铁(tie)即(ji)可以)给温(wen)(wen)度(du)(du)开(kai)关(guan)的(de)金属外(wai)壳加热大(da)约2~3min后(hou)(达到了温(wen)(wen)度(du)(du)开(kai)关(guan)的(de)动(dong)作(zuo)温(wen)(wen)度(du)(du))温(wen)(wen)度(du)(du)开(kai)关(guan)响一声,同时(shi)(shi)万用(yong)(yong)(yong)(yong)表的(de)显示(shi)阻值(zhi)应为(wei)无穷(qiong)大(da)。

  拿(na)开(kai)(kai)电烙(luo)铁,待温(wen)(wen)(wen)(wen)度(du)(du)开(kai)(kai)关的(de)(de)温(wen)(wen)(wen)(wen)度(du)(du)下降后,又(you)(you)可听到响(xiang)一声,同时万用(yong)表(biao)显(xian)示的(de)(de)阻(zu)值又(you)(you)为零。能有这样变(bian)化的(de)(de)温(wen)(wen)(wen)(wen)度(du)(du)开(kai)(kai)关就是好的(de)(de)。如果用(yong)万用(yong)表(biao)电阻(zu)档(dang)测温(wen)(wen)(wen)(wen)度(du)(du)开(kai)(kai)关的(de)(de)两根引(yin)出(chu)线不通;或者测量时通,而给温(wen)(wen)(wen)(wen)度(du)(du)开(kai)(kai)关加(jia)热很长(zhang)时间,温(wen)(wen)(wen)(wen)度(du)(du)开(kai)(kai)关也(ye)不断(duan),这样的(de)(de)温(wen)(wen)(wen)(wen)度(du)(du)开(kai)(kai)关就是坏的(de)(de)。

  使用温(wen)(wen)度(du)开关(guan)应(ying)选择(ze)(ze)动(dong)作(zuo)温(wen)(wen)度(du)与电(dian)(dian)热(re)器“维持”温(wen)(wen)度(du)相(xiang)同的,如电(dian)(dian)开水壶就可选择(ze)(ze)动(dong)作(zuo)温(wen)(wen)度(du)为100℃的温(wen)(wen)度(du)开关(guan)。另外,温(wen)(wen)度(du)开关(guan)所标(biao)注(zhu)的额定电(dian)(dian)压和(he)电(dian)(dian)流应(ying)略大于电(dian)(dian)热(re)器工(gong)作(zuo)时的电(dian)(dian)压和(he)电(dian)(dian)流。
