影响电伴热带质量的因素也是购买评判的标准

随着伴热带的市场越来越大,各地的厂家纷纷投入生产,但由于生产设备、技术水平、工艺条件的限制,产品质量也参差不齐。如果用户不慎使用了劣质的电伴热带,轻则短路跳闸,重则会引发伴热管线起火,甚至烧毁被伴热设备等重要部件这都是不可挽回的损失。

优质电伴热带

如何鉴别电伴(ban)(ban)热(re)带(dai)(dai)(dai)的(de)品质(zhi),成了选(xuan)(xuan)购(gou)电伴(ban)(ban)热(re)带(dai)(dai)(dai)的(de)头等大事。J9九游会AG 可以从(cong)以下几(ji)方(fang)面对电伴(ban)(ban)热(re)带(dai)(dai)(dai)的(de)品质(zhi)进行区分(fen)和判(pan)断:电伴(ban)(ban)热(re)带(dai)(dai)(dai)是扁形(xing)长带(dai)(dai)(dai),其导(dao)电线优(you)劣也直接关系到产品的(de)好(hao)坏,通常导(dao)电线芯(xin)用镀(du)(du)锡或镀(du)(du)镍铜丝绞合成型(xing),制造时(shi)除(chu)了要选(xuan)(xuan)择质(zhi)量好(hao)的(de)镀(du)(du)锡铜丝外,还必须考虑导(dao)电线芯(xin)表面护套对电伴(ban)(ban)热(re)带(dai)(dai)(dai)产生的(de)影响。

电(dian)(dian)(dian)(dian)(dian)(dian)伴(ban)热(re)(re)(re)带(dai)中(zhong)的(de)(de)(de)PTC芯(xin)带(dai)是电(dian)(dian)(dian)(dian)(dian)(dian)伴(ban)热(re)(re)(re)带(dai)的(de)(de)(de)核心部分,芯(xin)带(dai)的(de)(de)(de)好(hao)(hao)坏决定了电(dian)(dian)(dian)(dian)(dian)(dian)伴(ban)热(re)(re)(re)带(dai)在使用中(zhong)的(de)(de)(de)稳(wen)定性及使用寿命,其关键系数就(jiu)是启动(dong)电(dian)(dian)(dian)(dian)(dian)(dian)流大(da)小,启动(dong)电(dian)(dian)(dian)(dian)(dian)(dian)流是指电(dian)(dian)(dian)(dian)(dian)(dian)伴(ban)热(re)(re)(re)带(dai)接(jie)通电(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)时,瞬(shun)间产生的(de)(de)(de)最大(da)电(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)值。它对电(dian)(dian)(dian)(dian)(dian)(dian)伴(ban)热(re)(re)(re)带(dai)的(de)(de)(de)品(pin)质有着决定性意义,如果(guo)启动(dong)电(dian)(dian)(dian)(dian)(dian)(dian)流较大(da),那么单一电(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)伴(ban)热(re)(re)(re)带(dai)使用长(zhang)度就(jiu)会减短,这样每次(ci)启动(dong)时,还会破坏PTC层与导电(dian)(dian)(dian)(dian)(dian)(dian)线芯(xin)的(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)接(jie)触界面,缩(suo)短电(dian)(dian)(dian)(dian)(dian)(dian)伴(ban)热(re)(re)(re)带(dai)的(de)(de)(de)使用寿命,并存在很大(da)的(de)(de)(de)安全隐(yin)患。所以(yi)在选(xuan)购时,务必弄清启动(dong)电(dian)(dian)(dian)(dian)(dian)(dian)流这个参数,在条(tiao)件允许的(de)(de)(de)情况下,最好(hao)(hao)自己测量(liang)(liang),尽量(liang)(liang)选(xuan)购启动(dong)电(dian)(dian)(dian)(dian)(dian)(dian)流较小的(de)(de)(de)产品(pin),以(yi)免造(zao)成不必要(yao)的(de)(de)(de)损失。
