防爆电伴热带选型和质量辨别
时(shi)间 : 2021-01-23 10:30 浏览量 : 52


  对于防爆电伴热带产品的定义,网上电伴热厂家给出的具体介绍都不一样,存在一定的差异。由于国内电伴热行业的发展历史很短,电伴热行业规范还不够完善,导致了对防爆电伴热带没有一个确切的定义。我公司拥有多项电伴热带专利,同时也拥有防爆电伴热带的认证合格证书,对防爆电伴热带有着更专业的理解和认识,防爆电伴热带又分为两种规格,一种是防爆电伴热带,一种是防爆加强型电伴热带。防爆电伴热带是指芯带外加一层绝缘层,绝缘层外加一层屏蔽层,而防爆加强型电伴热带是指芯带外加一层绝缘层,绝缘层外加一层屏蔽层,屏蔽层外加一层加强护套层防爆型电伴热带比普通的防爆电电伴热伴热带多了一层加强护套。

防爆电伴热带选型和质量辨别

  防爆电伴热带结构图:

  防爆电伴热带结构图(tu)

  ①铜芯导线:7×0.50;7×0.32;19×0.41;

  ②导(dao)电塑料层:普通PTC;阻燃PTC;含氟(fu)PTC;

  ③绝缘层(ceng):改(gai)良性聚(ju)烯烃(ting)(ting);阻燃聚(ju)烯烃(ting)(ting);含氟聚(ju)烯烃(ting)(ting);全氟材(cai)料;

  ④屏蔽(bi)层:镀锡软圆铜线(xian)(覆盖密度80%);

  防(fang)爆(bao)电(dian)伴(ban)(ban)(ban)热(re)(re)(re)带(dai)顾名思义是(shi)起到(dao)防(fang)爆(bao)的(de)作用,主(zhu)要是(shi)用于拥有防(fang)爆(bao)场合,比如:化(hua)工、油田(tian)、天然气等防(fang)爆(bao)区,如果采购(gou)不(bu)合格的(de)防(fang)爆(bao)电(dian)伴(ban)(ban)(ban)热(re)(re)(re)带(dai),有可能引起火(huo)灾甚至爆(bao)炸。防(fang)爆(bao)电(dian)伴(ban)(ban)(ban)热(re)(re)(re)带(dai)的(de)实(shi)际(ji)使用是(shi)不(bu)会出(chu)现事(shi)故(gu)的(de),出(chu)现事(shi)故(gu)主(zhu)要是(shi)由于外(wai)界的(de)原(yuan)电(dian)伴(ban)(ban)(ban)热(re)(re)(re)因而造成(cheng)的(de),如:1.电(dian)伴(ban)(ban)(ban)热(re)(re)(re)带(dai)使用时间(jian)长(zhang),出(chu)现老化(hua)导致(zhi);2.电(dian)伴(ban)(ban)(ban)热(re)(re)(re)带(dai)安装中(zhong)对伴(ban)(ban)(ban)热(re)(re)(re)带(dai)表面造成(cheng)了破(po)坏;3.防(fang)爆(bao)电(dian)伴(ban)(ban)(ban)热(re)(re)(re)带(dai)的(de)的(de)自身质量(liang)有问(wen)题等原(yuan)因。

  电伴热带(dai)质量分辨

  一(yi)、电(dian)伴热(re)带(dai)(dai)芯(xin)带(dai)(dai)导电(dian)铜(tong)(tong)丝电(dian)伴热(re)带(dai)(dai)是一(yi)扁(bian)形长(zhang)带(dai)(dai),其导电(dian)芯(xin)线(xian)优劣也(ye)直接(jie)关系到电(dian)伴热(re)带(dai)(dai)的(de)(de)好坏,通常(chang)导电(dian)芯(xin)线(xian)应用镀锡或镀镍铜(tong)(tong)丝绞合成(cheng)型,制造时,除(chu)要(yao)选择质(zhi)量好的(de)(de)镀锡铜(tong)(tong)丝外,还(hai)必(bi)需思索导电(dian)线(xian)芯(xin)外表状(zhuang)态对电(dian)伴热(re)带(dai)(dai)产生的(de)(de)影(ying)响,在线(xian)径的(de)(de)选择上也(ye)不(bu)能偷(tou)工减料,所以这样才(cai)为PTC芯(xin)带(dai)(dai)的(de)(de)质(zhi)量消(xiao)费打下(xia)了却(que)实的(de)(de)根底。

  二、电(dian)(dian)(dian)(dian)伴(ban)(ban)(ban)热(re)(re)(re)(re)(re)带(dai)启动(dong)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)电(dian)(dian)(dian)(dian)伴(ban)(ban)(ban)热(re)(re)(re)(re)(re)带(dai)PTC芯(xin)带(dai)是(shi)电(dian)(dian)(dian)(dian)伴(ban)(ban)(ban)热(re)(re)(re)(re)(re)带(dai)的(de)中心部位,普通(tong)厂家不(bu)电(dian)(dian)(dian)(dian)伴(ban)(ban)(ban)热(re)(re)(re)(re)(re)易控制其(qi)(qi)中心技(ji)(ji)术,其(qi)(qi)关键(jian)系数就是(shi)启动(dong)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大小(xiao)和衰退率,启动(dong)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)是(shi)指电(dian)(dian)(dian)(dian)伴(ban)(ban)(ban)热(re)(re)(re)(re)(re)带(dai)接通(tong)电(dian)(dian)(dian)(dian)源时(shi),霎时(shi)产生的(de)最大电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)峰值(zhi)。它对电(dian)(dian)(dian)(dian)伴(ban)(ban)(ban)热(re)(re)(re)(re)(re)带(dai)的(de)质量有着决(jue)议(yi)性意义,是(shi)反映电(dian)(dian)(dian)(dian)伴(ban)(ban)(ban)热(re)(re)(re)(re)(re)带(dai)制造(zao)技(ji)(ji)术程度(du)的(de)关键(jian)参(can)数。假定起(qi)动(dong)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)较大,那么单一(yi)电(dian)(dian)(dian)(dian)源的(de)电(dian)(dian)(dian)(dian)伴(ban)(ban)(ban)热(re)(re)(re)(re)(re)带(dai)运用长(zhang)度(du)相(xiang)应(ying)就会减(jian)短,同时(shi),每次(ci)起(qi)动(dong)时(shi),还会毁坏PTC层与导(dao)电(dian)(dian)(dian)(dian)线芯(xin)的(de)电(dian)(dian)(dian)(dian)接触界面(mian),缩(suo)短电(dian)(dian)(dian)(dian)伴(ban)(ban)(ban)热(re)(re)(re)(re)(re)带(dai)的(de)运用寿命(ming),并存在很(hen)大的(de)平安(an)隐患。目前(qian)国内(nei)大部分厂家的(de)产品起(qi)动(dong)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)普通(tong)在0.9~1.2A/m左右,低温电(dian)(dian)(dian)(dian)伴(ban)(ban)(ban)热(re)(re)(re)(re)(re)带(dai)起(qi)动(dong)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)均(jun)能(neng)控制在0.4A/m左右,中温电(dian)(dian)(dian)(dian)伴(ban)(ban)(ban)热(re)(re)(re)(re)(re)带(dai)起(qi)动(dong)电(dian)(dian)(dian)(dian)流(liu)(liu)(liu)均(jun)能(neng)控0.5A/,接近了(le)国际先进程度(du),抵达国内(nei)科(ke)技(ji)(ji)抢先程度(du)。
