Do you want to know why the series constant power electric heating strip cannot be cut arbitrarily
之前给大家分享的都是自限温伴热带的属性、功用等等，今天赋享的是另一种电伴热带——恒功率电伴热带，下面就让小助手给大家解说有关它们的属性引见，还有特别需求关注的学问点，请继续阅览吧。
电伴热带的常用型号可分为自限温电伴热带和恒功率电伴热带，自限温电伴热带是能够随意剪切运用的，但它的运用长度比拟短，不能超越100米；恒功率电伴热带又可分为并联和串联，并联型恒功率电伴热带是由于多个发热节在整个长度上并联相接，它能够依据实践长度剪切运用，但至少保存一个完好的发热节。
而串联恒功率电伴热带不可剪切，需定长定制消费，那么为什么串联恒功率电伴热带不可随剪切运用呢？缘由是串联恒功率电伴热带的线芯即发热芯是铜芯导线，每米的电阻和截面面积是依据设计请求特定的。假如剪短，单根电伴热带的电阻减小，依据P=U /R，功率会增大。串联恒功率电伴热带国度防爆认证技术指标每米功率小于30瓦，随意剪切后会招致每米功率增大，使伴热带短路，以至烧毁。
所以设计好的串联恒功率电伴热带，在技术上是决不允许随意剪切运用的。在选择串联恒功率这个型号的电伴热带时，需求计算好需求的长度，定长定制消费，长度可达上千米，主要合适于长输管道的伴热保温。
今日的分享到这里就完毕，欢迎您的来电咨询！
