自控溫伴熱電纜原理

    自控溫伴熱電纜原理

    自控溫電伴熱方案主要通過自控溫電伴熱線完成。自控溫電伴熱線由導電塑料和2根平行母線加絕緣層、金屬屏蔽網
、防fang腐fu外wai套tao構gou成cheng。其qi中zhong由you塑su料liao加jia導dao電dian碳tan粒li經jing特te殊shu加jia工gong而er成cheng的de導dao電dian塑su料liao是shi發fa熱re核he心xin。當dang伴ban熱re線xian周zhou圍wei溫wen度du較jiao低di時shi
，導dao電dian塑su料liao產chan生sheng微wei分fen子zi收shou縮suo，碳tan粒li連lian接jie形xing成cheng電dian路lu使shi電dian流liu通tong過guo
，伴ban熱re線xian便bian開kai始shi發fa熱re；而er溫wen度du較jiao高gao時shi，導dao電dian塑su料liao產chan生sheng微wei分fen子zi膨peng脹zhang

，碳tan粒li逐zhu漸jian分fen開kai
，導dao致zhi電dian路lu中zhong斷duan，電dian阻zu上shang升sheng
，伴ban熱re線xian自zi動dong減jian少shao功gong率lv輸shu出chu，發fa熱re量liang便bian降jiang低di。當dang周zhou圍wei溫wen度du變bian冷leng時shi，塑su料liao又you恢hui複fu到dao微wei分fen子zi收shou縮suo狀zhuang態tai，碳tan粒li相xiang應ying連lian接jie起qi來lai形xing成cheng電dian路lu，伴ban熱re線xian發fa熱re功gong率lv又you自zi動dong上shang升sheng。由you於yu整zheng個ge溫wen度du控kong製zhi過guo程cheng是shi由you材cai料liao本ben省sheng自zi動dong調tiao節jie完wan成cheng的de，其qi控kong製zhi溫wen度du不bu會hui過guo高gao也ye不bu會hui過guo低di。因yin此ci電dian伴ban熱re所suo具ju有you的de良liang好hao特te性xing是shi其qi他ta伴ban熱re係xi統tong所suo無wu法fa比bi擬ni的de。
