浅谈用于爆炸性气体环境中电伴热带的试验方法

摘要

With the elevelopment of electricity with heat technology which is widely used for petroleum,chemical indusery,shipping and machinery,they become more improtant for test in explosive gas atmosphere.The paper states the principleand structure of automatic control electricity with heat zone and constant-power electricity with heat zone.According to self-characteristic of electricity with heat zone,the test method is adopted in explosine gas atmosphere.%随着其在石油、化工、船舶、机械等行业的广泛使用,电伴热带在爆炸性气体环境中的检验就显得尤为重要.本文简要阐述自控温电伴热带和恒功率电伴热带的原理和结构,根据电伴热带的自身特点设计其在爆炸性气体环境中采用的试验方法.
