  6、使用特性:电缆导体的长期允许工作温度为70℃,电缆敷设温度应不低于0℃。电缆允许的弯曲半径:对有铠装或铜带屏蔽结构的电缆应不小于电缆外径的12倍。对有屏蔽层结构的软电缆,应不小于电缆外径的6倍。对无铠装层的电缆应不小于电缆外径的6倍。

  从那时起评估和寻找PVC料的替代物遂成为人们争论的焦点。早在1986年欧洲首先发现燃烧产物中含有的多溴二苯醚,四溴代双苯并二恶烷及四溴代双苯并呋喃等属于致癌物质。直至2001年英国又接连发现五溴二苯醚,十溴二苯醚在野生猎鹰蛋内的生物积累高出家养猎鹰蛋400倍。

就该起事件来看,作业者也曾“现场反复核对了53P屏位正面面板和压板、左侧端子排”,说明作为专业继电保护工,还是有很强的安全意识和业务素养,怕出现误短接误跳开关,风险辨识是很到位的。面对几乎一个模样的端子排,或许他也曾对检修间隔与运行间疑惑和担心过,可惜还是在源头上出了问题,在二次设备及回路工作安全技术措施单将措施填写错误,为下一步传动误短接端子埋下了隐患。其本人、班组成员同样缺乏一种质疑的精神,是习惯了还是不清楚?事件往往是这样的,一步错,步步错,直至扩大后才恍然醒悟。

(为什么要用M来表示D呢,因为我只转换12位,D是16位的)D换成M(12位数据的传输)M怎么能存储数据呢,因此M是个位软元件,只有断开(0)和闭合,而PLC数据都是二进制处理的,比如字软元件D是16位的,所以就能通过M来表示,一个D需要16个M来储存。b:这条指令时将数据D100的低8位传送到BFM的#16编号进行输出。c:将D100的低8位写到#16后,还要写高4位,为了不覆盖,得先把低8位保持,c的指令就是保持功能,H0004是16进制的数字4.转换成二进制就是100,对应b2b1b0;c的第一条指令就是将b2置1,第二条将b2置0,这样就完成#17的低8位保持功能了。

  我国国家标准GB12666.6(等同IEC331)将耐火试验分A、B两种级别,A级火焰温度950~1000℃,持续供火时间90min,B级火焰温度750~800℃,持续供火时间90min,整个试验期间,试样应承受产品规定的额定电压值。
