4069六反相器推荐工作条件电源电压范围3v-15v；输入电压范围0v-VDD工作温度范围：M类-55℃-125℃，E类-40℃-85℃功耗700mw静态电流25摄氏度时＜4uA；输出低电平电压0.05V；输出高电平电压VDD-0.05V；输入输出传播时间小于90ns内部结构及管脚序号见下图三。图三CD4069六反相器内部结构及管脚反相器基本概念以及与非门的关系反相器，顾名思义，“反”就是反过来的意思，就是和前一个不一样，“相”就是相位、状态的意思，反相器就是非门电路，也即输入低电平输出就是高电平，或者输入高电平输出就是低电平；这里所说的高低电平是相对的，即高与低之间相对而言，并不是具体的某一个值，比如3v也可能是高电平也可能是低电平。

　　4.充油电缆工作电容：平均值52±2nF/km5.充油电缆远端串音防卫度：150kHZ时指定组合的功率平均值大于69dB/km。控制电缆产品说明为适应市场需要，我厂在生产普通塑料绝缘控制电缆的基础上，近年来又开发了屏蔽和阻燃型控制电缆，深受广大用户欢迎。

　　加“ia、I、ZRI、IZ”是本安，加“N、NA、NH”是耐火、加(T、D）是对绞形式、屏蔽：P铜网屏蔽、P1镀锡屏蔽、P2铜箔屏蔽、P3铝箔屏蔽、PL铝箔屏蔽、P22屏蔽带铠装、P2/22铜箔屏蔽带铠装，耐压等级有：300/500V、300/300V、-0.5KV、-0.75KV、450/750V。
　　6.电力电缆 VV VLV VV22 VLV22 VV32 VLV32 1-240 （3*6+1）--（3*240+1）（4*6+1）-（4*240+1）（5*6+*240+1） NH耐火加大零线。

　　MHY32型弯曲半径不小于电缆直径的15倍。煤矿用控制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。



　　100对及以上线对的电缆加有1％的预备线对，但多不超过6对。缆芯内的间隙用石油膏填充。缆芯包带：用聚脂薄膜带绕包。屏蔽：用轧纹(或不轧纹)金属带，金属带纵包于缆芯包带之外。护套：黑色低密度聚乙烯。也可提供双层护套的电缆。

　　变频器与变频电机问电缆均需采用对称电缆结构，对称电缆结构有3芯和3+3芯两种，3+3芯电缆结构是将三大一小四芯绝缘线芯中第四芯(中性线芯)分解为三个截面较小的绝缘线芯，把三大三小线芯对称成缆，对于6/10kV变频电机专用电缆，该电缆结构与6/10kV普通电力电缆有所不同，普通电力电缆是将三根绝缘线芯。

且红笔所接的脚是K极，黑笔接的脚是G极，剩下一个脚就是A极了。如果测量的结果中，有两个脚的正、反向值都是几十至几百欧，那么这个可控硅就是双向可控硅。而且有一次测量的阻值比另一次测量的阻值稍大些，需要认真对比，阻值稍大的一次红笔接的为G极，黑笔所接为T1极，余下是T2极。双向可控硅图可控硅好坏的判断：就拿常见的额定6A以下的可控硅来说明：单向可控硅，将万用表打到RX1档红笔接K极，黑笔同时接通A极，并保持黑笔不离开A极情况下断开G极，指针应指示几十欧至一百欧，说明可控硅能被正常触发导通。
