蔚诗贫2156电工里的字母都代表什么?越多越好 -
房钥忠15686315492 ______ U电压 I 电流 R 电阻 Z总电阻 C表示电容 S 表示视在功率 W表示瓦特 1千瓦=1小时1度电等等. AC 交流电 DC 直流电 FU 熔断器 G 发电机 M 电动机 HG 绿灯 HR 红灯 HW 白灯 HP 光字牌 K 继电器 KA(NZ) 电流继电器(负序零序) KD 差动...

蔚诗贫2156输出继电器英文怎样说? -
房钥忠15686315492 ______ 输出继电器的说法不够准确,通常应该是输出接触器,英文是output contact.因为,作为继电器一般只是起中间控制作用,不作为输出用.因此,输出继电器只是国人的部分俗称,翻译为英文时应该还原其本来意思“输出接触器”,即:output contact.(注意:不是contactor,而是contact.contactor是触点).

蔚诗贫2156DC24V继电器的文字标号是什么?(国标)是KM,还是J,还是? -
房钥忠15686315492 ______ 继电器通用代号为K,可以加辅助代号,如KA.KM表示“接触器”.也不要用J,这是过去的拼音代号,现在与IEC接轨,统统用英文字母了.至于24VDC,那是继电器种类型号包含的内容,与图中代号无关 dc24v继电器,是由固定铁芯、动铁芯、弹簧、动触点、静触点、线圈、接线端子和外壳组成.线圈通电,动铁芯在电磁力作用下动作吸合,带动动触点动作,使常闭触点分开,常开触点闭合;线圈断电,动铁芯在弹簧的作用下带动动触点复位.触点又分为常闭和长开两种,一个公共点.

蔚诗贫2156继电器的脚为什么用30、85、86、87来表示 -
房钥忠15686315492 ______ 86.85是继电器线圈的引出脚. 30与87a常闭合.当86.85两端有直流电压时30与87a断开,与87合.继电器是一种电控制器件.它具有控制系统(又称输入回路)和被控制系统(又称输出回路)之间的互动关系.通常应用于自动化的控制电路中,它实际上是用小电流去控制大电流运作的一种“自动开关”.故在电路中起着自动调节、安全保护、转换电路等作用.

蔚诗贫2156中间继电器用什么英文字母代表?一般常用的“欧姆龙”4P 线圈为220V的中间继电器用什么表示? -
房钥忠15686315492 ______[答案] 欧姆龙的继电器型号很多,最好把你要查询的继电器型号规格写全,否则不好查询.

蔚诗贫2156继电器常开常闭触点字母符号 -
房钥忠15686315492 ______ NORMAL:常态的,OPEN:打开的,CLOSE:关闭的;电器触点中NO为常开触点NC为常闭触点

蔚诗贫2156中间继电器用什么英文字母代表? -
房钥忠15686315492 ______ OMRON/欧姆龙 型号 LY4NJ 线圈电源 220(V) 应用范围 中间不知道是否答非所问

蔚诗贫2156时间继电器文字符号为 -
房钥忠15686315492 ______ 时间继电器文字代号为 JS
