辛温唯4176380电焊机接线方法 -
计狭奔15614087507 ______ 380v电焊机接线方法电焊机接线实物图1、电焊机原边侧的电压如为380V,表示为一次线圈电压为380V,将三相电源中两根不同相的极接入即可.2、地线接电焊机外壳有接地标志的接线柱上,另一点接三相在...

辛温唯41765.5p水泵泵380V怎样接线 -
计狭奔15614087507 ______ 你看看电机接线图是星形接法还是三角形接法, 电机上有6个接线柱2个一组共3组,根据图示接三相线

辛温唯4176公司有个电机铭牌上写220V△接法380VY接法 请问我该怎么接?? -
计狭奔15614087507 ______ 如果你用220V作为电机电源你就用△接法,如果用380V做你的电机电源就用Y接法.接220V一半随电机会有一个接线图.

辛温唯4176一般来说三相电饼铛应该怎么接线 -
计狭奔15614087507 ______ 电饼铛三相电不需要接零线. 三相设备一般不接零线,但是外壳一定要可靠的接地线,这一点很重要,因为那是保护人体安全和设备发生问题时及时跳闸,避免重大损失的发生. 三相电的基本原理和接线方式及其注意事项: 接电机的话,要通过断路器、接触器、保护器或者软启动、变频器等实现一次、保护控制,电机绕组接法见图片. 其他负载送出三相380V电源,通过零线可以提供220V电源,只接两相可以供出380V电源,根据负载需要进行选择. 接三相电时,由于有相序,有可能电机反转,这时任意调整其中两相即可.

辛温唯4176三相异步电动机的接法与电压关系 -
计狭奔15614087507 ______ 1、星形接线:线电流I=220/Z,为什么线电流为I=220/Z,首先,此接法下线电流=相电流,只需计算相电流.由于星形接线有个中性点,此点的电压为零,ua+ub+uc=Um*sin(wt)+Um*sin(wt-120°)+Um*sin(wt+120°)=0,详细计算过程省略,相当于...

辛温唯4176380/660V 电机是怎样接线的? -
计狭奔15614087507 ______ 电机有6个接线柱上排三个下排三个,电源380V就把连片竖直连接用三个连片,电源660V把上面一排的三个接线柱连在一起下面进线.

辛温唯4176电动机点动控制电路图是什么样的? -

辛温唯4176电机直接启动实物接线图 -
计狭奔15614087507 ______ 没有控制变压器,指示灯必须是380V的. 这是直接使用380V作为控制电源的图. 运行的指示灯直接并在接触器的线圈上. 停止的指示灯通过常闭接点串在380V上. 这个是使用控制变压器的接线图.

辛温唯4176大家帮我看看,380V的电机,接哪里 -
计狭奔15614087507 ______ 接2、4、6.把N接到电机的外壳上(地线)若反转则任意两项对调!

辛温唯4176三相电机接成单相怎么接线?
计狭奔15614087507 ______ 小功率三相电机可改为单相电机,但功率要变小一点,A相作相线,C相作零线,B相接电容,电容回出接A相线,假若倒转,AB对换即可 380V电机除去接地线(一般是最粗最长的那个),还有3个头.用220V的火线地线接任意两个头.然后用电容的两个脚一头接在空着的头上,另一头接在220V的任意一个头上,如果发现电机转反了,就换一个头.
