国音殃1285配电室低压侧电表不装电流互感器可以吗 -
柏家竖19410875835 ______ 1,因为电缆流过的电流都很大,没有直接串联的电流表可用.2,分流器式电流表从技术难度和成本上都比不了互感器简单、廉价.所以装电流互感器是必须的.

国音殃1285那种电表不用安护感器 -
柏家竖19410875835 ______ 1. 标注有直接接线方式的电表可以不用安装电流互感器. 2. 必须接电流互感器的电表额定电流一般是1.5到6安.电流很小. 3. 望能采纳.

国音殃1285100A电表可不可以,不接互感器 -
柏家竖19410875835 ______ 电表额定工作电流就是100A了.只要用电负荷工作电流不大于100A就不用接电流互感器了.直接读数即可.

国音殃1285换其他品牌的电表可以不换电压互感器和电流互感器吗 -
柏家竖19410875835 ______ 可以!但是,不同电能表的输入电流范围可能不同,这一点要注意.只要输入电流范围与互感器的输出电流范围相匹配,就没有问题.

国音殃12853*3(6)A智能电表不接互感器可以吗 -
柏家竖19410875835 ______ 不接互感器当然可以.只是允许电流很小.不能超过6A.

国音殃1285接三相电表要用互感器吗 -
柏家竖19410875835 ______ 要看你的负载有多大.负载大了,最好用互感器.

国音殃1285请问同事带互感器的电表,不用互感器可以用吗 -
柏家竖19410875835 ______ 带互感器是用电太大 电表受不了才用的,但用小电 是不会转的.就像水龙头慢慢滴 水表不转是同道理.

国音殃1285总电源空气开关是100安的,三相四线电表可以不接互感器吗 -
柏家竖19410875835 ______ 没有互感器,电表就没有信号.跟空气开关没关系,跟电流没关系

国音殃1285请三相四线电度表不安互感器可以吗? -
柏家竖19410875835 ______ 电度表有【直通式】和【互感器式】区分, 直通式电度表不用接互感器.

国音殃1285带互感器的三相四线电表.可是不要互感器.能够直接接线吗 -
柏家竖19410875835 ______ 可以的,S1进S2出.不过没有那么灵便了,单相电电表不走,电工可能不愿意这么干.可以做直通表使用,但是负荷电流不能超过电表的额定电流.使用时首先用短接线将电表的1、2孔,4、5孔,7、8孔互相短接,电源三相和零线分别接电表的1、4、7、10(N)孔,电表的3、6、9、10(N)孔接负载.
