　　常用的符 及单位①欧姆定律I=U/R(适用于电阻电路，如白炽灯)②电能计算W=P·t（W为我们常说的电度，P为功率多少瓦或千瓦，t为时间小时计量）例如一个220V,60W的白炽灯，在220V电压工作下。每晚用3小时，一个月用多少度电。　　当负载电阻远远小于电压线圈电阻时，应采用电压线圈后接法 。这时电压线圈两端的电压虽然等于负载电压，但电流线圈中的电流却等于负载电流与功率表电压线圈中的电流之和，测量时功率读数为负载功率与电压线圈功率之和。　　数字通讯RS485通讯连接提供串行异步半工RS458通讯接口，采用MOD-BUS-RTU协议，各种数据记息均可在通讯线路上传送。在一条线路上可以同时连接多达32个网络电力仪表，每个网络电力仪表均可以设定其通讯地址(Address No.)，不同系列仪表的通讯接线端子号码不同，通讯连接应使用带有铜网的屏蔽双绞线，线径不小于0.5mm。

　　首先，断路器在电路中主要是用于过电流保护，在电路有过载或短路情况发生时，产生电流过大，超过其承受电流适范围时，断路器切断电路，防止故障进一步扩大，这里一个关键的地方就是过电流。第二，空开选择一般是依据总电流的1.2~1.3倍,如果是电动机，就要考虑启动电流,一般是远远高于1.3倍，这有矛盾之处，所以，综上分析，配线断路器不宜用于保护电动机线路中。

　　如果主触点烧毁，触点虽然也可以更换，但因为曾经更换过一批效果不太好，一方面，好的触点成本不低，如果哪个坏更换那个，造成新旧触点搭配，使用寿命仍然不会太久，另一方面，更换过主触点的器耐用性比较差，因为有些器是紧密卡件互卡，拆开再装容易损毁卡点，所以也不建议更换。

批发韩国AND KOREA AD-4212C-301应用推荐　　1、万用表测电流，三相不平衡率不大于10%；2、摇表测绝缘，每相对地、相间均不小于0.5兆；3、电桥测直流电阻，三相不平衡率不大于2%；即首先用万用表去量电压以及电阻（没摇表的情况下），首先在电机电源侧UVW三相中选取两相，测量一下两端电压是否为380v（高于380V没事）中有时电压不导致的。　　电机额定功率即电动机的轴输出功率，也是负载计算时所采用的数据。P1在负载计算中作用不大，一般不再进行换算。例如一台小型电机的铭牌数据：额定功率250W，额定电压380V，额定电流0.85A，功率因数0.68。如果不算效率时，额定电流=250/(1.732*380*0.68)=0.56A，跟0.85A不符；如果算效率，额定电流=0.85=250/（1.732*380*0.68*效率）；由上式计算效率为：电动机效率=250/(1.732*380*0.68*0.85)=0.66。
　　4、输出特性（1）SSR给出的额定输出电流一般指常温下或常温到高温下的额定输出电流而且对大于10A的继电器还指带有规定散热器时的额定输出电流。对功率SSR，当工作温度上升或不带散热器时，输出电流相应下降。

 　　8、电动机扫膛产生扫膛的原因是：电机轴上支承圈磨损严重、转子铁心位移，或因其他原因使定子铁心位移，造成电机锥形转子与定子间隙太小发生扫膛。电机严禁“扫膛”，当发生扫膛后，应拆下支承圈进行更换，定子转子锥面之间的间隙使之均匀，或送到维修厂进行修理。
