：为了使电机的旋转速度减半，把变频器的输出频率从50Hz改变到25Hz，这时变频器的输出电压就需要从400V改变到约200V2.当电机的旋转速度（频率）改变时，其输出转矩会怎样？变频器驱动时的起动转矩和最大转矩要小于直接用工频电源驱动。电机在工频电源供电时起动和加速冲击很大，而当使用变频器供电时，这些冲击就要弱一些。工频直接起动会产生一个大的起动起动电流。而当使用变频器时，变频器的输出电压和频率是逐渐加到电机上的，所以电机起动电流和冲击要小些。

Purpose of HYAT solid insulated filled cable: solid insulated filled cable is suitable for the urban telecommunication line of the local telecommunication network in the town of wuyu, and also for the special network line connecting to the public network. Mainly used for pipeline laying. The inner and outer surfaces of the cable core and the shield layer are filled with oil paste and poured to prevent water intrusion. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C.
Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyethylene or polyvinyl chloride thin sheath. Sheath thickness may depend on the basic cable outer diameter. 4, identification and marking: cable appearance with permanent identification mark, tag, at no more than alternate 1 m intervals between 5, sheathed communication cable tag contents are: the diameter of wire, wire on the quantity, type of cable, length, factory name and year of manufacture. 6. Armored communication cable electrical characteristics: the cable meets all the electrical requirements of the basic cable. 7. Cable length: mechanically protected cable is manufactured according to the standard length of the corresponding basic cable

绝缘材料：高密度聚乙烯或聚丙烯，按照全色谱标准标明绝缘线的颜色绝缘线对：把二根不同颜色的绝缘线按不同的节距扭绞成对，并采用规定的色谱组合以便识别线对。缆芯结构：以25对为基本单位，超过25对的电缆按单位组合，每个单位用规定色谱的单位扎带绕扎，以便识别不同的单位。
1图是漏电开关的零序电流互感器铁芯，可以看到火线和零线同时穿过铁芯。2图中的T是变压器，变压器有两个原边绕组，一个副边绕组。其中两个原边绕组线圈的缠绕方向一致，圈数也相等。当原边绕组1中流过电流I1时，按右手螺旋定则判断出变压器铁芯中的磁力线方向。请注意，2图中变压器T的原边绕组1和原边绕组2的电流方向是相反的，按右手螺旋定则，如果电流I1与I2大小相等方向相反，则变压器铁芯中没有磁力线，副边绕组当然也不会出现感应电流和感应电压。
