I=800KVA÷1.732÷6KV=76.9A。估算："容量除以电压值"：800KVA÷6KV=133。"其商乘六除以十"：133*6÷10=79.8A。（估算值和公式计算值有误差）。再比如计算二次测额定电流。公式计算：800KVA=1.732*I*0.4KV。I=800÷1.732÷0.4=1154.7A。估算：800÷0.4=2000，,2000*6÷10=1200A。此口诀适用于任何等级的变压器。

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. Structure: wire: annealed bare copper wire, copper wire diameter 0. 32, 0. 40, 0. 50, 0. 60, 0. 70, 0. 80, 0. 90 (mm). Insulating material: high density polypropylene or polypropylene, colour of the insulated wire as indicated by full chromatograph. Pair of insulated wires: twist two different colored insulated wires into pairs at different pitch and use the specified chromatographic combination to identify pairs. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs of cables with more than one pair of cables plus 1% of the reserve pair, but not more than 6 pairs. The gap in the core is filled with oil paste. Core tape: wrap with a polygrease film tape. Shielding: metal strip with or without striping, which is longitudinal wrapped outside the core of the cable. Sheath: black low density polymer. Double sheathed cables can also be provided. Identification and marking: cable outer surface sexual identification mark, mark at no more than alternate 1 m intervals, tag contents are: the diameter of wire, line number, cable type, factory name and year of manufacture, marking at no more than alternate 1 m intervals to mark on the surface, but with the tag stagger. Other structures: according to the needs of users, we can provide armored cables HYAT53, HYAT55 and high frequency isolation cables YATG with strengthened mechanical protection layer.

，一般在长期使用的情况下，电机原本的星形接法不要改为三角形接法，改为三角形电压必定升高（相电压升高约1.73倍），长时间会烧坏电机。4，一般长期使用情况下，电机原本的三角形△接法不要改为星形接法，改为星形电压必定降低，带额定负载时属于过载现象，严重时会烧坏电机。5，星三角降压启动时，改变接线方式是因为启动时间很短，但是电流却下降到原来的1/3很明显。三相异步电动机出厂时候一般都已经接好绕组或者端盖上有接线电路图，严格使用。
