供应JG型6000V电机引接线

江苏春晨电缆有限公司供应JG型6000V电机引接线供应JG型6000V电机引接线，在三相四线电路中 相线与中线的电压为相电压；任意两相线间的电压为线电压；线电压是相电压的√3倍。流过各相负载的电流为相电流；流过相线中的电流为线电流。 In three-phase four wire circuit, the voltage between the phase line and the middle line is phase voltage, the voltage between any two phase lines is line voltage, and the line voltage is 3 times of the phase voltage. The current passing through the phase load is the phase current; the current passing through the phase line is a line current. 7. 变压器在电力系统中主要作用是什么？ 7., what are the main functions of transformers in power system 答：主要作用是变换电压，以利于功率的传输。在同一段线路上,传送相同的功率, 电压经升压变压器升压后，线路传输的电流减小,可以减少线路损耗，提高送电经济性，达到远距离送电的目的，而降压则能满足各级使用电压的用户需要。 Answer: the main role is to transform voltage to facilitate power transmission. On the same line, the same power is transmitted. After the voltage is boosted by the boost transformer, the transmission current of the line is reduced, which can reduce the loss of the line, improve the power supply economy, and reach the pur*e of long distance transmission, while the depressurization can meet the needs of the users at all levels.    标签： JG电机 JG硅橡 JGG高   JG电机引接线 JG硅橡胶电机引接线 JGG高压电机引接线   淮安市型电机引接线   淮安市型电机引接线厂家
