What are the main parameters of the transformer?
答：（ 1 ）额定电压；（ 2 ）额定电流；（ 3 ）额定容量；（ 4 ）空载电流；（ 5 ）空载损耗；（ 6 ）短路损耗；（ 7 ）阻抗电压；（ 8 ）绕组连接图、相量图及连接组标号。
Answer: (1) rated voltage; (2) rated current; (3) rated capacity; (4) no-load current; (5) no-load loss; (6) short circuit loss; (7) impedance voltage; (8) winding connection diagram, phasor diagram and connection group number.


9. 什么叫短路电流的热效应？
9. what is the thermal effect of short circuit current?
答： 在电路发生短路时，极大的短路电流将使导体温度迅速升高，称之为短路电流的热效应。
Answer: when the circuit is short circuited, the maximum short-circuit current will make the conductor temperature rise rapidly, which is called the thermal effect of short circuit current.


10. 什么叫涡流？涡流的产生有哪些害处？
10. what is the eddy? What are the harms of the formation of the eddy current?
答：当交流电流通过导线时，在导线周围会产生交变的磁场。交变磁场中的整块导体的内部会产生感应电流，由于这种感应电流在整块导体内部自成闭合回路，很像水的旋涡，所以称作涡流。涡流不但会白白损耗电能，使用电设备效率降低，而且会造成用电器（如变压器铁芯）发热，严重时将影响设备正常运行。
Answer: when alternating current passes through a conductor, alternating magnetic field will be generated around the wire. The inner part of the whole conductor in the alternating magnetic field produces an induction current, which is called a vortex, so it is called a eddy because the induction current becomes a closed loop in the whole conductor. The eddy current will not only consume electrical energy, but also reduce the efficiency of the use of the electrical equipment, and will cause the heating of the electric appliance (such as the transformer core), which will affect the normal operation of the equipment.


11. 二次回路的定义和分类是什么？
11. what are the definitions and classifications of the two circuits?
答：二次回路用于监视测量仪表，控制操作信号，继电器和自动装置的全部低压回路均称二次回路，二次回路依电源及用途可分为：
Answer: the two circuit is used to monitor the measuring instrument, control the operation signal, and all the low-voltage circuits of the relay and the automatic device are called two circuits, and the two circuits can be divided into the power supply and the use.
（ 1 ）电流回路；
(1) current circuit;
（ 2 ）电压回路；
(2) voltage circuit;
（ 3 ）操作回路；
(3) operation circuit;
（ 4 ）信号回路。
(4) signal circuit.
