水电发电机II的基本工作原理

同步发电机S分为三种类型：涡轮发电机，水电根据所使用的不同主要移动器的发电机和柴油发电机。其结构中的共同点是除了使用永磁体产生磁场的小电动机，通过直流激励线圈产生一般磁场，并且将激励线圈放置在转子上，并且放置电枢绕组在定子上。因为励磁线圈的电压低，所以功率很小，只有两个出口，很容易通过滑环出线;虽然电枢绕组具有更高的电压和高功率，但大多是三相绕组，带有3或4个出口，将其放在定子上更方便。发电机的衔铁（定子）芯层用硅钢板层压以减少铁损。转子芯可以由整体钢块制成，因为通过它的磁通量保持不变。在大型电动机中，由于转子承受了强的离心力，因此转子的材料必须是高品质的钢。

水力发电厂的发电机是同步电动机，可以将主要动器（水轮机）的机械能转换成电能，这通过诸如电力传输线的设备发送给用户。我们知道导线切割磁力线可以产生诱导的电动势。将导线连接到闭环中，通过同步发电机电流，使用电磁感应原理将机械能转换为电能。将线放置在中空鼓的芯槽中，并且当被称为定子时固定芯。磁力线由磁极产生，当磁极被称为转子时旋转。定子和转子是发电机的最基本的部分。为了获得三相交流电流，每120度沿着定子芯的内圈放置三相绕组A-X，B-Y，并且在转子上存在激励绕组（也称为转子绕组）。通过刷子和滑动环的滑动触点，通过激励系统产生的直流电流被引入转子激励绕组以产生恒定的磁场。当转子被原子机拖动并旋转时，定子绕组连续地切割磁力线，并且在其上诱导电动势。线切割磁力线可以产生诱导电动势。 When the wires are connected into a closed loop, current flows through. The synchronous generator uses the principle of electromagnetic induction to convert mechanical energy into electrical energy. The wire is placed in the hollow barrel iron core slot, the iron core is fixed, called the stator. The lines of magnetic force are generated by magnetic poles, which rotate, and are called rotors. The stator and rotor are the most basic parts of a generator. In order to obtain three-phase alternating current, three-phase windings A-X, B-Y, C-Z are placed along the inner circle of the stator core every 120 degrees, and there are excitation windings (also called rotor windings) on the rotor. Through the sliding contact of the brush and the slip ring, the direct current generated by the excitation system is introduced into the rotor excitation winding to generate a constant magnetic field. When the rotor is dragged and rotated by the prime mover, the stator winding continuously cuts the magnetic lines of force, and electromotive force is induced in it.
