TZH系列相复励三相同步发电机，是采用电抗移相、电流互感器反馈、电复合的不可控相复励励磁方式的自励恒压发电机。该发电机制造精良、可靠性高，具有自动调整电压的特性，性能指标高，调压精度达到±3%，维护简单，使用方便、可靠。

    本系列产品为三相，50赫芝，通常与柴油机配套组成移动电站机组，用以供给小型城镇、车站、农村、工厂或工地照明及动力用电。

Reactor phase shift, current transformer feedback, electrically coupled, non-controlled phase-compound excitation system has been used for phase-compound self-excited constant voltage 3-phase synchronous alternators Serires TZH.  They are noted for excellent construction, high reliability and the automatic voltage regulation.  Their performance index is good and precision of voltage regulation is ± 3 %.  The phase -compound-excited alternators are convenient in operation and easy to maintain.

  The frequency of this series alternator is at 50Hz.  They are usually equipped with diesel engine to become shift electric rigset.  Thus they can be used for lighting or as power units in small towns, factories, stations,countries and worksites
