简介
TZH系列发电机按国标JB/T8981-1999制造，同时也符合IEC34-1国际标准，发电机防护等级IP21，绝缘等级为B级或F级。转子采用急极结构，性能更为可靠。
TZH系列发电机与STC系列发电机相比，具有五大特点：
1、复合式相复励结构，线路简单可靠，维护方便。
2、的动态性能，突加空卸负载时，电压波动极小。
3、强劲的启动能力，可直接启动70%额定功率的异步电动机。
4、准正弦的电压波形和良好的稳定性能，电脑也可以安全使用。
5、承担不平衡负载时，三想线电压不平衡度小于3%。
使用环境
在下列环境条件下，发电机能够额定运行。
1、海拔不超过1000米。
2、冷却空气温度258-313K（-15℃-40℃）。
3、相对湿度不超过90%。

INTRODUCTION
TZH series generators are made as per standard JB/T8981-1999,And in conformity to IEC34-1.
Protection class:IP21,Insulation Class B or F.The rotor structure is Concealed,Performance is more reliable.
TZH series generators have five advantages comparing with STC series generators.
Compound excitation,simple circuit,hith reliability,easy maintenance.
Excellent dynamic characteristics.when load or unload suddenly,the circuit’s light will not toinkle.
Strong staring system,even the motors only with its 70% capacity volume can be directly started and the swich will not trip.
Approaching sine voltage wave and regulated power supply,output voltage can be safely used on computers.
The deviation of the 3-phase line voltage will be less than 3% when the generators undertake unbalanced loading.

ENVIRONMENT CONDITIONS
Under the following environment,the generator could running continuously:
1.Altitude:not exceed 1000m.
2.Cooling air temperature:258-313K
   （-15℃-40℃）。
3.Relative air humidity:not exceed 90%.
