Generator set find out how to avoid wet generator set in humid climate:

1.负载单调方法：

1. Load monotonic method:

假设表面只潮湿，负载单调可以单调。单调时，发电机组可以在50%的额定电流负载下工作。 然后将额定电流增加65%、85%和100%。每个阶段的负荷为4到5小时。 每个绕组的绝缘电阻应在单调过程中及时检测。绝缘电阻值满足要求后，可间歇单调，一般检测发电机组。

Assuming that the surface is only wet, the load can be monotonous. When monotonous, the generator set can work under 50% of the rated current load. Then increase the rated current by 65%, 85% and 100%. The load of each stage is 4 to 5 hours. The insulation resistance of each winding shall be timely detected in the monotonous process. After the insulation resistance value meets the requirements, the generator unit can be inspected intermittently and monotonously.

2.冷操作方法：

2. Cold operation method:

在AVR当电源线断开时，长期放置在灰尘或潮湿环境中的发电机组可搁置约10分钟。这可能足以单调绕组表面，并将绝缘电阻提高到1兆欧元以上。 该设备可恢复正常运行。

In AVR, when the power line is disconnected, the generator set that has been placed in the dust or humid environment for a long time can be set aside for about 10 minutes. This may be sufficient to monotone the winding surface and increase the insulation resistance to more than 1 trillion euros. The equipment can resume normal operation.

3，热风法：

3. Hot air method:

拆下发电机组的所有盖板，排出湿空气。用吹风机从发电机组进气口吹入。请注意，热源和绕组应至少保持300mm，控制绕组的表面温度，避免过热和绝缘损坏。绕组表面温度不得超过855°C，入口不得超过90°C,连续吹气半小时，记录绝缘电阻值。当值大于指定值时，单调过程完成。取下吹风机，盖上所有盖子，再试一次。

Remove all covers of the generator set and discharge the wet air. Blow in from the air inlet of the generator set with a blower. Please note that the heat source and winding shall be kept at least 300mm, and the surface temperature of the winding shall be controlled to avoid overheating and insulation damage. The winding surface temperature shall not exceed 855 ° C and the inlet temperature shall not exceed 90 ° C. the air shall be continuously blown for half an hour and the insulation resistance value shall be recorded. When the value is greater than the specified value, the monotonic process is completed. Remove the hair dryer, cover all the covers, and try again.

四、短路电流单调：

4、 Short circuit current monotonous:

一是机组机电设备安全工作，确保发电机组安全工作。发电机组的输出端通过短路片短路，所使用的短路片应能机组的额定电流。断开AVR并切换到外部0~24V调度直流电源电压，使定子每相电流达到额定电流的50-70%。每30分钟停止一次，切断外部激励电源，检查并记录绝缘电阻值。假设绝缘电阻值大于规定值，则可以移除外部直流电源，并且可以重新衔接并重新调试AVR。发电机组可以在额定速度下工作，但速度应保持稳定，以避免温度不稳定。

First, the safety work of the electromechanical equipment of the unit shall ensure the safe work of the generator unit. The output end of the generator set is short circuited through the short-circuit piece, and the short-circuit piece used shall be able to meet the rated current of the unit. Disconnect the AVR and switch to the external 0 ~ 24V dispatching DC power supply voltage to make the stator current of each phase reach 50-70% of the rated current. Stop once every 30 minutes, cut off the external excitation power, check and record the insulation resistance value. Assuming that the insulation resistance value is greater than the specified value, the external DC power supply can be removed, and the AVR can be re connected and re commissioned. The generator set can work at the rated speed, but the speed shall be stable to avoid temperature instability.
