定子绕组短路，在短路电压的作用下产生回路电流，使匝间短路发展为单相接地短路和中间短路。当定子绕组多相短路对机组有害时，短路电流会导致机组烧毁。
Short circuit of stator winding generates circuit current under the action of short circuit voltage, causing inter turn short circuit to develop into single-phase ground short circuit and intermediate short circuit. When the multiphase short circuit of the stator winding is harmful to the unit, the short-circuit current can cause the unit to burn out.
励磁电流会急剧下降或消失，机组从系统中吸收大量功率，柴油发电机组由同步运行变为异步运行，导致系统电压下降，严重时系统崩溃。
The excitation current will drop or disappear sharply, the unit will absorb a large amount of power from the system, and the diesel generator set will change from synchronous operation to asynchronous operation, which will cause the system voltage to drop, and in serious cases, the system will collapse.
励磁电路将接地。发电机励磁回路有两种接地情况:一点接地和两点接地。一般来说，当励磁回路发生少量接地时，发电机不会受到严重危害。但如果发电机维护不及时，可能导致两点接地，破坏转子磁通平衡，引起发电机强烈振动，烧毁转子绕组。
The excitation circuit will be grounded. There are two grounding conditions for the generator excitation circuit: one point grounding and two point grounding. Generally speaking, when a small amount of grounding occurs in the excitation circuit, the generator will not be seriously endangered. But if the generator is not maintained in a timely manner, it may lead to two point grounding, damage the rotor magnetic flux balance, cause strong vibration of the generator, and burn out the rotor winding.

该装置将产生过电压。当发电机在运行中突然空载时，如果柴油发电机组不及时修复，可能会因调速系统惯性大而产生过电压，导致发电机组绝缘层损坏。
This device will generate overvoltage. When the generator is suddenly unloaded during operation, if the diesel generator set is not repaired in time, it may generate overvoltage due to the large inertia of the speed governing system, resulting in damage to the insulation layer of the generator set.
该单元将过载。柴油发电机组过载是指发电机运行超过额定容量。如果发电机维护不及时，短时超负荷运行会造成发电机定子绕组温度升高，加速绝缘部分老化，缩短发电机使用寿命。如果运行时间过长，可能会导致发电机定子绕组烧毁，从而导致发电机无法发电。
The unit will be overloaded. Overload of diesel generator set means that the generator operates beyond the rated capacity. If the generator is not maintained in a timely manner, short-term overload operation will cause the temperature of the generator stator winding to rise, accelerate the aging of the insulation part, and shorten the service life of the generator. If the operating time is too long, it may cause the generator stator winding to burn out, resulting in the generator being unable to generate electricity.
如果柴油发电机组维护不及时，定子会过流。定子过电流通常由外部短路或系统振荡引起。如果发电机没有及时维护，当发电机定子温度升高时，会加速绕组绝缘部分的老化；严重的话会导致其他故障。
If the diesel generator set is not maintained in time, the stator will overflow. Stator overcurrent is usually caused by external short circuits or system oscillations. If the generator is not maintained in a timely manner, when the temperature of the generator stator increases, it will accelerate the aging of the insulation part of the winding; In severe cases, it can lead to other malfunctions.
