发电机维护保养与其他详尽负载维护保养各不相同。由于发电机的励磁电和电流量与一般机械设备高压开关柜的交流电流和工作标准电压距离十分大，我们在维护机器设备方面也有很大的区别。下面焦化发电机组厂家为您讲讲发电机应配备哪些维护措施

The generator maintenance is different from other detailed load maintenance. Due to the large distance between the excitation current and current of the generator and the AC current and working standard voltage of the high-voltage switchgear of general mechanical equipment, we also have great differences in the maintenance of machinery and equipment. The coking generator set manufacturer will tell you what maintenance measures the generator should be equipped with

1、纵差维护：电机转子绕阻及其小组出线双色过电流保护。

1. Longitudinal differential maintenance: motor rotor winding resistance and its group outgoing line two-color overcurrent protection.

2、打横差动保护：电机转子绕阻单相匝间过电流保护。仅有当单相电机转子绕阻有两个或好多个并接环城路造成2个或三个中性点输电线时，才可以拼装这类维护保养。

2. Horizontal differential protection: motor rotor winding single-phase interturn overcurrent protection. This type of maintenance can only be assembled when two or more single-phase motor rotor windings are connected to the ring road in parallel, resulting in two or three neutral transmission lines.

3、短路故障问题维护保养：发电机组电机转子电磁线圈的短路故障问题维护保养。

3. Maintenance for short circuit fault: maintenance for short circuit fault of generator set motor rotor solenoid coil.

4、励磁调节器控制电路接地保护：励磁调节器控制电路接地系统常见问题维护保养。

4. Earthing protection of excitation regulator control circuit: maintenance of common problems of excitation regulator control circuit earthing system.

5、低励和去磁维护保养：为了防止机发电机在低励（励磁电低于数据格式稳定限定相符合的励磁电）或去磁（励磁电为零）后从系统吸收消化许多功率因数角，对系统导致欠佳伤害，容量为100MW及以上的发电机均配备该维护机器设备。

5. Low excitation and demagnetization maintenance: in order to prevent the generator from absorbing and digesting many power factor angles from the system after low excitation (the excitation current is lower than the excitation current corresponding to the stability limit of the data format) or demagnetization (the excitation current is zero), resulting in poor damage to the system, generators with a capacity of 100MW and above are equipped with such maintenance machinery and equipment.

6、过压保护：用于发电机长久性超额定负荷运行时的数据信号维护保养。中小型发电机仅设置过负荷维护保养；机发电机应分别配备电机转子过压保护和励磁电流绕阻过压保护。

6. Overvoltage protection: It is used for data signal maintenance when the generator is operating under long-term overload. Only overload maintenance is set for small and medium-sized generators; The generator shall be equipped with motor rotor overvoltage protection and excitation current winding overvoltage protection respectively.

7、电机转子绕阻过电流量维护：当发电机纵向差动保护范围外造成短路故障问题，短路故障电子器件或高压隔离开关的维护保养拒动时，该维护作为外部短路故障问题的贮备，也作为纵向差动保护的贮备维护保养。

7. Maintenance of motor rotor winding resistance overcurrent: when short circuit fault is caused outside the range of generator longitudinal differential protection, and the maintenance of electronic components or high-voltage disconnectors with short circuit fault refuses to operate, the maintenance is used as a backup for external short circuit fault and also as a backup maintenance for longitudinal differential protection.

8、电机转子绕阻过压保护：用于防止所有负载突然缺失而产生的电机转子绕阻过压。小型风力发电和大中小型汽轮发电机组均装有过压保护，大小型汽轮发电机组一般不设过压保护。

8. Motor rotor winding over-voltage protection: used to prevent motor rotor winding over-voltage caused by sudden loss of all loads. Small wind power generation and large, medium and small steam turbine generator units are equipped with overvoltage protection, while large and small steam turbine generator units are generally not equipped with overvoltage protection.
