發(fā)電機維護保養(yǎng)與其他詳盡負載維護保養(yǎng)各不相同。由于發(fā)電機的勵磁電和電流量與一般機械設(shè)備高壓開關(guān)柜的交流電流和工作標(biāo)準(zhǔn)電壓距離十分大，我們在維護機器設(shè)備方面也有很大的區(qū)別。下面焦化發(fā)電機組廠家為您講講發(fā)電機應(yīng)配備哪些維護措施

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、縱差維護：電機轉(zhuǎn)子繞阻及其小組出線雙色過電流保護。

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

2、打橫差動保護：電機轉(zhuǎn)子繞阻單相匝間過電流保護。僅有當(dāng)單相電機轉(zhuǎn)子繞阻有兩個或好多個并接環(huán)城路造成2個或三個中性點輸電線時，才可以拼裝這類維護保養(yǎng)。

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、短路故障問題維護保養(yǎng)：發(fā)電機組電機轉(zhuǎn)子電磁線圈的短路故障問題維護保養(yǎng)。

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

4、勵磁調(diào)節(jié)器控制電路接地保護：勵磁調(diào)節(jié)器控制電路接地系統(tǒng)常見問題維護保養(yǎng)。

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

5、低勵和去磁維護保養(yǎng)：為了防止機發(fā)電機在低勵（勵磁電低于數(shù)據(jù)格式穩(wěn)定限定相符合的勵磁電）或去磁（勵磁電為零）后從系統(tǒng)吸收消化許多功率因數(shù)角，對系統(tǒng)導(dǎo)致欠佳傷害，容量為100MW及以上的發(fā)電機均配備該維護機器設(shè)備。

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、過壓保護：用于發(fā)電機長久性超額定負荷運行時的數(shù)據(jù)信號維護保養(yǎng)。中小型發(fā)電機僅設(shè)置過負荷維護保養(yǎng)；機發(fā)電機應(yīng)分別配備電機轉(zhuǎn)子過壓保護和勵磁電流繞阻過壓保護。

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、電機轉(zhuǎn)子繞阻過電流量維護：當(dāng)發(fā)電機縱向差動保護范圍外造成短路故障問題，短路故障電子器件或高壓隔離開關(guān)的維護保養(yǎng)拒動時，該維護作為外部短路故障問題的貯備，也作為縱向差動保護的貯備維護保養(yǎng)。

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、電機轉(zhuǎn)子繞阻過壓保護：用于防止所有負載突然缺失而產(chǎn)生的電機轉(zhuǎn)子繞阻過壓。小型風(fēng)力發(fā)電和大中小型汽輪發(fā)電機組均裝有過壓保護，大小型汽輪發(fā)電機組一般不設(shè)過壓保護。

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.

為了更好地保證所有發(fā)電機乃至全部發(fā)電站的沒問題的平穩(wěn)運行，應(yīng)根據(jù)發(fā)電機的實際情況進行相關(guān)的維修保養(yǎng)，這樣才能讓發(fā)電機維修順利且質(zhì)量高，還能延長其使用壽命，您有什么需求就來我們網(wǎng)站http://www.a7716.cn進行咨詢了解吧！

In order to better ensure the smooth and stable operation of all generators and even all power stations, relevant maintenance should be carried out according to the actual situation of the generator, so that the generator can be repaired smoothly and with high quality, and its service life can be extended.
