發(fā)電機(jī)應(yīng)配備哪些維護(hù)措施
發(fā)電機(jī)維護(hù)保養(yǎng)與其他詳盡負(fù)載維護(hù)保養(yǎng)各不相同。由于發(fā)電機(jī)的勵(lì)磁電和電流量與一般機(jī)械設(shè)備高壓開(kāi)關(guān)柜的交流電流和工作標(biāo)準(zhǔn)電壓距離十分大,我們?cè)诰S護(hù)機(jī)器設(shè)備方面也有很大的區(qū)別。下面焦化發(fā)電機(jī)組廠家為您講講發(fā)電機(jī)應(yīng)配備哪些維護(hù)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(hù):電機(jī)轉(zhuǎn)子繞阻及其小組出線雙色過(guò)電流保護(hù)。
1. Longitudinal differential maintenance: motor rotor winding resistance and its group outgoing line two-color overcurrent protection.
2、打橫差動(dòng)保護(hù):電機(jī)轉(zhuǎn)子繞阻單相匝間過(guò)電流保護(hù)。僅有當(dāng)單相電機(jī)轉(zhuǎn)子繞阻有兩個(gè)或好多個(gè)并接環(huán)城路造成2個(gè)或三個(gè)中性點(diǎn)輸電線時(shí),才可以拼裝這類維護(hù)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(lì)和去磁維護(hù)保養(yǎng):為了防止機(jī)發(fā)電機(jī)在低勵(lì)(勵(lì)磁電低于數(shù)據(jù)格式穩(wěn)定限定相符合的勵(lì)磁電)或去磁(勵(lì)磁電為零)后從系統(tǒng)吸收消化許多功率因數(shù)角,對(duì)系統(tǒng)導(dǎo)致欠佳傷害,容量為100MW及以上的發(fā)電機(jī)均配備該維護(hù)機(jī)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(guò)壓保護(hù):用于發(fā)電機(jī)長(zhǎng)久性超額定負(fù)荷運(yùn)行時(shí)的數(shù)據(jù)信號(hào)維護(hù)保養(yǎng)。中小型發(fā)電機(jī)僅設(shè)置過(guò)負(fù)荷維護(hù)保養(yǎng);機(jī)發(fā)電機(jī)應(yīng)分別配備電機(jī)轉(zhuǎn)子過(guò)壓保護(hù)和勵(lì)磁電流繞阻過(guò)壓保護(hù)。
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(jī)轉(zhuǎn)子繞阻過(guò)電流量維護(hù):當(dāng)發(fā)電機(jī)縱向差動(dòng)保護(hù)范圍外造成短路故障問(wèn)題,短路故障電子器件或高壓隔離開(kāi)關(guān)的維護(hù)保養(yǎng)拒動(dòng)時(shí),該維護(hù)作為外部短路故障問(wèn)題的貯備,也作為縱向差動(dòng)保護(hù)的貯備維護(hù)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(jī)轉(zhuǎn)子繞阻過(guò)壓保護(hù):用于防止所有負(fù)載突然缺失而產(chǎn)生的電機(jī)轉(zhuǎn)子繞阻過(guò)壓。小型風(fēng)力發(fā)電和大中小型汽輪發(fā)電機(jī)組均裝有過(guò)壓保護(hù),大小型汽輪發(fā)電機(jī)組一般不設(shè)過(guò)壓保護(hù)。
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.
