讲解:来不及修理瓦斯发电机组的危害
众所周知,为了延长发电机组的寿命,需要及时修复发电机组的故障。但是,有些用户认为某些小故障不会影响设备的使用,因此在设备出现故障之前将其忽略,这是非常错误的。本文,瓦斯发电机组小编正在谈论着来不及修理发电机组的危害。
As we all know, in order to prolong the life of generator set, it is necessary to repair the fault of generator set in time. However, some users think that some minor failures will not affect the use of the equipment, so it is very wrong to ignore them before the equipment fails. In this article, the gas generator unit editor is talking about the harm of not having time to repair the generator unit.
1、如果发电机组修理不及时,定子绕组的匝数会短路,短路电压会产生电路电流,这可能会使匝间短路发展为单相接地短路和相间短路。如果定子线圈多相短路,会给单元带来很大的危害,短路电流会导致单元烧损。
1. If the generator set is not repaired in time, the turns of the stator winding will be short circuited, and the short circuit voltage will generate circuit current, which may cause the turn to turn short circuit to develop into single-phase grounding short circuit and phase to phase short circuit. If the stator coil is polyphase short circuited, it will bring great harm to the unit, and the short circuit current will lead to unit burning.
2、发电机组若不立即修复,励磁电流会急剧下降或消失,发电机从系统中吸收大量的无功功率,发电机从同步运行转化开始异步运行,系统电压下降,系统崩溃。
2. If the generator set is not repaired immediately, the excitation current will drop sharply or disappear, the generator will absorb a lot of reactive power from the system, the generator will start asynchronous operation from synchronous operation, the system voltage will drop, and the system will collapse.
3、如果发电机组不立即修理,励磁电路接地。发电机励磁电路:1点接地和2点接地有2种接地。一般来说,励磁电路稍微接地时,对发电机没有严重危害。但是,如果发电机修理不及时,2点接地,转子的磁通、平衡被破坏,引起发电机的强烈振动,终有可能烧坏转子线圈。
3. If the generator set is not repaired immediately, the excitation circuit is grounded. Generator excitation circuit: there are two kinds of grounding for 1-point grounding and 2-point grounding. Generally speaking, when the excitation circuit is slightly grounded, there is no serious harm to the generator. However, if the generator is not repaired in time and the two points are grounded, the magnetic flux and balance of the rotor will be damaged, causing strong vibration of the generator, which may eventually burn out the rotor coil.
4、如果发电机组不立即修理,机组将变为过电压。发电机在运行中突然失去负载时,如果发电机不能立即恢复,由于调速系统的较大惯性会产生过电压,发电机组的绝缘层可能被破坏。
4. If the generator set is not repaired immediately, the generator set will become overvoltage. When the generator suddenly loses load during operation, if the generator cannot be recovered immediately, overvoltage will be generated due to the large inertia of the speed governing system, and the insulation layer of the generator set may be damaged.
5、如果发电机组来不及的话,机组将超负荷。发电机过载,意味着发电机的运转超过了额定容量。如果发电机不立即修理,短时间的过负荷运转会使发电机定子线圈的温度上升,绝缘部分的劣化会加速,发电机的寿命会缩短。如果长时间过载,发电机定子线圈烧坏,终发电机可能无法发电。
5. If the generator set is too late, the unit will be overloaded. Generator overload means that the generator operates beyond the rated capacity. If the generator is not repaired immediately, the temperature of generator stator coil will rise due to short-term overload operation, the deterioration of insulation will accelerate, and the life of generator will be shortened. If the overload lasts for a long time and the generator stator coil is burnt, the final generator may not be able to generate electricity.
6、发电机组如果不立即修理,定子会通过过电流。定子的过电流通常是由外部短路或系统振荡引起的。如果发电机不及时修理,发电机的定子温度会稍微上升,绕组绝缘部分的老化会加速严重的情况下,可能会引起其他的错误。为了防止上述故障的发生,用户在发现故障后立即停止机械,不管故障大小,在投入使用前须修理设备。此外,柴油发电单元具备相应的保护装置,能够更好地保护单元。
6. If the generator set is not repaired immediately, the stator will pass over current. Overcurrent of stator is usually caused by external short circuit or system oscillation. If the generator is not repaired in time, the stator temperature of the generator will rise slightly, and the aging of the winding insulation will accelerate seriously, which may cause other errors. In order to prevent the occurrence of the above faults, the user shall stop the machine immediately after finding the fault, regardless of the size of the fault, and must repair the equipment before putting it into use. In addition, the diesel power generation unit is equipped with corresponding protective devices, which can better protect the unit.
