Adjustment and test of hydro-generator under no-load excitation regulator

The mediation and practice of the excitation actuator under no-load of the hydro-generator. At the rated speed of the generator, the excitation is in the manual position. The start-up inspection is to check the manual operation unit's transfer line. Must not be lower than% of the rated excitation voltage of the generator.

Check the voltage adjustment boundary of the excitation transfer system, which should meet the design conditions. The automatic excitation regulator should be able to perform stable and smooth transfer within the% ~% boundary of the generator's no-load rated voltage.

Measure the open loop magnification of the excitation actuator. Record and observe the characteristics of the excitation actuator. Regarding the thyristor excitation system, you should also check the current and voltage coefficient of the power rectifier bridge under the condition of rated no-load excitation current. Should not be lower than ...

In the no-load form of the generator, the stability and overshoot of the excitation actuator pouring, manual and automatic switching, channel switching, start and stop with the exciting actuator are separately checked. When the generator is under no-load and the speed is in the range of% ~ %, Within the rated value boundary.

    Blue smoke, fire reason: It means that the engine is burning oil. There are three types of reasons: first, the piston ring goes opposite, and the oil comes in the cylinder; the second is the oil level of the oil pan of the atmosphere filter, which leads the ring. The height of the groove; Third, the gap between the duct and the valve stem is too poor. Expulsion idea: Adjust the piston ring so that the opening teeth of the ring are staggered 120 degrees or 180 degrees, and the opening teeth of the ring should avoid the piston pin hole and the side pressure is poor. Adjust the height of the oil level of the oil filter of the atmosphere filter below the height of the annular groove; if the clearance between the duct and the valve stem is too poor, replace the component and reduce the clearance. The normal mutual assistance clearance between the two is 0.0

    Before starting, you should check whether the fuel volume of the fuel tank is rich, and there is no oil leakage in each oil pipe and the discussion area; whether the cooling system water is rich, clean and leak-free, and whether the fan belt is tight or not. The internal combustion engine and generator drive parts should be connected and trusted. The wires of the input line are well-insulated, complete and effective in all aspects. After starting, it should run at low speed for 3 to 5 minutes. After the temperature and oil pressure wheel are normal, the initial work can be done. The generator should be no different in the speed increase. Ring, the slip ring and commutator are well brushed, no jumping and sparking phenomenon. After the operation is stable and the frequency and voltage reach the rated value, power can be supplied to the outside.

    In the power generation industry in China, we have been working hard, pursuing the concept of quality and service, and for the sake of customers, the full power generator chooses China and your generator is a professional housekeeper. At present, the diesel generator set maintenance market refers to damage inspection and routine maintenance. Two aspects: after maintenance refers to the failure of the diesel generator, there are problems with various accessories, such as replacing the generator or

    The diesel engine is working normally, but the generator fails to generate electricity or the voltage is very low. This may be due to the components associated with the generator, such as: the exciter is damaged, and the excitation voltage cannot be supplied. The excitation current is taken in. The rotor's dead center residual magnetism is weakened or declining. It will make the generator unable to generate electricity or the transmission voltage is extremely low. The right to respond is usually: use an appropriate DC voltage and directly connect to the excitation winding according to the polarity Magnetization. Carefully inspect the exciter and the cyclotron rectifier, find abnormal components or windings, and replace them for restoration. The generator's transmission voltage is unstable, and
