Common reasons and solutions for generator failure to produce electricity:
1. Cause: Wiring error.
Treatment: Check and correct according to the wiring diagram.
2. Reason: The speed is too low.
Processing: Measure the rotation speed and keep it at the nominal value.
3. Cause: There is mud or oxide on the wiring joint between the stator winding and the generator power distribution equipment, the wiring screws are loose, the connection wire is broken and the stator winding is broken.
Treatment: Use a multimeter or light test method to find out where the disconnection is. Check the connection and contact of each wiring screw.
4. Cause: The field circuit is disconnected or has poor contact.
Treatment: Use a multimeter to find out where the broken wire is, re-solder the broken wire firmly and wrap it for isoler.
Detailed information1: Under normal circumstances, due to the influence of high-order harmonics or manufacturing processes, the air gap under each magnetic pole is uneven and the magnetic potential is uneven , which results in very low voltage. If the voltage is between one and several volts, it is not dangerous and there is no need to handle it.
2: The generator winding has a short circuit or poor insulation to the ground, which causes the performance of the electrical equipment and generator to deteriorate and easily generate heat. It must be repaired in time to avoid expansion. the accident.
3: There is no voltage between the neutral line and ground when there is no load, but voltage appears when there is a load. This is due to the imbalance of the three phases. the load must be adjusted to make it fundamentally balanced.
The current of ggenerator is too large
1: The load is too high, the load must be reduced.
2: If a phase short circuit or ground fault occurs in the transmission line, the line should be inspected and restored to normal after the fault is cleared.
What is the problem when the gasoline generator does not produce electricity?
Repair methods for gasoline generators not producing electricity are as follows:
1. Check and correct wiring errors according to the circuit diagram.
2. The windings are poorly connected, resulting in incorrect polarity. This needs to be checked and corrected. The rotating silicon rectifier element is short-circuited and conducts in both the forward and reverse direction. and reverse resistance of the rectifier element and replace it if damaged.
3. The excitation winding of the main generator est disconnected. Use a digital multimeter to check and measure the main generator excitation winding. The resistance is infinite and must be connected to the excitation line.
4. The windings of the small and medium-sized automobile gasoline generator or exciter of the main engine are severely short-circuited, and there is usually significant overheating. A short circuit of the excitation winding can be judged by the resistance of its main and tributary currents. Damaged windings must be replaced.
Tips
Use a digital multimeter to check the voltage range. Turn the digital multimeter knob to the DC voltage range of 30 V. Connect the red test lead to the synchronous motor terminal. the generator set and the black test lead to the chassis. Let the engine run at medium speed, the voltage standard of 12V electrical system should be around 14V andThe voltage standard of 24V electrical system should be around 28V. If the measured voltage is the battery voltage, it means that the generator set is not producing electricity.
Why do gasoline generators use oil? Is the door too high and cannot be adjusted?
How to check if the generator is gasoline doesn't produce electricity?
1. First check whether the engine oil and gasoline are newly added. Otherwise, they have been added for more than three months and the engine oil and gasoline need to be replaced. Since engine oil and gasoline are only valid for three months, oil and gasoline used for more than three months have lost their viscosity and have no effect.
2. Check if the gasoline generator oil and gasoline are full. Otherwise, the generator will not be able to turn on and start.
3. If the machine has not been used for a long time,the carburetor oil level will drop, corrosion will occur inside, and the oil hole will be blocked. All you need to do is clean the carburetor. .
4. If the above conditions are met, check whether the spark plug ignites. Otherwise, remove the spark plug and put gasoline on it before reinstalling it to see if the generator fires. does not produce sparks, replace the spark plug with a new one.
5. Check if the voltage regulator is broken. If it is broken, replace it with a new one.
6. Check the circuit to see if any part of the circuit has fallen out or has poor contact. If so, treat it immediately.
7. If there are no problems after the above inspections, the engine is burned out and needs to be replaced with a new one.
You can handle it yourself, loosen the rocker nut and use pliersto connect the pivot rod to the housing. commande speed Pay. pay attention to your left side. If that doesn't work, go right. If this doesn't work, you have a problem with the throttle tension spring. It is not properly installed on the carburetor. >or the spring is broken. I don't know what it is, if the engine can't get down to high revs, if you have to add more engine oil, you may have put too much, just add some. .
Generators refer to mechanical equipment that converts other forms of energy into electrical energy. It is driven by water turbine, steam turbine, diesel engine or other electric machines, and burns water flow and air. flow and fuel. Or the energy generated by nuclear fission is converted into mechanical energy and transmitted to the generator, which is then converted into electrical energy.
Generators are widely used in productionn industrial and agricultural, national defense, science and technology and daily life. There are many forms of generators, but their operating principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: using suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction among themselves to generate electromagnetic energy and achieve the conversion goal of energy.
Generators are generally composed of stators, rotors, end covers, bearings and other components.
The stator consists of the stator core, wire windings, machine base and other structural parts that secure these parts.
The rotor is composed of a winding of the rotor core (or a magnetic pole, a magnetic yoke), a retaining ring, a center ring, a slip ring, a fan and a rotating shaft.
The stator and rotor of the generator are connected and assembled by bearings and end covers, so that the rotorIt can rotate in the stator and carry out the cutting movement of the magnetic lines of force, thereby generating an induced electrical potential, which is extracted through the terminal block and connected to the circuit to generate a current.
