7 kilowatt generator voltage is small, 5 5 kilowatt generator can use 7 kilowatt regulator

7 Reasons for the low voltage of the kilowatt generator.

1. The remanence voltage is too low (less than 2% of the rated voltage at the rated speed) can not be excited--- can be magnetized with 3-6 volt thousand batteries or batteries and other DC charging, and the positive pole should be connected to L4 and the negative pole to L2 when magnetizing.

2. The wiring error --- checked in detail, and the connection is correct according to the wiring diagram 3. The magnetic field coil is broken--- reconnect the broken circuit, and solder it firmly with solder, and wrap it with external insulation.

4. If the terminals of the excitation device are loose or in poor contact--- wipe the terminals clean and connect them properly.

5. If the contact between the brush and the collector ring is poor or the brush pressure is not enough--- clean the surface of the collector ring, grind the surface of the brush to make it consistent with the surface of the collector ring, and replace the constant pressure spring on the brush.

6. The meter is not allowed to --- calibrate the meter regularly.

7. The magnetic field coil is partially short-circuited or grounded--- and the magnetic field coil is replaced.

8. When the armature coil of the generator is broken--- find out where the broken circuit is, and re-weld and wrap.

9. Generator armature coil short circuit--- short circuit will cause serious heating phenomenon, should be disassembled and replaced.

10. If the silicon rectifier is damaged or the resistance and capacitance of the silicon element is damaged by overvoltage protection--- the rectifier and the resistance and capacitance protection parts are replaced.

11. After overhaul, the air gap of the reactor is too small--- increase the air gap.

The voltage is small and the speed is increased, mainly between the frequency reaches. You can collect it on the request: Sichuan··· Huapai··· Electricity··· Try it.

A kilowatt generator can use a 7 kilowatt regulator. However, it is recommended that you choose the right regulator according to the rated power of the generator when choosing a stable voltage shield. If the regulator is too low, it can cause the pin to overload the generator or not work properly, while if the regulator is too power, it can waste resources or add unnecessary costs.

Therefore, when selecting a voltage regulator, it is necessary to select it according to the actual needs and equipment parameters to ensure the normal operation and service life of the equipment.

Summary. Hello dear <>

A kilowatt generator can't use a 7 kilowatt regulator, and if you use a 7 kilowatt regulator to control a kilowatt generator, it may cause the following problems:1The regulator is not working properly:

If the power of the regulator is too high, it may cause the regulator to not function properly or to regulate the generator. 2.Damaged generator:

Using an oversized regulator may cause excessive load on the generator, which can damage the generator's circuitry and components.

Can a kilowatt generator use a 7 kilowatt regulator.

Hello dear <>

If you use a 7 kilowatt regulator to control a kilowatt generator, it may cause the following problems:1The regulator is not working properly:

If the power of the regulator is too high, the regulator may not function properly or the generator cannot be regulated and buried controlled. 2.Damaged generator:

The use of an oversized regulator may cause excessive load on the generator, which can damage the generator's circuitry and components.

The voltage regulator plays the role of stabilizing the output voltage. The voltage regulator has constant voltage regulation. voltage, control circuit, and servo motor.

When the input voltage or load changes, the control circuit sampling, compares, amplifies and lifts the Huai, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage regulator, and automatically adjusts the ratio of the coil turns, so as to maintain the stability of the output voltage. The original power regulator stabilized the voltage by the runout of the relay. When the grid voltage fluctuates, the automatic correction circuit of the power regulator is activated, so that the internal relay acts.

Forcing the output voltage to be kept near the set value, this circuit has the advantage of simple circuit, but the disadvantage is that the voltage regulation accuracy is not high, and every time the relay jumps and shifts, it will cause an instantaneous interruption of the power supply and spark interference. I wish you a happy life and a happy chain grinding pro! Hope mine is helpful to you.

Hello dear, what is the reason why the 8 kilowatt generator only emits 170v voltage? 1. The transformer capacity is too small, and the load exceeds the transformer capacity too much, resulting in too low voltage; What is the cause of the low voltage? The cross-sectional area of the wire is too small, the load exceeds the rated electric Laling current of the wire, and the voltage is too low due to high temperature.

The wire is too long, the cross-sectional area is not enough, and the voltage loss is too low.

Summary. Reasons and treatment methods for lower and lower generator voltage: 1. Reasons:

The speed of the generator prime mover is too low. Treatment: Adjust the speed of the generator prime mover to the rated value.

2. Reason: Some of the rectifier diodes in the generator are broken down. Processing:

Inspect and replace the broken diode. 3. Reason: The contact surface of the brush is too small, the pressure is insufficient, and the contact is poor.

Treatment: If it is caused by the surface of the commutator, the surface of the commutator can be polished with an abrasive cloth at low speed, or the spring pressure can be adjusted. 4. Reason:

There is a short circuit or ground fault in the stator winding or the excitation winding. Treatment: Check for faults and clear them.

The reasons for the lower and lower voltage of the generator and the treatment method: 1. The reason: the speed of the generator prime mover is too low.

Treatment: Adjust the speed of the generator prime mover to the rated value. 2. Reason:

The generator has a partial rectifier diode that is broken down. Treatment: Inspect and replace the broken down diode.

3. Reason: The contact surface of the brush soldering liquid is too small, the pressure is insufficient, and the contact is poor. Processing:

If it is caused by the surface of the commutator, the surface of the commutator can be polished with an abrasive cloth at low speed, or the spring pressure can be adjusted. 4. Reason: There is a short circuit or grounding fault in the stator winding or the excitation winding of the matching wheel.

Treatment: Check for faults and clear them.

5. The reason is that the exciter brush is not in the neutral position, or the spring pressure is too small. Treatment: Adjust the brushes to the correct position with a barn, replace the brushes, and adjust the spring pressure.

6. Reason: The resistance of the excitation circuit is too large. Processing:

Reducing the resistance of the magnetic field rheostat to increase the excitation current is nonsense. For semiconductor excitation generators, check whether the additional winding joints are broken or the stove is connected incorrectly.

Hello, Lu Yan inquired for you that the working current of the kilowatt motor is not ampere, and the working current of the kilowatt motor depends on the rated power factor (and power supply voltage) of the motor. The rated current of a motor can be calculated by the following formula: rated current (i) = rated power (p) v * pf) Therefore, the rated current of a kilowatt motor will be:

i = 7500 v * pf) if v = 220 v, pf = then i = 7500 (220 * = so, the kilowatt motor working current is not ampere, but amp oh pro. <>

The motor working current of a kilowatt is not necessarily ampere. The magnitude of the motor working current depends on factors such as voltage, power factor, and rated power of the motor. Generally speaking, the higher the rated power of the motor, the greater the working current.

For a kilowatt motor, if it has a rated voltage of 380 volts and an operating efficiency of yes, then it has a rated current of about amps, not amps. The specific values also need to be calculated according to the specific parameters of the motor. It should be noted that when the motor is working, the current will also be affected by the load change, so in practical applications, it is necessary to select the appropriate motor according to the load of the motor to ensure the safe and reliable operation of the motor collapse.

Hello Kiss is happy to answer this question for you. Is a 24 kW generator overloaded with a kW motor? 1. As long as the prime mover can be dragged, the generator is absolutely fine.

2. According to 75% of the effective work of electrical appliances, a 24 kilowatt generator can completely drive an 11 kilowatt motor "Generators refer to mechanical equipment that converts other forms of energy into electrical energy, which is driven by water turbines, steam turbines, diesel engines or other power machinery, converting the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transferring it to the generator, and then converted into electrical energy by the generator. Generators have a wide range of uses in industrial and agricultural production, national defense, science and technology, and daily life. There are many forms of generators, but their working principles are based on the laws of electromagnetic induction and electromagnetic force.

Therefore, the general principle of its construction is to use appropriate magnetic and conductive materials to form magnetic circuits and circuits that carry out electromagnetic induction with each other, so as to generate electromagnetic power and achieve the purpose of energy conversion.
