Who is the inventor of the world's first generator?

Introduction Who is the inventor of the world's first generator? The world's first generator dates back to 1832. Frenchman Bixy invented the hand-cranked DC generator. Its principle is to rotate a permanent magnet.

Who is the inventor of the world's first generator?

The world's first generator was invented by the Frenchman Bixy in 1832. The manual DC generator was based on the principle of changing the magnetic flux by rotating the permanent magnet to generate an induced electromotive force in the coil. , and produces this electromotive force in the form of direct voltage.

A generator refers to a mechanical device that converts other forms of energy into electrical energy. It is driven by water turbine, steam turbine, diesel engine or other electric machines to convert the energy generated by water flow, air. flow, fuel combustion or atomic nuclear fission. Mechanical energy is transmitted to the generator, which is then converted into electrical energy.

Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. There are many forms ofe generators, but their operating principles are all based on the law of electromagnetic induction and the law of electromagnetic force.

< p>The development history of generators:

In 1866, Siemens of Germany invented the self-excited DC generator;

In 1869, Gram of Belgium manufactured an annular armature and invented the annular armature generator. This type of generator uses hydraulic power to turn the generator rotor. After repeated improvements, it reached an output power of 3.2KW in 1847;

In 1882, Gordon of the United States produced a generator with an output power. of 447 kW. A giant two-phase generator with a height of 3 meters and a weight of 22 tons;

In 1896, Tesla's two-phase alternator began operating at the Nyala power station, with 3 750 kW and 5,000 V alternating current. . Sent to Buffalo, 25 miles away.

1. The generator set does not operate according to the specified technical conditions, such as stator voltage. too high, iron loss increases. The load current is too large and the copper loss of the stator winding increases. If the frequency is too low, the speed of the cooling fan will slow down, affecting the heat dissipation of the machine. The power factor is too low, which increases the rotor excitation current and causes the rotor to heat up. Check whether the indication of the monitoring instrument is normal. If this is abnormal, the necessary adjustments and treatments must be carried out to operate the engine according to the specified technical conditions.

2. Inlet air temperature is too high or inlet water temperature is too hightoo high and the cooler is blocked. The inlet air or water temperature must be lowered to eliminate blockage in the cooler. Before the fault is cleared, the motor load must be limited to reduce the motor temperature.

3. Bearing wear. If wear is not significant, the bearing may be partially overheated. If the wear is significant, it can cause friction between the stator and the rotor, causing the stator and rotor avoidance parts to overheat. Bearings should be checked for noise. If friction between the stator and rotor is detected, the machine should be stopped immediately for maintenance or replacement of the bearings.

4. The insulation of the stator core is damaged, causing a short circuit between parts, leading to an increase in local eddy current losses in the core. Heating can damage the stator winding in thes serious cases. The machine must be stopped immediately for maintenance.
