Generally speaking, generators generate alternating current. Generators produce alternating current. If a collector is used, pulsed direct current can be supplied externally. After adding filter equipment, stable direct current can be obtained.
The principle of the generator is the Faraday electromagnetic induction phenomenon. When part of the conductor in a closed circuit moves to cut the magnetic field lines, it generates current. electromagnetic induction. The generated current is called induced current. We see that two conditions must be met to generate an induced current: it must be part of the conductor of a closed circuit it must carry out a movement which cuts the magnetic field lines;Generator usage specifications
(1) The battery ground polarity must be consistent with the alternator ground polarity. The consequenceFailure to meet specifications is that the diode will be damaged due to large current discharge from the diode.
(2) When the six diodes of the rectifier are connected to the stator winding, it is absolutely forbidden to use a megohmmeter or a 220V AC power supply to check the insulation status of the alternator. Otherwise, the diode could easily fail and become damaged.
(3) After the engine stalls, the ignition switch must be turned off. If the flame is not extinguished in time, the battery will continue to discharge, thereby affecting the magnetic field and shortening the battery life.
(4) When the alternator is running, you cannot use the fire test method to check if it is producing electricity. Otherwise, the diode and electronic components may be easily damaged.
1. The three main hosts of thermal power plants refer to boilerseras, steam turbines and generators.
2. Thermal Power Plant:
A thermal power plant, called a thermal power plant, is a plant that uses coal, oil and natural gas as fuel to produce electrical energy. Its basic production process is as follows: Fuel is. The boiler burns and heats water into steam, converting the chemical energy of the fuel into thermal energy. The steam pressure causes the steam turbine to rotate, and the thermal energy is then converted into mechanical energy. the steam turbine drives the rotation of the generator, converting mechanical energy into electrical energy.
