Zicai generator

1. Product overview of brushless HXW generators

       The HXW series brushless generators (divided into land and marine) have insulation grades including B, E, F, and H. The generator specifications range from 3-1000KW and are equipped with a universal transition interface. They can match various prime movers and can adapt to various usage conditions and harsh environments. The product has been well received by users for its reliable performance and reasonable price.

2. Faults in brushless HXW generator products
       1. There is no indication for the voltmeter
   (1) The generator does not generate electricity and is treated as item 2
   (2) The voltmeter circuit is not open and check the wiring and fuse, and replace it with a new product
   (3) The voltmeter is damaged and replace it with a new product

2. Power cannot be generated
   (1) Wiring errors are checked and corrected according to the line
   (2) The excitation winding of the main generator or exciter is connected incorrectly, resulting in an incorrect polarity; the polarity of the excitation current of the exciter machine does not match the polarity of the permanent magnet often occurs after replacing the excitation winding due to wiring errors.
   (3) The silicon rectifier element breaks down short circuit, and the forward and reverse directions are conducted by a universal multimeter to check the forward and reverse resistance of the rectifier element, and replace the damaged component.

3. The no-load voltage is too bottom (for example: the line voltage is only 100V)
   (1) The excitation winding of the excitation machine is broken, replace the disconnected coil or connect the coil circuit
   (2) The excitation winding of the main generator is severely short-circuited. The excitation winding of the excitation machine is very high. The excitation winding of the main generator has severe heat, the vibration increases, the DC resistance of the excitation winding is much smaller than the normal value, replace the short-circuit coil
   (3) At the rated speed of the automatic voltage regulator, measure whether the output DC current value of the automatic voltage regulator is equal to the factory no-load characteristics of the motor, check the automatic voltage regulator

4. Excitation principle of brushless HXW generator.
       Brushless excitation is to install the main circuit of excitation rectification on the generator rotor shaft, that is, to install an AC exciter on the shaft. The DC excitation winding of this alternator is fixed. The AC armature winding, rectifier and the host excitation winding form a coaxial rotor whole. The external supply of excitation current to the AC exciter. The electricity emitted by the AC exciter is rectified by the rotary rectifier and then supplied to the host excitation winding. In this way, the host voltage can be changed by controlling the excitation current of the exciter.
