Brushless HXW Generator

1. Product Overview

       HXW series brushless generators (divided into land use and marine use), the insulation grades include B class, E class, F class, H class, the generator specifications range from 3-1000KW, and are equipped with a universal transition interface, which can be connected with various It is matched with similar prime movers and can adapt to the needs of various usage conditions and harsh environments. The products are well received by the majority of users for their reliable performance and reasonable price.

2. Product failure

1． Voltmeter has no indication

1. If the generator does not generate electricity, handle it as item 2.

2. If the voltmeter circuit is blocked, check the wiring and fuses and replace them with new ones.

3. The voltmeter is damaged and replaced with a new one.

2. Cannot generate electricity

1. Check and correct wiring errors according to line

2. The excitation winding of the main generator or exciter is connected incorrectly, resulting in incorrect polarity; the excitation current polarity of the exciter does not match the polarity of the permanent magnet, which often occurs after replacing the excitation winding due to incorrect wiring. It should be checked and corrected

3. The silicon rectifier element is broken down and short-circuited, and both forward and reverse conductivity are maintained. Use a multimeter to check the forward and reverse resistance of the rectifier element and replace the damaged element.

3. No-load voltage is too low (for example: line voltage is only 100V)

1. The excitation winding of the exciter is broken. Replace the broken coil or connect the coil circuit.

2. The excitation winding of the main generator is seriously short-circuited and the excitation winding current of the exciter is very large. The excitation winding of the main generator is severely heated, the vibration increases, and the DC resistance of the excitation winding is much smaller than the normal value. Replace the short-circuit coil.

3. When the automatic voltage regulator fails at the rated speed, measure whether the output DC current value of the automatic voltage regulator is equal to the factory no-load characteristic of the motor. Check the automatic voltage regulator.

3. Excitation principle

　　Brushless excitation is to install the main excitation rectifier circuit on the generator rotor shaft, that is, an AC exciter is installed on the shaft. The DC excitation winding of this alternator is fixed, and the AC armature winding, rectifier and main machine excitation winding are together. structure It forms a coaxially rotating rotor as a whole, and provides excitation current to the AC exciter from the outside. The electricity generated by the AC exciter is rectified by the rotating rectifier and then supplied to the excitation winding of the host. In this way, the host voltage can be changed by controlling the excitation current of the exciter.
