Technical Characteristics of Dingbo Series High Voltage Diesel Generator

There are many classification methods for diesel generator sets. According to the level of engine speed, it can be divided into high, medium and low speed generators. According to the size of power, it can be divided into large, medium and small generator sets. According to the output voltage and frequency of the generator, it can be divided into AC power generation. For generator sets and DC generator sets, when the voltage frequency is 50Hz, the rated voltage of small and medium generators is generally 400V (three-phase) or 230V (single-phase), and the rated voltage of large generators generally is 6.3~10.5kV.

The composition and technical characteristics of Dingbo Power series high-voltage diesel generators:

1. The high-voltage generator consists of main generator (with damping winding), exciter, permanent magnet machine and excitation device system.

2. The winding of the high-voltage generator is made of special imine film wrapping with high hydrolysis resistance or flat copper wire wrapped by double-layer mica. , the slot is fully filled, the insulation integrity is high, and it has high mechanical strength, high shock resistance and good insulation strength; the insulation grade of the stator part of the generator is F grade, and the rotor part adopts the H grade insulation grade. The insulating material used has the characteristics of no moisture absorption, high dielectric strength and low dielectric loss, and can withstand severe temperature changes.

3. The excitation system of the high-voltage generator adopts the excitation control system based on the microprocessor-based digital automatic voltage regulator of Basler in the United States or ABB in Switzerland; this type of regulator uses PWM modulation to provide excitation current to the exciter stator, it is more suitable for parallel control operation with other generators or grid systems. The excitation system using the analog automatic voltage regulator can also be configured according to the needs of the user.

4. Standard permanent magnet machine (PMG). It can not be affected by any load changes or load properties, and can stably provide power to the automatic voltage regulator, ensure the stability of the output voltage of the high-voltage generator, and meet any occasions with high requirements on voltage and waveform.

5. The machine base is made of steel plate welded and annealed. The two ends have a four-width structure, and the middle is an octahedral structure.

6. The protection level of the high-voltage generator is or, which can meet the user's use in various environments.

7. A temperature sensor is installed in the stator winding of the high-voltage generator to protect the generator. The bearings at both ends are equipped with temperature measuring elements for monitoring the operating temperature of the bearing. If the user has special requirements, an air filter can be installed to meet the requirements of using diesel generating set in an environment with sand and dust. Anti-condensation heaters can be installed on special requirements.

8. The bearing structure is double bearing. The front end adopts two sets of bearings, and the rear end adopts a set of bearing structure, which has the characteristics of small vibration, low noise and stable operation.

9. The cooling method is equipped with fan self-cooling structure as standard, and air-air cooling and air-water cooling structure can be adopted according to user requirements.

Dingbo series high-voltage generator sets have the advantages of large capacity, long-distance power supply, high voltage regulation accuracy, reasonable structure of supporting power distribution system, superior dynamic performance, small voltage waveform distortion, high voltage and low current characteristics, high efficiency, and long service life. At the same time, it has excellent grid connection function. Its voltage is generally 6300V, 10500V, 11000V. It has good performance and high reliability in any environment, and is widely used in large capacity and long distance power transmission. Applications, such as industrial and mining, metallurgy, data centers, ports, airports and other fields.
