Introduction And Characteristics Of High Power Resistor Load Bank

Introduction of high power resistor load bank:

With the development of China's economy, the load capacity of electrical equipment is increasing, and the capacity of generator set as backup power supply is also increasing. It needs multiple high-power diesel generators to be connected to the grid. Considering the loss and construction problems in the process of high-capacity power transmission, and in order to meet the needs of high-voltage electrical equipment, the use of high-voltage generator set has become a better choice for users.

The output voltage of the high-voltage generator set is 10kV, which is consistent with the voltage of the original power supply system, and can be directly connected to the power supply system, eliminating the equipment investment of power supply and distribution systems such as high current cables. At the same time, under the condition of the same power, due to the high output voltage and small output current of the unit, the power loss in the power transmission process is the smallest, which is suitable for long-distance transmission. Especially in the application occasions with large load requirements and long power transmission distance, high-voltage diesel generator set has obvious advantages of large capacity and long-distance power supply, strong reliability and low cost of supporting distribution system. Therefore, high-voltage diesel generator set has been widely used in industries and mines, communication operators, data centers, ports, metallurgy, airports and other fields.

High voltage generator set has certain advantages, but compared with low-voltage diesel generator set, high-voltage generator set itself is not a small investment. Compared with domestic and foreign high-pressure diesel generator sets, domestic high-pressure diesel generator has obvious price advantages and can meet the needs of most domestic enterprises in technology. Therefore, considering the cost, more and more enterprises choose to purchase domestic high-pressure diesel generator sets. Although domestic high-pressure diesel generator sets continue to make breakthroughs in technology, there is still a certain gap with foreign diesel generator sets. Some key parts are easy to be damaged when the whole machine is not well maintained, affecting the use at critical times and increasing maintenance costs. Therefore, attention should be paid to the on load test and maintenance of the engine.

High power intelligent load bank can accurately detect the output power and load carrying capacity of high-voltage generator set. It is composed of measurement and control components and high-voltage load bank. It can be used with computer to realize intellectualization, automatically complete the special test of all electrical parameters of generator set, and generate charts, curves and test reports at the same time, so as to provide scientific detection means and basis for high-power generator set equipment.
