Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of generator sets, in particular to a generator set load simulation system. Background Art
[0002] Generator sets are general-purpose power generation equipment, widely used in military, aerospace, communications, transportation, construction and other industries. They are usually used as independent power stations, mainly to provide power for fixed power equipment and facilities in areas far away from the national power grid. They can also be used as power supply for mobile power equipment such as locomotives, ships, and national defense. With the increase of the use time of the generator set, as well as improper operation, maintenance quality and the influence of the natural environment, various mechanisms, assemblies and systems lose all or part of their specified functions due to wear, aging, cracking, loosening, poor contact, short circuit and open circuit, resulting in various faults in the generator set. Because fault maintenance is a repair activity carried out to maintain, restore and improve the good technical performance of the generator set, detection equipment is required.
[0003] At present, after the repair and maintenance of the generator set, it is necessary to test the technical performance of the generator set to check the quality of the repair and maintenance. However, due to the lack of dedicated simulated load equipment, when the generator set is repaired, it will be directly connected to the power-consuming equipment to test the repair status of the generator set. If it is directly connected to the power-consuming equipment, the actual power may not meet the standard due to the inadequate repair and maintenance of the generator set, causing damage to the power-consuming equipment.

[0005] Preferably, the load heat dissipation unit is four groups of cooling fan axial flow fans, which have low power consumption, fast heat dissipation and low noise. A metal protective mesh cover is arranged on the outer side of the cooling fan axial flow fan.
[0006] Preferably, the monitoring control unit includes a detector, an air switch, a fuse, an indicator light and a push button switch.
[0007] Preferably, the main load installation includes a U-shaped fin dry-burning heat sink, the U-shaped fin dry-burning fin adopts a thickened steel pipe, and the surface of the U-shaped fin dry-burning heat sink is provided with magnesium powder.
[0008] Preferably, the auxiliary load is composed of a plurality of groups of floodlights.
[0009] Beneficial effect: Compared with the prior art, the utility model is a generator set load simulation system. Since the utility model adds a monitoring control unit, a main and auxiliary load unit, and a heat dissipation unit, the design is convenient for observing data changes and for adding and subtracting load changes. The utility model solves the actual maintenance problem, avoids the direct connection of electrical equipment to the generator set, and avoids the economic losses caused by damage to the electrical equipment due to instability, thereby improving the practicality and value of the utility model.
