Problems solved by technology

Changes in water temperature can change the resistance value of water, which in turn leads to changes in the power of the water resistance. This change will cause the output power of the internal combustion generator to drift. Therefore, the water resistance is an unstable dynamometer device, which is not conducive to internal combustion generators. performance measurement of

[0005] 2. In order to stabilize the water temperature of the water resistance, it is generally necessary to increase the cooling device and the water circulation system to keep the water temperature stable. Therefore, the method of using the water resistance dynamometer will result in an increase in equipment investment and an increase in the area occupied by the factory.

[0006] 3. The electrodes loaded with water resistance are generally made of steel plates, and the manufacturing cost of coating non-insulating anti-corrosion materials on the plates is relatively high; when the plates are immersed in water for discharge, the galvanic corrosion will accelerate the corrosion and oxidation of the plate surface, When the oxide layer falls off, it will cause short-circuit faults on adjacent plates, which is not conducive to safe production.

[0007] 4. Dry-type resistors will generate a lot of heat when consuming the electric energy of the internal combustion generator set, and a cooling fan is required to take away the heat generated by forced ventilation, so that there will be a large amount of high-temperature air around the dry-type resistors, which will cause high-temperature hazards to the dry-type resistors , and also cause damage to the surrounding greenery, so it is inconvenient to use the dry resistance load

[0008] 5. During the working process of the dry resistance load, the operation of the cooling fan will blow leaves, insects, sand, rain and snow and other debris onto the dry resistance. The leaves and insects can cause fire, and the sand, rain and snow can cause resistance. Short circuit, there is a potential safety hazard;

[0009] 6. The adjustable resistance load will consume all the electric energy generated by the internal combustion generator set, resulting in great waste
