Description

Technical Field

[0001] This application relates to the technical field of electrical component testing, and in particular to a simulated load resistor. Background Technology

[0002] Water-cooled resistors are braking resistors that dissipate energy through water cooling. They are mainly used in the electric braking systems of heavy equipment such as ship propellers, oil drilling rigs, and cranes, covering a power range from kilowatts to megawatts. They employ a water-electricity separation cooling design, utilizing the cooling efficiency of water to achieve heat transfer, and feature excellent heat transfer performance.

[0003] In the process of producing and designing water-cooled resistors, it is necessary to test the effectiveness of the water-cooling system. Currently, when testing the water-cooling system of water-cooled resistors, the resistor core is usually installed directly in the water-cooling system for testing. Regarding the above-mentioned related technologies, the inventors have found that this not only consumes the state of other components of the water-cooled resistor, but also requires the resistor core to be redesigned and manufactured for different water-cooling systems, which increases the workload and losses, and also reduces production efficiency.
