Problems solved by technology
[0003] If each frame has a preset rated current, then in the product management process, the rated current under different frames can only be identified through the external code, and the rated current marked on the external code is often a range value, and cannot be accurate to the system Rated current under each frame of the solid state circuit breaker
This often leads to unmanageable and complex applications of solid state circuit breakers

The embodiment of the invention discloses a current detection method, system and device, a solid-state circuit breaker and a readable storage medium, applied to a current detection system and used for detecting the rated current of the solid-state circuit breaker, the current detection system comprises a processor, an AD sampler and a sampling resistor, the sampling resistor is arranged at a power supply connecting end of an analog-digital conversion module of the solid-state circuit breaker, the sampling resistor accesses a voltage signal through the protective resistor, the AD sampler is electrically connected with the sampling resistor, the processor is in communication connection with the AD sampler, and the current detection method comprises the following steps: acquiring a sampling value at the sampling resistor of the solid-state circuit breaker; searching a sampling interval to which the sampling value belongs in a preset sampling value-current value relation list; and determining the rated current of the solid-state circuit breaker according to a preset sampling value-current value relation list and the sampling interval. Through the preset sampling value-current value relation list, all rated current parameters in the systematic solid-state circuit breaker can be obtained only through one resistor.
Description
technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a current detection method, system, device, solid-state circuit breaker and readable storage medium. Background technique [0002] Serialized solid-state circuit breakers have multiple rated currents of different specifications. Generally, a frame of a solid-state circuit breaker is downwardly compatible with rated currents of multiple specifications. For example, an 80A frame is downwardly compatible with 63A, 50A, 40A, 32A, 25A, 16A, 10A, 6A, one frame corresponding to the rated current of multiple specifications will cause the following problems: [0003] If each frame has a preset rated current, then in the product management process, the rated current under different frames can only be identified through the external code, and the rated current marked on the external code is often a range value, and cannot be accurate to the system The rated current under each ...
