Abstract: An over-temperature protection method and apparatus, a device and a storage medium for a solid-state circuit breaker are provided. A time constant indicative of an association between a temperature rise amount and an operating time of a solid-state circuit breaker operating at a predetermined operating current is determined. A first temperature rise amount of the solid-state circuit breaker is determined based on a temperature rise amount detected before the solid-state circuit breaker is turned off, a duration for which the solid-state circuit breaker is turned off, and the time constant. A second temperature rise amount of the solid-state circuit breaker is determined based on the first temperature rise amount, the time constant, and an operating current detected after the solid-state circuit breaker is turned on. A turn-on state of the solid-state circuit breaker based on a comparison between the second temperature rise amount and a predetermined threshold is controlled.

Abstract: Embodiments of the disclosure provides a current sampling apparatus based on a two-wire circuit and a device. The current sampling apparatus comprises a sampling circuit arranged between a high voltage side and a low voltage side of a line to which the current sampling apparatus is connected; a sampling resistor connected in series in the sampling circuit to form a sampling current under a potential difference between the high voltage side and the low voltage side; a compensation circuit arranged close to the sampling resistor and adapted to provide a compensation current to generate a compensation magnetic field during flow of the sampling current in the sampling circuit, and the compensation magnetic field being adapted to at least partially offset an induced magnetic field of the sampling circuit; and a pair of voltage sampling interfaces respectively arranged at the two ends of the sampling resistor.
