Abstract

Embodiments of the present disclosure provide an electrical device, a method for controlling a solid state circuit breaker electrical device, and a computer-readable storage medium. The method comprises: in a closed state of a mechanical switch of the electrical device, closing one of a plurality of electronic switches of the electrical device within a predetermined time period before a zero-crossing point of an input voltage of a bus circuit to which the electrical device is connected; acquiring a current value or a voltage value of a sampling resistor in the electrical device within the predetermined time period; and in response to determining that the current value or the voltage value as acquired is less than or equal to a predetermined threshold, causing an indication component to indicate that there is no short circuit fault in the bus circuit. In this way, it is possible to effectively avoid repeated closing of electronic switches of the electrical device such as a solid state circuit breaker, thereby significantly extending the service life of electronic switches of the electrical device and thereby improving the service life and user experience of the electrical device.
