Abstract: The present disclosure provides a solid state breaker and a power supply system. The breaker includes: a first port and a second port configured to connect a first external system; a third port and a fourth port configured to connect a second external system; a first electronic switch connected between the first port and the third port; a second electronic switch connected between the second port and the fourth port; and a control unit configured to control the first electronic switch and the second electronic switch to be turned off in a case of detecting an electricity leakage occurs in the second external system. The breaker is provided with electronic switches at both poles, so that it can provide effective protection for the human body by quickly turning off the electronic switches provided at both poles, in a case of an electricity leakage of the prosumer to the ground.

Abstract: A power source automatic transfer device is provided, including: a first and second power source input end; an auxiliary power supply unit whose electric energy is acquired from a first and second power source; a device output end connected to a load; and a power source switchover unit including a control unit and a power source switchover switch, the power source switchover switch including a first and second power source switchover switch, wherein a first input end of the first and second power source switchover switch are respectively connected to the first power source input end and the second power source input end, a second input end of the first and second power source switchover switch are both connected to an output end of the auxiliary power supply unit, and an output end of the first and second power source switchover switch are connected with the device output end.

Abstract: A bistable display includes: an inner box constituted of a first substrate, a second substrate and a box body surrounding a space between the first substrate and the second substrate, a bistable display material is injected into the space, and one or more of a common electrode conductive layer, a pattern conductive layer, and a background conductive layer are respectively formed on the first substrate and/or the second substrate inside the inner box, and the common electrode conductive layer is led out of the inner box through a common electrode, the pattern conductive layer is led out of the inner box through a pattern electrode, and the background conductive layer is led out of the inner box through a background electrode.
