Latest Patents

Zijian Xu holds a patent for an over-energy protection circuit, a residual current device, an electronic device, and a power distribution box. This invention features a protection circuit with high operating reliability. It includes a first over-energy absorption circuit, a second over-energy absorption circuit, and a residual current determining circuit. The first over-energy absorption circuit receives a first electrical signal output from a current transformer. When the voltage value of the first electrical signal is greater than or equal to a first preset threshold, it performs step-down processing on the first electrical signal to obtain a second electrical signal. This second electrical signal is then output to the second over-energy absorption circuit. Alternatively, if the voltage value of the first electrical signal is less than the first preset threshold, the first electrical signal is directly output to the second over-energy absorption circuit.
