Latest Patents

One of Rongqiang Yao's key inventions is a high sensitivity leakage current detection interrupter (LCDI). This device includes a shielded wire, a current leakage detection unit, and a tripping mechanism. The shielded wire consists of a live core and a neutral core, each wrapped in conductive shell wires. The current leakage detection unit features a pair of rectifying diodes connected in series between the live and neutral lines of a power supply, along with a voltage dropping resistor, thyristors, and resistor-capacitor (RC) voltage dropping filter circuits. The tripping mechanism is designed with control units that are activated by the thyristors. When either thyristor is turned on, the corresponding control unit activates the tripping mechanism, effectively switching off the power supply.
