Over-current protection relay

smartpower-freeshock-proof

Franklin invented a lightning arrester! Taiwanese Leon Hsu invented a power-free cutout!! 1. Smart Power-Free Shockproof Overcurrent Trip (POCT) Introduction: An autonomous shockproof cutout~ Short-circuit accident nemesis~ Japan Fukushima Daiichi nuclear power plant accident: The big east Japan earthquake that occurred on March 11, 2011 caused a series of equipment damage. When the 275 kV tower of the first nuclear power plant fell, the circuit breaker could not perform power isolation, thus destroying the entire power distribution system. It led to chain disasters, such as cooling system failure, furnace core melting and radioactive material leakage. POCT (Needless of the control or signal power) smart cutout, can accurately detect the fault current and trigger the tripping circuit breaker within 0.02 seconds (from the occurrence of overcurrent to the activation of the circuit breaker), effectively suspend the expansion of the short circuit. POCT features: 1. Power- Free & Shockproof. 2. Trip the circuit breaker easily, quickly and safely 3. Light and easy to be installed 2. POCT function 1. Mechanical driving force: (1) The initial force is greater than 1.0 N (2) Driving force: 200~500 N (default 300 Newton) (3) Stroke 0.5cm 2. Signal transmission (activating the circuit breaker) time: within 0.02 seconds (Faster than 0.025~0.033 seconds(60~) of the world IEEE Std C37.09-2018 ) (1) Signal transmission time: within 0.01 seconds (2) System startup time: within 0.01 seconds
