Overload Protection TRIAC Relays YS-3F New Energy Products Standard
TRIAC Relays Description:
The relay is an electrical control device, which can give a specified input quantity and keep it for a long enough time so that the controlled quantity will undergo a predetermined step change in the electrical output circuit. When the input volume drops to a certain level and maintains for a long enough time, it returns to the initial state.
TRIAC Relays Features:
1. Speed: It means that the protection device should be able to cut off the short-circuit fault as soon as possible. Its purpose is to improve system stability, reduce the damage of faulty equipment and lines, reduce the scope of faults, improve the effect of automatic reclosing and backup power supply or automatic input of backup equipment, etc.;
2. Sensitivity: When a metallic short circuit occurs within the protected range of equipment or lines, the protection device should have the necessary sensitivity coefficient. Guaranteed to be removed if there is a fault;
3. Selectivity: It means that the protection of the faulty equipment or the line itself should remove the fault first, and only when the protection of the faulty equipment or the line itself or the circuit breaker refuses to operate, the fault can be removed by the protection of the adjacent equipment, the line or the protection of the circuit breaker failure.
