Short Circuit Protection TRIAC Relays YS-3F Household Appliances Small
TRIAC Relays Description:
The relay is an electric control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
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.
