Traffic Loop Detector Coil

Traffic Loop detector coil with more popular in the parking system. Features: The zero-sequence current transformer magnetic core for leakage protector is made of Fe-based nanocrystalline soft magnetic alloy (1K107). It is used for high sensitivity leakage (touch) protection for household and industrial use according to different technical requirements. And so on. The performance characteristics of the leakage protection switch core made of iron-based nanocrystalline alloy: 1, low coercive force, high initial permeability - can reduce the operating current of the leakage switch 2, the saturation magnetic induction is higher than that of permalloy - Conducive to the selection of higher working magnetic induction point 3, high magnetic permeability - greatly improve the accuracy of the transformer, reduce the ratio difference 4, lightweight, low cost - the price is significantly lower than the permalloy 5, has a good anti-overload Ability and good temperature stability, can work at -55~130 °C for a long time.

Traffic Loop Detector Coil

Introduction of the principle of traffic loop detector coil using the transformer: In the case that the protected circuit works normally without leakage or electric shock., according to some example. The sum of the current through the primary side is equal to zero, that is, the secondary side does not generate the induced electromotive force and the leakage occurs. The protector does not operate and the system maintains normal power supply. When the protected protected circuit is leaking or someone is getting an electric shock, the leakage current is generated due to the presence of the leakage current, and the phasor sum of the currents of the respective phases on the primary side is no longer equal to zero. The alternating magnetic flux appears in the iron core. Under the action of the alternating magnetic flux, the secondary side coil has an induced electromotive force. The leakage signal is processed and compared through the intermediate link. When the predetermined value is reached, the main switch is made. The separation trip coil is energized, the main switch is automatically tripped, and the fault circuit is cut off o achieve protection. loop sensor coil/loop detector coil/traffic loop coil.

The conditions that the leakage protector should meet: It is very important to correctly and reasonably select the rated leakage current of the leakage protector. On the one hand, when the electric shock or leakage current exceeds the allowable value, the leakage protector can selectively act; on the other hand, the leakage The protector should not act under the normal leakage current to prevent unnecessary power loss caused by power interruption.

(1) In order to ensure personal safety, the rated leakage current should not exceed the safe current value of the human body. The internationally recognized 30mA is the safe current value of the human body;

(2) In order to ensure the reliable operation of the power grid, the rated leakage current should escape the low voltage grid. Normal leakage current. In the future, the requirements for energy-saving, environmental protection, high-efficiency and pollution-free development of electric power and electronic products are becoming more and more stringent. Magnetic core components play a very important role in such products, and amorphous nanocrystalline soft magnetic materials It is the best choice to replace traditional magnetic materials by virtue of its excellent magnetic properties. The traffic loop detector coil used well.
