Polarization relay

Polarization relay refers to the relay operated by the combined action of polarization magnetic field and control current through the magnetic field generated by the control coil . Its polarized magnetic field is generally generated by magnetic steel or DC polarized coil ; The suction direction of relay armature depends on the direction of current flowing in the control winding . In automatic device 、 Remote control and telemetry devices and communication equipment can be used as pulse generation 、 DC and AC conversion 、 Sum up 、 Differential, signal amplification and other circuit components . It has the outstanding advantages of high sensitivity and fast action speed .

Principle of polarization relay
　　 Because the principle of polarization relay is to make the polarization magnetic field and current interact , Therefore, in the process of adjustment, the orientation of the armature on the magnetic pole can be changed , It can also change the spacing between the metal surface of the armature and the permanent plane , Maybe you can also move the porcelain frame to adjust the current , However, in order to ensure the normal operation of the polarization relay, we need to be very careful in the process of adjustment . Finally, it is necessary to change the direction of dynamic and electric shock to change the return current . In principle, to adjust the polarization relay is to adjust the variable elements to change the process of acquisition .
