Description

In the proposed polarized relay

as an element of the magnetic circuit, a closed ferromagnetic toroid,

. which is influenced by the control current creating in it the corresponding

the magnetic flux, closed only in the toroid, makes the conductor bad for the common magnetic flux, which is supposed to achieve a change in the magnetic flux in the working part of the relay. In the indicated relay, shown schematically in the drawing, along the path of the main constant flow passing through the bark 3, the toroid 2 is turned on, equipped with a winding 5. In the absence of current in the Middle Cory 3, the toroid is attracted. When passing through the current winding controlling the relay, the iron of the toroid core becomes saturated, as a result of which the resistance of the magnetic circuit of the permanent magnet 1 increases. Last thing

entails a decrease in the main magnetic flux reel. In this case, spring 4 can overcome the weakened attraction of the core to the toroid and tear it off from the latter, thereby driving the relay.

The subject of the patent.

A polarized relay, characterized in that a magnetic circuit of a permanent magnet 1 passing through the pin 3 of it is connected to a toron 2 which can be pulled by the pin 3 which is provided with a winding through which the control relay passes a current to , in order to saturate the iron core of the toroid, increase the resistance of the magnetic circuit of the permanent magnet and thereby cause a weakening of the mattatic attraction of the core to the toroid and pulling away the core from it by the spring 4.
