SU10303A1 - Electric current limiter - Google Patents

Description

The present invention is intended to open an electrical circuit when a current in it occurs that exceeds a certain voltage by using two electromagnets connected in parallel between themselves and in series with the current receiver.

In FIG. 1 schematically shows the view of the proposed current limiter from the rear; FIG. 2-side; FIG. 3 - in front.

The electromagnets 1, 6 are connected in parallel with each other and in series with the current source, wherein the winding of the electromagnet 6 communicates directly with the electrical circuit and the electromagnet 1 through its pin 2 and rotary contact 3, which is fixed on its axis eccentrically. The distance between the core 2 and the core of the electromagnet 1 is adjusted by means of a special slot in the base of the latter. When the current rises above and beyond which the device is adjusted, the electromagnet 1 must not have its own measles 2 and open the current circuit, as a result of which the current in the circuit connected in parallel, the electromagnet b, which also

There is no measles. The latter, at the same time, will lift one shoulder of the pivoting lever 9 (Fig. 3), fitted at the end of the other arm with a tooth holding the latch 15 of the contact spring of the lever 8. When lifting one shoulder of the lever 9 ,. its tooth will go down, release the latch 15 and the lever 8 will move away, open the current consumption circuit in contacts 12 and 13. To return the lever 8 to its original position and thereby turn on the current, a push button 14 is provided. When operating at high current strengths between bark 2 and Pin 3 turns on the spark-arresting resistance.

The subject of the patent.

1. An electric current limiter characterized by the use of two electromagnet 1, 6 connected in parallel with each other and in series with a receiver of electrical energy, of which electromagnets electromagnet 1 is connected through its pin 2 and through a rotary contact 3 in contact with the latter, eccentrically fixed on its axis, and supplied

a device that regulates the distance of the core 2 from the core of the electromagnet 1, and the electromagnet 6 is connected directly to the circuit and is assigned to open the current consumption circuit using its core 7 and the rotary lever 9 supplied with a tooth holding

the latch 15 of the contact spring lever 8, for returning which to the initial position serves the push button.

2. With the limiter described in Section 1, the inclusion is between the fire 2 and the contact 3 of the arresting resistance.
