Description

(54) DEVICE FOR SCRAPTURE

one

This invention relates to electrical engineering; in particular, to magnetization devices.

The closest to the proposed technical entity is a device for magnetization, including a DC source, a charging capacitor, a discharge thyristor with a control circuit, a magnetizing coil, and a stopper. an electromagnet with a control circuit on the basis of a switching thyristor, with the charging capacitor connected in parallel with the DC source, parallel to the charging capacitor connected in series after the properly connected discharge thyria-1 torus and magnetized & kushka 1Q.

The disadvantage of this device is that regardless of the serviceability of the pulsed magnetizing cat-proz-20, the electromagnet is turned on and the magnetizing product is reset from the device. Such a principle of operation of the device requires additional1 monitoring of products for magnetization, which reduces the functionality of the device.

The purpose of the invention is to expand the functionality of the device.

Claims (1)

The goal is achieved by the fact that the device for magnetizing the device includes a direct current source, a charge capacitor, a discharge thyristor with a control circuit, a magnetizing coil, a stopper electromagnet with a control circuit based on a switching thyristor, and the charge capacitor is connected parallel to the source post connected in parallel to the charging capacitor are connected in series a discharge thyristor and a magnetizing clamp, equipped with a threshold element and an additional coil oh, magnetically coupled to the magnetizing coil and connected at one end to the magnetizing coil and the other through a threshold element to the control input of the switching thyristor of the lock electromagnet. The drawing shows a magnetization device. The device contains a source of direct current t (rectifying bridge diodes), a thyristor 2 for charging capacitors, a photoresistor 3 for turning on the thyristor 2, a charging capacitor 4, a capacitor 5 for delaying the release of the electromagnet 6, which simultaneously serves to turn on the discharge thyristor 7 through Zener diode 8, pulsed magnetizing coil 9, commutation thyristor 10, diode II, resistor 12, additional coil 13, magnetically coupled to pulsed magnetizing coil 9, and threshold element 14, for example, a dynistor. The device works as follows. The magnet freely sliding along the inclined chute darkens the photoresistor 3, the voltage drop on which is applied to the control electrode of the thyristor, the latter opens and starts charging the capacitors 4 and 5. When the capacitor 4 charges up to the power supply voltage , the thyristor 2 is closed, and the capacitor 5 through the diode and the resistor 12 will continue to charge from the battery of the capacitor 4 to the voltage of the zener diode 8. When switched on by the flasher 8, the thyristor 7 opens and the pulse discharge of the capacitor 4 occurs through pulsed magnetizing coil 9. The charge time of the capacitor is chosen such that after switching on the thyristor 2 the magnetized magnet can reach the stop fixing this magnet in the center of the magnetizing coil 9. When the current passing through the magnetizing coil 9 decreases, a coil 13 decreases in the coil 13, the coil 9 decreases, and the current passing through the magnetizing coil 9 in the coil 13 decreases, which through the threshold element 14 is supplied to the thyristor Yu, including it, which leads to the operation of the electromagnet 6, which controls the stop, fixing the permanent magnet in the center of the magnetizing catupzhi 9. The capacitor 5 beats p sivaeg electromagnet 6 in the ON state until rex long as a permanent magnet will not pass through a packed in a special groove abutment. The diode 11 serves to eliminate the discharge of the capacitor 5 to the pulsed magnetizing coil 9. By virtue of the fact that the control electrode of the switching thyristor 10 of the electromagnet b through the threshold element 14 is connected to the output coil of an additional coil 13 which is magnetically coupled to the magnetized coil 9, the electromagnet 6 can be switched on only when the magnetizing coil 9 is working properly (if there are no interwave loops or open circuits), i.e., when the permanent magnet is magnetized. The advantage of the proposed device is the elimination of the possibility of passage through it of non-magnetized buildings.
