Abstract
Increase in the protection safety against electrical load 2. Essence A device comprises a rectifier 5, actuating element 4, in series switched in the power-supply line 3 and a control block, which responds both to overvoltage and to reduce of the voltage of the value power-supply line in respect to the preset level. The actuating element presents an electrical switch, to the power input of which are connected in series switched unit 1 for the protection against shorting and impulse filter 2. The control block comprises adjustable threshold units of high 6 and low 7 levels, connected thereto comparators 8 and9, a unit 10 of reference voltage, logical circuit “AND”, units of delay 11 and 13. In case of overvoltage the device breaks out loading during the half-cycle of power-supply frequency. During the reduce of the voltage in respect to the preset level, the break of the load takes place as well. 3. Field of Application Electrical technique.
