Abstract
Static isolator for the DC supply circuit of a load (MO) in the event of a surge, consisting of a dipole intended to be inserted into the power circuit of the load and comprising means for detecting a surge (R1, R2, T3, CI), means for filtering and storing the supply voltage (C, R1), means for cutting off the supply to the load (T3, R2, R8, R9, T4, T1, R7, R4), means for detecting the disappearance of the supply voltage (C, R1, R3, R6, T6) and means for erasing the storage means (R2, R6, T3, T6).
Claims4
A static isolator for the DC supply circuit of a load (MO) in the event of a surge, consisting of a dipole (SS) intended to be inserted into the power circuit of the load, this dipole consisting of discrete components and comprising means for detecting a non-fleeting surge (R1, R2, T3, CI), means for filtering and storing the supply voltage (C, R1) which are intended to suppress the effect of a fleeting surge upon the energizing of the load and for retaining in memory the presence of the supply voltage and means for cutting off the supply to the load (T3, R2, R8, R9, T4, T1, R7, R4) which are controlled by the means for detecting a surge, wherein the components of the dipole furthermore constitute means for detecting the disappearance of the supply voltage (C, R1, R3, R6, T6) and means for erasing the storage means (R2, R6, T3, T6).
