Protection against overvoltages incidents in equipment connected by signal via cable

摘要

"Protector against overvoltages incidents in equipment connected by signal via cable.The utility model relates to an innovative and practical device, which has effectively eliminate the enormous damage to equipment connected into signals via cable.When subjected to overvoltages of any nature. The device is protected by an enclosure from electromagnetic interference from external mechanical actions and bad weather.Its working principle is the dissipation of the energy of the overvoltage by means of specific elements, avoiding that reaches the apparatus.In accordance with the drawing 1 (a) in the annex,This model is composed of a spark gap L1 (protector primary) connected between the signal input of the operator (1) and the grounding of the cable (3), a spark gap L2 (conectad secondary protector)In parallel with the spark gap L1, a capacitor C1 (protector tertiary) 2.2 NF connected in series between the input of the signal of the carrier (1) and the exit of the cable service provider for the user device (2); a decoupling capacitor (C2) 2.2 NF connected between the grounding of the cable (3) and the grounding of the user device (4).
