A blocking lightning protection circuit and a blocking lightning protection module using the same

Abstract

The utility model belongs to the lightning protection technical field, concretely relates to a kind of lightning protection circuit of blocking and the lightning protection module of blocking using the circuit, lightning protection circuit, including the main circuit for transmitting signal or electric energy, the input end, transient current blocker, ground circuit, output end are sequentially in the transmission direction on the main circuit, ESD protector is set on ground circuit.Lightning protection module, including shell, the input contact piece, transient current blocker, ground circuit, output contact piece are sequentially connected in the shell, ESD protector is set on ground circuit.In lightning protection circuit, high-speed transient current blocker is connected to ESD protector after ground, lightning protection circuit can quickly produce discharge current, reach the response current of high-speed transient current blocker, make high-speed transient current blocker fast action, guarantee the effectiveness and timeliness of lightning protection.The circuit parasitic capacitance of the lightning protection circuit whole is small, and the universality is higher.Using the lightning protection circuit, the miniaturization of lightning protection product can be realized.
