Abstract
The utility model relates to a surge protector, in particular to a low-residual-voltage surge protector, which belongs to the technical field of electricity. The low-residual-voltage surge protector comprises a primary bleeder circuit and a secondary bleeder circuit; wherein the primary bleeder circuit is connected with an input end, the secondary bleeder circuit is connected with an output end, the primary bleeder circuit and the secondary bleeder circuit are connected through an inductor and are grounded through a gaseous discharge tube. The low-residual-voltage surge protector has the advantages that the circuits are simpler, and the variety of the elements is reduced; The material and the space are saved, and the residual voltage Ures of the improved circuits is lower.
Description
Technical field
The utility model relates to technical field of electricity, particularly surge protector.
Background technology
Along with progress of science and technology, the volume of various electronic equipments, device is more and more littler, and power consumption is also more and more lower.But thing followed problem be this kind equipment and device the overvoltage tolerance more and more a little less than, use surge protector (SPD) can effectively protect them.
Surge protector has the difference of a port (parallel connection) and two ports (series connection), and the overvoltage protection element has votage limit type, switching mode and combined.
In the surge protector of prior art, the one-level leadage circuit respectively carries the different gas of parameter with the secondary leadage circuit and puts pipe, and its weak point is that residual voltage Ures value is than higher, and because the relation of element kind and quantity causes the product overall volume bigger.
The utility model content
Technical problem to be solved in the utility model is, a kind of low residual voltage surge protector is provided, and than prior art, has littler volume and lower residual voltage Ures value.
The technical scheme that the utility model solve the technical problem employing is; low residual voltage surge protector; comprise one-level leadage circuit and secondary leadage circuit; the one-level leadage circuit connects input; the secondary leadage circuit connects output; connect by inductance between one-level leadage circuit and the secondary leadage circuit, it is characterized in that, described one-level leadage circuit and secondary leadage circuit are put pipe ground connection by gas jointly.
The beneficial effects of the utility model are, circuit succinctly more, components and parts use kind to reduce.The parameter that ordinary circumstance, the gas in the traditional circuit are put pipe V1, V2 is different, and the pressure sensitive voltage of RV1 and RV2 is also different; The pressure sensitive voltage of piezo-resistance RV1 of the present utility model and RV2 can be identical.Under the same impulse current of regulation,, improve the piezo-resistance of circuit use and lack than the piezo-resistance that traditional circuit uses if residual voltage Ures value is identical; And the inductance value of decoupler L1 also can reduce much saving material and space.In other words, if the quantity or the decoupler of piezo-resistance are identical, the residual voltage Ures of improved circuit is lower.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
