Abstract
The utility model relates to a power source lightning-protection module, which is formed by that a gas discharge tube is connected in series with a varistor, wherein, the varistor, which is welded at one end of the gas discharge tube, can safely prevent electric equipment from damages by lightning. The utility model has the advantages of simple structure and low cost.
Description
The utility model relates to a kind of electronic product, particularly a kind of power lightning protection module.
Existing power lightning protection product structure is more complicated all, and cost is higher, also has single employing piezo-resistance or single employing gas discharge tube to be used for power lightning protection.If single employing piezo-resistance lightning protection residual voltage can be too high,, can cause residual voltage low excessively if adopt the gas discharge tube lightning protection.
It is a kind of simple in structure that the purpose of this utility model is to provide, the power lightning protection module that cost is low.
The utility model is realized by following technical scheme: it is composed in series by gas discharge tube and piezo-resistance, and piezo-resistance is weldingly fixed on gas discharge tube one end, and two respectively picks out a lead-in wire.Also can respectively weld a piezo-resistance, and on piezo-resistance and gas discharge tube, respectively pick out a lead-in wire by one three utmost point gas discharge tube two.
The utility model power lightning protection module, the low excessively shortcoming of residual voltage that the too high and single employing gas discharge tube of residual voltage that has overcome single employing piezo-resistance and brought causes, only need the utility model is attempted by power inleting terminal, can be so that system have increased effective lightning protection function.And the utlity model has the low characteristics of cost simple in structure.It can be widely used on the lightning protection device of various power-supply devices.
Accompanying drawing 1 is used for the structural representation of single phase poaer supply for the utility model.
Accompanying drawing 2 is used for the structural representation of two-phase power supply for the utility model.
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.A specific embodiment of the present utility model such as accompanying drawing 1 provide.It is adopt always flow as voltage be 360 volts piezo-resistance 1 with mobile always be that 230 volts gas discharge tube 2 is connected into a single-phase lightning-protection module as voltage.Piezo-resistance 1 is welded on the gas discharge tube 2, respectively picks out a lead-in wire 3 from piezo-resistance 1 and gas discharge tube 2.When it and in the power line end of incoming cables, when in case momentary pulse voltage appears in thunderbolt, it moves immediately, and immediately this pulse voltage is shorted to the earth in nanosecond in the time and releases, and restriction mould both end voltage is about 360 volts of direct currents, voltage falls to pressing about 140 volts, thereby makes equipment avoid descending to cause for a long time damage at high pressure conditions.And when having served as loss of voltage, the module recovery high-impedance state, thus the device power supply (DPS) operate as normal do not influenced.
