Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention is described in detail.
It is the first embodiment of surging suppression of the present invention and overcurrent protection, the surging suppression of the present embodiment referring to Fig. 2
System and overcurrent protection 100 be used to a power supply 11, the live wire (L) and the neutral conductor (N) electric coupling of such as AC power, with
Receive electric power input, and the neutral conductor with a first input end I1 and being connected with the live wire of power supply 11 and power supply 11 connects
The the second input I2 for connecing, and to one load 12 electric couplings, for should electric power to load 12 one first output end

Surge absorber 20 has a first end 21 and one second end 22, and the first end 21 connects with first input end I1
Connect, second end 22 is connected with the second input I2 and the second output end O2, and in the present embodiment, surge absorber 20 can be with
It is a such as metal oxide piezo-resistance (MOV, Metal Oxide Varistor), its current-voltage characteristic curve has
Height it is non-linear, that is, when the voltage between its two ends no more than one protection magnitude of voltage when, surge absorber 20 can be presented height
Impedance and equivalent to open-circuit condition, and when the voltage between its two ends exceedes the protection magnitude of voltage, surge absorber 20 can wink
Between present Low ESR and equivalent to short-circuit condition.
Thermal Cutoffs 30 has one the 3rd end 31 and one the 4th end 32, and the 3rd end 31 and surge absorber 20 the
One end 21 connects, and the 4th end 32 is connected with the first output end O1, and Thermal Cutoffs 30 is used to sense surge absorber 20
Temperature, for example surge absorber 20 and Thermal Cutoffs 30 are integrated and are packaged together, as single component, or by temperature
Degree fuse 30 is close to or is attached to the surface of surge absorber 20.Or also can be by a heat conductor by surge absorber 20

During the limit value that can be born more than Thermal Cutoffs 30, Thermal Cutoffs 30 will blow, to avoid load 12 from bearing excessive
The impact of electric current and damage.
After being generated heat because surge absorber 20 bears high current, can thus reduce its protective capacities, such as impedance becomes
Low, causing the leakage current at its two ends increases, therefore, the characteristic of its usually high impedance can gradually drop with the increase of number of lightning strokes
Low its impedance so that the leakage current for flowing through surge absorber 20 is increasing, until there is short circuit phenomenon, (for example leakage current increases
Amplitude exceed surge absorber 20 can bear power when), surge absorber 20 will catching fire and lose surging protection
Ability, produces danger, so that the high pressure surging of generation of being struck by lightning cannot effectively be led back to the end of power supply 11 by surge absorber 20, this
