But the present invention is not limited thereto, can also effectively find the generation of surge by the monitoring to electric current, no matter for
Which, is all one of optional scheme of the invention.
Relating to how to realize the calculating of surge energy, the present invention provides several feasible according to different types of detection data
Solution:
In an optional embodiment of the invention, use temperature for detection data, in the step S20, by following
The surge energy of each secondary surge is calculated in formula:
Wherein, Δ T characterizes temperature rise, the surge energy of Δ U characterization injection SPD unit, the corresponding thermal capacitance of Cm-SPD unit

For the clearly above content, expansion elaboration is carried out to the derivation process of formula above below:
SPD is one and the related relatively independent therrmodynamic system of installation environment.
According to the first law of thermodynamics:
Δ Q=Δ U+ Δ A ... ... ... ... ... ... ... (1)
In formula: the variable quantity of energy in Δ U-system；
Δ Q-outside enters the heat of system；
The function that Δ A-system external portion is done；
When the energy value (Δ U) for entering this system is positive value (energy is just flowing into), can increase in system, temperature will
It can be increased with Q value.Conversely, the interior of system can drop when the energy value (Δ U) for entering this system is negative value (energy outflow)

Temperature rise can establish by above formula and inject the respective function of the energy of protector:
In use, SPD system is by forms such as electromagnetic field radiation, mechanically deform, acousto-optics to external work (Δ
A), scale factor or additional normal can be used in the energy variation proportion very little of this part in the calculating of engineer application
Ripe form is characterized in function.
Such as:
Or:
In formula: k-is used to characterize the scale factor of protector system external portion acting factor
In a lightning surge events, into the energy of SPD system:
Δ U=u*i*t
It can be deformed into:
In formula: both end voltage when u-SPD absorbs impact electric current, due to its nonlinear characteristic, can with its maximum value (
It is known as residual voltage in IEC standard) Ures replacement.The maximum value of Ures numerical value and dash current i have fixed corresponding relationship.
T1-impact initial time
T2-impact terminates the time
It is derived by formula (3), (4):
In formula: m-coefficient of colligation,
So far, we have obtained to be characterized the formula (5) of temperature rise with dash current, in determining protector system,
All coefficient of colligation m be it is metastable, formula calculate result can satisfy the requirement on engineer application.

Look for the surge energy for determining the SPD unit secondary surge；The mapping table is to test to obtain in advance for such SPD unit
Or the design parameter theoretical calculation according to such SPD unit obtains.
Likewise, not using lookup table mode, but table is changing into the figure of fitting, in optinal plan, in the step
In S30, under each environment temperature section by such SPD unit pre-established, surge energy and electric current, voltage, temperature, resistance
The matched curve relationship of anti-or capacitance variable quantity compares the surge energy for determining the SPD unit secondary surge；The fitting
Curved line relation is to test the design parameter theoretical calculation obtained or according to such SPD unit in advance for such SPD unit to obtain.
After being realised that is surge energy, the naturally available several modes of those skilled in the art establish its electricity
The variable quantity of parameter, environmental parameter etc. and the corresponding relationship of surge energy in turn, know so that surge energy be calculated
Surge energy, counter can also push away the variation of these parameters.
In the preferred embodiment of the invention, in the step S30, according to the statistic that surge energy has occurred and
Working time, determine the depletion rate of energy, so the design parameter in conjunction with the SPD unit, working environment parameter and its
With the relationship for the energy summation that can bear during entire work, reckoning obtains the remaining life of the SPD unit.
It should be noted that according to the result of study that a large amount of test data obtains show SPD working life and its
The summation for the surge energy born during entire work is closely related.The integral of the Current versus time of this surge energy surge
It indicates (might not so be calculated), unit A.s, also referred to as the ampere-second resource of protector.Research shows that for same
The SPD of type, have ampere-second resource relatively, therefore manufacturer can confirm this of protector in process
Parameter, i.e., " energy summation that the SPD unit can bear during entirely working " mentioned above are can to manufacture it in SPD
It just obtains, limited trials is still either passed through by theoretical calculation, do not probe into range in of the invention.

Gush current system by when generate ampere-second consumption and steady-state power conditions under by when generate ampere-second consumption can be with different
Conversion factor is added in the calculating for reducing ampere-second resource, i.e., mentioned above to calculate its surge energy with different coefficient accumulations
Statistic, certainly, for specific calculation, which may also be 0.So in clearly current depletion rate and remaining
It is remaining consume resource in the case where, the remaining service life can be calculated naturally, certainly, can also introduce other it is specific because
Element, establishes increasingly complex mathematical model, but no matter its model why, without departure from present invention basic ideas mentioned above.

Tlifespan=f (UN, ID, T, t, Δ E)
Wherein, TlifespanFor life expectancy；
UNFor the pressure sensitive voltage of varistor；
IDFor the leakage current of varistor；
T is the temperature parameter during protector works, the accumulated amount of maximum value and temperature including temperature；
T is protector cumulative operation time；
The energy parameter that bears during Δ E is protector work, including current peak Imax, quantity of electric charge maximum value Qmax,
Surge energy Δ U, consumption power frequency supply energy and their accumulated amount.
In optional embodiment of the present invention, among the step S30, before or after, further include determining this time electricity
The gradient and amplitude for the temperature rise gushed, and then in the step S40, the surge of different gradients and amplitude is accumulated with different coefficients
Calculate the statistic of surge energy.Why is specific coefficient, can be according to the micro-judgment of those skilled in the art or by limited
Secondary experiment gropes to obtain.
It further include detecting the SPD unit and environment temperature in optional embodiment of the present invention, when its temperature difference is greater than in advance
If boundary when, then judge remaining life be less than particular value.It is to be understood that when operating temperature increases, it will accelerate
Ampere-second resource consumption speed.When temperature be more than some boundary, even if without additional surge current, ampere-second resource can also consume rapidly
Totally.So the present invention utilizes the boundary, as the judgement of another dimension, when the temperature difference is greater than the boundary, it is believed that ampere-second
Resource can rapidly deplete, it is also assumed that the SPD unit is in catastrophe failure, should not use, so, optinal plan of the present invention will
Its service life is less than particular value, and this boundary can be obtained completely by limited trials or theoretical calculation.
