Above-mentioned surge immunity experimental system, wherein, said conductive metal sheet is aluminium sheet or copper coin.
The beneficial effect of the utility model is: the utility model can be done the surge immunity experiment to a tested device, thereby accurately estimates the antisurge interference performance of this tested device.Simultaneously, the utility model is simple and be easy to realize.
Description of drawings
Fig. 1 is the system schematic of the surge immunity experimental system of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
See also Fig. 1; The surge immunity experimental system of the utility model; Comprise insulation table 1, be tiled in conductive metal sheet 2 on the desktop of this insulation table 1, surging signal generator 4, coupling/decoupling network 5 and the tested device 6 of insulcrete 3, connection successively, wherein:
The thickness of insulcrete 3 is 0.1 meter, places the desktop of insulation table 1;
Surging signal generator 4 and coupling/decoupling network 5 all place the desktop of insulation table 1;
Tested device 6 places on the insulcrete 3, and the length of the signal cable between this tested device 6 and the coupling/decoupling network 5 is less than 2 meters.
In the present embodiment, conductive metal sheet 2 is aluminium sheet or copper coin.
The utility model can simulate respectively on the power lead with communication line on surge test.Because the impedance of circuit is different, the waveform of surge on these two kinds of circuits is also different, simulate respectively.In the present embodiment, the surging signal generator 4 that is used for the experiment of analog power line can produce the voltage wave of 1.2/50us and the current wave of 8/20us, and the open circuit output voltage is 0.5kV-4kV; Short-circuit output current is 0.25kA-2kA; Internal resistance 2 Ω, per minute once divide positive-negative polarity each 5 times; What be used for signal cable is the 10/700us voltage waveform, open circuit output voltage 0.5kV-4kV, and dynamically internal resistance 40 Ω divide positive-negative polarity.The test grade is as shown in table 1:
Table 1
The harsh grade that experiment will apply depends on the condition that equipment uses:
1 grade: the better protect environment, surge voltage is no more than 500V, like the pulpit in factory or the power station.
2 grades: the protection environment is poorer slightly than 1 grade, and surge voltage is no more than 1kV, as does not have strongly disturbing factory.
3 grades: general electromagnetic disturbance environment, no special mounting requirement, the surge amplitude is no more than 2kV, like the cable system of common installation, payable workplace and electric substation etc.
4 grades: receive the environment of serious harassing and wrecking, surge voltage can reach 4kV, like civilian pole line, does not add the high voltage substation of protection etc.
Above embodiment only supplies to explain the usefulness of the utility model; But not to the restriction of the utility model; The technician in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also make various conversion or modification; Therefore all technical schemes that are equal to also should belong to the category of the utility model, should be limited each claim.
