Specific embodiment
Referring to Fig.1, Fig. 2, a kind of surge impact simulator, including power circuit 1, master controller 3 and surge circuit 4,
The power circuit 1 one terminates alternating current input, and the other end connects master controller 3, and master controller 3 connects surge circuit 4, the wave
Gush that circuit 4 includes master switch KA and circuit occurs for surge parallel with one another, it includes opening of being serially connected that circuit, which occurs, for the surge
After closing K1 ... KN and capacitor C1 ... CN and the switch KL1 ... KLN and inductance L1 ... LN, the master switch KA that are serially connected and parallel connection
Surge circuit occur be connected in series between the firewire of alternating current input and the zero curve of alternating current input, circuit occurs for the surge
Both ends are parallel with discharge circuit.
Detected electric appliance need to can be just powered by simulator, and the electricity that alternating current inputs is become main control by power circuit 1
Electricity needed for device 3, master controller 3 control surge circuit 4 surge generation, and the intensity of adjustable surge impact, the time,
Phase；When master switch KA is opened, capacitor C1 ... CN, inductance L1 ... LN momentary charge on circuit occur for surge, generate big electricity
Flow the surge of high voltage；After master switch KA shutdown, surge occurs capacitor C1 ... CN, inductance L1 ... LN on circuit and passes through electric discharge electricity
Road electric discharge, is ready for surge next time.Surge occur circuit switch K1 ... KN and KL1 ... KLN open it is more, surge
Intensity is bigger, therefore the number of surge generation circuit is set as needed, and switchs the number opened and is controlled by master controller 3, wave
The attack time is gushed by the service time and turn-off time of the control of master controller 3 master switch KA to realize；Master controller 3 passes through extension
Regular hour is switched on or off master switch KA again to realize the phase for adjusting surge impact.Master controller 3 is singlechip chip,
It is equipped with memory module in it, records the number of surge impact.It can select individually to turn on the switch K1 according to actual needs ... in KN
It is several or individually open several in KL1 ... KLN, switch K1 ... KN and KL1 ... KLN can also be opened simultaneously.
Filter circuit 5 is equipped between the power circuit 1 and master controller 3.Filter circuit is by the clutter in power circuit 1
It filters out, guarantees normal operation circuit.
The master controller 3 is connected with artificial set interface 6.Display interface and setting are provided in artificial set interface 6
