The foundation of this system provides a good reference to promote the standardization and intelligence of the overhaul and maintenance of vacuum switches. This paper develops a special HF pulse power supply for internal pressure estimation, which achieves the output of HF-HV sinusoidal pulse wave whose frequency and amplitude can be modified respectively, and meets the design requirements according to the results of Simulink simulation and practical experiments. With the help of AT89S52, this paper designs an I~2C serial bus based signal detection system for peak value signal acquisition of HF pulse currents, which communicates with the upper computer by asynchronous serial communication for uploading the data. In the upper computer, a human computer interface is developed by Matlab software, whose functions are to do some computation and graphic display, such as calibrating the relation curve of vacuum degree and peak value of HF pulse currents, vacuum degree computation, and vacuum lifetime evaluation analysis basing on grey forecasting model as well as making relative suggestions.

The time-domain response of the induced currents on a scattering object irradiated by a plane wave with a Gaussian pulse in time is expanded as an associate Hermite series in this paper. Using the isomorphism of the associate Hermite function and its Fourier transform, the frequency-domain information can be obtained similarly to the time-domain expansion. According to the corresponding relation between time-domain analysis and frequency-domain analysis, and using the early-time response and the low-frequency information of the induced currents, the non-known coefficients in the expansion series can be decided. The entire responses of the induced currents on the scattering object in both time and frequency domains can be obtained at one time by simultaneous extrapolation computation using both the early-time response and the low-frequency information of the induced currents.

These Thoughts so oppress'd my Mind, that I began to give over my Enterprize, and having haled my Boat into a little Creek on the Shore, I stept out, and sat me down upon a little rising bit of Ground, very pensive and anxious, between Fear and Desire about my Voyage; when as I was musing, I could perceive that the Tide was turn'd, and the Flood come on, upon which my going was for so many Hours impracticable; upon this presently it occurr'd to me, that I should go up to the highest Piece of Ground I could find, and observe, if I could, how the Sets of the Tide, or Currents lay, when the Flood came in, that I might judge whether if I was driven one way out, I might not expect to be driven another way home, with the same Rapidness of the Currents: This Thought was no sooner in my Head, but I cast my Eye upon a little Hill, which sufficiently over-look'd the Sea both ways, and from whence I had a clear view of the Currents, or Sets of the Tide, and which way I was to guide my self in my Return; here I found, that as the Current of the Ebb set out close by the South Point of the Island; so the Current of the Flood set in close by the Shore of the North Side, and that I had nothing to do but to keep to the North of the Island in my Return, and I should do well enough.
