(3) beneficial effect
Disclosed in the utility model, a kind of high-tension switch cabinet local discharge detection device has following beneficial effect: by the detection to high-tension switch cabinet shelf depreciation, can find the equipment that there is shelf depreciation, the generation of minimizing accident.
Accompanying drawing explanation
Fig. 1 is a kind of high-tension switch cabinet local discharge detection device of the present utility model.
Embodiment
A kind of high-tension switch cabinet local discharge detection device of the present utility model, is described in detail as follows in conjunction with the accompanying drawings and embodiments.
See Fig. 1, disclosed in the utility model, a kind of high-tension switch cabinet local discharge detection device system 1, comprises sensor unit 10, filter unit 11, peak value holding unit 12, measuring unit 13 and display unit 14.
Sensor unit 10, is installed on equipment outerplanar place, for being coupled local discharge signal pass to filter unit 11.
Filter unit 11, retains useful signal for filtering clutter, and useful signal is passed to peak value holding unit 12.
Peak value holding unit 12, for keeping peak signal, and passes to measuring unit 13 by peak signal.
Measuring unit 13, for carrying out digital conversion to simulating signal, and sends to display unit 14 by numeric results.
Display unit 14, for the display to local discharge signal.
The course of work of this high-tension switch cabinet local discharge detection device 1 is:
Step 1, sensor unit 10 is coupled local discharge signal pass to filter unit 11.
Step 2, filter unit 11 filtering clutter retains useful signal, and useful signal is passed to peak value holding unit 12.
Step 3, peak value holding unit 12 pairs of peak signals keep, and signal peak is passed to measuring unit 13.
Step 4, measuring unit 13 pairs of simulating signals carry out digital conversion, and numeric results is sent to display unit 14.
Step 5, the display of display unit 14 pairs of local discharge signals.
Above process is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill of relevant technical field; when not departing from spirit of the present utility model and specification; can make a variety of changes and be out of shape; therefore all equivalent technical schemes also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
