Technical Field

The invention relates to the technical field of ultrahigh frequency partial discharge detection of electric appliances, in particular to a GIS ultrahigh frequency live-line detection shielding device storage device.

Background

In the 80 s of the 20 th century, an ultrahigh frequency method for partial discharge detection was found in a laboratory and was included in the category of live-line detection items of a Gas Insulated Switchgear (GIS) in 2010. However, due to the fact that multiple devices are arranged in the transformer substation and space signals are complex, when ultrahigh frequency partial discharge detection is performed on the nonmetal-shielded basin-type insulator combined electrical apparatus, various interference signals appearing in the external environment can be conducted into the device through the insulating basin of the GIS, confusion and coverage are caused to the test results, erroneous analysis results such as misjudgment and missing judgment are caused, smooth development of ultrahigh frequency partial discharge test work is affected, and therefore the external interference signals need to be removed.

At present, a method for detecting shielding interference by partial discharge ultrahigh frequency is to use an aluminum foil to wrap a basin-type insulator, but the method has the defects that an aluminum foil paper is easy to break, fragile and light in weight, and the like, so that incomplete shielding can be caused, metal fragments can fly to influence the operation safety of power transformation equipment, and meanwhile, the method also has the defects of low use efficiency and high aluminum foil consumption.

Therefore, an external signal interference shielding device which is safe, reliable, efficient to use, convenient to operate and material-saving is developed.
