The technical solution of the utility model is: comprise energy electroscope and at least two section telescopic bars, the electroscope that can measure high voltage or low-voltage is installed in the top of expansion link, on the described expansion link of a uppermost joint, be in series with one group of insulator, it is characterized in that: the top of described electroscope shell and side are hermetically-sealed construction, are provided with the rain visor that outwards extends downwards in the bottom of this shell; Sealing cap is equipped with in the position that is positioned on a described uppermost section telescopic bar below the described insulator, the sealing cap is made of the installation sleeve and the sleeve of one, the upper end of sleeve is connected the lower end of installation sleeve, this installation sleeve closely is sleeved on the described expansion link, and the internal diameter of this sleeve matches with the external diameter of the upper end of a nethermost section telescopic bar.
Outer at described sleeve is provided with the brim of a hat.
Outer peripheral face in the upper end of the inner peripheral surface of described sleeve and a described nethermost section telescopic bar is provided with the concavo-convex clamping body of mutual correspondence.
Described galvanoscopic bottom end cover is made by transparent material, is provided with the test button on this bottom end cover, in this bottom end cover light emitting diode is housed, and is provided with playback gap or louver around this bottom end cover.
Described insulator was managed and be connected this axle center pipe side face by the axle center several disks constitute, and the outer of this disk is downward-sloping, is provided with the rain visor of downward protrusion in the outer of this disk; This insulator is connected with described galvanoscopic bottom end cover by an insulation rod; The upper end of this insulation rod is provided with screw rod and is connected with the nut that embeds described electroscope bottom end cover center, the lower end of this insulation rod is provided with thin bar, and this thin bar is pegged graft, is spirally connected or be bonded in the hole on described expansion link top after passing the axle center pipe of described insulator; Described insulator is made by electro-insulating rubber.
Next joint of described expansion link is handle, is with the water proof rubber ring on this handle.
The utility model has the advantages that: galvanoscopic circuit is installed in the shell of a top seal, and sleet can not enter, and has guaranteed the operate as normal of circuit; Insulator on the expansion link can prevent effectively that sleet from soaking below each disk, thereby has completely cut off the whole surface of sleet water-soaked, prevents to form conductive path, avoids the generation of electric shock accidents, thereby satisfies the needs that carry out electrical verification under the sleety weather.Sealing cap can with nethermost expansion link lock sealing, prevent that expansion link from getting loose and cause entering foreign material and water, avoid influence normal flexible and reduce insulating property.
