Abstract
A rain and snow prevention electroscope with insulation is provided which comprises of telescopic handle and electroscope connected on the top of telescopic handle, wherein, top and side of crust of electroscope is seal structure, waterproof brim extended to lateral and downwards is set on the bottom of crust; a set of insulation is on the telescopic handle in series. The present invention has the advantages of that: electroscope is set on a crust with airproof top and the rain and snow can't enter to ensure common work carried on; insulation on telescopic handle avoids efficiently rain and snow soaked every dish to isolate rain and snow soaked the whole surface to prevent forming conductive pathway and avoid electric shock accident to meet the requirement of electricity testing in rain and snow weather.
Description
Technical field
The present invention relates to a kind of rain and snow electroscope of tape insulation, whether check maintenance circuit is charged when being used for the maintenance of electric power networking.
Background technology
Necessary security when electroscope is the maintenance of electric power networking is taken precautions against equipment, and whether at first test maintenance objects between keeping in repair charged, causes the circuit energising and causes security incident with reason beyond preventing.Existing electroscope mainly comprises electroscope and expansion link, and electroscope is connected the top of expansion link.Galvanoscopic top is provided with induction electrode, and galvanoscopic circuit is installed in the insulation crust, and shell is fixedly connected on the top of expansion link.Pull out expansion link during electrical verification, the handle of hand-held expansion link lower end, near electric wire, if electric wire is charged, electroscope just sends the sound and light alarm signal with electrode.The major defect that this electroscope is deposited is galvanoscopic shell blow-by, and expansion link does not have water resistance yet, is running in the sleety weather water inlet cisco unity malfunction in the electroscope shell; The back side of expansion link is soaked and will be conducted electricity by sleet.So present electroscope can not use at sleety weather, otherwise will electric shock accidents take place and jeopardize the life of testing crew.Under general situation, the electric network fault that sleety weather occurs can keep in repair after weather takes a turn for the better again and allow, but special weather again, as the rare sleet disaster that occurs of the ALFISOL IN CENTRAL of China again in winter to the early spring in this year (in January, 2008～February), the loss of growing and causing of duration is big not to be seen in decades.When running into this long-term inclement weather again, the electric power worker has to avenge weather maintenance electrical network in the rain, and existing electroscope just can not satisfy the requirement that places under this inclement weather again, brings very big inconvenience to construction.
Summary of the invention
Purpose of the present invention just provides a kind of rain and snow electroscope of tape insulation, with solve that prior art exists when the sleety weather maintenance electrical network can not waterproof and cause the problem of leaking electricity.
Technical scheme of the present invention is: comprise electroscope and expansion link, electroscope is connected the top of expansion link, 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; On described expansion link, be in series with one group of insulator.
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, and the lower end of this insulation rod is provided with thin bar, and this thin bar passes pegs graft behind the axle center pipe of described insulator or be bonded in the hole on described expansion link top; Described insulator is made by electro-insulating rubber.
Be provided with the waterproof jacket of soft tubulose on described expansion link, its integral body is made by resilient material or non-elastic material; The top of the integral body of making at non-elastic material is provided with loose collar; The top of this waterproof jacket closely is enclosed within outside the flange of lower end of described insulator axle center pipe, and the integral body of this waterproof jacket covers the big portion of described expansion link or all.
Sealing shroud is equipped with in upper end at each joint of described expansion link, fixedlys connected with the upper end of each joint of expansion link in the bottom of sealing cover, and the top seal that sealing is overlapped is enclosed within the surface of a section telescopic bar slidably.
Next joint of described expansion link is handle, is with the water proof rubber ring on this handle.
Advantage of the present invention is: 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.
