Description

A kind of electrical verification grounding apparatus that is applied to high-altitude controller switching equipment
Technical field
The utility model relates to a kind of electrical verification grounding apparatus that is applied to high-altitude controller switching equipment.
Background technology
In the middle of power line construction, in order to guarantee construction safety, before construction, must carry out electrical verification hanging earthing conductor, existingly to high-altitude controller switching equipment, adopt bucket arm vehicle to carry out electrical verification, installing earth connection, while using bucket arm vehicle to carry out operation, require circuit or equipment in smooth roadside, road gradient must not surpass 5%, and width of roadway is greater than 8 meters (assurance the coast is clears), has limited to operating location.As run into when high-low pressure is joint used or many times are joint used, use the safe distance of bucket arm vehicle inadequate.Having is exactly artificial pole-climbing electrical verification, installing earth connection again, and artificial pole-climbing exists the risk of falling from high altitude and the risk that personnel get an electric shock, and pole-climbing meeting delays a lot of time, makes the time of construction compressed.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of simple in structure, easy to carry, assembling and is applied to flexibly the electrical verification grounding apparatus of high-altitude controller switching equipment.
The utility model adopts following scheme to realize: a kind of electrical verification grounding apparatus that is applied to high-altitude controller switching equipment, comprise expansion link, described expansion link upper end is provided with the hook that Open Side Down, on described hook, be connected with the downlead that extends to ground, described expansion link is formed by connecting through fixture by more piece support bar, described fixture comprises the retaining sleeve that is set in lower joint post upper and the holding ring that is set in joint support bar lower end, upper joint support bar passes holding ring and inserts the mesopore of retaining sleeve, described retaining sleeve peripheral part is provided with external screw thread, holding ring inwall is provided with the internal thread matching with external screw thread, described retaining sleeve upper end is provided with the taper closing in that is positioned at external screw thread top, holding ring upper end is provided with taper reducing, described taper on closing up, be evenly equipped with several axial narrow tanks so that retaining sleeve and holding ring while screwing taper reducing withstand taper closing in outer circumferential side and force it to tighten up to clamp joint support bar.
Further, be provided with ∧ shape bayonet socket in the opening of described hook, described ∧ shape bayonet socket is connected with the upper end of described downlead, lower end connecting earthing device or the electroscope of described downlead.
Further, described holding ring and retaining sleeve peripheral part are provided with anti-skid design.
Compared with prior art, the utlity model has following beneficial effect: this electrical verification grounding apparatus that is applied to high-altitude controller switching equipment is simple in structure, reasonable in design, and according to the height of high-altitude controller switching equipment, can extend arbitrarily the height of this equipment, easy to carry, simple to operate, the activity duration is short, and assembling flexibly, can be applicable to various operating locations, operating personnel do not need to carry out high-altitude application simultaneously, guarantee operating personnel's safety, avoid the risk of falling from high altitude and electric shock.
