Abstract
The utility model discloses a general anti-shedding grounding clamp used for transformer stations comprising a hollow insulation operation rod and a grounding device joint. The grounding device joint comprises an upper jaw plate and a lower jaw plate, which are connected together by a strong torsion spring. The lower part of the upper jaw plate is provided with an upper groove, and the upper part of the lower jaw plate is provided with a lower groove. The opening of the upper groove and the opening of the lower groove are cooperated with each other. The hollow insulation operation rod and the lower jaw plate are integratedly formed, and the upper jaw plate is connected with a pressing handle by the strong torsion spring and the high strength stay wire in the hollow insulation operation rod. A cylindrical wall of the middle lower part of the hollow insulation operation rod is provided with a strip-shaped opening. The pressing handle can move upwards and downwards through the strip-shaped opening in order to drive the opening or the closing of the upper jaw plate via the high-strength stay wire. When in use, the stay wire of the pressing handle is tensioned, and the force can be applied to the strong torsion spring, and then the upper jaw plate is opened; when the handle is loosened, the upper jaw plate and the lower jaw plate can be closed, and then the opening of the upper groove and the opening of the lower groove can be closed, and therefore the shedding phenomenon of the grounding wire can be prevented.
Description
technical field
The utility model relates to a kind of managing security tools and instruments that a kind of power industry is generally applied, and particularly relates to the general Anti-dropping earthing clip of a kind of transformer station.

At present, the portable grounding wire device that China electric power system is used, has according to the classification of joint form: the types such as single tongue formula, double tongue type, spiral press formula, hold flat, hedgehog hydnum formula.Wherein single tongue formula, double tongue type are mainly used in circuit or bus and have a power failure and use while doing safety measure; Spiral presses formula, hold flat, be mainly used in busbar has a power failure and uses while doing safety measure.Grounding wire device exists the reason of various ways to be mainly, for meeting the needs of difform equipment in the time that safety measure is done in power failure.
utility model content
Technical problem to be solved in the utility model is: a kind of difficult drop-off, simple in structure, easy to operate, the safe and reliable general Anti-dropping earthing clip of transformer station are provided.
The technical scheme that the utility model is taked for technical solution problem is:
The general Anti-dropping earthing clip of a kind of transformer station, comprise hollow insulating bar and earthing device joint, described earthing device joint comprises acia and maxillary plate, between described acia and maxillary plate, link together by powerful torsion spring, below described acia, be provided with upper groove and above described maxillary plate, be provided with low groove, the groove mouth of described upper groove and low groove matches each other; Described hollow insulating bar and maxillary plate are integral type structure, the high strength bracing wire of described acia by powerful torsion spring and hollow insulating bar inside with press handle and be connected, in described hollow insulating bar, on the cylindrical wall of lower end, be provided with strip gab, described in press that handle moves up and down by strip gab and then drive acia to open or closed action by high strength bracing wire; At the opening part of described acia bottom, folding bullet tongue is set, between described folding bullet tongue and acia, is provided with back-moving spring.
On described acia, the corner position of the opposite side corresponding with upper groove is provided with connection fastening bolt, and described earth connection is connected with described acia by connecting fastening bolt.
Described back-moving spring is torsion spring, or is extension spring.
The described handle of pressing is processed by insulating material.
When use, press the handle of pressing of the present utility model, high strength bracing wire tensioning, powerful torsion spring is stressed, and acia is opened, and earth lead is clamped in to the notch place of upper groove and low groove; Unclamp the handle of pressing of the present utility model, acia and maxillary plate closure, the notch of upper groove and low groove is also thereupon closed, the phenomenon of having avoided earth lead to come off.
Owing to being provided with folding bullet tongue at the opening part of the utility model acia bottom, its structure is identical with the structure of key chain folding, even if earth lead departs from from notch, because the barrier effect of folding bullet tongue also can not depart from from earthing device joint, easy to use, safe and reliable.
