Abstract
The utility model discloses a novel general grounding device of a transformer station. The novel general grounding device comprises a hollow insulation operation rod and a grounding device connection head, wherein the grounding device connection head comprises an upper jaw board and a lower jaw board, which are connected with each other through a high strength torsion spring, an upper groove is disposed below the upper jaw board, a lower groove is disposed above the lower jaw board, and a groove opening of the upper groove matches a groove opening of the lower groove; the hollow insulation operation rod and the lower jaw board are of an integrated structure, the lower jaw board is connected with a pressing handle through the high strength torsion spring and a high strength drawing wire at the internal part of the hollow insulation operation rod, a strip shaped opening is disposed on a cylinder wall at a middle lower end of the hollow insulation operation rod, and the pressing handle drives the upper jaw board to carry out an open action and a close action through the high strength drawing wire by moving the strip shaped opening up and down. When the drawing wire of the pressing handle is tensioning, the upper jaw board will subject to a force, thereby opening the upper jaw board, and when the handle is released, the upper jaw board and the lower jaw board are closed, and the groove openings of the upper groove and the lower groove will be closed accordingly, so that a dropping off phenomenon of grounding wire is avoided.
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 earthing device of a kind of Novel transformer substation.
Background technology:
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, holds flat, is mainly used in when safety measure is done in busbar power failure and uses.Grounding wire device exists the reason of various ways to be mainly, for meeting the needs of difform equipment when 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 earthing device of Novel transformer substation are provided.
The utility model is that the technical scheme that technical solution problem is taked is:
The general earthing device of a kind of Novel transformer substation, comprise hollow insulating bar and earthing device joint, described earthing device joint comprises acia and maxillary plate, between described acia and maxillary plate, by powerful torsion spring, link together, 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.
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.
The described handle of pressing is processed by insulating material.
During 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 are closed, and the notch of upper groove and low groove is also thereupon closed, guarantees that earth lead does not come off.
The utility model is simple in structure, safe and reliable, easy to use, has solved earth lead in prior art and has held caducous problem, has good practical value and marketing prospect.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
