Background technology
Along with the development of power industry, electrical network, power regulation station are more and more, in the maintenance of various circuit, power regulation station etc., need the joint regularly using earth connection in a large number, the convenience how being grounded the sub operation of line is run into the required problem solved in operation with safety.
Up to now, what the earth connection that this neighborhood uses adopted is rotary fastening means, when hanging earthing conductor, by rotation process bar, drives joint fastening.If undue force or angle are forbidden, be difficult to grounding wire connector and wire are fitted tightly.When removing earth connection, need action bars to aim at the joint of earth connection to engage, very high requirement is proposed to operating personnel's muscle power, especially electric pressure higher position, due to safe distance requirement, action bars is long, and action bars is more wasted time and energy with docking of joint.In addition, in open type environment, the screw thread of this type of joint gets rusty easily, and is unfavorable for operation and management.
Higher for earth connection mounting distance in superhigh pressure station, there are operating personnel at present and inconvenience is installed, reduces operating time long and problem that personnel assignment efficiency is not high consuming time.
Summary of the invention
For solving the problem, the present invention is directed to the problem existing for service condition and the shortcoming of common grounding wire connector, original grounding wire connector design being improved, the object of the invention is to:
There is provided a kind of Ultra-high Voltage Substations universal vise formula grounding wire connector, the technical scheme of Ultra-high Voltage Substations universal vise formula grounding wire connector of the present invention is as follows:
A kind of Ultra-high Voltage Substations universal vise formula grounding wire connector, described Ultra-high Voltage Substations universal vise formula grounding wire connector is used for the installation of earth connection in Ultra-high Voltage Substations, it is characterized in that,
Described grounding wire connector adopts inverted u-shaped hook, directly hangs on earth point,
Fix to make both sides, two panels metallic conduction sheet (1) is set inside described inverted u-shaped hook receiver, two panels metallic conduction sheet is combined to form toroidal, make described inverted u-shaped hook receiver be convenient to hang on the earth point of electric equipment thus, and the described inverted u-shaped hook receiver left and right sides and wire fitting area increase.
According to a kind of Ultra-high Voltage Substations universal vise formula grounding wire connector of the present invention, it is characterized in that, arranging inside the described inverted u-shaped hook receiver two of two panels metallic conduction sheet (1) and spring (4) is being set between metallic conduction sheet respectively, after on the earth point making described inverted u-shaped hook receiver hang over electric equipment thus, form thrust, and the described inverted u-shaped hook receiver left and right sides and wire fitting area increase.
According to a kind of Ultra-high Voltage Substations universal vise formula grounding wire connector of the present invention, it is characterized in that, the two panels metallic conduction sheet (1) arranging spring (4) inside described inverted u-shaped hook receiver two and between metallic conduction sheet respectively forms dumbbell shape, namely closing in type in the middle of, so that form self-locking after inserting earth point.
According to a kind of Ultra-high Voltage Substations universal vise formula grounding wire connector of the present invention, it is characterized in that, earth point in transformer station is the occasion of row's shape, in order to adapt to the row's shape earth point form in transformer station, two panels metallic conduction sheet inside described inverted u-shaped hook receiver and joint are linked up with and are arranged outside spring (4) respectively between inner side, arrange metallic conduction sheet and spring equally in described inverted u-shaped hook receiver inside upper part.
Thus, the close contact of grounding wire connector and electric equipment wire is increased.
According to Ultra-high Voltage Substations universal vise formula grounding wire connector of the present invention, grounding wire connector and wire fit tightly, and handling earth connection is convenient, especially electric pressure higher position, due to safe distance requirement, action bars docks save trouble and labor with joint.Reduce the operating time, personnel assignment efficiency is high, is beneficial to operation and management.

Embodiment
Below, according to specification drawings and specific embodiments, a kind of Ultra-high Voltage Substations universal vise formula grounding wire connector of the present invention is further described in detail.
Embodiment 1
A kind of Ultra-high Voltage Substations universal vise formula grounding wire connector, described Ultra-high Voltage Substations universal vise formula grounding wire connector is used for the installation of tubular grounding line in Ultra-high Voltage Substations.
Described grounding wire connector adopts inverted u-shaped hook, directly hangs on earth point.
Fix to make both sides, two panels metallic conduction sheet (1) is set inside described inverted u-shaped hook receiver, two panels metallic conduction sheet is combined to form toroidal, make described inverted u-shaped hook receiver be convenient to hang on the earth point of electric equipment thus, and the described inverted u-shaped hook receiver left and right sides and wire fitting area increase.
Embodiment 2
Except arranging inside the described inverted u-shaped hook receiver two of two panels metallic conduction sheet (1) and arranging except spring (4) between metallic conduction sheet respectively, other are as embodiment 1, obtained a kind of Ultra-high Voltage Substations universal vise formula grounding wire connector of the present invention.After on the earth point making described inverted u-shaped hook receiver hang over electric equipment thus, form thrust, and the described inverted u-shaped hook receiver left and right sides and wire fitting area increase.
