Abstract
The utility model relates to a grounding wire connection device used in the transformer substation maintenance work and the high-voltage and low-voltage line maintenance work. The grounding wire connection device comprises a grounding head, and a grounding wire which is connected onto the grounding head. A connection device is connected between the grounding head and the grounding wire. One end of the connection device is connected with the grounding head through a hinge pin. A grounding wire connection plane is arranged on the connection device. A pigtail on one end of the grounding wire is fixed on the connection device. A section of grounding wire behind the pigtail is disposed on the connection plane and fixed on the connection plane through a plurality of hoops which are arranged separately. By adopting the above-mentioned structure, the phenomenon of a broken grounding wire is effectively avoided, the current-carrying capacity born by the grounding wire is ensured, good protection is provided for the grounding wire, and the construction security of field operators is ensured.
Description
Technical field
The utility model relates to the ground wire connecting device that uses in a kind of transformer station and the high-and low-voltage circuit service work.
Background technology
In the transformer station and high-and low-voltage circuit service work process of electric power system, for guaranteeing the enforcement of site safety measure, on-the-spotly all need to install keep the scene intact staff's safe construction of earth connection.But find from site inspection; earth connection of the prior art in use; because the junction of earth connection and grounding head is often crooked; wire easily fractures and disconnected burst phenomenon occurs; after earth connection fractureed, the ampacity that earth connection bears diminished, and the cross section of earth connection does not reach the standard-required of safety regulations; circuit send electricity, self power generation, electrification seasonable like this, and earth connection just can not play the staff's that keeps the scene intact effect.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly can make earth connection the end of a thread firm and reliable connection, guarantees the ground wire connecting device of site operation personnel's construction safety.
In order to solve the problems of the technologies described above, ground wire connecting device of the present utility model comprises grounding head and the earth connection that is connected on the grounding head, is provided with jockey between grounding head and the earth connection; Jockey one end is connected with grounding head by bearing pin, an earth connection is set on the jockey connects the plane, the copper nose of earth connection end is fixedly connected on the jockey, and one section earth connection behind the copper nose is placed in to connect on the plane and by several shroud rings that the interval arranges and is fixed on the connection plane.
Described jockey is made by copper coin.
After adopting above-mentioned structure; owing to being provided with jockey between grounding head and the earth connection; alleviate the suffered bending power of grounding wire connector part by jockey; effectively avoid resolving the phenomenon of thigh; guaranteed the ampacity that earth connection bears; earth connection is played a very good protection, also make site operation personnel's construction safety obtain guarantee.
Description of drawings
Fig. 1 is the integrally-built front view of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, ground wire connecting device of the present utility model is described in further detail.
As shown in the figure, ground wire connecting device of the present utility model, comprise the grounding head 1 that is installed on the joystick 8 and the earth connection 2 that is connected on the grounding head, be provided with the jockey 3 of being made by copper coin between grounding head 1 and the earth connection 2, jockey one end is connected with grounding head by bearing pin 4, an earth connection is set on the jockey connects plane 5, the copper nose 6 of earth connection end is fixedly connected on the jockey, and one section earth connection behind the copper nose is placed in to connect on the plane and by several shroud rings 7 that the interval arranges and is fixed on the connection plane.
