The utility model discloses a connection device for eliminating the induced voltage of high-voltage equipment, which is provided with a hinge-type hoop and a grounding wire that are matched and connected by a transmission line, wherein the grounding wire has two sections, and one end of the first section is connected to a hinge-type The other end of the hoop is connected to the second section of the grounding wire and fixed on the aerial work vehicle. The end of the second section of the grounding wire is provided with a terminal plate, which is connected to the grounding body through bolts. Compared with the prior art, the connection is reliable, the operation efficiency is high, and the ground wire is always grounded during the demolition process, which ensures the safety of construction personnel.
Description
Technical field
The utility model belongs to the power construction technical field of tools, is specifically related to a kind of jockey of eliminating high-tension apparatus induced voltage when removing lead-in wire.
Background technology
In recent years along with the develop rapidly of electric utility, the safe operation of 1000KV ultra high voltage, 500KV has become the major network structure.Be the power supply reliability of support equipment, all will carry out preventive trial at a distance from several years, check whether conformance with standard of test data it to different model equipment is every; Sometimes in process of the test, also need the lead-in wire of power failure equipments both sides be removed,, on the equipment that has a power failure, can produce induced voltage owing near power failure equipments, also have the equipment of operation; The intensity of induced voltage higher (the particularly above electric pressure of 220KV); Can cause the staff can't operate as normal, generally be ground connection between the bottom of high-altitude operation vehicle and earth mat for eliminating the induced voltage staff, between the top of high-altitude operation vehicle and the lead-in wire that needs to remove, links to each other then again; Play the way of eliminating induced voltage like this; Though this way is often used, flow process is loaded down with trivial details, but also can not eliminate induced voltage completely.Because behind the bolt of removing anchor leg; Put to ground after the lead-in wire colligation that need will remove with rope; So just need remove the top of high-altitude operation vehicle and the earth connection that needs to link to each other between the lead-in wire of dismounting, so also have induced voltage on the lead-in wire that is removed.
The utility model content
For solving the existing above-mentioned technological deficiency that exists, it is a kind of simple in structure, easy to operate, safe and reliable that the purpose of the utility model is to provide, and eliminates the jockey of high-tension apparatus induced voltage when removing lead-in wire.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts: the jockey that this eliminates the high-tension apparatus induced voltage has hinge-type anchor ear and earth connection that power transmission line is connected; It is characterized in that: said earth connection has two sections; One end of first section earth connection connects the hinge-type anchor ear, and the other end connects second section earth connection, and is fixed on the high-altitude operation vehicle; Second section earth connection end is provided with terminal block, connects earth electrode through bolt.
Said first section earth connection has many, and an end of every earth connection connects the hinge-type anchor ear, and the other end connects second section earth connection.
Said first section earth connection is wrapped with rope.
Scribble insulating barrier on the said rope.
Adopt the beneficial effect of technique scheme: the jockey that this eliminates the high-tension apparatus induced voltage is the two-part earth connection, and is connected with high-altitude operation vehicle; When in use; Earlier that an end and the earth electrode of ground connection is fixing fastening, the staff rises to the lead-in wire place that is removed through high-altitude operation vehicle then, tightly links to each other with the lead-in wire that is removed behind the opening hinge formula anchor ear; Induced voltage will flow into the earth through the steel wire in the rope like this, and the staff just can arbitrary work.First section earth connection has many, can remove lead-in wire simultaneously, and be easy to operate.Compared with prior art, connect reliably, operating efficiency is high, and earth connection ground connection has all the time ensured workmen's safety in the process of dismounting.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Embodiment
The jockey of elimination high-tension apparatus induced voltage as shown in Figure 1; Have hinge-type anchor ear and earth connection that power transmission line is connected; Said earth connection has two sections; Said first section earth connection has many, and an end of every earth connection connects the hinge-type anchor ear, and the other end connects second section earth connection.One end of first section earth connection 4,5,6 connects hinge- type anchor ear 1,2,3 respectively; The other end of earth connection 4,5,6 connects second section earth connection 8; And be fixed on the high-altitude operation vehicle 7, second section earth connection 8 end is provided with terminal block 10, connects earth electrode 9 through bolt.Said first section earth connection is wrapped with rope, scribbles insulating barrier on the said rope.But hinge-type anchor ear, rope diameter and the steel wire diameter of different electric pressures are according to the diameter and the weight enlarged cross section of the object that carries.
When in use; Earlier that an end and the earth electrode of ground connection is fixing fastening; The staff rises to the lead-in wire place that is removed through high-altitude operation vehicle then; Tightly link to each other with the lead-in wire that is removed behind the opening hinge formula anchor ear, induced voltage will flow into the earth through the steel wire in the rope like this, and the staff just can arbitrary work.
