Abstract
A grounding device for a high-tension cable branch box comprises an electric conductor 1 and an insulated operating rod 5, wherein a hexagonal nut 2, a grounding wire terminal 3 and a spacing copper sleeve 4 are arranged on the electric conductor 1; an M12 internal thread 6 is arranged at one end of the electric conductor 1 while an external thread 7 is arranged at the other end thereof; the insulated operating rod 5 serves as a mounting instrument; and a hexagonal sleeve 8 with a built-in round gasket 9 and a spring 10 is embedded at one end of the insulated operating rod while an insulated handle 11 is arranged at the other end thereof. The utility model provides a man-made short-circuiting device suitable for being hung on both sides of the line of the high-tension cable branch box at the working point, and is proved by on-site experiments to have the advantages of economy, safety and reliability as compared with the prior technical products such as grounding cable heads of European or American cable branch boxes.
Description
Technical field
The utility model relates to a kind of conductive connecting device, particularly a kind of high voltage cable branch box earthing device.
Background technology
Adopt the high voltage cable branch box distribution under the entoilage of city in the cable line, adopt ring main unit to realize that the city net pulls the looped network supply power mode simultaneously, European or American cable branch box extensive use, be characterized in bi-directional door, utilize wall bushing as connecting busbar, have advantages such as length is little, the cable arrangement is clear, can realize 6 branches turnover line, installation is simple, easy to operate and hermetically sealed.But high voltage cable branch box has only casing ground connection, no circuit grounding function, there is potential safety hazard, for overcoming potential safety hazard, need to hang man-made short-circuit's earthing device, and on-the-spot earth point should be selected in arbitrary end of an interior working end of " working point " feeder pillar and a last feeder pillar at high pressure feeder pillar circuit two ends, working point.
Summary of the invention
The purpose of this utility model is to provide a kind of high voltage cable branch box earthing device.It can be more effective overcome the potential safety hazard that is present in " working point " high pressure feeder pillar circuit two ends, guarantees to construct, the personal safety of installation, trouble hunting personnel etc.
The technical scheme that solves the utility model skill sample problem is: this device comprises electric conductor 1, hexagonal (hexagon)nut 2, binding post 3, spacing copper sheathing 4 and insulation hook stick 5.One end of electric conductor 1 is provided with internal thread 6, and its other end is provided with external screw thread 7, and insulation hook stick 5 one ends stud with interior Hexagonal jacket, ring washer 9, spring 10, and its other end is that insulated handle 11,12 is an earth connection.The M of electric conductor 1
12Female thread portion is used for fixing the conduction stud of feeder pillar inner cable head, binding post 3, spacing copper sheathing 4 are used for fixing earth connection, the Hexagonal jacket of utilization insulation hook stick 5 cooperates with the hexagonal (hexagon)nut on being fixed on electric conductor, whole grounding wire device is fixed on the feeder pillar cable end, realizes feeder pillar line-to-ground function.
The utility model is on probation through the job site, and, safety more economical than the prior art product are seen attached list.The high voltage cable branch box earthing device on the basis of former casing ground connection, has been realized the line-to-ground function by setting up artificial earthing's device, has not only solved the Voltage Cable Lines Construction problem with grounding but also further improved working security.For line upkeep, overhaul of the equipments provide safety guarantee.The high voltage cable branch box earthing device is simple in structure, and is easy to operate.The high voltage cable branch box earthing device is except providing the line-to-ground function, can also be applied to the lead-out wire of cable line test and unit check, saved investment for purchasing the relevant cables auxiliary equipment, it is applicable to high-tension cable feeder pillar ground connection such as European, American, and it is widely used.

Embodiment;
Referring to accompanying drawing 1 and Fig. 2, the utility model comprises electric conductor 1 and insulation hook stick 5, hexagonal (hexagon)nut 2, binding post 3, spacing copper sheathing 4 are housed on the electric conductor 1, one end of electric conductor 1 is provided with internal thread 6, its other end is provided with external screw thread 7, and Hexagonal jacket 8, ring washer 9, spring 10, its other end were held handle 11 for insulation in an end of erecting tools insulation hook stick 5 studded with.The M of electric conductor 1
12Internal thread 6 is used for fixing on the conduction stud of feeder pillar inner cable head, binding post 3, spacing copper sheathing 4 are used for fixing earth connection 12, the hexagonal copper sheathing of utilization insulation hook stick cooperates with the hexagonal (hexagon)nut on being fixed on electric conductor, whole earthing device is fixed on the feeder pillar cable end, realizes feeder pillar line-to-ground function.
Subordinate list:
| Product | Fail safe | Economy | Need the time | Difficulty |
| 1, earth connection cable end | Safety.Dial slotting formula earth cable head by the special use of manufacturer production and belong to matured product, good insulation preformance. | Uneconomical, every feeder pillar needs 3000 yuan input could realize the line-to-ground function. | Need to add assembly parts every feeder pillar power failure.Installation process is longer. | Improve the process difficulty, can not realize for the moment. |
| 2, the utility model | Safety.Overall process is used the insulating rod operation. | Economical.The related accessory material of earthing device is from the processing of selecting materials, invest less, about 300 yuan. | Need with the time short.Conductor part and earth connection are an integral body, and operation settles at one go, have shortened the time that hangs earth connection. | Simply.Operation link is few, can settle at one go to hang earth connection. |
