The whole device is characterized in that 1, components which pass through the current guiding wire clamp, the wire connecting ring and the earthing ring can be easily engaged with an insulation lead wire protection sleeve; and the device is advantaged by lead wire damage-free property, firmness and reliability, and greatly shortened power cut operation time; 2, the umbrella skirts and the insulation core rod are designed to be of an integrated structure, and therefore the device is advantaged by superior electric property, high mechanical strength, and operation safety; 3, the silica gel umbrellas are made of silica gel, therefore the internal insulation can be prevented from being affected with damp, a preventive insulation monitoring test is not need, cleaning work is not needed, a daily maintenance workload is reduced, and the service life is greatly prolonged; and 4, the device is advantaged by small overall structure, light weight, and convenience of transport and installation.
Description
Technical field
The utility model relates to the electric equipment technical field, particularly a kind of cable termination suspension type earthing device.
Background technology
Along with urban network restructuring and new Rural Electrification Construction, the 10KV distribution carries electrical network all to realize standardization and insulating operation in recent years.In order to ensure distribution low voltage electric network security of operation, stable.Need regularly these controller switching equipments to be safeguarded, maintenance work comprises transformer oiling, gear shift, installation anti-theft lock, changes disconnecting link in JP (distribution transformer integrated power distribution cabinet) cabinet, changes table meter instrument transformer, A.C. contactor, air switch etc.First the place branch line is had a power failure in the practice of construction operation, dismounting transformer and JP (distribution transformer integrated power distribution cabinet) cabinet is hung again, due to, traditional distribution line is that exposed steel reinforced aluminium conductor is as the transmission pressure of distribution, exposed line can articulate earth point in any place, the many electric contacts in net power distribution station, city are all exposed, relatively articulate earth point all more convenient.But the construction requirements along with national intelligent grid.The distribution transmission line requires to use insulated conductor, becomes each electric contact of platform and all carries out the insulating transformation.Require all electric electric contacts places all to want insulating wrapped; Requirement is operated in high and low pressure side in the power distribution station all will mount earth connection and electrical verification.If after the transformation of distribution all insulation, earth connection does not just have the place to articulate, and does not have the place to look for the electrical verification point simultaneously yet.Make ground wire articulate and become loaded down with trivial details, maintenance is very inconvenient.Cause construction maintenance personnel's working strength large, the Construction and Maintenance difficulty is high, the activity duration is long.In addition, usually have a plurality of transformers on the 10KV circuit, can cause larger area to break, have a power failure when the many places transformer breaks down simultaneously, cause serious economic loss.
The utility model content
The purpose of this utility model is to provide a kind of novel structure, easy accessibility, safe and reliable transformer column hanging device.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of cable termination suspension type earthing device comprises support, horizontally takes, electric contact insulating sleeve, full skirt and insulation mandrel, is provided with drainage ply-yarn drill, connecting ring and ground loop in described electric contact insulating sleeve.
Described ground loop and support are parallel arrangement.
Described full skirt and insulation mandrel are the integral type structure.
The material of described ground loop is almag.
Described electric contact insulating sleeve can be red, green, yellow three looks.
The material of described full skirt is insulation silica gel.
The utility model comprises support, horizontally takes, electric contact insulating sleeve, full skirt and insulation mandrel, is provided with drainage ply-yarn drill, connecting ring and ground loop in the electric contact insulating sleeve.And full skirt and insulation mandrel are designed to integral structure.Whole device has following characteristics: 1, can easily realize directly interlock on the insulated conductor sheath by the parts of drainage ply-yarn drill, connecting ring and ground loop, then coordinate torque spanner just equipment can be quickly installed on insulated conductor.Neither injury destroys wire, and is solid and reliable again, greatly shortened the power failure operating time, and the electric quantity loss that is caused by the test maintenance significantly descends.2, full skirt and insulation mandrel are designed to integral structure, make the electric property of device superior, mechanical strength is high, security of operation.3, the silica gel umbrella adopts insulation silica gel to make, and makes it have good hydrophobicity performance, and in guaranteeing, insulation is not made moist, and need not carry out preventative insulating monitoring test, does not need cleaning, has reduced the line service amount, has also greatly promoted useful life simultaneously.4, overall structure is small and exquisite, lightweight, is convenient to transportation and installs.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the supporting structure schematic diagram;
Fig. 3 is the connecting ring structural representation;
Fig. 4 is electric contact insulating sheath structure schematic diagram.
In figure: 1, support, 2, clamp nut, 3, horizontal taking, 4, full skirt, 5, ground loop, 6, connecting ring, 7, the electric contact insulating sleeve, 8, the drainage ply-yarn drill, 9, insulation mandrel.
Embodiment
A kind of cable termination suspension type earthing device as shown in the figure, comprise support 1, horizontally take 3, full skirt 4 and the insulation mandrel 9 of electric contact insulating sleeve 7, insulation silica gel, be provided with the ground loop 5 of drainage ply-yarn drill 8, connecting ring 6 and almag in described electric contact insulating sleeve 7.Ground loop 5 is parallel arrangement with support 1, and described full skirt 4 and insulation mandrel 9 are the integral type structure.
During use, first support 1 is fixedly mounted on corresponding electric pole, with the parallel installation of cross-arm 3 and lightning arrester, and fixing with clamp nut 2.Then the ground loop 5 of almag is in the same place with drainage ply-yarn drill 8 is combined and spliced, and in the pile head lead access connecting ring 6 with lightning arrester, rear fixing with clamp nut 2, prevent that lead-in wire from becoming flexible, dropping.At last electric contact insulating sleeve 7 is arranged on drainage ply-yarn drill 8 outsides, completes whole installation process.When needing power supply to use, the hanging device of ground connection directly is articulated on the ground loop 5 of almag and just can comes into operation.Described electric contact insulating sleeve 7 can for red, green, yellow three looks, for the ease of phase-splitting, improve speed and the fail safe of maintenance circuit in addition.
