Description
Technical field
The utility model relate to a kind of in, the ground connection of the ground used of low-voltage distribution net safety protective earthing device draws lower conductor, the insulation protection earth rod (can abbreviate the JBJY rod as) between the earth electrode of particularly a kind of ground lead that is used to be connected controller switching equipment and underground earth electrode.
Background technology
At present, in the town and country, the ground connection of the transformer platform of low-voltage network, on-pole switch equipment and low-voltage distributing line, factory, building house lead in point, skyscraper etc. all are provided with the security protection earthing device by the rules regulation and stipulation, and are the part of earthing device as the earth rod that ground connection is on the ground drawn lower conductor.Earth rod between the earth electrode of existing ground lead that is used to be connected controller switching equipment and underground earth electrode generally adopts steel strand wire, exposed reinforcement, band steel or aluminum conductor, all very easily corrosions of tie point of most earth rods and earth electrode, its serious consequence also easily makes power distribution network security protection ground connection wreck or earth rod is lost except that the tie point loose contact.Particularly, jeopardize the safe operation of power distribution network occurring bringing very big hidden danger can for personal safety and equipment operation under the fortuitous events such as line fault, thunder and lightning attack and downlead disconnection.The specification disunity of existing various earth rods, profile is not attractive in appearance yet, also influences traffic sometimes.The hidden danger that the design people once existed at existing earthing device; set out a kind of " insulation protection down conductor " (patent announcement number for CN2520573Y); dock the more and more higher requirement of ground quality with controller switching equipment according to distribution technique; the regulation of the rules standard of basic symbols splice grafting ground device relevant criterion has realized controller switching equipment reliability service, safe power supply that power department is advocated energetically.But find in the practical application that it still has unsatisfactory part, be the joint portion of the upper end of its metal core wire to the insulating protective layer end, damage easily when exposed end is coated with the zinc coat operation on to metal core wire, water or wet gas enter the insulating protective layer inner chamber also can cause the heart yearn corrosion, influence protection ground connection effect.Therefore, should in time be improved, so that eliminate the hidden danger of its existence to above-mentioned earthing device.
The utility model content
The purpose of this utility model provides a kind of insulation protection earth rod; it overcome thoroughly that existing earth rod exists with earth electrode tie point shortcoming such as corrosion very easily; its compact conformation; install, detect very convenient; grounding safety is reliable; non-maintaining, anticorrosion, antitheft, help personal safety and power distribution network safe operation.
The purpose of this utility model is achieved in that this device comprises and is connected with the controller switching equipment ground lead respectively and the line rod that firmly is connected with underground earth electrode, its technical essential is: described line rod is made of metallic conductor heart yearn and the insulating protective layer that coats the single injection-molded of its periphery, at upper and lower end to the outer surface that extends to insulating protective layer inner chamber end of metallic conductor heart yearn anticorrosion conductive layer is set.
Because the insulating protective layer that the metallic conductor heart yearn periphery of the utility model line rod coats adopts single injection-molded; and anticorrosion conductive layer is set at upper and lower end to the outer surface that extends to insulating protective layer inner chamber end of metallic conductor heart yearn; so its compact conformation, overcome thoroughly that existing earth rod exists with earth electrode tie point shortcoming such as corrosion very easily.Upper and lower end to the outer surface that extends to insulating protective layer inner chamber end at the metallic conductor heart yearn is provided with anticorrosion conductive layer, can make that the metallic conductor heart yearn of line rod upper end is easier to be connected with the ground lead of controller switching equipment, the metallic conductor heart yearn of line rod lower end is easier to be integrally welded with earth electrode, thereby make installation, detect very convenient, grounding safety is reliable, guarantee that each tie point is connected firmly and contacts reliably, and make uniform specification, increase the aesthetic appearance that is connected with controller switching equipment.This device can not only reach freedom from repairs, anticorrosion, antitheft purpose, and helps personal safety and power distribution network safe operation.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
Embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1-2.This device comprises and being connected with controller switching equipment ground lead (not shown) respectively and the line rod that firmly is connected with underground earth electrode (not shown), and its center line rod is made of metallic conductor heart yearn 2 and the insulating protective layer 3 etc. that coats the single injection-molded of its periphery.The specification of metallic conductor heart yearn 2, shape can be determined according to actual needs.Insulating protective layer 3 adopts insulating material such as polyethylene or crosslinked polyethylene, and the thickness of protective layer is selected by insulating requirements.On metallic conductor heart yearn 2, bottom to the outer surface that extends to insulating protective layer 3 inner chamber ends is provided with anticorrosion conductive layer 1, removing the easier upper end of metallic conductor heart yearn 2 that makes welds with the ground lead employing of controller switching equipment respectively, crimping is connected with clamping with outside the earth electrode welding of the lower end that makes metallic conductor heart yearn 2 and underground earth electrode etc. firmly is connected, can also guarantee metallic conductor heart yearn 2 on, bottom to joint portion exposed end on to metallic conductor heart yearn 2 of insulating protective layer 3 ends is coated with the zinc coat operation or when exposed end carries out weld job down, the set anticorrosion conductive layer 1 of the outer surface of this joint portion is not damaged, anti-effectively sealing or wet gas enter the inner chamber of insulating protective layer 3, to avoid causing inner chamber that the corrosion of the metallic conductor heart yearn 2 of 1 section of anticorrosion conductive layer is not set.
During the site operation operation; the lead-in wire that metallic conductor heart yearn 2 upper ends of this insulation protection earth rod and controller switching equipment is needed ground connection reliably is connected with welding, wire clamp clamping or with crimping plate crimping etc.; it is integrally welded that ground surface following prescribed depth and earth electrode are stretched in the lower end, and weld seam partly is coated with anticorrosion electric conducting material and gets final product.
The utility model is suitable for various power distribution equipment ground leads, also is suitable for the transformation to existing defective earth connection.When existing down conductor was transformed, handled by above-mentioned connection the upper end, and subsurface digs to former earth electrode place, and with the lower end and the welding of former earth electrode of this device, weld seam partly is coated with anticorrosion electric conducting material, and banketing gets final product.
