Abstract
The utility model provides a stride across earthing pole that river / zanjon was used, this earthing pole include two sections feed sticks, two drainage towers, two water conservancy diversion cables and an air wire, and one section feed stick is established at a drainage tower department, and another section feed stick is established in another drainage tower department, and the air wire is hung between two drainage towers, and the feed stick is connected with the air wire through the water conservancy diversion cable. The utility model discloses replace the water conservancy diversion cable to stride across river or zanjon with the air wire, shorten the water conservancy diversion cable length, practiced thrift the investment, reduce design, the construction degree of difficulty, when avoiding water conservancy diversion cable construction, operation to the destruction of river (zanjon) with influence each other, has greatly extended earthing pole utmost point location and be suitable for regionally, improve earthing pole operational safety.
Description
Technical field
This utility model relates to extra-high voltage direct-current transmission field, especially relates to a kind of earthing pole crossing over river/zanjon.
Background technology
In system for ultra-high voltage transmission, water conservancy diversion cable imports to feed rod electric current, then by feed rod, electric current is released into the earth.Due to earthing pole self-technique condition requirement, general polar ring arrangement requirement landform is mild, takes up an area about 400～700 mu, in practical implementation, is limited by local plan, basic farmland, landform etc., be difficult to search out suitable place.The layout of some earthing pole polar ring is limited by orographic condition, and as having river or bottom of trench traverse in the middle of location, pole, polar ring can not pass from river bed or bottom of trench, if transformation river course, engineering is costly, if river cannot change its course, it needs to disconnect arranges, water conservancy diversion cable also needs to handle accordingly.
Utility model content
The purpose of this utility model is in that: for prior art Problems existing, it is provided that a kind of earthing pole crossing over river/zanjon, solves the problem that existing earthing pole cannot carry out mounting arrangements in river or zanjon area.
Utility model purpose of the present utility model is achieved through the following technical solutions:
A kind of earthing pole crossing over river/zanjon, it is characterized in that, this earthing pole includes two sections of feed rod, two drainage towers, two water conservancy diversion cables and an aerial condutor, one section of feed rod is located at a drainage tower place, another section of feed rod is located at another drainage tower place, aerial condutor hangs between two drainage towers, and feed rod is connected with aerial condutor by water conservancy diversion cable.
As further technical scheme, after water conservancy diversion cable introduces from drainage tower, shallow embedding also connects feed rod.
As further technical scheme, aerial condutor and water conservancy diversion cable are same model electric wire.
As further technical scheme, feed rod is the feed rod that high-silicon chromium iron is made.
As further technical scheme, the two ends of every section of feed rod all back bend.
Compared with prior art, this utility model aerial condutor replaces water conservancy diversion cable to cross over river or zanjon, shorten water conservancy diversion cable length, save investment, reduce design, difficulty of construction, avoid water conservancy diversion cable construction, when running to the destruction of river (zanjon) with influence each other, be greatly enlarged earth electrode field suitable application region, improve earthing pole safety in operation.
Accompanying drawing explanation
Fig. 1 is structural representation during this utility model application；
Fig. 2 is the section structure schematic diagram of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Embodiment
This utility model provides a kind of earthing pole crossing over river/zanjon, its cardinal principle is: earthing pole feed rod cannot directly river crossing or bottom of trench time, adopt and cut-off feed rod in river or zanjon both sides, replace water conservancy diversion cable to connect the water conservancy diversion cable of both sides, river with aerial condutor, and then connect both sides feed rod.
As shown in Figure 1 and Figure 2, this earthing pole includes two sections of feed rod, 2, two water conservancy diversion cables 3 of 1, two drainage towers and an aerial condutor 4.Arranging a drainage tower in the side in river 6 (being alternatively bottom of trench), the opposite side in river 6 arranges a drainage tower.One section of feed rod is buried underground near every drainage tower.Aerial condutor 4 hangs between two drainage towers, and every section of feed rod is connected with aerial condutor each through water conservancy diversion cable.
After water conservancy diversion cable introduces from drainage tower, shallow embedding also connects feed rod.Aerial condutor and water conservancy diversion cable are same model electric wire.Feed rod is the feed rod that high-silicon chromium iron is made.The two ends of every section of feed rod all back bend, and form " ear " portion 5.Drainage tower adopts steel tower.
Cross over river with aerial condutor, reduce earthwork excavated volume, also reduce difficulty of construction simultaneously, it is to avoid water conservancy diversion cable construction, when running to the destruction of river (zanjon) with influence each other.Because feed rod and water conservancy diversion cable are without traverse river bed (bottom of trench), it is therefore prevented that the mechanical damage to feed rod and water conservancy diversion cable, improve earthing pole reliability of operation and safety.Replacing water conservancy diversion cable with wire, that reduces water conservancy diversion cable makes consumption, improves economy.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; it should be pointed out that, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
