Embodiment

[0015] The invention provides a ground electrode for crossing rivers / deep trenches. The main principle is: when the ground electrode feed rod cannot directly cross the river or the bottom of the ditch, the feed rods are used to cut off the feed rods on both sides of the river or deep ditch, and the overhead wires are used to Instead of diversion cables, connect the diversion cables on both sides of the river, and then connect the feeder rods on both sides.

[0016] Such as figure 1 , figure 2 As shown, the ground electrode includes two sections of feeder rods 1 , two diversion towers 2 , two diversion cables 3 and an overhead conductor 4 . One side of river 6 (also can be ditch bottom) is provided with a diversion tower, and the other side of river 6 is provided with a diversion tower. A section of feeder rod is buried near each diversion tower. The overhead wire 4 is hung between two diversion towers, and each feeder rod is connected with the overhead wire through a diver...

Abstract

The invention provides a grounding electrode for spanning a river / deep ditch. The grounding electrode comprises two feed rods, two current guiding towers, two current guiding cables and an overhead wire, wherein one feed rod is arranged at one current guiding tower, the other feed rod is arranged at the other current guiding tower, the overhead wire is hung between the two current guiding towers, and the feed rods are connected with the overhead wire through the current guiding cables. The grounding electrode has the advantages that the overhead wire replaces the current guiding cables to span the river or the deep ditch, the length of the current guiding cables is reduced, investment is reduced, design and construction difficulties are lowered, destruction of and influence on the river (the deep ditch) during the construction and operation of the current guiding cables are avoided, the applicable regions of grounding electrode addresses are expanded greatly, and the operation safety of the grounding electrode is increased.

Description

technical field [0001] The invention relates to the field of ultra-high voltage direct current transmission, in particular to a ground electrode for crossing rivers / deep trenches. Background technique [0002] In the UHV power transmission system, the current guide cable guides the current to the feeder rod, and then the feeder rod releases the current into the earth. Due to the technical requirements of the ground electrode itself, the general layout of the pole ring requires a flat terrain, covering an area of ​​about 400 to 700 mu. In practical engineering applications, it is difficult to find a suitable site due to limitations of local planning, basic farmland, and terrain. The layout of some grounding pole rings is limited by terrain conditions. For example, there is a river or ditch bottom passing through the middle of the pole site, and the pole ring cannot pass through the river bottom or ditch bottom. The layout needs to be disconnected, and the guide cable also ne...
