The said low pressure radome of the outer setting of said high-tension shielding cover.Said high-tension shielding cover and the coaxial setting of said low pressure radome.
The high-tension shielding cover of the utility model is electrically connected with said high-voltage line, and the low pressure Shielding Case grounding can improve Electric Field Distribution effectively, eliminates induced electricity, ensures the fail safe of electric line.
The tubular shielding new cover that said high-tension shielding cover adopts copper mesh to process.Said shielding new cover adopts the stretching copper mesh, the shielding new cover that also can process for aluminium net, aluminium alloy net, stainless (steel) wire.
The two ends up and down of said shielding new cover are provided with flange, so that eliminate burr.
Said shielding new cover is provided with diamond hole, and the length of side of said diamond hole is 2-3mm.Said shielding new cover is provided with other passes, like hexangle type, circular hole, triangular form, fish scale hole.
Said low pressure radome comprises an annular stent, is wound in the screen that the semi-conducting material on the said annular stent is processed, and is provided with lead in the said screen, the lead that said lead adopts the coiling of tin-coated copper conductor to form.
Said low pressure radome is provided with four grounded at least terminal, and at least one said earth terminal is connected with lead.Said low pressure radome reliably is connected with ground, guarantees can not cause the discharge that suspends.
Because the low pressure radome is provided with the screen that semi-conducting material is processed; The residing high voltage electric field of each point position is different; There is potential difference in point-to-point transmission, might form internal current, so low pressure radome diverse location each point is necessary reliably to connect with conductor or conductive materials; Force ground connection then, change internal electric field and distribute.
