Description
Technical field
The utility model relates to shocking preventing technology, espespecially a kind of galvanic protection earthing pole.Be applicable in the conglomerate ground systems such as Traction Substation of High Speed Railway, direct current power substation, enterprise's non-utility substation.
Background technology
Rail traction substation ground network is the critical facility that electric locomotive traction is powered, and is the important leverage of equipment and personnel safety, on average within every 5 ~ 10 years, need transform, costly.The earth mat protection against corrosion of current the sector mainly contains two schemes: one be adopt corrosion resistant and possess conductivity material replace common material.Two is adopt resist technology to extend the working life running earth mat.
Adopt corrosion resistant and possess conductivity material replace common material, be generally build using at the beginning.Because the nano material of conductivity anticorrosionly can be had again all costly, so cost of investment is high, be difficult to widely use.For the earth mat built for many years, need when replacing as adopted the corrosion resistant material possessing again conductivity dig on a wide area earth mat and backfill earth mat, its change needed for construction cost also very high, also inconvenience popularizes.
If select to have erosion-resisting electro-conductive material (as fine copper rod), then owing to because battery effect accelerated corrosion steel earth mat (reinforcing bar in buildings), thus can accelerate the corrosion of earth mat (reinforcing bar in buildings) between copper-iron, this scheme is inadvisable.
Also has a kind of impressed current protection technology that adopts to extend the mode of the working life running earth mat.It utilizes external dc power supply, is connected by protected metal with power cathode, makes it become negative electrode and reach the object preventing metallic corrosion.But; in rail traction substation or direct current power substation; due to the stray current that outwardness in earth mat is a large amount of; and the directive uncertainty of stray current; this just cannot provide lasting, clean, that directivity is consistent electric current for protected object, and institute cannot use in this way in such substation.
Summary of the invention
The utility model technical issues that need to address are, one be overcome for the earth mat built for many years, as adopt the corrosion resistant material possessing again conductivity replace needed for the high deficiency of construction cost; One is overcome to select fine copper rod to make electro-conductive material, then owing to producing the deficiency of battery effect accelerated corrosion steel earth mat between copper-iron; Three is overcome to adopt impressed current protection technology due to a large amount of stray current of outwardness in the earth mat of rail traction substation or direct current power substation, cannot provide the deficiency of lasting, clean, that directivity is consistent electric current for protected object, provides galvanic protection earthing pole.While the common material of use does earthing pole, reduce the corrosion to the main earth mat of steel and building concrete reinforcing bar by " sacrificial protection ", thus extend earth mat and Building life cycle.
For this reason, the utility model is by the following technical solutions:
Galvanic protection earthing pole; comprise the setting earthing pole of copper sheathed steel bar construction; erect earthing pole and be arranged in anode column as ground electricity anode, anode column adopts magnesium or aluminium or zinc or manganese material to make, and forms magnesium anode or aluminum anode or zinc anode or manganese anode.
Technique scheme is further elaborated:
The epimere conduction erectting earthing pole connects ground lead, and ground lead is for conducting electricity connection earth mat.
Anode column upper end and lower end and setting earthing pole connecting portion fill out filling resin respectively.Mainly prevent from erectting the corrosion of earthing pole root, after erectting the corrosion cracking of earthing pole root, the anode be attached on earthing pole barred body departs from, thus shortens the work-ing life of product.
The centre hole of anode column is shaped with internal thread, erects earthing pole and is shaped with outside screw, and anode column is spun by internal and external threads with setting earthing pole.
Erect the outside screw tip respectively, lower end of earthing pole.
Working mechanism of the present invention is as follows:
Magnesium-aluminum-manganese based material possesses more negative metal current potential; be reliably connected by good conductor and protected metal; the more volatile de-electronation of anode metal self; by conductor to protected metal carrying supplied for electronic; the current potential of protected metal is moved to negative bias; enter Mian Fu district, protected and no longer corrode.
Using magnesium-aluminum-manganese based material as protection pole; be connected with main earth mat or building concrete reinforcing bar nearby and form electrolyzer; the magnesium-aluminum-manganese based material that reductibility is stronger will consume as anode generation oxidizing reaction, and protected main earth mat or building concrete reinforcing bar just can avoid corrosion as negative electrode.
Visible, the utility model, on increase the ground network area basis, can reduce the corrosion to the main earth mat of steel and building concrete reinforcing bar, extends the earth mat life-span, architecture protection thing safety.
The beneficial effects of the utility model are:
Copper sheathed steel earthing pole and magnesium-aluminum-manganese system anode combine by galvanic protection earthing pole efficiently; both while having reached composition stereo grounding mesh; well reduce again the corrosion of the main earth mat of steel and building concrete reinforcing bar by " sacrificial protection ", thus extend earth mat and Building life cycle.
