Abstract
The utility model discloses a novel anti-corrosive grounding body with a cathode protecting function, which comprises a steel bar body, wherein the steel bar body is provided with one or a plurality of anode mounting grooves with wide inside and narrow outer portions. Anode materials serving as anodes are arranged in the anode mounting grooves. The anode materials are zinc or zinc alloy, magnesium or magnesium alloy, alloy zinc, zinc and magnesium alloy, magnesium, magnesium alloy or other anode alloy materials. The novel anti-corrosive grounding body enables protecting current to be uniformized, can directly replace an original grounding body to perform construction, does not increase workload compared with construction of an existing grounding grid, is low in cost, does not require excessively added investment, accordingly reduces danger of theft, and prolongs service life of the grounding grid.
Description
Technical field
The utility model relates to the novel grounded body of a kind of protection against corrosion, particularly relates to a kind of novel grounded body of protection against corrosion with galvanic protection function.
Background technology
Etching problem is to bury ground steel ground net operating one puzzlement greatly; The corrosion of ground net: the most serious corrosion location, usually at subsurface 30 ~ 80cm place of down conductor part, its reason is that interior moisture of this position soil and oxygen freedom are unobstructed, adds the influence that downlead receives stronger leakage current.
The physicochemical property of soil are to burying the influence of ground steel ground net corrosion, the leakage current that induction produced between transmitting line and the shaft tower, and through the downlead ground net of flowing through, this is another important factor that causes the earth mat metallic corrosion.Because down conductor closely shows and carry bigger fault current, lightning current or leakage current density than earth mat branch conductors, the corrosion that therefore suffers usually is also more serious.
China's " power equipment ground connection designing technique rules " regulation: be laid in corrosion than high field grounding device, should take anti-corrosion measures such as hot tinning, pot galvanize according to corrosion property.In the case, because the hot tinning cost is very high, so China adopts pot galvanize, but to its anti-corrosion effect, following argumentation merits attention: the practical experience of (1), India shows that along with the reduction of coating protection effect, the corrosion of steel is quickened.Therefore, do not recommend zinc-plated basic anti-corrosion measure as the steel ground connector.(2), zinc coating can protect matrix metal in the early stage, but when the integrity of coating was damaged, then matrix metal (steel) will corrode with normal even paranormal speed.Though galvanized steel is the most frequently used coating form, coating is not effectively as unique anti-corrosion measure.(3), knownly zinc-platedly limited provide protection can only be provided to steel.The measure commonly used of long-term provide protection can be provided, and is galvanic protection---the protected mode of impressed current, sacrificial anode or the two associating.When selecting the galvanic protection mode, do not consider impressed current method usually, because when ground fault takes place, possibly have high potential gradient.Therefore, select for use sacrificial anode to be used for the corrosion prevention of steel ground net.(4), zinc coating is summed up as two kinds of effects usually to the provide protection of steel, promptly with electrochemistry (negative electrode) provide protection to steel of the insulation blocking effect of corrosive medium and zinc.The former depends on the solidity to corrosion of zinc to corrosive medium, and relevant with thickness of coating and quality; The latter depends on that then zinc coating is in a single day impaired, the galvanic corrosion of the protection domain of zinc and zinc self.
The purpose that the ground net in transmitting line, substation and power station only adopts galvanized steel can not reach protection against corrosion and increase the service life.
