Description
Technical field
The utility model strengthens that the corrosion-resistant earthing device relates to is a kind ofly can be applied to heavy corrosion industries such as oil, petrochemical industry, electric power, is the anti-corrosion grounding device of the antiseptic effect that strengthens the lightning protection device.
Background technology
Though earthing device shared ratio in the whole investment of project of transmitting and converting electricity, important buildings is very little; but the accident that it causes is extremely surprising; really be " electrical network killer "; its secondary device in can very fast destruction electrical network; equipment such as picture direct current, protection, communication are followed accidents caused expansion, and what have causes device damage, initiation fire; what have causes power plant, transformer station's full cut-off, have in addition develop into serious systematic failures.For example, Sichuan power plant once because of the discharge of transformer neutral point earth connection heavy corrosion place, introduced master-control room with high potential, cause many places puncture, short circuit, total fuse melting can not excise fault automatically, causes No. 2 main transformers, No. 2 engine fires, No. 3, No. 4 generator damages power cut of whole factory.
The fast development of modern microelectric technique, also more and more higher to the ground connection environmental requirement, there is a very little stream just to gush and makes device damage, people also progressively improve the attention degree of grounding system, can ground connection is done get well and badly be directly connected to equipment normally move, and whether the big problem of potential safety hazard is arranged.
Because there is etching problem in the metal material as ground connection, and is bigger to the influence of earth resistance, is a big hidden danger, this problem is perplexing the user always.Generally in telecommunication system, early stage earth mat was just transformed once in per 4 years again, and often will transform again one or two years in saline and alkaline area.Some large-scale 500kV substation grounding device only puts into operation about 10 years because of corrosion, and just throwing huge fund has changed earth mat again.Statistics shows that the earthing device corrosion is the one of the main reasons of most accidents.For this reason, domestic a lot of units are all carrying out the research of this respect, and have proposed many anticorrosive measures.
In the existing lightning protection engineering, the anti-corrosion measure of earthing device has:
1) there are employing copper cash (band), copper covered steel (to contain electro-coppering etc., continuous casting copper) lightning protection line, though decay resistance has been improved at general medium soil environment, but still can not satisfy the environment that some specific organic media corrodes, because in a single day this product is shaped, just can't changes the corrosive power of the medium of anti-particular etch the on its surface, and use copper to place into the soil in a large number, if be not inconsistent, then will use the soil environment in zone to be polluted with the background tenor of native soil environment.
2) have and adopt the galvanized steel material to be aided with a large amount of resistance reducing agents to reduce earth resistance, but at complicated climatic environment (high mountain, during construction severe cold etc.), substantially can't reach construction requirement, the reliability of electric welded contact can not get ensureing at all, simultaneously, resistance reducing agent also may form corrupt erosion to the ground connection steel material, and pad also can't obtain etch-proof assurance.As the described method of ZL03214327.3 only operation instruction a kind of bentonite resistance reducing agent, the sectional area that can only equivalence increases earth electrode, the various resistance reducing agents that badly can't make that can't change because of execution conditions wrap up earth electrode fully and fully, because of wanting fully and abundant parcel earth electrode, and be unpractical to the control method that work progress is designed various complexity, this has been common recognition in the industry.The resistance reducing agent scene of wanting is configured as thick flocculence (manual process can't guarantee that various uniform ingredients cooperate) simultaneously, to be metal contact and be solid with nonmetallic for resistance reducing agent and earth electrode--and the combination of liquid phase, contact resistance therebetween are that one of ground connection field does not have a difficult problem of separating greatly always.
3) have that to adopt earthing module or ionic earth electrode, this series products all be to change and produce not only valency height through resistance reducing agent, and all be that earth electrode is developed in depth and breadth, construction cost increases substantially.And this series products all should be with metal material as basic framework, must be the main framing that main material connects and composes electric welding system with the base metal material, the anticorrosive property at its link place, conductivity, stability all are limited by site operation personnel's construction technical ability and quality, and destabilizing factor is very big.The problem that all ionic materials all have corrosion and contact resistance to guarantee to the metal that constitutes its main material.Simultaneously because of adding the ion major part contain Nacl, and can change the native soil composition, easily cause environmental pollution.Main is at places such as equipotential connections, just can't be abutted against ground module and ion grounding electrode carry out.So use the limitation of earthing module or ionic earth electrode very big, corrosion-resistant problem that can't the radical change earthing device.
4) original simple use galvanized steel section bar is arranged as the lightning protection device, this is in the field of business to be considered to, is not suitable for above-mentioned each heavy corrosion field, only limitation be used in requirement extremely general with the lightning protection system of common buildings in.The stability of its junction contact that continues, reliability all are subject to the quality of the construction situation in later stage in addition, can't guarantee the stability of electral junction from the source.
Summary of the invention
The utility model purpose is the weak point at existing earthing device aseptic technic and construction technique, a kind of reinforcement corrosion-resistant earthing device is provided, has the anti-corrosion type of reinforcement lightning protection line, strengthen the anti-corrosion type earth electrode, strengthen the components of a system such as anti-corrosion type conductor splice spare, equipment connector.
