Two, background technology

The world today has entered cyberage, and it is to guarantee the person, structures and important measures electric, the microelectronic device safe operation that earthing device is set.Practice shows that traditional earth electrode exists the contradiction of the positive negative effect coexistence of falling resistance and corrosion, and the earth work personnel are very deeply concerned to persistence and reliability that the resistance facility falls in ground connection.The physical dimension that the employing of high resistivity soil ground connection is strengthened metal (iron and steel or copper) earth electrode as far back as the fifties people reduces earth resistance, though this method can reduce the resistance of earth electrode, but expend a large amount of high-test metal materials, the cost height, sometimes also be difficult to realize its its intended purposes, get a desired effect.Around the metal earth electrode, adopted industrial residue or charcoal to improve resistance reducing effect afterwards with the way of salt.This method is because electrolytical existence has obvious resistance reducing effect at the initial stage that device comes into operation, but brings the heavy corrosion of metal earth electrode simultaneously, and seasonal in addition level of ground water is risen and fallen and caused the loss of electrolyte, thereby makes it lose the resistance effect of falling.Begin to turn to the research of chemical grounded resistance reducing agent afterwards the seventies people, though various in style, its performance is similar, all is with by Cl basically ^-, SO ^-2 ₄, NO ^- ₃The highly basic strong acid salt that ion and highly basic metal constitute is a conductive materials, again by being mixed and made into urine aldehyde, acrylamide or silicate cement condensate.Thisly to saving steel, reduce cost, improve the loss etc. of conductive materials and played positive role, but corrosion still exists by enlarging the method for earth electrode physical dimension.It is the physics resistance reducing agent of conductive materials that the nineties begins to adopt with the carbon material, and the use of physics resistance reducing agent causes chemical resistance-reducing agent to be given up the throne.But the common ground of resistance reducing agent all is a powder, not only packs, transport inconvenience, the appearance of need cutting the earth at the construction field (site) during use, and metering adds water and sizes mixing and pour into earth electrode again, brings constructional difficulties to the user, especially constructs more difficult in high mountain and anhydrous area.In order to overcome the inconvenience in use of powdery resistance reducing agent, people have carried out again further seeking, and have obtained some positive achievements.

The patent No. is that the Chinese utility model patent of ZL94230002.5 discloses a kind of low resistance earthing module, and this patented technology has played positive role to the resistance reducing agent inconvenience in use that overcomes conventional art.The low resistance earthing module of this patent disclosure is formed by pole piece and Fei Jin electrolysis gelling thing casting solidification.Because its metal pole piece integral body as electrode is positioned at and falls resistance layer, contact with electrolyte ion integral body as conductive materials, seriously corroded, therefore do not solve the contradictory problems of falling resistance and corrosion coexistence of the earth electrode existence of conventional art, promptly the contradiction that hinders with corroding of falling of earth electrode still exists.

Three, summary of the invention

At the deficiency of prior art, the purpose of this utility model be the design a kind of easy to use, anticorrosion with fall the resistance have concurrently and the reliable compound earthing module of technology.

Can realize the utility model above-mentioned purpose earthing module, its technical scheme is as follows:
