Abstract
The invention relates to a grounding module material. The material is characterized by comprising the following raw materials by weight percent: 52% of graphite, 22% of conductive cement, 10% of bentonite, 3% of conductive powder, 6% of lime and 7% of water. The grounding module material has stronger binding property, good resistance-diminishing effect, low resistance, longer service time and better stability.
Description
Technical field
The present invention relates to a kind of earthing material, particularly a kind of earthing module material.
Background technology
Along with continuous development along with national economy, the quick raising of modernization level, under the guide that using IT to propel industrialization, the application of various information equipment, electronic computer, precision instrument, data networking equipment more and more widely, the harm of thunderbolt is also increasing.In this case; adopt the anti-Surge Protector of lightning protection with lightning current to release into the earth; become a kind of main flow; and earthing material also is widely used in the various grounding systems; the quality of ground connection effect is directly connected to the effect of whole lightning-protection system; therefore, ground connection has become a ring important in the lightning protection.And common earthing material such as angle steel etc., though can temporarily reach grounding requirement, but shortcomings such as its work progress is long, floor space is big, poor stability have displayed, and earthing module is exactly a kind of novel earthing material, and its floor space is little, stability is strong, the construction area area is little.
Existing earthing module material prescription mainly is made up of graphite, portland cement, inserts, lime, water etc., and have following defective: earthing module is frangible, and adhesiveness is not strong; Resistance reducing effect is not obvious; The resistance height, resistivity under the room temperature＜6 Ω m, power frequency earthing resistance: 12 Ω.
Summary of the invention
At present the deficiencies in the prior art, a kind of adhesiveness of the special proposition of patent of the present invention is stronger, and resistance reducing effect is good, the grounding electrode filling material that resistance is low.
The technical solution adopted for the present invention to solve the technical problems is as follows:
Earthing module material is characterized in that the weight proportion (percentage) of each raw material is: graphite 52%, electroconductive cement 22%, Peng Run soil 10%, conducting powder 3%, lime 6%, water 7%.
Beneficial effect of the present invention:
Adhesiveness is stronger, and resistance reducing effect is good, and resistance is low, and service time is longer, and is more stable.
Embodiment
Earthing module material is characterized in that the weight proportion (percentage) of each raw material is: graphite 52%, electroconductive cement 22%, Peng Run soil 10%, conducting powder 3%, lime 6%, water 7%.
Original earthing module material prescription is graphite 50%, portland cement 25%, inserts 10%, lime 8%, water 7%, now adds electroconductive cement, Peng Run soil, conducting powder, and the earthing module adhesiveness is strong, good toughness; Resistance reducing effect is obvious, resistivity under the room temperature＜3 Ω m, power frequency earthing resistance: 8 Ω.
Earthing module material includes stable conduction composition, metal passivation anticorrisive agent, water-loss reducer etc.It is embedded in underground, can closely contacts with soil, it is long-pending to enlarge the flow section that looses, and in the mild low resistance zone of change in resistance of underground formation, whole ground network ground resistance is significantly reduced.
