Abstract
The utility model provides a system preventing static electricity from grounding. The system comprises a grounding grid buried underground and composed of galvanized steel strap, and a plurality of grounding terminals arranged on the ground. The grounding terminals comprise a resistor and a voltage dependent resistor which are connected in series. After the resistor and the voltage dependent resistor are connected in series, one end of the grounding terminals is connected with the grounding grid composed of the galvanized steel strap, and the other end of the grounding terminals is connected with another galvanized steel strap. Through the system preventing the static electricity from grounding formed by the grounding terminals arranged on the ground and the grounding grid connected with the grounding terminals and buried underground, the generated static electricity can be effectively released, and damage to human bodies or equipment caused by the static electricity is avoided.
Description
Technical field
The utility model relates to a kind of anti-static system, relates in particular to a kind of anti-static grounding system.
Background technology
Static can be described as ubiquitous, on our body and on every side all with very high electrostatic potential, several kilovolts even several ten thousand volts, may know from experience at ordinary times less than, the carpet static of chemical fibre approximately is 35000 volts but the people passes by, the static of plastics specification browsed approximately is 7000 volts, and for some responsive instruments, this voltage may be fatal harm.
Especially the device rooms of special type protection technology is arranged being provided with the machine room of communication equipment, computer room etc., to electrostatic defending, electrostatic safety has specific (special) requirements, under identical environmental condition, not changing on the basis that reduces machine room earth resistance rate and system resistance, be badly in need of developing the device systems that a cover can effectively prevent static.
The utility model content
The utility model provides a kind of anti-static grounding system, is used for solving prior art because the static that produces can't effectively discharge causing technical problem that human body or equipment are worked the mischief.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
A kind of anti-static grounding system, comprise and bury in the underground ground network that is formed by zinc-coated flat steel sheet and be arranged on ground a plurality of earth terminal, described earth terminal comprises resistance and the piezo-resistance of series connection, an end was connected with the ground network that is comprised of zinc-coated flat steel sheet after resistance was connected with piezo-resistance, and the other end is connected with another zinc-coated flat steel sheet.
Further, described earth terminal is arranged in the mounting box.
Further, described mounting box is fixed on the bracing frame of vertical ground setting.
The anti-static grounding system that the utility model provides, by being arranged on ground earth terminal and the anti-static grounding system that consists of in the ground network on ground of burying that is connected with described earth terminal, can effectively with the static release electrostatic that produces, avoid static that human body or equipment are worked the mischief.
Description of drawings
Fig. 1 is the plan structure schematic diagram of the utility model anti-static grounding system;
Fig. 2 is the generalized section of this utility model anti-static grounding system.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme in the utility model is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Please consult simultaneously accompanying drawing 1 and accompanying drawing 2, Fig. 1 is the plan structure schematic diagram of the utility model anti-static grounding system; Fig. 2 is the generalized section of this utility model anti-static grounding system, and as shown in Figure 1, anti-static grounding of the present utility model system forms by burying in the underground ground network 1 that is comprised of zinc-coated flat steel sheet and being arranged on ground a plurality of earth terminal 2.As shown in Figure 2; wherein; described earth terminal 2 is in series be used to preventing that electrostatic potential is excessive and the resistance 21 and the piezo-resistance 22 that shield; described resistance 21 are connected with piezo-resistance the circuit one end that is composed in series be connected by the ground network 1 that is formed by zinc-coated flat steel sheet of burying in underground, an other end is connected with another zinc-coated flat steel sheet 3.
Further, on the basis of above-mentioned anti-static grounding system, do not damaged by external force by protecting earth terminal 2 of the present utility model, described earth terminal 2 is arranged in the mounting box 4.
Further, on the basis of above-mentioned anti-static grounding system, described mounting box 4 is fixed on the bracing frame 5 that a vertical ground arranges.
The utility model is achieved by the following technical solutions:
Smearing screed-coat, is 0.4-0.5 at one water cement ratio of screed-coat external coating by weight: 1 plain-water slurry, after screed-coat wipes, carry out floating screed after the ash cake knot is hard.
Low temperature or teletostage maintenance 3-5 days treat that intensity reaches 1.2MPG, can descend together construction.Earth connection lays, and earthing material is selected zinc-plated band iron.Holistic approach with earth connection in a side of predetermined ground connection along the ground long axis direction, 30cm place apart from the wall place imbeds in the screed-coat, and the dividing strip of upper surface concora crush on earth connection of the upper level of earth connection and screed-coat should separate with insulation film or insulating thin and earth connection.The length of the above part of earth connection stand-down is determined according to the distance of grounding system.After earth connection is completed, should be with the mortar wiped clean that is attached on the earth connection, area surpasses 500m
2Workplace, earth connection should have two.
Laying of earth terminal laid earth terminal by designing requirement, adds glue with plain cement and is fixed on the screed-coat, and for preventing that earth terminal from becoming flexible or displacement, earth terminal must be built securely, be vibrated and maintenance, and should strengthen finished product protection.
The utility model technology, significantly reduce project cost has improved machine room available height space simultaneously, and long service life, and is survivable.
It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
