Description
Technical field
The present invention relates to electronic scale industry, especially a kind of earthing device being used for stable electronic scale.
Background technology
Along with the development of science and technology, electronic vehicle weighing apparatus and the electronic track scale place of using gets more and more, the electronic scale such as electronic vehicle weighing apparatus and electronic track scale as the commercial weighing apparatus of one, to its measuring accuracy and stability requirement higher.Even weighing apparatus good again, if stability is out of joint, its measuring accuracy is not just known where to begin yet.
Influence amount is not the tested value of electronic scale, is but the amount affecting electronic scale indicating value.Influence amount comprises two classes: factor of influence and interference.Factor of influence is the influence amount that its value a kind of is within normal operating conditions that electronic scale specifies, as ambient temperature, humidity, air pressure and communication power supply voltage, DC power supply voltage, supply frequency etc.When actual motion, the factor of influence phenomenon that exceeds standard is also a lot.Interference is that its value a kind of is within the scope of regulation, but a kind of influence amount of the normal operating conditions specified beyond electronic scale, reflect the electronic scale influencing factor that weighing result may be subject in daily weighing process.Common interference has electrical fast transient (eft), static discharge, radio frequency electromagnetic field radiation, power frequency radiation etc.Environment residing for electronic scale, except there is the interference of electromagnetic field of various different frequency and amplitude, the large surface layer laying electronic scale may not be exactly desirable zero potential.As the earthing device of various electric equipment, building, the lightning rod ground stud of framework and the leakage etc. of underground cable, ground potential can be made to produce very big difference, and can change at any time.If therefore the grounding system of electronic scale arranges improper, not only do not have the effect of stable dynamic electronic rail balance work, cause grounding system to introduce interference on the contrary.But the electronic scale such as most of electronic vehicle weighing apparatus and electronic track scale being in running status does not all arrange grounding system of good performance, therefore when running into stronger interference, is just easy to the decline causing measuring accuracy and stability.How to design a kind of features simple structure, the earthing device of stable electronic scale of being used for of function admirable is an important problem.
Summary of the invention
For overcoming above the deficiencies in the prior art, the technical problem to be solved in the present invention is to provide that a kind of design is ingenious, and structure is simple, easy to use, dependable performance, stable, the excellent earthing device being used for stable electronic scale.
