The life, nowhere is not in electrostatic it may be said in production, when notting have, be absent, cast from raise one's hand sufficient a friction of dress, flow to dry airy, it is the end of the Qing Ping of electrostatic generation. If the condition is appropriate, inchoative a few bend over, reach the limit at hundreds of go up kilovolt, the instant also can come true. These cause great menace to the electrostatic and sensitive circuit such as CMOS, more the harm that leakage of electricity of equipment of needless to say causes, all without exception of reason electron industry will be electrostatic regard as archenemy, use up everything outside the door of the ark of effort general.
Electrostatic it is opposite move electric ” at “ , namely the charge of going from place to place in conductor, be usually stagnant charge. Much by dielectric grind each other between the object or dry air and insulant grind generation. When it energy accumulates certain level, prevent hinder when the dielectric that it counteracts also is not held back again, produce acuteness discharge namely, namely electrostatic discharge (ESD) , at this moment highest voltage can be amounted to thousands of and even tens of thousands of bend over. Certainly will is caused to electrostatic and sensitive component damage.
Thunder is the water in air current and cloud layer grinds the high pressure of generation is electrostatic discharge and form, electrified cloud layer passes high pressure near the building when, can counteract; of one share charge to be measured when the charge in cloud layer by the effect of " of " point discharge of lightning rod too big, or cloud layer shift is too rapid and when having not enough time to be counteracted entirely, will pass lightning rod acuteness discharge forms be struck by lightning. Below these two kinds of circumstances, especially when be struck by lightning, whole structure reachs around floor is electrified, the harm of be struck by lightning basically is to attack thunder and thunder electric induction continuously. " is in in the building as a result of the person equipotential " condition, fall on the high tension line like bird same, won't get commonly so be struck by lightning. Dan Lei electric induction (extrahigh voltage static electric induction and strong report magnetic induction) can cause to electrostatic and sensitive parts of an apparatus damage.
Equipment leakage of electricity, the badge small leakage of electricity that won't cause harm getting an electric shock to the person especially is not belonged to electrostatic. Although most circumstance issues people not to feel almost, but as a result of its catholicity (more or less do any wiring always have some of leakage of electricity) the characteristic with tall internal resistance, generation is highest and approximate at power source voltage (100~400V) , the aiguille report pulse with very short time, still enough causes electric overload to electrostatic and sensitive parts of an apparatus (EOS) is damaged. Also be electrostatic so defend a very important facet in the system.
