Body, the spherical of stainless steel, the release electrostatic by way of direct body contact.When static electricity on human body's pressure value is high, due to
The resistance value of Releasing loop is minimum, and it is larger to easily lead to discharge current, and then corona and spark discharge easily occurs, i.e., so-called " to beat
Hand " phenomenon, also have cause fire, explosion accident possibility.The spherical surface resistivity of sub- conductive material be in 1 ×
The Ω of 107 Ω~1 × 109, release current is in uA grades when human body release electrostatic, and charge transfer quantity is less than 0.1uC, is not in quiet
Discharge of electricity phenomenon, has reached essential safe type.The touch sphere top of this Asia conductive material uses capacitance touch inductor,
Capacitance touch inductor can be prevented from occurring mechanical friction in inflammable and explosive environment, be hit instead of traditional mechanical switch
Spark phenomenon.But it as long as this capacitance touch inductor capacitance knots modification is more than setting threshold values, is defaulted as human hand and touches
The explosion-proof touch body of sub- conductor has been touched, Electro-static Driven Comb is being carried out.When wearing gloves or the big material of other insulating properties on human hand
When object, human hand is placed on explosion-proof touch body top, although human hand is without the explosion-proof touch body of the practical sub- conductor of contact, the electricity of change
Capacitance can also be more than setting threshold values.Since gloves are insulators, the electrostatic on human body connects not over the explosion-proof touch body-of sub- conductor
This primary Ioops of ground wire-grounded screen are discharged into the earth, but are persisted on human body.But because of the change of capacitance, when
When touching release time of the time more than the setting of master controller internal program, human body release electrostatic is prompted yet by voice or indicator light
It finishes.Therefore, being released effectively for static electricity on human body is not ensured that, especially in enterprises such as petrochemical industries, operator is in work
Protective gloves is equipped in work, after this static electricity on human body's monitor release electrostatic without really monitoring release electrostatic, people
Body electrostatic still has.It enters back into and static sparking easily occurs when danger zone operates, explosive gas around ignition and blasting, band
Great security risk is carried out.
