Explosion human electrostatic discharge device body static eliminator direct special sound and light alarm

Electrostatic discharge alarm is for flammable, explosive and anti-static properties of human electrostatic discharge instrumentation. Characterized by rational design of human electrostatic discharge resistance, reasonable and effective control of human electrostatic discharge and prolong human body electrostatic discharge time, reduce instant human electrostatic discharge energy, enabling the body to release static electricity security. At the same time the human body can be detected with the electrostatic touch the ball contact is reliable, sound and light alarm static elimination is completed. Human electrostatic discharge alarm design reference to the following national standards: GB12158-2006 "General Guidelines to prevent static electricity accident" GB5074-2002 "Oil Depot Design Specifications" section 14.3.13 states: Because people wearing clothes very common artificial fabric, synthetic fabric pole easy to produce static electricity, they tend to accumulate in the human body. To prevent static electricity sparks that might arise, we need to enter the pump room, light tank top, light oil on the platform work area, as well as explosive or hazardous areas, etc. of the escalator at the entrance to set the device to eliminate the human body static electricity. This refers to the elimination of static devices made of metal pipe handrails, before entering such places should touch the armrest body to eliminate the human body static electricity. SH3097-2000 "Petrochemical static grounding design specifications" human electrostatic discharge alarm proof electrical products by the State Quality Supervision and Inspection Center (NCEX), meets the following standards: GB3836.1-2010 Explosive atmospheres - Part 1: General requirements GB3836.4 equipment -2010 explosive atmospheres - Part 4: the intrinsic safety "i" protection equipment product proof mark ExiaIICT4 Gb. 2, the product works and works composed 2.1 Currently, some of flammable and explosive places still grounded metal conductors direct way to eliminate the discharge body static, although this approach can eliminate the human body static electricity, however, this method using a discharge between the conductors released in the form of electrostatic charge, the release resistance, electrostatic discharge time is short, instantaneous release of energy, causing the body electric shock or fire explosion of possibility and necessity. Human electrostatic discharge alarm to make up for shortcomings of current body static guide except the way of rational human electrostatic discharge resistance and prolong human electrostatic discharge time, reduce the body's electrostatic instantaneous release of energy, and effectively avoid the fire and explosion accidents and human electrostatic shock phenomenon . During the product composition without replacing 2.2 3. Product Features 1. Ultra-low-power design, the normal battery 2. touch-sensitive, no mechanical moving parts 3.
