ET-PSA-D human electrostatic discharge alarm (static voltage in real-time display of human static eliminator) 1 Introduction ET-PSA-D human electrostatic discharge alarm is for flammable, explosive and anti-static properties of the human body electrostatic discharge instruments. 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. While detection of human electrostatic discharge alarm is properly grounded, human and explosion-proof touch the ball contact is reliable, the display shows the body of any static voltage static voltage value, sound and light alarm static voltage exceeds the set alarm voltage. ET-PSA-D human electrostatic discharge alarm design reference to the following national standards: GB12158-2006 "General Guidelines to prevent static electricity accident" B50074-2002 "Oil Depot Design Specifications" section 14.3.13 states: Because people wearing synthetic fabric garments extremely universal, artificial fabric easy to produce static electricity, tend to accumulate in the human body. To prevent static electricity sparks that may arise, the need for entering the light oil pumping station, 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" ET-PSA-D 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: Equipment General requirements GB3836.4-2010 Explosive atmospheres - Part 4: the intrinsic safety "i" protection equipment product proof mark ExiaIICT4 Gb. 2 the working principle and composition 2.1 works Currently, some flammable, explosive dangerous places still use metal conductor directly to ground discharge way to eliminate the human body static electricity, although this approach can eliminate the human body static electricity, however, this method using discharge between conductors form release 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. ET-PSA-D human electrostatic discharge alarms make up the current body static guide except the way of lack of rational human electrostatic discharge resistance, extending the human electrostatic discharge time, reduces the body of electrostatic energy released instantaneously, effectively avoid fire and explosion accidents occurrence and bodily electric shock phenomenon. In touch instant, can detect human body static voltage carried displayed in the static voltage monitor, more visually see changes in the course of human body electrostatic discharge static voltage values. Meanwhile, ET-PSA-D human electrostatic discharge alarm touch-sensitive body and the ball touches the touch-proof and reliable, no moving mechanical parts, sound and light alarm body static voltage exceeds the alarm according to the detected static voltage. Without replacement during the 2.2 product composition buzzer proof touch the ball Status Indicator static voltage monitor signs on pole ground wire 3 Product Features 1. Ultra-low-power design, normal use. 2. The touch-sensitive, no mechanical moving parts. 3. The overall epoxy resin encapsulated, corrosion, water and moisture. The explosion-proof touch the ball, safe electrostatic discharge, human contact does not produce a sense of shock. 5. The sound and light alarm touch the ball body and the explosion in contact reliability and static voltage exceeds the set range. 6. The ground wire independent testing, test ground resistance <55Ω, ensure reliable grounding. 7. The human body static voltage is detected by sensors, not directly into the internal circuit to ensure plant safety. 8. OLED display static voltage monitor directly detected static voltage can be more visually observed electrostatic discharge 9. The left hand touch the ball after the voltage detection sustained 5S entering hibernation, reduce system power consumption. 10. Ground Fault Status alarm for 1 minute into hibernation, wake up immediately after touch-proof touch the ball, testing ground state again. 4 Product Specifications 4.1 Electrical parameters 1. Power supply: High-performance built-in lithium battery 2. Sleep current: <1mA 3. Working current: <5mA 4. Working temperature: -40 ℃ ~ 60 ℃ 5. Response time: <1s 6. Grounding resistance: <55Ω 7. proof grade: ExiaIICT4 Gb 8. Hydrostatic voltage: ± 10KV 9. Alarm: sound and light alarm 10. Cable length: 3m straight cable 11. PU alarm voltage: 100V product use hibernation when the body and Explosion touch the ball when there is no contact, human electrostatic discharge alarm dormant, static voltage monitor does not display, no alarm buzzer alarm status when the body is in contact with reliable explosion-proof touch the ball, the body is sensitive to electrostatic discharge alarm human body, and it is detected When the body reaches the alarm voltage charged into the alarm state, static voltage display static voltage value, the buzzer alarm, the red light flashes. Electrostatic being released, do not leave! Normal state when the body is in contact with reliable explosion-proof touch the ball, the body is sensitive to electrostatic discharge alarm the body, and when it detects the body charged less than the alarm voltage, into the normal state, static voltage display static voltage, beeper does not sound, the green light flashes . You can touch the ball leaving the hand, 5 seconds into hibernation. Electrostatic discharge is completed, you can enter dangerous workplaces. Grounding alarm status when the ground line is disconnected, the alarm is in human electrostatic discharge grounding alarm state, does not detect static voltage static voltage monitor does not display, buzzer alarm, flashing yellow light. Grounding alarm for 1 minute, into hibernation, when touch-proof touch the ball again, the system continues to detect ground is normally wake. 5 Product Installation Precautions 1.
