Electrostatic release device

1.The human body electrostatic release alarm product introduction

The human body static electricity release alarm is an instrument suitable for human body static electricity release in flammable, explosive and anti-static places. It is characterized by the design of reasonable human static electricity release resistance, reasonable and effective control of human static electricity release, prolong the human static electricity release time, reduce the instantaneous human static electricity release energy, can make the human static electricity safe release. At the same time, it can detect whether the contact between the human body and the electrostatic touch ball is reliable, and the audible and visual alarm prompts whether the electrostatic elimination is complete.

Human body static release data design refer to the following national standards:

GB12158-2006 "General Guidelines for the Prevention of Electrostatic Accidents"

GB50074-2002 "Design Code for Petroleum Storage"

Article 14.3.13: Since it is very common for people to wear artificial fabrics, artificial fabrics are prone to generate static electricity and accumulate on the human body. In order to prevent sparks that may be generated by static electricity, devices to eliminate static electricity of the human body should be installed on the operation platform entering the pump room, the roof of the light oil tank, the operation platform of the light oil working area, and the escalator or the entrance of the explosion danger area. The electrostatic removal device refers to a handrail made of metal tubes, which should be touched by the human body to eliminate static electricity before entering these places.

SH3097-2000 "Petrochemical electrostatic grounding design Code"

The human body electrostatic discharge basket has been approved by the National Explosion-proof Electrical Products Quality Supervision and Inspection Center (NCEX) and meets the following standards:

GB3836.1-2010 Explosive atmospheres - Part 1: General requirements for equipment

GB3836.4-2010 Explosive atmospheres - Part 4: Equipment protected by this M-safety "i"

The explosion-proof mark of the product is ExibIICT6Gb.
