L7-JDQ Human Static Discharge Alarm Intelligent Sound and Light Alarm 1. Product Introduction& The L7-JDQ human static discharge alarm is an instrument suitable for the discharge of human static electricity caused by flammable, explosive, and anti surface electric fields. Its characteristic lies in the design of a reasonable human body electrostatic discharge resistor, the reasonable and effective control of human body electrostatic discharge, the extension of human body electrostatic discharge time, the reduction of instantaneous human body electrostatic discharge energy, and the safe release of human body electrostatic discharge. At the same time, it can detect whether the contact between the human body and the electrostatic touch ball is reliable, and sound and light alarms indicate whether the electrostatic elimination is complete. The design of human static electricity release alarm refers to the following national standards: GB12158-2006 "General Guidelines for the Prevention of Static Electricity Accidents" GB50074-2002 "Design Specification for Petroleum depots" 2. Product working principle and composition 2.1 Working principle; At present, some flammable and explosive hazardous areas still use metal conductors directly grounded for discharge to eliminate human static electricity. Although this method can eliminate human static electricity, it releases static electricity in the form of discharge between conductors, with low release resistance, short static discharge time, and large instantaneous energy release, which may lead to the possibility and inevitability of human electric shock or fire and explosion accidents. The human body electrostatic discharge alarm compensates for the shortcomings of the current methods of human body electrostatic discharge. A reasonable human body electrostatic discharge resistance prolongs the time of human body electrostatic discharge, reduces the instantaneous energy released by human body electrostatic discharge, and effectively avoids the occurrence of fire and explosion accidents and the occurrence of electric shock to the human body. At the same time, the human body static electricity release alarm has a touch sensitive sensing system that ensures reliable contact between the human body and the touch ball. There are no moving mechanical components, and the sound and light alarm prompts whether the static electricity has been completely released.
