The human body static electricity releasing alarm
1. Product introduction:
The human body static electricity releasing alarm is suitable instrument for inflammable
and explosive and anti-static sites of human body electrostatic discharge.
It’s characterized by reasonable design of the human body
electrostatic discharge resistance, reasonable and effective control of human
body electrostatic discharge,
extend the human body electrostatic discharge time, reducing the instant
the human body electrostatic
discharge energy, can make human body electrostatic safety release.
At the same time can detect body
and the electrostatic touch the ball contact is reliable,
acousto-opticalarm static elimination is finished.
The human body static electricity releasing alarm
design reference below the national standard:
GB12158-2006 " Prevent electrostatic accidents general guidelines"
GB5074-2002 " Code for design of oil depot "
The provisions of article 14.3.13: because people wear synthetic fabrics
clothes is extremely common,
artificial fabric is easy to produce static electricity,
tend to accumulate in the body. For anti-static may
produce sparks,need to enter the pump house, light oil tank top,
light operation platform,
as well as the device of explosion hazardous areas at the escalator
or arranged at the entrance of
eliminating static electricity of human body. The static elimination
device is made of metal tube handrail,
before entering into these places should touch the human body
to eliminate static electricity.
Grounding design of electrostatic petrochemical SH3097-2000
The human body static release alarm by the national explosion-proof
electrical product quality
supervision and Inspection Center (NCEX), in accordance with the
GB3836.1-2010 explosive atmospheres - part first: equipment -
GB3836.4-2010 explosive environment of fourth parts:
the intrinsic safety type"I" protection equipment
Product explosion-proof symbol is ExiaIICT4 Gb.
2. Working principle and composition of the product:
2.1 Working principle
At present, some flammable and explosive dangerous places still use the
metal conductor is directly grounded discharge
method to eliminate static electricity on human body, although this approach
can eliminate the static electricity on human body,
but the way the use of conductor between the discharge form release static
charge, the release of small resistance, electrostatic
discharge time is short, the moment release energy, which leads to the necessity
and the possibility of human electric shock or
fire explosion accidents.
The human body static electricity releasing alarm for the current human static
removal methods of the lack of reasonable human
body electrostatic discharge resistance, prolong the human body electrostatic
discharge time, reduce the human body electrostatic
release energy, effectively avoid the occurrence of human body electrostatic
electric shock and fire and explosion accident phenomenon.

7 how to use product:
8 product installation notes:
1). Static release alarm installation must be in accordance with the
GB836.15-2010 explosive environment of fifteenth parts: the risk of
the electrical installation
(other than mines) "the requirements of article 184.108.40.206.
2). Between the maximum ambient temperature between -40 ℃ ~+60 ℃.
3). Do not make changes to the product components, should be in the product
to solve the faults occurred in the operation, in order to prevent the damage phenomenon.
4) installation, and maintenance of product shall comply with the product manual,
explosive atmospheres - Part thirteenth: electrical apparatus for explosive gas
atmospheres of maintenance,
GB3836.15-2010explosive atmospheres - Part fifteenth: hazardous area electrical
installation(other than mines),
GB3836.16-2010 explosive atmospheres - Part sixteenth:electrical equipment inspection
(except mine) and the relevant provisions of the GB50257-1996 "installation of the
electrical installations of explosion and fire hazardous electrical equipment construction
and acceptance specification".
5) products can not work normally, need to replace the explosion-proof touch ball.
1). Keep the equipment clean, regular cleaning of the explosion-proof touchdust,
ball on the oil, prevent the reduction
of sensitivity explosion-proof touchball.
2). Regular inspection and maintenance of equipment, check the grounding
wire grounding bolt and other
parts is loose, so as not to cause bad contact.
