The human body static electricity releasing alarm

1. The Human Body Static Electricity Releasing Alarm 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

"specification"

The human body static release alarm by the national explosion-proof

electrical product quality

supervision and Inspection Center (NCEX), in accordance with the

following criteria:

GB3836.1-2010 explosive atmospheres - part first: equipment -

General requirements

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 Human Body Static Electricity Releasing Alarm

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.

2.2 composition of the product

3 product features

1) ultra low power design, during normal usage and

no need to replace the battery

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 12.2.5.1.

2). Between the maximum ambient temperature between -40 ℃ ~+60 ℃.

3). Do not make changes to the product components, should be in the product

manufacturers together

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,

GB3836.12-2010

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

and maintenance

(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.

9.equipment maintenance

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.
