The energy discharge static electricity is allowed to take energy, mile area flashover channel length l, the corresponding length bit time period,Sensitivity is defined as the object of the protection to the зажигающему exposed to static.
for gas and form flammable/explosive vapor-air mixture is permitted to take:
, (2)
Where so - safe pilot clearance (БЭМЗ), as measured by the GOST 1.12.011 .
For пылевоздушных mixtures may be used length of the l, installed on a method for determining the minimum ignition energy in GOST 12.1.044 .
is already at the level of project documentation can be given constructive options, so that technological apparatus will meet the challenges of ensuring ЭСИБ.For existing units can be a compliance calculation their requirements ЭСИБ and to identify what, if any, changes should be made in their design. Consider that the machine meets the requirements ЭСИБ,If radius (l) (m) the scope, for instance on the cavity, corresponds to the lowest energy ignition switch located in the grief of oil whose mixture. When values minimum ignition energy W (j); mixtures,In which an oxidant is air, from 10-3 to 10-1 J. the corresponding linear size can be defined in table 11.
