- Abstract
The paperwork presents aspects regarding a capacitive model for the galvanic elements used in the apparatus intended for use in explosive atmospheres. In the first part was presented the explosion risk. The explosion risk, involved by the presence of the equipment in areas characterized by the presence of flammable substances is manifested through two sources of risk. The spark ignition could occur due to the electrical equipment, mechanical impact and electrostatic discharges. Also, flammable substances could be ignited by hot surfaces. Additionally, was also included, a short presentation of intrinsic safety type of protection. In the second part was exposed the proposed theoretical model of galvanic elements. The third part of the paper was allocated to the presentation of the test stand, to the results obtained from the tests and discussion. Also, with this occasion it was analyzed the correspondence of the proposed theoretical model with experimental test results. From the test results was obtain the value of equivalent electrical capacity of the galvanic elements which is visible at the first part of discharge. This achievement facilitates the assessment of ignition risk due to capacitive circuit.
