FIELD: technology for ensuring safe conditions for using explosion-protected equipment in explosion-hazardous zones of industries of coal, oil, gas, chemistry and other branches.
SUBSTANCE: suggested spark-safe electric power device contains spark-safe power supply, communication line and inductive load with spark-suppressing bridges. Inductive load is made in form of at least two serially connected sections, in parallel to each of which a duplicated spark-protective bridges is connected.
EFFECT: increased spark safety power, transferred from electric power source to the load.
