ERVIST Group of companies together with its partners addressed the issue of protection
technique for safe operation of electrical equipment in hazardous areas by
producing cost-effective Russian solution utilizing Intrinsic Safety (IS) principle.
As it is known in the industry - Intrinsic Safety Barrier is the device that limits
the power (energy) that may be delivered from a safe area into a hazardous one.
This is an excellent solution – in this way explosions are prevented, not just
contained.
ABIZ – intrinsic safety
energy barriers
ABIZ barriers are
designed for operations in warning and alarm systems loops and in other
applications that require high current values of the intrinsically safe
circuit.
ABIZ Intrinsic safety barriers
constitute a single molded unit, potted and placed in a plastic (ABIZ-160) or
metal (ABIZ-1000) case. After contact with high voltage in intrinsically safe
circuits (coming from the control panel or IE to the barrier) the intrinsic
fuse if blowing - thus protecting the
circuit - disconnecting from hazardous voltage. Over current protection circuit
is provided by the Non-sparking tripling cell of active overcurrent protection.
SHSB-12/24 series of intrinsic
safety energy barriers
SHSB-12/24 intrinsic
safety energy barriers are designed for intrinsically safe circuit for fire and/or
alarm system. This system for
explosion-proof equipment group II according to GOST 30852.10 incorporates:
- contact fire and/or security sensors,
- contact sensors,
- push buttons with normally closed or open contacts,
- detectors, fed on a loop with level of intrinsic safety "ia"
This can
also be used for intrinsic safety for power cables, cables for
warning and alarm system for any electrical appliances and devices that are
compatible with parameters of IS barrier.
