A gas circuit breaker is a type of electrical protection device designed to interrupt the flow of current in an electrical circuit in the event of an abnormal condition, such as an overload or short circuit. Unlike conventional circuit breakers that use mechanical switches, gas circuit breakers use a gaseous medium to extinguish the electric arc that forms when the current is interrupted.
The basic operating principle of a gas circuit breaker involves the use of an insulating gas, such as sulfur hexafluoride (SF6), which is introduced into the equipment. When a fault occurs in the circuit, generating an electric arc, the gas is released to extinguish this arc. This is done to prevent damage to the circuit breaker components and ensure safe current interruption.
The HD4 medium voltage circuit
breakers use SF6 gas technology
to protect your assets, ideal for
all applications where a
smooth switching is an advantage. HD4s are the best answer for
most application fields
such as power distribution,
cable protection, overhead
lines, transformers and
substations. HD4 medium voltage circuit
breakers use sulfur hexafluoride
gas (SF6) to extinguish the
electric arc and as an insulating
medium. The breaking of SF6 gas occurs
without any arc cutting and
without generating
overvoltages. These
characteristics ensure long
electrical life of the circuit breaker
and limited dynamic, dielectric and thermal stresses in the
installation. The circuit breaker poles, which
make up the breaking part, are
systems with lifetime sealed pressure (IEC 62271-100 standards)
and are maintenance-free.
The mechanical type ESH
operating mechanism, with
stored energy has free release
and allows opening and closing
operations independently of the
operator's actions. The operating mechanism and
the poles are fixed to the metal
frame which also serves as
support for the kinetics to
operate the moving contacts.
