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.
