medium voltage sf6 Call the police factory
A circuit breaker in which SF 6 under pressure gas is used to extinguish the arc is called SF 6 circuit breaker. SF 6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties which have proved its superiority over other arc quenching mediums such as oil or air. The SF 6 circuit breaker is mainly divided into three types.

Forms of ContactCircuit Breaker Trip SchemeCircuit Breaker Close SchemeSummaryBefore explaining what each device in the scheme does, understanding the different forms of auxiliary contact is necessary. Every breaker comes fitted with an auxiliary switch. It is mechanically linked to the breaker's trip close mechanism. Within the auxiliary switch case you can have either form 'a' contact (a.k.a. 52a per ANSI) or form 'b' (a.k.a. 52b). A form 'a' contact represents a Normally Open (N.O.) contact. Thus when the breaker is open, its 52a contacts are open. When the breaker is closed, the 52a contacts are closed. The 52a contact follows the status of the breaker. A form 'b' contact represents a Normally Closed (N.C.) contact. It operates exactly opposite of what an 'a' does. When the breaker is open, the 52b contacts are closed. When the breaker is closed, the 52b contacts are open. With the 52a contact in the trip circuit (as shown in the scheme above), once the breaker opens, this contact opens too. Now no matter what the relays do, the trip coil is isolated.

500kV Arc extinguishing Industry
24/8/2011Arc suppression is the reduction of sparks formed when current carrying contacts are separated. The spark is a luminous discharge of highly energized electrons and ions, and is an electric arc.The efficacy of an arc suppression solution for contact protection can be assessed, by comparing the arc intensity with the help of the following methods:
