After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF6 gas is electronegativeand has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high pressure flow of sulfur hexafluoride gas, and an arc i…See more on en.wikipedia.orgEstimated Reading Time: 12 minsSulfur Wikipedia en.wikipedia.org/wiki/SulfurSulfur (in British English: sulphur) is a chemical element with the symbol S and atomic number 16.

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 5…See more on peguruEstimated Reading Time: 7 minsFrom 72.5 kV up to 800 kV High Voltage Circuit Breakers assets.siemens energy/siemens/assets/api/uuid:d375c070 e8f...PDF filegas compression creates a gas flow through the contact cylinder (5) and the nozzle (2) to the arcing contact, extin guishing the arc. rod (4), pin (2), control lever (3) (circuit breaker opening movement).
