The RV44 load-break switch consists of an epoxy housing, containing fixed and movable contacts.The switch is filled with SF6 gas (sulphur hexafluoride) and is sealed for life. The special characteristics of the SF6 gas guarantee a perfectly insulating and arc-extinguishing function within the housing.As a result of the ideal switching speed of the switch/drive-mechanism combination, the load-break switch produces very short arc times. The patented switching principle combines a maximum gas revolving effect with a precise finish of the electrical contacts. This guarantees excellent dielectrical features and minimal contact erosion.The load-break switch is a twin position switch that connects or interrupts the voltage between the high voltage cables and the bus bar. The position of the load-break switch is clearly indicated on the single line diagram.Depending on the version, the load-break switch is operated manually or electrically.With a history dating back over 38 years, Mevoco nv has specialised, in particular, in the design and the production of medium voltage switches from 10 to 36 kV.
The arc-killer extinguishes an internal arc by directing it to a metal earthed short circuit. The arc is extinguished in less than 50 ms.
