Abstract
Electrical switch designed for high voltage and/or current and surrounded by a housing (2) divided into a first part (2′) forming a first compartment for taking up at least one switching device (3) and an appurtenant actuator device (4), and a second part (2″) forming a second compartment for connecting of at least one phase. At least the first part (2′) of the housing (2) is pressure sealed encapsulated and filled with oil under pressure.
Claims14
Electrical switch comprising
- a housing (2) divided into a first section (2′) forming a first compartment for taking up at least one switching device (3) and an associated actuator device (4), and a second section (2″) forming a second compartment for connecting of at least one phase to the switching device (3),
- where at least the first section (2′) of the housing (2) is pressure sealed and filled with oil under a pressure of at least 10 bar,
- where the first section (2′) comprises at least one first compensator (5) for regulating the oil volume in the first section (2′) of the housing (2),
