The invention relates to the control of an electric switching apparatus that includes two switches such as a busbar sectionalising switch and an earthing switch.
The invention relates to switchgear (100) which has at least one circuit breaker or switch (107), an earthing switch (113) and a disconnector (105).
The switchgear is characterized in that the earthing switch (113) is coupled to a first straight drive shaft (205) and the disconnector is coupled to a second straight drive shaft (207).
Each year, VEI obtains numerous patents for its innovations, one of which being its three-function device integrating a circuit breaker, a disconnector and earthing switch.
Furthermore, the invention relates to a method for switching an air-insulated grounding switch, wherein no arc owing to a voltage flashover is produced on the air-insulated grounding switch.
The invention relates to an electrical switching device having a first interrupter unit for interrupting and connecting an electrical line, in particular an air-insulated grounding switch.
The invention also concerns a ground disconnect switch comprising such an assembly and a method for making a ground disconnect switch in accordance with the invention.
The interrupt tumbler and/or the ground disconnect tumbler (2, 4) are made of a thermoplastic material, preferably selected from the family of polyoxymethylenes.
