Abstract
The invention relates to a disconnecting switch assembly for disconnecting air-insulated electrical lines, which have one or more phases, with at least one grounded housing that is filled with protective gas, with open air ducts, which are attached to the housing(s) in a gastight manner and which each have an open-air connection for connecting the lines, and with gas-insulated disconnecting switches, which are placed inside the open-air ducts. At least three open air ducts are provided for each phase whose open-air connections can be electrically connected to one another by means of the disconnecting switch over current path piece mounted inside the housing.
Claims17
A switch disconnector arrangement (1) for disconnection of air-insulated electrical lines which have one or more phases, having at least one grounded enclosure (2) which is filled with inert gas, having outdoor bushings (4) which are attached to the enclosure or enclosures (2) in a gas-tight manner and each have an outdoor connection (11) for connection of the lines, and having gas-insulated switch disconnectors (7) which are arranged in the outdoor bushings (4), with at least three outdoor bushings (4) being provided for each phase, whose outdoor connections (11) can be electrically connected to one another by means of the switch disconnectors (7) via a pole element (16) which is arranged in one of the enclosures (2), and with each outdoor bushing (4) having a switch disconnector (7).
The switch disconnector arrangement (1) as claimed in claim 5, wherein
- each grounding switch (29) is arranged in an outdoor bushing (4).
The switch disconnector arrangement (1) as claimed in claim 7, wherein
- the holding means (23) are gas-tight.
The switch disconnector arrangement (1) as claimed in claim 10, wherein
- the switch disconnector (7) has a stationary female contact (8) and a sliding contact (9), which is firmly supported via a hollow connecting rod (14) on attachment means (17) for the outdoor bushing (4), with a switching pin (13), which is guided by the sliding contact (9) such that it can move, being provided for making contact with the female contact (8), and being driven via drive means (25, 26) which are arranged in the connecting conductor (14).
