High-voltage switchgear
View Patent ↗A metal-encapsulated, gas-insulated high-voltage switchgear assembly includes a three-phase encapsulated busbar housing, at least one busbar disposed in the housing, and at least three single-phase-encapsulated circuit breakers disposed horizontally. The assembly further includes a busbar splitting module having at least one three-phase connecting flange configured to connect to the busbar housing and at least three single-phase connecting flanges pointing downward configured to connect to the at least three single-phase-encapsulated circuit breakers and an outgoer splitting module having at least one three-phase flange and at least three single-phase flanges pointing downward and configured to connect the at least three single-phase-encapsulated circuit breakers to a three-phase-encapsulated outgoer housing.
1. A metal-encapsulated, gas-insulated high-voltage switchgear assembly comprising:
a three-phase encapsulated busbar housing;
at least one busbar disposed in the housing;
at least three single-phase-encapsulated circuit breakers disposed horizontally;
a busbar splitting module having at least one three-phase connecting flange configured to connect to the busbar housing and at least three single-phase connecting flanges pointing downward configured to connect to the at least three single-phase-encapsulated circuit breakers; and
an outgoer splitting module having at least one three-phase flange and at least three single-phase flanges pointing downward and configured to connect the at least three single-phase-encapsulated circuit breakers to a three-phase-encapsulated outgoer housing.
2. The high-voltage switchgear assembly as recited in claim 1 , further comprising at least one isolator and at least one grounding element disposed in the busbar housing, each one of the at least one isolator and at least one grounding element being associated with the at least one busbar.
3. The high-voltage switchgear assembly as recited in claim 1 , further comprising at least one extension tube for each phase disposed between the outgoer splitting module and the at least three single-phase-encapsulated circuit breakers.
4. The high-voltage switchgear assembly as recited in claim 1 , further comprising an outgoer flange configured to connect the outgoer housing and an angle module disposed on the outgoer splitting module and having an adaptor flange configured to connect one of a voltage converter and a test adapter.
5. The high-voltage switchgear assembly as recited claim 1 , further comprising a gangway disposed between the busbar splitting module and the outgoer splitting module and extending parallel to the busbar housing.
6. The high-voltage switchgear assembly as recited in claim 1 , further comprising a control cabinet having an L-shaped housing and partially clasping the busbar housing.
7. The high-voltage switchgear assembly as recited in claim 6 , wherein the control cabinet occupies only a part of a width of a switch panel.
8. The high-voltage switchgear assembly as recited in claim 1 , further comprising at least four three-phase connecting flanges disposed on the busbar splitting module.
9. The high-voltage switchgear assembly as recited in claim 8 , wherein the busbar splitting module has a cylindrical housing body, and at least four three-phase connecting stubs project in a radial direction out of the busbar splitting module, each being attached to one of the at least four three-phase connecting flanges.
10. The high-voltage switchgear assembly as recited in claim 9 , wherein each one of the at least four three-phase connecting stubs is disposed offset with respect to an adjacent one of the at least four three-phase connecting stubs in an axial direction and in a circumferential direction of the cylindrical housing body.
