Gas cooler for a medium voltage switchgear assembly
TA gas cooler for a medium voltage switchgear assembly with a gas compartment, having a housing with a hollow body for accommodating the heated gas, which flows through the medium voltage switchgear assembly and is heated by at least one heat-generating current conductor, wherein the hollow body of the housing is divided at least partly in several parallel hollow bodies, which are shaped as fins.
1. A gas cooled switchgear system comprising:
a switchgear assembly having an interior;
a gas compartment including a hollow housing forming an area to accommodate heated gas and a plurality of parallel hollow fins extending from an upper side of the housing, an interior of each of the plurality of hollow fins communicating with the gas compartment,
wherein the housing is detachably disposed on the switchgear assembly without being an integral part of the switchgear assembly such that the gas compartment of the housing communicates with the interior of the switchgear assembly such that heated gas from the interior of the switchgear assembly flows into the gas compartment and the fins,
wherein a bottom of each fin of the plurality of fins has a smaller cross-section at a side of the fin closest to the gas compartment and a larger cross-section at a side of the fin farthest from the gas compartment.
2. The gas cooled switchgear system of claim 1 , wherein the fins are directly arranged on the housing.
3. The gas cooled switchgear system of claim 1 , wherein the fins are arranged symmetrically.
4. The gas cooled switchgear system of claim 1 , wherein the fins include a plain sheet metal.
5. The gas cooled switchgear system of claim 1 , wherein the fins are made of plain sheet metal.
6. The gas cooled switchgear system of claim 4 , wherein the plain sheet metal is steel or stainless steel.
7. The gas cooled switchgear system of claim 4 , wherein the plain sheet metal includes steel.
8. The gas cooled switchgear system of claim 6 , wherein the fins are made of deep drawn profiles.
9. The gas cooled switchgear system of claim 1 , wherein the fins are coated so as to increase radiation.
10. The gas cooled switchgear system of claim 1 , wherein the fins are arranged vertically.
11. The gas cooled switchgear system of claim 1 , wherein the fins are arranged horizontally.
12. The gas cooled switchgear system of claim 1 , wherein the fins continue or exceed the geometry of the gas compartment.
13. The gas cooled switchgear system of claim 1 , wherein the gas compartment is connected in a fixed manner to the switchgear assembly.
