Abstract: The present disclosure relates to a gas tank for a switchgear, assembling method and switchgear. A gas tank (1) for a switchgear, includes: a front wall (10), a rear wall (20) opposite to the front wall (10), a top wall (30), a bottom wall (40) opposite to the top wall (30) and a pair of side walls (51, 52), for forming a chamber (100), each side wall of the pair of side walls (51, 52) being attached to side edges of the front wall (10), the rear wall (20), the top wall (30) and the bottom wall (40), where each wall of the front wall (10), the rear wall (20), the top wall (30) and the bottom wall (40) includes bent portions (11, 21, 31, 41), the bent portions (11, 21, 31, 41) being arranged on opposite sides of the front wall (10), of the rear wall (20), of the top wall (30) and of the bottom wall (40) respectively and adjacent to the side edges and the bent portions (11, 21, 31, 41) being folded from the body portions (12, 22, 32, 42) of the front wall (10), the rear wall (20), the top wall (30) and the bottom wall (40), and where the front wall (10), the rear wall (20), the top wall (30) and the bottom wall (40) are configured to be mounted in place by means of a connection portion between each wall of the front wall (10), the rear wall (20), the top wall (30) and the bottom wall (40) and the bent portion (11, 21, 31, 41) of a wall adjacent to the wall. With such design, the structural strength of the gas tank (1) of the switchgear can be significantly improved.

Abstract: The invention provides a cooling device (1) for a Gas Insulated Switchgear. The cooling device (1 ) comprises a condenser (11) arranged outside the gas chamber (2), an evaporation part (13) arranged in the gas chamber, and at least one fluid conduit (12) connect the evaporator device (13) and the condenser (11); the fluid conduit (11 ) is heat conductive and is filled with low-boiling condensate (120) to transfer heat from the evaporation part (13) to the condenser (11). The evaporation part (13) and the at least one fluid conduit (12) can be integrated together, and the evaporation part (13) is the gas chamber end of the at least one fluid conduit (12). Or the condenser (11) is a separated part and it is liquid connective with al! the fluid conduits (12). The condenser (11 ) comprising a heat sink (110) which is connected with the fluid conduit (12) and is arranged outside of the gas chamber (2).
