A vacuum shell of a large-capacity annular energy storage magnet

Abstract

The invention provides a vacuum housing of a large-capacity annular energy storage magnet, which includes upper and lower housings and support frames arranged at the axial centers of the upper and lower housings, and the upper and lower housings are fastened by calipers to seal the flanges connection, the top of the upper housing is provided with a circular through hole for installing a circular top plate, the upper and lower housings are single-layer stainless steel structures, the side walls and bottom transition surfaces of the upper and lower housings Both are arc-shaped, the outer sides of the upper and lower shells are provided with reinforcing ribs in an array, the inner edge of the bottom surface of the lower shell is provided with annular array support blocks, and the outer annular array is provided with support legs. The vacuum shell of the present invention has a simple structure and can reduce the The system is difficult to operate during the assembly and maintenance process. The upper and lower shells are single-layer stainless steel structures, which provide a large space for the internal annular energy storage magnets. The upper and lower shells are arrayed with reinforcing ribs outside to ensure structural strength. , the setting of the support frame is beneficial to strengthen the structural strength and isolate the magnet from the internal operating space.

Description

Technical field: [0001] The invention relates to a vacuum housing, in particular to a vacuum housing of a large-capacity annular energy storage magnet. Background technique: [0002] The calculation of system energy storage is used to estimate the overall size of the system. The high-temperature superconducting tape magnet generally adopts the double-cake coil technology formed and wound by a single conductor. , multiple double pie coils are merged side by side to form a group of unit coil windings. The energy storage magnet system is composed of multiple unit coil windings symmetrically formed along the ring direction. The size of the stored energy is proportional to the size of the coil and the number of coil units. The larger the capacity , the larger the size of the coil, the more the number of coil units, the larger the space to accommodate its energy storage magnets, and the vacuum housings in the prior art generally have shortcomings such as small space, low strength,...

[0002] The calculation of system energy storage is used to estimate the overall size of the system. The high-temperature superconducting tape magnet generally adopts the double-cake coil technology formed and wound by a single conductor. , multiple double pie coils are merged side by side to form a group of unit coil windings. The energy storage magnet system is composed of multiple unit coil windings symmetrically formed along the ring direction. The size of the stored energy is proportional to the size of the coil and the number of coil units. The larger the capacity , the larger the size of the coil, the more the number of coil units, the larger the space to accommodate its energy storage magnets, and the vacuum housings in the prior art generally have shortcomings such as small space, low strength, and complex structure. Therefore, a The vacuum shell of the large-capacity annular energy storage magnet is particularly important
