Embodiment Construction

[0016] The following will be combined with Figure 1-2 The present invention is described in further detail.

[0017] like figure 1 and 2 Shown are respectively a perspective view and an embodiment of an anti-creepage pie-type coil insulation support frame according to the present invention. figure 1 The embodiment in is used for the perspective view of the insulating support frame after the superconducting tape is placed in the pie coil. The anti-creepage pie coil insulation support frame includes a base 1 made of insulating material, and a plurality of trapezoidal bosses 2 are arranged at intervals along the length direction of the base on both sides of the base 1, and the number of trapezoidal bosses on both sides is Equal and one-to-one correspondence along the transverse direction of the base 1, a platform supporting the superconducting strip 4 is formed between the two trapezoidal bosses in the transverse direction, and a groove 3 that runs through the entire transver...

Abstract

The invention relates to an anti-creepage cake-type coil insulation support frame which comprises a base made of an insulating material. A plurality of bosses are arranged on the two sides of the baseat intervals in the length direction of the base; the bosses on the two sides are equal in number and are in one-to-one correspondence in the transverse direction of the base; a platform for supporting a superconducting tape is formed between the two bosses in the transverse direction, and a groove penetrating through the whole transverse length of the base is formed between the two bosses in thelongitudinal direction. According to the invention, the whole structure is wavy; the bending radius can be reduced; the structure is mainly used for a cake-type resistance-type superconducting current limiter and plays a role in insulation and supporting; on one hand, the groove is indirectly formed, so that the contact area with liquid nitrogen can be increased, and heat exchange is improved; and on the other hand, the bosses are arranged on the two sides of the wave tape at intervals, so that the superconducting tape can be fixed, and creepage can be prevented.

Description

technical field [0001] The invention relates to an anti-creepage cake-type coil insulating support frame, which belongs to the technical field of superconducting current limiters. Background technique [0002] Since the discovery of low-temperature superconductivity at the beginning of the 20th century, people have tried to use superconductivity in the field of engineering. In order to develop superconducting equipment, such as superconducting cables, superconducting current limiters, superconducting energy storage equipment, superconducting generators, superconducting transformers, etc. Among them, the superconducting current limiter is an effective short-circuit current limiting device. When a short-circuit fault occurs, it can quickly limit the short-circuit current to an acceptable level, thereby avoiding the large short-circuit current in the power grid from affecting the safety and stability of the power grid and electrical equipment. The operation poses a major hazar...
