Description
Technical field
The present invention relates to a kind of superconducting power device, particularly relate to a kind of two-sided immersion superconducting solenoid coil.
Background technology
The superconducting power device is one of important development direction in the Electrical Power Technology field.Most of superconducting power device, for example the core of superconducting magnet, superconductive current limiter, superconducting motor and superconducting transformer etc. all is one or more superconducting coils, these superconducting coils can obtain cooling by being immersed in liquid nitrogen or the liquid helium, keep its superconducting state.Superconducting coil can be formed by superconducting wire or superconducting tape coiling, and its shape can coiling become pie or magnetic plug, and pie is made the input and output tap easily, also fixes by the mode of dipping epoxy easily; Magnetic plug is simple in structure, and with respect to pie, big with liquid nitrogen contact area around it, good stability.
Superconducting coil is because the without hindrance characteristic of its superconduction, in the time of in working order, can be lossless by electric current up to thousands of amperes, so superconducting coil also usually is applied in the high current power application, in big electric power is used, superconducting tape can stand very big electromagnetic force, under the effect of this electromagnetic force, move even small position takes place superconducting tape, also may produce is enough to make that superconducting tape loses the energy of superconducting state, and superconducting coil all needs to be fixed up usually thus, promptly pass through epoxy impregnation, or by paraffin curing, or on coil rack, make the groove that holds superconducting tape, avoid superconducting tape coil axis direction along the line to move.
Superconducting coil loses superconducting state, when being called for short quench, superconducting coil loses without hindrance characteristic, resistance appears, will be owing to Joule effect produces a large amount of heats, cause the part or the bulk temperature of coil to rise rapidly, under the serious situation, can cause the performance degradation of superconducting coil or burn, cause enormous economic loss, for fear of this serious situation, need be at superconducting coil quench adstante febre, as much as possible its heat is taken away, or allowed superconducting coil quick integral quench as far as possible, allow heat be evenly distributed in the superconducting coil as far as possible.
The main mode of taking away the superconducting coil heat of liquid nitrogen or liquid helium immersion cooling is to utilize the volatile zone of liquid nitrogen or liquid helium to walk heat, the cooling capacity of liquid nitrogen or liquid helium, be to be directly proportional with the contact area of superconducting tape, promptly big more with the superconducting tape contact area, then cooling capacity is also just strong more, when the superconducting coil quench, also can take away many more heats.Described cooling capacity is also referred to as the heat-transfer capability of superconducting coil, is one of the important indicator that is related to the stability of superconducting coil.
For fixing superconducting tape, on the coil rack of superconducting solenoid coil, can make the groove that holds superconducting tape, when superconducting tape was arranged in this groove, a side zone face closely contacted with coil rack, and the opposite side zone face comes out and contacts with liquid nitrogen or liquid helium.For fear of short circuit, coil rack generally adopts epoxy resin or other insulating material to make, these material thermal transmission coefficients are little, can cause a side zone face of superconducting tape can be in the approximate adiabatic environment thus, only the surface heat transfer that contacts with liquid nitrogen or liquid helium of dependence can cause the decline of superconducting solenoid heat-transfer capability like this.
