Description
Technical field
Superconducting coil technical field is the utility model is related to, and more particularly, to the nonisulated superconducting coil of encapsulating.
The situation that quenches of superconducting coil, stabilization of the hold-in winding on mechanics, electricity, thermal property can effectively be avoided.
Background technology
The Ka Molinangnasi of Leiden, Netherlands (Leiden) university in 1911 is taught finds that superconduction shows first in laboratory
As since, superconductor and its application always one of most active research frontier of contemporary science and technology.Past ten
Between several years, the research rapid development of the superconducting power apparatus based on high-temperature superconductor, in superconducting energy storage, superconducting motor, superconduct
The fields such as cable, superconductive current limiter, superconducting transformer, super-conductive magnetic suspension, nuclear magnetic resonance obtain notable achievement.
The practical application of superconducting coil needs to consider coil mechanics, electricity, calorifics each side situation.
The material properties of superconducting conductor determine that itself is more fragile, and material is by certain bending, stretching, distortion etc.
After stress, superconducting conductor is extremely easily damaged in itself, its critical current is declined to a great extent.During superconducting coil normal work, superconduction
Conductor under the influence of a magnetic field often can be by larger electromagnetic stress.In addition the outside mechanical oscillation that superconducting coil is subject to, can be passed
Lead to superconducting conductor.Especially superconducting motor, super-conductive magnetic suspension such application environment under, resonance, shake are inevitable.Nothing
By being propagated by electromagnetic stress or vibration, if certain section of superconducting conductor has trickle vibration, time one in superconducting coil
Length can cause the fatigue of material to make its hydraulic performance decline, so as to influence the performance of whole superconducting coil.
Current conventional superconducting coil would generally carry out vacuum impregnation, but this to it in application with paraffin or epoxy resin
The problem of can bring one of kind of technique is serious is that technique is possible to can have destruction in itself to conductor in itself.It is broken
Bad mechanism is the material of paraffin or epoxy resin and superconducting conductor composition, and coefficient of thermal expansion and contraction is different at low temperature, surpasses
The paraffin or epoxy resin of conductor both sides easily vertically apply to peel off along peeling direction to superconductivity wire during cooling answers
Power.Especially yttrium system superconducting conductor is a kind of multilayer coating material, and when inter-layer bonding force is weaker than peel stress, conductor performance will occur
Huge loses.Even if do not occur this problem after vacuum impregnation at the beginning, but the multiple cold cycling when superconducting coil is applied
After, this problem will also occur.The harmful effect of superconducting coil terms of mechanics can restrict if it cannot solve very well
The application of superconducting coil.
The electric property of superconducting conductor is the most important index of superconducting conductor, and it is related to the application of superconducting coil.Superconduction
The most important index of conductor electric property is critical current, and the electric current carried in superconducting conductor exceedes critical current, superconducting conductor
Superconductivity will be lost, this section of conductor is shown as and possesses certain resistance.The critical current and temperature of superconducting conductor and magnetic field
There is very big relation, with the rise of temperature, the critical current of superconducting conductor can reduce, with the rise in magnetic field, superconducting conductor
Critical current can also can reduce.Superconducting tape is quenched often since a most weak point in superconducting coil, and it is quenched
After possess certain resistance, generate heat under the function of current, form hot spot.And hot spot can make the critical electricity of this section of superconducting conductor
Stream is reduced, and by such positive feedback process, if process cannot effectively suppress, quenching for this point can also be led along superconduction
Body direction is spread, and ultimately results in superconducting conductor burning partly or wholly.Superconducting coil in the application, loses Just because of this
Super detection and protection seems particularly significant.But especially high-temperature superconductor conductor, its conductor are ceramic oxide in itself, generally
Of a relatively high 30~77K of temperature range is operated in, the propagation of heat wants slowly more compared with the metal of low-temperature superconducting conductor, can not
Monitor to quench signal in time by monitoring traditional method such as coil voltage, therefore be difficult to be detected and protected.Quench guarantor
Shield is one of key issue of puzzle high temperature superconductor coil technology development, this be also superconducting coil some safety requirements compared with
The restraining factors applied in high engineering.
The refrigeration of superconducting conductor is the key of its application, because the temperature of superconducting conductor directly affects its electricity mechanical property
Energy.Refrigeration is also related to the cost of superconducting coil application, is more related to the safety of superconducting coil application.Especially in application scenario,
Ensure refrigerating efficiency, take away in time because local superconducting conductor quenches the hot spot to be formed, the stable operation to superconducting coil has
Highly important meaning.Superconducting coil in the application, generally there is two kinds of types of cooling, and the first is bubble such as liquid in coolant
Nitrogen, liquid helium, second is that coil is freezed with refrigeration machine.Ripe superconducting coil is still with refrigeration machine system at present
Cold, reason is that refrigeration machine can reach lower temperature in addition to the liquid helium of costliness, has superconducting conductor higher
Electric property, so as to embody its stronger cost performance；Other refrigeration machine electricity consumption, it is more convenient, will to application site operating mode
Ask not high.During using refrigeration machine cooling, in order to prevent heat losses, superconducting magnet can be put into the vacuum dewar of a sealing
In, cryocooler cold head is goed deep into be bonded conduction cooling inside Dewar with superconducting magnet.If superconducting conductor turn-to-turn in superconducting magnet
Have if space is not filled, this part becomes vacuum state, is extremely unfavorable for conduction cooling.Now if conductor due to
Hot spot caused by quenching just is not easy to be pulled away by conducting cooling immediately very much, ultimately results in the appearance of big problem.High-temperature superconductor
The superconducting tape of coil outsourcing insulation multi-purpose greatly or wire rod coiling form.Similar with traditional enamel-covered wire, the presence of insulating barrier is
In order to prevent coil turn-to-turn short circuit.But insulating layer material such as polyimide, PPLP or epoxy resin are mostly the non-conductor of heat,
Become the obstacle in coil refrigeration path.When especially being quenched in coil because of excessively stream or hot-spot, insulating barrier
Presence can hinder heat scatter and disappear, cause first to burn when serious.
2011, Hahn proposed the concept of superconduction naked coil.In this coil, it is exhausted coil turn-to-turn has been banned
Edge, that is, prepare the superconducting tape surface of coil not spray insulation material.The superconducting coil of this turn-to-turn naked avoids insulation
Superconducting magnet with quench phenomenon to magnet band come potential hazard.In naked superconducting coil preparation process, adjacent
The non-insulating material with certain electric conductivity is filled between superconducting tape.Naked coil once quenches, and quenching electric current can lead to
Cross adjacent interlayer to flow through, so that it is guaranteed that superconducting coil being capable of normal work.Meanwhile the non-insulating material between band has well
Thermal conductivity, therefore the heat quenched a little with Quick diffusing, can effectively improve the heat endurance of coil.But its cost for paying
It is the discharge and recharge time of coil.The discharge and recharge time of coil depends on an equivalent RL parallel circuit of whole naked coil.
Inductance therein is the inductance of coil itself, and resistance is equivalent radial direction resistance of the electric current when turn-to-turn flows.Coil winding is completed
Afterwards, inductance change is little, but the equivalent radial direction resistance variations of the turn-to-turn of coil are huge.Because superconducting coil is by cold during application
After thermal cycle, the pore size that can change between adjacent superconductivity wire of expanding with heat and contract with cold, so as to vary widely radial direction resistance.
Such change can cause the superconducting coil discharge and recharge time to have huge change, be unfavorable for the engineering application of superconducting coil.
