Definitions

  • the invention relates to a device for transmitting electrical energy using a superconducting cable according to the preamble of patent claim 1 .
  • a superconducting current carrier in particular a superconducting cable or a superconducting busbar, comprises at least one electrical conductor element which changes to the superconducting state at a sufficiently low temperature (transition temperature, T c ).
  • T c transition temperature
  • superconductor transition temperatures vary over a wide range, ranging from T c ⁇ 10 K for classic metallic superconductors to values of T c > 100 K for high-temperature ceramic superconductors. The discovery and industrial exploitation of superconductors with an even higher transition temperature in the near future cannot be ruled out.
  • the superconducting cable In order to maintain the superconducting state, the superconducting cable must be cooled with a suitable cooling medium.
  • the superconducting current carrier In order to implement effective cooling, the superconducting current carrier is accommodated, for example, in a tubular or rectangular cooling channel (cryostat), through which the cooling medium is guided during operation.
  • cryostat tubular or rectangular cooling channel
  • Superconducting current carriers of this type are widely known and are described, for example, in EP 2 328 156 A1, EP 2 608 223 A1, or EP 2 793 240 B1.
  • a supercooled, liquefied gas such as liquid nitrogen, liquid oxygen, liquid hydrogen, liquefied natural gas or liquefied noble gas, in particular liquid helium, is used as the cooling medium for cooling superconducting current carriers.
  • “Supercooled liquefied gas” is understood here to mean a gas that is at a temperature below the boiling point at the prevailing pressure.
  • the absorption of heat initially only causes the temperature of the liquefied gas to rise, without a change in the state of aggregation occurring. Examples of such cooling systems are described in US Pat. Nos.
  • the known systems have disadvantages that come into play in particular in the case of long cooling sections.
  • more cooling medium must be fed through the line as the length of the current carrier increases.
  • the increasing volume flow can only be achieved with a larger flow cross section and/or with a greater flow rate.
  • the costs of the arrangement quickly increase to an extent that is no longer economically justifiable; in the latter case, the high flow rate also increases the dissipative heat input due to the friction of the cooling medium on the inner wall of the pipeline and thereby reduces the efficiency of the cooling.
  • a method for cooling objects, in particular superconducting cables, is known from WO 2014 026 873 A1, in which a supercooled cryogenic cooling medium is guided through an annular channel arranged around a superconducting cable.
  • the cooling takes place by means of two reservoirs at both ends of the cable, from which the cooling medium is guided in a pendulum manner through the ring channel is directed. Due to the pendulum guidance, there is no need for an independent return line, through which additional heat is introduced into the system, but the requirement for two storage containers leads to a high level of equipment complexity.
  • US Pat. No. 7,453,041 B1 describes an arrangement for cooling a superconducting cable, in which a superconducting cable is accommodated coaxially in a first (inner) tubular channel which is connected to a feed for a cooling medium.
  • the first duct is accommodated coaxially within a second (outer) tubular duct which is flow-connected to the inner duct at at least one front end of the arrangement and is equipped with an outlet for the cooling medium.
  • a cooling medium with a temperature below the transition temperature of the superconducting cable material for example supercooled liquid nitrogen, is passed through the inner channel and cools the superconducting cable.
  • the cooling medium that is then fed back via the outer channel acts as a heat shield that shields the inner channel from the entry of heat from the environment. In this way, the introduction of heat can be reduced over the entire length of the cable and the arrangement can therefore be designed to be longer.
  • the invention is therefore based on the object of creating a device for the transmission of electrical energy with a superconducting current carrier, which allows efficient cooling of even longer line sections with comparatively little outlay on equipment.
  • a device for transmitting electrical energy with a superconducting current carrier i.e. in particular a cable or a busbar, in which the current carrier to be cooled is accommodated in a first cooling channel, which first cooling channel is connected via a coolant supply line to a supply device for a first cooling medium and with a surrounding the first cooling duct and is equipped with at least one second cooling duct, which is thermally connected and intended for the passage of a second cooling medium, with a supercooled, liquefied gas being used as the first cooling medium, is therefore characterized according to the invention in that the second cooling medium is a liquefied gas is used and the at least one second cooling channel is equipped with at least one gas phase separator.
  • a device thus comprises a first (inner) cooling channel in which a superconducting current carrier to be cooled is arranged and a heat shield which surrounds the first cooling channel and is thermally connected to a second cooling channel through which a second cooling medium flows.
  • the heat shield is, for example, the second cooling duct itself, which is arranged coaxially or in some other way around the first cooling duct, or it is, for example, a tubular construction made of a material with good thermal conductivity, which surrounds the first cooling duct and has one or more through which the second cooling medium flows Channels is thermally connected.
  • a supercooled, liquefied gas such as supercooled liquefied nitrogen, supercooled liquefied oxygen, supercooled liquefied hydrogen, supercooled liquefied natural gas or inert gas, is used to cool the superconducting current carrier the transition temperature of the superconducting cable material remains.
  • the first cooling medium is fed into the first cooling channel at a feed point, which is located, for example, at a head end of a device according to the invention or in the middle region between the two head ends of a device according to the invention.
  • the first cooling medium can also be circulated and subjected to supercooling when it enters the first cooling channel.
  • the cooling medium used in the second cooling channel or the second cooling channels also uses a liquefied gas, which can be the same as or different from the gas used in the first cooling channel.
  • this is at a higher temperature than the cooling medium in the first cooling channel and can at least partially evaporate due to the heat input from the environment;
  • it is therefore not necessary to keep the cooling medium in the second cooling channel constantly in the liquid state - for example by cooling to a corresponding temperature or by applying a corresponding pressure - which means that cooling medium is saved to a not inconsiderable extent can.
  • a gas phase arising due to the evaporation of cooling medium in the second cooling channel is separated from the still liquid second cooling medium in the gas phase separator or in the gas phase separators and removed from the second cooling channel via an exhaust gas line.
  • the gas phase is then released into the ambient atmosphere via the exhaust line or used for some other purpose.
  • the exhaust pipe can also run, at least in sections, through a third cooling duct which runs coaxially around the second cooling duct and which in this case represents an additional heat shield.
  • the separated liquid phase remains in the second cooling channel or is fed back into the flow of the second cooling medium. After passing through the second cooling channel, the liquid phase is used again - replacing the portion of the discharged gas phase and renewed supercooling - for cooling the superconducting cable in the first cooling channel or it is used for another purpose, for example for cooling a power supply connected to the superconducting cable.
  • a layer with a low heat transfer coefficient is provided between the first cooling duct and the heat shield and/or between the first cooling duct and the second cooling duct, which layer allows only the lowest possible heat transfer from the second to the first cooling duct.
  • Thermal insulation such as vacuum insulation, encloses the heat shield and the second cooling duct or the second cooling ducts, or the second cooling duct, if this acts as a heat shield in a coaxial arrangement with the first cooling duct.
  • the gas phase separator preferably comprises a container in which the liquid phase and gas phase are separated by gravity, ie the gas phase collects in a geodetically upper section of the container and is discharged from there via an exhaust pipe.
  • other mechanisms for phase separation can also be used to advantage in the gas phase separator or separators, for example a temperature or pressure controlled fitting or a liquid-tight but gas-permeable membrane.
  • a plurality of gas phase separators arranged at a distance from one another in the longitudinal direction of the second cooling channel are also conceivable according to the invention.
  • the gas phase separator should be arranged within an outer insulation of the device according to the invention, which surrounds the second cooling channel and possibly the third cooling channel, or the gas phase separator has and/or its own highly effective insulation, for example an arrangement within a vacuum chamber.
  • An advantageous embodiment of the invention is characterized in that supercooled second cooling medium is used as the first cooling medium.
  • the first and second cooling medium consist of the same substance, for example liquid nitrogen, and can also be taken from the same reservoir.
  • the cooling medium is supercooled before it is introduced into the first cooling channel - or it is constantly circulated and in each case supercooled before being introduced again into the first cooling channel - and is also always in the supercooled, liquid state within the first cooling channel.
  • the cooling medium introduced from the first into the second cooling channel heats up by a temperature difference of 2K to 10K, for example, due to the heat input from the environment. It can also reach its boiling point temperature and partially evaporate.
  • the cooling medium serves as a heat shield for the cooling medium in the first cooling channel, which in this respect absorbs a smaller amount of heat.
  • the still liquid cooling medium from the second cooling channel can in particular be fed to another cooling task, for example to cool a power supply line.
  • a particularly preferred embodiment of the invention provides for at least one flow connection to be provided between the first and second cooling duct for introducing cooling medium from the first into the second cooling duct.
  • the cooling medium routed through the first cooling channel is therefore identical to the cooling medium routed through the second cooling channel.
  • the cooling medium is therefore supplied in the supercooled state to the first cooling channel, in which it takes over the cooling of the superconducting current carrier, and reaches the second cooling channel via the flow connection or via a plurality of flow connections, in which it acts as a heat shield for the first cooling channel or cools a heat shield thermally connected to the second cooling passage or cooling passages.
  • At least part of the cooling medium can evaporate in the second cooling channel due to the heat input from the environment.
  • the vaporized cooling medium is separated from the liquid phase and discharged.
  • the cooling medium that remains in the liquid state passes through the second cooling channel and can then be used again, for example, it is brought to the operating temperature required for cooling the superconducting current carrier in a subcooler together with fresh cooling medium replacing the gas phase that has been removed and fed back into the first cooling channel.

  • the cooling medium supply line for introducing the first Cooling medium can be arranged at the opposite head section or at another point, approximately in the middle between the two head sections.
