Abstract

The invention discloses a terminal structure of a superconducting cable. The terminal structure comprises a current lead-out tube arranged in a terminal sleeve, one end of the current lead-out tube isconductively connected with the superconducting cable; the other end of the current lead-out tube is exposed from the end part of the terminal sleeve to form an exposed end; a cavity is formed in thecurrent leading-out tube, a leading-out hole communicated with the cavity is formed in the exposed end of the current leading-out tube, a sealing cover is arranged on the leading-out hole, a signal lead is arranged in the cavity of the current leading-out tube in a penetrating mode, and the tail end of the signal lead is led out from the sealing cover. According to the invention, the electric field balance of the superconducting cable terminal is ensured, the signal lead is led out from a low-temperature, high-voltage and high-pressure environment, and the measurement of the temperature of acable conductor and the measurement of other non-electric quantities in a high-voltage region can be realized under the condition that a superconducting cable system is put into operation in a net hanging manner.

Description

technical field [0001] The invention relates to a superconducting cable, in particular to a terminal structure of the superconducting cable. Background technique [0002] Superconducting cables are power cables made of superconducting materials, used to transmit high-density electric energy, and have the advantages of low resistance, low loss, and environmental protection. Whether the superconducting material is in the superconducting state is the most critical indicator for the safe operation of the superconducting cable. When the superconducting material is in the deep superconducting state, its ability to transmit electric energy is the strongest, and it can also be considered that the superconducting cable is basically in a safe state. The most direct way to monitor whether a superconducting material is in a superconducting state is to measure the temperature of the superconducting material in the conductor layer. Requirements, it is difficult to arrange the temperature...
