YBCO high-temperature superconductive film band connection technology and special-purpose auxiliary clamp thereof
The invention discloses an YBCO high-temperature superconductive film band connection technology and a special-purpose auxiliary clamp thereof. Through the specific connection clamp and its technological parameter, two high-temperature superconductive film bands are rapidly connected by a low temperature solder in short time, and low joint resistance value and good mechanical strength are provided. The whole technological parameter can be accurately optimized, for the solder with melting point lower than 140 DEG C, the welding temperature approaches to 155 DEG C, heating time is 20 minutes, and the clamp temperature is cooled to 129 DEG C and is placed on a steel plate for rapidly cooling. Through the above parameters, joint resistance magnitude order can reach 10<-7> omega even connection length is 1cm, and the resistance value can be lower if the connection length is greater than 1cm. The connection technology of the YBCO high-temperature superconductive film band has the advantages of rapid, convenient operation, high efficiency, low temperature during the connection process and short time, and is suitable for industrial application.
