Chemical synthesis of insulin superfamily proteins (ISPs) has recently been widely studied to develop next‐generation drugs. Separate synthesis of multiple peptide fragments and tedious chain‐to‐chain folding are usually encountered in these studies, limiting accessibility to ISP derivatives. Here we report the finding that insulin superfamily proteins (e.g. H2 relaxin, insulin itself, and H3 relaxin)...

In 2004, Innopower began the R&D work to develop saturated iron core type SFCL. The initial reasons to choose this technology are to avoid the direct impact by the quench of the superconductor coils during fault current limiting, which results in long recovery time and complicated protection requirement. The saturated iron core type SFCL have been proved to be practical and suitable for utility...
Saturated Iron-core Superconducting Fault Current Limiter (SISFCL) has superior properties as a fault current limiting device. DC excitation system plays a key role during the operation of SISFCL. Besides its basic function, outputting DC excitation current to keep Iron-core saturated, its field suppression unit absorbs magnetic energy stored in superconducting coil and suppresses the reverse voltage...
High reliability is one of the key requirements for a power grid device. The reliability of a superconducting fault current limiter (SFCL) largely depends on the reliability of its cryogenic system. An open cryogenic system was designed and fabricated for a 220 kV / 300 MVA saturated iron-core SFCL, which composed of a dewar, heat insulation pipelines, a liquid nitrogen tank, a control circuit, and...
A large size Bi-2223 HTS magnet coil were manufactured and tested. The HTS coil comprises 45 double pancakes which are grouped into 5 sets. Each set has 9 pancakes connected in series and the 5 sets are connected in parallel to form the coil. The coil has a diameter of 2.1 meters and total turns of 2520. The Ic of the coil is 350 A at 77 K. During and after manufacture of the HTS coil, a series of...
A Saturated Iron Core Superconducting Fault Current Limiter (SICSFCL) provides a powerful fault current limitation in high voltage and high capacity power grid. A 35kV/90MVA SICSFCL was installed in a 35 kV network for live-grid operation, in January 2008 at Puji substation, Kunming, China. With deep research on SICSFCL, the matching problem between SICSFCL and relay protection currently needs to...
