  • Patent number: 11402457
    Abstract: A system and a method for an integrated test on a primary-secondary pole-mounted breaker. The method includes: establishing an electrical connection between the system and the primary-secondary pole-mounted breaker; establishing a communication connection between the system and the primary-secondary pole-mounted breaker; applying, by the system, a voltage signal and a current signal to the primary-secondary pole-mounted breaker through the electrical connection, to generate a voltage and a current on the primary-secondary pole-mounted breaker; collecting, by the system, signals of the voltage and the current fed back from the primary-secondary pole-mounted breaker through the communication connection; performing, by the system, an integrated accuracy test and an integrated protection test; outputting a test result of the accuracy test and a test result of the integrated protection test to the industrial control machine, to generate the test report.

  • Patent number: 11325875
    Abstract: Chiral spirobiindane skeleton compound and preparation method thereof is disclosed in the present invention. The spirobiindane skeleton compound of the present invention having the structure formula of I or I?; the preparation method for synthesizing the spirobiindane skeleton compound of the present invention comprising the following steps: in the presence of solvent and catalysts, the structure formula compound III reacted through intramolecular Friedel-Crafts reaction to obtain the compound of formula I; the catalyst is a Browsteric acidor Lewis acid. The preparation method of chiral fused spirobiindane skeleton compound of the present invention does not need to adopt chiral starting materials or chiral resolving agents, does not require chiral resolving steps, is simple in method, is simple in post-treatment, and is economic and environment friendly. High product yield, high product optical purity and chemical purity.
