  • Patent number: 12247971
    Abstract: A method for evaluating an aging state of a silicone rubber composite insulator includes: step 1: collecting samples from the silicone rubber composite insulator, and subjecting samples in a surface layer and a center layer successively to hydrophobicity, flexing resistance, hardness, color, and absorbance tests; step 2: determining relevant data of the samples in a natural evolution process according to the tests in step 1; step 3: subjecting the samples to thermo-oxidative aging; and after the thermo-oxidative aging is completed, subjecting the samples to a hardness test of artificial accelerated evolution, and calculating position coordinates (F1, F2) of the samples in an aging space; and step 4: classifying the samples in advance and solving an aging state centroid of each classified population, calculating a minimum aging distance based on the position coordinates in step 3, and evaluating the aging state of the silicone rubber composite insulator.

  • Publication number: 20240337696
    Abstract: A method comprises recording a first voltage value of a voltage source, recording a second voltage value of the voltage source, and determining a first estimated residual state of charge value (SOCestimated) of the voltage source based on the first voltage value and the second voltage value. The method also comprises determining a factor based on one of the first voltage value and the second voltage value and calculating a residual state of charge value (SOCresidual) of the voltage source based on the first estimated residual state of charge value (SOCestimated) and based on the factor.

  • Patent number: 11327114
    Abstract: The fully-automatic closed-loop detection method includes: comparing a SCD file of a to-be-tested substation with a device-type data template file, so as to determine whether configuration information about the to-be-tested substation is correct; when the configuration information about the to-be-tested substation is correct, parsing the SCD file of the to-be-tested substation and generating a SSD topological diagram of the to-be-tested substation; and acquiring a testing item from a predetermined testing item library in accordance with the SSD topological diagram of the to-be-tested substation, generating a testing scheme for the to-be-tested substation, performing a testing operation and outputting a testing result.

  • Patent number: 10688546
    Abstract: Disclosed is a biogas residue-based in situ and ectopic coupled detoxification method for hexavalent chromium site and soil remediation agent. The method is applied to chromium-containing soil by formulating biogas residue, a carbon source and a sulfate into said soil remediation agent. Special construction and maintenance methods are adopted to achieve effective reduction of hexavalent chromium in deep contaminated soil. Therefore, the biogas residue-based in situ and ectopic coupled detoxification method for hexavalent chromium-containing sites cannot only be used to remediate chromium-containing sites deep in depth at a low cost and high efficiency, but also achieve recycled utilization of waste by treating waste with one another, thereby possessing significant value in promotion and practice.

  • Patent number: 10596606
    Abstract: Disclosed is an in-situ detoxification method for a heavily contaminated site by hexavalent chromium. The method includes injecting a chemical reducing agent into a site heavily contaminated with hexavalent chromium, and injecting a chromium soil remediation microbial agent into the site after 0-10 days. The in-situ detoxification method includes: first, in-situ injecting the chemical reducing agent into the soil, preliminarily reducing high-concentration hexavalent chromium such that the hexavalent chromium of high concentration has no toxic effect on the subsequent ecological microbial agent, then in-situ injecting the ecological microbial agent prepared from biogas residue, a carbon source and sulfate into the chromium-containing soil under pressure, and forming a large-scale reducing buffer zone containing sulfate-reducing bacteria and sulfide in a special maintenance manner in the subsurface soil of the site to reduce the hexavalent chromium continuously and effectively.
