  • Patent number: 11815564
    Abstract: A method for analyzing a correlation between rail transit and direct current (DC) magnetic bias of a transformer includes the steps of, A: obtaining a current of a feed cable and a DC magnetic bias current: measuring the feed cable current in rail transit and the DC magnetic bias current of a transformer in a power grid within a certain period by a monitoring apparatus; B: calculating a characteristic quantity of the feed current within the measurement period based on the obtained current of the feed cable; C: calculating a characteristic quantity of the DC magnetic bias current within the measurement period based on the DC magnetic bias current; and D: calculating a support degree and a confidence coefficient based on the calculated characteristic quantity of the feed current and the calculated characteristic quantity of the DC magnetic bias current, and generating a correlation rule.

  • Patent number: 10480574
    Abstract: An adjustable lubrication module of a linear guideway includes an end lid disposed at a slider and an oil scraper disposed at the end lid. The end lid has therein two opposing backflow-chambers. A feed-hole disposed between the backflow-chambers and an oil-guiding conduit disposed below the feed-hole are disposed on the end lid. Communication between the feed-hole and the oil-guiding conduit is achieved by a primary oiling-channel. Communications between the oil-guiding conduit and the backflow-chambers are achieved by a secondary oiling-channel. Therefore, oiling-channel adjustment performed on the adjustable lubrication module operating in conjunction with the linear guideway does not entail demounting the end lid from the slider, thereby preventing ball missing. The feed-hole and the oil-guiding conduit are not disposed at the junction of the end lid and the slider; hence, lubrication oil is prevented from flowing over the gap between the end lid and the slider.

  • Publication number: 20150185270
    Abstract: A method for recognizing a transformer partial discharge pattern based on a singular value decomposition (SVD) algorithm includes a training model and a classification recognizing process, comprising: firstly setting up an experimental environment having artificial defects, collecting at least one datum sample, and calculating statistical feature parameters of each datum sample to form a datum sample matrix; performing singular value decomposition on the datum sample matrix and determining an order of an optimal retention matrix by judging whether a feature of a retention matrix is clear, so as to obtain a type feature description matrix and a class-center description vector group after dimensionality reduction; preprocessing samples to be recognized to obtain a sample vector, and performing linear transformation on the sample vector utilizing a type space description matrix.
