  • Publication number: 20220413062
    Abstract: An AC/DC leakage detection method, which supports the detection of DC leakage and AC leakage. A DC leakage current and a low-frequency leakage current are measured by means of magnetic modulation technology, an AC signal is measured in the form of pure induction, and two detection modes are performed in a time-sharing manner. A collected leakage signal is converted into a digital signal through an AD converter. By means of the method of the present invention, the processing of a leakage signal is divided into three channels for respectively processing DC leakage, low-frequency AC leakage, and high-frequency AC leakage. The overall effective value of residual current is calculated by integrating results of DC detection and AC detection. The method of the present invention supports the detection of a suddenly increased current; and when there is a suddenly increased current, detection mode switching is performed by detecting the current sudden change of the current.

  • Publication number: 20220390501
    Abstract: A fault-arc identification method, device and apparatus, and a storage medium. The method comprises: performing sampling on a target arc at a high frequency, and obtaining a high-frequency sampling signal (S11); preprocessing the high-frequency sampling signal, and obtaining a processed sampling signal (S12); performing feature extraction on the processed sampling signal, and obtaining a target arc feature (S13); and inputting the target arc feature to a neural network model, obtaining a target output result, and determining, according to the target output result, whether the target arc is a fault-arc (S14). Performing sampling on a target arc at a high frequency can obtain more arc features from the target arc. Moreover, since a neural network model has favorable data classification capability, using a neural network model to perform determination with respect to the target arc can improve the accuracy and reliability of a fault-arc detection result.

  • Publication number: 20220375704
    Abstract: A pulse voltage conditioning method of a vacuum interrupter with automatic conditioning energy adjustment based on a trend of a breakdown voltage of the vacuum interrupter during a conditioning process. A current-limiting resistor and a parallel capacitor are automatically adjusted to ensure the conditioning energy reaching a critical value without deconditioning effect. The critical value refers to a maximum conditioning energy without damaging the electrode surfaces, namely an optimal conditioning energy, which can better remove insulation defects on the electrode surface and improve insulation performance of a vacuum gap. The problems of insufficient conditioning and deconditioning effect during conventional voltage conditioning process of the vacuum interrupter can be solved. Therefore, insulation strength of the vacuum interrupter can be raised to a higher level through conditioning.

  • Publication number: 20220275547
    Abstract: A method of forming a sheet material. The method comprises advancing an arrangement comprising a body of fibres and a reinforcing structure, wherein the reinforcing structure comprises splittable fibres. The method further comprises subjecting the arrangement to successive hydroentanglement steps, wherein in each such hydroentanglement step the arrangement is exposed to high pressure jets of liquid over a surface of the arrangement. Subjecting the arrangement to successive hydroentanglement steps causes the fibres of the body of fibres to entangle with each other and causes a mechanical bond to form between the fibres of the body of fibres and the reinforcing structure.
