| titleOfInvention | Tunnel magnetic resistance and Rogowski coil combined totally-enclosed current testing device |
| abstract | The invention discloses a tunnel magnetic resistance and Rogowski coil combined totally-enclosed current testing device. The current testing device adopts a shielding structure of a totally enclosed metal shell, a double-layer waveguide window and an electromagnetic sealing gasket filling joint, the output signal of a sensor is digitally processed in the metal shell, the digitally processed signal is locally stored or transmitted by optical fiber data, and meanwhile, laser charging is used, so that the anti-electromagnetic interference performance of the current testing device is improved; after all parts of the device are installed, system-level calibration (calibration) is carried out in a laboratory, errors caused by installation of a sensor on a test site are avoided, and system errors are reduced; the device utilizes the tunnel magnetoresistive sensor to measure the combination of steady state (middle and low frequency) and Rogowski coil to measure the signal phase of the pulse power current (middle and high frequency), and realizes the full-frequency-band test of the pulse power current. |
