ZXBXZ series substation AC withstand voltage resonance device is mainly designed and manufactured for AC withstand voltage test equipment of primary electrical equipment in substations below 500kV. It can meet the requirements of transformers, GIS systems, SF6 switches, CT/PT, insulators, bus bars, cables, bushings, etc. AC withstand voltage test of sexual equipment. According to the requirements of the test procedures for the withstand voltage of primary electrical equipment in substations of 220kV and below, the corresponding AC/DC current withstand test equipment should not only meet the test conditions of high voltage and small current, but also meet the test conditions of low voltage and high current, and it is necessary to take into account the requirements. Wide range of application, using the principle of series resonance, the main equipment is composed of a variable frequency power supply control box (operating table), an excitation transformer, a reactor, and a capacitor voltage divider. On the capacitor voltage divider, the rectifier silicon stack and the Microammeter, the DC withstand voltage test can be completed. Because the system has good filtering characteristics after resonance, the DC voltage produced by it is better than the DC voltage that is first rectified by the ordinary test transformer. It is an ideal pressure-resistant equipment for high-voltage test departments and power installation and repair and test engineering units.
