    Abstract: The present invention provides a capacitive voltage transformer, including: a capacitive voltage-dividing component and an electromagnetic unit. The capacitive voltage-dividing component comprises: one or more levels of stacks, and each stack is a coupling capacitor. The coupling capacitor includes: an upper cover plate, a lower cover plate, an insulating sleeve, a capacitor core, squirrel cage electrodes, volume matching devices, a high voltage lead, and a low voltage lead. The lowermost coupling capacitor is provided with a medium voltage lead and a lead terminal. The low voltage lead of the lowermost coupling capacitor is led out through a low-voltage leading-out tube arranged in the lead terminal, and the medium voltage lead of the lowermost coupling capacitor is led out through a medium-voltage leading-out post arranged in the lead terminal. The medium-voltage leading-out post passes through and out of the low-voltage leading-out tube and is arranged coaxially with the low-voltage leading-out tube.

    Abstract: Disclosed is a high-voltage AC capacitor for reactive power compensation of 10 kV-35 kV power grid, and in particular to a high-voltage AC capacitor with a high-voltage switching switch provided therein, as well as a structure for prolonging the service life of a thin film metalized high-voltage capacitor and a control method for prolonging the service life of the thin film metalized high-voltage capacitor. The AC capacitor is formed by multiple intelligent switch capacitor units connected in series, and each capacitor unit is formed by a switch contact (K11-Kn1) and a capacitor (C1-Cn) connected in series. If there are N capacitor units, when each switch contact is disconnected, the endurable voltage of each switch contact, the endurable voltage between the switch contact and a coil and the voltage each capacitor withstands are 1/Nth of the total voltage; when the switch operates, all the contacts operate at the same instant.
