Document Type and Number:
WIPO Patent Application WO/2017/101530
Kind Code:
A1
Abstract:
A capacitive voltage transformer comprising a capacitive voltage divider and an electromagnetic unit (C) coaxially connected in series. The capacitive voltage divider is constituted by connecting in series a top pressure-equalizing cover (A) and three coaxial capacitors (B) connected in series. The electromagnetic unit (C) comprises a compensation reactor, an intermediate transformer, and a speed-saturation and damping reactor. The three coaxial capacitors (B) are provided in an outward sequence with: a main capacitor (1), an inner-layer shielding auxiliary capacitor (5), an inner-layer annular shielded electrode (4), an outer-layer shielding auxiliary capacitor (3), a composite insulation sleeve cylinder (7), and an outer-layer annular shielded electrode (2).
