Title:
ANTI-INTERFERENCE STRUCTURE OF CAPACITIVE VOLTAGE-DIVIDING INSULATING CORE BODY, HIGH-VOLTAGE ELECTRIC APPLIANCE, AND ISOLATING SWITCH
Document Type and Number:
WIPO Patent Application WO/2024/060993
Kind Code:
A1
Abstract:
The present invention relates to an anti-interference structure of a capacitive voltage-dividing insulating core body, and a high-voltage electric appliance and an isolating switch using the insulating core body. The capacitive voltage-dividing insulating core body comprises a plurality of voltage-sharing capacitive screens which are arranged in a first insulating core body and alternate with insulating layers in a surrounding manner; the plurality of voltage-sharing capacitive screens form a voltage-sharing capacitor; the voltage-sharing capacitor and a voltage-dividing capacitor are connected in series to form a capacitive voltage divider; a plurality of shielding capacitive screens which alternate with the insulating layers surround at least some of the voltage-sharing capacitive screens; and the plurality of shielding capacitive screens form a shielding anti-interference capacitor. In the radial direction of the first insulating core body, the distance between the shielding capacitive screen located on the outer side and the voltage-sharing capacitive screen that the shielding capacitive screen correspondingly surrounds is greater than the distance between the shielding capacitive screen located on the inner side and the voltage-sharing capacitive screen that the shielding capacitive screen correspondingly surrounds, such that the impact of the shielding capacitive screens absorbing interference signals on the voltage-sharing capacitive screens can be reduced, and external interference signals are eliminated, thereby improving the precision of collected signals.
