Title:
LARGE-CAPACITANCE INSULATION CORE BODY, HIGH-VOLTAGE ELECTRICAL APPARATUS AND MULTI-FUNCTIONAL HIGH-VOLTAGE BUSHING
Document Type and Number:
WIPO Patent Application WO/2017/148159
Kind Code:
A1
Abstract:
A large-capacitance insulation core body, in which a capacitance increasing structure (10) is provided. The capacitance increasing structure (10) is a plurality of capacitive screen groups composed of forward capacitive screen groups (11) and reverse capacitive screen groups (12) which are arranged alternately and connected in parallel. The forward capacitive screen groups (11) comprise a plurality of capacitive screens which are arranged alternately with insulation layers, wherein the innermost capacitive screen of the forward capacitive screen groups (11) is connected to a high potential, and the outermost capacitive screen is connected to a low potential. The reverse capacitive screen groups (12) comprise a plurality of capacitive screens which are arranged alternately with insulation layers, wherein the innermost capacitive screen of the reverse capacitive screen groups (12) is connected to a low potential, and the outermost capacitive screen is connected to a high potential. The innermost capacitive screen group and the outermost capacitive screen group of the plurality of capacitive screen groups of the capacitance increasing structure (10) are both forward capacitive screen groups (11). The insulation core body can be applied to a high-voltage electrical apparatus and a multi-functional high-voltage bushing, and the requirements for voltage equalization and large-capacitance are satisfied at the same time.
