Abstract
A large-capacitance insulating core, a high-voltage electrical appliance and a multi-functional high-voltage bushing. The insulating core is internally provided with a capacitance increasing structure. The capacitance increasing structure is a plurality of capacitive screen sets formed by a forward capacitive screen set and a reverse capacitive screen set that are alternatively arranged and in parallel connection. The forward capacitive screen set includes a plurality of capacitive screens arranged alternatively with insulating layers, an innermost capacitive screen of the forward capacitive screen set is connected to a high potential, and an outermost capacitive screen is connected to a low potential. The reverse capacitive screen set includes a plurality of capacitive screens arranged alternatively with insulating layers, an innermost capacitive screen of the reverse capacitive screen set is connected to a low potential, and an outermost capacitive screen is connected to a high potential; and an innermost capacitive screen set and an outermost capacitive screen set in the plurality of capacitive screen sets of the capacitance increasing structure are both the forward capacitive screen sets, and can satisfy the voltage-sharing and large-capacitance requirements simultaneously. The high-voltage electrical appliance and the multi-functional high-voltage bushing include the large-capacitance insulating core.
