Document Type and Number:
WIPO Patent Application WO/2020/199943
Kind Code:
A1
Abstract:
Disclosed is a transformer bushing (1000), comprising: an insulating tube (1010) configured to be of a hollow structure in an axial direction; a capacitor core (1020), comprising a current-carrying rod (1021) running through the insulating tube, and a plurality of insulating layers and a plurality of capacitive screens located in the insulating tube and sequentially wound around an outer side of the current-carrying rod, wherein an end, extending out of the insulating tube, of the current-carrying rod is fixedly connected to a first wiring terminal (1040) and is electrically connected to the first wiring terminal; and an end screen joint (1030) that is electrically connected to an end screen in the capacitor core, and is used for grounding the end screen when the transformer bushing runs. The transformer bushing has a simple structure, such that costs can be saved, the number of production procedures are reduced, and the production efficiency is improved.
