Problems solved by technology

However, installing the metal shielding electrode in the insulating sleeve will increase the product size, and if the metal shielding electrode is not installed correctly during the installation process, it may lead to a decrease in the electrical strength of the insulating sleeve, resulting in a lower product yield
Therefore, by installing a metal shielding electrode at the bottom of the insulating sleeve to solve the problem of electric field concentration at the sharp corner of the adhesive groove, it will not only increase the size of the product, but also increase the difficulty of the process

Abstract

The invention discloses an insulating sleeve and a manufacturing method thereof. The insulating sleeve comprises an insulating tube, two flanges and a conducting rod, wherein the two flanges comprisea high-voltage end flange and a low-voltage end flange which respectively fixedly sleeve the two ends of the insulating tube; and the conducting rod is fixedly connected with the high-voltage end flange and is inserted into the insulating tube; and at least one angle, close to the end portion of the high-voltage end flange, of the low-voltage end flange is an arc angle. In this way, the low-voltage end flange is uniform in distribution of the intensity of an electric field with no need for arrangement of a metal shielding electrode to simplify the structure of the insulating sleeve, reduce thesize of the product and reduce the process difficulty.

Description

technical field [0001] The present application relates to the technical field of electric equipment, in particular to an insulating sleeve and a manufacturing method thereof. Background technique [0002] Insulating bushings are important components in power systems. At present, the flange and the insulating tube in the insulating bushing are usually fixed by a glue-fitting process. Specifically, multiple adhesive grooves are generally opened on the inner wall of the flange and the outer wall of the insulating tube, and epoxy resin glue is injected into the grooves through the glue injection hole of the flange, and then it can be cured at high temperature. However, in actual engineering, the low-voltage end flange is generally grounded to maintain zero potential. Therefore, the electric field intensity at the sharp corner of the adhesive groove inside the low-voltage end flange is very high, and the field intensity distribution is uneven. [0003] In view of this, in the ...
