Abstract

The invention discloses an epoxy resin dry type sleeve including an insulator having a tubular hollow center, the outside of the insulator is provided with a metal installing base, the head part of the upper end is provided with an end plate, the top of the end plate is provided with a copper sealing fixed end, the copper sealing fixed end is connected with the leading-out wire joint copper conductor in a tubular hollow tube, and a metal installing base is provided with a ground screen device connected with the outer layer of a capacitive pole plate layer in the insulator. The epoxy resin dry type sleeve uses a cylindrical die and the metal installing base as a sleeve frame, and uses epoxy resin as main insulating materials, and a hollow insulation main body is formed by casting epoxy resin on the die by means of vacuum pressure gelation technology. The epoxy resin dry type sleeve is simple in structure, fewer in raw material types, convenient for batch production quality control, less in local discharging, and high in mechanical strength, and has no oil and burning and explosion hidden troubles.

Description

technical field [0001] The invention relates to the field of components for electric equipment, in particular to an epoxy resin dry bushing. Background technique [0002] The lead-out terminals of liquid-immersed power equipment, also known as bushings or insulators, are essential components of liquid-immersed power equipment. For many years, the lead bushings commonly used in medium and high voltage (such as 66kV-220kV) liquid-immersed power equipment such as transformers and reactors are mostly oil-paper capacitive structures. The inner insulation of this type of bushing is made of high-voltage cable paper and conductive Oil-paper capacitor core composed of metal foil. The conductor of the capacitor core is at the highest potential in the center of the bushing, and the outermost part close to the grounding mounting flange is at the ground potential; the outer part is an umbrella-shaped porcelain sleeve, the transformer oil is placed inside the ceramic sleeve, and the cap...
