Problems solved by technology

The oil-filled pure porcelain casing has the advantages of simple manufacture and cheap price, but due to its material problems, it has problems such as heavy weight, fear of bumping, fear of contamination, and easy leakage; while oil-paper capacitors and gel capacitors are dry. Due to the introduction of capacitor voltage dividing bushing, the electric field of the bushing is more uniform and the level of safe operation is relatively improved. However, due to the introduction of capacitors, it has problems such as complicated manufacturing process, high price, and heavy weight. Therefore, there are It is necessary to improve the existing oil-filled pure porcelain bushing to better meet the needs of actual use

Abstract

The invention relates to a low-voltage bushing, in particular to a non-winding non-capacitive composite insulating bushing, which sequentially includes a metal guide rod (11) and an insulating skeleton (9) from the inside to the outside. The insulating skeleton (9) The upper part of the outer side is provided with an organic composite shed (8), and the lower part is provided with a metal flange (10), and the lower edge of the organic composite shed (8) partially covers the outer side of the upper edge of the metal flange (10) The lower end of the metal guide rod (11) is provided with a lower tray (13) extending outwards for positioning the insulating frame (9), the outer diameter of the lower tray (13) and the bottom of the insulating frame (9) Features such as being fixedly connected to each other by insulating pins (12). The function of the invention is: the casing is light in weight, not afraid of bumping, and has excellent anti-pollution flashover level; it has extremely high mechanical strength and mechanical shock resistance; the electric field at the oil end of the casing is more uniform, which greatly reduces risk of terminal flashover.

Description

technical field [0001] The invention relates to a low-voltage bushing, in particular to a non-winding non-capacitance composite insulating bushing. Background technique [0002] The low-voltage bushings currently in use mainly include the following categories: oil-filled pure porcelain bushings, grease capacitor bushings and capacitor dry bushings. The oil-filled pure porcelain casing has the advantages of simple manufacture and cheap price, but due to its material problems, it has problems such as heavy weight, fear of bumping, fear of contamination, and easy leakage; while oil-paper capacitors and gel capacitors are dry. Due to the introduction of capacitor voltage dividing bushing, the electric field of the bushing is more uniform and the level of safe operation is relatively improved. However, due to the introduction of capacitors, it has problems such as complicated manufacturing process, high price, and heavy weight. Therefore, there are It is necessary to improve the...
