Abstract

The invention discloses an insulator device, which comprises a resin inner core and a rubber layer coated outside the resin inner core, wherein the resin inner core is provided with a middle axis hole; the outer wall of the rubber layer is provided with a plurality of rubber umbrella skirts; the upper end of the resin inner core is provided with a metal binding post; the lower part of the resin inner core is provided with a blocking surface; the outer wall of the resin inner core is provided with screw threads from an open end to a position close to the blocking surface; a sealing ring is arranged close to the blocking surface towards the direction of the screw threads; one side of the sealing ring facing away from the blocking surface is provided with an installation base; one side of the installation base facing away from the sealing ring is provided with a fastening nut; and the fastening nut is used for tightly pressing the installation base against the end face of the sealing ring through the screw threads. According to the insulator device, the technical problems of complex processing process and long production time of an insulator device with high sealing performance in the prior art are solved; and the insulator device has a simple processing process and high sealing performance.

Description

technical field [0001] The invention relates to a high-voltage power electric component, in particular to a high-voltage power capacitor insulator device. Background technique [0002] An insulator is a special insulation control that plays an important role in overhead transmission lines. The high-voltage power capacitor insulators currently used in high-voltage power transmission are generally ceramic components, including an insulator body with multiple sheds, and metal wiring components and metal installation components at both ends of the insulator body. The traditional method of connecting metal wiring components, metal mounting components and the insulator body is generally welding. Due to the particularity of the ceramic material, it is difficult to guarantee the processing accuracy, resulting in different unevenness on the surface of the ceramic material. In order to improve its connection with the metal wiring The sealing of components and metal mounting component...
