Novel embedded pole

Abstract

The invention relates to a novel embedded pole, which comprises a sleeve, a vacuum arc-extinguishing chamber and a silicone rubber-coated insulating locate sleeve, wherein the sleeve is formed by casting epoxy resin; the vacuum arc-extinguishing chamber is arranged in the sleeve; the silicone rubber-coated insulating locate sleeve is arranged between the vacuum arc-extinguishing chamber and the sleeve; a fixed end of the vacuum arc-extinguishing chamber is spirally connected with a copper thread sleeve; a conducting rod is connected to the copper thread sleeve; a sealing ring is arranged between the conducting rod and the sleeve; a POM guide sleeve is supported and fixed at the upper end of the sleeve; a moving end of the vacuum arc-extinguishing chamber is spirally connected with a conductive bus; a spring is arranged between the moving end of the vacuum arc-extinguishing chamber and the conductive bus for playing a resetting function; the conductive bus is guided to carry out vertical motion by the POM guide sleeve; and a drive rod is spirally connected with the top part of the moving end of the vacuum arc-extinguishing chamber. The novel embedded pole is suitable for being installed and used in an SF6 gas-insulated aeration tank; the vacuum arc-extinguishing chamber, the locate sleeve, the copper thread sleeve, the sealing ring and the conducting rod are arranged in the sleeve; and the upper end of the sleeve is provided with a conductive bus structure, so that electric connection of the moving end of the vacuum arc-extinguishing chamber is facilitated; the novel embedded pole is relatively simple in structure; the volume is reduced; the product cost is reduced; the overall installation is facilitated; and the performance is effectively improved.

Description

technical field [0001] The invention relates to power transmission and distribution equipment in a power system, in particular to a novel solid-sealed pole. Background technique [0002] With the development of equipment in the power industry, vacuum technology is relatively mature, and there are new requirements for the reliability and intelligence of power supply. At present, most of the installation and design of vacuum interrupters in SF6 gas-insulated gas-filled cabinets in China are fixed by porcelain columns or insulators. 1. The product is large in size and high in cost. The installation design of this structure is complicated, and its disadvantages are that there are many connecting parts and fixing parts. The insulation performance is easy to age, and there are great hidden dangers, which eventually cause the product to fail the insulation test. [0003] In order to improve product performance, reduce product volume, and reduce product cost, it is necessary to desi...
