A kind of waterproof rubber device of open-type CT power-taking device

Abstract

The invention discloses a waterproof rubber device of an open type CT power pickup device. The waterproof rubber device comprises a coil, a magnet ring, seal rings, a liner and a shell, wherein the shell is located at the outmost portion of the CT power pickup device, the liner forms an inner ring shell of the CT power pickup device and can hold a wire, the magnet ring serving as the working part of the CT power pickup device is arranged between the shell and the liner, and an outer ring of the magnet ring is provided with the seal rings for protecting the end face of the magnet ring. An existing mature open type CT power pickup magnet ring is used as a basis and has the advantages of being good in protective property, small in size, good in waterproofness and the like. On the basis of not affecting original excellent performance of the CT power pickup magnet ring, the design of the end face seal rings is added, and the service life of power pickup CT is prolonged.

Description

Technical field [0001] The invention relates to a sealing mechanism, in particular to a waterproof rubber device of an open type CT power taking device. Background technique [0002] The existing common open-type CT power taking device structure has no seal ring structure at the magnetic ring engagement surface, or adopts a common O-ring structure without a seal ring structure, and the magnetic ring engagement surface is easy to enter water, which leads to the engagement surface Rust; Ordinary O-ring structure, due to improper meshing and other reasons, will leak or seep in local locations, which will cause the meshing surface to rust, which will damage the meshing degree of the electromagnetic ring, which will affect the efficiency of power extraction and cause magnetic The ring vibrates and generates heat, which affects the life of the CT power-taking device. Summary of the invention [0003] The present invention relates to an open type CT power taking device. At the engagemen...
