Abstract

The invention discloses a novel vacuum tube. The novel vacuum tube comprises a porcelain cylinder, wherein a movable end cover plate is fixedly connected with an inner-side wall of the bottom of the porcelain cylinder, a movable conductive rod is connected to the movable end cover plate in a sliding way, a sliding opening is formed in the top of the movable end cover plate and is corresponding tothe movable conductive rod, and a support mechanism is fixedly connected with an outer-side wall of the conductive rod. In the novel vacuum tube, the top of a corrugated tube is connected with a limitation ring by a plurality of balls under a matching effect of the first balls, the limitation ring, second balls, the corrugated tube, the movable conductive rod and the movable end cover plate, the bottom of the corrugated tube is connected with the movable end cover plate by a plurality of second balls, the corrugated tube is driven to simultaneously rotate by the movable conductive rod, and thefunction of preventing the movable conductive rod from rotating to cause excessively large torque of the corrugated tube is achieved; and by a matching effect of the porcelain cylinder and a siliconrubber layer, the effect that the silicon rubber layer wraps an outer surface of the porcelain cylinder is achieved, and the function that an external insulation layer of a vacuum arc tube is easily broken down by a high voltage.

Description

technical field [0001] The invention relates to the technical field of vacuum tubes, in particular to a novel vacuum tube. Background technique [0002] Vacuum tubes, also known as vacuum switching tubes, are the core components of medium and high voltage power switches. The excellent insulation of the vacuum inside the tube enables the medium and high voltage circuits to quickly extinguish the arc and suppress the current after the power supply is cut off, so as to avoid accidents and accidents. [0003] The current vacuum tube will be installed on the positive electrode during use, and the torque of the bellows will be too large due to the twisting of the conductive rod, resulting in reduced service life of the vacuum tube or air leakage failure. Contents of the invention [0004] The purpose of the present invention is to solve the problem of excessive torque of the bellows in the prior art, and propose a new type of vacuum tube. [0005] In order to achieve the above...
