The invention provides an improved vacuum switch, comprising an insulating shell, a vacuum detection bag structure, an adsorbable mounting disk structure, a removable heat dissipation seat structure,a movable end cover, a static end cover, a static conductive rod, a static contact, a movable contact, a spring, a sleeve block, a shielding cover, a connecting block, a connecting column, a step, a bellows and a movable conductive rod. As a fix seat, the slide groove, the splint, the condensing fin, the liquid injection pipe and the pipe plug are arranged, the heat dissipation effect of the vacuum switch is improved, and the over-high temperature is avoid; The suction cup, the connecting seat and the circular through hole are arranged so as to facilitate the installation of the vacuum switch;The vacuum bag, the connecting pipe, the closing head, the mounting pipe and the sleeve are arranged so as to be convenient for judging whether the vacuum switch leaks or not.
Description
technical field [0001] The invention belongs to the technical field of electrical components, in particular to an improved vacuum switch. Background technique [0002] Vacuum switching tube, also known as vacuum interrupter, through the excellent insulation of the vacuum inside the tube, the medium and high voltage circuits can quickly extinguish the arc and suppress the current after the power supply is cut off, so as to avoid accidents and accidents. It has the advantages of energy saving, material saving, fireproof, explosion-proof, small size, long life, low maintenance cost, reliable operation and no pollution. The conduction of the existing vacuum switch structure is to use the movable contact to contact the static contact, but the contact The excessive contact momentum between the point and the contact point and the contact point and the conductive rod will easily lead to the deformation of the contact point. In view of the above-mentioned problems, the present inven...
