Abstract
The utility model discloses an indoor high-voltage load switch. The indoor high-voltage load switch comprises a base, wherein three tiers of insulators are arranged on the base; each tier of insulators comprises two insulators; the two insulators are arranged at the front part and the middle part of the base respectively; a static contact is arranged on the front insulator; a moveable contact is arranged on the middle insulator; an arc extinguishing device is arranged on the static contact; a blade is arranged between the moveable contact and the static contact; a knife board is arranged on the blade; the front end of the knife board is positioned inside the arc extinguishing device; the middle part of the knife board is rotatably connected with the blade through a supporting plate; the back end of the knife board is slidably arranged on the blade; the back end of the knife board is connected with a pull rod mechanism; and the pull rod mechanism acts to control the back end of the knife board to slide in the blade back and forth to make the knife board rotate around the supporting plate, so as to control the front end of the knife board to ascend and descend to open and close the switch. The indoor high-voltage load switch is simple in structure and high in opening and closing speeds.
Description
Technical field
The utility model relates to on-load switch.
Background technology
The patent No. is that 99244046.7 Chinese utility model patent discloses a kind of high voltage load switch, two row's insulator upper ends, front and back of installing on underframe are installed arc-control device and arc knife system respectively, U type magnetic conductive board is housed on the arc control device in the arc-control device, insulated column is housed in the arc control device, and the arc knife system is to be made of by bearing pin and the auxilliary cutter of torsion spring dress operator.Its complex structure, the separating brake closing speed is fast inadequately.
The utility model content
Technical problem to be solved in the utility model just provides a kind of simple in structure, indoor high-voltage on-load switch that the separating brake closing speed is fast.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the indoor high-voltage on-load switch, comprise base, it is characterized in that: described base is provided with three row insulators, every row insulator comprises two insulators, two insulators are located at base front portion and middle part respectively, on the anterior insulator fixed contact is installed, on the insulator of middle part moving contact is installed, described fixed contact is provided with arc-control device, be provided with a blade between described moving contact and described fixed contact, described blade is provided with a knife plate, described knife plate front end is positioned at arc-control device, described knife plate middle part is connected with described blade rotation by supporting bracket, the slip of described knife plate rear end is located on the described blade, described knife plate rear end cylinder lever connecting rod mechanism, thus the front and back slip in blade of drag link mechanism action control knife plate rear end makes knife plate center on supporting bracket rotation control knife plate front end lifting and fall realization switch separating brake and combined floodgate.
Preferably, described drag link mechanism comprises the control lever that traverses described base plate, and each knife plate rear end connects a pull bar, and the front end of a back end of tie rod and a connecting rod is rotationally connected, and rod rear end and control lever are fixed, and control lever rotation control link, pull bar, knife plate move successively.
Preferably, described base also is provided with an insulator at every row insulator rear portion, and described insulator is provided with connecting plate, is connected the high pressure fusion tube between described connecting plate and described contact.Combine on-load switch and fuse advantage separately, cut-off any load electric current,, play the function of short-circuit protection again by fuse up to its specified drop-out current by on-load switch.
The utility model rotates control link, pull bar, knife plate by control lever and moves successively, thereby slides before and after in blade and make knife plate center on supporting bracket to rotate control knife plate front end lifting and fall to realizing switch separating brake and combined floodgate in the knife plate rear end.Material is the high temperature gas exhausted material in the arc-control device, during separating brake, when running into the high temperature that produces by electric arc, material surface will gasify, and produce a large amount of gases in moment, and accumulate at short notice in the arc control device narrow space, produce very big air pressure, played effective arc extinguishing effect, i.e. aerogenesis arc extinguishing, simple in structure, the separating brake closing speed is fast.
