The lower end of the mobile guide rod extends out of the shell of the electromagnetic drive mechanism and is connected with one end of a lever in a hinged way. The other end of the lever is connected with the lower end of the moving contact in the hinged way. The middle part of the lever is fixed between the arc-extinguishing chamber and the shell of the electromagnetic drive mechanism via a supporting hinge. A tension spring is installed between the lever and the shell of the electromagnetic drive mechanism. The electromagnetic drive solid insulating switch has characteristics of being reasonable in design, simple in structure, low in fault rate and long in the service life.
Description
Technical field
The utility model relates to a kind of insulated switch, particularly a kind of Electromagnetic Drive solid insulation switch.
Background technology
At present solid insulation switch is to drive moving contact action in the arc control device by mechanical transmission mechanism, realizes the contact of quiet, moving contact and opens.Because the very complicated transmission mechanism that the mechanical transmission mechanism in the solid insulation switch is comprised of mechanisms such as gear, lever, chains, moving component is many, manufacture process requirement is higher, sliding friction surface is many, in During Process of Long-term Operation, the problems such as inefficacy of the wearing and tearing of part, corrosion and lubricant will cause operate miss, failure rate higher.
Summary of the invention
The purpose of this utility model is to solve the defective that prior art exists, provide a kind of simple in structure, parts are few, the electromagnetic drive type solid insulation switch of dependable performance.
The technical solution of the utility model is: a kind of Electromagnetic Drive solid insulation switch, comprise the insulated switch housing, be installed in the arc control device in the insulated switch shell and drive the driving mechanism that the moving contact in the arc control device moves, it is characterized in that above-mentioned driving mechanism is by the moving leader that is installed in the electromagnetic drive mechanism shell, upper electromagnet on being fixed on the plate-like driving body on the moving leader and being fixed in the electromagnetic drive mechanism shell, the permanent magnet and the lower electromagnet that are fixed on lower end order installation from top to bottom in the electromagnetic drive mechanism shell form, the electromagnetic drive mechanism shell is stretched out in the lower end of moving leader, and hinged with an end of lever, the other end of lever and the lower end of moving contact are hinged, the lever middle part is fixed between arc control device and the electromagnetic drive mechanism shell by supporting hinges, between lever and electromagnetic drive mechanism shell extension spring is installed.
Above-mentioned lever two ends and hinged hole are slotted hole.
Solenoid in the above-mentioned electromagnet links to each other with electric control gear.。
The technical solution of the utility model is to utilize solenoid actuated mechanism to substitute existing mechanical transmission mechanism, because solenoid actuated mechanism has simple in structure, the characteristics such as parts are few, failure rate is low, cooperate permanent magnet and extension spring by electromagnet, drive leverage and drive moving contact action in the arc control device, make solid insulation switch of the present utility model have the characteristics such as reasonable in design, simple in structure, failure rate is low, long service life.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, arc control device 1 are installed in the insulated switch housing, and the upper end in arc control device is equipped with fixed contact 2, and the lower end in arc control device is equipped with the moving contact 4 that matches with fixed contact, quiet, moving contact is installed in the interior radome 3 of arc control device, and arc control device are stretched out in the lower end of moving contact.
Moving leader 9 is installed in electromagnetic drive mechanism shell 13, be fixed with plate-like driving body 12 at the moving leader middle part, upper electromagnet 14 is installed in the upper end in the electromagnetic drive mechanism shell, lower end in the electromagnetic drive mechanism shell, lower permanent magnet 11 and lower electromagnet 10 from top to bottom are installed, and the distance between upper electromagnet and the lower permanent magnet is greater than the thickness of plate-like driving body.The electromagnetic drive mechanism shell is stretched out in the moving leader lower end, and hinged with the right-hand member of lever 6, the lever middle part is fixed between arc control device and the electromagnetic drive mechanism shell by supporting hinges 7, the left end of lever and the lower end of moving contact are hinged, between lever right side and electromagnetic drive mechanism shell extension spring 8 are installed.For guaranteeing that moving leader and moving contact are in plumbness, lever two ends and hinged hole 5 are slotted hole during lever swing.
During use, when needing quiet, the moving contact contact of solid insulation switch, lower electromagnet energising, the plate-like driving body moves down in the effect of the electromagnetic attraction of lower electromagnet, to the plate-like driving body with after lower permanent magnet contacts, the lower electromagnet outage, the plate-like driving body is attracted on the lower permanent magnet, and moving leader moves down simultaneously, drives lever and clockwise rotates, the promotion moving contact moves up and contacts with fixed contact, and solid insulation switch is closed.Extension spring this moment is stretched, and the pulling force of extension spring is less than the magnetic force of permanent magnet.
When needs disconnect solid insulation switch, upper electromagnet 14 energisings, the plate-like driving body moves up in the effect of the electromagnetic attraction of upper electromagnet, moving leader drives lever and rotates counterclockwise, the promotion moving contact moves down with fixed contact and disengages, solid insulation switch disconnects, upper electromagnet outage, and lever makes moving contact and fixed contact be in disengaged position under the pulling force effect of extension spring.
The switching electricity of electromagnet is to control by electric control gear.
