Abstract
The utility model discloses a circuit breaker switch, its characterized in that: including the switch bracket, set up a pair of first static contact and the second static contact that uses that pair on the switch bracket, one end and first static contact swivelling joint, the moving contact of the other end and second static contact formation on -off switch, the moving contact passes through drive mechanism and links to each other with operating device the second static contact realizes that one side of break -make is provided with the arc extinguishing bars. The utility model has the advantages of set up the arc extinguishing bars through locating one side at the on -off switch, improved the life of switch.
Description
Technical field
The utility model relates to a kind of electrical control device, particularly a kind of logical disconnecting switch.
Background technology
In ordinary high pressure isolating switch field of switches, although adopting valve tube arc extinguishing effective, but the cost of equipment is too high, and the market competitiveness is not high.
And, existing switch adopts turning axle directly to input the mode of manipulation, causes manipulation moment little, it is desirable to provide bigger power can drive switch, operation inconvenience.
Consequently, it is desirable to existing switch is improved.
Practical novel content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, it is provided that a kind of isolating switch switch.
The technical solution adopted in the utility model is such:
A kind of isolating switch switch, it is characterized in that: comprise switch support, be arranged on switch support one to pairing use the first static contact and the 2nd static contact, one end is rotatably connected with the first static contact, the other end and the 2nd static contact form the dynamic contact of switch on and off, described dynamic contact is connected with operating mechanism by transmission rig, and the side realizing break-make at described 2nd static contact is provided with arc extinguishing grid.
Further, transmission rig is the folding arm that curved rod and cam are formed. Folding arm simplifies actuating mechanism, it is to increase reliability and security.
Further, arc extinguishing grid comprise the first arc quenching plate and the 2nd arc quenching plate, and described first arc quenching plate is arranged on the upper end of the 2nd arc quenching plate, and the opening of described 2nd arc quenching plate is more roomy than the opening of described first arc quenching plate. Different arc quenching plates is for different electric arc, and the first arc quenching plate is for greatly enhancing arc during break-make, and the 2nd arc quenching plate is for the tiny electric arc of diffusion.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, realizing being worked by arc extinguishing during switch contact by the arc quenching plate of little opening, the arc quenching plate of big uncork then for preventing electric arc from spreading, reaches the arc quenching effect of highly effective and safe, it is to increase product work-ing life.

Fig. 1 is isolating switch switch junctions composition.
Fig. 2 is the first arc quenching plate schematic cross-section.
Fig. 3 is the 2nd arc quenching plate schematic cross-section.
Marking in figure: 1 is arc extinguishing frame, and 2 is the first arc quenching plate, and 3 is the 2nd arc quenching plate, 4 is dynamic contact, and 5 is the 2nd static contact, and 6 is the first static contact.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated. It is to be understood that specific embodiment described herein is only in order to explain the utility model, and it is not used in restriction the utility model.
As shown in Figure 1, a kind of isolating switch switch, comprise switch support, be arranged on switch support one to pairing use the first static contact 6 and the 2nd static contact 5, one end is rotatably connected with the first static contact 6, the other end and the 2nd static contact 5 form the dynamic contact 4 of switch on and off, and described dynamic contact 4 is connected with operating mechanism by transmission rig, and the side realizing break-make at described 2nd static contact 5 is provided with arc extinguishing grid. Transmission rig is the folding arm that curved rod and cam are formed. Arc extinguishing grid comprise the first arc quenching plate 2 and the 2nd arc quenching plate 3, and described first arc quenching plate 2 is arranged on the upper end of the 2nd arc quenching plate 3, and the opening of described 2nd arc quenching plate 3 is more roomy than the opening of described first arc quenching plate 3. First arc quenching plate 2 and the 2nd arc quenching plate 3 are arranged on arc extinguishing frame 1 successively.
The useful effect of the present embodiment is: different arc quenching plates is for different electric arc, and the first arc quenching plate 2 is for greatly enhancing arc during break-make, and the 2nd arc quenching plate 3 is for the tiny electric arc of diffusion. Folding arm simplifies actuating mechanism, it is to increase reliability and security.
The foregoing is only better embodiment of the present utility model; not in order to limit the utility model; all any amendment, equivalent replacement and improvement etc. done within spirit of the present utility model and principle, all should be included within protection domain of the present utility model.
