Abstract
The utility model relates to a control switch, and particularly relates to a load isolating switch. The load isolating switch mainly solves the technical problems that in the prior art, the existing load switch is used in a middle-high voltage circuit, and high-energy arc can be produced when the circuit is cut off because of larger current, thus the device becomes very dangerous. The control switch provided by the utility model comprises a base (1), and is characterized in that the base (1) is internally provided with an arc extinguishing chamber (2), the arc extinguish chamber is internally provided with an arc extinguishing plate (3), the arc extinguishing chamber (2) is further internally provided with a static contact (4) and a movable contact (5) in a symmetrical mode, the movable contact is connected with a rotatable handle (7) by a transmission piece (6), and the static contact and the movable contact are both connected with a spring piece (8).
Description
Technical field
The utility model relates to a kind of control switch, especially relates to a kind of isolation on-load switch.
Background technology
At present; Isolating switch is the simplest and more a kind of again control switch of use of structure in the manual electrical equipment; It is mainly used in not connects with the little low-voltage circuit of breaking capacity continually or directly starts small-capacity motor, its in circuit mainly role be: safety and the disjunction load of insulating power supply to guarantee circuit and maintenance of equipment.Chinese patent disclose a kind of vacuum insulation on-load switch the arc control device branch, close mechanism's (Granted publication number: CN2671110); It comprises a shell; By the bracket that isolation knife roller combined floodgate thrust and separating brake thrust promote, realize the tripping spring and the moved end guide rod of arc control device branch, combined floodgate, guide rod is provided with excess of stroke spring; It is characterized in that described bracket is connected with the cam drive that is located at the shell aperture end; Receive the cam rotary lifting to make counter-rotational buckle, buckle is hinged and connected with the little axle that is supported on shell, and the effect of being buckled in mutually has on the semiaxis of torsion spring; Described moved end guide rod is made up of the top guide bar and the lower guide rod of mutual coaxial installation and flexible connection; Flexibly connect with buckle again simultaneously; Rotated by buckle and move up and down, and buckle is not held to be pressed on and is located on the coaxial mounted tripping spring of going up on screw rod and the following screw rod; The buckle end is pressed on the tripping spring through the roller that bearing pin connected that is located in the screw rod oblong slots; Top guide bar and lower guide rod flexibly connect through the oblong slots that is connected bearing pin and top guide bar on the lower guide rod; Excess of stroke spring is the dish spring.But this on-load switch is used in the mesohigh circuit, because electric current is bigger, in disjunction, can produces high-octane electric arc, thereby equipment is had very big danger.
The utility model content
The utility model provides a kind of isolation on-load switch; It mainly is to solve the existing in prior technology on-load switch to be used in the mesohigh circuit; Because electric current is bigger, in disjunction, can produces high-octane electric arc, thereby equipment is had the technical problem of very big danger etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of isolation on-load switch of the utility model; Comprise pedestal; Be provided with arc control device in the described pedestal, be provided with arc quenching plate in the arc control device, also be arranged with fixed contact and moving contact in the arc control device; Moving contact is connected with rotatable handle through driving member, and fixed contact, moving contact all are connected with spring leaf.Behind the turning handle,, can make the moving contact move left and right, when moving contact and fixed contact carry out contacting, be "on" position through driving member.Spring leaf can reset moving contact.The two ends of pedestal can connect input terminal and outlet terminal, and input terminal, outlet terminal are communicated with fixed contact, moving contact respectively.
As preferably, described handle is connected with retainer spring, and retainer spring is located in the lid, and lid is connected on the pedestal.When handle turned to certain position, retainer spring can be fixed on certain position with handle, prevented the handle revolution of skidding.
As preferably, described driving member connects handle through shaft coupling, connector.Through shaft coupling, connector, make that the assembling of handle is simpler, rotate also more smooth and easy.
Therefore, the utility model is through handle interlock moving contact, contact connection through putting between moving contact and the fixed contact, thereby make that the disjunction of electric current is comparatively simple, and moving contact and fixed contact is located in the arc control device, can not produce danger, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 2 is A-A cross-sectional view of Fig. 1.
Parts, position and numbering among the figure: pedestal 1, arc control device 2, arc quenching plate 3, fixed contact 4, moving contact 5, driving member 6, handle 7, spring leaf 8, retainer spring 9, lid 10, shaft coupling 11, connector 12.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: a kind of isolation on-load switch of this example; Like Fig. 1, Fig. 2, a pedestal 1 is arranged, be provided with arc control device 2 in the pedestal; Be provided with arc quenching plate 3 in the arc control device; Also be arranged with fixed contact 4 and moving contact 5 in the arc control device, moving contact is connected with rotatable handle 7 through driving member 6, and driving member connects handle 7 through shaft coupling 11, connector 12.Handle is connected with retainer spring 9, and retainer spring is located in the lid 10, and lid is connected on the pedestal.Fixed contact, moving contact all are connected with spring leaf 8.
During use, moving contact at first carries out contacting with fixed contact 4, realizes "on" position.Turning handle 7, under the effect of driving member 6, moving contact moves right, and moving contact separates with fixed contact, thereby realizes separating brake.
The above is merely the specific embodiment of the utility model; But the architectural feature of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
