Abstract
The utility model discloses a control and contact system for protection switch belongs to electrical equipment technical field, and it is unreasonable to have solved traditional contact system structural design, the scarce looks phenomenon of easy production, the problem that mechanism's strength requirement is high, main including the static contact, with corresponding moving contact and the moving contact guide arm of static contact, the moving contact is fixed to be set up on the moving contact guide arm, the utility model discloses a three group's moving contacts are fixed on same contact guide arm among the contact system, and the emergence of scarce looks phenomenon has effectively been avoided in closed and disconnection when organizing the contact by actuation electromagnetism band iron moving contact guide arm completion no. 3, have also reduced the actuation power requirement of actuation electro -magnet, and the energy consumption obtains the reduction, the utility model discloses practical value is very high, has fine market perspective, but wide application in industry, commerce and civilian installations field.
Description
Technical field
The utility model belongs to technical field of electric equipment, specifically, particularly relates to a kind of control and protective switch contact system.
Background technology
Control and protective switch is a kind of intelligent device for switching functions such as short-circuiting device, contactor, thermal relay rolled into one; be mainly used in the occasion needing to protect motor, major function has: short-circuit protection, open phase protection, rotation-clogging protection, overcurrent protection, overvoltage/undervoltage protection and earth leakage protective.Contact system is one of vitals of control and protective switch; three groups of contacts of conventional contact system are self-movements; during adhesive, three groups of moving contacts contact with fixed contact by the stage clip promotion moving contact of self respectively; if wherein there is one group of contact motion to block; switch phase shortage will be caused, protected load is damaged.When contact disconnects, the retracting spring of electromagnet or the energy-stored spring of mechanism will overcome the resistance of three groups of contact stage clips simultaneously by three groups of contact pressures, this just requires that the power of the retracting spring of electromagnet and the energy-stored spring of mechanism will much larger than the summation of the power of three groups of contact stage clips, and guarantee contact reliably disconnects rapidly.Power and the energy consumption of the larger electromagnet of power of the retracting spring of electromagnet and the energy-stored spring of mechanism are larger, also higher to the requirement of strength of mechanism.
Summary of the invention
The utility model discloses a kind of control and protective switch contact system, unreasonable for solving conventional contact system structure design, easily produce phase shortage phenomenon, high problem is required to laser intensity.
The utility model is achieved through the following technical solutions:
A kind of control and protective switch contact system, comprise fixed contact, the moving contact corresponding with fixed contact and moving contact guide rod, described moving contact is fixedly installed on moving contact guide rod.
Described moving contact guide rod is provided with draw-in groove, and described moving contact adopts contact stage clip to be close to plane on draw-in groove.
Described fixed contact is provided with current transformer.
Described fixed contact is divided into a stationary contact head group and No. two stationary contact head groups.
The contact quantity of a described stationary contact head group, No. two stationary contact head groups is respectively three.
Compared with prior art, the beneficial effects of the utility model are:
In contact system of the present utility model, three groups of moving contacts are fixed on same contact guide rod, closed and disconnected while completing three groups of contacts by adhesive electromagnet band moving contact guide rod, effectively prevent the generation of phase shortage phenomenon, also reduce the suction-combining force requirement of adhesive electromagnet, energy consumption is reduced; The utility model practical value is very high, has good market application foreground, can be widely used in industry, business and civilian installation field.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1. moving contact; 2. moving contact guide rod; 3. draw-in groove; 4. contact stage clip; 5. current transformer; 6. a stationary contact head group; 7. No. two stationary contact head groups.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
A kind of control and protective switch contact system, comprise fixed contact, the moving contact 1 corresponding with fixed contact and moving contact guide rod 2, described moving contact 1 is fixedly installed on moving contact guide rod 2.
Described moving contact guide rod 2 is provided with draw-in groove 3, and described moving contact 1 adopts contact stage clip 4 to be close to plane on draw-in groove 3.
Described fixed contact is provided with current transformer 5.
Described fixed contact is divided into a stationary contact head group 6 and No. two stationary contact head groups 7.
The contact quantity of a described stationary contact head group 6, No. two stationary contact head groups 7 is respectively three.
Fixed contact of the present utility model is fixed on the fixed support of switch, moving contact guide rod 2 is connected with the fault disjunction mechanism of switch, when moving contact guide rod 2 moves up and down, drive moving contact 1 to move up and down, thus realize closing and conjunction between moving contact 1 and fixed contact.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
