Abstract
The utility model discloses a kind of Novel welding apparatus D.C. contactor, primarily of base plate, connect line end, antagonistic spring, iron core, coil, armature, fixed contact, moving contact and elastic rod composition, described base plate upper left side is provided with connection line end, the base plate upper right corner is provided with fixed contact, on base plate, centre position, right side is provided with iron core, iron core is provided with coil, armature is provided with on the right of iron core, armature is arranged on elastic rod, elastic rod is provided with moving contact on the left of upper end, and base plate upper and lower is provided with antagonistic spring and is connected with elastic rod.The utility model, simply small and exquisite, simultaneously without arc extinguishing circle, low in energy consumption, extend useful life, just they are extinguished before electric arc is connected mutually, greatly improve the reverse make-break capacity of Novel welding apparatus D.C. contactor.
Description
Technical field
The utility model belongs to contactor technical field, is specifically related to a kind of Novel welding apparatus D.C. contactor.
Background technology
At present, on market, existing Novel welding apparatus D.C. contactor is generally made up of arc control device, running part, coil etc., and this type of contactor has the ability of break-make DC load under high voltages.In order to improve the arc extinction performance of this type of contactor, this type of contactor generally have employed the technology of magnetic quenching.Traditional magnetic quenching make use of galvanic directivity, the lateral direction of electric arc toward contactor is blown with magnetic field, makes electric arc elongate and extinguish.But this type of contactor is when oppositely disconnecting, electric arc is expanded in the plane at two places, contact between two contacts, last conducting mutually, causes electric arc not extinguish in time, thus causes the reverse make-break capacity of this Novel welding apparatus D.C. contactor much more weak than the forward break-make life-span.
Utility model content
The purpose of this utility model is to provide a kind of Novel welding apparatus D.C. contactor, to solve the deficiency existed in such scheme.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of Novel welding apparatus D.C. contactor, primarily of base plate, connect line end, antagonistic spring, iron core, coil, armature, fixed contact, moving contact and elastic rod composition, described base plate upper left side is provided with connection line end, the base plate upper right corner is provided with fixed contact, and on base plate, centre position, right side is provided with iron core, and iron core is provided with coil, armature is provided with on the right of iron core, armature is arranged on elastic rod, and elastic rod is provided with moving contact on the left of upper end, and base plate upper and lower is provided with antagonistic spring and is connected with elastic rod.
Connection line end on described base plate is provided with nut and fixes.
Described elastic rod lower right side is provided with auxiliary contact.
The utility model, simply small and exquisite, simultaneously without arc extinguishing circle, low in energy consumption, extend useful life, non-maintaining, reduce the maintenance cost of user.The contact chip of this Novel welding apparatus D.C. contactor between two contacts adds a pottery
Porcelain piece, the length forcing electric arc to be expanded in identical space elongates original 2 ~ 3 times, just they is extinguished, greatly improve the reverse make-break capacity of Novel welding apparatus D.C. contactor before electric arc is connected mutually.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
1-base plate; 2-connects line end; 3-antagonistic spring; 4-iron core; 5-coil; 6-armature; 7-fixed contact; 8-moving contact 9-elastic rod.
Embodiment
