Abstract
The utility model relates to a vacuum contactor with an alternating current magnetic circuit structure. The utility model is composed of a vacuum pipe, a transmission mechanism and an alternating current magnetic circuit structure. An electric main contact is sealed in the vacuum pipe. The moving contact of the main contact can do the corresponding motion, and the moving contact of the main contact is provided with an arc-extinguishing component. The alternating current magnetic circuit structure is a silicon steel sheet or a silicon steel sheet being made of an E-shaped or U-shaped iron core and a coil. The utility model is characterized in that an alternating current control power supply is directly connected with the coil, the magnetic force is generated, and the closing motionof the utility model is completed. The transmission mechanism is composed of an armature iron, a reaction spring, a support rod and a connecting rod. The connecting rod is connected with the moving contact. The utility model has simple structure, saves the rectifying device, and reduces the failure rate of the control loop.
Description
The utility model belongs to the electric switch technical field.
Present vacuum contactor is sealed in electric main contact in the vacuum tube, so main contact is in deciliter process, and no arcing has been eliminated the adverse effect of sound light and heat, thereby has increased the life-span and the security performance of electrical contact.But deciliter finishing of present this vacuum contactor by the dc circuit magnetic loop structure, the auxiliary switching contact that is provided with so the size variation of rectifying device and adhesive and maintenance energy must be arranged in the ac control circuit etc., so vacuum contactor of dc circuit magnetic loop structure, control is replied assorted, components and parts are many, failure rate is also high, and cost is also higher.
The purpose of this utility model provides a kind of vacuum contactor of AC magnetism line structure, has simplified control loop, reduces components and parts, reduces failure rate and reduces cost.
The utility model is made up of vacuum tube, transmission mechanism, iron-core coil and framework; Electric main contact is sealed in the vacuum tube.And the moving contact of main contact can do relative motion and the arc extinguishing member is arranged, and two electrical connectors of main contact expose outside the vacuum tube.Transmission mechanism is made up of armature, support bar, connecting rod and reaction spring, and when not producing magnetic force, because the reaction spring effect, armature and iron core opening part keep the working clearance, and the electric main contact in the vacuum tube is in off-state simultaneously.Armature connects support bar, and support bar connects connecting rod, and connecting rod connects the moving contact in the electric main contact in the vacuum tube.Iron core is by silicon steel sheet or folded thick the forming of silicon steel sheet, and its shape has " E " shape and " U " shape.Coil is on the hollow sleeve pipe, be enclosed within then on the leg of iron core, coil two is connected with AC power (380v or 220v) by starting knob, and AC power produces magnetic force suction moving armature armature by coil and affects support bar, connecting rod, makes the main contact closure in the vacuum tube.Described armature movement has clapper-type, and fixed pivot (axle) is promptly arranged, and is that circular motion is done in the axle center with this fulcrum during work, the armature structure of Direct Action Type and helix tube type is arranged, all straight motions when they work.This AC magnetism line structure can divide the main contact of unification vacuum tube, main contact that also can synchronous deciliter a plurality of vacuum tubes.
Advantage of the present utility model, because directly AC power produces magnetic force by coil and iron core, finish deciliter action of main contact in the vacuum tube, apparent face sees that easily its control loop simplified, economized rectifying device, do not needed auxiliary switching contact simultaneously, thereby make the vacuum contactor structure simpler, reduce the failure rate of control loop, also reduced cost.
