Abstract
The utility model relates to a release in electric shock and leakage protectors. The leakage release is composed of a magnetic clamp, a magnetic yoke, a divided magnetic sheet, an armature and a releasing coil. The leakage release is characterized in that two magnetic yokes in the middle of the magnetic clamp are straight strip-shaped. Thus, the leakage release is more material-saving and has lower manufacture cost than the existing releases.
Description
The utility model relates to a kind of release in the electric shock earth leakage protective device technical field.
At present the release in the electric shock earth leakage protective device is the plate stack slice structure, and its armature, yoke, branch magnetic sheet adopt all that high permeability material--permalloy is made.Its shortcoming is the convex that is shaped as of yoke, and when adhesive, the magnetic line of force divides magnetic sheet to constitute the loop from top armature, and yoke horizontal component two ends are unnecessary in fact, and promptly horizontal two ends are provided with the magnetic line of force and pass through.Therefore, this shape causes very big waste of material in making release.
The utility model purpose and task are to provide new a kind of release with material for what reduce the critical piece yoke in the release manufacturing and divide magnetic sheet.
The technical scheme of finishing the utility model purpose and task is still laminated structure, and wherein two yokes are to adopt the vertical bar shape, also can reduce width accordingly with the time-division magnetic sheet.
This novel tangible advantage of release is the material of using of having saved yoke and having divided magnetic sheet, reduces manufacturing cost, and there is the different economic benefit of showing in manufacturing enterprise.
Now according to the detailed explanation of drawings and Examples technology contents of the present utility model.
Fig. 1 is the utility model structure chart.
The shape of yoke 4 is as shown in Figure 1: be the vertical bar type.In manufacturing process, adopt the plate stack slice structure: put two yokes 4 on 1 on two magnetic folder, between two yokes 4, place a branch magnetic sheet 5, they fix tightlies that superposes, be nested with tripping coil 2 with screw, armature 3 arranged two yoke 4 upper ends on the top of a slice yoke 4.Just often, armature 3 and yoke 4 adhesives.When circuit has electric leakage, the zero sequence current mutual inductor current signal input release tripping coil 2 of Electrical leakage makes armature 3, yoke 4, divides magnetic sheet 5, yoke 4, armature 3 loop magnetic fluxs, reaches residual operating current at leakage current, armature breaks away from yoke, release release movement.
Claims (1)
1, a kind of release includes magnetic folder 1, yoke 4, divides magnetic sheet (5), armature (3) and tripping coil (2), it is characterized in that two yokes (4) between two magnetic folders (1) are vertical bar shapeds.
