Abstract
The utility model relates to an improvement on a releaser which is designed for increasing the stability of the releaser, reducing the impulse power and shortening the production period. The utility model is provided with a magnet yoke, an armature, magnetic steel, a winding, an extension spring and a fixing bracket, wherein the magnet yoke is divided into a left magnet yoke and a right magnet yoke, a magnetic valve sheet is clamped between the two magnet yokes, and the magnetic valve sheet and the two magnet yokes are tightly combined into a whole. The utility model is frequently used in electrical leakage protection switches; compared with the original releaser, the stability of the utility model is greatly increased, the impulse power is reduced by one third, the production period is shortened by fifteen days, and the one-time qualification rate is increased more than 90%.
Description
The utility model relates to the improvement of release.
Traditional release is the magnetic field cancellation type, its unstable properties, and the production cycle is long, has directly influenced with its quality and the output as the earth leakage circuit-breaker of parts.
The purpose of this utility model provides a kind of stability that can improve the release performance, reduces to promote power, shortens the magnetic saturation of production cycle and offsets the mixed type release.
The utility model is that the principle of utilizing magnetic saturation and magnetic field to offset mixing is made.Textural, it and existing release all have yoke, armature, magnet steel, coil, extension spring and fixed mount, and its main difference is to be divided into left yoke and right yoke, accompany the magnet valve sheet in the centre of two yokes and are closely as one mutually.
The utility model can be done following connection: the combination of the magnet valve sheet that left and right yoke is middle with being clipped in two yokes is plugged in the middle part of fixed mount, coil be positioned at the front upper part of yoke and pass left and right yoke, magnet steel is contained in the yoke afterbody, armature flexibly connects above yoke and with yoke, one end of extension spring ties up on the armature, and the other end ties up on the fixed mount.
Operation principle of the present utility model is as follows: under normal circumstances, the direct current flux Φ 1 that produces by magnet steel by the N utmost point through left yoke, armature, right yoke flows to the magnet steel S utmost point, armature and yoke adhesive, but in design, yoke, the maximum permeability μ m 〉=200000 Gausses/oersted of the selected material of armature, and the material maximum permeability μ m 〉=1000 Gausses/oersted of the magnet valve sheet in the middle of two yokes, so, as long as yoke and the tight adhesive of armature, magnetic flux Φ 1 passes through yoke basically, armature is got back to the magnet steel S utmost point, and get back to the magnetic flux of magnet steel by the magnet valve sheet, and only be 1000/200000 theoretically, can ignore.The magnetic circuit of its magnetic flux Φ 1 is seen accompanying drawing 3.Among the figure: left yoke-5 magnet steel-8 armature-6 right yoke-4 coil-2.Under direct current flux Φ 1 effect, yoke, armature overcome return spring power and adhesive.
But when circuit broke down, coil was accepted extraneous signal I
oThe time, coil has been set up I
oThe W magnetic potential promptly produces magnetic flux Φ
o, its direction is determined by the right-hand rule, is supposed Φ
oDirection such as accompanying drawing 4 (token name claims with accompanying drawing 3 among the figure).Among Fig. 4: the yoke left side by I
oThe magnetic flux Φ that W produces
oWith magnet steel direct current flux Φ
1Be in the same way, the magnetic flux density in cross section, the yoke left side increases, but the sectional area above the yoke only is 0.8 (mm) in design
2So, in case I
oWhen W reaches a certain amount of, top, yoke left side B
o=Φ
o/ S, magnetic flux density promptly hastens towards saturation, and magnetic resistance promptly increases greatly, and magnetic flux Φ 1 is cut off, and the magnetic flux Φ on the right of yoke
oAnd Φ
1Direction is opposite, has resisted magnetic flux Φ 1 circulation, and armature is forced to discharge.At this moment, be free air bound exhausted between yoke and the armature, and the permeability of air only is μ m=1, magnetic flux Φ
1All pass the magnet valve sheet, turn back to the S utmost point, shown in dotted line among Fig. 4 number, armature be released into the motive force that earth leakage circuit-breaker is cut off the electricity supply.
Advantage of the present utility model is as follows:, stability improves greatly.Two, promote the original release of power ratio and reduce about 1/3rd.Three, the production cycle shortened about 15 days.Four, disposable qualification rate is brought up to more than 90% by original 60%.Five, small product size is dwindled.
Further specified below in conjunction with the accompanying drawing illustrated embodiment.
Fig. 1 is an organigram of the present utility model;
Fig. 2 is the schematic top plan view after the utility model is removed cover,

oThe direction schematic diagram.
This release as shown in Figure 1, 2, left and right yoke 5,4 clamps magnet valve sheet 3 and mutual spot welding is closely as one, and inserts in fixed mount 1 central authorities, inserts a stator 11 at the yoke rear, and yoke is stabilized on the fixed mount.Coil 2 is at the front upper part of yoke and pass left and right yoke, has a circular magnet steel 8 to be contained in the yoke afterbody, and it is snapped in by a slice spring holddown 9 and closely inhale mutually with the yoke afterbody and connects.A slice armature 6 is arranged above yoke, the preceding end in contact of the front end of armature and yoke, connection is inhaled mutually with the rear end of yoke in the rear end of armature, and is supported on the fixed mount.One end of extension spring 7 ties up to the armature middle part, and the other end ties up to the upside of fixed mount.This spring is exactly the source of the release force of armature.Activity push rod 12 is worn by central authorities at lid 10.
