Description
Technical field
The utility model relates to a kind of debugging apparatus, particularly a kind of debugging apparatus of motor protector dropout action consistency.
Background technology
The operation principle of motor protector is: during the motor energising, the main bimetal leaf of motor protector occurs bending and deformation because the electric current on the motor circuit produces heat, main bimetal leaf is because thereby the guide plate that flexural deformation promotes to be attached thereto moves, and guide plate promotes again auxiliary bimetal leaf and rotates; When passing through the electric current overrate of motor, after the series of displacement conduction, auxiliary bimetal leaf will produce enough large rotation displacement and impel the snap close that is attached thereto to thread off, and then make the outage of motor circuit separating brake, realize the protection to motor.
For motor protector production; whether the dropout action of same product unanimously directly has influence on the qualification rate of this kind product; because the error of auxiliary bimetal leaf, main bimetal leaf and guide plate process and assemble so that there is difference in the dropout stroke of each motor protector, causes motor protector dropout action inconsistent.Therefore, the motor protector production out afterwards needs its dropout stroke is debugged, and keeps strokes with the dropout of guaranteeing like product, and this also is one of most important link in the motor protector batch production process.
For the dropout of guaranteeing the same product is kept strokes; need to regulate the dropout stroke of each motor protector; and the dropout stroke mainly comprises two parts; a part is the displacement that turns an angle and produce after auxiliary bimetal leaf is touched, and another part is that main bimetal leaf promotes the guide plate displacement that guide plate produces.In addition, because the initial position of auxiliary bimetal leaf also has influence on main bimetal leaf and promotes the guide plate displacement that guide plate produces, therefore, also need to regulate fixing initial angle of assisting the adjusting head of bimetal leaf, make auxiliary bimetal leaf be in same initial angle, eliminate the impact of the guide plate displacement that main bimetal leaf promotion guide plate is produced.At present, the debugging motor protector same product method of keeping strokes of threading off mainly contains following three kinds:
1, experience ocular estimate.The experience ocular estimate mainly depends on staff's experience; utilize visual observations to adjust main bimetal leaf, auxiliary bimetal leaf and snap close position; realize same motor protector dropout consistency; but this method obviously will have very high requirement to staff's operating experience; and in order to improve the debugging effect; need multiple reversal polyphony examination, very consuming time, and finally debug effect and still be difficult to guarantee.
2, three-phase synchronous machine debugging method.The method is to suppose first a datum level; then guarantee that by the distance of measuring main bimetal leaf and datum level with the three-phase synchronous machine the main bimetal leaf of same motor protector is in same position; can thread off unanimously with this kind of motor protector of establishing sb's identity; but this adjustment method has been ignored the error that other part process and assemble are brought; such as; the same product is because the problem of auxiliary bimetal leaf processing or assembling; there is certain deviation the position; this obviously can exert an influence to the dropout stroke, but above-mentioned this three-phase synchronous machine debugging method is difficult to eliminate the impact of this respect.Therefore, three-phase synchronous machine debugging method debugging effect is generally not ideal.
3, main bimetal leaf self-operated measuring unit debugging method.Chinese patent literature CN1423293A discloses a kind of adjustment method of using motor protector overlond trip master bimetal leaf position automatic testing equipment.Motor protector overlond trip master bimetal leaf position automatic testing equipment is made of frame, the main bimetal leaf position sensing mechanism, laser micrometer, constant-current source and the controlling organization that are installed on the frame.This kind adjustment method comprises following key step: at first be the deflection of measuring main bimetal leaf, this step need to load overload current, when overload current passed through motor protector, main bimetal leaf temperature distortion calculated main bi-metal plate deformed distance by sensing mechanism and controlling organization; Next is the position of measuring auxiliary bimetal leaf, and this step is actual to be exactly the distance between the auxiliary bimetal leaf position when calculating main bimetal leaf initial position and motor protector dropout; At last, by above-mentioned two steps, obtain the directed long cutting data of guide plate through converting, determine the guide plate cutting position.Each product passes through same debug process, and loading current all keeps identical for every product.
This kind method is because each debugging all needs to redefine the guide plate cutting position, and guide plate can't be unified cutting, so debugging efficiency is low, and the debugging apparatus complex structure that uses, and equipment cost is high, and operating process is also comparatively numerous and diverse, has further affected debugging efficiency.In addition, this kind method is not regulated the adjusting head angle, and therefore, the sensing scale of every product adjusting head that debugging is finished is also inconsistent, causes eliminating auxiliary bimetal leaf main bimetal leaf is promoted the Influence of Displacement that guide plate moves.
In sum, do not have still in the prior art that a kind of efficient is high, cost is low, accuracy is high and debug adjustment method satisfactory for result and debugging apparatus.
The utility model content
For solving the problem that adjustment method of the prior art is undesirable for the conforming debugging effect of same motor protector dropout stroke, precision is lower, efficient is not high, cost is higher, a kind of debugging is effective, accuracy is higher, efficient is high and lower-cost motor protector dropout action consistency debugging apparatus and provide.
