Description
Technical field
The utility model belongs to Low Voltage Electrical Apparatus, particularly a kind of calibration structure of thermal overload relay dropout distance.
Background technology
Thermal overload relay, common and A.C. contactor collocation is applied in the thermal overload protection of motor.Motor, in actual motion, as drags manufacturing machine and carries out in the course of work, if abnormal situation or circuit abnormality appear in machinery, makes motor run into overload, and motor speed declines, the electric current in winding will increase, and makes the winding temperature rising of motor.If the overload current time little and overload is shorter, motor winding is no more than permission temperature rise, and this overload allows.If but overload time is long, overload current is large, the temperature rise of motor winding will surpass permissible value, makes motor winding aging, shortens the serviceable life of motor, when serious, even can make motor winding.So this overload is that motor can not bear.Electrothermal relay is exactly the thermal effect principle of utilizing electric current, cuts off motor circuit when there is the overload that motor can not bear, for motor provides the protective device of overload protection.
The performance of thermal overload relay and quality depend on the stability of the action of threading off, and dropout action stability is mainly reflected in product action dropout before apart from whether stable.Because mechanical thermal overload relay is to utilize the flexural deformation of bimetallic strip when the thermal overload to trigger trip gear to thread off, bimetallic strip arrives after recovery deformation at Bending Deformation repeatedly, even if the thermal treatment of two gold is done fully again, the reference position of bimetallic strip still can depart to some extent, dropout change of distance, cause product occur misoperation or be failure to actuate, thereby affect properties of product.
At present, in thermal overload relay industry, conventionally adopt the mode that heat is adjusted thermal overload relay to be carried out to the adjusting of setting current size shelves.By connecting drop-away current, coordinate auxiliary two gold shell nail and adjusting head to find the accurate location of the size shelves place scale mark of thermal overload relay, just put into afterwards finished product district; When the product of having debugged is inspected by random samples after placement a period of time, if find, product has underproof, for example bimetallic strip generation drift, just product is placed on heat tune experiment table and again debugs and find new setting current size shelves, even some need to be taken product completely apart and readjust bimetal position.Calibration qualification rate and calibration efficiency are all undesirable.Like this, not only affect the capability and performance of thermal overload relay, also affect the serviceable life of motor.And, by regulating auxiliary two gold shell to follow closely to find big or small setting current gear, be after two golden deformation is stable, rotation by governor motion makes product occur to thread off, and thermal overload relay is when reality is used, bending by the two gold lever that promotes to thread off makes product occur to thread off, above-mentioned governor motion is static, visible, in above-mentioned calibration process, do not conform to the course of action of the actual dropout of thermal overload relay, cause certain calibration deviation, finally cause the effect of thermal overload relay unstable.

In addition, in order to realize thermal overload relay, realize the tripping function of different overload currents, described pedestal 2 is provided with for regulating the adjusting head 6 of setting current gear, because above-mentioned adjusting head 6 regulates structure and the regulative mode of electric current gear, are all common structures of this area, the utility model no longer describes in detail.
Adopted the thermal overload relay of above-mentioned calibration structure, the calibration steps of its dropout distance, comprises the following steps,
(1). keep described housing 1 fixing, regulate described regulating part 3, it in the present embodiment, is set screw, after making described dropout lever 21 spaced apart with described differential lever 13, thermal overload relay is connected to drop-away current, after described bimetallic strip 11 stabilizations, rotate set screw and make described dropout lever 21 approach described differential lever 13, until mechanical unlocking action; Pointer T1 in described set screw is now aimed on the position of described housing 1 and be labeled as " energize to trip position ", be i.e. mark A in (a) view of Fig. 3;
(2). turn-off current, treat that thermal overload relay is completely cooling, rotate set screw and make described dropout lever 21 approach described differential lever 13, until mechanical unlocking action; Pointer T1 in described set screw is now aimed on the position of described housing 1 and be labeled as " power-off thread off position "; Be the mark B in (b) view of Fig. 3;
(3). rotate described set screw, make pointer T1 on it be aligned to " energize to trip position A " and locate, " power-off thread off a position B " described in the alignment of set screw now located to be labeled as " collimating marks ", i.e. mark T2 in (c) view of Fig. 3; Now, in described set screw, original described pointer T1 is " the equivalence dropout distance " of described thermal overload relay with the angle of spread of described " the collimating marks T2 " of new mark; Be that the initial position of the interior differential lever 13 of housing 1 is to the distance of dropout position.
(4). described bimetallic strip 11 occurs after zero point drift, and turn-off current, after thermal overload relay is completely cooling, rotates described set screw and makes described dropout lever 21 approach described differential lever 13, until mechanical unlocking action; The housing 1 at the place, pointer place of described set screw is now labeled as to the mark B ' in (d) view that " zero point drift power-off dropout position " is Fig. 3, then, rotate described set screw, make described " collimating marks T2 " aim at described " a zero point drift power-off dropout position B ' ", the distance of threading off has just completed calibration.
After step (4), by described lock-screw 5 lockings, make described housing 1 and described pedestal 2 realize constraint fixing.
The described drop-away current of step 1 is corresponding with the setting current shelves of described adjusting head 6; Now, between step (1) and step (2), increase step (1.1): adjusting head 6 is threaded to the described setting current shelves corresponding with described drop-away current.
Obviously, above-described embodiment is only for example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And among the protection domain that the apparent variation of being extended out thus or change are still created in the utility model.
