Abstract
The utility model relates to an adjustable releasing device for a circuit breaker. A through hole is formed at one lateral edge of an adjustable releasing plate and coaxially arranged with a fixed releasing plate. An adjusting screw is arranged inside the through hole and in an axial sliding connection with the adjustable releasing plate. The distance between the adjusting screw and the fixed releasing plate is in a proportional relation to the rotation distance of the adjusting screw. Since the adjustable releasing device is provided with the adjustable releasing plate, with respect to the different rotational positions of the knob, that is, different rated current values displayed on the panel, the adjustable releasing plate generates different gaps corresponding to the adjusting knob; that is, with respect to the different rated current values, the gap between the adjustable releasing plate and the adjusting knob as well as the gap between the fixed releasing plate and the adjusting knob can be industrially detected and adjusted. During the on-site construction, according to the indicator values displayed on the panel, the adjusting knob is rotated to obtain the desired rated current value without adjusting the adjusting knob. The adjustable releasing device has the advantages of simple and accurate operation and high safety and reliability.
Description
Technical field
The utility model belongs to low depressor field, relates in particular to a kind of adjustable trip gear that is used for circuit breaker.
Background technology
The rated current trip gear of circuit breaker generally is made up of bimetal leaf, dropout plate and adjustment knob.The principle of its delay protection is: when circuit breaker passes through rated current; the bimetal leaf heated bending; because between adjustment knob on the bimetal leaf and the dropout plate enough gaps are arranged; so distortion that heat took place that bimetal leaf produces by rated current for a long time; can not promote the plate of threading off, cause operating mechanism to be threaded off.But after circuit transshipped, electric current rose, and flows through bigger overload current on the circuit breaker, the further heated bending of bimetallic sector-meeting, and through after a while, bimetal leaf is threaded off operating mechanism, and the circuit breaker disjunction realizes the overload protection to circuit.This shows, regulate to adjust the protective effect that knob and the gap between the dropout plate can reach different rated current.In order to reserve enough spaces to adjustment, adjustable dropout plate movably distance all is greater than the needed actual range that is in course of adjustment, and the location of adjustment knob all is also will reserve enough spaces by what the position that is mated on the lid fixed.Will cause inaccurate, the insecure drawback of switch protection value so all be greater than the distance of actual needs from the space that all angles are reserved.Adjustable dropout plate and of mensuration and the adjustment of the gap of adjusting knob by batch production.But in the adjustment process of producing in batches, the adjustment personnel may to be adjusted to the position be not scale value on the panel in order to reach load current value accurately, but but do not have the balance point that to locate, in processes such as carrying, may will rotate to the position that to fix automatically by adjusting knob.And the workmen at the construction field (site) required adjusting have only adjusting knob; the actual current protection value of circuit breaker but is less than this value when the scale value on the adjusting knob aligning panel; will not move when switch reaches the current value that needs protection, cause unnecessary trouble to construction.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of adjustable release that can be adjusted the circuit breaker rated current easily at the construction field (site) by the workmen more exactly is provided
For achieving the above object, the utility model adopts a kind of adjustable trip gear that is used for circuit breaker, comprise bimetal leaf, dropout plate and adjustment knob, adjusting knob is arranged on the bimetal leaf, the dropout plate comprises fixedly dropout plate and adjustable dropout plate, adjustable dropout plate is movably set in fixedly on the dropout plate, adjustable dropout plate forms lozenges towards adjusting knob one side, there is adjustable clearance between lozenges and the adjustment knob, adjustable dropout plate upper surface is provided with one and adjusts knob, be in different positions by the rotation of adjusting knob, lozenges on the adjustable dropout plate has different gaps with adjusting between the knob, offer and the fixing through hole of the coaxial setting of dropout plate at a side of adjustable dropout plate, one adjusts screw is arranged in the through hole and constitutes the axis slippage with adjustable dropout plate and be connected, and adjusts the screw and the fixing proportional relation of rotation distance of distance between the dropout plate and adjustment knob.
The utility model is set to further that the corresponding screw position of adjusting forms belt boss on the through-hole wall of adjustable dropout plate again, adjusts the screw outer wall and is provided with external screw thread, adjusts screw and is threaded with this boss formation.
The adjustable trip gear of circuit breaker rated current of the present utility model is owing to there is the adjustable dropout plate of a slip, with respect to the diverse location of knob, i.e. and the rated current of the different value shown in the panel, adjustable dropout plate has different gaps corresponding to adjusting knob.That is to say rated current corresponding to different value, adjustable dropout plate is corresponding to the gap of adjusting knob, fixedly the dropout plate can be by the mensuration and the adjustment of batch production with the gap of adjustment knob, adjust screw and be and before product export, pack in the through hole of adjustable dropout plate, according to needed rated current, push away inward and adjust screw and drive adjustable dropout plate, adjust between lozenges on the adjustable dropout plate and the adjustment knob and have adjustable clearance along fixedly dropout plate slippage.And when constructing at the scene, as long as press the panel indicated value rotates and adjust knob, need not regulate the adjustment knob and can reach load current value accurately.Therefore have simple to operate, accurately, safe and reliable characteristics.
