Abstract
The invention relates to a delayed tripping device of a disconnector. The problems that sensitivity is bad, reliability is low and great potential safety hazards exist when the existing disconnector is tripped delayed are mainly solved. A pushing rod device comprises a pulling rod in a V-shaped structure and a hinged shaft fixed on a shellbody. A V-shaped turning position of the pulling rod is connected with the hinged shaft in a hinged mode. One end of the pulling rod is fit with two sheet metals and the other end of the pulling rod is fit with a lock catch. The pulling rod can revolve along the center of the hinged shaft. The delayed tripping device of the disconnector has the advantages of being high in sensitivity, good in stability and high in safety.
Description
Technical field
The present invention relates to a kind of miniature circuit breaker, refer in particular to a kind of circuit breaker delayed releasing device.
Background technology
Switch switchgear for power department is the assurance Electrical Safety, carries out the requisite equipment of circuit switching.Has the pull bar that the circuit breaker of delayed releasing generally comprises the temperature-sensitive element bimetal leaf, cooperates with this bimetal leaf, and the snap close that cooperates with the institute pull bar and with the tripping of snap close phase clamping, common pull bar is " one " font pull bar, be affiliated on release lever and bimetal leaf, undertaken spacingly by housing, do the time spent and easily wave, and be subjected between each components and parts frictional influence larger, sensitivity and the reliability of motion are very low, have great potential safety hazard.
Summary of the invention
In order to overcome deficiency and the defective in the background technology, the invention provides a kind of circuit breaker delayed releasing device, have when mainly solving existing circuit breaker delayed releasing that sensitivity is poor, reliability is low, there is the problem of very big potential safety hazard.
Technical scheme of the present invention is: a kind of circuit breaker delayed releasing device, comprise bimetal leaf, push rod device and snap close, it is characterized in that: described push rod device includes the pull bar and the jointed shaft that is fixed on the housing of V-shaped structure, V-arrangement turning point and the jointed shaft of described pull bar are hinged, one end of described pull bar matches with bimetal leaf, the other end matches with described snap close, and described pull bar can be along the jointed shaft central rotation.
Be arranged with case on the described jointed shaft, the upper surface of case is provided with v-depression, and described drag link sleeve is contained in the described v-depression.
Be provided with the card base that cooperates with described pull bar location in the described v-depression.
Described snap close is provided with arc groove, and an end of described pull bar is provided with the first drag hook, and described the first drag hook is slidingly matched in described arc groove.
The other end of described pull bar is provided with the second drag hook, the end face phase clamping matching of described the second drag hook and the opposite side of the corresponding jointed shaft of described bimetal leaf.
Beneficial effect of the present invention: owing to taking such scheme, circuit breaker delayed releasing device of the present invention, the pull bar of the v-shaped structure that arranges be fixed on jointed shaft on the housing and be hinged and be rotatably assorted, avoided the friction of the generation of the components and parts such as pull bar and housing and release lever, and leg-of-mutton 3 rotating manners of employing V-arrangement, have highly sensitive, good stability, safe characteristics.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of pull bar among Fig. 1.
Fig. 3 is the structural representation of case among Fig. 1.
Fig. 4 is assembling schematic diagram of the present invention.
Among the figure, bimetal leaf 1, pull bar 2, the first drag hooks 21, the second drag hooks 22, snap close 3, arc groove 31, jointed shaft 4, case 5, v-depression 51, card base 52.
Embodiment
The below is described further embodiments of the invention for accompanying drawing:
Shown in figure,
This circuit breaker delayed releasing device, comprise bimetal leaf 1, push rod device and snap close 3, described push rod device includes the pull bar 2 and the jointed shaft 4 that is fixed on the housing of V-shaped structure, V-arrangement turning point and the jointed shaft 4 of described pull bar 2 are hinged, one end of described pull bar 2 matches with bimetal leaf 1, the other end matches with described snap close 3, and described pull bar 2 can be along jointed shaft 4 central rotations.In the circuit breaker running; in when, in the circuit overload current occuring when; two golden hairs in the contact system are given birth to crooked; drive the pull bar one end interlock that matches in the push rod device; through the rotary arm of jointed shaft, make the pull bar other end drive the snap close interlock, snap close and tripping are threaded off; thereby circuit breaker is disconnected, play the time-delay overload protection.Because the connecting rod of V-arrangement and the integration of operation of jointed shaft, so that avoided the friction of the generation of pull bar and the components and parts such as housing and release lever, and leg-of-mutton 3 rotating manners of employing V-arrangement, the problem that has effectively replaced tradition " one " type connecting rod poor stability, have highly sensitive, good stability, safe characteristics.
Be arranged with case 5 on the described jointed shaft 4, the upper surface of case 5 is provided with v-depression 51, and described pull bar 2 is sleeved in the described v-depression 51.Pull bar V-arrangement break and jointed shaft are hinged, and upper surface effectively limits the axial slip of pull bar by the nested setting of case to pull bar, has guaranteed the stability of whole mechanism, has greatly improved the security performance of circuit breaker.
Be provided with the card base 52 that cooperates with described pull bar 2 location in the described v-depression 51.As preferentially, be provided with a plurality of card bases and be evenly distributed in the v-depression, and with the upper surface clamping matching of pull bar, prevent that pull bar breaks away from case, more reliable and more stable.
Described snap close 3 is provided with arc groove 31, and an end of described pull bar 2 is provided with the first drag hook 21, and described the first drag hook 21 is slidingly matched in described arc groove 31.The other end of described pull bar 2 is provided with the second drag hook 22, the end face phase clamping matching of described the second drag hook 22 and the opposite side of the corresponding jointed shaft 4 of described bimetal leaf 1.When circuit breaker disconnected, described the first drag hook can slide in arc groove freely, had avoided the unlatching of circuit breaker to disturb, behind breaker closing, the inwall phase clamping of the first drag hook and arc groove after bimetal leaf is subjected to overload current operation bending, is given a power with a vertical pull bar direction of the second drag hook, so that pull bar rotates around jointed shaft, drive snap fit, simultaneously snap close and tripping threaded off, and circuit breaker is disconnected, have highly sensitive, the characteristics of good stability.
Embodiment should not be considered as the restriction to invention, but any improvement of doing based on spirit of the present invention, all should be within protection scope of the present invention.
