Embodiment
By particular specific embodiment, execution mode of the present utility model is described below, person skilled in the art scholar the content disclosed by this specification can understand other advantages of the present utility model and effect easily.
Notice, structure, ratio, size etc. that this specification institute accompanying drawings illustrates, content all only in order to coordinate specification to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this specification as " on ", D score, "left", "right", " centre " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
The utility model provides one wink streaming current adjustable breaker, as shown in Figures 1 and 2, comprise electromagnetic release mechanism, described electromagnetic release mechanism comprises electromagnet 4, and mutually against snap close 5 and tripping (not shown), described electromagnetic release mechanism also comprises moving frame 1, spring 2 and adjusting screw(rod) 3, described moving frame 1, snap close 5 and tripping are the link gears of a set of routine, the middle part of described moving frame 1 is hinged in a rotating shaft 11, one end and the described snap close 5 of moving frame 1 lean, the other end of moving frame 1 is connected with the first end 22 of described spring 2, spring 2 pairs of moving frames 1 apply elastic resistance, moving frame 2 is stoped to be rotated, second end 21 of described spring 2 is connected with adjusting screw(rod) 3, rotate the position of the second end 21 in adjusting screw(rod) 3 i.e. adjustable springs 2, thus cause the change of elastic force, the first end 22 of spring 2 produces corresponding deformation simultaneously, the resistance that spring 2 is applied to moving frame 1 produces corresponding change.Described electromagnet 4 comprises a push rod 41, described push rod 41 contacts with one end of moving frame 1, when passing through short circuit current in circuit, static iron core in electromagnet 4 and the magnetic force produced between dynamic iron core, act in moving frame 1 by push rod 41, produce anticlockwise torque, this torque is greater than opposing torque that the spring 2 pairs of moving frames 1 apply thus promotes moving frame 1 rotates, and moving frame 1 and snap close 5 are triped.
As Fig. 4 and Fig. 5, preferably, described snap close 5 is hinged in a rotating shaft 51, and described snap close 5 is provided with the first butting section 52, and is leant with described tripping by the first butting section 52, preferably, described snap close is also provided with the second butting section 53, and is leant, when moving frame 1 can not rotate counterclockwise with described moving frame 1 by the second butting section 53, snap close 5 can not rotate, and is in lockup state.
As shown in Figures 2 and 6, preferably, described circuit breaker also comprises a housing 6, and housing is provided with an adjustment hole 61, and one end of described adjusting screw(rod) 3 is arranged in adjustment hole 61 rotationally, can operate adjusting screw(rod) 3 by adjustment hole 61.Such as spring 2 can be a stage clip, changes the upper-lower position of adjusting screw(rod) 3, can the pressure of regulating spring 2.Preferably, the cylinder of described adjusting screw(rod) 3 is provided with helicla flute 31, second end 21 of described spring 2 bends to helical form, and be bonded in the helicla flute 31 of described adjusting screw(rod) 5, further, the degree of depth in described helicla flute 31 and the diameter of spring 2 close, make the second end 21 of thread groove 31 and spring 2 coordinate more reliable, preferably, described spring 2 is torsion spring.For torsion spring, when rotating adjusting screw(rod) 3, the upper-lower position of adjusting screw(rod) 3 in housing 6 does not change, by means of only the threaded engagement between the second end 21 of torsion spring and helicla flute 31, the position of the second end 21 of torsion spring is changed, thus change the size of torsion spring torsion, correspondingly, the first end 22 of torsion spring changes relative to the resistance of moving frame 1.
As shown in Figure 1, preferably, L-shaped or the similar shape of described moving frame 1, the vertical straight flange of L-type is hinged in rotating shaft 11, and the vertical end of straight flange is connected with the first end 22 of described spring, and the limit anyhow of L-type contacts with moving frame 1, when electromagnet action, anyhow the limit of described push rod 41 upwardly moving frame 1, drives moving frame 1 11 to rotate counterclockwise around the shaft, and moving frame 1 and snap close 5 are thrown off.
Operation principle of the present utility model is as follows:
When the current circuit of circuit breaker is short-circuited fault, electric current sharply increases, enough large magnetic force is produced between dynamic iron core in electromagnet 4 and static iron core, promote push rod 41 to move upward, push rod 41 drives moving frame 1 overcome the resistance of first end 22 applying of spring 2 and rotate counterclockwise, now snap close 5 rotates and throws off with described moving frame 1, and snap close 5 and tripping is simultaneously thrown off, thus circuit breaker is disconnected.When the loop current of circuit breaker is at normal value or when being less than the current protection value of setting; the active force of push rod 41 pairs of moving frames 1 can not overcome the resistance of spring 2 pairs of moving frames 1; moving frame 1 can not be rotated; now moving frame 1 and snap close 5 are held against state; snap close 5 and tripping are not thrown off; therefore, circuit breaker can not trip.
The utility model can regulate wink streaming current set point by rotating adjusting screw(rod) 3, as shown in Figure 3, when needs increase wink streaming current set point, rotatable adjusting screw(rod) 3, increase the resistance of spring 2 pairs of moving frames 1, in like manner, reverse rotation adjusting screw(rod) 3 can reduce the wink streaming current set point of circuit breaker.
In sum, the utility model effectively overcomes various shortcoming of the prior art and tool high industrial utilization.
