Fig. 1 is the cutaway view of the circuit breaker of the example embodiment illustrated according to described technology.
See Fig. 1, circuit breaker 100 comprises can fixed contact 110, movable contact 120, switchgear unit 130 and trip unit 140.
Can be fixedly mounted in circuit breaker 100 to form fixed contact by fixed contact 110.In one embodiment, can be formed by U-bend song by fixed contact 110.
In this case, U-bend song can occur that abnormal current (namely, overload current, transient current and short circuit current) time contrary ground to can the direction of current flow of fixed contact 110 and movable contact 120, can electric repulsion between fixed contact 110 and movable contact 120 to increase.
Movable contact 120 can with can fixed contact 110 opposed and can by switchgear unit 130 rotated with can connect or be separated by fixed contact 110.In one embodiment, movable contact 120 can be moved by the manual operation of switchgear unit 130 or automatically can be moved by trip unit 140.
Switchgear unit 130 can connect with movable contact 120 and movable contact 120 can be made to rotate so as with can connect or be separated by fixed contact 110.In one embodiment, switchgear unit 130 can be manually actuated to be switched on or switched off main circuit and can carry out automatic operation to be switched on or switched off this main circuit by trip unit 140.
Trip unit 140 can detect abnormal current when there is abnormal current and operable automatically switchgear unit 130 to disconnect main circuit.In one embodiment, trip unit 140 comprise magnet 141, armature 142, interim regulon 143, wink lever 144 and move driver plate 145 wink and spring 146 of moving in wink.
On the other hand, trip unit 140 also can comprise hit piece and bimetallic element.Armature 142 can be operated this trip unit 140 when the flowing beyond or equal about 10 times of rated current of main circuit of abnormal current.Bimetallic element can be operated this trip unit 140 when the flowing beyond or equal about 1.3 doubly to 8 times of rated current of main circuit of abnormal current.
Fig. 2 is the cutaway view that such form is shown, that is, the trip unit 140 of the circuit breaker 100 in Fig. 1 is conditioned by moving driver plate 145 wink, and Fig. 3 is the cutaway view that such form is shown, that is, the trip unit 140 of the circuit breaker 100 in Fig. 1 is conditioned by moving driver plate 145 wink.
See Fig. 2 and Fig. 3, trip unit 140 comprises and moves driver plate 145 wink and spring 146 of moving in wink, move driver plate 145 described wink to comprise magnet 141, the armature 142 of actuating solenoid 141, interim regulon 143, operate the wink the lever 144 and cam 145a that contacts with wink lever 144 of interim regulon 143, and described wink moves, the side of the side of armature 142 and interim regulon 143 couples together by spring 146.In one embodiment, trip unit 140 can also comprise the valve 147 of installation switching device unit 130 and the cross bar 148 of restriction valve 147 motion.
Electromagnetic force is produced when magnet 141 can be electrically connected to main circuit and can occur abnormal current in main circuit.In one embodiment, when the flowing beyond or equal about 10 times of rated current of main circuit of abnormal current, magnet 141 can produce the electromagnetic force being enough to pull armature 142.The electromagnetic force intensity of armature 142 can be pulled can to regulate by moving driver plate 145 wink.
Armature 142 can be rotated be electrically connected with magnet 141 and cross bar 148 can be made to rotate by the electromagnetic force produced in magnet 141.In one embodiment, by electromagnetic force by the armature 142 that rotates can move by wink after abnormal current is eliminated the elasticity of spring 146 be returned to rotation before position.
Interim regulon 143 and its side opposed with armature 142 is connected with the side of armature 142 by spring 146 of moving in wink.In one embodiment, the opposite side of interim regulon 143 contact with wink lever 144 and this interim regulon 143 by wink lever 144 rotation and rotate.
Wink lever 144 can operate this interim regulon 143 and can comprise contact cam 145a arm 144a and for making the wink bar axle that rotates of lever 144.In one embodiment, wink lever 144 can by the contact-making surface contacted by arm 144a moving driver plate 145 wink and determine cam 145a, to regulate the anglec of rotation of interim regulon 143.Lever 144 can be rotated in a clockwise direction by moving in wink driver plate 145 and interim regulon 143 can be made to rotate in the counterclockwise direction wink.
Move driver plate 145 wink and comprise the cam 145a that contacts of arm 144a with wink lever 144, this cam 145a forms the multiple partial points 145b corresponding to instantaneous time.
Fig. 4 amplifies the view moving driver plate wink illustrated in Fig. 2 and Fig. 3.
In figs. 2,3 and 4, move driver plate 145 wink and comprise cam 145a, this cam forms the multiple partial points 145b corresponding to instantaneous time when the radius of cam circumferentially increases gradually.In one embodiment, cam 145a can contact wink lever 144 to regulate wink the lever 144 and rotation of interim regulon 143.
Move in wink spring 146 by move driver plate 145 by wink and rotate wink lever 144 and interim regulon 143 stretch or shrink.
The vertical extension of moving in wink between spring 146 and armature 142 is defined as torque arm length, this torque arm length by wink lever 144 and the multiple partial points 145b moving driver plate 145 wink between contact regulate.In one embodiment, driver plate 145 can carry out determination operation trip unit 140 in main circuit goes out by adjustment force arm lengths levels of current during existing abnormal current is moved wink.
When wink lever 144 the partial points of arm 144a from the partial points of minor radius to large radius in the cam 145a moving driver plate 145 wink contact gradually time, wink lever 144 increase gradually and turn clockwise.Therefore, interim being rotated counterclockwise of regulon 143 increases gradually and causes torque arm length to increase.The levels of current of operation trip unit 140 improves according to the increase of torque arm length.
When electric current to exceed when there is abnormal current by moving instantaneous current value that driver plate 145 determines wink, trip unit 140 makes armature 142 rotate by the electromagnetic force produced in magnet 141.
Armature 142 rotates in the counterclockwise direction by the electromagnetic force produced in magnet 141 and cross bar 148 is rotated.Cross bar 148 is rotated to remove to the restriction of valve 147 and valve 147 is rotated.Valve 147 operates this switchgear unit 130 by the rotation of this valve 147.
Although describe the present invention with reference to its multiple illustrative embodiments, should be appreciated that, it may occur to persons skilled in the art that fall into principle of the present disclosure spirit and scope in many other amendment and execution modes.
