The travelling contact (6) that cuts off switch (4) is subjected to the driving of operating mechanism (9), this actuating force from the spring or the electromagnet that have omitted among the figure.Overcurrent relay (10) relies on the output of current detector (11) and works, and makes dropout (trigger) mechanism (24) work of the operating mechanism (8) of vacuum circuit-breaker (1).
Interlocking device (12) is used for control to cut off the mechanism of the action between the operating mechanism (8) of the operating mechanism (9) of switch (4) and vacuum circuit-breaker (1), as shown in Figure 6, its formation is: the 1st linkage that operator link (123), interlocked operation bar (121), trip link (126) and control lever (151) are formed and the 2nd linkage of being made up of drive rod (127), floating lever (158) and drive link (130).Interlocked operation bar (121) relies on the axle (122) on the framework (8a) be arranged on operating mechanism (8) and is installed into free to rotately, and the one end passes through pin (124) and combines with operator link (123).The other end of operator link (123) is connected with the opening operation bar (diagram is omitted) of operating mechanism (9).The other end of interlocked operation bar (121) relies on pin (125) to be connected with trip link (126).The upper end of trip link (126) relies on pin (152) to be connected with the control lever (151) of the disconnection action of carrying out operating mechanism (8).Control lever (151) combines with the axle (44) of the stop door bolt (43) of the operating mechanism (8) shown in Fig. 9 (a), with stop door bolt (43) action.Drive rod (127) relies on axle (122) to be installed into free to rotate, floating lever (158) rotates an end that is mounted freely on drive rod (127) by pin (159), and the other end of drive rod (127) makes drive link (130) be connected with the disconnection action stop door bolt (diagram is omitted) of operating mechanism (9) with pin (131).The rotating shaft (27A) of the control lever (14) of operating mechanism (8) forms one with the control lever (26) of the operating mechanism (8) shown in Fig. 9 (a).Be provided with blocking lever (141) at the one end.Rely on this interlocking device (12) to carry out following control, promptly do when disconnecting action, vacuum circuit-breaker (1) is disconnected when tripper, through fixed time rear drive operating mechanism (9), the travelling contact (6) that cuts off switch (4) is disconnected.
Below explanation action, Fig. 7 and Fig. 8 have provided the synchronous oscillogram of the action of this example.As shown in the figure, the high level of each waveform is represented to close, and low level is represented out.Among Fig. 7, the switch of waveform (A) expression vacuum circuit-breaker (1), the switch of switch (4) is cut off in waveform (B) expression.Action when this tripper cuts out is as follows.
Among Fig. 9 (c), rely on manual operation, the action bars (14) of operating mechanism (8) is rotated towards the direction of arrow (A), rotate toward the clockwise direction by connecting rod (28), (30), action bars (25) and axle (27), by the bar axle (136) that combines with axle (27), axle (131) turns clockwise, and contact (2), (3) are closed.Spring this moment (7) is stretched and energy storage.Then, brake (49) is kissed with the roller (48) on the axle (32) that is arranged on arm (26) end and is connect, after decontroling action bars (14), arm (25) and (26) form one, the state that has anticlockwise revolving force with the effect that is subjected to spring force, and be braked device (49) and supporting, the state of this moment is shown in Fig. 9 (a), and the state of contact is shown in the point (a) of the waveform (A) of Fig. 7.Then, rely on the closed operation of operating mechanism (9) and the power that obtains, for example the spring of energy storage or electromagnet etc. make and cut off switch (4) and close.This state is shown in the point (b) of the waveform (B) of Fig. 7.As a result, vacuum circuit-breaker of series connection (1) and cut-out switch (4) are closed, and electric current flows through conductor (7).
Below introduce the situation that this kind tripper is disconnected, among Fig. 6, the operating mechanism (9) that at first cuts off switch (4) carries out opening operation.This operation handlebar operator link (123) is pushed the top of figure to, and making the action bars (121) by pin (124) and its binding is that the center is rotated counterclockwise with axle (122).Its result guides trip link (126) into below by the effect of pin (125), and action bars (151) is clockwise rotated.The left end of pin (125) bulldozing operation bar this moment (128) rotates counterclockwise action bars (128).Shown in chain-dotted line (128a) towards upper right inclination.As a result, turn clockwise, separate from the stop surface (43a) of roller (38b) with the stop door bolt (43) of the operating mechanism (8) shown in Fig. 9 (a) of combining of axle (44) of action bars (151).Because spring (107) is to use intensity to be far longer than spring (36) and (42), therefore, the power of spring (107) counterclockwise rotates action bars (25) by the power of bar axle (136) antagonistic spring (36).Contact (2) separates with contact (3) as a result, and simultaneously, the pin (33) that links connecting rod (28) and (30) moves towards the direction of leaving axle (27), the power of antagonistic spring (42), and holding arms (38) upwards pushes away.This state is shown in Fig. 9 (b).The contact (2) of the operating mechanism (8) of this moment, the state of (3) are shown in the point (C) of the waveform (A) of Fig. 7.Connecting rod (28), (30) are when the state of Fig. 9 (a) enters the state of Fig. 9 (b), and to below is pushed the pin of brake (49) (51) in the end (30A) of connecting rod (30), and brake (49) is turned clockwise.As a result, because roller (48) breaks away from brake (49), thereby make action bars (26) be subjected to spring action towards rotation counterclockwise.Its state is shown in Fig. 9 (c).Rely on the rotation of action bars (26) and be fixed.The axle (27A) of the action bars (14) of operating mechanism (8) is rotated counterclockwise in Fig. 6.Consequently, because blocking lever (141) is depressed the floating lever (158) towards upper right inclination, be that the center is rotated counterclockwise with axle (122) thereby make drive rod (127).The action of drive rod (127) upwards promotes drive link (130), by cutting off the operating mechanism (9) of switch (4), make contact (6) do to disconnect action, in above action, near the roller (34) of linking part that is arranged on connecting rod (30) moves from right to left while rotating in the recess (38a) of arm (38), after forming the elongation state shown in Fig. 9 (b), being returned to the flexion shown in Fig. 9 (c) again needs the time of defined (for example 0.05～0.1 second), therefore, blocking lever (141) is at contact (2) and (3) after separating, after postponing the time of aforementioned defined, pushing floating lever (158), the contact (6) that the result cuts off switch (4) contact (2) and (3) separately after, the time that postpone defined just disconnects.Promptly as shown in Figure 7, because the effect of this interlocking device (12), lag behind the t1 of aforementioned defined time after the time than the disconnection operating point (c) of vacuum circuit-breaker (1), and in the time shown in the point (d) of waveform (B), the contact (6) that cuts off switch (4) becomes disconnection.
Flow through under the situation of conductor (7) in overcurrent and short circuit current, current detector (11) detects its abnormal current, makes overcurrent relay (10) action.Overcurrent relay is worked at the beginning, and the tripping mechanism (24) shown in Fig. 9 (a) also moves, and the end (46) of its plunger (24a) pushing stop door bolt (43) makes it to clockwise rotate.Roller (38b) leaves stop surface (43a), and arm (38) clockwise rotates.Later action is identical with the situation of aforementioned open-circuit operation, and when contact (2) and (3) disconnected, axle (27A) rotated counterclockwise.In the case as shown in Figure 6, trip link (126) does not descend, and therefore pin (125) leaves floating lever (158), and floating lever (158) is in state shown in Figure 6.Even thereby the axle (27A) rotate counterclockwise, blocking lever (141) does not contact floating lever (158) yet, drive link (130) can not be driven to yet the top.Therefore, operating mechanism (9) is failure to actuate, and cuts off switch (4) and keeps closed condition.This state is shown in the point (e) of Fig. 8 (A).Cut-out switch (4) is opened.Its state is shown in the point (f) of Fig. 8 (B).
In the above-mentioned example,, in large-scale circuit breaker, also can drive by motor or oil sector though the operating mechanism (8) of vacuum circuit-breaker (1) can be used manual operation.Also can adopt manual operation to cut off the mode of switch (4).In addition, vacuum circuit-breaker (1) when this tripper is disconnected and the breaking time that needs only the lag time of the action of cutting off switch (4) greater than vacuum circuit-breaker (1) get final product greater than 1 cycle usually.
