Description
Technical Field
[0001] The present invention relates to the technical field of circuit breakers, and in particular to an energy storage indication structure of a circuit breaker, an operating mechanism of a circuit breaker and a circuit breaker. Background Art
[0002] Most of the energy storage indicators of frame circuit breakers in the industry can only provide energy storage and energy release status indications. When the operating mechanism completes the energy storage of the closing spring assembly through the energy storage cam, the energy storage indicator, under the action of the indicator's reset spring force, causes its contact finger (contact part) to enter the outer edge groove of the energy storage cam, and the energy storage indicator in the operating mechanism indicates the energy storage state. When the mechanism is closed, the closing spring is released and then pushes the energy storage lever and the energy storage cam to move. At this time, the energy storage cam rotates counterclockwise around the center axis, thereby pushing the energy storage indicator to rotate clockwise around the axis, causing the contact finger to slide out of the outer edge groove of the energy storage cam, and maintain contact with the outer edge (outer circumferential surface) of the energy storage cam under the action of the reset spring force. The energy storage indicator status switches to indicate the energy release state, but the existing frame circuit breaker cannot fully reflect whether the circuit breaker can be closed. Summary of the invention
[0003] In view of the deficiencies in the prior art, the present invention provides an energy storage indication structure for a circuit breaker, which mainly solves the technical problem that the energy storage indicator of the existing frame circuit breaker can only indicate whether the closing spring assembly of the circuit breaker is in an energy storage state, but cannot fully reflect whether the circuit breaker can perform a closing operation.
[0004] To achieve the above object, the present invention is achieved through the following technical solutions: A circuit breaker energy storage indication structure comprises a state indicator movably mounted in an operating mechanism, wherein the state indicator is provided with a first indication portion and a second indication portion respectively corresponding to the energy storage and energy release states of a closing spring assembly of the circuit breaker, and a resisting portion is provided on the state indicator, and the resisting portion slides into a groove on an outer circumferential surface of an energy storage cam of the circuit breaker or abuts against the outer circumferential surface of the energy storage cam to rotate the state indicator accordingly, thereby switching the corresponding states of the first indication portion and the second indication portion and the circuit breaker indication window, and a limiting portion is provided on the state indicator, and a third indication portion is provided between the first indication portion and the second indication portion, and when the closing spring assembly completes energy storage and the closing limit end of the cantilever on the main shaft of the circuit breaker abuts against the opening and closing limit shaft of the circuit breaker to form a closing state, the resisting portion corresponds to the groove, and the rotation angle of the state indicator is limited by the resisting and limiting cooperation between the limiting portion and the closing limit end, and the third indication portion is switched to a display state corresponding to the circuit breaker indication window, so as to indicate that the closing spring assembly is in an energy storage state but the circuit breaker cannot be closed.
[0005] Furthermore, the limiting portion has an arc-shaped mating surface adapted to the arc-shaped end of the closing limit end of the cantilever, and the arc-shaped mating surface abuts against the arc-shaped end of the closing limit end to form a limiting fit, so as to limit the rotation angle of the status indicator without interfering with the movement of the cantilever to the opening state position, and enable the abutting portion of the status indicator to only partially slide into the corresponding groove, and the third indicating portion switches to the display state corresponding to the circuit breaker indication window.
[0006] Furthermore, a reset spring connecting portion is provided on the status indicator, and a reset spring is connected between the status indicator and the operating mechanism via the reset spring connecting portion. The reset elastic force of the reset spring makes the status indicator have a movement tendency of automatic rotation and reset, so that the abutment portion is tightly abutted against the outer circumferential surface of the energy storage cam, and the first indicating portion is maintained in a display state corresponding to the circuit breaker indication window, and when the energy storage cam rotates to the position of the groove corresponding to the abutment portion, the abutment portion can automatically slide into the groove, so that the status indicator automatically resets and rotates, and when the abutment portion slides into place in the groove, the second indicating portion switches to a display state corresponding to the circuit breaker indication window.
[0007] Furthermore, the words “Charged OK” are marked on the first indicator portion to indicate that the closing spring assembly of the circuit breaker is in an energy storage state and the circuit breaker can be closed, the words “Discharged” are marked on the second indicator portion to indicate that the closing spring assembly of the circuit breaker is in an energy release state, and the words “Charged OK” are marked on the third indicator portion to indicate that the closing spring assembly of the circuit breaker is in an energy storage state but the circuit breaker cannot be closed.
[0008] Furthermore, a rotating connection portion is provided on the status indicator, and the rotating connection portion is rotatably connected to the operating mechanism through a rotating shaft structure.
[0009] Based on the same inventive concept, the present invention also provides an operating mechanism of a circuit breaker, including a mechanism body, on which are provided an opening half-shaft, a circuit breaker main shaft, a cantilever connected to the circuit breaker main shaft, an opening and closing limit shaft used in conjunction with the cantilever, a closing spring assembly, an energy storage cam and an energy storage lever connected to the closing spring assembly, and an interlocking member and an operating mechanism of the circuit breaker as described above, wherein the opening half-shaft is configured to be restricted from rotating when the fault trip indication of the circuit breaker is not reset, the interlocking member is arranged correspondingly to the opening half-shaft, and a stop limit structure is arranged between the interlocking member and the opening half-shaft for restricting the interlocking member from automatically resetting and moving back when the fault trip indication of the circuit breaker is not reset, and the interlocking member is connected to the status indicator via a linkage structure.
[0010] Further, when the fault trip indication of the circuit breaker is not reset so that the interlocking member is restricted by the opening half-shaft to keep the status indicator stationary, the third indication portion of the status indicator is configured to be in a status position corresponding to the circuit breaker indication window to indicate that the closing spring assembly is in an energy storage state but the circuit breaker cannot be closed.
[0011] Furthermore, a stop fitting portion is provided on the interlocking member, and a limit contact finger is provided on the opening half-shaft. When the status indicator rotates to a position where its third indicating portion corresponds to the circuit breaker indicating window and the opening half-shaft rotates, the limit contact finger on the opening half-shaft cooperates with the stop fitting portion on the status indicator to form a stop limit structure to limit the automatic resetting of the interlocking member.
[0012] Furthermore, a linkage contact finger is provided on the status indicator, a linkage groove is provided on the interlocking member, a linkage shaft rod is provided on the linkage contact finger, and the linkage shaft rod is movably embedded in the linkage groove to form a linkage structure.
[0013] Based on the same inventive concept, the present invention further provides a circuit breaker, comprising any of the above-mentioned energy storage indication structures of the circuit breaker or the operating mechanism of the circuit breaker.
[0014] The above technical solution has the following advantages or beneficial effects:
[0015] In the energy storage indication structure of the circuit breaker, the operating mechanism of the circuit breaker and the circuit breaker described in the present invention, a limit part is added to the status indicator, and the limit part is configured to be able to correspondingly abut against the closing limit end when the closing limit end of the cantilever on the main shaft of the circuit breaker abuts against the opening and closing limit shaft of the circuit breaker to form a closed state, and the abutment limit of the limit part and the closing limit end cooperates so that the status indicator can only rotate at a predetermined angle, and a third indicator part located between the first indicator part and the second indicator part is provided between the switching action angle travel of the first indicator part and the second indicator part, and the third indicator part is configured to rotate and switch to a display state corresponding to the circuit breaker indication window when the abutment limit of the limit part and the closing limit end cooperates, and the third indicator part indicates that the closing spring assembly of the circuit breaker is in the energy storage state, but the circuit breaker is in the closed state, and the circuit breaker cannot be closed at this time. In this way, the status indicator can not only indicate the energy storage and energy release status of the closing spring assembly, but also indicate whether the circuit breaker can be closed, which is beneficial to improving the operational safety of the circuit breaker.

[0025] Please refer to the attached Figure 1 To Attachment Figure 5An embodiment of the present invention provides an energy storage indication structure of a circuit breaker, comprising a state indicator 1 movably mounted in an operating mechanism, the state indicator 1 being provided with a first indication portion 11 and a second indication portion 12 corresponding to the energy storage and energy release states of a closing spring assembly 3 of the circuit breaker, respectively, and a resisting portion 13 being provided on the state indicator 1, the resisting portion 13 sliding into a groove 21 on the outer circumferential surface of an energy storage cam 2 of the circuit breaker or abutting against the outer circumferential surface of the energy storage cam 2 to cause the state indicator 1 to rotate accordingly, thereby switching the corresponding states of the first indication portion 11 and the second indication portion 12 and the circuit breaker indication window, wherein the state indicator 1 is characterized in that A limiting portion 14 is provided on the status indicator 1, and a third indicating portion 15 is provided between the first indicating portion 11 and the second indicating portion 12. When the closing spring assembly 3 completes energy storage and the closing limiting end 51 of the cantilever 5 on the circuit breaker main shaft 4 abuts against the opening and closing limiting shaft 6 of the circuit breaker to form a closed state, the abutting portion 13 corresponds to the groove 21, and the abutting and limiting cooperation between the limiting portion 14 and the closing limiting end 51 is used to limit the rotation angle of the status indicator 1, and the third indicating portion 15 is switched to a display state corresponding to the circuit breaker indication window to indicate that the closing spring assembly 3 is in an energy storage state but the circuit breaker cannot be closed. It can be understood that, in this embodiment, the status indicator 1 is additionally provided with a limit portion 14 on the basis of the existing structure, and the limit portion 14 is configured to be able to correspondingly contact the closing limit end 51 when the closing limit end 51 of the cantilever 5 on the main shaft 4 of the circuit breaker contacts the opening and closing limit shaft 6 of the circuit breaker to form a closed state, and the contact limit of the limit portion 14 and the closing limit end 51 cooperate so that the status indicator 1 can only rotate a predetermined angle, and a third indicator portion 15 located between the first indicator portion 11 and the second indicator portion 12 is provided between the switching action angle travel of the first indicator portion 11 and the second indicator portion 12, and the third indicator portion 15 is configured to rotate and switch to a display state corresponding to the circuit breaker indication window when the contact limit of the limit portion 14 and the closing limit end 51 cooperates, and the third indicator portion 15 indicates that the closing spring assembly 3 of the circuit breaker is in the energy storage state, but the circuit breaker is in the closed state, and the circuit breaker cannot be closed at this time.

In this embodiment, since the limiting portion 14 has an arc-shaped matching surface 141 that matches the arc-shaped end of the closing limiting end 51 of the cantilever, even if the limiting portion 14 forms an abutting limiting match with the closing limiting end 51, it only limits the rotation angle of the status indicator 1, and does not affect the normal operation of the cantilever 5, so that the circuit breaker can perform the opening operation normally.
[0027] Please refer to the attached Figure 1 To Attachment Figure 5 In one preferred embodiment, a reset spring connection portion 16 is further provided on the status indicator 1, and a reset spring is connected between the status indicator 1 and the operating mechanism through the reset spring connection portion 16.
