Description
Technical Field
Embodiments of the present disclosure relate generally to circuit breakers and, more particularly, to a motor operator for a circuit breaker and a method of manufacturing a motor operator.
Background
The use of motor operators to allow motor-assisted operation of circuit breakers is well known. The motor operator is typically secured to the housing of the circuit breaker. A control lever within the motor operator mechanically interacts with an operating handle of the circuit breaker that extends from a housing of the circuit breaker. The control rod is operatively connected to the motor within the motor operator. The motor drives the control lever, which in turn moves the operating handle to operate the circuit breaker. The operating handle moves between "on", "off" and "reset" positions depending on the direction of rotation of the motor. In this way, the circuit breaker can be switched between different states, for example an on state (also referred to as closed state) and an off state (also referred to as open state).
The motor operator typically includes three modes of operation, namely an automatic mode, a manual mode and a locking mode. In the automatic mode, the motor operator may be remotely operated to adjust the operating state of the circuit breaker. In the manual mode, the motor operator may be manually operated, and thus the operating state of the circuit breaker may be adjusted by a user on site. In the locked mode, the motor operator is locked, and thus the operating state of the circuit breaker cannot be adjusted by the motor operator.
The mode of operation of the motor operator may be adjusted by means of a mode selector. For example, the user may move the mode selector to positions corresponding to the automatic mode, the manual mode, and the locked mode, respectively. In the conventional motor operator, even when the circuit breaker is in the on state, the mode selector can be moved from the positions corresponding to the automatic mode and the manual mode to the position corresponding to the lock mode. This is unsafe for the user during use of the motor operator. In addition, the user may still remove the motor operator from the circuit breaker while the motor operator is in the locked mode. This is therefore not a true locking function, which is not safe for the user.

Embodiments of the present disclosure provide a motor operator for a circuit breaker and a method of manufacturing the motor operator.
In a first aspect, a motor operator for a circuit breaker is provided. The motor operator includes: a base plate adapted to be secured to a circuit breaker; a mounting plate disposed substantially vertically on the substrate; a mode selector disposed on a side of the mounting plate away from the base plate and configured to be switchable in a first direction along the side of the mounting plate between an automatic position corresponding to an automatic operation mode of the motor operator, a manual position corresponding to a manual operation mode of the motor operator, and a lock position corresponding to a lock mode of the motor operator, the mode selector including a first hole extending in the first direction; and a push lever configured to be switchable between a first position corresponding to an on state of the circuit breaker and a second position corresponding to an off state of the circuit breaker in a second direction intersecting the first direction, the push lever including a blocking portion configured to be located in the first hole when the push lever is in the first position to block the mode selector from reaching the lock position, and to be located outside the first hole when the push lever is in the second position to allow the mode selector to reach the lock position.
In some embodiments, the push lever further comprises a first body portion slidably coupled to the mounting plate and including a first end proximate the mode selector and a second end proximate the base plate, and the blocking portion is disposed at the first end of the first body portion and protrudes toward the base plate.
In some embodiments, the base plate includes a second aperture, and the push lever further includes: a first actuation portion disposed at the second end of the first body portion and extending through the second aperture, the first actuation portion configured to be driven by a status indicating member of the circuit breaker such that the push lever is switchable between the first position and the second position.
In some embodiments, the motor operator further comprises an indicator configured to present an on state of the circuit breaker when the push lever is in the first position and to present an off state of the circuit breaker when the push lever is in the second position.
In some embodiments, the push lever further comprises a third aperture, and the indicator comprises: an indicating portion configured to present a state of the circuit breaker; and a first shaft disposed in the third bore and configured to be driven by the push lever when the push lever moves in the second direction such that the indication part rotates to assume an on state or an off state of the circuit breaker.
In some embodiments, the mounting plate is removably coupled to the base plate.
In some embodiments, the motor operator further comprises: a locking lever rotatably coupled to the mounting plate and configured to be actuated by the mode selector to lock the mounting plate to the base plate when the mode selector is in the locked position and to release the mounting plate from the base plate when the mode selector is in the automatic position or the manual position.
In some embodiments, the locking lever comprises: a second body portion rotatably coupled to the mounting plate via a mounting pin; a second actuating portion disposed at an end of the second body portion proximate to the mode selector and configured to be driven by the mode selector when the mode selector is switched from the automatic position or the manual position to the locked position such that the second body portion can be rotated; and a locking portion disposed at the other end of the second body portion and configured to be locked to the base plate when the mode selector is in the locking position and unlocked from the base plate when the mode selector is in the automatic position or the manual position.
In some embodiments, the mode selector further comprises: a driving portion protruding toward the base plate and configured to drive the second actuating portion when the mode selector is switched from the automatic position or the manual position to the lock position.
In some embodiments, the substrate comprises: a restricting member configured to catch the locking portion when the mode selector is in the locking position.
In some embodiments, the motor operator further comprises: a spring configured to reset the locking lever when the locking lever is not actuated by the mode selector.
In some embodiments, the motor operator further comprises: a tag configured to indicate a position of the mode selector.
In a second aspect, a method of manufacturing a motor operator for a circuit breaker is provided. The method comprises the following steps: providing a substrate adapted to be secured to a circuit breaker; providing a mounting plate arranged substantially vertically on a substrate; providing a mode selector disposed on a side of the mounting plate remote from the base plate and configured to be switchable in a first direction along the side of the mounting plate between an automatic position corresponding to an automatic operation mode of the motor operator, a manual position corresponding to a manual operation mode of the motor operator, and a lock position corresponding to a lock mode of the motor operator, the mode selector including a first hole extending in the first direction; and providing a push lever configured to be switchable in a second direction intersecting the first direction between a first position corresponding to an on state of the circuit breaker and a second position corresponding to an off state of the circuit breaker, the push lever including a blocking portion configured to be located in the first hole when the push lever is in the first position to block the mode selector from reaching the locked position and to be located outside the first hole when the push lever is in the second position to allow the mode selector to reach the locked position.
According to various embodiments of the present disclosure, adjustment of the operating mode of the motor operator is limited by the state of the circuit breaker, which is reflected by the position at which the lever is pushed. Specifically, when the push lever is in the first position, the blocking portion of the push lever is positioned in the first aperture of the mode selector to prevent the mode selector from reaching the locked position. Further, when the push lever is in the second position, the blocking portion of the push lever is positioned outside the first aperture to allow the mode selector to reach the locked position. In this way, the motor operator can be prevented from entering the locked mode when the circuit breaker is in the on state. In other words, the motor operator can be switched to the locked mode only when the circuit breaker is in the off state. In this way, the safety performance of the motor operator is improved during use of the motor operator.

Detailed Description
The principles of the present disclosure will now be described with reference to a few exemplary embodiments thereof as illustrated in the accompanying drawings. While the exemplary embodiments of the present disclosure have been illustrated in the accompanying drawings, it is to be understood that the embodiments are described merely to assist those skilled in the art in better understanding and thereby enabling the disclosure, and do not limit the scope of the disclosure in any way.
The term "comprising" or "including" and variants thereof are to be understood as open-ended terms, which mean "including but not limited to". The term "or" should be understood as "and/or" unless the context clearly dictates otherwise. The term "based on" is to be understood as "based at least in part on". The term "operable to" means that a function, action, or state can be achieved by an operation caused by a user or an external mechanism. The terms "one embodiment" and "an embodiment" should be understood as "at least one embodiment". The term "another embodiment" should be understood as "at least one other embodiment". The terms "first," "second," and the like may refer to different or the same object. Other definitions, whether explicit or implicit, may be included below. The definitions of the terms are consistent throughout the specification unless the context clearly dictates otherwise.
Unless specified or limited otherwise, the terms "mounted," "connected," "supported," and "coupled" and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings. Further, "connected" and "coupled" are not restricted to physical or mechanical connections or couplings. In the description below, like reference numerals and signs are used to describe the same, similar or corresponding parts in the figures. Other definitions, whether explicit or implicit, may be included below.
As described above, even when the circuit breaker is in the on state, the conventional motor operator can be switched to the lock mode; additionally, when the motor operator is in the locked mode, the conventional motor operator can still be removed from the circuit breaker; therefore, it is not safe for a user to operate the conventional motor operator. According to an embodiment of the present disclosure, in order to improve safety performance of the motor operator, adjustment of an operation mode of the motor operator is limited by a state of the circuit breaker, and the motor operator is prevented from being detached from the circuit breaker when the motor operator is in a locking mode. As will be described in detail in the following paragraphs, the above concepts may be implemented in various ways. Hereinafter, the principle of the present disclosure will be described in detail with reference to fig. 1 to 15. In the drawings, some conventional components of a motor operator (such as a motor and a lever for moving an operating handle of a circuit breaker) are not shown to avoid adversely obscuring the concepts of the present disclosure.
Fig. 1 shows a schematic diagram of a motor operator 100 for a circuit breaker according to an embodiment of the present disclosure, and fig. 2 shows an exploded view of the motor operator 100 as shown in fig. 1. As shown, the motor operator 100 for a circuit breaker generally includes a base plate 1, a mounting plate 2, a mode selector 3, and a push lever 4.
The base plate 1 may be a part of the housing of the motor operator 100 or may be a separate component. In use, the base plate 1 is fixed to a circuit breaker to mount the motor operator 100 to the circuit breaker. For example, the base plate 1 may be fixed to the circuit breaker by screws or other fasteners. The scope of the present disclosure is not limited in this respect.
The mounting plate 2 is arranged substantially vertically on the base plate 1 to support some of the internal components of the motor operator 100. The mounting plate 2 may be integrally formed on the substrate 1 or detachably mounted on the substrate 1. As an example, as shown in fig. 1 to 3, the mounting plate 2 is detachably coupled to the base plate 1 via a hinge structure 9. The hinge structure 9 comprises two mating parts, namely a receiving part 13 on the base plate 1 and a rotation axis 22 on the mounting plate 2. The rotation shaft 22 is rotatably connected to the receiving portion 13. With this arrangement, the mounting board 2 is detachably coupled to the base board 1. In other embodiments, the mounting plate 2 may be removably coupled to the base plate 1 by other attachment features.
Fig. 4 shows a schematic view of the mode selector 3 of the motor operator 100 as shown in fig. 1. Referring to fig. 1, 2 and 4, a mode selector 3 is arranged on a side of the mounting plate 2 remote from the base plate 1. The mode selector 3 is switchable in the first direction X along one side of the mounting plate 2 between an automatic position AUTO corresponding to an automatic operation mode of the motor operator 100, a manual position MAN corresponding to a manual operation mode of the motor operator 100, and a LOCK position LOCK corresponding to a LOCK mode of the motor operator 100. In the embodiment of the present disclosure, the mode selector 3 may be directly connected to the mounting plate 2, or indirectly mounted on the mounting plate 2 via other members.
In one embodiment, as shown in fig. 1, 2 and 4, the mode selector 3 includes a selection handle 33. By pushing the selection handle 33, the mode selector 3 can be switched to a different operating mode. In the automatic mode, the motor operator 100 may be remotely operated to adjust the operating state of the circuit breaker. In the manual mode, the motor operator 100 may be manually operated, and thus the operating state of the circuit breaker may be adjusted by a user on site. In the lock mode, the motor operator 100 is locked, and thus the operating state of the circuit breaker cannot be adjusted by the motor operator 100.
Fig. 5 shows a schematic view of the push lever 4 of the motor operator 100 shown in fig. 1. Referring to fig. 1, 2 and 5, the push lever 4 can be switched in a second direction Z intersecting the first direction X between a first position corresponding to an on state of the circuit breaker and a second position corresponding to an off state of the circuit breaker. In some embodiments, as shown in fig. 1, the first direction X is substantially orthogonal to the second direction Z. In other embodiments, the first direction X may obliquely intersect the second direction Z. The scope of the present disclosure is not limited in this respect.
The push lever 4 may be located at a first position when the circuit breaker is in an on state, and the push lever 4 may be located at a second position when the circuit breaker is in an off state. The movement of the push lever 4 may be triggered by a status indicating member (not shown) of the circuit breaker. When the circuit breaker is switched between the on state and the off state, the state indicating member of the circuit breaker may drive the push lever 4 to move between the first position and the second position.
As shown in fig. 1 and 4, a first hole 31 extending in the first direction X is provided in the mode selector 3. As shown in fig. 1 and 5, the push lever 4 comprises a blocking portion 41 intended to cooperate with the mode selector 3. When the push lever 4 is in the first position, the blocking portion 41 is located in the first hole 31 of the mode selector 3 to prevent the mode selector 3 from reaching the LOCK position LOCK. When the push lever 4 is in the second position, the blocking portion 41 may be located outside the first hole 31 to allow the mode selector 3 to reach the LOCK position LOCK. With this arrangement, the motor operator 100 can be prevented from entering the lock mode when the circuit breaker is in the on state.
In some embodiments, as shown in fig. 1, 2 and 6, the motor operator 100 further includes an indicator 5. The indicator 5 is operable to assume an on state of the circuit breaker when the push lever 4 is in the first position and an off state of the circuit breaker when the push lever 4 is in the second position. In other words, the indicator 5 may display a symbol "ON" when the circuit breaker is in the ON state, and the indicator 5 may display a symbol "OFF" when the circuit breaker is in the OFF state.
In some embodiments, as shown in fig. 1 and 5, the push lever 4 further includes a first body portion 42 slidably coupled to the mounting plate 2 along the second direction Z. The first body portion 42 may be directly connected to the mounting plate 2 or indirectly mounted on the mounting plate 2 via other connecting means. The first body portion 42 includes a first end 421 near the mode selector 3 and a second end 422 near the substrate 1. The blocking portion 41 as described above is arranged at the first end 421 of the first body portion 42 and protrudes toward the substrate 1.
In some embodiments, as shown in fig. 1 and 3, the substrate 1 comprises a second hole 11. Thus, as shown in fig. 1 and 5, the push lever 4 further includes a first actuating portion 43 disposed at the second end 422 of the first body portion 42. The first actuating portion 43 extends through the second aperture 11. The first actuation portion 43 will be driven by the status indicating member of the circuit breaker such that the push lever 4 can be moved between the first and second positions.
In some embodiments, as shown in fig. 1 and 5, the push lever 4 further includes a third aperture 44. Thus, as shown in fig. 1 and 6, the indicator 5 includes an indicating portion 51 and a first shaft 52. The indicating portion 51 is used to present the state of the circuit breaker (i.e., on state or off state). The first shaft 52 is connected to the indicating portion 51 and is disposed in the third hole 44. When the push lever 4 is moved in the second direction Z, the push lever 4 may drive the indicator 5 to rotate to assume the on state or the off state of the circuit breaker.
According to various embodiments of the present disclosure, the adjustment of the operating mode of the motor operator 100 is limited by the state of the circuit breaker, which is reflected by the position of the push lever 4. Specifically, when the push lever 4 is in the first position, the blocking portion 41 of the push lever 4 is located in the first hole 31 of the mode selector 3 to prevent the mode selector 3 from reaching the locked position. In addition, when the push lever 4 is in the second position, the blocking portion 41 of the push lever 4 is located outside the first hole 31 to allow the mode selector 3 to reach the locked position. In this way, the motor operator 100 can be prevented from entering the locked mode when the circuit breaker is in the on state. In other words, the motor operator 100 can be switched to the locking mode only when the circuit breaker is in the off state. In this way, the safety performance of the motor operator 100 is improved during use of the motor operator 100.
In some embodiments, as shown in fig. 1 and 2, the motor operator 100 further includes a locking lever 6. The locking lever 6 is rotatably coupled to the mounting plate 2 via a mounting pin 21. LOCK lever 6 may LOCK mounting plate 2 to base plate 1 when mode selector 3 is in LOCK position LOCK, and LOCK lever 6 may allow mounting plate 2 to be released from base plate 1 when mode selector 3 is in automatic position AUTO or manual position MAN. In this way, when the motor operator 100 is in the locked mode, the mounting plate 2, and thus the motor operator 100, may be prevented from being removed from the circuit breaker.
Fig. 7 shows a schematic view of the locking lever 6 of the motor operator 100 shown in fig. 1. In some embodiments, as shown in fig. 1 and 7, the locking lever 6 includes a second body portion 61, a second actuating portion 62, and a locking portion 63. The second body portion 61 is provided with a mounting hole 611, and the mounting pin 21 is disposed in the mounting hole 611. The locking lever 6 may be rotatably coupled to the mounting plate 2 using the mounting hole 611 and the mounting pin 21. The second actuating portion 62 is arranged at an end of the second body portion 61 close to the mode selector 3. When the mode selector 3 is switched from the automatic position AUTO or the manual position MAN to the LOCK position LOCK, the mode selector 3 may drive the second actuating portion 62 such that the second body portion 61 is rotated counterclockwise. The locking portion 63 is disposed at the other end of the second body portion 61. When the mode selector 3 is at the LOCK position LOCK, the LOCK portion 63 is locked to the substrate 1. When the mode selector 3 is at the automatic position AUTO or the manual position MAN, the locking portion 63 is unlocked from the base plate 1.
In some embodiments, as shown in fig. 1 and 4, the mode selector 3 further includes a drive portion 32. When the mode selector 3 is switched from the automatic position AUTO or the manual position MAN to the LOCK position LOCK, the driving portion 32 protrudes toward the base plate 1 to drive the second actuating portion 62 of the LOCK lever 6.
In some embodiments, as shown in fig. 1 and 2, the substrate 1 includes a restraining member 12. When the mode selector 3 is at the LOCK position LOCK, the restriction member 12 is used to catch the LOCK portion 63. In one example, as shown in fig. 1 and 3, the restriction member 12 is hook-shaped. In other examples, the restraining member 12 may be other shapes. The scope of the present disclosure is not limited in this respect.
In some embodiments, as shown in fig. 1 and 2, the motor operator 100 further comprises a spring 7. The spring 7 is used to reset the locking lever 6 when the locking lever 6 is not actuated by the mode selector 3. One end of the spring 7 is connected to the mounting plate 2 and the other end of the spring 7 is connected to the locking lever 6. With the spring 7, the locking lever 6 can return to its original position when the locking lever 6 is not driven by the mode selector 3.
In some embodiments, as shown in fig. 1 and 3, the mounting plate 2 may be provided with a second blocking member 23, the second blocking member 23 being for blocking the locking lever 4 when the locking lever 4 is reset by the spring 7. The locking lever 6 can return to its initial position under the action of the second blocking member 23 and the spring 7.
In some embodiments, the motor operator 100 further comprises a tag 8. The tag 8 is used to indicate the position of the mode selector 3. As shown in fig. 1, 2 and 8, tag 8 is provided with symbols "AUTO", "MAN" and "LOCK" for indicating an automatic position, a manual position and a LOCK position of mode selector 3, respectively.
Hereinafter, the operation mode of the motor operator 100 will be described with reference to fig. 9 to 14.
In fig. 9 and 10, the mode selector 3 is in the manual position MAN and the indicator 5 presents the on state of the circuit breaker. As shown, in this case, the blocking portion 41 is located in the first hole 21 of the mode selector 3. The selection handle 33 of the mode selector 3 can be placed only in the automatic position AUTO and the manual position MAN and cannot be moved to the LOCK position LOCK due to the blocking of the blocking portion 41. In this way, the motor operator 100 can be prevented from entering the locked mode when the circuit breaker is in the on state.
In fig. 11 and 12, the mode selector 3 is in the manual position MAN and the indicator 5 presents the off state of the circuit breaker. As shown, in this case, the blocking portion 41 is located outside the first hole 31. Accordingly, the selection handle 33 of the mode selector 3 can be moved to any one of the automatic position AUTO, the manual position MAN, and the LOCK position LOCK. In this way, the motor operator 100 can be switched to the locked mode only when the circuit breaker is in the off state.
In fig. 13 and 14, the mode selector 3 is in the locked position LOCK and the indicator 5 assumes the off state of the circuit breaker. As shown in the drawing, in this case, when the selection handle 33 of the mode selector 3 is moved to the LOCK position LOCK, the mode selector 3 pushes the LOCK lever 6 to rotate counterclockwise, so that the LOCK portion 63 of the LOCK lever 6 is locked by the restricting member 12. In this way, when the motor operator 100 is in the locked mode, the mounting plate 2, and thus the motor operator 100, may be prevented from being removed from the circuit breaker.
Fig. 15 shows a flow diagram of a method 1500 of manufacturing a motor operator for a circuit breaker according to an embodiment of the present disclosure.
As shown, at 1510, a substrate is provided. The base plate is adapted to be secured to a circuit breaker.
At 1520, a mounting plate is provided. The mounting plate is arranged substantially vertically on the base plate.
At 1530, a mode selector is provided. The mode selector is disposed on a side of the mounting plate away from the base plate, and is configured to be switchable along the side of the mounting plate in the first direction between an automatic position corresponding to an automatic operation mode of the motor operator, a manual position corresponding to a manual operation mode of the motor operator, and a lock position corresponding to a lock mode of the motor operator. The mode selector includes a first aperture extending in a first direction.
At 1540, a push lever is provided.
