For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] Reference Figure 1 , Figure 2 As shown, one aspect of the embodiment of the present application provides a mode conversion device, including a housing 11, a knob 23, a sliding member 24 and a padlock 25. The knob 23 and the sliding member 24 are arranged in linkage, and the sliding member 24 can be moved close to or away from the padlock 25 by the knob 23; the knob 23 has at least one of the manual, automatic and isolated position states, and the sliding member 24 is slidably mounted on the housing 11 to assist in achieving at least one of the manual, automatic and isolated states. When the knob 23 is in the isolated position, the padlock 25 is pulled out from the housing 11 to limit the movement of the sliding member 24, thereby limiting the knob 23 to the isolated position. When the knob 23 is in the manual or automatic position, the sliding member 24 cooperates with the housing 11 to enable the mode conversion device to be in the manual or automatic position to achieve manual or automatic operation.

[0051] The knob 23, the sliding member 24, and the padlock 25 are all arranged on the housing 11, wherein the sliding member 24 can be a sliding cover plate; the knob 23 is rotatably arranged on the housing 11, and can rotate relative to the housing 11, and the knob 23 has three position states: automatic, manual, and isolated by rotation; when the knob 23 switches between the three positions of automatic, manual, and isolated, it is linked with the sliding member 24 to drive the sliding member 24 to slide to the first position or to slide to the second position, and the sliding direction of the sliding member 24 is close to the padlock 25 or away from the padlock 25, so as to lock or unlock the padlock 25; when the knob 23 is in the three positions of automatic, manual, and isolated, respectively, the sliding member 24 is also in different positions corresponding to the three positions of automatic, manual, and isolated, respectively.

[0052] When the knob 23 is switched between the automatic, manual, and isolation positions, the slider 24 can open or close the operating hole 241 according to the different positions of the slider 24. The operating hole 241 is used to insert the handle 21 for manual operation. Only when the knob 23 is in the manual position, the slider 24 moves to the operating hole 241 open position, and manual operation can be performed at this time.

[0053] The padlock 25 can be pulled out only when the knob 23 is in the isolation position, and the sliding member 24 releases the restriction on the padlock 25. This is called padlock operation. When the padlock 25 is pulled out, the knob 23 cannot switch positions, that is, the knob 23 is restricted in the isolation position and cannot be switched to the automatic or manual position. At this time, the automatic transfer switch cannot be operated automatically or manually.

[0054] By padlocking, the automatic transfer switch can be restricted to the isolation mode, and the knob 23 cannot be operated in other modes; when the automatic transfer switch is in the isolation position, the automatic transfer switch is in a double-split state, at this time, the automatic transfer switch can be maintained and other operations can be performed to ensure the safety of maintenance personnel.

[0055] Therefore, in the mode conversion device provided by the embodiment of the present application, the knob 23 and the sliding member 24 are arranged in linkage, and the sliding member 24 can be driven to approach or move away from the padlock 25 by rotating the knob 23, so as to lock or unlock the padlock 25; the knob 23 has manual, automatic, and isolated position states. When the knob 23 is in the manual position, the sliding member 24 moves to the open state of the operation hole 241, and manual operation can be performed by inserting the handle 21 into the operation hole 241; when the knob 23 is in the automatic position, the sliding member 24 moves to the closed state of the operation hole 241, and automatic operation can be performed at this time; when the knob 23 is in the isolated position, the padlock 25 is pulled out from the housing 11 to limit the movement of the sliding member 24, and then the knob 23 is restricted to the isolated position, and the knob 23 cannot be automatically or manually operated. At this time, the automatic transfer switch is in a double-split state, and the automatic transfer switch can be repaired and other operations can be performed. The maintenance operation in the double-split state can ensure the safety of the maintenance personnel. The present application adopts a knob 23, a sliding member 24 and a padlock member 25 to realize switching between modes and complex interlocking logic, simplifies the structure, reduces the sense of stagnation during operation, and improves the convenience of operation; and realizes mode switching, padlocking and other functions through a minimum of parts, thereby reducing costs.

[0056] Furthermore, the knob 23 is rotatably arranged on the housing 11, and a first linkage part is formed on the knob 23; the sliding member 24 is slidably arranged in the housing 11, and a second linkage part is formed on the sliding member 24. Through the cooperation of the first linkage part and the second linkage part, the sliding member 24 is driven to move horizontally by the rotation of the knob 23, so that the sliding member 24 is in at least one of the manual, automatic, and isolation states with the knob 23. That is to say, when the knob 23 is in the manual, automatic, and isolation positions, respectively, the sliding member 24 is also in different positions, respectively.

[0057] For example, Figure 4 As shown, the knob 23 has a flat cylindrical mounting portion 231, the mounting portion 231 is pivotally connected to the housing 11, the first linkage portion includes an extension shaft 230 provided on the knob 23, the extension shaft 230 is located on one side of the mounting portion 231, and a columnar indicating portion 232 is also provided on the other side of the mounting portion 231, the indicating portion 232 is used to indicate the position state of the knob 23; the indicating portion 232 is located on the housing 11, and the extension shaft 230 extends into the housing 11. As for the sliding member 24, its second linkage portion includes a linkage groove 240 provided on the sliding member 24, the linkage groove 240 is a long strip groove, and the extension shaft 230 of the knob 23 extends into the linkage groove 240 of the sliding member 24 for matching.

[0058] like Figure 3As shown, the knob 23 is rotatably mounted on the housing 11, and the extension shaft 230 passes through the housing 11 and extends into the linkage slot 240; when the knob 23 is rotated, the extension shaft 230 cooperates with the linkage slot 240 to drive the sliding member 24 to move horizontally in a direction parallel to the upper surface of the housing 11, so that the sliding member 24 approaches the padlock member 25 or moves away from the padlock member 25.

[0059] Among them, Figure 5 As shown, the center line of the extension shaft 230 and the mounting portion 231 deviates from the center line of the indicator portion 232. The mounting portion 231 is cylindrical, and the line between the axis of the extension shaft 230 and the center (center of the circle) of the circular cross section of the mounting portion 231 is at an angle to the center line of the indicator portion 232, that is, the two do not overlap. This arrangement allows the extension shaft 230 to be offset from the center line of the knob 23, making it easier to match the position of the sliding member 24, so as to drive the sliding member 24 to move horizontally and to work in conjunction with the padlock 25.

[0060] like Figure 6 As shown, the operating hole 241 is provided on the sliding member 24, and the housing 11 is provided with a window 11a corresponding to the operating hole 241. When the knob 23 is in the manual position, the operating hole 241 of the sliding member 24 is located at Figure 1 At a corresponding position of the middle handle hole 11b, the operation hole 241 is opened, so that the handle 21 is inserted into the operation hole 241 through the handle hole 11b and linked with the hand-operated device.

[0061] For example, the operating hole 241 is a long hole arranged on the sliding member 24, and a circular window 11a is provided on the shell 11. When the knob 23 is rotated to the manual position, the operating hole 241 of the sliding member 24 is driven to move to the position corresponding to the window 11a. At the same time, a manual hole 223 is also provided on the hand-operated device in the shell 11, and the operating hole 241 of the sliding member 24 corresponds to the manual hole 223 at the same time. In this way, the handle 21 can pass through the handle hole 11b on the shell 11, the operating hole 241 of the sliding member 24, and the manual hole 223 of the hand-operated device in sequence to drive the hand-operated device to move and complete manual operation.

[0062] The padlock 25 is slidably arranged in the housing 11 so that when the knob 23 is in the isolation position, the padlock 25 can be pulled out of the housing 11; a first locking portion is arranged on the padlock 25, and a second locking portion is arranged on the sliding member 24. The first locking portion and the second locking portion cooperate to achieve the locking of the padlock 25, and in the manual or automatic state, the sliding member 24 restricts the padlock 25; in the isolation state, the padlock 25 is pulled out of the housing 11 to restrict the movement of the sliding member 24, thereby restricting the knob 23 in the isolation position.

[0063] The padlock 25 can slide in a direction perpendicular to the upper surface of the housing 11 , that is, the sliding direction of the padlock 25 is perpendicular to the moving direction of the sliding member 24 .

[0064] When the sliding member 24 is driven by the knob 23 to move horizontally to approach the padlock 25, the first locking portion of the padlock 25 and the second locking portion of the sliding member 24 cooperate to lock the padlock 25. At this time, the padlock 25 cannot move and cannot be pulled out of the housing 11; when the sliding member 24 is driven by the knob 23 to move a certain distance away from the padlock 25, the sliding member 24 can gradually release the restriction on the padlock 25, and then when the restriction is completely released, the padlock 25 can be pulled out of the housing 11 to limit the movement of the sliding member 24, thereby limiting the knob 23 to the isolation position.

[0065] Specifically, Figure 7 As shown, the first locking portion includes a groove 251 provided on the padlock 25, and the second locking portion includes a protruding rod 242 provided on the sliding member 24. The protruding rod 242 is provided along the moving direction of the sliding member 24, and the protruding rod 242 extends into the groove 251 to lock the padlock 25.

[0066] In one embodiment, Figure 6 , Figure 7 As shown, the padlock 25 is a flat plate structure, and grooves 251 are formed on both sides of the flat plate structure. Two protruding rods 242 extend from the sliding member 24, and the protruding rods 242 are arranged toward the padlock 25. When the sliding member 24 moves toward the padlock 25, the two protruding rods 242 of the sliding member 24 extend into the two grooves 251 of the padlock 25 to lock the padlock 25, thereby limiting the movement of the padlock 25, and the padlock 25 cannot be pulled out, and the padlocking operation cannot be performed.

[0067] On the other hand, the padlock 25 has a padlock surface 250 facing the sliding member 24, and the groove 251 passes through the side wall of the padlock 25 perpendicular to the padlock surface 250 from the padlock surface 250; when the knob 23 is in the isolation position, the sliding member 24 moves in the direction away from the padlock 25, the protruding rod 242 disengages from the groove 251, and the padlock 25 can be pulled out of the housing 11. When the end of the protruding rod 242 is in a state of abutting against the padlock surface 250, the movement of the sliding member 24 is restricted, thereby restricting the knob 23 in the isolation position.

[0068] The surface of the padlock 25 facing the sliding member 24 is defined as a padlock surface 250 . The notch of the groove 251 is located on the padlock surface 250 . The depth of the groove 251 is the thickness of the side wall perpendicular to the padlock surface 250 . That is, the groove 251 passes through the side wall of the padlock 25 .

[0069] When the sliding member 24 moves toward the padlock 25, the two protruding rods 242 of the sliding member 24 extend into the two grooves 251 of the padlock 25 respectively, locking the padlock 25, and preventing the padlock operation. When the sliding member 24 moves away from the padlock 25, the protruding rod 242 escapes from the groove 251. After escaping, the padlock 25 can be pulled upward to perform the padlock operation. At this time, after the protruding rod 242 has just escaped from the groove 251 and the padlock 25 is pulled upward, the end of the protruding rod 242 is still in a state of abutting against the padlock surface 250 of the padlock 25. After the padlock 25 is pulled out of the housing 11, the movement of the sliding member 24 is restricted, and the knob 23 is further restricted in the isolation position. The padlock operation restricts the knob 23 in the isolation position.

[0070] When unlocking is required, the padlock 25 is pressed down to the initial position, and the knob 23 is rotated to drive the sliding member 24 to move toward the padlock 25 again. When the protruding rod 242 extends into the groove 251, the padlock 25 is locked again.

[0071] At least one protrusion 242 and at least one groove 251 are respectively provided. For example, in the present application, two protrusions 242 and two grooves 251 are respectively provided. The two grooves 251 are respectively located on two opposite side walls of the padlock 25. The sliding member 24 clamps the padlock 25 by the cooperation of the two protrusions 242 and the two grooves 251.

[0072] When the two protruding rods 242 extend into the two grooves 251 , the sliding member 24 is equivalent to clamping the padlock 25 to stably lock the padlock 25 .

[0073] In summary, the mode conversion device provided in the embodiment of the present application adopts a knob 23, a sliding member 24, and a padlock 25. The knob 23 has three positions: automatic, manual, and isolated. When the knob 23 switches between the three positions, the knob 23 is linked with the sliding member 24 to drive the sliding member 24 to slide to the first position or to the second position. When the knob 23 is in the three positions of automatic, manual, and isolated, the sliding member 24 is also in different positions. The sliding member 24 can open or close the operating hole 241 when the knob 23 switches between the three positions of automatic, manual, and isolated. The operating hole 241 is opened only when the knob 23 is in the manual position. The padlock 25 can be pulled out only when the knob 23 is in the isolated position, and when pulled out, the knob 23 cannot switch positions.

[0074] The knob 23 is pivotally mounted on the housing 11, and the knob 23 is linked with the sliding member 24 to drive the sliding member 24 to slide under the action of an external force; when the knob 23 rotates in a first direction, it first drives the sliding member 24 to move in the first direction to reach a neutral point (the extreme position of the sliding member 24 moving in the first direction) and then moves in the second direction; when the knob 23 rotates in the second direction, it first drives the sliding member 24 to move in the second direction to reach a neutral point (the extreme position of the sliding member 24 moving in the second direction) and then moves in the first direction.

[0075] For example, Figure 8a to Figure 9b As shown, when the knob 23 is rotated clockwise, it passes through the automatic, manual and isolation positions in sequence, and the sliding member 24 moves toward the padlock member 25 when the knob 23 is in the automatic and manual positions; Figure 8a , Figure 8b When the middle knob 23 is in the automatic position, the protruding rod 242 of the sliding member 24 extends into the groove 251 of the padlock member 25 to lock; Figure 9a , Figure 9b When the middle knob 23 is in the manual position, the protruding rod 242 of the sliding member 24 extends deeper into the groove 251 of the padlock 25 until the end of the protruding rod 242 exceeds the groove 251, and the sliding member 24 and the padlock 25 are locked more deeply. At this time, the manual position of the knob 23 is the limit position of the sliding member 24 moving toward the first direction (the direction of movement of the sliding member 24 toward the padlock 25).

[0076] When the knob 23 is rotated from the manual position to the isolation position, Fig.10a , Fig.10b As shown, the sliding member 24 moves in the opposite direction toward the second direction, that is, the sliding member 24 moves in the direction away from the padlock 25. When in the isolation position, the protruding rod 242 of the sliding member 24 just escapes from the groove 251 of the padlock 25. This is the limit position of the sliding member 24 moving in the second direction. The padlock 25 can be pulled out, and the padlock surface 250 and the end of the protruding rod 242 abut against each other. After the padlock 25 is pulled out of the housing 11, the movement of the sliding member 24 is limited, and the knob 23 is further limited in the isolation position. After the padlock 25 is pressed back to the initial position, the protruding rod 242 of the sliding member 24 can gradually move toward the direction close to the padlock 25 until it extends into the groove 251 of the padlock 25. At this time, the knob 23 can continue to be rotated.

[0077] For the sliding member 24, the sliding member 24 is horizontally slidably installed in the housing 11. The protruding rod 242 provided on the sliding member 24 can limit the movement of the padlock member 25. When the protruding rod 242 of the sliding member 24 escapes from the groove 251 of the padlock member 25, the padlock member 25 can be pulled out. After the padlock member 25 is pulled out, the protruding rod 242 of the sliding member 24 abuts against the padlock surface 250 of the padlock member 25 to limit the sliding of the sliding member 24.

[0078] The padlock 25 is vertically slidably installed in the housing 11. The first locking portion (groove 251) provided on the padlock 25 can be locked by the second locking portion (protruding rod 242) of the sliding member 24, thereby limiting the movement of the padlock 25. After the protruding rod 242 of the sliding member 24 escapes from the groove 251 of the padlock 25, the padlock 25 can be pulled out. At this time, the padlock surface 250 of the padlock 25 and the protruding rod 242 of the sliding member 24 can abut against each other to limit the movement of the sliding member 24, thereby limiting the knob 23 in the isolation position.

[0079] When the protruding rod 242 of the sliding member 24 abuts against the padlock surface 250 of the padlock member 25, the padlock member 25 is pulled out, the sliding member 24 is located at the extreme position of movement away from the padlock member 25, and the knob 23 is limited to the isolation position; after the padlock member 25 is pressed back, the protruding rod 242 of the sliding member 24 extends into the groove 251, and the knob 23 gradually rotates to the manual and automatic positions. When the knob 23 is in the manual position, the protruding rod 242 extends into the groove 251 to the maximum stroke, and the sliding member 24 is at the extreme position of movement close to the padlock member 25.

[0080] The knob 23, the sliding member 24 and the padlock 25 are used to realize the mode switching and padlocking functions with the least number of parts. The padlock 25 is locked and pulled out from the housing 11 to limit the movement of the sliding member 24, thereby limiting the knob 23 in the isolation position. The sliding member 24 and the padlock 25 are provided with matching locking parts for positioning and limiting, thereby realizing complex interlocking logic and reducing costs. The design language is consistent with that of the NDQ5 series products. The rotational friction resistance is small, the sticking feeling is small, and the operation is convenient.

[0081] The above mode conversion device can be applied to automatic transfer switch. On this basis, please refer to Figure 3 As shown, the automatic transfer switch also includes a manual operating device and an operating mechanism linked with the manual operating device. The manual operating device includes a manual operating member 22. The manual operating device and the gear member 12 of the operating mechanism are linked. The operating mechanism is used to connect with the contact device 30 to drive the contact device 30 to open and close. A manual operating hole 223 is set on the manual operating device. When the knob 23 is rotated to the manual position, the operating hole 241 of the sliding member 24 is driven to move to correspond to the handle hole 11b on the housing 11 and the manual operating hole 223 of the manual operating device. The handle 21 passes through the handle hole 11b on the housing 11, the operating hole 241 of the sliding member 24, and the manual operating hole 223 of the manual operating device in sequence. The manual operating device can be driven to rotate through the handle 21, and then the gear member 12 is driven to rotate to drive the contact device 30 to open and close, completing the function of manual operation of opening and closing.

[0082] Furthermore, the automatic transfer switch is also provided with a limiting device for limiting the knob 23 .

[0083] The automatic transfer switch has at least three position states: normal closing, standby closing, and double separation. The limit device of the automatic transfer switch includes a knob 23 and a knob limiter that cooperate with each other. The knob 23 is used to switch the automatic transfer switch between the automatic position, the manual position, and the isolation position. The knob limiter is used to limit the knob 23 when the automatic transfer switch is in the normal power closing and the standby power closing state, so as to limit the knob 23 to the automatic position or the manual position.

[0084] The operating mechanism is used to connect with the contact device 30. Under the drive of external force, the contact device 30 can be in three states: normal closing, double opening, and standby closing. The hand-operated device rotates a certain angle when the contact device 30 switches between normal closing, double opening, and standby closing. When the contact device 30 is in the normal closing, double opening, and standby closing states, the hand-operated device is located at different angles. The knob limiter limits the knob 23 in the normal power closing and standby power closing states, and the knob 23 cannot be rotated to the isolation position. When the knob limiter does not limit the knob 23, the knob 23 can be switched to the isolation position.

[0085] For example, Fig.11 , Fig.12 As shown, the knob limiter includes a hand-operated member 22 pivotally disposed in the housing 11 , the hand-operated member 22 is linked to the operating mechanism of the automatic transfer switch, the operating mechanism is used to connect the contact device 30 , and the knob 23 is pivotally disposed on the housing 11 .

[0086] The hand-operated device includes a hand-operated member 22, which can also serve as a knob limiter to limit the knob 23. The housing 11 is provided with a mounting hole, and the knob 23 is pivotally arranged on the housing 11 through the mounting hole.

[0087] The knob 23 is disposed on the upper surface of the housing 11 , and the knob 23 is disposed parallel to the housing 11 ; the hand operating piece 22 is disposed perpendicular to the housing 11 , and the rotating surface of the hand operating piece 22 and the rotating surface of the knob 23 are perpendicular to each other.

[0088] The hand-operated piece 22 is provided with a limiting portion, and the knob 23 is provided with an extension shaft 230 extending into the housing 11 . The hand-operated piece 22 limits the knob 23 through the abutment between the extension shaft 230 and the limiting portion.

[0089] The extension shaft 230 of the knob 23 is also used to drive the sliding member 24 to slide. After the extension shaft 230 extends into the housing 11, the knob 23 can be limited or released by cooperating with the limiting portion of the hand-operated member 22.

[0090] The limiting portion includes a first limiting platform 22a and a second limiting platform 22b protruding 252 from the first surface of the hand-operated member 22, and the extension shaft 230 is limited by the first limiting platform 22a and the second limiting platform 22b respectively.

[0091] A protrusion 252 is formed on the first surface of the hand-operated member 22 facing the extension shaft 230. The protrusion 252 includes a first limiting platform 22a and a second limiting platform 22b. Fig.11 As shown, when the automatic transfer switch is in the state of normal power on, the inner wall of the first limit platform 22a facing the second limit platform 22b abuts against the extension shaft 230 to limit the extension shaft 230 from moving toward the isolation position.

[0092] At this time, the knob 23 can be rotated clockwise to switch between the automatic position and the manual position, but due to the abutment of the inner wall of the first limit platform 22a, the knob 23 cannot be rotated counterclockwise toward the isolation position.

[0093] like Fig.12 As shown, when the automatic transfer switch is in the standby power on state, the outer wall of the second limit platform 22b away from the first limit platform 22a abuts against the extension shaft 230 to limit the extension shaft 230 from moving toward the isolation position.

[0094] Similarly, at this time, the knob 23 can be rotated clockwise to switch between the automatic position and the manual position, but due to the support of the outer wall of the second limit platform 22b, the knob 23 cannot be rotated counterclockwise toward the isolation position.

[0095] like Fig.13 As shown, when the automatic conversion switch is in the double-open state, the movement trajectory of the extension shaft 230 is away from the first limit platform 22a and the second limit platform 22b, so that the knob 23 can be switched arbitrarily between the automatic position, the manual position and the isolation position.

[0096] At this time, the movement track of the knob 23 avoids the first limit platform 22a and the second limit platform 22b, and the knob 23 can be turned arbitrarily to realize the switching among the automatic position, the manual position and the isolation position.

[0097] Through the above arrangement, when the hand-operated device is in the state of the normal power supply being closed and the standby power supply being closed, the knob 23 cannot be rotated to the isolation position, thereby preventing the erroneous operation of the knob 23 from affecting the normal operation of the automatic transfer switch.

[0098] On the other hand, as mentioned above, the padlocking operation can be performed through the padlock 25 to limit the automatic transfer switch to the isolation mode, and the knob 23 cannot be operated in the manual or automatic mode; when the automatic transfer switch is in the isolation position, the automatic transfer switch is in a double-split state, at this time, the automatic transfer switch can be maintained and other operations can be performed to ensure the safety of the maintenance personnel.

[0099] To further improve the safety of padlock operation, the automatic transfer switch also includes a padlock locking device, which includes a padlock member 25 and a locking member that cooperates with the padlock member 25, so as to limit the padlock member 25 when the automatic transfer switch is in the normal power closing state and the standby power closing state; when the automatic transfer switch is in the double-open position, the limit on the padlock member 25 is released, and the padlock member 25 can be pulled out from the housing 11 for padlock operation.

[0100] In one embodiment of the present application, Fig.14 As shown, the locking member includes an indicator 220 for indicating the state of the actuator 10 , and the indicator 220 and the actuator 10 are linked.

[0101] In one embodiment, the indicator 220 and the hand-operated piece 22 are integrally arranged. When the hand-operated piece 22 rotates, the indicator 220 is driven to rotate synchronously. Three indication areas are formed on the indicator 220, which are a common closing area, a double partition area or a standby closing area. The three indication areas can be displayed through the window 11a on the shell 11 to indicate the current state of the hand-operated piece 22.

[0102] Driven by external force, the actuator 10 corresponds to the contact device 30, which can be in three states: normal closing, double opening, and standby closing; the indicator 220 rotates a certain angle when the driving mechanism switches between normal closing, double opening, and standby closing. When the actuator 10 is in the normal closing, double opening, and standby closing states, the indicator 220 is located at different angles to indicate the corresponding state.

[0103] like Fig.15 As shown, the padlock 25 is slidably arranged in the shell 11 along a vertical direction perpendicular to the upper surface of the shell 11, and the padlock 25 can slide in a direction perpendicular to the upper surface of the shell 11; the indicator 220 is pivotally arranged in the shell 11, and the padlock 25 and the indicator 220 are arranged in parallel.

[0104] The padlock 25 can be pulled out or pressed back in a vertical direction perpendicular to the upper surface of the housing 11. The indicator 220 and the hand-operated member 22 are integrally pivoted in the housing 11, and the hand-operated member 22 and the indicator 220 can be driven to rotate by rotating the handle 21. Although the indicator 220 can rotate in the housing 11, the indicator 220 and the padlock 25 are parallel to each other.

[0105] The indicator 220 is provided with a first limiting portion 220a, and the padlock 25 is provided with a second limiting portion. The padlock 25 is limited or released through the cooperation between the first limiting portion 220a and the second limiting portion.

[0106] For example, Fig.15As shown, the first limiting portion 220a is located at the bottom of the indicator 220 and below the indicating area. The indicator 220 cooperates with the second limiting portion of the padlock 25 through the first limiting portion 220a. The indicator 220 can limit or release the movement of the padlock 25 in a direction perpendicular to the upper surface of the shell 11.

[0107] When the first limit portion 220a on the indicator 220 is in the middle position (i.e., when the indicator 220 rotates to the indicating area of ​​the middle position on the indicator 220 and can be shown by the housing 11, i.e., when the actuator 10 is in the double-split state), it does not limit the padlock 25, and the padlock 25 can be pulled out; when the indicator 220 is in the normal power closing state and the backup power closing state, it limits the padlock 25, and the padlock 25 cannot be pulled out of the padlock. In other words, when the normal power closing state and the backup power closing state are in place, the padlock operation cannot be performed.

[0108] Specifically, the first limiting portion 220a is provided with a slide groove 220b, and the second limiting portion includes a protrusion 252. For example, the protrusion 252 is located at the bottom end of the padlock 25. When the actuator 10 is in the double-split state, the indicator 220 rotates to the matching position of the slide groove 220b and the protrusion 252. Pulling the padlock 25 can make the protrusion 252 move along the slide groove 220b, so as to limit the working mode of the automatic transfer switch to the isolation position, such as Fig.16 shown.

[0109] When the indicator 220 rotates until the slide groove 220b and the protrusion 252 of the padlock member 25 are aligned, the padlock member 25 is pulled to perform the padlock operation, and the protrusion 252 of the padlock member 25 moves upward along the slide groove 220b. The indicator 220 cannot rotate because the protrusion 252 is restricted in the slide groove 220b. At this time, the padlock operation can restrict the knob 23 to the isolation position, and the knob 23 cannot be operated manually or automatically.

[0110] The slide groove 220b is arranged along the vertical direction when the actuator 10 is in the double-split state, and the notch of the slide groove 220b is located at the bottom of the indicator 220, and the bottom of the slide groove 220b is used to limit the sliding of the padlock 25 along the vertical direction.

[0111] The slot opening of the slide groove 220b is located at the bottom and the bottom of the slot is located at the top, and the padlocking operation is performed when the protrusion 252 moves upward along the slide groove 220b; when the protrusion 252 slides upward to the bottom of the slide groove 220b, the protrusion 252 cannot continue to move upward, and the upward movement of the padlock 25 is limited.

[0112] When the padlock 25 is pressed down, the protrusion 252 is disengaged from the slide groove 220b. At this time, when the hand-operated member 22 is rotated to drive the indicator 220 to rotate, the protrusion 252 and the slide groove 220b are not in contact, and the padlock 25 does not affect the rotation of the indicator 220, and the two are released from the limit.

[0113] The manual operating member 22 drives the indicating member 220 to continue to rotate. When the actuator 10 is in the normal closing state or the standby closing state, the first limiting portion 220 a and the second limiting portion abut against each other to limit the padlock member 25 .

[0114] like Fig.15 As shown, when the actuator 10 is in the normal closing state or the standby closing state, the indicator 220 rotates until the protrusion 252 slides out of the slide groove 220b. When the padlock 25 is to be pulled upward, the protrusion 252 of the padlock 25 and the outer periphery of the indicator 220 (that is, the outer periphery of the first limit portion 220a) abut against each other to limit the sliding of the padlock 25, that is, the padlock 25 cannot be pulled out and the padlocking operation cannot be performed.

[0115] After the protrusion 252 slides out of the slide groove 220b, the indicator 220 can be rotated by the hand-operated member 22. At this time, since the slide groove 220b rotates to a position deviating from the protrusion 252, the protrusion 252 cannot enter the slide groove 220b, so that the padlock member 25 is restricted by the indicator 220, and the padlock member 25 cannot move upward to be padlocked, thereby limiting the padlock member 25; that is, the padlocking operation cannot be performed in the normal closing state and the standby closing state.

[0116] The padlocking operation can be performed only when the hand-operated member 22 drives the indicator member 220 to rotate to the double-open position, the slide groove 220b and the protrusion 252 are aligned, the protrusion 252 extends into the slide groove 220b and moves upward along the slide groove 220b, and the padlock member 25 is pulled out.

[0117] When the protrusion 252 of the indicator 220 slides out of the slide slot 220b, the height between the protrusion 252 and the horizontal plane is smaller than the height between the notch of the slide slot 220b and the horizontal plane.

[0118] That is to say, when the protrusion 252 slides out of the slide groove 220b, the protrusion 252 is lower than the position of the slot of the slide groove 220b. In this way, the protrusion 252 and the slide groove 220b are not in contact, and there is no limiting relationship between the padlock component 25 and the indicator component 220. The indicator component 220 can be rotated by the hand-operated component 22 without being restricted by the padlock component 25.

[0119] On the basis of the above, if Fig.17 As shown, an embodiment of the present application also discloses an automatic transfer switch, including a mode conversion device as described above.

[0120] The automatic transfer switch has the same structure and beneficial effects as the mode conversion device in the above-mentioned embodiment.
