Description

withdrawal device

[0001] The present invention relates to a draw-out device, and more particularly, to a draw-out device that can be easily combined and separated from a distribution frame, can be combined at an accurate position, can perform a plurality of operations related to the drawing-out and drawing-out of a circuit breaker, and can perform the above process safely.

[0002] A distribution board is a device that receives electricity from an external power source and transmits it to loads according to the system or purpose. The distribution board is connected to external power sources and loads, thereby energizing them.

[0003] To prevent potential power failures between external power sources and loads, distribution panels are typically equipped with circuit breakers. These circuit breakers are connected to the external power source and load, respectively, and are designed to interrupt abnormal currents. This prevents these power failures.

[0004] If a current interruption operation is performed, the circuit breaker's components may require replacement. Furthermore, it may be necessary to remove the circuit breaker from the distribution panel for maintenance. Therefore, circuit breakers are typically detachably mounted on the distribution panel.

[0005] Meanwhile, the size of switchboards and circuit breakers tends to be proportional to their rated capacity. That is, when a larger current flows, the size of the circuit breaker to interrupt it may increase. Consequently, the size of the switchboard to which the circuit breaker is connected may also increase. Consequently, a significant force is required to attach or detach the circuit breaker from the switchboard.

[0006] However, in the case of traditional switchboards and circuit breakers, the process of connecting and disconnecting the circuit breakers is performed manually. That is, this process is typically performed by a worker. In the above case, the worker is positioned adjacent to the switchboard and circuit breakers and manually connects or disconnects the circuit breakers.

[0007] Meanwhile, arcs can occur when circuit breakers electrically connect and disconnect with the distribution board. Arcs are formed by a momentary flow of high-temperature, high-voltage electrons, posing a potentially fatal hazard to workers.

[0008] Therefore, it is desirable that the process of inserting and withdrawing a circuit breaker into or out of a distribution panel be performed remotely, as far away from the circuit breaker or distribution panel as possible.

[0009] Korean Patent Document No. 10-1733705 discloses a distribution panel equipped with a vacuum circuit breaker insertion / withdrawal safety device. Specifically, the distribution panel is equipped with a vacuum circuit breaker insertion / withdrawal safety device, which includes a locking groove on the underside of a transport truck on which a vacuum circuit breaker is mounted, and a horizontal plate provided on a cradle that locks or releases the locking groove, thereby preventing arbitrary movement of the vacuum circuit breaker.

[0010] However, the distribution panel equipped with a vacuum circuit breaker entry / exit safety device disclosed in the above-mentioned prior art document assumes that the vacuum circuit breaker is manually inserted / exited into the distribution panel. In other words, the above-mentioned prior art document does not provide a method for automatically performing the insertion / exit process of the vacuum circuit breaker remotely.

[0011] Korean Patent No. 10-1912449 discloses a high-voltage switchboard with a remote racking system. Specifically, the document discloses a high-voltage switchboard with a remote racking system that allows circuit breakers within the switchboard to be remotely removed or inserted.

[0012] However, the high-voltage switchboards utilizing the remote racking system disclosed in the above-mentioned prior art require actuators for circuit breakers to be installed within the high-voltage switchboards. This means that additional motors are installed within the high-voltage switchboards, which contain complex and diverse configurations, and a complex wiring structure is additionally required to control them.

[0013] Furthermore, the remote racking system disclosed in the aforementioned prior art document has complex conditions for circuit breakers to be moved. Therefore, precisely inputting control signals for circuit breakers' insertion or withdrawal makes it difficult for the circuit breakers to be inserted or withdrawn smoothly.

[0231] A pair of coupling grooves (323) extend in the longitudinal direction of the profile body (321), i.e., in the front-back direction. Each end of the coupling grooves (323) in the extending direction is formed open. The power unit (20) can move along the coupling grooves (323) while the power fixing member (640) is at least partially accommodated in the coupling grooves (323).

[0232] The number and arrangement of the coupling grooves (323) can be changed depending on the number and arrangement of the power fixing members (640).

[0234] A power stopper (650) provided in the power unit (20) is inserted into the fixing hole (324) so ​​as to be withdrawable. When the power stopper (650) is inserted into the fixing hole (324), further movement of the power unit (20) in the extension direction of the profile body (321), i.e., the front-back direction, is restricted. Thereafter, when the power fixing member (640) is manipulated and the core (not given a drawing symbol) is inserted into the joining groove (323), the position of the power unit (20) can be fixed.

[0235] A fixing hole (324) is formed by penetrating or recessing into one surface of the profile body (321).

[0237] The fixed hole (324) can be positioned at a predetermined distance from one end of the limiting plate (130) opposite to the distribution frame (2), the front end in the illustrated embodiment.

[0238] Additionally, the position of the fixed hole (324) can be determined to correspond to the position of the power stopper (650) when the first support bracket (611) of the power unit (20) comes into contact with the first limiting plate (131).

[0239] In one embodiment, the distance between the fixing hole (324) and the front end of the first limiting plate (131) may be greater than or equal to the distance between the power stopper (650) and the front end of the first limiting plate (131) when the first support bracket (611) of the power unit (20) contacts the first limiting plate (131).

[0240] Accordingly, the distance at which the power unit (20) is inserted into the bracket unit (10) can be doubly limited by the limit plate (130) and the fixing hole (324). Accordingly, the power unit (20) can be stably positioned at a preset position and then fixed.

In the illustrated embodiment, the second bracket plate (622) is formed in a polygonal shape having a length in the front-back direction, a height in the vertical direction, and a width in the left-right direction.

[0324] The second bracket plate (622) is coupled to the first bracket plate (621). In the illustrated embodiment, the upper ends of the pair of second bracket plates (622) are continuous with the left and right ends of the first bracket plate (621) at a predetermined angle, respectively. In one embodiment, the first bracket plate (621) and the second bracket plate (622) may be formed integrally.

[0325] The second bracket plate (622) is coupled with the first support bracket (611). At this time, one side of the second bracket plate (622) in the height direction, the lower end in the illustrated embodiment, is bent outward in the width direction so as to be coupled with the first support bracket (611).

[0326] The second bracket plate (622) is coupled with the guide rail (630). Specifically, the guide rail (630) is coupled to one side of the second bracket plate (622) facing the bracket receiving space (623), i.e., the inner side in the width direction.

[0327] The bracket receiving space (623) movably receives the guide profile (320). The power unit (20) can be moved toward the distribution frame (2) or in the opposite direction, i.e., toward the front side or the rear side, while the guide profile (320) is received in the bracket receiving space (623).

[0328] The bracket receiving space (623) may be formed to correspond to the shape of the guide profile (320). In the illustrated embodiment, the bracket receiving space (623) is formed to have a length in the left-right direction, a width in the front-back direction, and a height in the up-down direction. At this time, as described above, the length of the bracket receiving space (623) in each direction may be formed to be less than or equal to the length of the guide profile (320) in each direction.

[0329] The bracket receiving space (623) is defined by being surrounded by the first support bracket (611), the first bracket plate (621), and the second bracket plate (622). Each side of the width direction of the bracket receiving space (623), the front side and the rear side in the illustrated embodiment, are formed as open. The guide profile (320) can be received, withdrawn, and moved into the bracket receiving space (623) through each of the sides.

[0330] A power fixing member (640) is movably connected to the fixed member connecting hole (624). The fixed member connecting hole (624) is formed to penetrate the first bracket plate (621). The power fixing member (640) can be moved in the direction toward and opposite to the guide profile (320) accommodated in the bracket receiving space (623) by penetrating the fixed member connecting hole (624).

[0331] The fixed member joining hole (624) can be formed to correspond to the shape of the power fixed member (640). In the illustrated embodiment, the fixed member joining hole (624) is formed as a space in the shape of a disk having a circular cross-section and a thickness in the vertical direction.

[0332] A plurality of fixed member connecting holes (624) may be formed. The plurality of fixed member connecting holes (624) may be spaced apart from each other. In the illustrated embodiment, the fixed member connecting holes (624) are configured to include one pair positioned to the left and another pair positioned to the right.

[0333] At this time, the pair of fixed member connecting holes (624) may be positioned vertically above the connecting groove (323) located on the left side. In addition, the other pair of fixed member connecting holes (624) may be positioned vertically above the connecting groove (323) located on the right side.

[0334] A stopper joint (625) is positioned between a plurality of fixed member joints (624).

[0335] A power stopper (650) is movably connected to the stopper coupling hole (625). The stopper coupling hole (625) is formed to penetrate the first bracket plate (621). The power stopper (650) can be moved in the direction toward and in the opposite direction to the guide profile (320) accommodated in the bracket accommodation space (623) by penetrating the stopper coupling hole (625).

[0336] The stuffer coupling hole (625) can be formed to correspond to the shape of the power stuffer (650). In the illustrated embodiment, the stuffer coupling hole (6250) is formed as a space in the shape of a disk having a circular cross-section and a thickness in the vertical direction.

[0337] The stopper coupling hole (625) may be positioned adjacent to the center of the first bracket plate (621). In other words, the distance between each vertex of the first bracket plate (621) based on the stopper coupling hole (625) may be formed to be the same. At this time, when the power unit (20) is moved to a preset position in the bracket unit (10), the stopper coupling hole (625) may be positioned vertically above the fixing hole (324).

[0338] The guide rail (630) is movably inserted into the guide groove (322). In one embodiment, the guide rail (630) can be slidably inserted into the guide groove (322). In the illustrated embodiment, the guide rail (630) is movably inserted into the guide groove (322) in the extension direction of the guide profile (320), i.e., in the forward and backward direction.

[0339] The guide rail (630) inserted into the guide groove (322) is restricted from moving in any direction other than its own direction of movement, i.e., in the left-right and up-down directions in the illustrated embodiment. Accordingly, the power unit (20) can be moved in the extension direction of the guide profile (320), i.e., in the forward-backward direction, while being prevented from swinging in the left-right or up-down directions.

[0340] As a result, the relative movement of the power unit (20) with respect to the bracket unit (10) can proceed stably.

[0341] The guide rail (630) is inserted into the guide groove (322), and may have any shape that can prevent up-down or left-right movement. In the illustrated embodiment, the guide rail (630) is formed such that the height of the inner portion in the width direction is longer than the height of the middle portion in the width direction. The shape of the guide rail (630) may be changed to correspond to the shape of the guide groove (322).

[0342] The guide rail (630) is coupled to the second bracket plate (622). The guide rail (630) is located on one side of the second bracket plate (622) facing the bracket receiving space (623), i.e., on the inner surface in the thickness direction. The guide rail (630) is located in the bracket receiving space (623).

[0343] A plurality of guide rails (630) may be provided. The plurality of guide rails (630) may be spaced apart from each other and may be respectively coupled to a plurality of second bracket plates (622). In the illustrated embodiment, a pair of guide rails (630) are provided and are respectively positioned on the inner surface of a pair of second bracket plates (622). The pair of guide rails (630) are spaced apart from each other in the longitudinal direction of the bracket receiving space (623), and in the left-right direction in the illustrated embodiment.

[0344] The number and arrangement of guide rails (630) may be changed depending on the number and arrangement of guide grooves (322).

[0345] The power fixing member (640) is retractably received in the coupling groove (323). When the power fixing member (640) is sufficiently received in the coupling groove (323), the power fixing member (640) presses against the surface of the profile body (321) surrounding the coupling groove (323). Accordingly, the movement of the power unit (20) is restricted, so that it can be fixed in the corresponding position.

[0346] The power fixing member (640) is coupled to the first bracket plate (621). Specifically, the power fixing member (640) is coupled through a fixing member connecting hole (624) formed through the first bracket plate (621).

[0347] The power fixing member (640) is coupled to the first bracket plate (621) so as to be movable in the direction toward and opposite to the coupling groove (323), and in the upward and downward directions in the illustrated embodiment. In addition, the power fixing member (640) can be maintained in a movable state. In one embodiment, the power fixing member (640) is formed in the form of a screw and can be screw-coupled to the first bracket plate (621).

[0348] The power fixing member (640) may be provided in any shape that can be accommodated in the joining groove (323) and pressurize the guide profile (320). In the illustrated embodiment, the power fixing member (640) includes a core member that extends in the vertical direction, penetrates the fixing member joining hole (624) and pressurizes the guide profile (320), and a handle member that is coupled to an upper end of the core member and is positioned on the upper side of the first bracket plate (621).

[0349] In the above embodiment, the operator can adjust the vertical position of the core member by rotating or applying pressure to the handle member.

[0350] A plurality of power fixing members (640) may be provided. The plurality of power fixing members (640) may be movably connected through at least one of the plurality of fixing member connecting holes (624). In the illustrated embodiment, a pair of power fixing members (640) are provided, and are connected through a pair of fixing member connecting holes (624) located on the right side of the front and the left side of the rear, respectively.

[0351] In any case, it is sufficient if the power fixing member (640) can be positioned vertically above the coupling groove (323).

[0352] A power stopper (650) is positioned between a pair of power fixing members (640).

[0353] The power stopper (650) is retractably received in the fixing hole (324). When the power stopper (650) is received in the fixing hole (324), the movement of the power unit (20) is restricted and can be fixed in that position.

[0354] The power stopper (650) is coupled to the first bracket plate (621). Specifically, the power stopper (650) is coupled through a stopper coupling hole (625) formed through the first bracket plate (621).

[0355] The power stopper (650) is coupled to the first bracket plate (621) so as to be movable in the direction toward the fixing hole (324) and in the direction opposite thereto, and in the illustrated embodiment, upward and downward. At this time, the power stopper (650) may be provided in a form in which it moves toward the fixing hole (324) without a separate external force, but an external force must be applied in order to move in the direction opposite to the fixing hole (324).

[0356] In one embodiment, the power stopper (650) may be configured to include an elastic member such as a spring. The elastic member may be configured to apply an elastic force to the power stopper (650) in a direction toward the guide profile (320).

[0357] Therefore, when the fixing hole (324) is not positioned vertically downward of the power stopper (650), the end portion in the extension direction of the power stopper (650) can be maintained in a state of contact by pressing against the surface of the profile body (321).

[0358] In addition, when the fixing hole (324) is positioned vertically below the power stopper (650), the power stopper (650) can be accommodated in the fixing hole (324) by the elastic force even if no separate external force is applied.

[0359] Accordingly, when the power unit (20) moves along the guide profile (320), the power stopper (650) is first received in the fixing hole (324) so ​​that the position where the power unit (20) should be fixed can be recognized. Then, when the power fixing member (640) is manipulated, the power unit (20) can be fixed at that position.

[0360] Accordingly, not only can the position of the power unit (20) be easily recognized, but the power unit (20) can also be stably maintained at a preset position.

[0361]

[0373] The first shaft member (710) is coupled with the moving power member (410). Specifically, the first shaft member (710) is coupled with a gear shaft (510) that penetrates the power member coupling hole (312).

[0374] The first axis member (710) is coupled to the second axis member (720).

[0378] The inner surface of the first shaft member (710) surrounding the gear shaft coupling portion (711) can be defined as an shaft identification surface (712).

[0379] The shaft identification surface (712) is in contact with the gear identification surface (520) of the gear shaft (510) accommodated in the gear shaft coupling portion (711). By the contact between the shaft identification surface (712) and the gear identification surface (520), a misalignment phenomenon between the gear shaft (510) and the first shaft member (710) can be prevented.

[0380] The shaft identification surface (712) is defined as the inner surface of the first shaft member (710) surrounding the gear shaft coupling portion (711). The shaft identification surface (712) is positioned corresponding to the position of the gear shaft coupling portion (711). In the illustrated embodiment, the shaft identification surface (712) is positioned adjacent to the other end in the extension direction of the first shaft member (710), i.e., the front end.

[0381] The axis identification surface (712) may be formed flat compared to the outer periphery of the first axis member (710). In one embodiment, the axis identification surface (712) may be formed as a plane extending in a horizontal or vertical direction.

[0382] A plurality of axis identification surfaces (712) may be formed. The plurality of axis identification surfaces (712) may be spaced apart from each other along the inner periphery of the first axis member (710). In the illustrated embodiment, a total of two pairs of axis identification surfaces (712) are provided. One pair of axis identification surfaces (712) is spaced apart from each other in the vertical direction. The other pair of axis identification surfaces (712) is spaced apart from each other in the left-right direction. Each pair of axis identification surfaces (712) is in contact with each of the plurality of axis identification surfaces (712).

[0383] The shape and arrangement of the shaft identification surface (712) can be changed according to the shape and arrangement of the gear identification surface (520).

[0384] The first axis member (710) is coupled with the second axis member (720) and rotates together.

[0385] The second shaft member (720) is another configuration of the shaft member (700), that is, the portion where the shaft member (700) is coupled with the circuit breaker (not shown) and the distribution frame (2).

[0389]

[0390] Referring to FIGS. 23 and 24, a state in which each component of the withdrawal device (1) according to an embodiment of the present invention is combined is illustrated as an example.

[0391] As illustrated in Fig. 23, the moving power member (410) is coupled with the gear shaft (510), and the gear shaft (510) is coupled with the first shaft member (710) of the shaft member (700). At this time, the first shaft member (710) is coupled with the second shaft member (720), and the second shaft member (720) is penetratedly coupled to the withdrawal device coupling portion (2d).

[0392] Accordingly, a circuit breaker (not shown) accommodated in the distribution frame (2) can be inserted or extracted by the power applied by the moving power member (410).

[0393] In addition, as illustrated in FIG. 24, the rotation power member (420) is coupled with the padlock guide (440). At this time, the rotation power member (420) and the padlock guide (440) are positioned between a pair of first plates (110) that are arranged to be offset to the right, and are supported by a power support bracket (150).

[0394] That is, the circuit breaker (not shown) accommodated in the distribution frame (2) and the padlock lever (2g) of the distribution frame (2) can be powered by different power sources, i.e., the moving power member (410) and the rotating power member (420), respectively.

[0395]

[0396] Referring to FIGS. 25 to 28, a process of coupling a lead-in / out device (1) according to an embodiment of the present invention with a distribution frame (2) is illustrated as an example. Through the above process, it will be understood that the lead-in / out device (1) is coupled not only with the distribution frame (2), but also with a circuit breaker (not shown) housed within the distribution frame (2).

[0397] Referring to Fig. 25, the draw-out device (1) is arranged parallel to the distribution frame (2). At this time, the draw-out device cover member (2e) provided on the distribution plate (2c) is rotated to open the draw-out device coupling portion (2d). The shaft member (700) of the draw-out device (1) is arranged parallel to the draw-out device coupling portion (2d). At this time, it will be understood that the shaft member (700) is arranged parallel to the direction in which the draw-out device (1) is coupled or separated from the distribution frame (2), that is, along the front-back direction in the illustrated embodiment.

[0398] Referring to Fig. 26, the shaft member (700) of the draw-out device (1) is first moved to the front side and is penetratedly connected to the draw-out device coupling portion (2d). At this time, it will be understood that the second shaft member (720) passes through an additional groove formed in the draw-out device coupling portion (2d) and is connected to the draw-out device coupling portion (2d).

[0399] By the above combination, the end portion in the extension direction of the second axis member (720), in the illustrated embodiment, the rear end portion, can be combined with a circuit breaker (not shown) accommodated in the distribution frame space (2b).

[0400] It will be understood that the above process is performed by separably connecting the handle portion (30) composed of the shaft member (700) to other components of the pull-out device (1), namely the bracket portion (10) and the power portion (20).

[0401] Referring to Fig. 27, the bracket part (10) is moved forward and coupled with the handle part (30), i.e., the handle part (30) coupled with the distribution plate (2c). At this time, the first shaft member (710) penetrates the key hole (313) of the power unit support part (300) and is supported by the coupling plate (311) and the coupling boss (314).

[0402] In addition, the padlock guide (440) is coupled with the padlock lever (2g). The space formed inside the padlock guide (440) accommodates the above-described part of the padlock lever (2g), that is, the part where the padlock lever (2g) penetrates the distribution plate (2c) and is coupled with the padlock (2h). The guide opening (441) formed on the outer periphery of the padlock guide (440) accommodates the above-described other part of the padlock lever (2g), that is, the part extending outward.

[0403] Furthermore, the magnet member (210) of the coupling member (200) is brought into contact with and coupled to the distribution plate (2c). At this time, it will be understood that the handle member (220) can be manipulated to adjust the coupling force between the magnet member (210) and the distribution plate (2c).

[0404] Accordingly, the bracket portion (10) can be coupled to a plurality of locations, i.e., the distribution plate (2c) and the handle portion (30), respectively. Accordingly, the coupling state of the bracket portion (10) and the insertion / withdrawal device (1) can be stably maintained.

[0405] Referring to Fig. 28, the power unit (20) is moved forward and coupled with the bracket unit (10) and the handle unit (30), respectively. The gear shaft (510) is accommodated in the gear shaft coupling unit (711). At this time, the gear shaft (510) is accommodated in the gear shaft coupling unit (711) so that the gear identification surface (520) and the shaft identification surface (712) are arranged parallel to each other and are in contact. Therefore, a misalignment phenomenon between the gear shaft (510) and the handle unit (30) can be prevented.

[0406] In addition, the power unit (20) is coupled with the bracket unit (10) so that the guide profile (320) is accommodated in the bracket accommodation space (623) of the power bracket (600). The guide profile (320) accommodated in the bracket accommodation space (623) supports the first bracket plate (621) of the coupling bracket (620) from the lower side. In addition, the second bracket plate (622) supports each side of the guide profile (320) in the width direction, i.e., the left and right sides.

[0407] At the same time, the guide rail (630) is slidably coupled to the guide groove (322). Accordingly, the power unit (20) can be moved in the direction in which it is coupled to the distribution frame (2), i.e., toward the front, while being prevented from swinging in the width direction or height direction.

[0408] Meanwhile, when the power unit (20) is moved forward to a preset position, the fixing hole (324) is positioned vertically below the power stopper (650). The power stopper (650), which was moving while pressing the upper surface of the profile body (321), is inserted into the fixing hole (324), thereby restricting further movement of the power unit (20).

[0409] In the above state, when the power fixing member (640) is manipulated and inserted into the joining groove (323) and the surface of the profile body (321) surrounding the lower side of the joining groove (323) is pressed, the power unit (20) can be fixed to a preset position.

[0410] Although not shown, it will be understood that the process illustrated in FIGS. 25 to 28 can be performed in reverse so that the lead-in / out device (1) can be separated from the distribution frame (2).

[0411]

[0412] Referring to Fig. 29, a state in which a drawer / withdrawal device (1) according to an embodiment of the present invention is completely coupled to a distribution frame (2) is illustrated as an example. In this state, a shaft member (700) penetrates the drawer / withdrawal device coupling portion (2d) and is coupled with a circuit breaker (not shown) accommodated in a distribution frame space (2b). In addition, a padlock guide (440) is coupled with a padlock lever (2g) located on the front side of a distribution plate (2c).

[0413] In the above state, when the rotation power member (420) is operated first and the padlock lever (2g) is rotated, the padlock (2h) can release the circuit breaker (not shown). Thereafter, when the movement power member (410) is operated second and the shaft member (700) is rotated, the circuit breaker (not shown) coupled thereto can be inserted or extracted.

[0414] After the insertion or withdrawal process of the circuit breaker (not shown) is completed, when the rotation power member (420) is operated again, the padlock lever (2g) and padlock (2h) can be rotated to lock the circuit breaker (not shown).

[0415] The withdrawal device (1) according to the embodiment of the present invention described above is configured such that the bracket portion (10), the power portion (20), and the handle portion (30) are each separable. Therefore, when the withdrawal device (1) is combined with the distribution frame (2), each component can be separated and sequentially combined with the distribution frame (2) and other components, thereby improving work convenience.

[0416] In addition, the power unit (20) and the bracket unit (10) are supported by a plurality of components and shaft members (700). Therefore, the coupling force between each component of the inlet / outlet device (1) and the coupling force with the distribution frame (2) can be increased.

[0417] Furthermore, the bracket portion (10) includes a guide groove (322), and the power portion (20) includes a guide rail (630) that is slidably coupled to the guide groove (322). By the coupling, the power portion (20) can be moved along the extension direction of the guide profile (320), but movement in other directions can be restricted.

[0418] Meanwhile, the power unit (20) includes a power fixing member (640) and a power stopper (650), and the bracket part (10) includes a coupling groove (323) and a fixing hole (324). The operator can move the power unit (20) to a preset position simply by moving the power stopper (650) until it is coupled to the fixing hole (324). In addition, the operator can maintain the power unit (20) at a preset position simply by manipulating the power fixing member (640) so that it is inserted into the coupling groove (323) and presses the guide profile (320).

[0419] In addition, the rotation power member (420) provided in the drawer (1) is coupled to the padlock lever (2g) by the padlock guide (440). Therefore, it will be understood that the drawer (1) can perform not only the drawer and drawer of the circuit breaker (not shown), but also the binding and release of the circuit breaker (not shown).

[0420] As a result, the process of combining and separating the inlet / outlet device (1) and the distribution frame (2) can be easily performed.
