[0002] A switch cabinet is an electrical device. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Its main function is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. In the known technical field, low-voltage switch cabinets are suitable for power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries for transmission, distribution and power conversion.

[0044] Embodiment 1:

[0045] On the one hand of the embodiment of this application, a pluggable adapter module 100 is provided, which includes an incoming line adapter module 101 and an outgoing line adapter module 102. The incoming line adapter module 101 and the outgoing line adapter module 102 are arranged side by side in the vertical direction on the sealing plate of the vertical busbar 210 of the switch cabinet; both the incoming line adapter module 101 and the outgoing line adapter module 102 include a contact assembly 110. The contact assembly 110 of the incoming line adapter module 101 is pluggably connected to the vertical busbar 210 of the switch cabinet, and the contact assembly 110 of the outgoing line adapter module 102 is pluggably connected to the outgoing copper busbar 220 of the switch cabinet; the contact assembly 110 includes a housing 111 and multiple groups of contact groups 112 arranged side by side in the housing 111. The contact group 112 includes one or more bridge-shaped contacts 1121. When there are multiple bridge-shaped contacts 1121, the multiple bridge-shaped contacts 1121 are stacked.

[0046] Specifically, as Figure 1 and Figure 2 shown, the pluggable adapter module 100 includes an incoming line adapter module 101 and an outgoing line adapter module 102. The incoming line adapter module 101 and the outgoing line adapter module 102 are arranged side by side in the vertical direction on the sealing plate of the vertical busbar 210 of the switch cabinet body, with the incoming line adapter module 101 arranged above the outgoing line adapter module 102 to form a "top incoming line, bottom outgoing line" structure.

[0047] The incoming line adapter module 101 and the outgoing line adapter module 102 include a contact assembly 110. One end of the contact assembly 110 of the incoming line adapter module 101 is pluggably connected to the vertical busbar 210 of the switch cabinet, and the other end is pluggably connected to the adapter copper busbar of the circuit breaker; one end of the contact assembly 110 of the outgoing line adapter module 102 is pluggably connected to the outgoing copper busbar 220, and the other end is pluggably connected to the adapter copper busbar of the circuit breaker.

[0048] Among them, as Figure 3 shown, the contact assembly 110 includes a housing 111. In a preferred solution of this application, the housing 111 includes a front housing 1111 and a rear housing 1112, as Figure 7 and Figure 8As shown, the front shell 1111 and the rear shell 1112 can be snap-connected through the bayonet 1113 and the convex rib 1114, so as to facilitate the replacement and adjustment of the number of bridge-type contacts 1121 inside the housing 111; the shape and structure of the front shell 1111 and the rear shell 1112 are both adapted to the shape and structure of the bridge-type contact 1121, and are provided with rectangular grooves, and a part of the bridge-type contact 1121 installed inside the housing 111 can be exposed through the rectangular grooves; three groups of contact groups 112 arranged side by side are provided inside the housing 111 to form a three-phase integrated structure. Each phase of the contact group 112 includes a preset number of bridge-type contacts 1121, and the number of bridge-type contacts 1121 can be one or more. During actual use, the specific number of bridge-type contacts 1121 can be selected according to the different specifications of the circuit breaker and the magnitude of the current. When the number of bridge-type contacts 1121 is multiple, the multiple bridge-type contacts 1121 are stacked.

[0049] It should be noted that both the incoming line transfer module 101 and the outgoing line transfer module 102 of the present application include a contact component 110. The contact component 110 includes a housing 111, and multiple groups of contact groups 112 are arranged side by side inside the housing 111 to make the unit heights of the multiple groups of contact groups 112 consistent; in a preferred solution of the present application, three groups of contact components 110 are provided inside the housing 111 to form a three-phase integrated structure. The existing incoming line transfer module and outgoing line transfer module are usually arranged on the left and right sides of the cabinet to form a "left incoming line, right outgoing line" structure. The unit heights of the bridge-type contacts corresponding to each phase in the transfer module are inconsistent. When it is necessary to switch between large current and small current, the modification is complicated due to the different heights, reducing the modification efficiency; while in the present application, multiple groups of contact groups 112 are arranged inside the same housing 111, making the unit heights of the individual contact groups 112 consistent, and the specific number of bridge-type contacts 1121 can be selected according to the different specifications of the circuit breaker and the magnitude of the current, improving the modification efficiency and convenience.

[0050] The pluggable adapter module 100 provided by this application includes an incoming line adapter module 101 and an outgoing line adapter module 102. The incoming line adapter module 101 and the outgoing line adapter module 102 are arranged side by side in the vertical direction on the sealing plate of the vertical busbar 210 of the switch cabinet to form a structure of incoming line from the top and outgoing line from the bottom. Such a structural arrangement can reduce the cabinet volume of the switch cabinet and improve the space utilization rate of the switch cabinet; both the incoming line adapter module 101 and the outgoing line adapter module 102 include a contact assembly 110. The contact assembly 110 of the incoming line adapter module 101 is pluggably connected to the vertical busbar 210 of the switch cabinet, and the contact assembly 110 of the outgoing line adapter module 102 is pluggably connected to the outgoing copper busbar 220 of the switch cabinet to form a good electrical circuit. The pluggable connection facilitates the replacement and maintenance of the incoming line adapter module 101 and the outgoing line adapter module 102; the contact assembly 110 includes a housing 111 and multiple groups of contact groups 112 arranged side by side in the housing 111. The contact group 112 includes one or more bridge-shaped contacts 1121. When there are multiple bridge-shaped contacts 1121, the multiple bridge-shaped contacts 1121 are stacked. The heights of the contact groups 112 are the same. The contact assembly 110 can increase or decrease the number of bridge-shaped contacts 1121 according to the actual current magnitude to achieve the switching between large current and small current, improving the restructuring efficiency and convenience. The pluggable adapter module 100 obtained by the above design has the incoming line adapter module 101 and the outgoing line adapter module 102 arranged on the same side of the switch cabinet. The arrangement of incoming line from the top and outgoing line from the bottom not only reduces the cabinet volume of the switch cabinet but also ensures that the heights of the bridge-shaped contacts 1121 corresponding to each phase in the contact assembly 110 in the cabinet are the same. When it is necessary to switch between large current and small current, only the number of bridge-shaped contacts 1121 needs to be selected according to the current magnitude, improving the restructuring efficiency.

[0051] In an implementable embodiment of this application, the pluggable adapter module 100 further includes an incoming line protective cover 120 and an outgoing line protective cover 130. The incoming line protective cover 120 is sleeved on the side of the incoming line adapter module 101 close to the vertical busbar 210, and the outgoing line protective cover 130 is sleeved on the side of the outgoing line adapter module 102 close to the outgoing copper busbar 220.

[0052] Specifically, the pluggable adapter module 100 further includes an incoming line protective cover 120 and an outgoing line protective cover 130. The incoming line protective cover 120 is sleeved on the side of the incoming line adapter module 101 close to the vertical busbar 210 to be located between the incoming line adapter module 101 and the vertical busbar 210, forming electrical isolation between the incoming line adapter module 101 and the vertical busbar 210; the outgoing line protective cover 130 is sleeved on the side of the outgoing line adapter module 102 close to the outgoing copper busbar 220 to be located between the outgoing line adapter module 102 and the outgoing copper busbar 220, forming electrical isolation between the outgoing line adapter module 102 and the outgoing copper busbar 220.

[0053] Furthermore, as Figure 6 shown, the surface of the incoming line protective cover 120 is provided with a plurality of protective holes 121; one end of the outgoing line protective cover 130 is further provided with an installation cavity 131 for inserting the outgoing line copper bar 220; the surface of the installation cavity 131 is provided with a first screw hole 1311 for screwing with the outgoing line copper bar 220.

[0054] Specifically, the incoming line protective cover 120 is used to sleeved on the side of the incoming line transfer module 101 close to the vertical bus bar 210 to achieve the effect of electrical insulation; to ensure that the contact assembly 110 of the incoming line transfer module 101 can be electrically connected to the vertical bus bar 210 by good plugging and unplugging, a plurality of protective holes 121 are opened on the side of the incoming line protective cover 120 close to the vertical bus bar 210, and the opening positions and sizes of the protective holes 121 are adapted to the number and sizes of the bridge-shaped contacts 1121 of the contact assembly 110; when the incoming line transfer module 101 is installed in the incoming line protective cover 120, the contact assembly 110 of the incoming line transfer module 101 can be plugged and unplugged with the vertical bus bar 210 through the protective holes 121.

[0055] As Figure 5 shown, the outgoing line protective cover 130 is used to sleeved on the side of the outgoing line transfer module 102 close to the outgoing line copper bar 220 to achieve the effect of electrical insulation; to ensure that the contact assembly 110 of the outgoing line transfer module 102 can be electrically connected to the outgoing line copper bar 220 by good plugging and unplugging, an installation cavity 131 is opened on the side of the outgoing line protective cover 130 close to the outgoing line copper bar 220, and when the outgoing line transfer module 102 is installed in the outgoing line protective cover 130, the installation cavity 131 communicates with the outgoing line transfer module 102; the installation cavity 131 is used to install the outgoing line copper bar 220, so that when the outgoing line transfer module 102 is installed in the outgoing line protective cover 130, the contact assembly 110 of the outgoing line transfer module 102 can be plugged and unplugged with the outgoing line copper bar 220. Among them, a first screw hole 1311 is opened on the surface of the installation cavity 131, and correspondingly, one end of the outgoing line copper bar 220 is also provided with a screw hole. When the outgoing line copper bar 220 is inserted into the installation cavity 131, the outgoing line copper bar 220 can be fixedly connected to the outgoing line protective cover 130 through the cooperation of the fixing member and the first screw hole 1311, improving the stability and reliability of the plugging and unplugging connection between the outgoing line transfer module 102 and the outgoing line copper bar 220.

[0056] In the prior art, when it is necessary to remove the incoming line adapter module or the outgoing line adapter module for maintenance or replacement, the vertical busbar will be directly exposed after the cover of the switch cabinet is removed, so it is necessary to shut down the power supply, which reduces the operating efficiency, takes a long time, and increases the operation and maintenance costs. However, the present application, through the provision of the incoming line protective cover 120 and the outgoing line protective cover 130, ensures that the incoming line adapter module 101 and the outgoing line adapter module 102 are respectively connected to the vertical busbar 210 and the outgoing copper busbar 220 in a stable and pluggable manner, and also provides good electrical insulation. When it is necessary to remove the incoming line adapter module 101 or the outgoing line adapter module 102, the vertical busbar 210 is isolated by the incoming line protective cover 120 and will not be exposed, and no power-off operation is required, which improves the operating efficiency and reduces the operation and maintenance costs.

[0057] In one achievable implementation of the present application, as Figure 4 As shown, the pluggable adapter module 100 also includes a locking member 150 arranged in the shell 111 of the contact assembly 110; the surface of the shell 111 is provided with at least one first limiting hole 113, and the incoming line protection cover 120 and the outgoing line protection cover 130 are correspondingly provided with at least one second limiting hole 140, and the first limiting hole 113 is coaxially arranged with the second limiting hole 140 and has corresponding positions; the limiting ends of the locking member 150 are successively penetrated through the first limiting hole 113 and the second limiting hole 140 to clamp the contact assembly 110 with the incoming line protection cover 120 or the outgoing line protection cover 130.

[0058] Specifically, the pluggable adapter module 100 also includes a locking member 150, which is arranged inside the shell 111 of the contact assembly 110; the surface of the shell 111 is provided with at least one first limiting hole 113, and correspondingly, the incoming line protection cover 120 and the outgoing line protection cover 130 are also correspondingly provided with at least one second limiting hole 140. In a preferred embodiment of the present application, two locking members 150 are provided in the shell 111 of the contact assembly 110, and a locking member 150 is provided between each two groups of contact groups 112; each locking member 150 is correspondingly provided with two first limiting holes 113, and the two first limiting holes 113 are respectively provided on the upper and lower sides of the locking member 150 along the stacking direction of the bridge-type contacts 1121 in the shell 111; similarly, the incoming line protection cover 120 and the outgoing line protection cover 130 are also provided at each locking member. Two second limiting holes 140 are arranged at the position corresponding to the member 150, and the two second limiting holes 140 correspond to the position of the first limiting hole 113 and are coaxially arranged, so that the limiting end of each locking member 150 can be sequentially passed through the first limiting hole 113 of the shell 111 of the contact assembly 110 and the second limiting hole 140 of the incoming line protection cover 120 or the outgoing line protection cover 130, so that the contact assembly 110 is snap-connected with the incoming line protection cover 120 or the outgoing line protection cover 130 through the locking member 150.

[0059] By setting the locking member 150, the contact assembly 110 can be installed on the outlet protection cover 130 or the incoming protection cover 120 and can be more stable by snapping into the first limiting hole 113 and the second limiting hole 140 in sequence, further improving the stability and reliability of the pluggable adapter module 100.

[0060] Furthermore, if Figure 4 , Figure 9 and Figure 10 As shown, the locking member 150 includes an elastic sheet 151 and a rotating shaft 152 passing through the middle of the elastic sheet 151, the elastic sheet 151 is located in the shell 111 of the contact assembly 110, and the ends of the elastic sheet 151 are sequentially clamped in the first limiting hole 113 of the shell 111 and the second limiting hole 140 of the incoming line protection cover 120 or the outgoing line protection cover 130; rotating the rotating shaft 152 can drive the elastic sheet 151 to rotate and make its end pressed in the shell 111 or protruding outside the first limiting hole 113 of the shell 111, so that the contact assembly 110 and the incoming line protection cover 120 or the outgoing line protection cover 130 are unlocked or locked.

[0061] Specifically, the locking member 150 includes an elastic sheet 151 and a rotating shaft 152. The rotating shaft 152 is inserted into the middle of the elastic sheet 151 to be connected with the elastic sheet 151 to form an integrated structure. The elastic sheet 151 is arranged in the housing 111 and its ends are sequentially clamped in the first limiting hole 113 of the housing 111 and the second limiting hole 140 of the incoming line protection cover 120 or the outgoing line protection cover 130. Since the elastic sheet 151 has elastic potential energy, the portion protruding from the first limiting hole 113 and the second limiting hole 140 can be pressed into the housing 111 and store energy under the rotation and pressure of the rotating shaft 152, and can also release energy and restore to a position state where the portion protrudes from the first limiting hole 113 and the second limiting hole 140 again.

[0062] When the rotating shaft 152 is rotated counterclockwise, the elastic sheet 151 can be driven to rotate, so that the end of the elastic sheet 151 that is clamped in the first limiting hole 113 and the second limiting hole 140 follows the rotation and is pressed into the shell 111. At this time, the end of the elastic sheet 151 is no longer clamped in the first limiting hole 113 and the second limiting hole 140, and the contact assembly 110 is unlocked from the incoming line protection cover 120 or the outgoing line protection cover 130, so that the contact assembly 110 can be removed from the incoming line protection cover 120 or the outgoing line protection cover 130.

[0063] When the rotary shaft 152 is rotated clockwise, the elastic piece 151 releases energy and returns to the position state where the parts sequentially protrude from the first limiting hole 113 and the second limiting hole 140 again. As a result, the end of the elastic piece 151 is clamped in the first limiting hole 113 and the second limiting hole 140 again and protrudes from the housing 111. At this time, the end of the elastic piece 151 is clamped with the first limiting hole 113 and the second limiting hole 140 again, and the contact component 110 is locked with the incoming line protective cover 120 or the outgoing line protective cover 130, so that the contact component 110 can be installed with the incoming line protective cover 120 or the outgoing line protective cover 130.

[0064] Through the cooperation of the rotary shaft 152 and the elastic piece 151, the contact component 110 can be installed or removed from the incoming line protective cover 120 or the outgoing line protective cover 130 according to actual needs, making the disassembly and assembly process more flexible and convenient.

[0065] Furthermore, the elastic piece 151 includes a body 1511 and a buckle end 1512 provided at the end of the body 1511; a circular hole is formed in the body 1511 for passing through the rotary shaft 152; the buckle end 1512 is inclined relative to the body 1511 to be clamped with the first limiting hole 113 of the housing 111.

[0066] Specifically, as Figure 10 shown, the elastic piece 151 includes a body 1511. The body 1511 is in a strip-shaped thin sheet structure. A circular hole is formed in the middle of the body 1511 for passing through the rotary shaft 152; buckle ends 1512 are provided at opposite ends of the body 1511. The buckle ends 1512 are used to protrude from the first limiting hole 113 and the second limiting hole 140 and are buckled and connected with the first limiting hole 113 and the second limiting hole 140; the buckle ends 1512 are inclined relative to the body 1511 to be more stably buckled and connected with the first limiting hole 113 and the second limiting hole 140, further improving the stability and reliability of the connection of the pluggable adapter module 100.

[0067] In a preferred solution of the present application, a guiding piece 1513 is further provided on one side of the body 1511. A torsion part 153 is also connected to the end of the rotary shaft 152 far from the elastic piece 151. The end of the torsion part 153 far from the elastic piece 151 protrudes from the mounting hole 1115 of the housing 111; a spiral surface 1531 is provided on the side of the torsion part 153 close to the elastic piece 151, and the guiding piece 1513 abuts against the spiral surface 1531.

[0068] Specifically, as Figure 10 shown, a guiding piece 1513 also protrudes from one side of the body 1511. Correspondingly, as Figure 9As shown, one end of the rotating shaft 152 away from the elastic sheet 151 is also connected to the torsion portion 153; a mounting hole 1115 is provided on the shell 111, the rotating shaft 152 is penetrated into the mounting hole 1115, and the end of the torsion portion 153 is penetrated into the mounting hole 1115 opened on the shell 111 and protrudes from the surface of the shell 111, so that the operator can twist the locking member 150 more easily; a spiral surface 1531 is provided on the side of the torsion portion 153 close to the elastic sheet 151, and the guide sheet 1513 is in contact with the spiral surface 1531, so that the torsion portion 153 slides along the guide sheet 1513 during rotation.

[0069] It should be noted that in a preferred embodiment of the present application, the torsion portion 153 protrudes from the surface of the shell 111 and an arrow mark can also be set to indicate its rotation direction; correspondingly, an arrow mark can also be set on the outer surface of the shell 111 to indicate the rotation direction of the locking member 150 for unlocking and locking. The present application does not impose any restrictions on the specific setting method and setting position of the arrow mark.

[0070] Furthermore, if Figure 9 As shown, a protrusion 1532 is also provided on the side wall of the torsion portion 153, and a limiting wall 114 is also provided on one side of the inner wall of the shell 111 close to the torsion portion 153. The limiting wall 114 is semi-enclosed on the circumference of the torsion portion 153. When the torsion portion 153 drives the rotating shaft 152 to rotate, the two side ends of the limiting wall 114 can limit the protrusion 1532 to limit the rotation range of the torsion portion 153.

[0071] Specifically, a protrusion 1532 is further provided on the side wall of the torsion portion 153, and correspondingly, a limiting wall 114 is further provided on one side of the inner wall of the shell 111 close to the torsion portion 153. The limiting wall 114 is semi-enclosed on the circumference of the torsion portion 153 and corresponds to the position of the protrusion 1532; when the torsion portion 153 drives the rotating shaft 152 to rotate clockwise or counterclockwise, the protrusion 1532 can rotate with the torsion portion 153 until it is limited by the left end portion or the right end portion of the limiting wall 114 and cannot rotate, thereby limiting the rotation range of the torsion portion 153, so that the torsion portion 153 can only drive the locking member 150 to rotate within the range of unlocking and locking.

[0072] In a preferred embodiment of the present application, the pluggable adapter module 100 also includes a mounting plate 160, which is provided with a through groove for installing the incoming line protection cover 120 and the outgoing line protection cover 130; the incoming line protection cover 120 and the outgoing line protection cover 130 are respectively installed in the through groove and screwed to the mounting plate 160; the periphery of the mounting plate 160 is provided with a second screw hole 161, and the second screw hole 161 is penetrated by a fixing piece to screw the mounting plate 160 to the cabinet sheet metal of the switch cabinet.

[0073] Specifically, the pluggable adapter module 100 further includes a mounting plate 160. Corresponding through slots for mounting the incoming line protective cover 120 and the outgoing line protective cover 130 are provided on the mounting plate 160. The size of the through slots is adapted to the sizes of the incoming line protective cover 120 and the outgoing line protective cover 130. Threaded holes are provided at the edges of both the incoming line protective cover 120 and the outgoing line protective cover 130. Correspondingly, threaded holes are also formed on the mounting plate 160, so that the incoming line protective cover 120 and the outgoing line protective cover 130 respectively pass through the fixing members and are fixedly connected to the mounting plate 160. A plurality of second screw holes 161 are provided on the periphery of the mounting plate 160. The second screw holes 161 are used to pass through the fixing members, so that the mounting plate 160 is fixedly connected to the cabinet body sheet metal of the switch cabinet. Through the arrangement of the mounting plate 160, support and protection are provided for the incoming line protective cover 120 and the outgoing line protective cover 130, making the connection of the pluggable adapter module 100 more stable and reliable.

[0074] Embodiment 2:

[0075] On the one hand of the embodiment of the present application, a pluggable adapter module 100 is provided, which includes an incoming line adapter module 101 and an outgoing line adapter module 102. The incoming line adapter module 101 and the outgoing line adapter module 102 are arranged side by side in the vertical direction on the sealing plate of the vertical busbar 210 of the switch cabinet. Both the incoming line adapter module 101 and the outgoing line adapter module 102 include a contact assembly 110. The contact assembly 110 of the incoming line adapter module 101 is pluggably connected to the vertical busbar 210 of the switch cabinet, and the contact assembly 110 of the outgoing line adapter module 102 is pluggably connected to the outgoing line copper busbar 220 of the switch cabinet. The contact assembly 110 includes a housing 111 and multiple groups of contact groups 112 arranged side by side in the housing 111. Each contact group 112 includes one or more bridge-shaped contacts 1121. When there are multiple bridge-shaped contacts 1121, the multiple bridge-shaped contacts 1121 are stacked.

[0076] Specifically, as Figure 1 and Figure 2 shown, the pluggable adapter module 100 includes an incoming line adapter module 101 and an outgoing line adapter module 102. The incoming line adapter module 101 and the outgoing line adapter module 102 are arranged side by side in the vertical direction on the sealing plate of the vertical busbar 210 of the switch cabinet body, with the incoming line adapter module 101 arranged above the outgoing line adapter module 102 to form a structure of "upper incoming line and lower outgoing line".

[0077] The incoming line adapter module 101 and the outgoing line adapter module 102 include a contact assembly 110. One end of the contact assembly 110 of the incoming line adapter module 101 is pluggably connected to the vertical busbar 210 of the switch cabinet, and the other end is pluggably connected to the adapter copper busbar of the circuit breaker. One end of the contact assembly 110 of the outgoing line adapter module 102 is pluggably connected to the outgoing line copper busbar 220, and the other end is pluggably connected to the adapter copper busbar of the circuit breaker.

[0078] Among them, as Figure 3 shown, the contact component 110 includes a housing 111. In a preferred solution of the present application, the housing 111 includes a front housing 1111 and a rear housing 1112. As Figure 7 and Figure 8 shown, the front housing 1111 and the rear housing 1112 can be snap-connected through a bayonet 1113 and a rib 1114, so as to facilitate the replacement and adjustment of the number of bridge contacts 1121 inside the housing 111; the shape structures of the front housing 1111 and the rear housing 1112 are both adapted to the shape structure of the bridge contact 1121, and are provided with rectangular grooves, and a part of the bridge contact 1121 installed in the housing 111 can be exposed from the rectangular grooves; three groups of contact groups 112 arranged side by side are provided inside the housing 111 to form a three-phase integrated structure. Each phase contact group 112 includes a preset number of bridge contacts 1121, and the number of bridge contacts 1121 can be one or more. In the actual use process, the specific number of bridge contacts 1121 can be selected according to the different specifications of the circuit breaker and the magnitude of the current. When the number of bridge contacts 1121 is multiple, the multiple bridge contacts 1121 are stacked.

[0079] It should be noted that both the incoming line transfer module 101 and the outgoing line transfer module 102 of the present application include a contact component 110. The contact component 110 includes a housing 111, and multiple groups of contact groups 112 are arranged side by side inside the housing 111 to make the unit heights of the multiple groups of contact groups 112 consistent; in a preferred solution of the present application, three contact components 110 are provided inside the housing 111 to form a three-phase integrated structure. The existing incoming line transfer module and outgoing line transfer module are usually arranged on the left and right sides of the cabinet to form a "left incoming line, right outgoing line" structure. The unit heights of the bridge contacts corresponding to each phase in the transfer module are inconsistent. When switching between large current and small current is required, the modification is complicated due to the different heights, reducing the modification efficiency; while in the present application, multiple groups of contact groups 112 are arranged in the same housing 111, making the unit heights of the contact groups 112 consistent, and the specific number of bridge contacts 1121 can be selected according to the different specifications of the circuit breaker and the magnitude of the current, improving the modification efficiency and convenience.

[0080] The pluggable adapter module 100 provided by this application includes an incoming line adapter module 101 and an outgoing line adapter module 102. The incoming line adapter module 101 and the outgoing line adapter module 102 are arranged side by side in the vertical direction on the sealing plate of the vertical busbar 210 of the switchgear to form a structure of incoming line from the top and outgoing line from the bottom. Such a structural arrangement can reduce the cabinet volume of the switchgear and improve the space utilization rate of the switchgear; both the incoming line adapter module 101 and the outgoing line adapter module 102 include a contact assembly 110. The contact assembly 110 of the incoming line adapter module 101 is pluggably connected to the vertical busbar 210 of the switchgear, and the contact assembly 110 of the outgoing line adapter module 102 is pluggably connected to the outgoing copper busbar 220 of the switchgear to form a good electrical circuit. The pluggable connection facilitates the replacement and maintenance of the incoming line adapter module 101 and the outgoing line adapter module 102; the contact assembly 110 includes a housing 111 and multiple groups of contact groups 112 arranged side by side in the housing 111. The contact group 112 includes one or more bridge-shaped contacts 1121. When there are multiple bridge-shaped contacts 1121, the multiple bridge-shaped contacts 1121 are stacked. The height of the contact group 112 is consistent. The contact assembly 110 can increase or decrease the number of bridge-shaped contacts 1121 according to the actual current magnitude to achieve the switching between large current and small current, improving the restructuring efficiency and convenience. The pluggable adapter module 100 obtained by the above design arranges the incoming line adapter module 101 and the outgoing line adapter module 102 on the same side of the switchgear. The setting method of incoming line from the top and outgoing line from the bottom not only reduces the cabinet volume of the switchgear but also ensures that the heights of the bridge-shaped contacts 1121 corresponding to each phase in the contact assembly 110 in the cabinet are consistent. When it is necessary to switch between large current and small current, only the number of bridge-shaped contacts 1121 needs to be selected according to the current magnitude, improving the restructuring efficiency.

[0081] In an implementable embodiment of this application, the pluggable adapter module 100 further includes an incoming line protective cover 120 and an outgoing line protective cover 130. The incoming line protective cover 120 is sleeved on the side of the incoming line adapter module 101 close to the vertical busbar 210, and the outgoing line protective cover 130 is sleeved on the side of the outgoing line adapter module 102 close to the outgoing copper busbar 220.

[0082] Specifically, the pluggable adapter module 100 further includes an incoming line protective cover 120 and an outgoing line protective cover 130. The incoming line protective cover 120 is sleeved on the side of the incoming line adapter module 101 close to the vertical busbar 210 to be located between the incoming line adapter module 101 and the vertical busbar 210, forming electrical isolation between the incoming line adapter module 101 and the vertical busbar; the outgoing line protective cover 130 is sleeved on the side of the outgoing line adapter module 102 close to the outgoing copper busbar 220 to be located between the outgoing line adapter module 102 and the outgoing copper busbar 220, forming electrical isolation between the outgoing line adapter module 102 and the outgoing copper busbar 220.

[0083] Further, asFigure 6 As shown, a plurality of protection holes 121 are provided on the surface of the incoming line protection cover 120; an installation cavity 131 is further provided at one end of the outgoing line protection cover 130, and the installation cavity 131 is used for inserting the outgoing line copper busbar 220; a first screw hole 1311 is provided on the surface of the installation cavity 131, and the first screw hole 1311 is used for screwing connection with the outgoing line copper busbar 220.

[0084] Specifically, the incoming line protection cover 120 is used for sleeving on one side of the incoming line transfer module 101 close to the vertical busbar 210 to achieve the effect of electrical insulation; to ensure that the contact assembly 110 of the incoming line transfer module 101 can be well plugged and unplugged and electrically connected to the vertical busbar 210, a plurality of protection holes 121 are provided on one side of the incoming line protection cover 120 close to the vertical busbar 210, and the opening positions and sizes of the protection holes 121 are adapted to the number and sizes of the bridge-shaped contacts 1121 of the contact assembly 110; when the incoming line transfer module 101 is installed in the incoming line protection cover 120, the contact assembly 110 of the incoming line transfer module 101 can be plugged and unplugged and connected to the vertical busbar 210 through the protection holes 121.

[0085] As Figure 5 shown, the outgoing line protection cover 130 is used for sleeving on one side of the outgoing line transfer module 102 close to the outgoing line copper busbar 220 to achieve the effect of electrical insulation; to ensure that the contact assembly 110 of the outgoing line transfer module 102 can be well plugged and unplugged and electrically connected to the outgoing line copper busbar 220, an installation cavity 131 is provided on one side of the outgoing line protection cover 130 close to the outgoing line copper busbar 220. When the outgoing line transfer module 102 is installed in the outgoing line protection cover 130, the installation cavity 131 communicates with the outgoing line transfer module 102; the installation cavity 131 is used for installing the outgoing line copper busbar 220, so that when the outgoing line transfer module 102 is installed in the outgoing line protection cover 130, the contact assembly 110 of the outgoing line transfer module 102 can be plugged and unplugged and connected to the outgoing line copper busbar 220. Among them, a first screw hole 1311 is provided on the surface of the installation cavity 131. Correspondingly, a screw hole is also provided at one end of the outgoing line copper busbar 220. When the outgoing line copper busbar 220 is inserted into the installation cavity 131, the outgoing line copper busbar 220 can be fixedly connected to the outgoing line protection cover 130 through the cooperation of a fixing member and the first screw hole 1311, improving the stability and reliability of the plugging and unplugging connection between the outgoing line transfer module 102 and the outgoing line copper busbar 220.

[0086] In the prior art, when it is necessary to remove the incoming line transfer module or the outgoing line transfer module for maintenance or replacement, since the vertical busbar will be directly exposed after removing the sealing plate of the switch cabinet, power-off operation is required, which reduces the operation efficiency, takes a long time, and increases the operation and maintenance costs. However, through the settings of the incoming line protective cover 120 and the outgoing line protective cover 130 in this application, while ensuring the stable pluggable connection between the incoming line transfer module 101, the outgoing line transfer module 102 and the vertical busbar 210, the outgoing line copper busbar 220 respectively, good electrical insulation is also provided. When it is necessary to remove the incoming line transfer module 101 or the outgoing line transfer module 102, the vertical busbar 210 is isolated by the incoming line protective cover 120 and will not be exposed, so power-off operation is not required, the operation efficiency is improved, and the operation and maintenance costs are reduced.

[0087] In an implementable embodiment of the present application, as Figure 11 shown, the locking member 150 includes a retaining piece 154 and a rotating shaft 152 disposed on one side of the retaining piece 154; the retaining piece 154 is located inside the housing 111 of the contact assembly 110, and one end of the retaining piece 154 is sequentially clamped in the first limiting hole 113 of the housing 111 and the second limiting hole 140 of the incoming line protective cover 120 or the outgoing line protective cover 130; by rotating the rotating shaft 152, the retaining piece 154 can be made to abut against or separate from the protruding portion 1521 on the rotating shaft 152, thereby driving one end of the retaining piece 154 to protrude outside the first limiting hole 113 of the housing 111 or be pressed inside the housing 111, so that the contact assembly 110 is locked or unlocked with the incoming line protective cover 120 or the outgoing line protective cover 130.

[0088] Specifically, the locking member 150 includes a retaining piece 154 and a rotating shaft 152. The retaining piece 154 is located inside the housing 111 of the contact assembly 110, and one end of the retaining piece 154 can be sequentially clamped in the first limiting hole 113 of the housing 111 and the second limiting hole 140 of the incoming line protective cover 120 or the outgoing line protective cover 130; as Figure 14 shown, the rotating shaft 152 is located on the side of the retaining piece 154 away from the first limiting hole 113 and the second limiting hole 140. A protruding portion 1521 is provided on the shaft arm of the rotating shaft 152. During the rotation of the rotating shaft 152, the protruding portion 1521 can abut against or separate from the retaining piece 154.

[0089] When the rotating shaft 152 is rotated counterclockwise, the protruding portion 1521 on the shaft arm of the rotating shaft 152 can be separated from the retaining piece 154. At this time, one end of the retaining piece 154 disposed in the first limiting hole 113 of the housing 111 is driven to be pressed inside the housing 111, and one end of the retaining piece 154 is no longer clamped with the first limiting hole 113 and the second limiting hole 140. The contact assembly 110 is unlocked with the incoming line protective cover 120 or the outgoing line protective cover 130, so that the contact assembly 110 can be removed from the incoming line protective cover 120 or the outgoing line protective cover 130.

[0090] When the rotating shaft 152 is rotated clockwise, the protrusion 1521 on the shaft arm of the rotating shaft 152 can be brought into contact with the baffle 154. At this time, one end of the baffle 154 disposed in the first limiting hole 113 of the housing 111 is driven to protrude into the first limiting hole 113 and the second limiting hole 140 and is locked, and the contact assembly 110 is locked with the incoming line protective cover 120 or the outgoing line protective cover 130, so that the contact assembly 110 can be installed with the incoming line protective cover 120 or the outgoing line protective cover 130. Through the cooperation of the rotating shaft 152 and the baffle 154, the contact assembly 110 can be installed or removed from the incoming line protective cover 120 or the outgoing line protective cover 130 according to actual needs, making the disassembly and assembly process more flexible and convenient.

[0091] Further, one end of the rotating shaft 152 is also connected with a torsion portion 153, and the end of the torsion portion 153 protrudes from the housing 111; a convex block 1532 is also provided on the side wall of the torsion portion 153. As Figure 13 shown, a limiting wall 114 is also provided on one side of the inner wall of the housing 111 close to the torsion portion 153. The limiting wall 114 is semi-surrounded on the periphery of the torsion portion 153. When the torsion portion 153 drives the rotating shaft 152 to rotate, the two end portions of the limiting wall 114 can limit the convex block 1532 to limit the rotation range of the torsion portion 153.

[0092] Specifically, as Figure 14 shown, one end of the rotating shaft 152 is also connected with a torsion portion 153; an installation hole 1115 is provided on the housing 111. The rotating shaft 152 is passed through the installation hole 1115 and the end of the torsion portion 153 is passed through the installation hole 1115 opened on the housing 111 and protrudes from the surface of the housing 111, so that the operator can twist the locking member 150 more easily.

[0093] It should be noted that in a preferred solution of the present application, an arrow mark may be provided on the surface of the housing 111 where the torsion portion 153 protrudes to indicate its rotation direction; correspondingly, an arrow mark may also be provided on the outer surface of the housing 111 to indicate the rotation direction of the locking member 150 for unlocking and locking. The present application does not impose any restrictions on the specific setting method and setting position of the arrow mark.

[0094] The side wall of the torsion part 153 is further provided with a convex block 1532. Correspondingly, a limiting wall 114 is further provided on the inner wall of the housing 111 close to the torsion part 153. The limiting wall 114 is semi-surroundingly arranged on the periphery of the torsion part 153 and corresponds to the position of the convex block 1532. When the torsion part 153 drives the rotating shaft 152 to rotate clockwise or counterclockwise, the convex block 1532 can follow the torsion part 153 to rotate until it is limited by the left end or the right end of the limiting wall 114 and cannot rotate, so as to limit the rotation range of the torsion part 153, and the torsion part 153 can only drive the locking part 150 to rotate within the unlocking and locking ranges.

[0095] Furthermore, the locking part 150 further includes a compression spring 155 and a torsion spring 156. The retaining piece 154 includes a first retaining piece 1541, a second retaining piece 1542 and a third retaining piece 1543 which are arranged in parallel in sequence. The ends of the first retaining piece 1541, the second retaining piece 1542 and the third retaining piece 1543 are connected. The second retaining piece 1542 is used for being clamped in the first limiting hole 113 of the housing 111 and the second limiting hole 140 of the incoming line protection cover 120 or the outgoing line protection cover 130. The compression spring 155 is sleeved on the outer periphery of the second retaining piece 1542 and is located between the first retaining piece 1541 and the third retaining piece 1543. The torsion spring 156 includes a torsion spring part 1561, a first extension part 1562 and a second extension part 1563 which are integrally connected. Correspondingly, an installation hole 1115 for passing through the rotating shaft 152 is formed in the housing 111. A torsion spring groove 1116 for installing the torsion spring part 1561 is provided on the periphery of the installation hole 1115. The end of the rotating shaft 152 abuts against the torsion spring part 1561. A clamping groove 1117 for clamping the first extension part 1562 and the second extension part 1563 is extended on the periphery of the torsion spring groove 1116.

[0096] Specifically, the locking part 150 further includes a compression spring 155. As Figure 15As shown, the retaining piece 154 is in the shape of a "mountain", which includes a first retaining piece 1541, a second retaining piece 1542, and a third retaining piece 1543 arranged in parallel from left to right in sequence. The length of the second retaining piece 1542 is longer than that of the first retaining piece 1541 and the third retaining piece 1543, so that the second retaining piece 1542 can protrude to the first limiting hole 113 and the second limiting hole 140. One sides of the first retaining piece 1541, the second retaining piece 1542, and the third retaining piece 1543 away from the first limiting hole 113 and the second limiting hole 140 are connected as a whole, so that the whole retaining piece 154 can better abut against the rotating shaft 152. The compression spring 155 is sleeved on the outer periphery of the second retaining piece 1542 and is located between the first retaining piece 1541 and the third retaining piece 1543. There are gaps between the first retaining piece 1541 and the second retaining piece 1542, and between the third retaining piece 1543 and the second retaining piece 1542. The compression spring 155 can be placed in the gaps to be sleeved on the outer periphery of the second retaining piece 1542. When the retaining piece 154 is separated from the convex portion 1521 of the rotating shaft 152, the second retaining piece 1542 is driven and pressed into the housing 111. At this time, the compression spring 155 releases energy. When the rotating shaft 152 rotates to make the convex portion 1521 abut against the retaining piece 154, the compression spring 155 is compressed and stores energy to make the retaining piece 154 return to the position state where it partially protrudes from the first limiting hole 113 and the second limiting hole 140 again. Through the setting of the compression spring 155, the unlocking and locking processes of the locking member 150 can be made more efficient and reliable.

[0097] As Figure 16 shown, the locking member 150 further includes a torsion spring 156. The torsion spring 156 includes a torsion spring portion 1561, a first extension portion 1562, and a second extension portion 1563 that are integrally connected. As Figure 12 shown, correspondingly, a torsion spring groove 1116 is provided on the periphery of the mounting hole 1115 for passing through the rotating shaft on the housing 111. The torsion spring groove 1116 is used for installing the torsion spring portion 1561. A clamping groove 1117 adapted to the structural dimensions of the first extension portion 1562 and the second extension portion 1563 extends from the periphery of the torsion spring groove 1116 to be used for clamping the first extension portion 1562 and the second extension portion 1563, so that the connection between the torsion spring 156 and the housing 111 is more stable. A flange 1522 is provided at one end of the rotating shaft 152 away from the torsion portion 153. When the rotating shaft 152 is passed through the housing 111, the flange 1522 at the end of the rotating shaft 152 abuts against the torsion spring 156. When the rotating shaft 152 rotates, the torsion spring 156 can cooperate with the rotating shaft 152, so that the rotation process of the rotating shaft 152 is more stable and reliable.
