Description

Technical Field

[0001] The invention relates to the technical field of switch cabinets, in particular to a unit main circuit static plug-in unit, a power distributor and a multi-circuit unit assembly. Background Art

[0002] At present, in the 1 / 2 unit assembly, the 125A / 3-phase (unit main circuit rated current) power distributor uses copper busbar routing to support the setting of auxiliary circuit connectors with 24 wiring points, and the unit module is 200mm. The 63A / 3-phase power distributor uses wire routing to support the setting of auxiliary circuit connectors with 32 wiring points, and the unit module is 200mm or 150mm.

[0003] The power distributor of the 1 / 4 unit adopts wire routing, the rated current of the unit main circuit is 32A, and the unit module is 200mm.

[0004] According to the market user equipment requirements, the 1 / 4 unit can only be used in terminal applications and cannot solve the installation space requirements of control circuit devices. In contrast, the 1 / 2 unit can effectively solve this problem. However, although the 1 / 2 unit with a unit module of 150mm can achieve 12 layers and 24 circuits in a switch cabinet device, the user requires a single device to have 36 circuits for a 5kVA motor control circuit, which is beyond the capacity of the 1 / 2 and 1 / 4 units. At the same time, the user also requires the unit main circuit rated current to be at least 63A (the actual operating current of the unit is 40A in actual application) and support the setting of auxiliary circuit connectors with 20 wiring points.

[0005] Only 1 / 3 unit with unit module of 150mm can realize 12 layers and 36 circuits of a switch cabinet equipment.

[0006] In the prior art, the 1 / 3 unit has basically no customer applications and very few products. The inner width of the 1 / 3 unit is only 155mm. There are limitations on the structural dimensions of the unit main circuit connectors and the electrical clearance when arranging the unit main circuit connectors. The existing unit main circuit dynamic plug-ins and unit main circuit static plug-ins have large structural dimensions, making it difficult to route wires in the power distributor, and the unit module can only be 200mm. Summary of the invention

[0007] The technical problem to be solved by the present invention is that the static plug-in unit main circuit on the existing power distributor occupies a large space and cannot be adapted to units with smaller inner width and smaller unit module, such as 1 / 3 unit with a unit module of 150mm.

[0077] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The present application can be embodied by many different forms of embodiments, and the protection scope of the present application is not limited to the embodiments mentioned in the text. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work should belong to the scope of protection of the present application.

[0078] The connectors in this article are a general term for dynamic connectors and static connectors, wherein the connector that is stationary relative to the unit chamber 20 is the static connector, and the connector that moves relative to the unit chamber 20 is the dynamic connector. In the unit assembly, the connectors include unit main circuit connectors, main circuit incoming line connectors 9, auxiliary circuit connectors, etc. The unit main circuit connectors are divided into unit main circuit dynamic connectors 2 and unit main circuit static connectors 1, which are plug-connected, and the auxiliary circuit connectors are divided into auxiliary circuit dynamic connectors 27 and auxiliary circuit static connectors 8, which are plug-connected.

[0079] Embodiment 1, as Figures 1 to 23 As shown, taking a 1 / 3 unit assembly with a cabinet width of 600mm and a unit module of 150mm and a 63A / 3-phase unit main circuit static plug-in 1, a unit main circuit dynamic plug-in 2, and a power distributor 3 adapted to the unit assembly as an example, the technical solution of the present application is described in detail.

[0080] like Figures 1 to 5 As shown, a unit main circuit static plug-in includes an insulating shell 6 and a plurality of plug-in rows 4. The plug-in rows 4 are installed in the insulating shell 6 and are arranged horizontally in a line in the insulating shell 6. The plug-in rows 4 are arranged horizontally, and the plug-in end of the plug-in row 4 is its front end. The rear end of the plug-in row 4 is the connection terminal of the connecting wire 5, which is located at the rear of the insulating shell 6.

[0081] The upper side of the rear part of the insulating housing 6 has a plurality of vertical outlet channels 7 corresponding to the wiring terminals of each plug-in row 4, so that the wires 5 connected to the plug-in row 4 can be vertically outlet from the corresponding outlet channels 7. The lower side of the rear part of the insulating housing 6 also has a plurality of vertical outlet channels 7 corresponding to the wiring terminals of each plug-in row 4, so that the wires 5 connected to the plug-in row 4 can be vertically outlet from the corresponding outlet channels 7. Of course, such outlet structures and outlet methods are not the only ones, and other outlet structures and outlet methods can also be used.

[0082] The insulating shell 6 is a split assembly structure, including multiple insulating shell monomers 6-1. Multiple insulating shell monomers 6-1 are assembled in sequence in the left and right directions to form an insulating shell assembly. Each plug-in row 4 is installed between two adjacent insulating shell monomers 6-1 on the left and right. The insulating shell assembly is combined together through an external coupling structure.

[0083] The external connection structure of the insulating shell 6 of the unit main circuit static plug-in 1 is a clamp 6-2, which is sleeved on the outside of the insulating shell assembly to combine the insulating shell assembly together. The clamp 6-2 is assembled from two upper and lower clamp monomers, or the clamp 6-2 is assembled from two left and right clamp monomers. There is a concave-convex matching structure between the clamp 6-2 and each insulating shell monomer 6-1, which is used to position the front and rear positions of the insulating shell monomer 6-1.

[0084] The concave-convex matching structure between the clamp 6-2 and each insulating shell monomer 6-1 is specifically: the upper side and the lower side of each insulating shell monomer 6-1 have a groove 6-3 for forming a positioning groove on the outside of the insulating shell assembly, and the inner side of the clamp 6-2 has a positioning convex strip embedded in the positioning groove. Alternatively, the upper side or the lower side of each insulating shell monomer 6-1 has a groove 6-3 for forming a positioning groove on the outside of the insulating shell assembly, and the inner side of the clamp 6-2 has a positioning convex strip embedded in the positioning groove.

[0085] The two clamping hoop monomers are assembled together through the buckle knot structure on the clamping hoop monomers; or, the two clamping hoop monomers are assembled together through fasteners such as screws.

[0086] The clamp 6-2 is provided with a mounting hole 6-4 for mounting the static plug-in unit 1 for the main circuit of the unit.

[0087] The wiring terminal of the plug-in strip 4 is provided with a wiring hole and a bolt fastening assembly installed through the wiring hole for connecting the wire 5 .

[0088] Of course, it is not ruled out that the insulating shell assembly is combined together through the self-combination structure of the insulating shell monomer 6-1. For example, the self-combination structure is specifically a snap-on and snap-on fitting structure. The two adjacent insulating shell monomers 6-1 on the left and right are respectively provided with snap-on and snap-on fitting structures, so that the two adjacent insulating shell monomers 6-1 on the left and right can be snapped together through the snap-on and snap-on fitting structure, so that the insulating shell assembly is combined together through the snap-on and snap-on fitting structure; of course, other specific schemes in the prior art can also be adopted to realize that the insulating shell assembly is combined together through the self-combination structure of the insulating shell monomer 6-1.

[0089] Of course, it is not ruled out that the external connecting structure is a pin fastener or a bolt fastener that passes through each insulating shell monomer 6-1, and the pin fastener or the bolt fastener passes through each insulating shell monomer 6-1 to connect the insulating shell assembly together; of course, other specific schemes in the prior art can also be adopted to realize that the insulating shell assembly is connected together through the external connecting structure.

[0098] The length of the terminal 13 of the wire 5 is 18 mm. In order to better ensure the electrical clearance, a heat shrink tube is put on the terminal 13, especially the wire 5 connecting the unit main circuit static plug-in 1 and the main circuit incoming line connector 9 of the corresponding unit No. 1. There are many wires 5 and the distance between them is close.

From left to right, they are auxiliary circuit static plug-in No. 1, auxiliary circuit static plug-in No. 2 and auxiliary circuit static plug-in No. 3. Auxiliary circuit static plug-in No. 1 corresponds to unit No. 1. Because the space of the frame rear plate 12 of the distributor frame is limited, it can only meet the arrangement of the auxiliary circuit user wiring components 18 corresponding to the auxiliary circuit static plug-ins No. 2 and No. 3. Therefore, a rear-outlet additional frame 19 is also provided at a position between the main circuit outgoing user wiring components 10 and the main circuit incoming line connector 9 on the frame rear plate 12 of the distributor frame, and the auxiliary circuit user wiring components 18 corresponding to the auxiliary circuit static plug-in No. 1 are arranged on the rear-outlet additional frame 19.

[0106] The insulating shell 6 of the unit main circuit dynamic plug-in 2 is also a split assembly structure, which is the same as the split assembly structure of the insulating shell 6 of the unit main circuit static plug-in 1, including multiple insulating shell monomers 6-1 and clamps 6-2. Multiple insulating shell monomers 6-1 are assembled in sequence in the left and right directions to form an insulating shell assembly. Each plug assembly is installed between two adjacent insulating shell monomers 6-1 on the left and right. The clamp 6-2 is sleeved on the outside of the insulating shell assembly to combine the insulating shell assembly together.

[0107] The upper and lower sides of each insulating shell monomer 6-1 of the unit main circuit dynamic plug-in 2 have grooves 6-3 for forming a positioning groove on the outside of the insulating shell assembly.

[0109] The clamp 6-2 and each insulating shell monomer 6-1 have a concave-convex matching structure, specifically: the upper and lower sides of each insulating shell monomer 6-1 have a groove 6-3 for forming a positioning groove on the outside of the insulating shell assembly, and the inner side of the clamp 6-2 has a positioning convex strip embedded in the positioning groove.

[0110] The clamp 6-2 is provided with a mounting hole 6-4 for mounting the unit main circuit dynamic plug-in 2.

[0111] The conductive plugs 14 of each phase of the unit main circuit input and output of the unit main circuit dynamic plug-in 2 are completely consistent with the centers of the plug-in rows 4 of each phase of the unit main circuit input and output of the unit main circuit static plug-in 1, and the two are plug-in connected.

[0112] The unit assembly can apply the applicant's patent application numbers 202021590057.9, 202122641977.X's hand-cranked propulsion mechanism 23, the applicant's patent application number 202123169949.9's hand-pull propulsion mechanism, and the applicant's patent application number 202322485997.1's sliding column hook guide unit structure, so that the unit assembly can achieve three-position display, position locking, propulsion mechanism position locking, circuit breaker closing, drawer locking, and propulsion mechanism locking with high security.

[0113] The unit assembly of the present embodiment 1 is a unit assembly that is manually pulled and propelled.

[0114] The dimensions of the power distributor 3 of this embodiment can be 134mm in height, 550mm in width, and 60-70mm in depth, and the unit chamber 20 of the 150-module 1 / 3 unit assembly is 450mm deep. The rated current of the incoming main circuit of the 63A / 3-phase 1 / 3 power distributor is 200A, and the main circuit incoming connector 9 of the power distributor 3 is specifically a main circuit incoming connector 9 with a rated current of 200A, which is used to plug and connect with the vertical bus 16 at the rear of the cabinet to enter the main circuit. The power distributor 3 has a total of 3 main circuit incoming connectors 9, which are arranged on the left side of the power distributor 3, and each main circuit incoming connector 9 corresponds to one phase of the main circuit incoming line, and each main circuit incoming connector 9 is connected to 3 units 21 through 3 unit main circuit static plug-ins 1.

[0115] In the prior art, each unit 21 is equipped with two unit main circuit connectors, one for the incoming line of the unit main circuit and one for the outgoing line of the unit main circuit. The main circuit incoming line connector 9 and the unit main circuit static plug-in 1 for the incoming line of the unit main circuit are connected by 2 wires per phase, a total of 18 wires of 6 mm 2 The main circuit input connector 9 of the power distributor 3 is concentrated at the position corresponding to the unit main circuit static connector 1 of unit 1. There are 12 6mm ... 2Wire 5, and the depth of the power distributor 3 can only be between 60 and 70mm, and the routing of the wire 5 is very difficult. Moreover, the inner width of the 1 / 3 unit is only 155mm, and the height of the back plate of the unit 21 is only 115.8mm. It is also necessary to arrange 20 connection points of auxiliary circuit connectors on the unit 21 and the power distributor 3. Among them, the auxiliary circuit static plug-in 8 on the power distributor 3 is connected to the auxiliary circuit user wiring piece 18 through 20 1.5㎡ wires 5. The three auxiliary circuit static plug-ins 8 are connected with 60 1.5㎡ wires 5 in total. The auxiliary circuit static plug-in 8 occupies 40mm of the height of the power distributor 3. The outer dimensions of the unit main circuit connector are very small to solve this problem.

[0116] The unit main circuit static plug-in 1 of this embodiment reduces the width of the power distributor 3 through the integrated design of the unit main circuit input and output lines 6, and leaves space for the arrangement of the auxiliary circuit static plug-in 8. Similarly, the unit main circuit dynamic plug-in 2 is designed to be integrated with the unit main circuit input and output lines 6 to reduce the width, and also leaves space for the arrangement of the auxiliary circuit dynamic plug-in 27.

[0117] The plug-in conductor of the unit main circuit static plug-in 1 adopts the design of plug-in row 4 instead of conductive plug 14, and the unit main circuit static plug-in 1 adopts the design of up and down routing of wire 5 to ensure the electrical clearance between the unit main circuit static plug-in 1 and the main circuit incoming line connector 9, and facilitate the routing of wire 5. Corresponding to unit No. 1, the electrical clearance between the unit main circuit static plug-in 1 and the main circuit incoming line connector 9 can meet the standard safety distance requirement of 12.5 to 16 mm.

[0118] The unit main circuit static plug-in unit 1 is designed with the plug-in row 4 arranged horizontally, thereby reducing the height dimension of the unit main circuit static plug-in unit 1.

[0119] The insulating shell 6 of the unit main circuit static plug-in 1 adopts a split assembly structure, which realizes the modularization of the unit main circuit static plug-in 1, and can be assembled to obtain unit main circuit static plug-ins 1 with different numbers of phases. Moreover, this design can also facilitate wiring while ensuring electrical clearance and reducing the thickness of the unit main circuit static plug-in 1, that is, the plug-in row 4 and the insulating shell 6 are assembled after the connection between the wire 5 and the plug-in row 4 is completed.

[0120] The main circuit incoming line connector 9, the unit main circuit static plug-in 1 and the main circuit outgoing line user wiring piece 10 of this embodiment are all designed with a miniaturized structure, which reduces the space occupation and facilitates the routing of the wire 5. The electrical clearance is greater than 12.5mm. Among them, the electrical clearance of the main circuit incoming line connector 9 is 14mm, which is greater than the standard requirement of 12.5mm, ensuring that the power frequency withstand voltage reaches the qualified standard of 2500V.

[0121] like Fig.23As shown, the 1 / 3 unit of the 150mm module realizes 12 layers and 36 circuits of a switch cabinet equipment, which increases the small current control circuits of the switch cabinet equipment and reduces the number of switch cabinet equipment. It can be applied to 5.5kVA motor control circuits in application fields such as petrochemical, steel, tap water, sewage, shipbuilding, nuclear power, etc., greatly reducing the application of 1 / 2 units. The current of unit 21 can reach 63A. The operation safety of unit 21 is extremely high, the reliability is greatly improved, and the economic value is considerable.

[0122] Economic cost analysis: In the prior art, a 5kVA motor control circuit uses a 1 / 2 unit assembly, and one switch cabinet device has only 12 layers and 24 circuits. The 1 / 3 unit of the 150mm module of this embodiment realizes 12 layers and 36 circuits of a switch cabinet device. Using 10,000 1 / 3 units of this embodiment only requires 278 switch cabinet devices, while if 1 / 2 units are used, 417 units are required. The use of 1 / 3 units can reduce 139 switch cabinet devices. The cabinet cost of one switch cabinet device including the vertical bus 16 and the horizontal bus is as high as 7,000 yuan. In addition, one switch cabinet device occupies 0.6 square meters. The use of 1 / 3 units can greatly reduce the desktop of the switch cabinet device and greatly reduce the floor space occupied by the switch cabinet device.

[0123] Embodiment 2, a unit main circuit static plug-in, a power distributor and a multi-circuit unit assembly, is basically the same as Embodiment 1, except that: the multi-circuit unit assembly of Embodiment 2 is a 1 / 3 unit assembly that is manually propelled, while Embodiment 1 is a 1 / 3 unit assembly that is manually propelled, such as Fig.24 As shown, a hand-cranked propulsion mechanism 23 for hand-cranked propulsion is installed on the unit 21 of the 1 / 3 unit assembly of the second embodiment, and correspondingly, a groove-shaped positioning member matching the hand-cranked propulsion mechanism 23 is installed on the unit chamber 20.

In addition to the distributor frame body of embodiment 1 for installing the unit main circuit static plug-in 1, the auxiliary circuit static plug-in 8 and the main circuit incoming line connector 9, the distributor frame of this embodiment 3 also includes a side-outlet frame 24.

[0130] Embodiment 6, a unit main circuit static plug-in, a power distributor and a multi-circuit unit assembly, is basically the same as Embodiment 4, except that: Fig.30 and 31 As shown, the cabinet width of the 1 / 2 unit assembly of the present embodiment 6 is 500 mm, while the cabinet width of the 1 / 2 unit assembly of the embodiment 4 is 600 mm.

[0131] Example 7, a unit main circuit static plug-in, power distributor and multi-circuit unit assembly, is basically the same as Example 6, both are 1 / 2 unit assemblies with a cabinet width of 500mm, except that: Fig.32 and 33 As shown, the unit module of the 1 / 2 unit assembly of this embodiment 7 is 200mm.

The RJ45 communication dynamic connector 25 is installed on the unit 21, and the RJ45 communication static connector 26 is installed on the power distributor 3.

[0132] If the RJ45 communication connector is replaced with an auxiliary circuit connector, it can meet the layout of the auxiliary circuit connectors of 48 wiring points. It has a large application volume in specific equipment application scenarios, such as subway application scenarios. It can replace the 1 / 2 unit assembly with a cabinet width of 500mm and a unit module of 200㎜, which reduces the use of horizontal busbars and reduces the floor space occupied by switch cabinet equipment.

[0133] Embodiment 8, a unit main circuit static plug-in, a power distributor and a multi-circuit unit assembly, is basically the same as Embodiment 1, except that: Figures 34-37 As shown, the power distributor 3 of this embodiment 8 is installed with a unit main circuit static plug-in 1 with separate incoming and outgoing lines.

The unit main circuit static plug-in 1 for the unit main circuit incoming line and outgoing line has 4 phases, and the auxiliary circuit static plug-in 8 and the RJ45 communication static plug-in 26 are installed on the unit main circuit static plug-in 1.

[0134] Correspondingly, the unit main circuit dynamic plug-in 2 on the unit 21 is also a unit main circuit dynamic plug-in 2 with separate incoming and outgoing lines. One unit has two unit main circuit dynamic plug-ins 2, one unit main circuit dynamic plug-in 2 is used for the unit main circuit incoming line, and the other unit main circuit dynamic plug-in 2 is used for the unit main circuit outgoing line.

[0135] The multi-circuit unit assembly of this embodiment 8 is a 1 / 2 unit assembly with a unit module of 200 mm. The unit chamber 20 of the 1 / 2 unit assembly has two 1 / 2 units. The auxiliary circuit dynamic plug-in 27 and the RJ45 communication dynamic plug-in 25 are installed on the unit main circuit dynamic plug-in 2 of the back panel of the unit 21.

[0136] Embodiment 9: A unit main circuit static plug-in, a power distributor and a multi-circuit unit assembly, such as Fig.38 and 39As shown, it is basically the same as Example 8. The power distributor 3 of this Example 9 is installed with a unit main circuit static plug-in 1 with separate incoming and outgoing lines. There are 4 unit main circuit static plug-ins 1, and every 2 unit main circuit static plug-ins 1 form a group, corresponding to a unit 21, wherein the unit main circuit static plug-in 1 on the left is used for the unit main circuit incoming line, and the unit main circuit static plug-in 1 on the right is used for the unit main circuit outgoing line. The multi-circuit unit assembly of this Example 9 is a 1 / 2 unit assembly, and the unit chamber 20 of the 1 / 2 unit assembly has 2 1 / 2 units. The difference from Example 8 is that: the unit module is 150mm, there is no RJ45 communication static plug-in 26, the number of phases of the unit main circuit static plug-in 1 for the unit main circuit incoming line and outgoing line are both 3 phases, the rated current of the unit 21 main circuit is 100A, the cross-sectional area of ​​the plug row 4 of the unit main circuit static plug-in 1 is 3×20mm, and the diameter of each wire 5 connecting the unit main circuit static plug-in 1 is 6mm 2 Change to 10mm 2 .

[0137] The 1 / 2 unit of the 150mm module of the present embodiment 9 can be applied to the motor control circuit of forward and reverse operation, and the operating current is not more than 63A, and is normally below 45A, but the user requires a short-time tolerance test of 1s8kA.

[0138] If the 1 / 2 unit of the 125A / 3-phase copper busbar wiring in the prior art is used, the unit module of the 1 / 2 unit needs to be 200mm, while the 1 / 2 unit of the 100A / 3-phase conductor 5 wiring in this embodiment can have a unit module of 150mm.

[0139] Only 417 switch cabinet devices are needed to use 10,000 1 / 2 units with a 150 mm module of the present embodiment, while 555.56 units are needed if 1 / 2 units with a 200 mm module are used. The use of the 1 / 2 units with a 150 mm module of the present embodiment can reduce 138.56 switch cabinet devices. The cabinet cost of one switch cabinet device including the vertical busbar 16 and the horizontal busbar is 7,000 yuan. In addition, one switch cabinet device occupies 0.6 m2. The use of the 1 / 2 units with a 150 mm module of the present embodiment can greatly reduce the number of switch cabinet devices and greatly reduce the floor space occupied by the switch cabinet devices.

[0140] The reliability and safety of the 1 / 2 unit of the 150 mm module of this embodiment can be fully guaranteed when used in a motor control loop.

[0141] In the prior art, the 1 / 2 unit of the 125A / 3-phase copper busbar wiring can only arrange auxiliary circuit connectors with a maximum of 24 wiring points in a 200mm unit module, which cannot meet the requirement of 32 wiring points of the auxiliary circuit components of the motor control loop. However, the 1 / 2 unit of the 150mm module of the present embodiment can arrange auxiliary circuit connectors with a maximum of 32 wiring points.

[0142] In summary, the 1 / 2 unit of the 150 mm module of the present embodiment 9 solves the application technical problems of the motor control circuit, reduces the number of switch cabinet equipment, reduces the floor space, and reduces the total cost of equipment application.

[0143] The 100A, 150mm module 1 / 2 unit of this embodiment 9 can meet the technical requirements of users in specific scenarios, but currently there is no 150mm module 1 / 2 unit of this current level in the industry.
