In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

An embodiment of the present disclosure provides a bus duct, which is applied in a power distribution system. Busway is a high-current transmission equipment formed by metal plates such as copper plates or aluminum plates as conductor plates, supported by insulating materials, and matched with metal shells. It has increasingly replaced cables in power transmission trunk line projects. Correspondingly, the power distribution system includes a plug-in box, which can also be called a power-taking box, and is used to be plugged into the bus duct to take power from it.

For example, a power distribution system including a bus duct can be applied in an Internet Data Center (IDC for short). The specific application can be that the bus duct is arranged in the computer room of the IDC, and the external power distribution (such as mains power and batteries, etc.) After it is introduced into the IDC equipment room, it is connected to the bus duct. The plug-in box is inserted in the bus duct to take power from it. The plug-in box includes a power transmission port. The cables are inserted into the power transmission port of the plug-in box and lead to each cabinet (such as each column head cabinet) in the IDC room. Cabinet power supply.

The following is a further introduction to the busway.

Fig. 1 is a schematic structural diagram of a bus duct, referring to Fig. 1, in this embodiment, the bus duct includes: a housing 110 and a conductive plate 120, the housing 110 has a plurality of insertion slots 111 distributed along the length direction, and The notches of the plurality of insertion slots 111 are located on the same side of the housing 110 .

Fig. 2 is a cross-sectional view of the bus duct. With reference to Fig. 2, in this embodiment, the conductive plate 120 is located in the socket slot 111, and the conductive plate 120 is insulated from the housing 110. The conductive surface 121 that the conductive portion 220 of the connector contacts. There are two conductive plates 120 in the insertion slot 111 , and the polarities of the two conductive plates 120 are different from each other.

One side of the housing 110 has an insertion slot 111 for accommodating the conductive plate 120 and providing a base for installing the conductive plate 120 . The conductive plate 120 is installed in the socket slot 111, and the conductive plate 120 is insulated from the housing 110 to ensure the safety of electricity use. The conductive plate 120 has a power-connecting surface 121, and the power-connecting surface 121 is exposed in the socket slot 111. It is used to contact the conductive part 220 of the plug joint 210 of the plug box 20 to realize the electrical connection between the bus duct and the plug box 20 . Since there are two conductive plates 120 in the socket slot 111, and the polarities of the two conductive plates 120 are different from each other, so when a plug connector 210 is plugged into a socket slot 111, the plug connector 210 can Make electrical connections with the two polarities respectively (see Figure 3). In this way, the number of insertion slots 111 is effectively reduced, making the structure of the bus duct simpler, which is beneficial to realize the miniaturization design of the bus duct.

In addition, after the plug joint 210 of the plug box 20 is plugged into the slot 111 along the depth direction of the slot 111 , the conductive portion 220 of the plug joint 210 can be electrically connected to the conductive plate 120 . Surface 121 is in contact with each other, and the quick electrical connection between the bus duct and the plug box 20 can be realized without other operations.

In one application, the side where the notch of the insertion slot 111 is located is the insertion side of the bus duct, and the side of the bus duct facing away from the insertion side is the installation side, and the installation side of the bus duct can be installed on the IDC On the top of the machine room, the plug-in slot 111 of the busway faces the ground of the IDC machine room. The technician can hold the plug-in box 20 and insert the plug-in connectors 210 of the plug-in box 20 into the bus-way, for example, insert the plug-in connectors 210 one by one. to the plug slot 111 of the bus duct, so as to realize the power taking of the plug box 20 in the bus duct.

In this embodiment, the bus duct may be a small bus duct, that is, a bus duct whose transmission current is within 800A. Certainly, the bus duct may also be a large bus duct, and the embodiment of the present application does not limit the specific type of the bus duct.

It can be seen from the foregoing that the arrangement of the conductive plate 120 in the socket slot 111 is the key to realizing the "two poles in one slot" of the bus duct. The arrangement of the conductive plate 120 will be introduced below.

Referring to FIG. 2 , in this embodiment, the plurality of insertion slots 111 includes at least one first insertion slot 1111 , and there are two conductive plates 120 in the first insertion slot 1111 , and the two conductive plates 120 are respectively located in the first insertion slot 1111 . At two opposite groove walls of the insertion groove 1111 , the two conductive plates 120 are opposite and have a distance therebetween.

In the above implementation manner, the first insertion slot 1111 is a type of insertion slot 111 . The first insertion slot 1111 corresponds to the second and third insertion slots 111 counted from left to right in FIG. 2 . In the first plug slot 1111, there are two conductive plates 120, and the power-connecting surfaces 121 of the two conductive plates 120 are arranged at intervals relative to each other, and can respectively contact the conductive parts 220 of the plug connector 210, thereby realizing "one slot with two poles", Make the structure of the busway more compact.

Continuing to refer to FIG. 2 , in this embodiment, the plurality of insertion slots 111 further include a second insertion slot 1112 , and a conductive plate 120 is provided in the second insertion slot 1112 , and the conductive plate 120 is located in the second insertion slot At one slot wall of 1112 , the conductive plate 120 is opposite to the other slot wall of the second insertion slot 1112 with a distance therebetween.

In the above implementation manner, the second insertion slot 1112 is another type of the insertion slot 111 . The second insertion slot 1112 corresponds to the first insertion slot 111 counted from left to right in FIG. 2 . In the second insertion slot 1112 , there is a conductive plate 120 . The electric connection surface 121 of the conductive plate 120 is spaced apart from the slot wall of the insertion slot 111 and can be in contact with the conductive portion 220 of the plug connector 210 .

That is to say, the insertion slot 111 has two types, one type is the first insertion slot 1111 with two conductive plates 120 therein, and the other type is the second insertion slot 1112 with one conductive plate 120 therein. The selection of the type of the socket slot 111 is related to the number of the conductive plates 120 of the bus duct. Classification is discussed below.

If the number of conductive plates 120 of the busway is an even number, then all the socket slots 111 can be the first socket slots 1111, or some of the socket slots 111 are the first socket slots 1111, and the remaining even number sockets The slot 111 is a second insertion slot 1112 .

If the number of conductive plates 120 of the bus duct is an odd number, then the plurality of insertion slots 111 include both the first insertion slot 1111 and the second insertion slot 1112 . For example, there is one second insertion slot 1112 , and the rest are all first insertion slots 1111 .

Further, the number of conductive plates 120 is related to the standard of the power distribution system. Exemplarily, the conductive plate 120 is a copper plate for transmitting electric power. For example, if the power distribution system is a three-phase five-wire system, the bus duct includes five conductive plates 120 corresponding to three phase lines, one neutral line, and one ground line respectively. If the power distribution system is a three-phase four-wire system, the bus duct includes four conductive plates 120 corresponding to three phase lines and one neutral line, or three phase lines and one ground line.

In this embodiment, if the power distribution system is a three-phase five-wire system, the bus duct includes five conductive plates 120 , that is, the number of conductive plates 120 is an odd number. In this case, the insertion slot 111 includes two first insertion slots 1111 and one second insertion slot 1112, wherein the two first insertion slots 1111 respectively accommodate the conductive plates 120 corresponding to the three phase lines (phase Pole conductive plate) and a conductive plate 120 (zero line conductive plate) corresponding to a neutral line, and a second socket 1112 accommodates a conductive plate 120 (ground electrode conductive plate) corresponding to a ground line. If the power distribution system is a three-phase four-wire system, the bus duct includes four conductive plates 120 , that is, the number of conductive plates 120 is an even number. In this case, the insertion slot 111 includes two first insertion slots 1111 , respectively accommodating the conductive plates 120 corresponding to the three phase lines and the conductive plate 120 corresponding to one neutral line.

Of course, the arrangement of the above-mentioned conductive plate 120 is only an example, and the present disclosure does not limit it.

Exemplarily, the distance between the two conductive plates 120 in the first insertion slot 1111 is less than or equal to 12.5 millimeters.

In the above implementation manner, the distance d1 between the contacting surfaces 121 of the two conductive plates 120 in the first socket slot 1111 is less than or equal to 12.5 millimeters, so that the bus duct can meet the IP2X standard, so as to avoid the technical personnel's hand If it penetrates into the distance d1, it will cause an electric shock.

Exemplarily, the distance between the conductive plate 120 in the second insertion slot 1112 and the opposite slot wall is less than or equal to 12.5 millimeters.

In the above implementation manner, the distance d2 between the electrical connection surface 121 of the conductive plate 120 in the second socket slot 1112 and the opposite slot wall is less than or equal to 12.5 mm, so that the bus duct can meet the IP2X standard to avoid technical A person's hand penetrates into this distance d2, causing an electric shock.

It should be noted that if the conductive plate in the second socket 1112 is a ground conductive plate, even if the technician's hand goes in, no electric shock will occur. Therefore, the conductive plate 120 and the wall of the socket 111 The distance d2 between them may also not be limited.

Continuing to refer to FIG. 2 , in this embodiment, the bus duct further includes an insulating support 130 located in the insertion slot 111 , and the length direction of the insulation support 130 is consistent with the length direction of the insertion slot 111 . The conductive plate 120 is located in the insulating bracket 130 , and the power-connecting surface 121 of the conductive plate 120 is exposed in the socket slot 111 .

In the above implementation, the insulating bracket 130 is installed in the socket slot 111 to provide an installation basis for the conductive plate 120, and the conductive plate 120 is installed on the insulating bracket 130 to realize the insulation between the conductive plate 120 and the housing 110. Install.

Exemplarily, both the insulating support 130 and the conductive plate 120 are strip-shaped, the conductive plate 120 is located in the insulating support 130, and the insulating support 130 half-wraps the conductive plate 120, so that the conductive plate 120 has a The electric connection surface 121 is so as to be in contact with the conductive portion 220 of the plug box 20 to conduct conduction.

It should be noted that the number of insulating brackets 130 is the same as the number of conductive plates 120 because the insulating brackets 130 are used to realize the insulating installation of the conductive plates 120 in the socket slots 111 . That is to say, there are two insulating brackets 130 in the first slot 1111 , and one insulating bracket 130 in the second slot 1112 .

Continuing to refer to FIG. 2 , in this embodiment, the insulating bracket 130 has an accommodating slot 131 extending along its length, and the notch of the accommodating slot 131 is located in the insertion slot 111 . The conductive plate 120 is located in the accommodating through groove 131 , and the electrical connection surface 121 of the conductive plate 120 is exposed in the insertion groove 111 through the notch of the accommodating through groove 131 .

In the above implementation, the insulating bracket 130 has a receiving through groove 131, and the receiving through groove 131 is used to provide an installation space for the conductive plate 120. It is exposed in the socket slot 111, so that the insulating installation between the conductive plate 120 and the housing 110 is realized, and the safety of electricity usage is ensured.

In this embodiment, the groove wall of the accommodating through groove 131 has a convex stop 132, the convex stop 132 protrudes from the groove wall of the accommodating through groove 131, and the convex stop 132 is located at the notch of the accommodating through groove 131 place. The power-connecting surface 121 of the conductive plate 120 has a concave notch 122 , and the concave notch 122 and the convex notch 132 are plugged together.

In this embodiment, the convex notch 132 and the concave notch 122 can cooperate with each other, so that the conductive plate 120 is snapped into the accommodating through groove 131, thereby achieving a stable installation between the conductive plate 120 and the insulating bracket 130 .

FIG. 4 is a cross-sectional view of the bus duct, and the difference between FIG. 4 and FIG. 2 mainly lies in the relevant structure of the conductive plate 120 . Referring to FIG. 4 , in this embodiment, one side of the conductive plate 120 has an electric connection spring 123 . One end of the electric connection elastic piece 123 extends away from the conductive plate 120 , and a side of the electric connection elastic piece 123 away from the conductive plate 120 is the electric connection surface 121 .

In the above-mentioned implementation manner, the electric connection spring 123 is connected to the conductive plate 120 . When the plug connector 210 of the socket box 20 is plugged into the socket slot 111, the plug connector 210 of the socket box 20 can squeeze the electric connection elastic piece 123, so that the electric connection elastic piece 123 is elastically deformed, thereby pressing against the socket connector. The conductive portion 220 of the busbar 210 further realizes stable contact between the electric connection surface 121 on the electric connection spring 123 and the plug connector 210 , which improves the stable electrical connection between the bus duct and the plug box 20 .

Exemplarily, when one end of the electric connection spring 123 extends away from the conductive plate 120 , it also extends away from the notch of the insertion slot 111 . Such a design can increase the insertion stroke of the plug connector 210 into the socket slot 111 , thereby avoiding premature power connection of the plug connector 210 when plugged into the socket slot 111 .

FIG. 5 is a cross-sectional view of the bus duct. The difference between FIG. 5 and FIG. 2 mainly lies in the relevant structure of the conductive plate 120 . Referring to FIG. 5 , in this embodiment, one side of the conductive plate 120 has an electrical connection protrusion 124 . The power connection protrusion 124 protrudes away from the conductive plate 120 , and the side of the power connection protrusion 124 away from the conductive plate 120 is the power connection surface 121 .

In the above implementation manner, the electrical connection protrusion 124 is connected to the conductive plate 120 . When the plug joint 210 of the plug box 20 is plugged into the slot 111, the plug joint 210 of the plug box 20 and the electric protrusion 124 are squeezed against each other, so that the two are in close contact with each other, and then the connection is realized. The stable contact between the electric connection surface 121 on the electric elastic piece 123 and the plug connector 210 improves the stable electrical connection between the bus duct and the plug box 20 .

Continuing to refer to FIG. 5 , in this embodiment, when the conductive plate 120 is a ground conductive plate, the distance between the electrical connection protrusion 124 and the notch of the insertion slot 111 is the first distance d3. When the conductive plate 120 is a phase conductive plate or a neutral conductive plate, the distance between the electrical connection protrusion 124 and the notch of the socket 111 is the second distance d4, and the first distance d3 is smaller than the second distance d4.

In the above implementation, since the first distance d3 is smaller than the second distance d4, during the process of inserting the plug connector 210 into the socket slot 111, the conductive part 220 of the plug connector 210 is the first to connect with the contacting protrusion of the ground conductive plate. With the movement of the plug connector 210, the conductive part 220 of the plug connector 210 will then contact the electric connection protrusion 124 of the phase pole conductive plate or the neutral line conductive plate. In this way, the priority grounding of the plug connector 210 can be realized, which meets the safety standard of grounding first.

It should be noted that the first distance d3 and the second distance d4 can be determined by the relative positions of the electrical connection protrusions 124 on the conductive plate 120 . For example, the contact protrusion 124 is close to the notch of the insertion slot 111 to make the first distance d3 smaller, otherwise the first distance d3 is made larger, and the second distance d4 is the same. Besides, the first distance d3 and the second distance d4 can be determined by the relative position between the conductive plate 120 and the notch of the insertion slot 111 . For example, the conductive plate 120 is close to the notch of the insertion slot 111 to make the first distance d3 smaller, otherwise the first distance d3 is made larger, and the same is true for the second distance d4.

Figure 6 is a cross-sectional view of the busway, the difference between Figure 6 and Figure 2 is that the busway also includes a dust cover 140, the dust cover 140 is located at the notch of the insertion slot 111, and covers the slot of the insertion slot 111 mouth.

Covering the insertion slot 111 with the dustproof cover 140 can effectively prevent sundries from entering the insertion slot 111 from the notch of the insertion slot 111 . It is easy to understand that, although the dust cover 140 is disposed at the notch of the insertion slot 111 , the dust cover 140 should not affect the insertion of the plug connector 210 of the plug box 20 .

In this embodiment, the bus duct can not only be used to transmit electric power, but also can be used to accommodate additional wire harnesses, such as weak wires, network cables, and the like. Referring to FIG. 2 , the housing 110 also has an additional slot 112 along the length direction. The opening of the additional slot 112 is located on one side of the housing 110 along the length direction and is on a different side from the opening of the insertion slot 111 .

In the above implementation manner, the notch of the additional slot 112 is located on one side of the housing 110 along the length direction, and is located on a different side from the notch of the insertion slot 111 . This is because the notch of the plug-in slot 111 is used for plugging in the plug-in connector 210 of the plug-in box 20, so in order not to affect the plug-in connection of the plug-in connector 210, the side where the notch of the additional slot 112 is located is different from that of the plug-in slot 111. side of the notch.

For example, if the bus duct is suspended on the top of the IDC machine room, then the notch of the plug slot 111 is located at the lower side of the bus duct towards the ground, the installation side of the bus duct is located at the upper side towards the ceiling, and the notch of the additional slot 112 is located at the lower side of the bus duct. The left or right side of the slot.

In one example, in order to close the additional slot 112, the housing 110 further includes an additional slot cover 113, and the additional slot cover 113 is covered on the notch of the additional slot 112, for example, can be covered on the additional slot 112 by snap-fitting. notch.

In one example, for the additional wire harness to be introduced into the additional slot 112 and pass through the additional slot 112, correspondingly, there is a gap between the additional slot 112 and the additional slot cover 113 for the additional wire harness to pass through. .
