The present utility model proposes a bus bar 100, which aims to shorten the current path of the bus bar 100 to reduce the electrical loss.
The specific structure of the bus bar 100 and hydrogen-producing power supply product of the present utility model will be described below:
referring to fig. 1 in combination, in one embodiment of a bus 100 of the present utility model, the bus 100 includes an output interface 10 and a bus bar 20; the bus bar 20 includes a lateral bus bar 21 and a longitudinal bus bar 22, the lateral bus bar 21 having a plurality of unit input bars 2112 spaced apart along a length thereof, each unit input bar 2112 for electrically connecting with an output of a power unit; the longitudinal bus bar 22 is electrically connected with any one of the transverse bus bars 21, and the longitudinal bus bar 22 is located between any two adjacent unit input bars 2112; the bus bar 20 is provided with at least two longitudinal bus bars 22 of at least two bus bars 20 connected in parallel to the output interface 10.
It can be appreciated that in the bus bar 100 according to the present utility model, the longitudinal bus bar 22 is electrically connected to any one of the transverse bus bars 21, and the longitudinal bus bar 22 is located between any two adjacent unit input bars 2112, so that the currents of the unit input bars 2112 located at both sides of the longitudinal bus bar 22 can be simultaneously conducted from the ends of the transverse bus bars 21 to the longitudinal bus bar 22, thereby shortening the current path of the bus bar 100 and reducing the electrical loss.
In addition, by providing at least two bus branches 20 to connect the currents of a plurality of power units in parallel to the output interface 10 through the at least two bus branches 20, compared with the mode of directly adopting the large-size bus 100 to connect the currents, the problem of reduced current passing capability caused by the skin effect of the currents can be avoided, therefore, the consumption of the bus 100 can be reduced under the condition of the same current carrying requirement, the cost and the occupied space of the bus 100 can be reduced, and the size of a cabinet machine for installing the bus 100 can be reduced.
For example, the length of the transverse bus bar 21 is 20cm, the longitudinal bus bar 22 is electrically connected to the middle of the transverse bus bar 21, and two ends of the transverse bus bar 21 are provided with one unit input bar 2112, and the currents of the two unit input bars 2112 can be respectively conducted from two ends of the transverse bus bar 21 to the longitudinal bus bar 22, so that the currents of the two unit input bars 2112 can be conducted to the longitudinal bus bar 22 only after flowing through the transverse bus bar 21 of 10 cm; in the conventional manner, the longitudinal bus bar 22 is disposed at one end of the transverse bus bar 21, one unit input bar 2112 is disposed at the other end and the middle of the transverse bus bar 21, and two unit input bars 2112 can respectively flow from the other end and the middle of the transverse bus bar 21 to the longitudinal bus bar 22, so that the unit input bar 2112 disposed at the middle of the transverse bus bar 21 can flow to the longitudinal bus bar 22 after flowing through the transverse bus bar 21 of 10cm, and the unit input bar 2112 disposed at the end of the transverse bus bar 21 can flow to the longitudinal bus bar 22 after flowing through the transverse bus bar 21 of 20 cm.
In practical applications, the longitudinal bus bar 22 may be electrically connected to the middle of the transverse bus bar 21, or may be electrically connected between the middle and any end of the transverse bus bar 21, so long as the longitudinal bus bar 22 is located between any two adjacent unit input bars 2112, the current of the unit input bars 2112 located on both sides of the longitudinal bus bar 22 is simultaneously conducted from the end of the transverse bus bar 21 to the longitudinal bus bar 22, so that the current path of the bus bar 100 may be shortened to reduce the electrical loss.
Further, in order to further shorten the current path of the bus bar 100, referring to fig. 1, in an embodiment of the bus bar 100 of the present utility model, the longitudinal bus bar 22 may be electrically connected to the transverse bus bar 21 that is spatially closest to the longitudinal bus bar 22. Thus, the current of the cell input bars 2112 located at both sides of the longitudinal bus bar 22 is simultaneously returned to the position of the lateral bus bar 21 closest to the longitudinal bus bar 22 in space to be converged to the longitudinal bus bar 22, so that the current path of the bus bar 100 can be further shortened.
Further, the longitudinal bus bar 22 may be electrically connected to the middle portion of the lateral bus bar 21, and the number of the unit input bars 2112 located at both sides of the longitudinal bus bar 22 is uniform, so that the current of the unit input bars 2112 located at both sides of the longitudinal bus bar 22 is simultaneously conducted to the middle portion of the lateral bus bar 21 to be conducted to the longitudinal bus bar 22, thereby ensuring that the current paths of the unit input bars 2112 located at both sides of the longitudinal bus bar 22 are uniform, so as to achieve the purpose of further shortening the current paths of the bus bar 100.
Further, referring to fig. 1 in combination, in an embodiment of the bus bar 100 of the present utility model, the transverse bus bar 21 includes two transverse units 211, each transverse unit 211 has at least one unit input row 2112, one end of one transverse unit 211 is connected to one end of another transverse unit 211, and the longitudinal bus bar 22 is connected in series at the connection of the two transverse units 211.
Because the length of the transverse bus bar 21 is long, if the transverse bus bar 21 is directly arranged into a whole complete structure, not only the packaging and the carrying are inconvenient, but also the risk of bending and even breaking easily occurs in the carrying process, so that in order to improve the problem, the transverse bus bar 21 is formed by splicing two transverse units 211 with short lengths.
Further, referring to fig. 2-6 in combination, in one embodiment of the bus bar 100 of the present utility model, the lateral unit 211 comprises at least two lateral rows 2111 disposed side by side, each lateral row 2111 having at least one unit input row 2112; the longitudinal buss bar 22 includes at least two longitudinal rows disposed side by side, each longitudinal row being connected in series with a transverse row 2111.
So configured, by having the lateral cells 211 include at least two lateral rows 2111 disposed side-by-side and having the longitudinal bus 22 include two longitudinal rows disposed side-by-side, so that different cell input rows 2112 may be bussed by different lateral rows 2111 and longitudinal rows, current flow between adjacent two cell input rows 2112 may be reduced.
Further, referring to fig. 1-3 in combination, in one embodiment of the bus bar 100 of the present utility model, the lateral units 211 are provided with insulating clips 212 such that the insulating clips 212 space adjacent lateral rows 2111 apart.
So configured, by spacing adjacent two lateral rows 2111 using the insulating clip 212 to avoid direct bonding between the adjacent two lateral rows 2111, the effective heat dissipation area of the lateral rows 2111 may be increased.
For example, the insulating clip 212 may have at least two slots 2121 disposed at intervals so as to clamp at least two lateral rows 2111 in the at least two slots 2121, respectively, that is, to support at least two lateral rows 2111 while spacing adjacent two lateral rows 2111.
Further, referring to fig. 6 in combination, in an embodiment of the bus bar 100 of the present utility model, a spacer 222 is disposed between two adjacent longitudinal rows, such that the spacer 222 separates the two adjacent longitudinal rows.
In this manner, the spacer 222 separates two adjacent longitudinal rows to avoid direct contact between the two adjacent longitudinal rows, thereby increasing the effective heat dissipation area of the longitudinal rows.
In practical applications, the isolation pad 222 may be a structural member made of silica gel pad, rubber pad, wood pad, etc.
Further, referring to fig. 7 in combination, in an embodiment of the bus 100 of the present utility model, the output interface 10 includes an output bus 11 and at least two connection buses 12, wherein one end of each connection bus 12 is connected to a bus bar 20, and the other end of each connection bus 12 is connected to the output bus 11.
By the arrangement, the current of at least two current collecting units can be collected to the output row 11 by using at least two connecting rows 12, so that a user can conveniently make a lap joint row design on the output row 11.
Illustratively, a surface of the output row 11 may serve as a landing surface for the output interface 10 to facilitate a user's lap design in the same plane, and the connecting row 12 may be disposed on a surface opposite the landing surface or adjacent the landing surface.
Further, referring to fig. 7 in combination, in one embodiment of the bus bar 100 of the present utility model, the connection bar 12 includes a first connection section 121 and a second connection section 122; the first connecting section 121 is connected with the bus branch 20 and is attached to the bus branch 20; the second connecting section 122 is disposed at an included angle with the first connecting section 121, and is connected to the output row 11, and is disposed in a fitting manner with the output row 11.
In this way, during the assembly process, the first connecting section 121 of the connecting bar 12 can be used to connect with the longitudinal bus bar 22 of the bus bar 20 in a bonding manner, so that the contact area between the first connecting section 121 and the longitudinal bus bar 22 can be increased, and the connection stability between the first connecting section 121 and the longitudinal bus bar 22 is improved; likewise, the second connection section 122 of the connection row 12 may be attached to the output row 11, so that the contact area between the second connection section 122 and the output row 11 may be increased, thereby improving the connection stability between the second connection section 122 and the output row 11.
Further, referring to fig. 1 in combination, in one embodiment of the bus 100, two adjacent lateral buses 21 are stepped. So set up, through carrying out reasonable design with two adjacent horizontal busbar 21, not only can avoid the electric current of two adjacent horizontal busbar 21 to influence each other, can also reduce the holistic occupation space of busbar 100, and then reduce the size of cabinet-type air conditioner.
Further, referring to fig. 1, 4 and 6 in combination, in an embodiment of the bus bar 100 of the present utility model, the bus bar 20 further includes an insulating support 23, and the longitudinal bus bar 22 is used for connecting to a cabinet through the insulating support 23.
So configured, the insulating support 23 is used to mount the longitudinal buss bar 22 to the cabinet during assembly, thereby supporting and securing the buss bar 100 to the cabinet.
The insulating support 23 may be screwed to the longitudinal bars 22, and may be screwed to the cabinet, for example.
And, each longitudinal busbar 22 can be connected to the cabinet by one or more insulating supports 23; for example, when the length of the longitudinal buss bar 22 is short, only one insulator may be used; when the length of the longitudinal buss bar 22 is long, two or more insulating supports 23 may be used, which may be specific to the actual use.
The utility model also provides a hydrogen production power supply product, which comprises a cabinet and the busbar 100, wherein the specific structure of the busbar 100 is shown in the previous embodiment.
