The communication power device of the utility model adopts the generating line structure of non prismatic according to the characteristic of gradual increase or reduction of the generating line current, which reduces the copper material consumption and effectively reduces the cost of the confluence system and the power device under the precondition of satisfying the function of the system.
Description
[technical field]
The utility model relates to communication power supply equipment, relates in particular to a kind of communication power supply device with bus.
[background technology]
Power-supply system is the important component part that any communication system is rely and normally moved.In the power supply system for communications, no matter low-voltage alternating-current power distribution cabinet or the present applied bus structure of DC power cabinet are uiform section formula structure.In DC power cabinet, each rectification module is flowed to uiform section by cable and confluxes on the busbar, is diverted to distribution system again; In the low-voltage alternating-current power distribution cabinet, the alternating current of input is distributed to a plurality of rectifiers by bus.Because the electric current that flows through of busbar each several part is unequal, this kind uiform section bus structure exists the consumption of problem, particularly copper material of material serious waste too much, uneconomical, has increased the input of subscriber equipment cost.
[summary of the invention]
It is less that the technical problems to be solved in the utility model provides a kind of bus consumption copper material, can reduce the communication power supply device of equipment cost.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of communication power supply device, comprise bus, comprise on the every bus and have 2 branch road binding posts at least, the cross section of bus varies along its length, the area of bus cross section near power supply input or output end place maximum, inputing or outputing end place minimum away from power supply.
Above-described communication power supply device, described bus are preferably the stepped construction that the different thin layer copper bar of length is formed.
Above-described communication power supply device, described communication power supply device can be a DC power cabinet, and the above branch road binding post of bus connects rectifier by cable, and the big end of bus is an output.
Above-described communication power supply device, described communication power supply device also can be the communication power supply devices that is at least 2 DC power cabinet parallel operation, and described bus is the parallel operation bus of DC power cabinet; Described branch road binding post connects the bus rod of DC power cabinet inside, and the big end of described parallel operation bus is an output.
More than 2 described communication power supply devices, described communication power supply device can also be the low-voltage alternating-current power distribution cabinet, the big end of bus is by the switch external AC power supply, described branch road binding post connects load by switch.。
The characteristic that the utility model communication power supply device progressively increases or progressively reduces according to bus current, taked the bus structure of variable cross-section, reduce the consumption of copper material, under the prerequisite of the function needs that satisfy system, reduced the cost of conflux system and supply unit effectively.

Fig. 3 is the schematic top plan view under 2,6 DC power cabinet parallel operation of the utility model communication power supply device embodiment state.
Fig. 4 is the bus structure schematic diagram of the utility model communication power supply device embodiment 3 low-voltage alternating-current power distribution cabinets.
[embodiment]
Shown in Figure 1 is the bus structure of the utility model communication power supply device embodiment 1 DC power cabinet.DC power cabinet comprises 2 groups of busbars that conflux (bus), every group of group conflux busbar comprise all have many to anode and cathode terminals.The rectifier output current is pooled to positive pole busbar (bus) 5 and the negative pole busbar (bus) 6 that confluxes that confluxes by positive terminal 1, negative terminal 2, electrode cable 3 and negative pole cable 4 respectively with blocks current at different levels, through upper positive bus-bar 7 and negative bus-bar 8 electric current is pooled to positive and negative parallel operation busbar 10 and 9 again, is transported to the distribution that distribution system is carried out electric current then.The busbar 5,6,7,8 that confluxes is stacked variable section structure, and by many thin layer copper bars that length is different, the assembly that superposes forms according to the characteristic of confluxing of system, and the cross section of bus varies along its length.The conflux top of busbar 5,6 is the output of power supply, and the electric current maximum that flows through is so the cross section of busbar is maximum herein; Conflux the lower end of busbar 5,6 away from the output of power supply, and the electric current minimum that flows through is so the cross section of busbar also is minimum herein.Conflux busbar by the supporting of insulating reliably of insulation systems such as supporting traverse 12 and insulator 11, the reliability service of the system that guaranteed to conflux.
The communication power supply device of Fig. 2 and the utility model embodiment 2 shown in Figure 3 by 101 to 106 totally 6 DC power cabinet parallel operation form.The positive and negative parallel operation bus 10 of 101 to 103 3 DC power cabinet and 9 parallel operation bus 10a, 10b, 10c and 9a, 9b, 9c by each DC power cabinet form.All be that the assembly that superposes forms according to the characteristic of confluxing of system by the thin layer copper bar. Parallel operation bus 10a, 10b, 10c and 9a, the 9b of each DC power cabinet, 9c pass through the bus rod that separately binding post connects each DC power cabinet inside respectively.Because the parallel operation bus 10c of DC power cabinet 103 and 9c have compiled the output current of 101 to 103 3 DC power cabinet, so its cross section maximum near the output of supply unit.And the parallel operation bus 10a of DC power cabinet 101 and 9a only carry the output current of this machine, and its cross section is minimum.
Fig. 4 has shown the bus structure of the utility model communication power supply device embodiment 3 three-phase low-voltage alternating-current power distribution cabinets.3 buses 11 of low-voltage alternating-current power distribution cabinet are respectively by many thin layer copper bars that length is different, and the assembly that superposes forms according to the characteristic of confluxing of system, and the big end on its top is by input air switch 12 external AC power supplies, input current.Bus 11 connects the load output current respectively by a plurality of binding posts 13, cable 14 and branch air switch 15 from top to bottom.Because bus 11 electric current from top to bottom successively decreases, so the area of its cross section also successively decreases the cross-sectional area minimum of bottom.
The characteristic that the utility model communication power supply device progressively increases or progressively reduces according to bus current, taked the bus structure of variable cross-section, reduce the consumption of copper material, under the prerequisite of the function needs that satisfy system, reduced the cost of conflux system and supply unit effectively.
