Problems solved by technology
[0004] However, for the power distribution unit of this structure, since the hydraulic switch cannot be directly connected to the user’s load cable, the cables in the output panel of the power distribution unit need to be transferred multiple times, and finally output through the DC output unit, that is, the hydraulic switch needs to be connected through a cable. The DC output terminal, and then the DC output terminal is connected to the user's load cable, the connection is more complicated, and the cable takes up more space

Embodiment Construction
[0035] In order to solve the problem in the prior art, because the hydraulic switch cannot be directly connected to the user's load cable, the cable in the output panel of the power distribution unit needs to be switched multiple times, and finally output through the DC output unit, that is, the hydraulic switch needs to be connected to the DC output terminal through the cable The DC output terminal connects the user’s load cable. The connection is more complicated and the cable takes up more space. The embodiment of the present invention provides a power distribution unit to save the space occupied by the cable and expand The number of output branches.
[0036] In order to make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments are given below to further describe the present invention in detail.
[0037] In the following specific embodiments, a 19-inch wide 1U high DC power distribution unit is taken as an example for explana...

The invention relates to the technical field of electricity, and discloses a power distribution unit and a communication power system. The power distribution unit and the communication power system are used for saving a space occupied by a cable and expanding the number of output branches. The power distribution unit comprises an input module and at least one output module, wherein the input module is connected with an external power supply, each output module is connected with the input module and is used for providing a voltage for external power utilization equipment, the input module is used for transmitting a voltage signal to each output module, each output module comprises a control switch and an output terminal which are integrated, and each control switch is used for controlling the voltage signal output from the corresponding output terminal. In the power distribution unit provided by the invention, the control switch and the output terminal are integrated to form a module, the length of a connection cable between the control switch and the output terminal is saved, meanwhile, the space where the cable is located can also be saved, and the number of the output branch is expanded.
Description
Technical field [0001] The present invention relates to the field of electrical technology, in particular to a power distribution unit and a communication power supply system. Background technique [0002] In the communication power system, using a smaller space to achieve larger output power and more output control terminals is the goal that the system layout is constantly pursuing, so that it can not only meet the needs of users to the greatest extent, but also occupy as little as possible System and computer room space. [0003] The DC power distribution of the 48V power supply system in the communication base station is generally equipped with a secondary DC power distribution unit. Its function is to distribute the DC power from the high-frequency switching power supply for the second time, and finally connect it to the final DC load (such as BBU, RRU, transmission and other communication equipment). The layout of the DC power distribution unit for communication power supply...
