Description

Composite bus

Technical Field

Background

The terminal bus is a power distribution device of an electric terminal, which is generally composed of a copper conductor and an aluminum alloy shell, and realizes the function of supplying power to specific equipment through a device such as a plug box matched with the power distribution device. Especially, in a data center, a network cabinet power supply mode and a tail end bus power supply mode increasingly replace a traditional cable power supply mode of a column head cabinet, the power supply mode can provide larger power output capacity, has strong expansion capacity, saves precious space resources after replacing the column head cabinet, and enables users to more deploy the network cabinet. The tail end bus has the characteristics of series matching, commodity production, large capacity, short design and construction period, convenient assembly and disassembly, no combustion, safety, reliability and long service life. The end bus product is suitable for the power supply engineering of a three-phase four-wire and three-phase five-wire system data center network cabinet with 50Hz alternating current, 380V rated voltage and 250A-1000A rated current. The main design characteristics of the tail-end bus are plug-and-play, namely, the plug-in box matched with the bus is utilized to realize quick and convenient output, the design of the tail-end bus allows the plug-in box to be plugged in any position of the bus according to actual requirements to complete power output, meanwhile, the plug-in box also has the functions of monitoring electric energy and the like, and the electric energy service condition can be monitored in real time.

For a smart device such as a jack box, the supply of power and the connection to a network must be considered. There are two general ways of providing power: a bus electricity taking mode or an external power supply mode. The jack box itself has connected the generating line, and consequently the generating line is got the electric mode and is realized very easily, but the problem that this kind of mode brought is that the circuit of jack box can influence the test and the maintenance of generating line, if carry out the generating line and suppress the test, then must take off whole jack boxes and just can go on. Yet another way is to provide power externally, typically via a cable, to the jack box with a low voltage DC power supply (e.g., DC 24V). The communication connection of the jack box basically adopts RS485 network connection, and usually adopts shielded twisted-pair wires for cascade connection.
