Bus output unit

Abstract

The invention discloses a bus output unit. The bus output unit comprises an outer frame, a power supply access body, a pulling assisting device, an interlocking baffle, a surface cover, a cable, an outgoing line adjusting device, a plug, a main board, a low-voltage signal elastic sheet, a middle bracket, an air switch, a current transformer, a branch cable and an auxiliary board; the main board isembedded in the middle of the outer frame, the plug and the low-voltage signal elastic sheet are inserted into a plurality of jacks of the power supply access body from one side of the main board, and the temperature probe is arranged opposite to the plug; and an outgoing line adjusting device is arranged below the current transformer, and a pulling assisting device is arranged at the air switch.The plug of the output unit adopts a multi-point reed plug-in design to meet the requirements of large current and high reliability; the design of the interlocking baffle meets the phase-change output function, infrared temperature monitoring meets the temperature monitoring requirement, the adjustable wire outlet angle meets installation at various positions, the pulling assisting mechanism meets the single-hand plugging operation, and the various design meets the requirements for small occupied space, safety, reliability and easiness in use at the same time.

Description

technical field [0001] The invention relates to power distribution technology, in particular to a bus output unit. Background technique [0002] The terminal bus bar is usually a terminal power distribution device composed of copper conductors and aluminum alloy shells. Through the matching plug-in boxes and other devices, it can realize the function of supplying power to specific equipment. Especially in the power supply of the network cabinet in the data center, the power supply mode of the terminal bus has increasingly replaced the traditional cable power supply mode of the head cabinet. This power supply mode can provide a large power output capability and has a strong expansion capacity, and at the same time, it saves precious space resources after replacing the top cabinets, enabling users to deploy more network cabinets. The terminal busbar is characterized by series matching, commercial production, large capacity, short design and construction period, convenient ass...

Problems solved by technology

First of all, the current installation density of servers and network equipment is getting higher and higher, and the power demand is increasing, so the rated current requirement of the terminal busbar is also higher, such as 1000A; while the current terminal busbar products usually have a rated current of 400A, a certain Some manufacturers can reach 630A after improvement; the main design difficulty of the terminal bus bar with high current is: 1. The electromotive force at high current usually causes the magnetic oscillation frequency to form a superposition state, resulting in excessive noise; 2. The high current will cause High heat generation, the terminal busbar is usually installed in the data room, and the temperature rise requirement is higher than that of the usual dense busbar, so good heat dissipation is required

Secondly, the installation of the terminal bus takes up the space on the top of the network cabinet, which usually requires an installation clearance of 800mm or higher. At the same time, the conventional design of the dual bus makes the installation space narrower, especially for some data centers with low building heights. , conventional terminal busbars may not be installed at all, which greatly limits the popularity of terminal busbars
