Detailed Description
In order to solve among the prior art when empty allotment electricity cabinet breaks down, all air conditioners that can lead to being connected with the air conditioner switch board all have a power failure, have single-point trouble, seriously influence the problem of data computer lab normal operating, the utility model provides an empty allotment electric system of computer lab combines figure and embodiment below, and is right the utility model discloses further detailed description proceeds. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
The embodiment of the utility model provides an empty distribution of computer lab electricity system mainly includes M switch boards and a N terminal air conditioner, and the switch board mainly used carries out the distribution to the terminal air conditioner in the computer lab, is used for the cooling of computer lab behind the terminal air conditioner power supply, prevents that the equipment of placing in the computer lab from because the circuit short circuit appears in the high temperature or opens circuit, causes the condition appearance that equipment trouble burns even.
in this embodiment, set up M switch boards simultaneously in the computer lab, and M is for being greater than 1 integer, establish usually to 2 can, guarantee to have two switch boards to carry out the distribution work simultaneously at least in same computer lab promptly, even single point trouble has appeared in one of them certain, all the other switch boards still can continue to carry out the distribution work, guarantee the normal operating of computer lab air conditioner. It should be understood that, in this embodiment, each Power distribution cabinet in M Power distribution cabinets is a single-channel Power input, and its corresponding Power input can be mains input or Uninterruptible Power supply (UPS, universal Power System/universal Power supply), and it is different to best guarantee the Power input between two Power distribution cabinets or a plurality of Power distribution cabinets, so as to prevent that all Power distribution cabinets are all unusable because of outage or failure of the Power supply.
In this embodiment, the number of the end air conditioners is N, and N is an integer greater than or equal to 1. Under the general condition, because equipment such as broadband access server, large-scale switch constantly work in the computer lab, its inside temperature should not be too high, consequently need be through setting up terminal air conditioner in the computer lab in order to play the effect of cooling to, in order to reach better cooling effect, the quantity of terminal air conditioner should not set up too little, and the specific quantity that sets up should be confirmed according to the size of computer lab, the position of equipment in the computer lab and the power of air conditioner.
all install power switching device in every terminal air conditioner among N terminal air conditioners, terminal air conditioner passes through power switching device and is connected with arbitrary two switch boards among M switch boards, and the power input of a switch board is the commercial power among two switch boards of guaranteeing to connect better, and another is the input of uninterrupted power source, and under the circumstances of commercial power outage or uninterrupted power source trouble like this, terminal air conditioner still can normally supply power.
When the power distribution cabinet is in actual use, the tail end air conditioner is connected with the power supply through any one of the two power distribution cabinets which are communicated through the power supply switching device, the tail end air conditioner starts to work, and when a single-point fault occurs to the power distribution cabinet which is currently communicated with the tail end air conditioner, the power supply switching device switches the power supply of the tail end air conditioner to the output line of other power distribution cabinets through being connected to the current power distribution cabinet, so that the tail end air conditioner can be continuously supplied with power.
