Description
Technical field
The utility model relates to a kind of power supply device, relates in particular to a kind of double loop power supply electric supply installation.
Background technology
In order to improve the responding ability of solution of emergent event, in buildings such as stadiums, subway, use double loop power supply, and generally take scheme as shown in Figure 2 to connect electric backward.Though use double loop power supply can improve the reliability of power supply, but still exist the power supply that causes owing to reasons such as power supply or device faults to lose, the situation that light fixture can not be lighted, such problem occurs and may cause big political fallout even entail dangers to people's life, the reliability that therefore how to improve power supply under the situation of having used double loop power supply to greatest extent is a very good problem to study.
In the engineering practice in the past, generally all is to consider a problem aspect the reliability that improves double loop power supply self, and to propose power supply I itself be that two-way electricity, power supply II adopt and in parallelly hold surplus or N+X module and hold surplus scheme the interruption of electric power is reduced to very little probability.Both just like this, in theory with practice in all exist when civil power is lost stand-by power supply cisco unity malfunction or interlock switch to break down and cause the light fixture quenching problem.
Summary of the invention
The purpose of this utility model is exactly in order to solve present double loop power supply low problem of reliability when important load is powered, provide a kind of have simple in structure, easy to use, the double loop power supply electric supply installation of power supply reliability advantages of higher.
For achieving the above object, the utility model adopts following technical scheme:

The utility model is according to the particularity of illumination, considers the reliability of powering from system-level, proposes a kind of scheme that supplies power with double circuit newly.The illumination that will be used in the same area in this scheme is divided into two-way, and the power of two road lighting lanterns can equate, also can set the minimum power on a certain road according to the requirement of brightness, then dump power is distributed to another road.This two road lighting lantern is connected with power supply II with power supply I by the switching device of interlocking respectively.Power all just often when the two-way power supply, the I that powers supplies with an output branch road 1 by interlock switch K1-1, and power supply II supplies with another by interlock switch K2-2 and exports branch road 2.When power supply I power down, interlock switch K1-2 closure, the II that will power supplies with output branch road 1; When power supply II power down, interlock switch K2-1 closure, the I that will power supplies with output branch road 2; Because the illumination that will be used in the same area is divided into two-way, and two-way output all can be by power supply I and power supply II power supply, has only when the two-way illumination just can cause the accident when all losing efficacy, and the probability that accident therefore occurs greatly reduces.The reliability of supposing duplex feeding and interlock switch device is 0.999, and promptly failure rate is 0.001, presses the scheme of Fig. 2, and the probability that light fixture extinguishes fully is 1-[1-(0.001)
2] * 0.999=0.001000999, the scheme of pressing Fig. 1, the probability that light fixture extinguishes fully is 1-[1-(0.001)
2] * [1-(0.001)
2]=0.000002, promptly using the utility model circuit the probability that light fixture extinguishes to occur is 2/1000ths of Fig. 1 scheme approximately, if light fixture is divided into N branch road and uses N interlock switch, the probability that light fixture extinguishes fully is 1-[1-(0.001)
2] * [1-(0.001)
N], failure rate can further reduce, but corresponding cost increases.
The utility model is because the equal bringing onto load of two-way power supply, and certain condition down can be intuitively and found the fault of two-way power supply timely.And if the means that Fig. 1 scheme there is no need are difficult to the fault directly perceived and power backup when the power supply of master's electricity of discovery timely.Be the utility model when directly improving power supply reliability owing to improved the promptness of finding fault simultaneously, therefore also indirect raising the reliability of power supply.
The beneficial effects of the utility model are: simple in structure, easy to use, stadiums, heavy construction, airport, subway, operating room etc. increase the reliability that has improved power supply under few prerequisite at cost, for example all can adopt this programme to the demanding occasion of throwing light on.
More than be to be that example illustrates the utility model with the lighting load.As long as the utility model all was suitable for when load can be divided into two-way at least and allow one the road to break down.
