Device and method for AC/UPS mixed networking

Abstract

The invention provides an AC / UPS hybrid networking device and a method thereof. The device comprises: an AC distribution panel, a UPS connected with the AC distribution panel, and a control cabinet connected with the UPS and the AC distribution panel, wherein, the control cabinet comprises a comparative control circuit, a driving circuit and a high-speed silicon controlled static switch; the comparative control circuit sends a control instruction after comparing a received signal with a default reference signal; after receiving the control instruction, the driving circuit controls the high-speed silicon controlled static switch to strobe a corresponding current path which is directly connected with the AC distribution panel or connected with the UPS. Compared with the best technology of the normally used networking mode, the invention has the maximum benefit of reducing the average power consumption of more than 25 percent, also can basically avoid the harmonic interference and save the harmonic treatment expenses; as the hybrid networking equipment preferably selects AC as power, the dependence on the UPS is reduced, therefore, the quantity of the equipped UPS can be reduced, thus having the advantage of reducing the networking equipment investment.

Description

technical field [0001] The invention relates to a communication power supply networking device and its method, in particular to a UPS hybrid networking device and its method. Background technique [0002] At present, the networking methods of UPS power supply have the following general and common networking modes (hereinafter referred to as "general modes"), and these networking modes are widely representative: [0003] (1) 1 UPS power supply - 1 output; [0004] (2) 2 UPS parallel power supply - 1 output; [0005] (3) 2 sets of UPS in series for hot backup power supply - 1 output; [0006] (4) 2 UPS parallel hot backup power supply - 1 output; [0007] (5) 2 UPS combined (1+1) power supply - 2 outputs; [0008] (6) 3 UPS combination (2+1) power supply - 2 outputs; [0009] (7) 4 UPS combination (2+2) power supply - 2 outputs. [0010] The main purpose of the "general mode" is: 1. It can ensure that there is no need to switch the power supply during a power failure, so...

Problems solved by technology

According to the actual test results, the average loss of this "non-linear device" (at a load rate of 30%) accounts for 31% of the AC power supply, which obviously does not meet the requirements of the "energy saving and emission reduction" policy

[0012] In addition, due to the over-reliance on UPS in the "universal mode" on the network - trying to rely on UPS to undertake all security issues, while ignoring the substantive understanding of the internal power supply structure of power and communication equipment, the power resources cannot be reasonably allocated and utilized. As a result, such as "1", "2", "1+1", "2+1", "2+2" and other guarantee means that rely on simply expanding the scale of the network, the additional cost is extremely high. Moreover, once the UPS simultaneously If a fault occurs, the load cannot be switched to the mains power supply normally, which is the biggest risk of using the "universal mode"
