Negative control terminal realizes also having the quantity of state acquisition function outside control and the management except realizing automatic collection, storage, teletransmission to ammeter datas such as user's electric energy meter electric weight, voltage, electric current, power and power factors to user's load.
Development and the professional quick application of distribution scheduling intensification along with distribution automation system; Negative control terminal is except the demand that satisfies sales service; Also want to guarantee dependent failure detection signal behind the power grid accident collection and on give, for the monitoring and the accident treatment of power distribution network provides safeguard.
Negative control terminal generally adopts ac power supply.As shown in Figure 1, the negative control terminal input directly connects the 220V ac output end of power distribution network.As if having an accident because of power distribution network or abnormal conditions occurring; Cause the negative control terminal power supply of losing the job; So, the switch position signal of power distribution network and fault detection signal when negative control terminal can't be gathered dead electricity also can't be with delivering to main website on these signals; Thereby can't let the real-time situation of recognizing power distribution network of distribution scheduling person, influence the efficient of accident treatment.
In the prior art, negative control terminal is except normal Alternating Current Power Supply, and what have has also designed reserve battery.But the power of reserve battery is little, is mainly used in work a period of times such as keeping host CPU, liquid crystal panel, fails to guarantee the power supply to the quantity of state acquisition module.Therefore, reserve battery also can't ensure information gathering and the transmission after negative control terminal has a power failure.
The utility model content
The utility model technical problem to be solved is: a kind of microminiature UPS device that ensures that negative control terminal power failure back information transmits is provided, solves the problem that can not realize information gathering after present negative control terminal has a power failure and be sent to main website.
The utility model technical problem to be solved realizes through following technical scheme: a kind of microminiature UPS device that ensures that negative control terminal power failure back information transmits is characterized in that: comprise the duplex feeding circuit of being made up of input unit, rectification unit, energy-storage units, switch unit, inversion unit and output unit;
One the tunnel is main power supply circuits: be in series successively by input unit, switch unit, output unit, another road is the stand-by power supply circuit: be in series successively by input unit, rectification unit, energy-storage units, switch unit, inversion unit and output unit;
Said switch unit is accomplished the switching between main power supply circuits and the stand-by power supply circuit.
Main power supply circuits: the alternating current of input unit input is directly outputed to output unit through switch unit; The stand-by power supply circuit: the alternating current of through rectification unit input unit being imported earlier converts direct current to and charges to energy-storage units; When switch unit switches to the stand-by power supply circuit, convert alternating current to and pass through output unit output through the direct current of inversion unit again energy-storage units output.
Said energy-storage units is recommended as farad capacitor, and discharge cycle is more than 5 minutes.
Described rectification unit is recommended as the AC/DC transducer that output voltage is 12V.
Beneficial effect: after being connected in the utility model between power distribution network and the negative control terminal; During the power distribution network operate as normal, power distribution network is directly to the negative control terminal power supply, and the energy-storage units charging of giving the microminiature UPS device of the utility model; After the unexpected decompression of power distribution network; Switch unit by the utility model automatically switches to by the stand-by power supply circuit supply, and keeps a period of time, makes negative control terminal can keep operating state a period of time; Thereby the position of the switch, fault detection signal and the various alarm signal of power distribution network are delivered to main website in time, and back distribution scheduling person carries out accurately, judgement provides decision-making foundation fast for power distribution network has an accident; The energy-storage units of the utility model adopts farad capacitor, and is not only simple in structure, and capacity is big, and charging rate is fast, and discharge cycle guarantees that negative control terminal has enough message processing times, thereby full detail is sent to main website more than 5 minutes.
