Embodiment
By reference to the accompanying drawings embodiment of the present utility model is described further:
For a uninterrupted power supply device for network base station, comprise mains-supplied circuit and uninterrupted power supply supply line.As shown in Figure 1, mains-supplied circuit and uninterrupted power supply supply line compose in parallel uninterrupted power supply device, and the input of uninterrupted power supply device connects mains electricity input end, and the output of uninterrupted power supply device is by relay responding to switch interconnection network base station.Mains electricity input end is connected with the detection control circuit for detecting mains-supplied line current and information of voltage, described detection control circuit communication control relay.
Uninterrupted power supply supply line comprises rectification circuit, storage battery and inverter circuit, the input of described rectification circuit connects mains electricity input end, the output of rectification circuit connects storage battery, and also there is charge cutoff circuit at storage battery two ends, and storage battery connects relay responding to switch by inverter circuit.As shown in Figure 2, civil power passes through transformer 1 transformation to charge cutoff circuit, by rectifier bridge 2 rectification, electric capacity C1 filtering becomes direct current.LED1 is power supply indicator, and LED2 is charging indicator light, and T1 controls triode for charging, works on off state, and T2, T3 and electric capacity C2 form monostable trigger, and R6, RP form pressure limiting sampling slip, and R7 is current limliting sample resistance.Switch on power, if do not connect battery, triode T2 is because ending without base voltage, and triode T1 also ends, Non voltage output.Now only have power supply indicator LED1 luminous.
Charging process: after correctly connecting rechargeable battery, triode T2 slight conducting because of electricity more than battery, its collector potential declines, the rapid conducting of T1, and output voltage raises; Because C2 is positive feedback effect, circuit state reaches stable state rapidly.Now, T1, T2 conducting, T3 ends, and charges the battery, and charging indicator light LED2 is luminous.In charging process, monostable trigger plays the effect of restriction charging current.Until battery close to when being full of, diode D1 conducting, T3 is conducting also, and T1, T2 end, and have turned off charging circuit passband, complete charge.Storage battery is full of electricity, and when uninterrupted power supply supply line does not work, this circuit is in off-state, adds the security performance of uninterrupted power supply device.
As shown in Figure 3, detection control circuit comprises voltage transformer for detecting mains-supplied line voltage distribution, for detecting current transformer and the controller of mains-supplied line current, voltage transformer and current transformer are by analog to digital converter connection control device, the output of controller connects relay, and Control is communicated with relay responding to switch.Analog to digital converter is double-channel analog/digital transducer.
Voltage transformer and current transformer detect the quality of power supply of mains electricity input end in real time.Controller receives electric current, the voltage data of the input of analog to digital converter, judges whether mains-supplied circuit exists the phenomenons such as voltage fluctuation, frequency fluctuation, wave distortion or instantaneous power-off.If there is appeal phenomenon, control relay action, relay responding to switch and uninterrupted power supply supply line connect, storage battery by inverter circuit for network base station provides the alternating current of voltage stabilization.After controller judges that above-mentioned phenomenon disappears, control relay action, relay responding to switch is communicated with mains-supplied circuit.Storage battery starts charging, and electricity is full of rear charge cutoff circuit operation, automatically disconnects.
Certainly; more than illustrate and be only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the guidance of this specification; made all equivalently to substitute, obvious variant, within the essential scope all dropping on this specification, protection of the present utility model ought to be subject to.
