Abstract

The utility model relates to an AC\DC dual power source switch-free device. The device is mainly composed of a 380V three-phase AC input end, a three-phase transformer, a three-phase full bridge rectifier, a 220V DC input end, a single-phase rectifier and an output end. The 380V three-phase AC input end is connected with the three-phase full bridge rectifier through the transformer. The 220V DC input end is connected with the single-phase rectifier. The three-phase full bridge rectifier and the single-phase rectifier are in parallel connection, and a parallel connection end is connected with the output end. Through the AC\DC dual power source switch-free device, dual input of a 380V alternating current and a 220V direct current can be realized to provide a safe, reliable and uninterrupted power source for equipment. Compared with a conventional AC\DC dual power source input device, the AC\DC dual power source switch-free device enables a superposed voltage value between the alternating current and the direct current after rectification of the alternating current to be effectively reduced and also enables the voltage pulsation amplitude after rectification of the alternating current to be effectively reduced, thereby mitigating aging losses of a line device and allowing output of the power source to be more stable.

Description

Hand over direct-current dual power exempt from switching device shifter
Technical field
The utility model relate to a kind of friendship direct-current dual power exempt from switching device shifter.
Background technology
The power supply of at present industrial automation control system use generally all requires safe and reliable, uninterrupted, mostly is the power supply of direct current 220V input, perhaps is the power supply of alternating current 220V and direct current 220V dual input, and power supply inside at first obtains pulsating direct current by single-phase rectification bridge.Yet, factories and miness consumer networks voltage is generally higher in actual applications, alternating current 220V generally can both reach 240V even higher, so that alternating voltage peak is also higher, especially adopt to hand in the direct current dual input, alternating current behind over commutation with direct current stack so that voltage is higher, long-play can cause then that the power supply internal calorific power is large, the device aging acceleration like this, even directly causes damage.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of friendship direct-current dual power exempt from switching device shifter, provide purpose safe and reliable, continual power supply to realize that 380V exchanges with the dual input of 220V direct current as industrial control equipment, thereby and this device with respect to existing hand over can effectively reduce the aging loss that slows down line device with the superimposed voltage value of direct current behind the AC rectification for the direct-current dual power input unit.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of friendship direct-current dual power exempt from switching device shifter, mainly consisted of by 380V three-phase alternating current input, three-phase transformer, three-phase full-bridge rectifier, 220V direct-flow input end, single-phase rectifier and output, 380V three-phase alternating current input is connected with three-phase full-bridge rectifier by transformer, the 220V direct-flow input end is connected with single-phase rectifier, three-phase full-bridge rectifier is in parallel with single-phase rectifier, and parallel connected end connects output.
The beneficial effects of the utility model are: by this friendship direct-current dual power exempt from switching device shifter and can realize that 380V exchanges with the dual input of 220V direct current and provide safe and reliable for equipment, the purpose of continual power supply, exchange with any one tunnel outage of direct current and can not cause voltage fluctuation, the three-phase alternating current phase shortage can not cause the output disappearance yet, and this device with respect to existing hand over can effectively reduce for the direct-current dual power input unit behind the AC rectification with the superimposed voltage value of direct current and exchanges mains ripple amplitude after rectification, thereby slow down the aging loss of line device and power supply exported more stable.This friendship direct-current dual power exempt from that switching device shifter is simple in structure, production cost is low.

The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is each components and parts syndeton schematic diagram of the present utility model.
Among the figure: 1.380V three-phase alternating current input 2. three-phase transformers 3. three-phase full-bridge rectifier 4.220V direct-flow input ends 5. single-phase rectifiers 6. outputs
Embodiment
A kind of friendship direct-current dual power exempt from switching device shifter, as shown in Figure 1, it mainly is made of 380V three-phase alternating current input 1, three-phase transformer 2, three-phase full-bridge rectifier 3,220V direct-flow input end 4, single-phase rectifier 5 and output 6,380V three-phase alternating current input 1 is connected with three-phase full-bridge rectifier 3 by transformer 2,220V direct-flow input end 4 is connected with single-phase rectifier 5, three-phase full-bridge rectifier 3 is in parallel with single-phase rectifier 5, and parallel connected end connects output 6.
