Various in order to solve the equipment that exists in the prior art, it is big to take up room, functions of the equipments are single, problems such as operation inconvenience, the utility model proposes a kind of communication power supply screen, it is made up of duplicate supply switch unit, rectification unit, isolating transformer, and the duplicate supply switch unit is connected with rectification unit by isolating transformer, and rectification unit is connected with output; Duplicate supply switch unit, rectification unit, isolating transformer, battery unit (storage battery) are arranged in the same screen.
The duplicate supply switch unit comprises that I road and II road two-way power supply and two-way haul oneself willingly into equipment, and the I road is hauled oneself willingly into equipment with II road two-way power supply by two-way and is connected with isolating transformer, wherein another road power supply of locking during one road power work.
The former limit and the secondary of isolating transformer respectively are provided with a lightning protection device.
Also be connected with controller and storage battery on the rectification unit respectively, connect by under-voltage plate between controller and the storage battery, under-voltage plate is connected with output, and accumulator property is monitored control.
Rectification unit is made up of two identical high frequency switching rectifier modules, two high frequency switching rectifier module load-sharings, stand-by heats each other; Two high frequency switching rectifier modules all are connected with controller.
Useful technique effect of the present utility model is: the unit of multiple function is incorporated in the one side screen, has saved the space, is convenient to operation and management; The duplicate supply input can not cut off the power supply under the situation that one road power supply damages in rapid switching; Be provided with standby battery,, can under the primary source failure situation, do not cut off the power supply automatically to charge in batteries.
Description of drawings
Fig. 1, duplicate supply switch unit are connected block diagram with device between the output;
Fig. 2, duplicate supply switch unit are connected block diagram with device between the rectification unit;
The exemplary circuit of the circuit between Fig. 3, rectification unit of the present utility model and the output.
Embodiment
Referring to Fig. 1, the utility model structure is made up of duplicate supply switch unit 1, rectification unit 3, isolating transformer 4, duplicate supply switch unit 1 is connected with rectification unit 3 by isolating transformer 4 that (isolating transformer 4 has been isolated the direct electrical link of duplicate supply switch unit 1 and rectification unit 3, big electric current enters the other end when preventing equipment wherein an end received thunderbolt), rectification unit 3 is connected with output 7; Duplicate supply switch unit 1, rectification unit 3, isolating transformer 4 are arranged in the same screen.
Duplicate supply switch unit 1 comprises that I road and II road two-way power supply and two-way haul oneself willingly into equipment 1-1, and the I road is hauled oneself willingly into equipment 1-1 with II road two-way power supply by two-way and is connected with isolating transformer 4, wherein another road power supply of locking during one road power work.When one road power failure wherein, haul oneself willingly into equipment 3 by two-way and can automatically switch to another road power supply, and, improved the reliability of system the trouble power locking.
The former limit of isolating transformer 4 and secondary respectively are provided with a lightning protection device 10.
Also be connected with controller 5 and storage battery 6 on the rectification unit 3 respectively, connect by under-voltage plate 8 between controller 5 and the storage battery 6, under-voltage plate 8 is connected with output 7.Under-voltage plate 8 detects whether under voltage and signal is sent to controller 5,6 chargings of 3 pairs of storage batterys of controller 5 control rectification units of storage battery 6.After the two-way power supply of duplicate supply switch unit 1 all lost efficacy, the under-voltage plate 8 of controller 5 controls switched to storage battery 6 power supplies.
