Abstract
The utility model discloses a high frequency switch power supplying system, comprising a rectifier and a battery, wherein the rectifier converts the alternating current into direct current and divides the current into two paths for output, one path is directly output to a plurality of shunt load management units, the other path is output to a charging management unit, which is characterized in that: the charging management unit is also connected with a step-down circuit, and the voltage output from the charging management unit is transformed and output to a constant voltage protection circuit, the battery is charged on the real time by the constant voltage protection circuit and also connected with a discharge protection unit, the current discharged from the battery is protected on the real time by the discharge protection unit, and the discharge protection unit is connected with the shunt load management units. The high frequency switch power supplying system is simple in structure, convenient to manage, and avoids the whole system paralysis caused by excessive voltage.
Description
Technical field
The utility model relates to a kind of electric power system, is specifically related to a kind of high frequency switch power electric power system.
Background technology

Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of high frequency switch power electric power system, and this system configuration is simple, convenient management, can avoid because of excessive the caused whole system paralysis of voltage.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of high frequency switch power electric power system, this system comprises rectifier and battery, described rectifier converts alternating current to direct current and is divided into two-way output, several shunt loading administrative units are directly exported on one tunnel, another road is transported to the Charge Management unit, it is characterized in that: described Charge Management unit also is connected with reduction voltage circuit, and by this circuit, the voltage of Charge Management unit output is carried out being transported in the constant voltage protective circuit after transformation, by the constant voltage protective circuit, come in real time battery to be charged, described battery also is connected with the discharge prevention unit, and the electric current real-time guard of battery being put by the discharge prevention unit, described discharge prevention unit also is connected with the shunt loading administrative unit.
The beneficial effects of the utility model are: this system configuration is simple, convenient management, can avoid because of excessive the caused whole system paralysis of voltage.
The accompanying drawing explanation
Fig. 1 is the utility model system configuration schematic diagram.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of high frequency switch power electric power system, this system comprises rectifier and battery, rectifier converts alternating current to direct current and is divided into two-way output, several shunt loading administrative units are directly exported on one tunnel, another road is transported to the Charge Management unit, the Charge Management unit also is connected with reduction voltage circuit, and by this circuit, the voltage of Charge Management unit output is carried out being transported in the constant voltage protective circuit after transformation, by the constant voltage protective circuit, come in real time battery to be charged, battery also is connected with the discharge prevention unit, and the electric current real-time guard of battery being put by the discharge prevention unit, the discharge prevention unit also is connected with the shunt loading administrative unit.
When civil power work is arranged, rectifier utilizes the civil power alternating current 220V, be transformed into DC power supply output, on the one hand to shunt loading administrative unit supply current, provide charging by the Charge Management unit to battery on the other hand, the optional 12AH of battery capacity, 24AH, 38AH, 50AH, wherein the Charge Management unit is provided with reduction voltage circuit and constant voltage circuit, guarantees that battery can complete to fast and reliable charge function.
After mains failure, system can be powered to the shunt loading administrative unit by the discharge prevention unit is continual continuously by battery.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
