Description
Technical field:
The present invention relates to a kind of farad capacitor charge and discharge protector in parallel, belong to security appliance field.
Background technology:
Currently, farad capacitor is long because of its life-span, safety of charging, and capacity is big, day by day paid attention to, but, farad capacitor because of in its production process, the many factors such as concordance and use condition, when multiple parallel connection, it may appear that the phenomenons such as self discharge increase, and cause there is potential safety hazard.
Summary of the invention:
The present invention relates to a kind of farad capacitor charge and discharge protector in parallel, to realize the purpose to farad capacitor protection in parallel.
For realizing above-mentioned purpose, the present invention adopts the following technical scheme that
A kind of farad capacitor charge and discharge protector in parallel, comprises:
Farad capacitor (1), power supply ground (2), output protection diode (3), power output terminal (4), input protection resistor (5), short circuit insurance (6), input protection diode (7), power input terminal (8)；As shown in Figure 1.
nullBelow in conjunction with accompanying drawing，Technical construction and the method for the present invention are described: multiple farad capacitors (1) also connect in circuit，The output on each road farad capacitor (1) is connected to output protection diode (3)，It is finally output on power output terminal (4)，Input in farad capacitor (1)，The input of each farad capacitor (1) is connected to input protection resistor (5)、Short circuit insurance (6) and input protection diode (7)，Finally it is all connected to power input terminal (8)，All farad capacitors (1) negative pole with connecing power supply (2)，When farad capacitor is charged，The situations such as short circuit occur such as farad capacitor，Then short circuit insurance (6) fusing，Thus protecting other farad capacitor (1) unaffected，Simultaneously，Because being filled with electricity to use diode-isolated，Make there is no mutual charge and discharge phenomena between farad capacitor (1)，Protect farad capacitor (1) equally，Improve efficiency in parallel.
Beneficial effects of the present invention: protecting safe and reliable, circuit is simple.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention.
Detailed description of the invention:
In order to make technical scheme clearly understand, below in conjunction with drawings and Examples, the present invention is described in more detail, instantiation described herein, only in order to explain the present invention, is not limited to the present invention.
Embodiment:
nullRefer to shown in accompanying drawing 1，Multiple farad capacitors (1) also connect in circuit，The output on each road farad capacitor (1) is connected to output protection diode (3)，It is finally output on power output terminal (4)，Input in farad capacitor (1)，The input of each farad capacitor (1) is connected to input protection resistor (5)、Short circuit insurance (6) and input protection diode (7)，Finally it is all connected to power input terminal (8)，All farad capacitors (1) negative pole with connecing power supply (2)，When farad capacitor is charged，The situations such as short circuit occur such as farad capacitor，Then short circuit insurance (6) fusing，Thus protecting other farad capacitor (1) unaffected，Simultaneously，Because being filled with electricity to use diode-isolated，Make there is no mutual charge and discharge phenomena between farad capacitor (1)，Protect farad capacitor (1) equally，Improve efficiency in parallel.
