Description

Voltage controls protector
Technical field
This utility model is related to a kind of voltage and controls protector, and particularly relating to can overvoltage shape in protection circuit system simultaneously The voltage of state and under-voltage state controls protector.
Background technology
The overvoltage of Circuits System or under-voltage all can produce to load and destroy, and therefore has many for mistake in Circuits System Voltage or the design protection of under-voltage.
Such as TaiWan, China the I535165th discloses " power supply device of tool overvoltage protection ", and this case is using benefit Repay unit and carry out drive control device, to control DC/DC power converter, it is to avoid the electricity of DC/DC power converter output The magnitude of voltage of power constantly rises, to reach the effect of overvoltage protection.
TaiWan, China the I354423rd discloses " less voltage protector ", and this case receives the input voltage outside, and And match with a fan, this less voltage protector includes a voltage detection unit and a start unit.Wherein, this voltage Detector unit receives this input voltage, and this start unit is electrically connected with this voltage detection unit and this fan, and according to this input This fan of voltage starting, when this input voltage is less than a reference voltage, this voltage detection unit closes this start unit.
But, above-mentioned front case simultaneously cannot protect the state of overvoltage and under-voltage simultaneously.
Utility model content
In order to solve the above problems, this utility model provides a kind of voltage and controls protector, can protection circuit system simultaneously The state of overvoltage and under-voltage in system.
This utility model includes:
One circuit board;One processing unit, setting is on the board;One voltmeter, setting is on the board and electrical Connect this processing unit;One circuit control module, setting on the board and is electrically connected with this processing unit;One overvoltage is protected Shield switch, setting on the board and is electrically connected with this processing unit;One low-voltage protection switch, setting is on the board And it is electrically connected with this processing unit;One alarm unit, setting on the board and is electrically connected with this processing unit.
Further, this alarm unit includes loudspeaker.
Further, this alarm unit includes a luminescence component.
Further, this voltmeter is mechanical type voltmeter or electronic type voltage table.
Following effect can be produced by above-mentioned technical characteristic:
Using this over-voltage protection switch and this low-voltage protection switch, this utility model can be simultaneously in protection circuit system Overvoltage and the state of under-voltage.
Brief description
Fig. 1 is device configuration figure of the present utility model;
Fig. 2 is functional block diagram of the present utility model;
Fig. 3 is implemented on the schematic diagram of Circuits System () for this utility model;
Fig. 4 is implemented on the schematic diagram of Circuits System (two) for this utility model.

Specific embodiment
Summary technical characteristic, the primary efficacy of the voltage control protector that this utility model provides can be in following realities Apply example to clearly appear from.
As shown in Figures 1 and 2, the present embodiment includes:
One circuit board 1;One processing unit 2, is arranged on this circuit board 1;One voltmeter 3, is arranged on this circuit board 1 simultaneously It is electrically connected with this processing unit 2, this voltmeter 3 can be mechanical type voltmeter or electronic type voltage table;One circuit control module 4, It is arranged on this circuit board 1 and is electrically connected with this processing unit 2;One over-voltage protection switch 5, is arranged on this circuit board 1 simultaneously It is electrically connected with this processing unit 2;One low-voltage protection switch 6, is arranged on this circuit board 1 and is electrically connected with this processing unit 2; One alarm unit 7, is arranged on this circuit board 1 and is electrically connected with this processing unit 2, and in the present embodiment, this alarm unit 7 includes One loudspeaker 71 and a luminescence component 72.Further it is noted that this over-voltage protection switch 5 and this low-voltage protection switch 6 Same assembly can be integrated into or be provided separately, depending on use demand.
As shown in Fig. 1 and Fig. 3, Fig. 4, this utility model is connected in a Circuits System, this Circuits System is wrapped further Include a power supply 8 and a load 9, during this load 9 work, can directly be read the magnitude of voltage in this Circuits System by this voltmeter 3, and This magnitude of voltage is inputted to this processing unit 2, to judge this load 9 whether normal work.Magnitude of voltage in this Circuits System When too high, this processing unit 2 will control this over-voltage protection switch 5 to disconnect, and makes this Circuits System form open circuit;When this circuit system When magnitude of voltage in system is too low, this processing unit 2 will control this low-voltage protection switch 6 disconnection, so that this Circuits System is formed disconnected Road;To protect this load 9, it is to avoid this load 9 is because the overvoltage condition in this Circuits System or under-voltage state cause to damage.
And, when this over-voltage protection switch 5 disconnects or this low-voltage protection switch 6 disconnects, this processing unit 2 controls This loudspeaker 71 sends the different sounds according to overvoltage condition or under-voltage state, and controls this luminescence component 72 according to overvoltage State or under-voltage state produce different light-emitting modes, use and notify user to come to exclude abnormality.And work as abnormality row After removing, this over-voltage protection switch 5 and this low-voltage protection switch 6 can be resetted in the way of using hand-reset by user, This load 9 is made to rework.
The explanation of summary embodiment, produces when being fully understood by operation of the present utility model, use and this utility model Raw effect, but embodiment described above is only preferred embodiment of the present utility model, new when this practicality being limited with this Type implement scope, that is, according to this utility model right and utility model description made simple equivalence changes and Modify, all belong in the range of this utility model covers.
