Abstract
The utility model discloses a special fan controller used for a capacitor compensation cabinet of a circulating switch mode. The special fan controller comprises a central processing unit, a detection circuit, a power module, a man-machine interchange module and a fan drive circuit, wherein the power module is used for providing a power supply for the central processing unit; the man-machine interchange module is used for setting a preset value of the quantity of input capacitors for the central processing unit; the detection circuit is used for monitoring the capacitors; after the capacitor controller is started, the central processing unit is used for regulating the working state of the fan drive circuit according to capacitor input quantity information acquired by the detection circuit; if the capacitor input quantity exceeds a preset value, a fan is started by the central processing unit through the fan drive circuit; and if the capacitor input quantity is lower than the preset value, the fan is closed by the central processing unit through the fan drive circuit. The fan can be controlled by the controller disclosed by the utility model according to the capacitor input quantity.
Description
Technical field
The utility model belongs to the low-voltage distribution technical field, relates to especially a kind of special fan controller of the capacitor compensation cabinet for the switching cycle mode.
Background technique
In the low-voltage distribution system, comprise a kind of mode of switching cycle in the switching mode of capacitor compensation cabinet.Compare other switching modes, the advantage of switching cycle mode is: in the long-time running of capacitor compensation cabinet, the switching frequency of each capacitor is identical, thereby can use more equably capacitor.Because capacitor compensation cabinet can produce certain heat when operation, dispelled the heat therefore when capacitor drops into above some, need to start blower fan in addition.And capacitor compensation cabinet automatic compensating controller in the market can not calculate the capacitor input quantity when adopting the switching cycle mode, therefore the switching cycle mode is difficult to the blower fan in the cabinet is controlled.
The model utility content
For addressing the above problem, the purpose of this utility model is to provide a kind of special fan controller of the capacitor compensation cabinet for the switching cycle mode, when being used for adopting the switching cycle mode, controller can be according to the input quantity of capacitor, blower fan is controlled, solved the problem that switching cycle mode capacitor compensation cabinet is difficult to control blower fan.
For achieving the above object, the technical solution of the utility model is:
A kind of special fan controller of the capacitor compensation cabinet for the switching cycle mode, comprise central processing unit, testing circuit, power module, human-computer interaction module and blower fan drive circuit, described power module is used for providing power supply to described central processing unit, described human-computer interaction module is used for setting to described centre unit the preset value of described capacitor input quantity, described testing circuit is used for monitoring capacitor, after the controller of capacitor starts, the working state that described central processing unit is regulated described blower fan drive circuit for the capacitor input quantity information of obtaining according to testing circuit
If described capacitor input quantity surpasses preset value, central processing unit starts blower fan by the blower fan drive circuit,
If described capacitor input quantity is lower than preset value, central processing unit is closed blower fan by the blower fan drive circuit.
Compared with prior art, the utility model can be preset and detect the capacitor input quantity of switching cycle mode, and then according to the relatively startup of testing result and predefined value with close blower fan, solved the problem that switching cycle mode capacitor compensation cabinet is difficult to control blower fan.
Description of drawings
Fig. 1 is the structured flowchart of special fan controller of capacitor compensation cabinet of the utility model embodiment's the switching cycle mode that is used for.
