Specific embodiment
Below in conjunction with the attached drawing in the embodiment shown in the embodiment of the present application, to the embodiment shown in the embodiment of the present application
In technical solution be clearly and completely described.
Referring to Fig. 1, a kind of low voltage reactive power compensation cabinet, including exhaust fan room 1, cabinet body 2, supply fan room 3 and control
Device processed；It is provided with exhaust fan 101 in the exhaust fan room 1,2 side of cabinet body is provided with exhaust column 102, the exhaust column
102 one end are connected to the exhaust fan room 1, and 102 other end of exhaust column is connected to the cabinet body 2, the exhaust column 102
Exhausting air port 103 is formed with 2 place of being connected of cabinet body, is provided with temperature sensor at each exhausting air port 103
104；It is provided with breeze fan 301 in the supply fan room 3,2 other side of cabinet body is provided with air supply tube 302, it is described to send
One end of air hose 302 is connected to the breeze fan 301, and the other end of the air supply tube 302 is connected to the cabinet body 2, described
Air supply tube 302 forms air-supply air port 303 with 2 place of being connected of cabinet body, is provided with gear at each air-supply air port 303
Plate elevator 304；The controller is used to receive the temperature of the temperature sensor 104, and controls institute according to the size of temperature
State the aperture that baffle elevator 304 adjusts the air-supply air port 303.
It is arranged successively up and down therefore, because exhausting air port 103 is located at 2 side of cabinet body, the Low-voltage of the application is mended
Cabinet is repaid by the temperature at the detection of temperature sensor 104 exhausting air port 103, can be detected the temperature feelings in each region in cabinet body 2
Then condition controls the aperture that baffle elevator 304 adjusts air-supply air port 303 according to the size of temperature by controller, can allow temperature
Spend that the wind that high place is blown to is more more, the wind that the low place of temperature is blown to is few, thus accelerate the cooling to high-temperature area,
The control of temperature subregion is realized, energy conservation simultaneously can quickly cool down, to ensure equipment reliability of operation.
The exhausting air port 103 is identical as the air-supply quantity in air port 303, and the height in the exhausting air port 103 is high
Height in the corresponding air-supply air port 303.Since heat often moves upwards, thus it is described air-supply air port 303 in heat
It is big to measure the following wind speed in higher region, is conducive to blow away heat, exhausting air port 103 is facilitated to take out the hot-air after thermal convection
It walks, therefore, the low voltage reactive power compensation cabinet good cooling effect of the structure.
It includes: described for controlling the baffle elevator 304 to adjust the aperture in the air-supply air port 303 according to the size of temperature
Controller judges whether the temperature in each exhausting air port 103 is more than preset value, and the air-supply is kept if being not above preset value
The aperture in air port 303；If wherein having the temperature in exhausting air port 103 to be is more than preset value, the controller controls the exhausting wind
103 level heights of the mouth air-supply air port 303 below increases aperture, and it is horizontal high that the controller controls the exhausting air port 103
Du or more the air-supply air port 303 reduce aperture.
Since some air-supply air port 303 reduces aperture, in the case where total blast volume is constant, increase the air-supply of aperture
The air output in air port 303 can increase.Therefore, when some regions overheat, increase the aperture below superheat region, more greatly
Air quantity take away more heats, avoid partial region overheat, lead to equipment fault.Simultaneously by adjusting wind air port 303
Aperture does not need the power for increasing exhaust fan 101 and breeze fan 301, and fast cooling can be realized, therefore has energy saving, fast
The characteristics of cooling of speed, equipment reliability of operation is ensured.
The exhaust fan 101 is all made of variable-frequency motor driving with the breeze fan 301, when all exhausting air ports 103
When temperature is more than preset value, the controller increases speed for controlling the exhaust fan 101 with the breeze fan 301.
When the aperture by adjusting air-supply air port 303 is unable to reach the purpose of fast cooling, the application can also control the exhausting
The power of machine 101 and the breeze fan 301, the revolving speed raising for improving the exhaust fan 101 and the breeze fan 301 are sent
Wind energy power and exhausting ability achieve the purpose that realize fast cooling, improve equipment reliability of operation.
In conclusion the low voltage reactive power compensation cabinet of the application is simple, there is energy conservation, quickly cool down and set
The characteristics of high reliablity of received shipment row.
Those skilled in the art will readily occur to its of the application after considering specification and practicing application disclosed herein
