How to solve the problem of cabinets have a fever

; 1, debugging, of course, after high temperature alarm, yard to check on the ventilation cabinet/refrigeration/heat exchange system whether there is a fault.
;
the solution: replace the fan fault, check the cooling system of maintenance. MAO's dirty plugging flocculant can also cause abnormal refrigeration equipment work.
;
2, increase the power cabinet exhaust ability: some cabinets increases with load current, installed inside the cabinet or BBU or transmission devices, caused the increase of heat release, and cabinet cooling capacity cannot meet the requirements, produces the high temperature alarm. At this point by adding fan or air conditioning way to effectively relieve contained in the cabinet.
; High 0
the cabinet side. 3 - 0. 4 meters area opening, at the same time, equipped with insect nets and dust-proof net; Fan in the other side of the cabinet, fan it is recommended to use a dc 48 v power supply, under an electric position in electricity, and increase the temperature controller to control installed fan ( Can be installed in the 35 - 40 degrees) 。 In the external cover installation again. This method pay attention to the sealing, waterproof, and the late timing clean strainer.
;
to increase air conditioning: refers to the original power cupboard door to be modified, increase the ac/dc cooling air conditioning to achieve, a professional manufacturer in such technologies do, do not introduce here, interested can contact. ; ;
;
3, cabinet is prevented bask in: because of outside power supply tank wall thickness is thin, summer is the direct sun inside one of the main reasons of temperature rise. Sunscreen methods are varied.
paste: (1) reflective film surface on the wall outside the cabinet paste or tin foil reflective membrane, can effectively prevent the sun, cost effective, suggest cabinets of power supply cabinet walls thicker paste.
2) reflective heat insulation cotton installation: increase the reflective heat insulation cotton (on the outside of the cabinet Similar to the vehicle glass sun) , the effect is equivalent to paste the reflective film, but the middle layer of cotton wool or space, can have heat insulation effect.
3. Sun-shade net installation: sun-shade net install to adjust measures to local conditions, otherwise the wind sun-shade net impact is bigger, fixed also should pay attention to. Near the high voltage line installation is not recommended.
;
(4) equipped with sun protection cover: the way to the use of steel structure forming, aluminum-plastic plate fixed outside shading effect, retained for about 5 - in the middle 10 cm space, achieve the goal of heat insulation and ventilation. Late in the engineering installation when power cupboard door suggestion to north, can avoid the sun to be basked in eastern and western straight.
;
the above method not only can avoid device to heat up too fast, prolong the service life of battery, avoid switching power supply module and the circuit component failure happens because the temperature was too high, cause unnecessary network interruption, slow and device to heat up, also can effectively reduce the cooling fan operation time, have the effect of energy saving.
