During present invention work, coordinate the cable shaft of bottom by cabinet inner blower and air channel blower fan, so that cold air enters casing out of cable shaft, while two fans in series cooperatively form 2 times of blast, to overcome roof and Turbulent Flow Type hot-air to the resistance produced by the exhaust vent air draft of roof surrounding bottom.Compared with prior art, the beneficial effects of the present invention are the present invention strengthens the heat dispersion of inverter cabinet, it is ensured that transformer station runs reliably and with long-term by being equipped with independent exhaust system to inverter cabinet.The present invention can be used for block supply place.
In order to further enhance the radiating effect of air channel blower fan, the air channel blower fan is obliquely installed towards casing outside, and is 45 ° with horizontal direction angle.
32 mesh stainless steel filter screens are provided with order to which the water resistance and guarantee that strengthen casing can effectively filter out to be provided with the outside of the impurity in air, the air inlet on the inside of shutter, air inlet.
In order to strengthen the water resistance of casing and strengthen the heat dispersion in casing, it is provided with the outside of the air outlet on the inside of shutter, air outlet and is provided with axial flow blower.
In order to strengthen the heat-proof quality of casing and ensure the thermal diffusivity of casing, the top cover includes connection and is encapsulated in the bottom plate of casing top and the side plate of herringbone top plate, the bottom plate is thermal insulation board, the through hole connected with wind output channel is offered on bottom plate, the top plate includes being encapsulated in warming plate upper strata flashing board, and the exhaust vent is opened in side plate bottom.
32 mesh stainless steel dedusting nets are provided with the impurity of bottom cold air, the air vent in order to effectively filter out.
In order to ensure that the temperature of cold air in cable shaft remains at low levels, so as to strengthen inverter cabinet heat dispersion, the depth of the cable shaft is more than or equal to 1.2 meters.
