Embodiment
Below in conjunction with accompanying drawing, to above-mentioned being clearly and completely described with other technical characteristic and advantage of the present invention, obviously, described embodiment is only section Example of the present invention, instead of whole embodiment.
Refer to shown in Fig. 1, a kind of outdoor frequency conversion tank comprises cabinet 1 for placing frequency converter and cabinet door 10, and cabinet door 10 is sealed on the sidewall opening of cabinet 1.In the present embodiment, cabinet 1 and cabinet door 10 are assembled into a cube, cabinet door 10 is one of them sidewall that can open or close cubical, cabinet 1 is for be made up of steel plate, the junction sealing of each steel plate, the surrounding of cabinet door 10 has installed sealing joint strip, and close Over-The-Counter door 10, frequency conversion tank becomes a closed structure.
The sidewall of cabinet 1 is oppositely arranged air inlet and air outlet, at the arranged outside air inlet protective cover 9 of air inlet, at the arranged outside air outlet protection cover 2 of air outlet, air inlet protective cover 9 and air outlet protection cover 2 can prevent sleet from entering in cabinet 1.The bottom of air inlet protective cover 9 and the bottom of air outlet protection cover 2 arrange ventilating opening respectively, and one piece of baffle plate is respectively installed at ventilating opening place, can effectively be dispelled the heat by ventilating opening, use baffle plate that foreign matter can be avoided to be entered in cabinet 1 by ventilating opening simultaneously.
In the present embodiment, the edge of entrance hole 7 and wire hole 8 is provided with protection cushion rubber, cable to penetrate in cabinet 1 and installs, and with fire-proof and explosion-proof clay, shutoff is carried out in entrance hole 7, gap between wire hole 8 and cable, such frequency conversion tank forms completely airtight space.Cabinet 1 top arranges four hoisting rings 6 being convenient to install or transport.
Outdoor frequency conversion tank of the present invention can be dispelled the heat by ventilating opening effectively when the internal temperature of cabinet 1 raises, and prevents the electric elements in cabinet 1 from causing damage due to high temperature; The present invention can also, when raining or winter snows, prevent sleet from entering in cabinet 1 by air inlet protective cover 9 and air outlet protection cover 2, once short circuit, the earth fault of electric elements can occur for rainwater or snow melting.The present invention can eliminate and cause damage because internal temperature raises, and improves the useful life of outdoor frequency conversion tank, prevents sleet from invading and causes electric elements short circuit, earth fault, guarantee the safe operation of outdoor frequency conversion tank.
Further, baffle plate is mesh type baffle plate 4 or closed type baffle plate 5.According to the change of external environment condition during Various Seasonal, dissimilar baffle plate is installed.Generally install mesh type baffle plate 4, mesh type baffle plate 4 has the function of ventilating and preventing the foreign matters such as toy from entering.Particularly have winter comparatively driving snow time, closed type baffle plate 5 without mesh is installed, the ventilating opening at air inlet and air outlet place is all closed, wind and snow can not blow in cabinet 1, and winter, outside air temperature was usually all in subzero, the internal temperature of cabinet 1 also can not be made too high by the complete totally enclosed frequency conversion tank of closed type baffle plate 5.
As the enforceable mode of one, the top of air inlet protective cover 9 and the top of air outlet protection cover 2 all arrange inclined plane, and the angle between inclined plane and level ground is more than or equal to 15 degree.Inclined plane can allow the sleet natural landing under gravity dropping on air inlet protective cover 9 top and air outlet protection cover 2 top, avoids rainwater to deposit or accumulated snow.In the present embodiment, as shown in Figure 1, air inlet protective cover 9 is surrounded by the four pieces of protective plates be arranged on around air inlet, and the protective plate be positioned at above air inlet is in tilted layout, and the vertical lower of air inlet does not arrange protective plate, forms ventilating opening; The structure of air outlet protection cover 2 is identical with the structure of air inlet protective cover 9.
Further, air inlet is in the below of air outlet, and air inlet is positioned at the bottom of the sidewall of cabinet 1.In the present embodiment, as shown in Figure 1, air inlet is in the below of one of them sidewall of cabinet 1, and air outlet is above the sidewall relative with the sidewall of air inlet place cabinet 1, and air inlet is identical with the shape of air inlet, cold air flows into cabinet 1 from lower, frequency converter work makes atmosphere temperature rising in cabinet 1, and hot-air moves upward, and flows out from the air outlet be positioned at above air inlet, by the kinetic characteristic of hot-air, be conducive to the free convection forming air.
As the enforceable mode of one, air inlet blower fan 11 is set in air inlet protective cover 9, in air outlet protection cover 2, sets out air port blower fan 12.Summer, outdoor temperature was higher, was separately positioned near air inlet and air inlet blower fan 11 near air outlet and air outlet blower fan 12 can obviously strengthen heat dissipation ventilation effect.In the present embodiment, air inlet blower fan 11 and air outlet blower fan 12 are the axial flow blower that power is larger, and make the air in cabinet 1 accelerate circulation, the power of air inlet blower fan 11 and air outlet blower fan 12 suitably adjusts according to the power of frequency converter.
Further, air outlet is 150mm ~ 200mm with the distance of the ventilating fan being placed in the frequency converter in cabinet 1.The position of air outlet is near the ventilating fan being positioned at frequency converter top, and the heat that the ventilating fan of frequency converter is discharged is discharged to rapidly outside cabinet 1, to frequency converter with works fine environment by the air outlet blower fan 12 at air outlet place.
As the enforceable mode of one, at the edge of the ventilating opening of the edge of the ventilating opening of air inlet protective cover 9 and air outlet protection cover 2, baffle plate slot 3 is set respectively, baffle plate (mesh type baffle plate 4 or closed type baffle plate 5) can quick insertion baffle plate slot 3, mounting means is simple, is convenient for changing baffle plate.
Outdoor frequency conversion tank also comprises change over switch and temperature detect switch (TDS), and temperature detect switch (TDS) opens and closes according to the temperature automatic control air inlet blower fan 11 in cabinet 1 and air outlet blower fan 12.Change over switch is by user's manual operation, and change over switch controls the keying of temperature detect switch (TDS); When temperature detect switch (TDS) damages or is malfunctioning, change over switch directly controls air inlet blower fan 11 and air outlet blower fan 12 opens and closes, temperature detect switch (TDS) and change over switch double control, in the outdoor environment of complexity, applicability is very strong, reliability is high, avoid temperature detect switch (TDS) to damage or malfunctioning time, air inlet blower fan 11 and air outlet blower fan 12 cannot start and cause temperature to raise.
The present invention is applied by field conduct, effective, flexibly and easily, cost-saving, extend the useful life of outdoor frequency conversion tank, eliminate because cabinet 1 internal temperature raises, and the intrusion of sleet and the component damage short circuit caused, earth fault, guarantee the safe operation of outdoor frequency conversion tank.
Above-described specific embodiment, has carried out further detailed description to object of the present invention, technical scheme and beneficial effect, should be appreciated that and the foregoing is only specific embodiments of the invention, the protection range be not intended to limit the present invention.Particularly point out, to those skilled in the art, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
