The normal operation of electric cabinet.
Existing power distribution cabinet is in distribution indoor location air-conditioning temperature-reducing equipment for overtemperatute one, by reducing environment
Temperature is regulated and controled, and the power distribution cabinet for outdoor mounted is only capable of relying on BAIYE fan to carry out basic aeration-cooling, not only lowers the temperature
Effect is bad, and so that a large amount of dusts is entered it is difficult to clear up in cabinet, and for short-circuit flare problem, does not still have at present
There is rational solution；Additionally, because being provided with substantial amounts of components and parts in power distribution cabinet, when being given a shock it is easy to cause even
Link gets loose, or even because vibrations are excessive causes component damage, these are all the more problems met in routine use.
Chinese patent Authorization Notice No. cn205092478u discloses a kind of fire-proof electrical control cubicles, and it is gone out using dry ice
Fire and cooling, but its ventilation unit of being furnished with make inside and outside carry out air circulation, no any Insulation simultaneously, inner cryogenic ring
Border can eliminate quickly, subsequently replys hot environment again, so in the past, dry ice consumption is high, simultaneously no any safety measures,
If, it is easy to cause personnel's cold injury, its practicality is not high for the detection means operating emission dry ice when personnel overhaul.
In addition to overtemperature problem on fire, in carrying and installation, and the power distribution cabinet internal component of the open air of setting can be subject to
To larger shock, existing power distribution cabinet is not equipped with any glissando, and impact power is inhaled by internal component completely
Receive it is easy to cause circuit to come off or device damage, and Authorization Notice No. cn203826814u provide a kind of damping power distribution cabinet,
Using spring whole cabinet is carried out with damping, but it to the impulsive force of left and right directions and is applied to rushing on internal installing plate
Hit power damping effect bad, power distribution cabinet real it is desirable that protection to components and parts on installing plate, rather than to whole power distribution cabinet
Cabinet carries out protecting damping.
