Description
Technical field
The present invention relates to a kind of electrical equipment, specifically a kind of shatter-proof fire-retardant free-standing low temperature power distribution cabinet.
Background technology
Power distribution cabinet is the final stage device in power circuit, is mainly used for the various integration with electrical component and puts and mutually powered-down
The monitoring of piezoelectricity flow data shows that power distribution cabinet generally more to be placed in special switchgear house, also has a small number of placements outdoors, distribution
During the use of cabinet, relatively common problem one is overtemperature, and one is flare that short circuit causes, is matched directly affecting
The normal operation of electric cabinet.
Existing power distribution cabinet is in distribution indoor location air-conditioning temperature-reducing equipment, by reducing environment for overtemperatute one
Temperature is regulated and controled, and the power distribution cabinet of outdoor mounted is only capable of to carry out substantially aeration-cooling by blinds fan, is not only cooled down
Effect is bad, and is easy that a large amount of dusts is made to enter in cabinet, it is difficult to it clears up, and for short-circuit flare problem, do not have still at present
There is rational solution；In addition, because being equipped with a large amount of component in power distribution cabinet, when being given a shock, it is easy to cause to connect
Link loosens, or even because vibrations are excessive to cause component damage, these are all more the problem of meeting in routine use.
Chinese patent Authorization Notice No. CN205092478U discloses a kind of fire-proof power control cabinet, is gone out using dry ice
Fire and cooling, but its ventilation device being furnished with makes inside and outside progress air circulation, while without any Insulation, inner cryogenic ring
Border can be eliminated quickly, then reply hot environment again, and so previous, dry ice consumption is high, while without any safety measures,
If the detection device operating emission dry ice when personnel overhaul, it is easy to cause personnel's frostbite, the practicality not high.
Other than overtemperature problem on fire, in carrying and installation, and the outdoor power distribution cabinet internal component of setting can be by
To larger shock, existing power distribution cabinet is not equipped with any glissando, and impact power is inhaled by internal component completely
It receives, it is easy to cause circuit to fall off or equipment damage, and Authorization Notice No. CN203826814U provides a kind of damping power distribution cabinet,
Damping is carried out to entire cabinet using spring, but it to the impact force of left and right directions and is applied to rushing on internal mounting plate
Power damping effect and bad is hit, what power distribution cabinet really needed is the protection to component on mounting plate, rather than to entire power distribution cabinet
Cabinet carries out protection damping.
