Description
Technical field
The present invention relates to electric fittings technical field, and in particular to the radiating adjusting method of distribution box.
Background technology
Distribution box is that switchgear, measuring instrumentss, protection electrical equipment and auxiliary equipment are assembled in into gold by electrical wiring requirement
Belong in cabinet or screen width, with reasonable distribution electric energy, the convenient switching action to circuit.The application field of distribution box is extensive, covers
Industry, agricultural, traffic, science and technology, environmental protection and people's lives etc..
When the electrical instrumentation component working in distribution box, various electrical instrumentation parts can produce heat, allow in distribution box
Temperature rise, if distribution box set in the wild, the irradiation of sunlight also can raise the temperature in distribution box, distribution box temperature
Rise can influence electrical instrumentation component working.Existing distribution box is typically that radiator fan is set in distribution box, by radiation air
Fan conducts heat by the heat emission hole on distribution box.But the heat emission hole size of distribution box is fixed, when temperature rise compared with
It can not in time be radiated when fast, make the work of influence electrical instrumentation part.
The content of the invention
The invention is intended to provide a kind of radiating regulation side for the distribution box that heat emission hole size is automatically adjusted when temperature raises
Method.
The radiating adjusting method of distribution box in this programme, including herein below：
S1, in the temperature ramp de in distribution box, fan makes the temperature liter at heat emission hole when heat is exported from heat emission hole
Height, the air allowed in the air bag on heat emission hole inwall are raised and expanded with temperature, and air expansion makes air bag swell, and air bag, which swells, to be pushed away
Dynamic iron block moves to the electromagnet side changed on plate, iron block is entered the magnetic journey scope of electromagnet；
S2, iron block, because magnetic attraction makes variation plate be adsorbed at air bag, allow variation plate to tilt to air bag and sentence increasing with electromagnet
The aperture area of big heat emission hole；
S3, when variation plate is tilted at air bag, the infrared receiving tube that plate covers sliding block top is changed, stop infrared receiving tube to red
The infrared light that outer transmitting tube is launched is received, and reduces the electric current for the infrared receiving tube that controller receives, controller control
Fan processed improves rotating speed；
S4, when variation plate is tilted at air bag, change plate and also moved down to movable slider, made on the through hole and case lid on sliding block
Stomata aligns to form the passage of radiating.
The beneficial effect of this programme is：In content S2, due to fan using air-flow as carrier by the heat in distribution box from
Heat emission hole distributes, and variation plate, which is tilted at air bag, increases heat emission hole aperture area, in same time, is overflow from heat emission hole
The throughput gone out is larger, can accelerate radiating.
In content S3, rotation speed of the fan improves, and makes exhaust air rate of the fan in same time bigger, the air-flow velocity of formation
Faster, accelerate to distribute the heat in distribution box.
In content S4, the passage of the radiating of through hole and stomatal limiting value, the quantity of radiating outlet is added, that is, is increased
The area of heat emission hole, faster, radiating effect is more preferable for radiating rate.
Plate is changed to be tilted towards the action of air bag, increases radiating hole area, improves the rotating speed of fan to accelerate to radiate, also
Other heat dissipation channels are added, are quickly distributed the heat in distribution box, radiating effect is more preferable.
Explain：Magnetic journey is the useful effect region of magnetic field force (magnetic force).
Further, in the content S2, rotating shaft is equipped with the exit of heat emission hole, torsion spring is worn in rotating shaft, will
The straight reverse arm of one of torsion spring is fixedly connected with changing plate, and another straight reverse arm of torsion spring is fixed on into the inwall of heat emission hole
On.
When variation plate is adsorbed onto at air bag by the attraction between iron block and electromagnet, torsion spring is produced elasticity by torsion
Deformation, and after the attraction between iron block and electromagnet reduces, torsion spring, which recovers elastic deformation, makes variation sheet reset, in distribution box
Temperature reduce after automatically reset, ensure to increase heat emission hole after temperature raises, accelerate radiating, without human intervention, using more
It is convenient.
Further, in the content S4, the profile of air bag is arranged to elliposoidal, and iron block is fixed on air bag towards change
On the point of dynamic plate side.
The air bag of elliposoidal can allow two tip expansions of air bag to extend, make iron block to electromagnet side when air expands
Mobile distance is bigger, ensures that iron block can enter in the range of the magnetic journey of electromagnet.
Further, in the content S4, by the end set of the fixation iron block of air bag into the end with retractility.
The end for only allowing air bag to fix iron block has a retractility, and air expansion makes the retractility of air bag bigger, allow iron block to
The magnetic journey scope displacement of electromagnet is bigger, ensures that iron block can enter the magnetic journey scope of electromagnet.
Further, in the content S4, the supporting plate spacing to sliding block is fixedly installed below stomata on case lid.
When sliding block is supported downwards by variation plate, stomata aligns rear slider with through hole to no longer moving down on the supporting plate,
Excessive distance is moved when avoiding sliding block from being supported downwards and covers stomata again.
Further, in the content S4, the stage clip for allowing sliding block to reset is set between supporting plate and sliding block.
When sliding block is supported downwards by variation plate, sliding block, which moves down, applies pressure to stage clip, and stage clip produces elastic deformation, when
When changing sheet reset, the pressure that stage clip is subject to cancels, and stage clip recovers elastic deformation and resets sliding block, convenient in next distribution box
Increase the hole of radiating after temperature rise.
