A kind of moistureproof high temperature-proof electric power cabinet
Technical field
The invention belongs to electrical circuitry equipment field, be specifically related to a kind of moistureproof high temperature-proof electric power cabinet.
Background technology
Electric power cabinet is equipment the most crucial in power supply unit, and the most of weight of itself all concentrates on drawer,
Therefore, when drawer is extracted out and carried out specific works when, center of gravity then can move forward, thus be easily caused switch board and turn forward
Fall, but if be fixedly connected with the ground by switch board, then hinder the electric power cabinet movement when performing other tasks.
The dampness that may get off at outside work, high temperature and long term accumulation for a long time due to electric power cabinet will affect in electric power cabinet
Portion's precision element, current electric power cabinet has dehumidification function a bit, but otherwise cost is higher, however effect is not clearly.
Current electric power cabinet is merely capable of solving the task problem of its routine, and the performance for cabinet itself is seldom paid close attention to,
As worked out of doors for a long time due to it, its safety is difficult to be protected, and existing electric power cabinet is in order to prevent from being destroyed, conventional
Use the mode being fixed on ground, but be many times required for movement in real time, if being fixed on ground owing to electric power cabinet has
Then can not move in real time and need to newly increase new switch board unit, thus greatly increase cost.
The when of work out of doors due to it, opposing ambient weather is also very important to the destruction of inner member, existing
Having switch board routine is to use the straight carbon steel antirust material of matter mopping to make, and intensity and corrosion resistance are the most less desirable, due to interior
Portion's element is all expensive force device, and the research and development thinking little of enclosure material likely can cause the biggest loss.
Along with the propelling of intelligent science and technology, power equipment is also required to the support of these technology and reaches to reduce manpower and materials
Technique effect.

1, carry out detachable fix by overall for electric power cabinet with ground by arranging position control, thus prevent
Electric control drawer box release after the generation toppling over phenomenon of electric power cabinet, by by itself and the supporting setting of push-pull device at fixed, the
One push-pull bar release while (i.e. drawer release while), the second push-pull bar is released the most simultaneously so that position control bar also to
Outside mobile, it is connected with position spud pile so that grip in advance and clamps, when the first push-pull bar is regained when, the second push-and-pull
Bar is also regained, and grips the most in advance and also can depart from from the spud pile of position, thus electric power cabinet is fixedly connected with the ground disconnection, can be overall
Move to desired location and carry out other operations.
The moistureproof high temperature-proof device matched with position control bar by setting, when position control bar is displaced outwardly
Waiting, the rotary shaft with fan and compliant member is also displaced outwardly, thus compliant member contacts with radiator-grid, disposes radiator-grid
On dust and other impurities, thus improve radiating efficiency, reach the effect of high temperature-proof, owing to being additionally provided with flabellum in rotary shaft, when adopting
After being fallen by eliminating impurities on radiator-grid with compliant member, what wind just can more be filled up by flabellum blows out shell by radiator-grid,
Owing to being provided with desiccant case outside radiator-grid, and the air circulation within electric power cabinet is totally discharged by this flabellum, is therefore
Can be discharged by radiator-grid by inside malaria, be provided with desiccant, the humid air of this discharge then will not continue to humidity
Rest on ambient envelope, thus reach moistureproof effect.
By being provided with the push-pull device at fixed that can move up and down so that the Electric control drawer box of moistureproof high temperature-proof electric power cabinet
Can pull open or regain by a key, thus change employing manpower before and carry out push-and-pull thus cause the damage of internal power element to ask
The appearance of topic.
By the magnesium alloy constituent content of enclosure material and microstructure being improved so that its intensity and anticorrosive
Property is improved, especially after rationally adding and adjusting the content of Bi trace with the addition of rare earth RE, thus at cheap element
In the case of Bi obtains thinning effect to crystal grain, with the addition of RE further and carry out the further refinement of crystal grain so that be nano level
Mg3Bi2The amount of phase gets a promotion.So that the intensity of magnesium alloy is remarkably enhanced.
2, by arranging signal processing module and the signal transmission module of inside, and by two inside modules chips
Concrete layout, it is possible in time efficient send the image high definition of intelligent video camera head to supervision department, it is achieved thereby that anti-
Tide high temperature-proof electric power cabinet the most controlled.
3, by coordinating of supervising device and alarm device, prevent the moistureproof high temperature-proof electric power cabinet worked out of doors from being anticipated
Outer thinking destroys or stealing, owing to signal transmission module all can be transmitted, when moistureproof anti-height by wirelessly or non-wirelessly pattern
Errorless for video signal still can be transmitted by the destroyed rear signal transmission module of wired connection of temperature electric power cabinet.Report to the police and fill
Put by being electrically connected with cabinet door lock, i.e. start after cabinet door lock is locked, after cabinet door lock is destroyed, alarm
Buzzer i.e. carries out the warning of high-decibel, and after protection against the tide high temperature-proof electric power cabinet is moved by destruction personnel entirety, Vibration induction
Device also triggers the buzzer of alarm, thus frightens destruction personnel, and is passed in real time by video by supervising device
Send general headquarters back to.
