Abstract
The utility model discloses air exchange dehydrating unit in a kind of high-voltage board, comprise housing, described housing has air inlet and air outlet, and this air inlet is provided with aerofoil fan, and this aerofoil fan is connected to power supply by machine governor and switch.The utility model has the advantages that: energy consumption is low, use safety, and effect on moisture extraction is better.
Description
Technical field
The present invention relates to high-voltage board accessory technical field, especially relate to air exchange dehydrating unit in a kind of high-voltage board.
Background technology
At present, the dehumidification mode that high ferro electric substation high-voltage board adopts is commonly iodine-tungsten lamp roasting mode.Its defect is: 1, iodine-tungsten lamp power is usually at more than 1000W, and energy consumption is high, is unfavorable for energy-conservation; 2, the quartz glass tube surface temperature of iodine-tungsten lamp can reach more than 800 DEG C, and working temperature is high, has disaster hidden-trouble; 3, limited space in high-voltage board, inside cable is many, to such an extent as to the place of part crested cannot be toasted and put in place.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the object of this invention is to provide air exchange dehydrating unit in a kind of high-voltage board, it has, and energy consumption is low, use safety, and the good feature of effect on moisture extraction.
To achieve these goals, the technical solution adopted in the present invention is: air exchange dehydrating unit in high-voltage board, comprises housing, and described housing has air inlet and air outlet, this air inlet is provided with aerofoil fan, and this aerofoil fan is connected to power supply by machine governor and switch.
Described power supply is lithium battery group.
Described machine governor is connected with signal simulator.
Described air outlet place is provided with air filtration layer.
Described air outlet place is provided with calcium oxide wrapper.
Described housing is glass shell.
The present invention is compared to the prior art advantageously: energy consumption is low, use safety, and effect on moisture extraction is better.In high-voltage board of the present invention, air exchange dehydrating unit is applied in high-voltage board, and for providing clean and dry convected air in high-voltage board, effect on moisture extraction is better.Meanwhile, without the need to adopting the iodine-tungsten lamp of relatively high power, comparatively energy-conservation, and heat to distribute be zero substantially, safer.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the connection diagram of embodiments of the invention.

Embodiment
Embodiment, as shown in Figure 1: air exchange dehydrating unit in high-voltage board, comprises housing 10.Concretely, this housing 10 has air inlet 11 and air outlet 12.This air inlet 11 place is provided with aerofoil fan 20.That is, air sucks in this housing 10 from this air inlet 11 by this aerofoil fan 20, flows out afterwards from this air outlet 12.This aerofoil fan 20 is connected to power supply 50 by machine governor 30 and switch 40.This machine governor 30 is responsible for rotating speed analog signal being adjusted to relevant voltage and is controlled rotation speed of the fan.Usually, this aerofoil fan 20 adopts that voltage is 12V, power is 20W, maximum speed is the fan of 7000RPM; This machine governor 30 adopts that voltage is 12V, power is 150W machine governor, and it is with Single-chip Controlling, and installs tach signal analogue system additional.Like this, be applied in high-voltage board by air exchange dehydrating unit in this high-voltage board, for providing clean and dry convected air in high-voltage board, effect on moisture extraction is better.
Optimize:
This power supply 50 is lithium battery group.Usually, this lithium battery group is the lithium polymer battery group of 12V, 5000MAH, high-discharge-rate (40C).
This machine governor 30 is connected with signal simulator 60.Usually, the BEC signal end of this machine governor 30 is connected with tach signal simulator 60.The effect of this tach signal simulator 60 sends tach signal instruction to this machine governor 30, makes this machine governor 30 according to instruction adjusting rotary speed size.
This air outlet 12 place is provided with air filtration layer 70.This air filtration layer 70 can be HEPA ultra-fine fibre glass paper, its role is to purify the air exported.
This air outlet 12 place is provided with calcium oxide wrapper 80.Like this, air exchange dehydrating unit in this high-voltage board is enable to export comparatively dry air.
This housing 10 adopts glass shell.The advantage of employing glass shell is: insulating properties is high, antistatic, intensity are high, corrosion-resistant, is applicable to various adverse circumstances.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
