Net cabinet condensation provides a kind of unpowered dehumidifying condensation proof device of ring network cabinet.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: ring network cabinet is unpowered, and dehumidifying is anti-condensation
Reveal device, including the first ventilation duct, the second ventilation duct, unpowered extractor fan and self-draining arrangement, ring network cabinet it is opposite two
A side lower passes through pipeline respectively and is connected to L-shaped first ventilation duct and the second ventilation duct, wherein the top of the first ventilation duct
It is connected by three-way connection with two elbows, Open Side Down is two air inlets for two elbows, passes through at the top of the second ventilation duct
Thrust bearing is connected with the unpowered extractor fan that can be horizontally rotated, and the self-draining arrangement is mounted on the water of the second ventilation duct
On flat pipeline；
Unpowered extractor fan is the hollow ball-shape of bottom opening, has multiple arcs blade, adjacent blade on sphere
Between misplace and have gap；
Self-draining arrangement includes blind nut and drainage cavity, and short tube straight down is connected to the horizontal pipeline of the second ventilation duct
On, blind nut is threadedly attached on short tube, and drainage cavity is the reversed arced tip cavity being fixed on blind nut, is opened at tip
There is water outlet.
First ventilation duct and the second ventilation duct is CPVC pipe.
The U section turned downwards is provided in the horizontal pipeline of second ventilation duct, the self-draining arrangement is mounted on U
On the horizontal component of shape section.
The utility model has the advantages that compared with prior art.
1, the utility model structure is simple, easy for installation, low in cost, significant effect, energy conservation and environmental protection, safety and stability, longevity
Life is extremely long, reduces the air humidity inside ring network cabinet, it is therefore prevented that the formation of northern area autumn and winter condensation reduces by condensation
Caused by ring network cabinet failure and line tripping, improve the reliability of power system power supply.
2, in the utility model unpowered extractor fan nature gentle breeze and two ventilation air in tubes convective zone
Dynamic lower rotation can be discharged the moisture inside ring network cabinet, go back on the second ventilation duct to accelerate the exchange of ring network cabinet inner air and outer air
Self-draining arrangement is installed, the condensation generated in the second ventilation duct can be automatically drained out.
