Description
Technical field
The invention belongs to electrical equipment technical field, particularly a kind of non-maintaining anti-condensation switch cabinet.
Background technology
High-tension switch cabinet inner space is extremely compact, during wet season, contains more vapor in air, can make in switchgear
Insulating part, locally have dew condensation phenomenon in electrical body surface or switchgear；So as to mould growth, accelerate metallic conductor corrosion, lead
Contact surface oxidation is caused, contact resistance increase, causes electrical insulation strength to reduce.And cause in-cabinet temperature to be less than the outer temperature of cabinet,
Temperature difference is formed inside and outside cabinet, causes dew condensation phenomenon.Causing insulation spacing to cause, climbing for electrical equipment is electric, abnormal flashover electric discharge is existing
The generation of elephant, causes phase fault to cause equipment fault to be tripped, and the safe and stable operation to equipment brings hidden trouble.
Have in the prior art prevents condensation in distribution box by silica-gel desiccant to adsorb vapor, and uses which
Silica dehydrator dosage is consumed greatly, it is necessary to which in due course replacement silica-gel desiccant, use cost are high.
The content of the invention
The present invention is in view of the shortcomings of the prior art, provide a kind of non-maintaining anti-condensation switch cabinet, this kind of switchgear can be effective
Prevent inside switch cabinet element surface from dew condensation phenomenon occur, prevent from climbing the generation of electricity, abnormal flashover electric discharge phenomena, improve switchgear
Security performance, and from safeguard.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：It is a kind of non-maintaining anti-condensation
Switchgear, including cabinet, are provided with some ventilating openings on the cabinet, dehumidifying ventilation unit, institute are provided with the ventilating opening
Stating dehumidifying ventilation unit includes barrel-type casing, and two Dehumidifying elements and fan overlapped up and down, institute are provided with the housing
Stating Dehumidifying element includes Vertical Channel, and the channel roof is connected with drier case by spring, and the drier case both sides are set
The first opening of silk screen parcel is equipped with, the passage is provided with the second opening towards the side outside cabinet, and the passage opposite side is set
The 3rd opening is equipped with, is provided with silica-gel desiccant and heating wire in the drier case, the drier bottom portion is provided with two
Conductive contact and electromagnet, the heating wire and the electromagnet are connected with the conductive contact, and the channel bottom is set
There are two conductive contact blades coordinated with two conductive contacts and the first iron block coordinated with the electromagnet, the conductive contact blade
It is connected with power supply, when the drier case slides into the channel bottom, first opening and second open communication
And disconnected with the described 3rd opening；When drier case is located at remaining position of the passage, first opening, described second open
Mouth is connected with the described 3rd opening；The drier box top of lower section is provided with the coordinated with the electromagnet of top
Two iron blocks.This kind of switchgear is rotated by fan divulge information when in use, and channel floor is touched when the drier case of top absorbs water to
During portion, electric-heating-wire-heating silica-gel desiccant discharges aqueous vapor, while electromagnet attracts the first iron block and the second iron block so that top
Drier case can delay to rise so as to more it is dry a little while so that the drier case of lower section can delay to decline so as to inhale one more
Section time aqueous vapor, so that it is asynchronous to ensure that two drier casees slide, ensures at least one drier case ventilation, passes through heating wire
Enable the switchgear to circulate the aqueous vapor removed in access switch cabinet always the aqueous vapor discharge in silica-gel desiccant, prevent from coagulating
Dew.
In above-mentioned technical proposal, it is preferred that the passage is provided with stomata towards cabinet outside.Stomata is set to cause drying
Agent case slides more smooth in slideway.
Compared with prior art, the present invention have the advantages that：This kind of switchgear is rotated by fan when in use
Ventilation, when the drier case of top, which absorbs water to, touches channel bottom, electric-heating-wire-heating silica-gel desiccant discharges aqueous vapor, together
When electromagnet attract the first iron block and the second iron block so that the drier case of top can delay to rise so as to more it is dry a little while,
Enable the drier case of lower section to delay to decline so as to inhale a period of time aqueous vapor, so as to ensure that two drier casees slide not more
It is synchronous, ensure at least one drier case ventilation, the aqueous vapor in silica-gel desiccant is discharged by the switchgear by heating wire
The aqueous vapor removed in access switch cabinet can be circulated always, prevent condensation.
