Description
Technical field
The utility model is related to technical field of electric power, more particularly, to the dual dry micro-positive pressure of enclosed busbar device of one kind.
Background technology
Power station enclosed busbar connecting generator and main transformer, are the passes for preventing generator outlet from occurring short-circuit major accident
Button apparatus.In order to ensure the safe operation of enclosed busbar, the dry air of cleaning is filled with to enclosed busbar inside so that closing is female
Air pressure inside line is slightly larger than the air pressure of surrounding, so prevents the moisture in air and generator outlet cell from letting out
The hydrogen of dew enters inside enclosed busbar, it is ensured that the dielectric strength of bus and safe operation.This is that enclosed busbar is generally used
Mature technology measure.But existing micro positive pressure device drying step typically only passes through a kind of drying equipment, make to enter closing mother
The humidity of gas in line is higher, while drying chamber is typically made by the way of welding, delivery efficiency is low, and tank skin is typically iron
System, make drying chamber quality weight cost high.
Utility model content
The purpose of this utility model is to provide the dual dry micro-positive pressure of enclosed busbar device of this one kind, simple and reasonable,
Drying capacity is strong, and small volume, lightweight and cost is low, and production efficiency is high.
To achieve the above object, the utility model provides a kind of dual dry micro-positive pressure of enclosed busbar device, including envelope
Close bus, the air compressor communicated with the enclosed busbar, drying device and control device, the drying device include with
Freezing type drier that the air compressor is connected and the drying chamber being connected with the freezing type drier, the drying
Tank is connected with the enclosed busbar by operated pneumatic valve.
It is preferred that, the drying chamber is absorbed type drying tank, and the absorbed type drying tank is provided with two, two suctions
Attached formula drying chamber is connected by valve.
It is preferred that, the absorbed type drying tank is by top cover, base, tank skin and is arranged in the absorbed type drying tank
Molecular sieve is constituted.
It is preferred that, the top cover is bolted to connection with the tank skin, and the tank skin is made up of aluminum alloy, described
Base bottom is additionally provided with bleed hole and filtration.
It is preferred that, the control device includes pressure sensor, humidity sensor, PLC and sound and light alarm dress
Put.
Therefore, the utility model uses a kind of dual dry micro-positive pressure of enclosed busbar device of said structure, simple in construction
Rationally, drying capacity is strong, and small volume, lightweight and cost is low, and production efficiency is high.
Below by drawings and examples, the technical solution of the utility model is described in further detail.

Embodiment
Embodiment
Fig. 1 is a kind of dual dry micro-positive pressure of enclosed busbar apparatus structure schematic diagram of the utility model, and Fig. 2 is that this practicality is new
A kind of dual dry micro-positive pressure of enclosed busbar device drying chamber structural representation of type, as illustrated, dual dry enclosed busbar is micro-
Positive pressure devices, including enclosed busbar 5, the air compressor 1, drying device and the control device that are communicated with enclosed busbar 5, are dried
Device includes the freezing type drier 2 being connected with air compressor 1 and the drying chamber being connected with freezing type drier 2, does
Dry tank is connected with enclosed busbar 5 by operated pneumatic valve 4, and gas first passes through freezing type drier 2 and carries out preliminarily dried, then passes through
Drying chamber is dried, and the humidity of gas is reached requirement, drying effect is more preferable.
The present embodiment drying chamber selects absorbed type drying tank 3, and absorbed type drying tank 3 is provided with two, and two absorption types are done
Dry tank 3 is connected by valve, and absorbed type drying tank is by top cover 31, base 33, tank skin 32 and is arranged at absorbed type drying tank 3
Interior molecular sieve is constituted, and top cover 31 is bolted to connection with tank skin 32, easy to assembly quick, it is not necessary to weld, and is reduced defeated
Go out cost, tank skin 32 is made up of aluminum alloy, ensure that the intensity requirement needed for tank body, while light weight, antiseptic property is strong,
And itself has excellent heat dispersion and heat-conductive characteristic, has certain adsorption capacity, bottom to source of the gas inside contained humidity
33 bottoms of seat are additionally provided with bleed hole and filtration 34, and gas enters in drying chamber by bleed hole, and filtration 34 ensures gas
Molecular sieve while source is passed through inside drying chamber will not be leaked.
Control device includes pressure sensor, humidity sensor, PLC and acoustic-optic alarm, when closing is female
Pressure in line is excessive or device is just alarmed by warning device during small and overtime pressure, stops when the humidity poured is excessive
Only inflate and alarm, it is ensured that the gas poured in enclosed busbar 5 meets the requirements.
Therefore, therefore, the utility model uses a kind of dual dry micro-positive pressure of enclosed busbar device of said structure, structure
Advantages of simple, drying capacity is strong, and small volume, lightweight and cost is low, and production efficiency is high.
Above is embodiment of the present utility model, but protection domain of the present utility model should not be limited to this.Appoint
What those skilled in the art is in the technical scope disclosed by the utility model, the change or replacement that can be readily occurred in,
It should all cover within protection domain of the present utility model, therefore protection domain of the present utility model should be limited with claims
Fixed protection domain is defined.
