Description
Technical field
The utility model relates to a kind of a kind of separation of the aqueous vapor of moisture separator more particularly to for transformer vacuum oil
Device.
Background technique
Before high-power transformer oiling, reply transformer body is vacuumized.Its first purpose is to check the seal shape of transformer
Whether condition is good, the second is taking out the intracorporal air pocket of case and moisture, it is ensured that the insulation performance of transformer.Generally use water ring
Formula vacuum pump vacuumizes transformer body, its advantage is that it is high-efficient, speed is fast.But once motor has a power failure suddenly, due to become
It is negative pressure inside depressor, the recirculated water in water-ring vacuum pump impeller will be inhaled into transformer body.
Summary of the invention
The purpose of this utility model is to provide a kind of moisture separators of for transformer vacuum oil, can prevent water
Recirculated water in circular vacuum impeller of pump is inhaled into transformer body.
In order to achieve the above object, the utility model adopts the following technical solution:
A kind of moisture separator of for transformer vacuum oil, including closed cylinder, the top of the cylinder are equipped with
First extraction valve, the intracorporal middle and upper part of cylinder be equipped with multiple baffles that block water, it is the multiple block water baffle along the cylinder axis
To setting and the multiple baffle that blocks water is parallel to each other, and air flue is formed between the multiple baffle that blocks water, two neighboring described
The baffle that blocks water covers the cross section of the cylinder after being overlapped up and down, the side lower of the cylinder is equipped with the second extraction valve, described
The bottom end of cylinder is equipped with discharging valve.
Further, the baffle that blocks water is fan-shaped, and the round angle of the sector is greater than 180 °.
Further, the baffle that blocks water blocks water slot equipped with multiple concentric fan annulars.
Further, the upper surface of the baffle that blocks water is obliquely installed.
Further, the intracorporal bottom of the cylinder is in the recessed portion for being equipped with taper with the discharging valve connectivity part.
Further, the top of the cylinder is equipped with pressure vacuum gauge.
After adopting the above technical scheme, the utility model has the advantages that
The extraction valve one of moisture separator connects transformer non-return valve, and extraction valve two connects vacuum pump, true using liquid-ring type
Sky pump is when vacuumizing transformer body, and moisture separator can be sucked out by the way that the baffle that blocks water will be due to inside transformer negative pressure
The recirculated water of vacuum pump is trapped in moisture separator, and recirculated water is avoided to be inhaled into transformer body, when oiling finishes, can be opened
The recirculated water of suck-back is discharged in discharging valve.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the moisture separator of for transformer vacuum oil in embodiment.
Fig. 2 is the structural schematic diagram of baffle of blocking water in embodiment.
Specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of moisture separator of for transformer vacuum oil, including closed cylinder 51.
The top of cylinder 51 is equipped with the first extraction valve 52, and the first extraction valve 52 is for connecting transformer non-return valve, cylinder 51
Side lower be equipped with the second extraction valve 55, for connecting water-ring vacuum pump, the bottom end of cylinder 51 is equipped with the second extraction valve 55
Discharging valve 56.
Middle and upper part in cylinder 51 is equipped with multiple baffles 53 that block water, it is multiple block water baffles 53 along cylinder 51 axial setting and
Multiple baffles 53 that block water are parallel to each other, and are formed with air flue 54 between multiple baffles 53 that block water.
Since gas-vapor mix air-flow is vertical ascent in moisture separator, therefore two neighboring about 53 baffle that blocks water weighs
Poststack covers the cross section of cylinder 51, and steam is avoided to be inhaled into transformer without barrier.When oiling finishes, discharging valve can be opened
56, the recirculated water of suck-back is discharged.
Motor have a power failure when, the recirculated water suck-back of water-ring vacuum pump, with air-flow formed air-water mixture, air-water mixture into
Enter into moisture separator, the baffle that blocks water is blocking water Vapor adsorption on baffle, is inhaled into transformer to avoid recirculated water.
As shown in Fig. 2, the baffle 53 that blocks water is fan-shaped in the present embodiment, fan-shaped round angle is greater than 180 °.
Further, the baffle 53 that blocks water is equipped with multiple concentric fan annulars and blocks water slot 531.The effect of slot of blocking water is: one,
Increase blocks water baffle area, with the ability for baffle sorption cycle water of reinforcing blocking water；Two, play the circulation being adsorbed on the baffle that blocks water
The guide functions of water.
Further, the block water upper surface of baffle 53 is obliquely installed, and is inclined naturally convenient for water and is dropped down onto moisture separator bottom.
In the present embodiment, the bottom in cylinder 51 is in the recessed portion 57 for being equipped with taper with 56 connectivity part of discharging valve.
In the present embodiment, the top of cylinder 51 is equipped with pressure vacuum gauge 58.
In addition to above preferred embodiment, for the utility model there are also other embodiments, those skilled in the art can root
It is made various changes and modifications according to the utility model, without departing from the spirit of the utility model, should belong to the utility model
Range defined in appended claims.
