Specific embodiment
Below in conjunction with attached drawing, specific embodiment of the present utility model is illustrated.
What Fig. 1 illustrated the utility model suppresses surge tank 1 comprising the surge tank ontology 10 of a cylindrical body, it is internal
Equipped with insulating oil, there is an oil outlet 11 close to cylinder bottom position, the position on side wall at the top of cylindrical body
With a pressurization mouth 12 and an observation window 13.The top of the surge tank ontology 10 is to pass through in Flange-shaped Parts and side wall
The air-tightness top cover 14 of bolt fastening, top cover 14 are equipped with exhaust valve 15, can be used for being discharged inside the surge tank ontology 10
Air.It sets in the bottom of the surge tank ontology 10 there are three support leg 16, the support leg 16, which has, is fixedly connected on institute
The vertical pole 162 stating the cross bar 161 on 10 bottom surface of surge tank ontology and connecting with the cross bar 161, the vertical pole 162 pass through spiral shell
Bolt and nut are connect with the cross bar 161, and pass through the connection position of bolt and the nut adjustable vertical pole and cross bar
It sets, so as to adjust the height of the support leg 16.It is additionally provided with blowdown valve 17 in the bottom of the surge tank ontology 10, for arranging
Waste liquid or bottom sediment in the surge tank out.
Surge tank 1 of suppressing in the present embodiment is outer factice bellows surge tank, internal to have inflatable air bladder,
Air bladder passes through 12 inflating pressure of pressurization mouth.It is suppressed described in and opens the top cover when injecting insulating oil in surge tank 1
14, insulating oil is filled into oil pocket, later closed roof, and discharge remains in the air in oil pocket from the exhaust valve 15.
Alternatively, air bladder can also not had by suppressing surge tank 1, insulating oil, insulating oil are stored in inner cavity
The space of top is air, and the air that pressurization mouth 12 is pressed into directly increases the air pressure of insulating oil upper air.Pressurize mouth 12 simultaneously
It can also be used as pouring orifice, insulating oil is by suppressing surge tank 1 described in pressurization mouth injection.
In the present embodiment, it is additionally provided on pressurization mouth 12 and suppresses table (not shown), can intuitively shown
Suppress the pressure in surge tank 1.
Fig. 2 illustrates the situation suppressing surge tank and being connected on oil-immersed power transformer of the present embodiment, described to suppress
Surge tank 1 is placed in the top of the power transformer, and power transformer includes transformer body 2, and is arranged in the transformer
The inner oil type metal bellow oil conservator 21 at 2 top of ontology, the oil conservater 21 are connected to the transformer body by pipeline 22
2, there is a three-way valve 23 on pipeline 22, the interface of three-way valve 23 is connected to by metal bellows and described suppresses buffering
The transformer body 2 can selectively be connected to and described suppress surge tank by the oil outlet 11 of tank 1, the three-way valve 23
1 or oil conservater 21.
When the power transformer completes oiling process and needs to carry out bulge test, the three-way valve is operated
23, the oil circuit between the oil conservater 21 and the transformer body 2 is cut off, is also turned on and described suppresses surge tank 1 and transformation
Oil circuit between device ontology 2.
It is then suppressed by described 12 Duis of pressurization mouth and is pressurizeed in surge tank 1, the pressure in tank is caused to reach test value, observed
Pressure can be confirmed in the table of suppressing.Atmospheric pressure is transmitted to the insulating oil suppressed in surge tank 1, is then passed to the change
Insulating oil in depressor ontology 2 makes the pressure in transformer body 2 reach test value.
Process time to be achieved needed for carrying out bulge test process in power transformer is usually 24 hours to 72 small
When, oil conservater 21 and transformer body 2 are also at static condition simultaneously during this period, therefore resting process and bulge test are simultaneously
By carry out.During transformer body 2 carries out bulge test, oil conservater is not subject to identical pressure because oil circuit is cut off,
Therefore any damage will not be caused to inner oil type wavy metal structure.
