Definitions
- the invention relates to a method for reducing the supply of air from the atmosphere in the expansion vessel filled with insulating high-voltage systems.
- the invention also relates to a device for carrying out the method, the design of which differs when new starting up of transformers from the already used in transformers thermal aging.
- High-voltage systems eg transformers
- insulating liquids eg mineral oil
- the latter are taken up by expansion vessels above the transformer tank.
- the pressure equalization to the atmosphere via a pipe, which is closed at its end with a dehumidifier and an oil bell.
- an air supply from the atmosphere occurs when with the onset of thermal aging of oxygen in the active part of the transformer is consumed as well as degassed insulating fluids during re-saturation (re-commissioning, repairs).
- DE 10035947 B4 discloses an apparatus for reducing the contamination of liquids by air mixture and water.
- This device consists of the main container in which there is the heat source, which is connected in its lower part with a tube with the Dilatations electer; which flows freely into the surrounding atmosphere. Between the pure and warm liquid, a stable layer of thermal stagnation forms, which is spontaneous under the heat source at the boundary layer to the underlying cold potentially Contaminated liquid, which is located in the lower part of the main container, the connecting tube and Dilatations capableer arises.
- the aim of one's invention is to make the expansion vessel, in particular with direct air contact, in order to obtain a sustainable reduction of the oxygen content and to reduce the moisture input from the atmosphere.
- the object of the invention is to provide a connected to the expansion vessel of the high voltage system, non-lockable air buffer space, which restricts the use of air caused by the gas budget of the Isolier crampkeitssystems air entry from the atmosphere and utilize that with the onset of thermal aging of the insulation system simultaneously in the liquid Dissolved oxygen is consumed, so as to get a reduction in the oxygen content of the air in the expansion vessel and thus reduce the oxygen consumption by continuous feedback and to reduce the moisture input.
- the object is solved by the features illustrated in the claims.
- the basic idea is to use an external breathing buffer selectable in combination with the use of an inert gas.
- gas according to the invention is discharged from the buffer space through a pipe opening in the shell of an inner, smaller tank, and at
- an inert gas is fed into the buffer space for faster and greater reduction of the air supply from the atmosphere when the pressure falls below the atmospheric pressure.
- the stability of the gas balance can be improved by setting an upper and lower limit in the buffer space for the absolute pressure, outside of which a pressure equalization with the atmosphere takes place.
- Dehumidifier of the expansion tank increases the reduction of the air supply from the atmosphere into the expansion tank. The same can be achieved if the buffer space of a tank with an air-impermeable buffer bag is increased.
- the method can be used both in expansion vessels with direct contact between insulating liquid and gas space as well as in expansion vessels with separating membrane.
- a one-way cock is preferably arranged in the upper region of the jacket.
- a float switch may also be arranged, which is connected via a valve to a pressure vessel of an inert gas.
- a manifold with the dehumidifier of the expansion vessel.
- this can be connected to a volume-variable buffer bag.
- a pressure sensor in conjunction with a freely opening to the atmosphere valve.
- the outer and inner tanks may be cubic or cuboid.
- the inner tank has a bottom and is arranged next to the outer tank in the manner that a wall is shared, in the lower region of a pipe joint is arranged at a predetermined height.
- the entire device is not lockable.
- Fig. 1 shows a schematic representation of the device according to the invention on the expansion vessel of a transformer, which is not connected shut-off.
- the device consists of an outer closed, cylindrical tank 1, in whose lid 2 a second, smaller cylindrical tank 3 is inserted centrally.
- the tanks 1 and 3 may also be cubic or cuboid.
- the inner tank 3 has no bottom, is spaced from the bottom of the outer tank 1 and has in the lower part of the shell a pipe opening 4, which leads via a pipe 5 in the upper part of the tank 3.
- the inner tank 3 has its own lid 6.
- the jacket of tank 1 has below the upper edge of a nozzle 7, and a one-way valve 11.
- a float switch 12 is disposed in the lower region, which is connected via a valve 13 with a pressure vessel of an inert gas.
- a compensating tube 8 In the upper part of the shell of the inner tank 3 is inserted a compensating tube 8 and leads horizontally through the shell of the outer tank 1 to the outside and is open at the bottom.
- tank 3 The lid 6 of tank 3 is removed and tanks 1 and 3 are partially filled with a precisely determined volume of an insulating liquid 14, eg transformer oil, which may be without quality requirements.
- an insulating liquid 14 eg transformer oil, which may be without quality requirements.
- This creates a buffer space 15 in the outer tank 1 above the insulating liquid 14, which is connected via the dehumidifier 9 with the air space of the expansion vessel 10 and forms a unit with this.
- the insulating liquid 14 has the task of a diffusion barrier for oxygen between the air in the expansion vessel 10 and the atmosphere.
- the tube opening 4 in tube 5 serves to take over the free gas exchange between the buffer space 15 and the atmosphere in order not to move the insulating liquid 14 as a diffusion barrier.
- floating body 17 can be introduced to cover the Isolier crampkeitsober Structure in the tank 3 and tube 5.
- To reinforce the diffusion barrier pipe 5 may also be a U-tube 20, which has openings 21 below and also passes through tank 1, in which case floats 17 are introduced ( Fig. 2 ). These floats 17 are filled, for example via two covers 22 in the lid 2 in the tank 1.
- a nozzle with closure 25 is attached to the connection of a buffer bag.
- both tanks 1 and 3 and the filling volume of the insulating liquid 14 are derived from the selected operating temperatures, the predetermined pressures and the Isolierteilkeitseigenschaften.
- the outer tank 1 is preferably protected from the outside against solar radiation in order to suppress temperature differences in the insulating liquid 14. In extreme minus temperatures, heating should also be possible.
- the installation of the device according to the invention must be horizontal.
- T u and T o For the choice of the operating temperatures T u and T o , it is often sufficient to refer to the highest summer temperature and the lowest winter temperature of the boiler oil during power operation. At temperatures below T u then a limited supply of air from the atmosphere can be accepted. The only small oxygen input is consumed again in the dissolved state.
- the added oil column height in the outer tank 1 and inner tank 3 is the time-varying diffusion barrier for gases, especially for oxygen.
- Parallel to the air buffering in the outer tank 1 takes place in the expansion vessel 10, a constant gas exchange between the air and the convective boiler oil instead.
- the oxygen content of the air in the expansion vessel 10 or in the buffer space 15 is increasingly decreasing.
- the replenishment of oxygen from the expansion vessel 10 stops in the boiler.
- the maximum lowering of oxygen is limited by the quality of the diffusion barrier.
- the expansion vessel 10 and the outer tank 1 can be flushed directly into the filling line 19 of the expansion vessel 10 via the one-way valve 11 by introducing inert gas directly with the process application.
- the monitoring of the effectiveness of the reduction in the oxygen content can be occupied by air samples from the one-way valve 11.
- the criterion for the effectiveness of lowering the oxygen content in the expansion vessel 10 can only be the absolute oxygen content in the airspace itself. About him can be concluded on the dissolved oxygen levels, not the other way around.
- inert gas is passed through a valve 13, which is controlled by a float switch 12 on the shell of the outer tank 1, the outer Tank 1 supplied.
- the maximum Inertgaszu operation until the overpressure to atmospheric pressure, which is calculated in the simplest case possible over a time limit. Since no air from the outside enters the system, u.a. the dehumidifier is spared.
- This version is preferable for new start-up and operating conditions where degassed insulating fluid is present.
- valve 13 instead of valve 24 can be switched when falling below the controlled by sensor 23 negative pressure to atmospheric pressure.
- a buffer bag can also be connected via the connection piece 25.
- a possible, not further shown embodiment is that a larger closed tank is connected via a connecting piece with the dehumidifier 9 of the expansion vessel 10 and a second smaller tank having a bottom and is arranged adjacent to the outer tank, so that a wall shared. In the shared wall, a pipe joint at a predetermined height is arranged in the lower area. An insulating liquid with predetermined filling volume is contained in both tanks, so that form a buffer space in the larger tank and a compensation space in the smaller tank. In the upper part of the jacket or in the lid of the smaller tank, a compensating tube is inserted, which is bent and open at the bottom.
- the method according to the invention can also be used with expansion vessels with separating membrane.
