Description

Deffeuchfunqsvorrichfunq for a transformer

The invention relates to a humidification device for a transformer, with a container for receiving an absorption medium for absorbing a liquid contained in a gas, in particular air, in particular water, the container having a base and a shell side having a front opening. The invention also relates to a system with such a dehumidifying device and a transformer.

Self-regenerating air dehumidifiers are known from the prior art, in which the air is dehumidified which is sucked in by the falling oil level in an oil-filled container of a transformer. These air dehumidifiers are mainly used on equipment filled with insulating oil, such as power transformers and coils. To dehumidify the air, a moisture-absorbing granulate is used in the air dehumidifier, to which the moisture in the air binds. The binding of the water molecules to the granulate is reversible and is broken down again in these devices with implemented heating elements so that the granulate does not have to be replaced. The self-regenerating air dehumidifiers replace conventional air dehumidifiers in which the moisture-absorbing granulate has to be replaced when it is saturated.

With conventional air dehumidifiers, an absorbent, for example moisture-absorbing granules, is usually used, which is provided with a color indicator to show the saturation of the granules. This indication is not possible with the self-regenerating air dehumidifiers. With these devices, the air exchange takes place over the surface of the cylindrical granulate container. Such a structure is disclosed in US Pat. No. 5,902,381.

The outer surface of most air dehumidifiers is visible, but there are only two states when granules with a color indicator are used, namely the granules are unsaturated or saturated. In practice, there is only one state in which the granulate appears saturated, since the outer surface area is quickly saturated again even after regeneration and the color is therefore changed. The condition of the granulate inside the cylinder cannot be seen. The operator has no option to be able to assess the condition of the granulate and the amount of unsaturated and not handled granulate by means of a visual control.

The object of the invention is therefore to provide a dehumidifying device in which the amount of unsaturated and unused absorption media can be assessed in a simple manner.

The object is achieved by a dehumidifying device of the type mentioned at the outset, which is characterized in that the end face opening and an outlet channel are arranged in such a way that when the transformer is sucked in, the gas can be introduced into the container via the end face opening and that that which is dehumidified in the container Gas can be discharged from the container in the direction of the transformer via an outlet channel of the dehumidifying device that is fluidically downstream of the end face opening.

In the case of the dehumidifying device according to the invention, there is an advantage that the gas path through the absorption medium is guided along the outer surface via the front opening of the container. This ensures that the absorption medium turns slowly from the front opening in the direction of the bottom of the container. The absorption medium arranged in a plane which is perpendicular to the outlet channel and / or the central axis of the container turns over. In particular, the absorbent is turned over along the center axis of the container. Thus, during a dehumidification process, the dehumidifying device has two sections along the central axis, namely a section with saturated absorbent and another section with unsaturated absorbent. During the dehumidification process, the section with saturated absorption medium increases successively starting from the front opening in the direction of the floor along the central axis.

In contrast to the dehumidifying device known from the prior art, in the embodiment according to the invention the absorption medium is no longer acted upon by the gas along the entire surface area and thus no longer overturns along the entire surface area. In addition, in the embodiment according to the invention, the turning is no longer carried out in a direction transverse to the central axis of the container, but rather along the central axis. As a result, the de-humidifying device according to the invention enables the state of the absorption medium to be determined more easily than in the case of the dehumidifying devices known from the prior art.

The gas can be air and the liquid can be water. The air may contain an unacceptable amount of liquid for the transformer and must therefore be dehumidified before entering the transformer.

The absorbent can be a moisture-absorbing granulate that works according to the following chemical-physical principle. The air and thus the water molecules flow past the absorbent. The water molecules are either bound to the surface of the absorbent by their bipolar character or they penetrate the absorbent by capillary condensation. At higher flow velocities, a longer distance of the air is required through the absorbent until practically all water molecules are bound.

On the basis of the above principle, the absorbent arranged in the container can be divided into three zones along the direction of flow. A first zone comprises saturated absorbent and no further liquid molecules can be bound there. This zone becomes longer as the operating time continues and is eliminated again after a regeneration process. A second zone is the active zone. Dehumidification takes place in this zone. The length of this zone depends mainly on the flow rate and the absolute amount of liquid molecules in the gas. After this zone comes the reserve zone with unsaturated absorbent.

The dehumidifying device according to the invention is also distinguished by the fact that there is a significantly larger reserve for the active zone due to the significantly longer gas path along the outer surface of the container compared to the known designs. This ensures in a simple manner that the active zone plus the reserve zone is sufficient and there is no risk of incompletely dehumidified gas from the dehumidifying device entering the transformer because the active zone is too short. This can be done with those known from the prior art Humidification devices occur when the gas contains a large amount of liquid.

As described above, the introduction of the gas via the end face opening has the effect that the upper area, that is to say the area facing away from the bottom of the container, is saturated with the absorption medium. This offers the advantage that if the regeneration process is aborted, in which there is an absorption gas laden with moisture in the container †, the absorption gas can be prevented from reaching the transformer †.

In the case of dehumidification from the ground upwards used in the known dehumidifying devices, there is the problem that the thermals also cause the moisture to rise from the bottom upwards † in order to then reach a point where there is access to the transformer †. Because of this, there is always the risk of moist gas entering the transformer if the conditions change.

Furthermore, it is very likely that in the known dehumidifying devices a color indicator moves from bottom to top and a color indicator is obtained according to which the absorption medium is unsaturated in the lower range and is saturated in the middle or upper range. With the known dehumidifying devices, a regeneration process cannot be interrupted if an operating state of the transformer has changed †, because otherwise the undesired state described above is set †.

The front opening is designed † so that the gas to be dehumidified can flow into the container. The front opening and the bottom of the container are arranged at the ends of the shell side and / or are opposite one another with respect to the shell side.

In a particular embodiment, the outlet channel can be arranged coaxially to the center axis of the container †. The outlet channel can extend through the end face opening. In particular, the outlet channel can be fluidically connected to a valve device described in more detail below, in particular directly. An outlet channel inlet opening can be arranged between the floor and the forehead soap opening. In particular, the outlet inlet opening can be arranged in the vicinity of the bottom of the container. The outlet channel inlet opening can be arranged in a region of the interior space enclosed by the soap of the container. The dehumidified gas flows † from the interior of the container through the outlet channel inlet opening into the outlet channel and flows from there in the direction of the transformer.

In at least one section of the container, a direction of flow of the gas to be dehumidified can be opposite to a direction of flow of the dehumidified gas in the outlet channel. In this way, a particularly compact dehumidifying device can be implemented in a simple manner †.

A flow path of the gas to be dehumidified between the end face opening and the outlet channel can be longer than a radial distance between the outlet channel and the shell side. This ensures in a simple manner † that the gas flowing into the outlet duct does not have any moisture † or that the moisture content is in a range that is acceptable for the transformer.

The container can be cylindrical †. The absorption medium can be arranged in an interior of the container. The absorption medium is not arranged in the outlet channel.

In a special embodiment, the shell side can be transparent or partially transparent. This makes it particularly easy to check the condition of the aborotion medium. The check can be carried out manually, ie visually, by a user. Alternatively, the check can be carried out automatically. For this purpose, there can be a detection device that detects the state of the absorbent †. The detection device can detect an optical sensor and / or a camera. In particular, the detection device can detect a color change of the absorbent. If the saturation amount of the absorbent exceeds a critical value, a regeneration process described in more detail below can be initiated. The dehumidifying device can have a heating device for heating the absorption medium and / or the interior of the container. The absorption medium can be heated to 120 ° -140 ° C (Celsius) through the heating device. As a result, the binding of the liquid in the absorption medium is broken and the moisture can be absorbed by the surrounding gas and / or an absorption gas described in more detail below. The heating device can be arranged in the interior of the container. The heating device can be designed in such a way that it uniformly heats the absorption medium arranged in the interior of the container. In addition, the heating device can be designed such that it divides the interior of the container into several sections †.

The dehumidifying device can have a locking plate with perforations to close off the front opening †. This is a simple way of preventing absorption media from falling out of the container when the de-humidifying device is being transported.

In addition, the dehumidifying device can have a cover. The lid can be arranged and designed such that an opening is formed between the lid and the container through which the gas to be dehumidified can flow into the dehumidifying device. In addition, the cover can cover the front-side opening, in particular completely, and / or is arranged at a distance from the front-side opening. The cover can be arranged at a distance † from the end face opening † in such a way that a cavity is formed between the end face opening and the cover †.

The lid can be inclined at an angle. In particular, starting from the central axis of the container, the lid can drop in a direction transverse, in particular perpendicular, to the central axis. The cover can fall off in the direction of the shell side. Such a design of the cover has advantages, especially during the regeneration process of the dehumidifying device, as will be explained in more detail below.

For example, during a regeneration process, an absorption gas is supplied to the absorption medium in order to absorb the moisture in the absorption medium, in particular the water absorb. For this purpose, the absorbent is heated by means of the heating device. The heated air rises, so that a negative pressure develops in the interior †, due to which the absorption gas flows into the container †. The absorption gas that has flowed in absorbs the liquid bound by the absorption medium. After the regeneration process, the absorption medium is ideally no longer saturated with liquid and is thus available again for a dehumidification operation in which the gas supplied to the transformer is dehumidified. In the case of the dehumidifying device according to the invention, the absorption gas, which is saturated with liquid, can be led directly out of the device during the regeneration process.

The sloping lid has the advantage that in the event that the liquid absorbed by the absorption gas should condense on the lid, the moisture can be led out of the dehumidifying device due to the sloping and / or a drip edge. As a result, it is prevented in a simple manner that the absorption medium is not preloaded by the condensed liquid.

In one embodiment, the dehumidifying device can have a first valve, by means of which the outlet channel or a floor opening can be closed as desired.

In an independent aspect of the invention, a dehumidifying device for a transformer can be present, with a container for receiving an absorbent for absorbing a liquid contained in a gas, in particular Lut †, in particular water, the container having a bottom and a Shell side having an end face opening †, which is characterized by a first valve by means of which the outlet channel or a bottom opening can be closed.

Providing the valve offers the advantage that it is particularly easy to switch between the dehumidification process, in which the gas supplied to the transformer is dehumidified, and the regeneration process described above. During the dehumidification process, the first valve can thus close the opening in the floor and not close the outlet channel, in particular the outlet channel opening. The valve can be used as an electrically controllable Valve. As a result, the regeneration process can be initiated automatically in a simple manner, for example by a control device.

During the regeneration process, the first valve can close the outlet channel and not close the floor opening. As already described above, during the regeneration process, an absorption gas can be introduced into the container through the floor breakthrough in order to absorb the liquid contained in the absorption medium.

The absorption gas introduced into the container can be released from the container through the front opening †. In particular, the absorption gas introduced into the container can be released from the dehumidifying device through the opening †. This means † that the gas fed into the dehumidifying device during a dehumidifying process and the absorption gas discharged from the dehumidifying device during a regeneration process through the same opening. This allows a simple construction of the dehumidifying device to be realized.

The dehumidifying device can have a humidity sensor for determining the humidity in the absorption medium. In addition, the dehumidifying device can have a determination device for determining a color change of the absorbent. The determination device can comprise a camera by means of which at least one image of the absorbent is captured. The captured image can be examined in the control device with regard to the color change †. Depending on the results of the examination, further measures, such as the regeneration process, can be initiated †.

In one embodiment, the dehumidifying device can have a valve device. The valve device can be fluidically connected to the outlet channel. In addition, the valve device can be fluidically downstream of the outlet channel †.

In an independent aspect of the invention, a dehumidifying device for a transformer can be present, with a container for receiving an absorption medium for absorbing a liquid contained in a gas, in particular air, in particular water, the container having a base and a shell side having an end face opening †, which is characterized by a valve device which is fluidically connected to the outlet channel and / or which is † downstream of the outlet duct in terms of flow.

The valve device can be designed and intended such that it enables a gas flow from the outlet duct to the transformer when the transformer is sucked in. During the suction process, a gas flow is brought about from the dehumidifying device to the transformer. In this case, a dehumidifying process must therefore be carried out in the dehumidifying device in order to prevent moist gas from getting into the transformer.

An output process can also be carried out via the transformer. During the dispensing process, there is a gas flow from the transformer to the dehumidifying device. The valve device can be designed and intended in such a way that it prevents a gas flow from the transformer to the container during the discharge process of the transformer. In this way it can be prevented in a simple manner that, for example, air laden with oil can flow from the transformer into the container. This is disadvantageous in that the absorbent would take up the oil. However, absorbent saturated with oil cannot be regenerated, so that the absorbent is lost for absorption in future dehumidification processes and must be replaced.

The valve device can have a second valve and a third valve. The second and third valve can work in opposite directions. In this case, the second valve can prevent a gas flow from the outlet duct to the transformer in a closed position and enable a gas flow from the outlet duct to the transformer in an open position. In a closed position, the third valve can prevent a gas flow from the transformer into an area outside the dehumidifying device, and in an open position a gas flow from the transformer into the area outside the dehumidifying device enable. The valve device, in particular the second and third valve, can be controlled electrically, for example by monitoring electronics.

When the transformer is sucked in, the second valve can be in the open position and the third valve in the closed position †. During the output process of the transformer, the second valve can be in the closed position and the third valve in the open position †. In addition, the second valve can be in the closed position and the third valve in the closed position when there is neither a suction process nor a discharge process †.

As a result, the dehumidified gas can be fed in in a simple manner during a suction process of the transformer † and a gas flow can be prevented from occurring in the container of the dehumidifying device during a discharge process of the transformer †.

A system with a transformer and a dehumidifying device according to the invention, which is characterized in that the dehumidifying device is fluidically connected to the transformer, is particularly advantageous. In addition, the dehumidifying device, in particular the valve device, can be mechanically connected to the transformer.

In the figures, the subject matter of the invention is shown schematically, with elements that are the same or have the same effect, mostly with the same reference symbols. Show †:

Fig. 4 shows a system that has the dehumidifier and the transformer †. 5 shows a valve device of the dehumidifying device,

A humidification device 1 shown in FIG. 1 has a container 3. The container 3 serves to hold absorbent material 4. The absorbent medium 4 can be moisture-absorbent granules which are arranged in an interior 10 of the container 3. The container 3 is cylindrical † and has † a base 5 and a shell side 7. The shell side 7 has an end face opening 6 at the end facing away from the base 5.

The end face opening 6 is arranged in such a way that, during a suction process shown in FIG. 1 of a transformer 2 shown in FIG. 4, a gas G1 to be dehumidified via the end face opening 6 into the container 3, in particular the interior space filled with absorption medium 4 10 of the container 3 inflow †. The dehumidified gas Gl is erupted through an outlet channel 8 from the container 3 in the direction of the transformer 2 †. In this case, the outlet channel 8 is downstream of the face opening 6 in terms of flow †.

The container 3 is designed † so that a flow path between the end face opening 6 and an outlet channel inlet opening 9 is longer than a radial distance between a central axis M of the container 3 and the shell side 7. The outlet channel 8 is arranged coaxially to the central axis M †. The central axis M runs coaxially to the central axis M of the container 3.

One end of the outlet channel 8 having the outlet channel opening 9 is arranged in a region of the interior 10 of the container 3 which has no absorption agent 4. This area can be separated from the rest of the area of the interior 10, which contains absorption media 4, for example by a mesh belt 19 provided with mi † holes. The outlet channel 8 extends on its side facing away from the outlet channel opening 9 through the end face opening 6 and is fluidically connected to a valve device 16 of the dehumidifying device 1.

The dehumidifying device 1 also has a closing plate 20 for partially closing off the end face opening 6. The locking plate 20 has a variety of Holes through which the gas to be dehumidified can flow into the interior of the container 4. The closure plate 20 prevents the absorbent 4 located in the interior space 10 from falling out of the container 3 during transport.

The dehumidifying device 1 also has a cover 12. The cover 12 is inclined. In particular, the cover 12, starting from the central axis M, drops in the radial direction in the direction of the casing side 7. The cover 12 closes the end face opening 6 completely. The cover 12 is designed such that there is a cavity between the cover 12 and the end face opening 6. In addition, the lid 12 is designed and arranged in such a way that an opening 13 is formed between the lid 12 and the container 3 †.

During the suction process of the transformer shown in FIG. 1, moist gas Gl is introduced into the cavity through opening 13 †. The moist gas G1 flows out of the cavity through the front opening 6 into the interior 10 of the container 3. Since the absorbent 4 is arranged in the interior 10, the introduced gas Gl is dehumidified as it flows through the interior 10. The dehumidified gas Gl flows through the outlet channel opening 9 into the outlet channel 8 and flows in the direction of the transformer 2. The flow direction of the gas to be dehumidified in a large part of the section of the interior space 10 is opposite to the flow direction of the dehumidified gas Gl in the outlet channel 8 The direction of flow of the gas Gl is shown in FIG. In this case, the gas G 1 still to be dehumidified is regarded as the gas that has not yet flowed into the outlet channel 8. The gas Gl flowing in the outlet channel 8 is referred to as dehumidified gas Gl.

The dehumidifying device 1 also has a first valve 14. In the position shown in FIG. 1, the first valve 14 closes a floor opening 15. In addition, the first valve 14 is designed in such a way that it does not close the outlet channel opening 9. Such a valve position enables the above-described dehumidification process, in which the gas G1 sucked in via the opening 13 is dehumidified by the absorption means 4 before it is fed to the transformer 2. The first valve 14 can be moved along the central axis M of the container 3, which is illustrated by the double arrow. In addition to the absorbent 4, a heating device 11 shown in FIG. 3 is arranged in the interior 10. The heating device 1 1 serves to warm up the absorption medium 4. During the de-humidification process, the heating device is disconnected and therefore does not heat the absorption medium 4.

FIG. 2 shows the dehumidifying device 1 shown in FIG. 1 during a regeneration process. During the regeneration process, the first valve 14 is adjusted in such a way that it closes the outlet channel opening 9 and opens the floor passage. During the regeneration process, the heating device 11 is switched on, so that the absorption medium 4 is heated. In addition, the gas located in the interior 10 is heated †, which leads to the gas figing open. As a result of the negative pressure thus created in the interior 10, an absorption gas G2 flows into the interior 10. The absorption gas G2 can also be Lut †. Thereby † offers the cold air † as absorption gas † is used.

As can be seen from the flow profile shown in FIG. 2, the absorption gas G2 flows through the floor passage 15 into the interior 10 of the container 3. In particular, the absorption gas G2 flows into the area of the interior 10 in which no absorption medium 4 is arranged.

From there, the gas flows through the remaining part of the interior 10 containing the absorption medium 4. The absorption gas absorbs the liquid located in the absorption medium 4. The moist absorption medium 4 leaves the container 3 via the front opening 6. Subsequently, the moist absorption medium 4 flows out of the dehumidifying device 1 via the opening 13.

FIG. 3 shows the heating device 11 which is installed in the dehumidifying device 1 shown in FIGS. 1 and 2. The heating device 11 essentially has a cylindrical outer contour. The heating device 11 is designed in such a way that it can be inserted into the interior 10 of the container 3.

In addition, the heating device 11 is designed in such a way that it separates the interior 10 of the container 3 into three or more heating spaces 21. That is not shown in FIG Absorbent 4 is arranged in the heating rooms 21. The heating device 1 1 is arranged coaxially to the outlet channel 8.

Fig. 4 shows a system that has the dehumidifying device 1 and the transformer 2 †. The dehumidifying device 1 is fluidically connected to the transformer 2. The transformer 2 has an oil container that is partially filled with oil 24. In addition, a gas, especially Lut †, is contained in the oil container. As indicated by the double arrow †, an oil level in the oil container is variable.

Two states can occur during the operation of the transformer. Thus, during a suction process, the oil level in the oil container 20 can drop, which leads to a negative pressure in the oil container 20. The negative pressure causes the moist gas Gl to be sucked into the dehumidifying device 1 and dehumidified there. The dehumidified gas Gl flows into the oil container 20.

During an output process of the transformer 2, the oil level in the oil container 20 rises. As a result, there is an overpressure in the oil container 20, which leads to a gas flow from the oil container 20 to the humidification device 1. Overpressure and underpressure relate to the atmospheric pressure.

Figure 5 shows the Venfileinrichfung 16 of the humidification device in detail. The valve device 16 has a second valve 17 and a third valve 18. In this case, the valve device 16 is fluidically arranged between the outlet channel 8 shown in FIG. 1 and the oil container 22 shown in FIG.

In the position shown in FIG. 5, there is no gas flow from the humidification device 1 to the transformer 2 or vice versa. Thus, the transformer 2 does not perform a suction process or a discharge process †. The second and third valve 17, 18 are both in the closed position.

During a suction process, the negative pressure from the oil container 22 acts in a valve interior 23. The negative pressure causes the second valve 17 to move from the closed position into an open position (not shown), in particular in the vertical direction. In the open position, the dehumidified gas can be released from the The outlet channel 8 flows into the valve interior 23 and from there to the oil container 22. During the suction process of the transformer 2, the third valve 18 remains in the closed position. During an output process of the transformer 2, the overpressure of the oil container 22 acts on the valve interior 23. The overpressure causes the third valve 18 to move from the closed position to an open position, in particular in the horizontal direction †. When the third valve 18 is in the open position, the gas flowing out of the oil container 22 can be released from the dehumidifying device 1 into the environment. The second valve 17 remains in the closed position during the dispensing process.
