Description

Respirator of transformer

The present invention can easily check the respiratory action of the transformer, which is an electrical installation, and can extend the service life by preventing the discoloration of the silica gel by the insulating oil that is ejected, and the respirator of the transformer that is easy to disassemble and assemble during repair work. Relates to a device.

In general, the transformer 100 used in the electrical equipment, as shown in Figure 3, the transformer body 130, the radiator (120) installed on each of the left and right sides and the conservator in which the insulating oil is stored at a certain water level It is composed of a (conservator) 110, an important part in determining the state of the transformer 100 in operation is the insulating oil stored in the conservator 110, the oxidation of the insulating oil can be said to be fatal to the transformer (100).

The transformer 100 repeats the so-called breathing action in which external air is sucked into the inside or the inside air is discharged to the outside as the insulating oil is expanded or contracted by the temperature generated in the winding during operation and the ambient temperature in the open air. When the respiratory volume of the transformer 100 is large, it may be determined that an abnormality occurs in the transformer 100.

On the other hand, the conventional respirator 140 mounted on one end of the connection pipe 112 connected to the conservator 110 so that the breathing of the transformer 100 is smooth, as shown in Figure 4, the connection pipe An upper fixing plate 142 assembled as a lower end of the 112 and a plurality of screw members, a hollow transparent cylindrical body 144 filled with silica gel 143 for water removal, and the transparent cylindrical body 144. The upper and lower parts of the upper and lower fixing plate 142, 146 is fixed to the fixing stud 145 and the lower cap 148 is stored in the insulating oil is discharged due to excessive breathing of the transformer 100.

Accordingly, the air blown out from the inside of the transformer during the respiration of the transformer 100 passes through the inner space of the transparent cylindrical body 144 through the through hole 142a of the upper fixing plate 142 of the lower cap 148. Finally discharged to the outside through the through hole (148a), the air sucked into the transformer 100 is introduced into the transparent cylindrical body 144 through the through hole (148a) of the lower cap 148 is silica gel While passing through 143, water was removed to prevent oxidation of the insulating oil stored in the conservator 110.

However, when the insulating oil stored in the conservator 110 is blown into the transparent cylinder 144 through the connection pipe 112 together with the air inside during the ejection and respiration of the transformer 100, The silica gel 145 is contaminated by moisture removal, and the early discoloration of the silica gel 145 is further aggravated by the insulating oil flowing in and remaining in the lower gap 148. Accordingly, due to the discolored silica gel 145, the moisture in the air sucked in during the respiratory action of the transformer 100 is not completely removed, causing excessive moisture in the insulating oil stored in the transformer body 130, thereby oxidizing it early and discoloring. Due to frequent replacement of the silica gel 145, the work is very cumbersome, and there is a problem of lowering work productivity.

In addition, since it is impossible to check how the respiration of the transformer 100 is normally performed, the transformer 100 may be analyzed by performing analysis of the air ejected through the through hole 148a of the lower cap 148 using a separate device. The inspection time was excessively excessive, the equipment was operated in an unstable state, and during regular inspections every one year, the state of the insulating oil reached just before the burnout, and all the oil had to be lost, and the service life of the transformer was greatly reduced. There was a problem.

Therefore, the present invention is to solve such a conventional problem, its purpose is to easily check the operation state of the transformer in normal times, and to prevent the discoloration of silica gel for water removal can maintain the preservation state of the transformer for a long time In addition, the present invention aims to provide a respirator of a transformer that can reduce work load of workers and improve work productivity.
