technical field

The utility model belongs to the technical field of power transmission and distribution, in particular to a novel transformer respirator.

Background technique

As one of the main components of the transformer, the respirator plays the role of connecting the internal and external environment of the main transformer. In order to prevent the water vapor in the external air from entering the inside of the transformer, resulting in a decrease in insulation performance, silica gel is installed inside the respirator to absorb water vapor. When the discoloration of silica gel exceeds 2/3, it needs to be replaced in time to ensure the moisture absorption function.

At present, when replacing silica gel, it is necessary to protect the heavy gas of the transformer body first to prevent misoperation during the replacement process; then remove the oil seal cup, remove the connecting bolts of the respirator diagonally, place the respirator tank smoothly on a dry insulating pad, and use it immediately Block the connecting pipe of the respirator with a towel; then pour out the discolored silica gel in the tank, and replace the dry silica gel; finally, install the respirator according to the reverse process, and put in heavy gas to protect the pressure plate.

The process of replacing silicone with traditional respirators is cumbersome and time-consuming. During the replacement process, there are hidden dangers such as the failure of heavy gas protection to operate normally, damage to the respirator tank caused by bumps, and moisture in the air entering the transformer.

Description of drawings

Fig. 1 is a schematic cross-sectional structure diagram of an embodiment of the present invention.

Implementation

As shown in FIG. 1 , the novel transformer respirator disclosed in this embodiment includes a silicone barrel 1 , a shell 2 , an adapter pipe 3 , a filter screen 4 and a connecting screw 5 .

The silica gel barrel 1 is a glass cylinder, and the upper and lower ends of the silica gel barrel are provided with shells 2 to limit it up and down.

The shell 2 is disc-shaped stainless steel, and the diameter of the shell is slightly larger than that of the silica gel barrel. Four penetrating screw rods are evenly arranged between the upper and lower shells, and the two shells are clamped and fixed by nuts. The contact position between the shell and the silicone barrel is covered with a gasket.

The shell can protect the glass structure of the barrel when the respirator is placed on the ground.

There is a circular adapter at the corresponding position of the center of the top of the silicone barrel and the shell at the upper end, which is connected with the adapter pipe 3 . The transfer interface is a threaded opening, and the connection end of the transfer pipe is a threaded pipe, and the two can be conveniently and quickly connected and fixed through the thread.

There is a silicone inlet at the non-central position on the top of the silicone barrel and the corresponding position of the upper shell, and the inlet is closed with a gasket and a nut. Set the silica gel inlet to input dry silica gel.

A silica gel outlet is opened at the corresponding position of the center of the bottom end of the silica gel barrel and the shell of the lower end, and a filter screen 4 is arranged in the silica gel outlet. Set the silica gel outlet to discharge the discolored silica gel.

The diameter of the silica gel inlet in this embodiment is 1.5 cm, and the diameter of the silica gel outlet is 5 cm.

The filter screen 4 is a pull-out structure, the filter screen can be inserted into the silica gel outlet as a whole, and a through hole is opened in the center of the filter screen.

The connecting screw 5 is set at the transfer interface of the silica gel barrel 1 and the center of the silica gel outlet, the upper end passes through the top of the transfer pipe 3 and is tightened by the nut; the lower end of the connecting screw is inserted into the through hole of the filter screen, and passed through the ingot nut Fix the filter top firmly in the silicone outlet.

On the upper 1/5 of the barrel wall of the silicone barrel, mark with a laser, indicating that the silica gel should be installed to this height; on the lower part of the barrel wall of the silica gel barrel, mark with a laser at 2/3 of the height that the silica gel should be installed, indicating that the silica gel has changed color to this point should be replaced.

When the silica gel needs to be replaced, the filter screen of the silica gel outlet can be removed to discharge the discolored silica gel; after the silica gel outlet is closed, the sealing pad of the silica gel inlet can be removed, and the dry silica gel can be put into it.
