Silica gel packing device for transformer breathing devices

Abstract

The invention discloses a silica gel packing device for transformer breathing devices. The silica gel packing device comprises a loading part with the funnel-shaped lower portion, and a fixing part inserted into the lower end of the loading part. The cross section of the fixing part is round. Four sliding grooves are uniformly distributed in the fixing part and are of a radial shape with the circle center of the fixing part as the center. A fixing rod is arranged in each sliding groove. The fixing part further comprises an elastic ring making contact with the inner side of each fixing rod to exert thrust, away from the direction of the circle center, on the fixing rods. The fixing part further comprises an elastic hoop making contact with the outer side of each fixing rod to exert the thrust, in the direction of the circle center, on the fixing rods. The silica gel packing device has the advantages that the structure is simple, in the silica gel filling process, the position of the silica gel packing device can be well fixed, loosening is not easy, the silica gel packing device can be suitable for the various transformer breathing devices of different sizes, the silica gel packing speed is increased, the adoption of the method of mouth-to-mouth pouring is avoided, manual control is not needed in the packing process, silica gel will not be scattered, and therefore waste of resources is avoided.

Description

[0001] The patent application of the present invention is a divisional application of the invention patent named "Silicone filling device for transformer respirator". The application date of the original application is January 28, 2014, and the application number is 2014100411225. technical field [0002] The invention relates to a silica gel filling device for a transformer respirator. Background technique [0003] Since the temperature of the transformer will change at any time during operation, the oil level inside the transformer will rise or fall. The oil conservator is a semi-enclosed oil conservator or a fully enclosed oil conservator, so that the inside of the transformer can maintain a normal pressure state due to the rise or fall of the oil level. Therefore, in order to slow down the deterioration of the transformer oil and prevent air from affecting the insulation For oil pollution, install a respirator on the oil exhalation channel. The respirator is also called...
