Connecting device for transformer silicone respirator and breathing tube and method for replacing silicone

Abstract

The invention discloses a connection device for a silicone respirator and a breathing tube of a transformer, and a silicone replacement method of the connection device. The connection device comprises the silicone respirator, the breathing tube and an interlayer, wherein the silicone respirator comprises a glass container filled with silicone inside, a first flange is fixedly arranged at an end opening of the glass container, and a second flange is fixedly arranged at an end opening of the breathing tube; a through hole is formed in the middle of the interlayer, the interlayer is fixedly connected with the second flange, and the through hole is communicated with the breathing tube; first hook locks and second hook locks which are rotatable are connected with the peripheral wall of the first flange, lugs and locking screws are arranged on the peripheral wall of the interlayer, and the first flange and the interlayer are connected in a sealed, fixed and abutting manner by hooking the first hook locks on the lugs and hooking the second hook locks on the locking screws; the end opening of the glass container is communicated with the through hole, and the second hook locks are fastened or loosened by screwing in or screwing out of the locking screws. The connection device has the advantages as follows: mounting and dismounting are convenient and quick, and time and effort are saved.

Description

technical field [0001] The invention relates to a product for power production, in particular to a connection device between a transformer silicone respirator and a breathing tube and a method for replacing the silicone. Background technique [0002] In the power system, the transformer silicone breather is also a transformer moisture absorber, which is an accessory of the transformer. The transformer silicone breather is connected to the transformer's breathing tube by four screws. The respirator consists of a glass container equipped with blue silica gel as a hygroscopic material, which is used to absorb the moisture of the air entering the diaphragm of the transformer oil conservator capsule, eliminate and dry the air entering the oil conservator capsule due to the change of transformer oil temperature sundries and moisture, so as to prevent the transformer from getting damp and ensure the insulation strength of the transformer. Power grid operation and maintenance pers...

Problems solved by technology

This kind of operation method is time-consuming and labor-intensive. If the transformer is outdoors, the screws are prone to rust, which increases the difficulty of disassembly. The entire silicone replacement operation time is further prolonged, and the transformer’s non-gas protection operation time is increased, which reduces the reliability of power grid operation.
