A temperature-controlled switching maintenance-free moisture absorber with double drying chambers arranged longitudinally

Abstract

The invention relates to a temperature control switching maintenance-free moisture absorber with dual drying chambers longitudinally arranged. The temperature control switching maintenance-free moisture absorber comprises a first drying chamber, a second drying chamber, a lower flange, an intermediate flange and an upper flange, wherein the first drying chamber and the second drying chamber are sequentially arranged from bottom to top, the lower flange is arranged at a lower end of the first drying chamber, the intermediate flange is arranged between the two drying chambers, the upper flange is arranged at a top end of the second drying chamber, an air inlet and a total water outlet are respectively and independently arranged on the lower flange, a water guide and air inlet pipe and a first temperature control switching device are respectively arranged at a lower end of the intermediate flange, one end of the water guide and air inlet pipe communicates with the second drying chamber, the other end of the water guide and air inlet pipe penetrates through the first drying chamber to respectively communicate with the air inlet and the total water outlet, a breathing hole is formed in an upper end of the upper flange by an upper cover, a second temperature control switching device is arranged at the lower end of the upper flange, and the breathing hole communicates with a second breathing pipe arranged at the center of the second drying chamber by the second temperature control switching device and communicates with a first breathing pipe arranged at the center of the first drying chamber sequentially by a breathing connection pipe and the first temperature control switching device. By the temperature control switching maintenance-free moisture absorber, at least one of the drying chambers is enabled to operate.

Description

technical field [0001] The invention relates to a moisture absorber for a transformer oil conservator, in particular to a temperature-controlled switching and maintenance-free moisture absorber with double drying chambers arranged longitudinally. Background technique [0002] The transformer is a very important electrical equipment in the power system, and it is one of the important factors that determine whether the power system can supply power safely; and the transformer breather is a key component that determines the performance of the transformer, and its performance will directly affect the technical performance of the transformer . 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 or fully enclosed oil conservator, so that the breathing effect caused by the rise or fall of the oil level can keep the inside of the transformer in a normal pres...

Problems solved by technology

This will cause the possibility that hot and humid steam will be sucked into the transformer oil conservator when the silica gel is being heated and dehydrated, further threatening the reliable operation of the transformer

2. The air intake and outlet part of the maintenance-free dehumidifier adopts the structure of metal sintered mesh, which plays the role of filtering air dust, but the breathing state cannot be observed. At the same time, the existing maintenance-free dehumidifier is a channel due to the water and air channels. , so the oil cup arranged under the traditional dehumidifier cannot be installed, and the air inside and outside the device cannot be completely isolated

And there are still problems that the breathing state cannot be observed, and the air inside and outside the device cannot be isolated
