Main transformer breathing moisture absorbing device with intelligent switching function and use method thereof

Abstract

The invention relates to a main transformer breathing moisture absorbing device with an intelligent switching function and a use method thereof. The device comprises a tee pipe, and a main pipe of the tee pipe is connected with a main transformer breathing pipe. A work electromagnetic valve is arranged on one branch pipe and connected with a work silicon gel tank, and a standby electromagnetic valve is arranged on the other branch pipe and connected with a standby silicon gel tank. Allochroic silicon gel is filled in the work silicon gel tank and the standby silicon gel tank. An automatic wavelength detector is arranged beside the work silicon gel tank, and an alarm is further arranged beside the work silicon gel tank. The work electromagnetic valve, the standby electromagnetic valve, the automatic wavelength detector and the alarm are all electrically connected with a control module. The device can switch to the standby silicon gel tank automatically according to change of allochroic silicon gel colors in the work silicon gel tank and alarm to remind working staff to replace the allochroic silicon gel timely. Main transformer breathing air flow sudden change is effectively prevented, a main transformer gas relay protection device is not required to be exited, moisture air is prevented from being inhaled, and safety operation of the main transformer is guaranteed.

Description

technical field [0001] The invention relates to a main transformer breathing moisture absorbing device with an intelligent switching function and a using method thereof. Background technique [0002] During operation, the main transformer will breathe with the outside air through the breathing tube. If there is no breathing hygroscopic device installed on the breathing tube, the main transformer will directly inhale the humid air from the outside. Especially in rainy and humid weather, the main transformer is more likely to be damp. When the hygroscopic packing of the traditional main transformer breathing hygroscopic device changes color and becomes saturated with moisture, it cannot automatically switch and alarm, and the staff needs to observe on site before notifying professionals to come and replace it, and the main transformer breathing tube is directly connected to the outside atmosphere during the replacement process , will cause changes in the main transformer breat...

AI Technical Summary

Problems solved by technology

[0003] The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a main transformer breathing moisture absorbing device with an intelligent switching function and its use method, which solves the problem of the traditional main transformer breathing moisture absorbing device. It cannot be switched automatically and needs heavy tiles to withdraw from the protection during replacement, so there are safety hazards and other problems. It overcomes the problem that the breathing tube of the main transformer is directly connected with the outside atmosphere when the silicone tank is removed, so that the breathing airflow of the main transformer directly inhales the external moisture and moisture, resulting in moisture. defect
