Intelligent dynamic sealed liquid storage tank equipped with metal ripple compensator and use method of intelligent dynamic sealed liquid storage tank

Abstract

The invention relates to an intelligent dynamic sealed liquid storage tank equipped with a metal ripple compensator and a use method of the intelligent dynamic sealed liquid storage tank. A liquid inlet solenoid valve is arranged at the liquid inlet of the liquid storage tank; a discharge valve is arranged at the discharge opening; a liquid outlet solenoid valve and an on-line moisture detection instrument are sequentially arranged at the liquid outlet of the liquid storage tank in the liquid outlet direction; the metal ripple compensator is mounted inside the liquid storage tank; wheels are mounted at the bottom of the metal ripple compensator; a guide rail matched with the wheels are mounted in the liquid storage tank; a breathing tube communicated with the metal ripple compensator is arranged at one end of the liquid storage tank; an electric contact liquid level meter is arranged at the other end of the liquid storage tank; the liquid inlet solenoid valve, the liquid outlet solenoid valve, the on-line moisture detection instrument and the electric contact liquid level meter are electrically connected with a control module. According to the invention, the cavity of the metal ripple compensator is communicated with the outer atmosphere through the breathing tube; the breathing action of the metal ripple compensator can perform the functions of compensating and balancing volume change in the liquid storage tank. caused by change in liquid level, so as to achieve dynamic sealing.

Description

technical field [0001] The invention relates to an intelligent dynamic sealed liquid storage tank with a metal corrugated compensator and a using method thereof. Background technique [0002] The physical and chemical properties of transformer oil are relatively stable at normal temperature and pressure, and the density is about 0.86 (there will be slight differences between different origins and different oil types). The electrical performance and physical and chemical properties of oil have a great influence, and the existence of water in oil also aggravates the deterioration of oil. Transformer oil is prone to moisture, especially in rainy season or humid weather. If the seal is not good, dozens of tons of oil will be damp in a few days and need to be reprocessed before use. Therefore, a sealing method is adopted to prevent the intrusion of moisture, moisture, air, impurities, etc. It is the most important factor to ensure the quality of transformer oil storage. The tra...

Problems solved by technology

This storage method is the most common at present. Using this storage method is better than the first method, but it cannot be isolated from the air, and the hygroscopic packing saturated with moisture absorption needs to be replaced frequently.

[0005] The third type is storage in small oil barrels: 170kg standard barrels of transformer oil or other similar small oil barrels are usually sealed by tightening the gland, but the operation is cumbersome and time-consuming when adding and draining oil and handling a large amount of oil. And the labor intensity is high. At this time, the oil product is in contact with the outside air, which is easy to be affected by moisture, and it is easy to cause environmental pollution such as leakage, leakage, etc.

[0006] The above traditional storage methods of transformer oil do not have dynamic sealing function, and cannot isolate air and moisture during work, and cannot guarantee the quality of stored oil for a long time, safely and reliably
