Transformer protection device is composed of several parts such as oil storage tank. ¢Ù Oil storage tank. Also called oil pillow or oil expander, it is mainly used to reduce the contact area between transformer oil and air, reduce oil moisture and   The degree of oxidation   slows down the deterioration of the oil and extends the service life of the transformer oil. At the same time, it provides buffer space for transformer oil with changes in temperature and load.

¢Ú Dehumidifier. Built-in hygroscopic agent, such as color-changing silica gel, can absorb the moisture entering the oil storage tank. Ensure that the transformer oil does not deteriorate.

¢Û Safety airway. Also called explosion-proof tube. When a fault occurs in the transformer, such as   short circuit  , etc., The insulating oil burns and rapidly decomposes into gas, which causes a sudden increase in the internal pressure of the transformer. The oil and gas will blow through the glass membrane of the explosion-proof pipe to release the pressure to prevent the transformer oil tank from breaking.

¢Ü Gas   Relay  . Also called a gas relay. Gas relays are an important protective component of transformers. When a fault occurs inside the transformer tank (such as insulation   breakdown  , When winding turns or layers are short-circuited, etc.) When gas is generated or the oil level of the transformer tank is lowered, the gas relay is activated, and an alarm signal (light gas) is issued or the relay protection circuit is connected to enable www.hqchip.com/app/848 'target =' _ blank 'class =' arckwlink_hide '> Switch   Trip (heavy gas) to ensure that the fault is no longer expanding to protect the transformer. In addition, after a fault occurs, you can observe the gas color through the window of the gas relay, and take the gas for analysis, so as to make a judgment on the nature of the fault.

¢Ý Oil purifier. Also called thermosiphon or thermal oil filter. Filled with adsorbent. When the transformer oil flows through the adsorbent, the moisture in the oil and the free acids that accelerate the aging of the oil are absorbed. To achieve the purpose of continuous purification of transformer oil.

¢ÞTemperature measuring device. Used to measure transformer oil spills.

Transformer protection device is a power automation product that integrates multiple functions such as protection, monitoring, control, and communication. It is a physical and electrical unit that forms an intelligent switch cabinet. This product has a built-in protection library composed of more than twenty standard protection programs, with a primary device voltage   Current   Complete and powerful acquisition function of analog and switching value (current measurement is realized by protection CT).

The transformer uses the function of film protection: it can seal the transformer without contact with air. Thereby eliminating the oxidation of the oil and slowing down the aging rate of the oil.
