external fuel level gauge

2022-04-01

External fuel level gauge is a new component specially designed by Shenyang Transformer Research Institute for fully sealed distribution transformer. This product is safe.Installed on the fuel tank cover, it has the function of automatic exhaust and visually displays the fuel level. The fuel can be completely drained at the operating temperature

The gas in the tank can reduce the internal pressure of the tank and isolate the entry of external air, so as to avoid the contact between transformer fuel and air at high temperature.Reduce the aging speed of transformer fuel and prolong the service life of transformer. At the same time, the fully sealed distribution transformer equipped with exhaust fuel level gauge,

When filling fuel at normal temperature, a certain compensation space can be reserved under the tank cover. After operation, in the process of transformer fuel expansion, through this.The automatic exhaust function of the product makes the fuel tank full of fuel, which not only saves the amount of transformer fuel, but also relieves the transformer manufacturer. The trouble of repeatedly going to the site to replenish fuel. Pressure relief valve is a kind of pressure protection device, which is used to protect fuel immersed transformer, high-voltage switch, etc

The operation safety of the product. The protection procedure is that when the internal pressure exceeds the safety pressure of the fuel tank due to faults such as short circuit of electrical equipment,The release valve is quickly opened to quickly release the pressure inside the fuel tank, avoid deformation and fracture of the fuel tank and effectively protect the fuel tank. When in the fuel tank, When the partial pressure drops below the safety pressure of the fuel tank, the release valve can be closed automatically immediately to avoid external substances (such as air, water, etc.)Enter the interior of electrical equipment. The functions of exhaust and pressure relief valve can be selected individually. The installation dimensions are the same.
