Paunsa nimo buhaton ang oil-immersed transformer isip fire protection device?

Protection Devices：
Gas Relay：

Kon adunay fault sa dako sa transformer sama sa local overheating, electric arc discharge, etc., ang insulating oil will decompose and produce gas. Ang gas relay is installed in the connecting pipeline between the oil tank and the conservator of the oil - immersed transformer.
Once a certain amount of gas is detected, the gas relay will act. It can take different measures according to the severity of the fault. For example, when the light - gas action occurs, an alarm signal will be sent to remind the operation personnel to check; when the heavy - gas action occurs, the power supply of the transformer will be directly cut off to prevent the fault from further expanding and causing a fire.

Fire Isolation Measures：
In the installation environment of the transformer, fire isolation facilities are usually set up. For example, in a substation, an oil - immersed transformer may be installed in an independent fire - proof compartment.
The fire - proof compartment is constructed with fire - resistant materials, such as fire - bricks, fire - proof coatings, etc. These materials can prevent the spread of fire for a certain period of time (such as 1 - 2 hours, depending on the material properties), buying time for firefighters to come and put out the fire.
In addition, fire - proof dikes may be set up around the transformer to prevent the large - area fire caused by the outflow of insulating oil after the rupture of the transformer's oil tank. The fire - proof dikes can limit the leaked oil within a certain range.
