Product Description Transformer Oil Level Gauge: A Vital Guardian for Safe OperationA Transformer Oil Level Gauge, or Oil Sight Glass, is an essential monitoring device installed on the conservator (expansion tank) of oil-immersed transformers. Its primary function is to provide a clear and continuous visual indication of the insulating oil level inside the transformer.Maintaining the correct oil level is critical for the transformer's safety, reliability, and longevity. The oil serves as both an insulator and a coolant. An abnormal oil level can signal potential issues or lead to severe consequences:Low Oil Level: Can expose live parts, leading to inadequate insulation, potential electrical faults, and dangerous overheating due to reduced cooling capacity.High Oil Level: May be caused by excessive internal pressure or overfilling, risking oil leakage and putting mechanical stress on the tank.Key Features and Components:Clear Visual Indicator: Typically features a graduated sight glass (with MAX/MIN markings) for easy reading of the oil level under normal operating conditions.Magnetic Operation: Many modern gauges use a magnetic coupling mechanism. This hermetically seals the internal oil from the external indicator, preventing leaks and contamination while ensuring accurate readings.Alarm Contacts: Equipped with integrated switches (float-type or magnetic) that can be connected to the control system. They automatically trigger remote alarms-both for low-level and high-level conditions-alerting operators to take immediate action.Robust Construction: Built to withstand harsh outdoor environments, including wide temperature variations, weather exposure, and vibrations.In summary, the oil level gauge acts as the "eyes" for the transformer, enabling proactive maintenance and preventing catastrophic failures. It is a fundamental component for ensuring the operational safety and health of power transformers.Product ParametersGASKET(31*45*3)NBR 70SET SCREWSTAINLESS STEELO-RINGNBR 70WASHERBRASSFLOATROHACELLHANDLE FOR FLOADALUMINIUMWASHER PLASTIC
