What is a transformer oil level meter

transformersoil level meterIt is an important instrument used for real-time monitoring and displaying the level of insulating oil in the transformer tank, the following is its specific introduction:
Working Principle
Common oil level gauges visualize the oil level by means of the connecting tube principle or float indication. When the oil level inside the transformer changes, the oil level in the connecting tube also changes, which in turn drives the corresponding displacement of the indicating part of the oil level gauge, thus showing the current oil level externally.
functional role
Insulation and cooling: Insulating oil is the main insulating medium of the transformer, and the oil level gauge ensures that the oil level is in the right range, thus ensuring the insulation and cooling effect of the transformer and preventing overheating and degradation of insulation due to abnormal oil level.
Monitoring operation status : Help operation and maintenance personnel to discover oil leakage, oil seepage and other problems inside the transformer in time, so as to avoid further expansion of the fault. At the same time, the oil level changes can also assist in determining the load condition of the transformer, so as to adjust the operation strategy in time.
Provide maintenance reference: Provide important reference basis for transformer overhaul and maintenance, so that the operation and maintenance personnel can reasonably arrange the maintenance plan according to the oil level, and improve the reliability and service life of the equipment.
Classification and Characteristics
Pointer-type oil level gauge: through the linkage mechanism will float up and down float into the pointer on the dial rotation, so as to indicate the oil level. Its advantages are simple structure, low cost, intuitive and easy to read, but the accuracy is relatively low, and need to be observed in close proximity.
Tube oil level meter: mainly applicable to oil-immersed sealed transformer, installed in the upper part of the transformer tank cover. Through the buoy indication device shows the oil level, the oil level is normal when the window appears blue labeling, the oil level is abnormal when the red labeling. It can show the lower part of the box cover within a certain range of specific oil level, display true and accurate, no false oil level phenomenon.
Electronic Oil Level Gauge: A revolutionary version of the traditional oil level gauge, the oil level can be continuously monitored remotely, with the operator able to remotely monitor a preset value or read the value from an electronic digital display panel mounted on the transformer wall. The digital interface allows easy connection to smart grid applications and integration into the system for intelligent monitoring. Its alarm and trip parameters can be customized, and it is maintenance-free and easy to install.

Which is the best transformer oil level meter manufacturer

Points of choice

• Qualification and Reputation Priority is given to manufacturers that have been established for a long time and have a good reputation in the power industry, and check whether they have relevant production qualifications and certifications, such as ISO quality management system certification.
• technical strength : Examine whether the manufacturer has a professional R & D team and advanced production equipment, and whether it can continue to introduce innovative products, such as intelligent oil level meter.
• product quality : Concerned about the material, process, sealing, measurement accuracy and other quality indicators of the oil level gauge, require manufacturers to provide product inspection reports, test data, etc., to ensure that the product can operate stably in harsh environments.
• Service : Understand the manufacturer's after-sales service system, including the distribution of after-sales outlets, response time, warranty period, technical support, etc., to ensure that problems encountered in the use of the process can be resolved in a timely manner.
