Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, and more specifically, particularly to an insertion type oil level monitoring device. Background Art

[0002] The power transformer is an important component of the power system and one of the most core equipment in the power system. It plays an important role in voltage conversion and electric energy distribution. As an important equipment in the power supply and transformation line, the normal operation of the power transformer is an important guarantee for the safe and reliable operation of the power system. Therefore, monitoring and diagnosis of the operating status of the power transformer is an indispensable task to ensure the normal operation of the power supply network, which can effectively avoid safety accidents caused by safety hazards.

[0003] For oil-filled transformers among power transformers, oil leakage and low oil level are one of the main causes of damage to this type of transformer. Due to the dense distribution of power transformers, it is impossible to implement round-the-clock manual monitoring of the operating conditions. When the oil level is too low, it will affect the operation of the transformer, resulting in unreliable power supply quality; especially for some large transformers, due to their large capacity and high voltage, manual monitoring is very inconvenient.

[0004] During the operation of the transformer, effective fault diagnosis of the transformer and accurate judgment of the operating status and development trend of the fault can help production personnel to scientifically arrange production plans and reduce the occurrence of accidents. The current liquid level monitoring device is inconvenient to install and disassemble. Due to impurities in the oil, the surface of the float used for liquid level monitoring is prone to accumulation of stains after long-term use, affecting the accuracy of monitoring.
