What is a transformer on-load tap changer (OLTC)?
This is a device that adjusts the voltage ratio of a transformer when it is loaded. It allows the voltage to be adjusted to maintain a stable output despite fluctuations in input voltage or load conditions. OLTC works by changing the tap position on the transformer winding, effectively changing the turns ratio and thus the voltage. This ensures that the electrical system remains stable and efficient, preventing damage and maintaining optimal performance under different load conditions.
Why does the oil of the transformer on-load tap changer need to be filtered and purified?
Because the oil may contain impurities such as free carbon, metal particles and moisture. These impurities affect the insulation properties of the oil and the stability of the switchgear, shortening the life of the equipment. Through filtering and purification, these harmful substances can be removed, thereby improving the insulation strength, extending the service life of the equipment, and reducing the frequency of maintenance and the risk of power outages.
What solutions do transformer users need?
REXON's ZYL series on-load tap changer online oil filter is mainly used for bypass oil circulation filtration of transformer on-load tap changers. As well as various voltage combinations and compound on-load tap changers with independent oil chambers running in transformers.
This online oil filter is used in conjunction with transformer on-load tap changers. It can effectively remove impurities such as free carbon and metal particles in the insulating oil of the on-load tap changer under normal operating conditions of the transformer system, and can reduce trace moisture, ensure the breakdown voltage and life of the oil, thereby reducing power outages and maintenance times, extending the maintenance cycle, and effectively improving the safety and reliability of the on-load tap changer.
At the same time, the REXON on-load tap changer online oil filter adopts Siemens programmable controller technology, with automatic, timed start, remote control, alarm and other functions. It brings users a convenient and efficient use experience and greatly improves on-site work efficiency.
