Oil type transformer is a common device in power systems. It is mainly used to convert voltage and transmit electrical energy. The winding temperature of the transformer is an important parameter, which directly affects the operational safety and stability of the transformer. This article will explore issues related to oil-type transformer winding temperature.
First, we need to understand the significance and impact of transformer winding temperature. Transformer winding temperature refers to the temperature of the internal winding of the transformer, which is affected by factors such as external ambient temperature, load conditions, winding materials, and insulation materials. When the temperature of the transformer winding is too high, it will cause the insulation material to age, the insulation strength to decrease, and even cause insulation breakdown, thus affecting the safe operation of the transformer. Therefore, it is very important to monitor and control the transformer winding temperature in time.
Second, we need to understand how to monitor and control transformer winding temperature. At present, the commonly used method is to install temperature sensors inside the transformer windings for real-time monitoring. When the temperature exceeds the set threshold, an automatic alarm is issued and corresponding control measures are taken, such as reducing the load and increasing cooling measures. In addition, the condition of the insulation material can be evaluated through regular insulation testing of the insulating oil and windings, and problems can be discovered and maintained in a timely manner.
In addition, we also need to understand the influencing factors of transformer winding temperature. The first is the external ambient temperature. High temperature will cause poor heat dissipation of the transformer, thereby increasing the winding temperature; second is the load condition, overload operation will increase the temperature of the transformer winding; third is the winding material and insulation material, their thermal stability and insulation Performance directly affects the stability of winding temperature.
In summary, the oil-type transformer winding temperature is an important parameter and has an important impact on the safe operation of the transformer. Therefore, we need to strengthen the monitoring and control of transformer winding temperature, discover and solve problems in time, and ensure the safe and stable operation of transformers. At the same time, it is also necessary to strengthen the research on the influencing factors of transformer winding temperature to provide a better reference for the design and operation of transformers.
