What is the temperature standard for the pile head of the transformer on the column

The operating temperature shall not exceed 105 ℃, and the relative temperature rise to the environment shall not exceed 65 ℃. This is the numerical value specified by the national standard and should be strictly enforced.

Why does a column mounted transformer require a temperature detection system

The temperature of the transformer pile head is a key parameter for the use status of the transformer, and how to measure the temperature of the transformer status is a problem that must be solved. With the development of social economy, the demand for power supply reliability is higher. When operating transformers for inspection and inspection, especially when measuring temperature at the pile head of the column mounted transformer, due to the insulation sheath installed on the high and low voltage pile heads of the currently installed column mounted transformer, there is a certain gap between the insulation sheath and the transformer pile head. When using infrared temperature measurement, the temperature outside the insulation sheath of the terminal post is measured, and the measurement error is large, which makes it difficult for operators to accurately judge the operation of the transformer. Eyni zamanda, due to the fact that the terminals are inside the insulation sheath, the problem of loose terminals cannot be directly reflected, and the existing hidden dangers cannot be dealt with in a timely manner, resulting in transformer operation with faults and affecting power supply reliability. In the power system, distribution transformers play a very important role. Once a fault occurs, it will directly cause losses to production and the normal life of residents.

Temperature measurement at the inlet pile head of the column mounted transformer and the outlet pile head of the transformer

In order to prevent the transformer from burning out due to high temperature, temperature measurement is generally carried out on the transformer. When the temperature is too high, the staff will inspect the transformer to ensure normal electricity consumption for production and residents. Hazırda, the temperature measurement of transformers is mainly based on the winding temperature of the transformer. Lakin, in actual use, especially during peak summer load periods, many transformers may still burn out even when the measured winding temperature is within the normal range. After investigation and analysis, it was found that the imbalance of three-phase loads can easily cause transformer overload, resulting in high temperature at the low-voltage pile head and ultimately leading to transformer burnout.

Fluorescent fiber optic temperature measurement system for column mounted transformer pile head

The fluorescent fiber optic temperature measurement device for transformer pile head adopts a direct measurement method. The customized fluorescent fiber optic probe is embedded in the pile head of the transformer on the column. Due to the good insulation of the fiber optic, the probe can be directly contacted with the hot spot, and the temperature signal of the pile head can be uploaded to the monitoring system in real time through external fiber optic. The structure is simple and can detect the temperature of the incoming and outgoing lines of the transformer pile head, thereby avoiding the overheating of the low-voltage pile head caused by three-phase load imbalance and burning the transformer, ensuring normal electricity consumption for production and residents.
