Transformer lamination manufacturer factory today: Insulation level: The insulation level of a transformer refers to the insulation performance of the transformer at the time of design. For example, a 220kV transformer means that the designed insulation voltage of the transformer is 220 kV. Cooling method: The cooling method of the transformer refers to the heat dissipation method of the transformer. For example, transformers can dissipate heat through natural cooling, forced air cooling, or forced water cooling. To sum up, the rated value on the transformer nameplate refers to some important electrical parameters and performance indicators of the transformer, which is of great significance for the selection, installation and operation of the transformer.

Rising temperature: The capacity of the transformer will decrease as the temperature rises. Therefore, it is necessary to consider the appropriate heat dissipation method and heat dissipation area when designing the transformer to ensure that the temperature rise of the transformer does not exceed the allowable range. Connection method: Different transformer connection methods, such as star, delta, etc., will also affect the capacity of the transformer. For the star connection, the capacity of the transformer can be increased by about 3 times; for the delta connection, the capacity of the transformer is relatively small. Insulation level: The insulation level of the transformer determines the insulation capability and safety performance of the transformer, and also affects the capacity of the transformer. To sum up, the capacity of the transformer is related to factors such as input voltage and output voltage, load nature, temperature rise, connection method and insulation level. When selecting a transformer, it is necessary to comprehensively consider various factors according to the actual situation to ensure the normal operation and stability of the transformer.
Epoxy resin is non – combustible, flame retardant, self – extinguishing solid insulation material, safe and clean. It is also a solid insulation material with proven insulation and heat dissipation technology for more than 40 years.Epoxy resin products can be used for dry type transformer, for insulation parts, for instrument transformer, for electrical composite parts and for room temperature curing. Epoxy resin dry transformer uses epoxy resin as insulation material. The high and low voltage windings are made of copper tape (foil), industrial epoxy resin is poured in vacuum and cured, forming a high strength FRP body structure. Insulation grade F, H. Epoxy resin dry transformer has the characteristics of good electrical performance, strong resistance to lightning impact, strong resistance to short circuit, small size and light weight. Temperature display controller can be installed to display and control the operating temperature of the transformer winding to ensure the normal service life of the transformer.
The cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When air cooled naturally, the transformer can run continuously for a long time under rated capacity. When forced air cooling, transformer output capacity can be increased by 50%. Suitable for intermittent overload operation, or emergency overload operation; Because the load loss and impedance voltage increase greatly during overload, it is in non-economic operation state, so it should not be in continuous overload operation for a long time.Welcome to inquiry price for dry type substation transformer.

The main pillar of the smart grid is the smart substation, which is not only an important hub for power transmission and distribution, but also directly affects the operational and monitoring capabilities of the smart grid through its operational safety and stability. Through the network, information can be exchanged, and the transformer can share information with the process layer and the station control layer. On the premise of ensuring product performance, the integration of monitoring, control, measurement, protection, and metering is designed to achieve the integration of transformer components with actuators, sensors, and transformers.
Impedance voltage (%): Short-circuit the secondary winding of the transformer and slowly increase the voltage on the primary winding. When the short-circuit current of the secondary winding equals the rated value, the voltage applied on the primary side is the impedance voltage. It is usually expressed as a percentage of the rated voltage. Phase number and frequency: Three-phase is represented by S, and single-phase is represented by D. The frequency f of China’s national standard is 50Hz.There are countries abroad with 60Hz (such as the United States).I. Temperature rise and cooling: The difference between the temperature of the transformer winding or upper oil layer and the temperature of the surrounding environment is called the temperature rise of the winding or upper oil layer. The limit value of the temperature rise of the oil-immersed transformer winding is 65K, and the temperature rise of the oil surface is 55K.There are also various cooling methods: oil-immersed self-cooling, forced air cooling, water cooling, tube type, sheet type, etc.
In terms of productivity, poor PQ can cause unscheduled downtime due to equipment malfunctions or system failures. This unpredictability can significantly disrupt operations, leading to lower productivity levels and potential revenue losses. Moreover, poor PQ can lead to diminished energy efficiency. Transformers operating under poor power quality conditions often require more power to function, leading to increased energy consumption and higher operating costs. The excess power demand could also strain the electrical grid, leading to further inefficiencies and disruptions. Additionally, the costs associated with repairing or replacing damaged equipment due to poor power quality can be substantial. There are also indirect costs to consider, such as those associated with investigation and troubleshooting of power quality issues.
