The 11kV 3 phase 200 kVA distribution transformerintroduction:

A11kV 3 phase 200 kVA distribution transformeris an essential piece of electrical equipment used to convert high-voltage electrical energy into low-voltage electricity for various electrical devices. This type of transformer plays a crucial role in power systems, serving as a key component for energy transmission and distribution. It accomplishes the transfer of energy and distribution balance between different electrical grids in the power system by adjusting voltage levels and transforming current forms. 10kV electrical transformers are known for their efficiency and stability, ensuring a reliable power supply.

The core components of a11kV 3 phase 200 kVA distribution transformerinclude the iron core and coils. The iron core is constructed by stacking silicon steel sheets, primarily serving to guide magnetic flux, reduce magnetic leakage, and increase magnetic flux density. Effective design and manufacturing of the iron core can significantly reduce energy losses and waste. Coils are wound with conductor wires and generate a magnetic field through the flow of electric current, facilitating the conversion of electrical energy. The design and manufacturing of coils consider factors such as current magnitude, frequency, and winding structure to ensure the transformer's normal operation and efficient energy conversion.

11kV 3 phase 200 kVA distribution transformersare equipped with a range of protective measures to ensure their safe and reliable operation. For instance, temperature protection devices are installed on the transformer. If the temperature exceeds the safety range, the power supply is automatically cut off to prevent overheating and damage to the transformer. Additionally, leakage protection devices are in place to automatically disconnect the power supply upon detecting leakage, preventing electrical accidents. These protective measures promptly identify and address transformer faults, ensuring the safe operation of the power system.

The Daily Maintenance of 11kV 3 phase 200 kVA distribution transformers

1. Power transformers often encounter issues during operation, such as oil leakage, fluctuating oil levels, abnormal temperatures, unusual sounds, and anomalies in the cooling system. Attempt to identify the causes, rectify them, and maintain proper records.

2. When the load on the power transformer exceeds the allowable normal overload value, reduce the transformer's load as necessary to prevent safety incidents.

3. In case of the following conditions, immediately disconnect the power supply to the transformer for maintenance: loud noises from within the transformer, discharge sounds, abnormal heating, fuel injection from the oil tank or safety vent, oil levels dropping to the limit indicated by the oil gauge, rapid changes in oil color, and severe damage to insulators.

4. When the power transformer's oil temperature is found to be high and corresponds to a significant decrease in oil level, refill it promptly following the prescribed procedures. If a significant oil leak causes a rapid drop in oil level, change the gas protection to only affect signaling, take immediate measures to plug the oil leak, and refill the transformer. When the transformer's oil level gradually rises due to an increase in temperature, and if the oil level at the highest temperature may exceed the oil level indicator, reduce the oil level to an appropriate level to avoid overflow.

5. For the routine maintenance of dry-type transformers, if the power can be disconnected, check for loose fasteners, and wipe off any dust. Major maintenance for medium and large transformers primarily involves measuring insulation resistance, such as high and low voltage ground resistance.
