      On December 14, 2022, the order of S9 oil immersion transformers exported to South Africa was issued. The production of this order lasted 43 days, with a total of 26 units. The 12 units are 2000kva, the 7 units are 500kva, and the 7 units are 200kva. Customers require a 2000kva oil pillow with a voltage of 11/0.69kV, 5%~ 6.5%in impedance, and the coil is copper, and the 5th gear distribution switch. Hengfengyou issued three complete design drawings with capacity before production, and was put into production after confirming it by customers. After confirming the order, the customer wanted to change the color of the transformer, and changed from the original C12 light green to the B05 seagull ash. At the same time, he affirmed the professional and patience of Hengfengyou. Now that the order has passed the test and went to the port smoothly, it is installed. What are the problems that pay attention to after installing the on -site installation?

      After the transformer was installed on the spot. Add metal fence and ground line. Don't close the fence. Cut off in the right place. When connecting the ground wire, do not form a closed loop under the transformer. For transformers running indoor, the environmental temperature of the room must be checked frequently. When the transformer works, the heat generated by the transformer must be assigned in time. If the transformer is installed indoors, run the inspector, please observe the operating environment temperature of the transformer room at any time. In order to avoid excessive ambient temperature caused by poor heat dissipation, a temperature alarm device is set in the transformer room if necessary. If the indoor ventilation is poor, the temperature is too high, and the alert should be issued in time. The operating noise of the transformer. Due to its own structural characteristics, the dry hollow transformer is very small, generally about 50 decibels. The increase in noise in the operation of the transformer is usually due to the following reasons: there is no tightening screw, screw, nut, wires and other metals in the installation of the ventilation pipe of the transformer.
      Because the wiring end of the transformer is a strong magnetic field, if the cable wiring is used, the cable head is inserted by the wiring end and is not pushed, and the wires are relaxed under the strong magnetic field. Mix the surface of the transformer regularly. The cleaning method can be wiped with appropriate pressure water guns on sunny days. Note: If the surface of the transformer is coated with RTV coatings, the cleaning method should be cleaned with proper pressure scattering water guns on sunny days to avoid damaging the hydrophobicity of the RTV coating surface. The above is the problem that should be paid attention to when the transformer is installed.
