We know that a liquid-cooled transformer is often used in our lives, so how to prevent the liquid-cooled transformer from burning out? Let's take a look together next.
This is the content list:
l Strengthen the measurement of electricity load
l Reasonable configuration of liquid-cooled transformer high and low voltage fuse melt
l It is not advisable to adjust the tap switch privately
l Surge arresters should be installed on both the high and low voltage sides of the liquid-cooled transformer
l Regularly check the low-voltage leads of the liquid-cooled transformer
During the peak load period of the liquid-cooled transformer, the load measurement of each liquid-cooled transformer should be strengthened, and the number of measurements should be increased if necessary. The liquid-cooled transformer with an unbalanced three-phase current should be adjusted in time to prevent the liquid-cooled transformer If the neutral wire current is too large, it is easy to burn the lead wire and cause the user equipment to burn out.
The liquid-cooled transformer's high and low voltage fuse melt configuration is unreasonable, and it is easy to cause a serious overload of the distribution transformer and burn out the liquid-cooled transformer. High and low voltage melt configuration should follow: liquid-cooled transformer with a capacity of less than 100kV·A is equipped with a fuse of 2.0 to 3.0 times the rated current. Liquid-cooled transformer transformers with a capacity above 100kV·A are equipped with a melt of 1.5 to 2.0 times the rated current. The low-voltage side fuse of the liquid-cooled transformer should be configured with a slightly larger rated current.
Due to the difference in the electrical load of the liquid-cooled transformer between winter and summer, the voltage of the liquid-cooled transformer is slightly different. To meet the voltage requirements, some rural electricians adjust the tap switch at will without performing related tests, resulting in a liquid-cooled transformer split. The switch is not in place, causing a short circuit between phases and burning out the liquid-cooled transformer.
Lightning arresters should be installed for the level of liquid-cooled transformer in the minefield. If the quality of the arrester is unqualified or is not replaced in time, the liquid-cooled transformer is easily damaged by lightning. During the thunderstorm season each year, the arrester should be sent to the repair and test department to be installed in time after passing the test, and the use of unqualified products is prohibited.
It is strictly forbidden to use the wire itself as the nose of the liquid-cooled transformer and directly connect it to the low-voltage pile head of the distribution transformer. Regularly check and strengthen the connection between the lead and the liquid-cooled transformer pile head to prevent the liquid-cooled transformer from being burnt out due to loosening. Pile head.
To make the liquid-cooled transformer operate safely for a long time without failure, as an operation manager, you must perform frequent inspections, maintenance, and measurement to find problems in time and deal with them promptly to prevent the liquid-cooled transformer from expanding and burning out of the liquid-cooled transformer.
