How does a high-voltage power transformer work

High voltage transformer is a type of electrical equipment mainly used to convert voltage from the high voltage end to the low voltage end. It is mainly composed of iron core and winding. The iron core is made of highly magnetic conductive material to provide a strong magnetic circuit, while the winding is used to carry current and generate a magnetic field. The following is a brief introduction to the working principle, operation, and maintenance of high-voltage transformers.

1. Working principle:

High voltage transformers work using the principle of electromagnetic induction. When a high-voltage power supply is connected to one side of the winding, current flows through the winding, generating a magnetic field. The magnetic field passes through the iron core and then senses along the winding on the other side. According to Faraday's law, when the magnetic flux changes on the other winding, an induced electromotive force is generated. According to the winding ratio, the induced electromotive force will change the voltage at the output terminal.

2. Running process:

During operation, high-voltage transformers rely on external power sources to provide electrical energy. The voltage of the high-voltage power supply is connected to a high-voltage winding, while the low-voltage winding is connected to the equipment that uses electrical energy. When an external power source is powered on, high voltage current passes through the high voltage winding, forming a magnetic field. The magnetic field passes through the iron core and induces the voltage on the low-voltage winding. In this way, the voltage of the high-voltage power supply will be converted into low-voltage voltage and supplied to the equipment in use.

3. Maintenance:

In order to maintain the normal operation of high-voltage transformers and extend their lifespan, the following points need to be noted:

-Regularly inspect the windings and iron cores for damage, corrosion, or looseness. If there are any problems, they need to be repaired or replaced in a timely manner.

-Check the insulation status of the winding to ensure that the insulation is intact. If insulation damage is found, it must be repaired in a timely manner.

-Clean and maintain the cleanliness of the surrounding environment of the transformer to prevent dust or impurities from entering the transformer and causing malfunctions.

-Regularly inspect and replace the insulation oil inside the transformer to ensure good quality of insulation oil and maintain stable insulation performance.

-Monitor the temperature and humidity of the transformer to ensure they are within the normal range. If the temperature is abnormally high or the humidity is too high, timely measures should be taken to adjust or repair it.

The above brief introduction to the working principle, operation, and maintenance of high-voltage transformers can help understand the basic principles and operating points of high-voltage transformers.
