Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to a transformer with a built-in lightning protection device. Background Art
[0002] The transformer uses the electromagnetic induction phenomenon. When alternating current is passed through the coil at the input end, a changing magnetic field is generated. This magnetic field will induce another coil in the iron core, thereby generating an electromotive force in the secondary coil, causing the current and voltage in the secondary coil to change. Through the design of the transformer, the high voltage at the input end is converted into a low voltage at the output end, or the low voltage is converted into a high voltage, so as to adapt to the voltage requirements of different electrical equipment. The current in the circuit can also be changed so that the current at the input and output ends can adapt to the requirements of different electrical equipment. At the same time, the circuits at the input and output ends can be isolated, which plays a role in safety isolation and electrical insulation. In order to prevent the transformer from being struck by lightning, a lightning arrester is often installed above the transformer to protect the transformer from lightning.
[0003] When a common transformer is in use, the voltage ratio between the input and output ends is changed through the transformer. A lightning arrester is often installed above the transformer to protect the transformer from lightning during use. However, the lightning protection capability of the transformer needs to be improved if the lightning arrester installed above the transformer is used to protect the transformer from lightning.
