Description
Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to a transformer which is easy to repair. Background Art
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and provide safety isolation. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electric potential can be induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux interlinked with the coil changes. This is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance.
[0003] When using a transformer, it is easy to have the following problems: circuit failure (short circuit at the transformer outlet); cracking at the welding joint, short circuit between phases, short circuit in turn, grounding fault of winding, etc.; transformer oil leakage; unstable connection of the current-carrying joint of the transformer, which causes the temperature at the joint to rise rapidly, even exceeding the ignition point of the joint, causing the joint to burn out. These problems seriously affect the safe and stable operation of the power transformer, so the transformer needs to be repaired. When the transformer is in use, it is generally fixedly installed in the transformer box. When it needs to be repaired, it needs to be manually disassembled and the transformer body is moved out of the transformer box. Due to the large mass of the transformer, manual disassembly and movement requires a lot of time and energy, and the efficiency is low. Therefore, a transformer that is easy to repair is needed.

[0009] As an improvement, both left and right side walls of the installation box are embedded with radiators, which can cooperate with the working process of the transformer body to dissipate heat.
