Technical Field
[0001] The utility model relates to the technical field of grounding leads, in particular to a transformer core grounding lead structure. 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, secondary coil and iron core (magnetic core). It mainly includes the functions of voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. In a transformer, windings and iron cores are the main components for transmitting and converting electromagnetic energy. The safety of windings and iron cores is the key to ensuring the reliable operation of the transformer. During the operation of the transformer, the electric field formed between the charged windings and leads and the oil tank is an uneven electric field. The iron core and other metal components are in this electric field. Due to the different positions of the iron core and other metal components, the potentials are also different. When the potential difference between the two points reaches a level that can break through the insulation between them, spark discharge occurs, leading to an accident.
[0003] When installing in different scenarios, the grounding core needs to be inserted into the ground to contact it. However, in some rocky areas, the grounding core is difficult to insert due to the hard surface, which will affect the grounding effect. For this reason, we propose a transformer core grounding lead structure. Utility Model Content
