Description

Technical Field

[0001] The utility model belongs to the technical field of transformer high-voltage tapping, in particular to a high-voltage tapping device for a mining transformer. 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. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization. Transformers are basic equipment for power transmission and distribution and are widely used in industries such as industry, agriculture, transportation, and urban communities. The winding is the circuit part of the transformer, which is wound with double-wire insulated flat wire or enameled round wire. In a transformer with a tapped winding, each tap connection of the winding indicates that the tapped winding has a certain value of effective turns, and also indicates that there is a certain value of turns ratio between the tapped winding and any other winding with a constant number of turns.

[0003] For example, the Chinese patent with publication number CN217280378U discloses a high-voltage tapping device for a mining transformer. The patent uses a slightly inclined support plate on the clamp to make the wire clamp connected to it in an inclined state, so that it is not easy for water to accumulate on the tapping plate. Three independent tapping plates are fixed to the wire clamp by bolts, and a large gap is left between the tapping plates, which is not easy to produce water accumulation and increases the creepage distance between the two phases. It has a reasonable structure and is safe and durable.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: multiple tap plates are connected and fixed to the wire clamps by insulating bolts, and the tap plates are arranged outside the transformer when in use, and then the surface of the insulating bolts may rust due to water vapor after long-term use, and then when the tap plate is damaged, the staff may need to replace the tap plate, and at this time, the rusted insulating bolts may affect the removal of the tap plate, which may affect the use effect of the tap device.

[0006] In view of this, we propose a high-voltage tapping device for mining transformers. Utility Model Content
