Fast-assembly fusion tube type voltage transformer used in harsh environment

Abstract

The invention is suitable for the technical field of transformers, and provides a fast-assembly fusion tube type voltage transformer used in a harsh environment. The transformer comprises a three-phase voltage transformer; the top of the three-phase voltage transformer is provided with a fusion tube; a silica gel cap is arranged on one side of the fusion tube, and the fusion tube is detachably connected with the silica gel cap; a shielding net is arranged in the fusion tube, and the shielding net is connected with the fusion tube. Through the arrangement of the fusion tube and the silica gel cap, a user can disassemble the silica gel cap to disassemble and assemble a fuse in the fusion tube; through insulation and sealing of the silicone grease and sealing of the silica gel cap, ionization leakage is effectively prevented, creepage is prevented, the device can be used in areas with high pollution grade and severe salt mist, the difference of different use environments in domestic areas is solved, and the device can be used as a general product.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a fast-installed fusion tube type voltage transformer used in a severe environment. Background technique [0002] The basic structure of a voltage transformer is very similar to that of a transformer. It also has two windings, one called the primary winding and the other called the secondary winding. Both windings are mounted or wound on the core. There is insulation between the two windings and between the winding and the iron core, so that there is electrical isolation between the two windings and between the winding and the iron core. [0003] The current voltage transformers are designed according to the pollution level, and the creepage requirements of severely polluted places are not considered in the structure. After long-term operation in coastal areas or other harsh environments, conductive substances will accumulate on the surface of the transformer, which will c...

AI Technical Summary

Problems solved by technology

For long-term operation in coastal areas or other harsh environments, conductive substances will accumulate on the surface of the transformer, which will cause creepage discharge due to insufficient insulation distance of the product, and then damage the transformer.
