Abstract

The invention provides a multi-step multi-layer shielding voltage transformer, which comprises a shell, an iron core, a coil assembly and an insulation assembly, wherein the iron core is rectangular and is vertically arranged in the shell, the coil assembly comprises a first winding and a second winding, the insulation assembly comprises a first insulation layer and a second insulation layer, the first winding is wound on the iron core, the second winding is wound on the outer side of the first winding, the first insulation layer is fixedly arranged between the first winding and the second winding, and the second insulation layer is fixedly arranged on the outer side of the second winding. A purpose of the invention is to provide a novel voltage transformer, so that the problem that in the prior art, epoxy resin insulation cannot meet the insulation requirement under high voltage is solved.

Description

technical field [0001] The invention relates to the technical field of voltage transformers, in particular to a multi-step and multi-layer shielded voltage transformer. Background technique [0002] Similar to a transformer, a voltage transformer is an instrument for transforming voltage, but compared with a transformer, a voltage transformer is mainly used for instrumentation and electrical protection. At present, most voltage transformers and current transformers below 35KV use rings Oxygen resin insulation structure, and the insulation strength of epoxy resin has a limit, and the insulation level of 35KV has reached the insulation limit of epoxy resin, so most of the voltage transformers of 66KV and above use oil-gas insulation, but the cost of oil-gas insulation is high and maintenance is more difficult. At the same time, oil-gas insulation is not conducive to environmental protection. Therefore, it is necessary to design a new type of voltage transformer to solve the pr...
